2007 Volvo XC70
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
pattern, load-, speed-, traction- , temperature-, and treadwear rating. \
Never drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire inflation pressure placards, located on the driver's side B-pil\
lar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the in\
side of the fuel filler door on
Canadian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-
sized tire as soon as possible. Do not drive on the temporary spare at s\
peeds above 50 mph (80km/h) or
for distances greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

Four-C active chassis system
Four-C active chassis
The FOUR-C (Continuously Controlled Chassis Concept) active chassis sy\
stem, consisting of Comfort
and Sport modes, is available as an option.
NOTE: The V70 R has a standard FOUR-C system consisting of Comfort, Sport, an\
d Advanced sport
modes. The buttons for controlling these driving modes are located in ce\
nter instrument panel, above the
ventilation system panel vents, see the illustration in the right column\
. These buttons can be pressed at
any time to change driving modes. An indicator light in the selected but\
ton will come on to indicate the
driving mode that is currently selected.
This system is based on a number of sensors that continuously monitor fa\
ctors such as the vehicle'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 ad\
justment of each shock
absorber. The system adjusts the stiffness of the shock absorbers approx\
imately 100 times per second
Use the button in the center console to switch between the driving modes\
Comfort and Sport. This can
be done at any time.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock abs\
orption and the softest ride.

l The audio system's volume will be reduced.
l An intermittent signal will be audible from the speakers to indicate tha\
t 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)
l At a distance of approximately 1 foot (30 cm), the signal will become \
constant. If objects are close to
both the front and rear bumpers, the signal will alternate between the f\
ront and rear speakers.
Deactivating the system(s)
- Press the Park assist button on the center console (see
page 55) to temporarily deactivate the system(s).
- The indicator light in the button will go out when the system(s) hav\
e been deactivated.
- If the vehicle is equipped with front and rear park assist, both syste\
ms will be deactivated by pressing
the button.
Park assist will be automatically reactivated the next time the engine i\
s started.
NOTE: It may be necessary to deactivate one or both of the park assist systems\
in certain cases.
l Rear park assist: towing a trailer, carrying bicycles in a rear-mounted carrier, etc, co\
uld trigger the
rear park assist system's sensors.
l 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 the yellow warning symbol illuminates and a message is shown in the \

r bumpers should be kept clean.
They can be cleaned with car washing detergent and a sponge.

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