Fuel requirements

Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating AKI of 91, or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).

Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be effective in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with the service station operator.

Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only". Leaded gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in emission test failure for misfueled vehicles.

NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected, and the Check Engine light (malfunction indicator lamp) located on your instrument panel may light. If this occurs, please return your vehicle to an authorized Volvo retailer for service.

Gasoline containing alcohol and ethers

"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must still be met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as Ethyl alcohol, or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be used.


CAUTION!
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the New Vehicle Limited Warranty.

pg. 75 Fuel requirements

Carbon Monoxide - Important Warning
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the vehicle to your retailer for correction.

Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the exhaust emission control systems on your car, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you live in an area where you must fill your own gas tank, take precautions. These may include:

  • standing upwind away from the filler nozzle while refueling
  • refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
  • wear neoprene gloves while handling a fuel filler nozzle.

    Use of Additives
    With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store-bought additives to your car's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.

    pg. 76 Refueling


    Refueling
    The fuel tank holds approximately 18 US gal. (68 liters) with sufficient volume left over to accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat less than the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid vapor pressure" characteristics, and terrain can affect the fuel pump's ability to supply the engine with an adequate supply of fuel. Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the fuel warning light comes on.

    Fuel filler door
    Press the button on the light switch panel (see illustration on page 34) when the car is at a standstill to unlock the fuel filler door. Please note that the fuel filler door will remain unlocked until the car begins to move forward. An audible click ill be heard when the fuel filler door relocks.
    If you intend to leave your car while it is being refueled, this feature enables you to lock the doors/trunk while leaving the fuel filler door unlocked.
    You can also keep the car locked if you remain inside it during refueling. The central locking button does not lock the fuel filler door. Be sure the fuel filler door is not obstructed and is completely closed after refueling.

    Open the fuel filler cap slowly during hot weather conditions.

    NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not compatible with the fuel filler neck on cars equipped with the evaporative control system. Please refer to page 137 for additional information.

    WARNING!
    Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may cause a spark that could ignite gasoline fumes, resulting in fire and injury.


    CAUTION:
  • Do not refuel with the engine running *. Turn the ignition off or to position I. If the ignition is on, an incorrect reading could occur in the fuel gauge.
  • After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
  • Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control systems.
  • Avoid spilling gasoline during refueling. In addition to causing damage to the environment, gasolines containing alcohol can cause damage to painted surfaces, which may not be covered under the New Vehicle Limited Warranty.
  • Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the New Vehicle Limited Warranty.

    * If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault.
    However, your vehicle's performance will not be affected. Use only Volvo original or approved fuel filler caps.

    pg. 77 Starting the engine

    Starting the engine

    1. Fasten the seat belt.

    WARNING!
    Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can be depressed completely. Adjust the seat if necessary. See page 54.

    2. Apply the parking brake, if not already set. The gear selector is locked in the (P)ark position (SHIFTLOCK).

    3. Without touching the accelerator pedal, turn the ignition key* to the starting position. Allow the starter to operate for up to 5 seconds (turbo: 10 seconds). Release the key as soon as the engine starts. If the engine fails to start, repeat this step.

    NOTE: On certain models, when the car is started, idle speed may be noticeably higher than normal for a short period, depending on the temperature of the engine.
    This has been done to help bring components in the emission control system to their normal operating temperature as quickly as possible, which enables them to function normally.

    For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the starting position. Release the pedal slowly when the engine starts.

    4. To release the gear selector from the (P)ark position, the engine must be running (or the ignition key must be in position II) and the brake pedal must be depressed. While keeping firm pressure on the brake pedal, release the parking brake.

    5. Select the desired gear. The gear engages after a very slight delay which is especially noticeable when selecting R.

    NOTE:

  • Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the (P)ark position before the key can be removed from the ignition switch.
  • When starting in cold weather, the transmission may shift up at slightly higher engine speeds than normal until the automatic transmission fluid reaches normal operating temperature.

    CAUTION:
  • The engine should be idling when you move the gear selector. Never accelerate until after you feel the transmission engage! Accelerating immediately after selecting a gear will cause harsh engagement and premature transmission wear.
  • Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of the automatic transmission fluid.
  • Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to prevent engine damage.

    WARNING!

  • Always place the gear selector in Park and apply the parking brake before leaving the vehicle. Never leave the car unattended with the engine running.
  • Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
  • * Your car is equipped with an electronic start inhibitor (immobilizer). The keys you received with your car are specially coded. The code in the key is transmitted to an antenna in the ignition switch where it is compared to the code stored in the start inhibitor module. The car can only be started if a properly coded key is used.
    If two of the keys to your car are close together, e.g., on the same key ring, when you try to start the car, this could cause interference in the immobilizer system and result in the car not starting. If this should occur, remove one of the keys from the key ring before trying to start the car again.

    pg. 78 Automatic transmission - five speed





    P (Park)
    Use this position when starting the engine or parking the car.
    Never use P while the car is in motion.
    The parking brake should also be set whenever the car is parked.
    The gear selector is mechanically locked in the P position (SHIFTLOCK). To release the gear selector from this position, the engine must be running (or the ignition key must be in position II) and the brake pedal must be depressed.

    WARNING!
    Never leave the car unattended when the engine is running. If, by mistake, the gear selector is moved from P, the car may start moving.

    R (Reverse)
    Never engage R while the car is moving.

    N (Neutral)
    Neutral - no gear engaged. Use the parking brake.

    D (Drive)
    D is the normal driving position and should be used as often as possible to help improve fuel economy. The car should not be moving when shifting from R to the D position.

    4 (Intermediate gear)
    The transmission will shift automatically between gears 4, 3, 2 or 1 from this position. The transmission cannot shift up to (D)rive from fourth gear.

    3 (Intermediate gear)
    The transmission will shift automatically between gears 3, 2 and 1 from this position. The transmission cannot shift up to fourth gear or (D)rive from third gear.

    L (Low gears)
    The transmission is locked in gears 1 and 2 when the selector is in this position.

    NOTE:
    · Gears 4, 3, or L can be used if you are driving in a mountainous area, towing a trailer or to increase engine braking effect.
    · The transmission has a built-in limiter designed to help prevent excessive engine speeds (high rpm) when gears 4, 3, or L are selected.

    pg. 79 Automatic transmission - five speed

    Automatic transmission - shift gate positions
    The gear selector can be moved freely between N and D.
    Depressing the button on the front of the gear selector knob enables you to move the gear selector to positions P, R, N, D, 4, 3 and L.

  • Mode W will only function if the gear selector is in the (D)rive position.
  • Press the button at the base of the gear selector to engage/disengage this driving mode (see illustration).
  • An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument panel (see page 27).
  • This mode may be selected for starting/moving off on slippery roads.

    Kickdown
    Automatic shift to a lower gear (kickdown) is achieved by depressing the accelerator pedal fully and briskly. An upshift will occur when approaching the top speed for a particular gear or by releasing the accelerator pedal slightly.
    Kickdown can be used for maximum acceleration or when passing at highway speeds.

    Cold starts
    When driving before the engine has reached its normal operating temperature, the transmission will shift up at slightly higher engine speeds to heat the three-way catalytic converter as quickly as possible.

    pg. 80 Automatic transmission (Geartronic)



    P (Park)
    Use this position when starting the engine or parking the car.
    Never use P while the car is in motion.
    The parking brake should also be set whenever the car is parked.
    The gear selector is mechanically locked in the P position (SHIFTLOCK). To release the gear selector from this position, the engine must be running (or the ignition key must be in position II) and the brake pedal must be depressed.

    WARNING!
    Never leave the car unattended when the engine is running. If, by mistake, the gear selector is moved from P, the car may start moving.

    R (Reverse)
    Never engage R while the car is moving forward.

    N (Neutral)
    Neutral - no gear engaged. Use the parking brake.

    D (Drive)
    D is the normal driving position and should be used as often as possible to help improve fuel economy. The car should not be moving when shifting from R to the D position.

    Kickdown
    Automatic shift to a lower gear (kickdown) is achieved by depressing the accelerator pedal fully and briskly. An upshift will occur when approaching the top speed for a particular gear or by releasing the accelerator pedal slightly.
    Kickdown can be used for maximum acceleration or when passing at highway speeds. Kickdown does not function when the transmission is in the manual shift (geartronic) mode (see next page).


    Shift gate positions

    Automatic transmission - shift gate positions
    You can move the gear selector freely between the (MAN)ual and (D)rive positions while driving.
    Depress the button on the front side of the gear selector knob to move between the R, N, D and P positions.
    Please see the following page for information on using the Geartronic manual shift mode.

    pg. 81 Automatic transmission (Geartronic)

    Manual shifting - Geartronic
    You can move the gear selector freely between the (MAN)ual and (D)rive positions while driving. Gears 2, 3, 4 and 5 have a "lock-up" function which reduces engine speed and helps save fuel.
    The currently selected gear will be displayed in the instrument panel (see page 27).

  • To access the (MAN)ual shifting position from (D)rive, pull the gear selector back slightly from D and move it to the left to MAN.
  • To return to the (D)rive position from MAN, move the gear selector to the right and push it forward to the (D)rive position.

    While driving
    If you select the (MAN)ual position while driving, the gear that was being used in the (D)rive position will also initially be selected in (MAN)ual position.

  • Move the gear selector forward (toward "+") to shift to a higher gear or rearward (toward "-") to shift to a lower gear.
  • If you hold the gear selector toward "-", the transmission will downshift one gear , and will utilize the braking power of the engine. If the current speed is too high for using a lower gear, the downshift will not occur until the speed has decreased enough to allow the lower gear to be used.
  • If you slow down to a very low speed, the transmission will automatically shift down.
  • When starting in the (MAN)ual position, 3rd gear is the highest gear that may be selected.

    NOTE: Kickdown (see previous page) does not function when the transmission is in the manual shift (geartronic) mode. The gear selector must be in D (Drive) position.


    W Winter/Wet driving mode - enhanced vehicle traction

  • Mode W will only function if the gear selector is in the (D)rive position.
  • Press the button at the base of the gear selector to engage/disengage this driving mode. The position of this button may vary slightly on certain models.
  • An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument panel (see page 27).
  • This mode may be selected for starting/moving off on slippery roads.

    pg. 82 Four-C active chassis system



    Four-C (option)
    Your car can be optionally equipped with the Four-C (Continuously Controlled Chassis Concept) system.

    This system is based on a number of sensors that continuously monitor factors such as the car's lateral and vertical movements, speed, and movements of the wheels. The sensors receive data up to 500 times per second, which is used to provide extremely fast and precise adjustment of each shock absorber. The system adjusts the stiffness of the shock absorbers approximately 100 times per second.

    The button in the center console (see the illustration on page 31) can be used at any time to switch between the two driving modes: Comfort or Sport.

    The system then adjusts the stiffness of the shock absorbers accordingly, for example when the type of road changes, or if the driver wishes to change driving style. This adjustment takes place instantaneously.

    Comfort
    The Comfort mode chassis setting offers the greatest amount of shock absorption and the softest ride. This mode is recommended for long-distance driving, or when driving in slippery conditions.

    If Comfort mode was selected when the engine was switched off, this mode will be active when the engine is restarted.

    Sport
    An indicator lamp in the button will come on when this mode has been activated.

    In Sport mode, shock absorption is stiffer to reduce the car's body sway during cornering and to provide more immediate steering response.

    If this setting was selected when the engine was switched off, Sport mode will be active when the engine is restarted.

    pg. 83 Front/rear park assist (option/accessory)


    A - front (accessory as available), B - rear (option)

    Front/rear park assist
    The park assist system(s) are designed to assist you when driving into parking spaces, garages, etc. They utilize ultrasound sensors located in the bumpers to measure the distance to a vehicle or other object, or a person who may be close to the front or rear of the vehicle.

    When is park assist active?
    Front:
    the system is active from the time the engine is started until the car exceeds a speed of approximately 10 mph (15 km/h).
    Rear: when the engine is running and reverse gear is selected.

    NOTE:
    · If the vehicle is equipped with front and rear park assist, both systems will either be activated or deactivated together. They cannot be used separately.
    · The indicator light in the button (see the illustration on page 31) will light up to indicate that park assist system(s) are activated.

    When park assist is actively working:
    1. The audio system's volume will be reduced.
    2. An intermittent signal will be audible from the speakers to indicate that you are approaching a person, object, parked vehicle, etc.

    The signals begin when the distance between the bumper and the object is:
    Rear: approximately 5 feet (1.5 meters)
    Front: approximately 2.5 ft (0.8 meters)
    3. At a distance of approximately 1 foot (30 cm), the signal will become constant.

    Deactivating the system(s)
    · Press the Park assist button on the center console (see page 31) to temporarily deactivate the system(s).
    · The indicator light in the button will go out when the system(s) have been deactivated.
    · If the vehicle is equipped with front and rear park assist, both systems will be deactivated by pressing the button.

    NOTE:
    It may be necessary to deactivate one or both of the park assist systems in certain cases.
    · Rear park assist: towing a trailer, carrying bicycles in a rear-mounted carrier, etc, could trigger the rear park assist system's sensors.
    · Front park assist: it may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's sensors.

    Faults in the system
    If a fault should occur in the system, the LED in the button will be switched off and a message will be displayed in the text window.

    Cleaning the sensors
    For the system to function properly, the sensors in the front and/or rear bumpers should be kept clean. They can be cleaned with car washing detergent and a sponge.

    WARNING!
    These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to replace the driver's attention and judgement.

    pg. 84 Driving economy

    Economical driving conserves natural resources
    Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of your vehicle to immediate traffic conditions. Observe the following rules:

  • Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
  • Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal operating temperature.
  • Drive carefully and avoid rapid acceleration and hard braking.
  • Do not exceed posted speed limits.
  • Avoid carrying unnecessary items (extra load) in the car.
  • Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
  • Remove snow tires when threat of snow or ice has ended.
  • Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
  • Avoid using automatic transmission kickdown feature unless necessary.
  • Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an additional load on the engine. However, at higher driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed than with the air conditioning off and the windows open.
  • Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.

    Other factors that decrease gas mileage are:

  • Dirty air cleaner
  • Dirty engine oil and clogged oil filter
  • Dragging brakes
  • Incorrect front end alignment

    Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.

    NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using "kickdown" to help improve fuel economy.

    Cooling system
    The risk for engine overheating is greatest, especially in hot weather, when:

  • Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
  • Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
  • To avoid overheating, the following rules should be followed:
    Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly terrain.
  • Reduce speed when towing a trailer up long, steep inclines. The risk of overheating can be reduced by switching off the air conditioning system for a short time.
  • Do not let the engine idle unnecessarily for prolonged periods.
  • Do not mount auxiliary lamps in front of the grill.

    When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into, or stays continually in, the red section), the following precautions should be taken:

  • Switch off the air conditioning system.
  • Pull off the road, away from traffic, stop the car and put the gear selector into Park. Do not stop the engine!
  • Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed) until the temperature begins to drop.
  • If the warning light in the center of the instrument panel is red, and the message "Coolant level low stop engine" is displayed, switch off the engine as soon as possible.

    WARNING!
    Do not remove coolant expansion tank cap. The coolant will be extremely hot.

    If necessary, see page 138 for information on checking and topping-up the coolant level.
