The audio system in your car is operated with the buttons and knobs in the system's front panel. Certain functions, such as adjusting the volume, changing radio stations or tracks on a CD, etc, can also be controlled with the optional steering wheel-mounted keypad.

The audio system is available in two versions:

HU-650
Features: AM/FM radio, single-disc CD player, 4x25W output, six speakers.

HU-850
Features: AM/FM radio, integrated 6-disc CD changer, 4x50W or 4x70W output plus 25W Dolby Pro Logic II, eleven speakers.
A subwoofer mounted under the floor in the cargo area is available as an option. Consult your Volvo retailer.

Compact disc care
• Before using a new disc for the first time, remove any burrs in the center/outer edge by running the stem of a pen or similar object around the hole/edge of the disc.
• Use high quality discs only.
• Keep the discs clean. Wipe them with a soft, clean, lint-free cloth, working from the center outwards. If necessary, dampen the cloth with a neutral soap solution. Dry thoroughly before using.
• Never use cleaning spray or antistatic liquid. Use only cleaners specifically made for CDs.
• Use discs of the correct size only (3.5" discs should never be used). The discs should conform to the norms EN60908 (IEC60908).
• Do not put tape or labels on the disc itself.
• Volvo does not recommend the use of plastic outer rings on the disc.
• Condensation may occur on discs/optical components of the changer in cold winter weather. The disc can be dried with a clean, lint-free cloth. Optical components in the CD changer may, however, take up to one hour to dry off.
• Never attempt to play a disc which is damaged in any way.
• When not in use, the discs should be stored in their covers. Avoid storing discs in excessive heat, direct sunlight or dusty locations.

Press the knob to switch on or turn off the radio.

Volume control
Turn the knob clockwise to increase volume. Volume control is electronic and does not have an end stop. If you have a key pad in the steering wheel, increase or decrease the volume with the + or - buttons.

Volume control - ALARM
If a CD is playing when the radio receives an alarm bulletin (available in certain areas only), the CD player enters pause mode. The bulletin is broadcast at the volume selected for this type of message.
After the bulletin has been completed, the audio system reverts to the originally selected sound source (radio or CD), which is played at the volume that was selected for that source.
If the bulletin volume is adjusted while the bulletin is being broadcast, this new volume is saved and used for subsequent bulletins.

Volume control - Subwoofer
Turn the knob clockwise to increase volume.
Turn the knob counterclockwise to lower volume or switch off the subwoofer.
When the knob is in the middle, bass effect is "equalized".
