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.
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:
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.

Refueling
The fuel tank holds approximately 21.1 US gal. (80
liters) on T6 models, or 18 US gal. (68 liters) on the S80 All Wheel Drive and the
S80 2.5T Front Wheel Drive 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 131 for additional information.
WARNING! |
* 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.
Starting the engine
1. Fasten the seat belt.
WARNING! |
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:
WARNING! |
* 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.

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.

(50 km/h), the transmission will first shift to
second gear and then to first gear at lower
speeds.
NOTE: The intermediate and low gears can be used for:
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.
Automatic transmission - adaptive system
The automatic transmission is controlled by an adaptive system that constantly monitors
the way in which the transmission functions. It senses and adapts each gear shift for
optimal performance.


W Winter/Wet driving mode - enhanced vehicle traction
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.

P (Park)

Automatic transmission - adaptive system
The automatic transmission is controlled by an adaptive control system that
constantly monitors the way in which the
transmission functions. It senses and adapts each gear shift for optimal performance. The system also monitors your particular driving style
and adapts gear shifting accordingly.
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.
Manual shifting - Geartronic
You can move the gear selector freely between the
(MAN)ual and (D)rive positions while driving. Gears 2, 3, and 4
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).
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.
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.
* Models with a 5-cylinder turbo engine have a 5-speed transmission. Fifth gear also has the lock-up function.

W Winter/Wet driving mode - enhanced vehicle traction
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.

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.
