2005 VOLVO V70 buttons

Four-C
R-models are 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 buttons in the center of the dashboard (see the illustration above) can be used at any time to switch between three
driving modes: Comfort, Sport, or Advanced 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.
The effect of pressure on the throttle pedal is linked to the selected mode, where the Advanced sport setting provides
the most immediate throttle response.
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 still be active when the engine is
restarted.
Sport
In this 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 still will be active when the engine is
restarted.
Advanced sport
In this mode, movement of the shock absorbers is minimal, response from pressure on the throttle pedal is more direct,
and body sway in curves or when cornering is sharply reduced.
If Advanced sport mode was selected when the engine was switched off, Sport mode will be active when the engine
is restarted.

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.
ProCarManuals.com

• 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.

Switch on/off
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.
