2007 Volvo V70
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-pillar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the inside 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 speeds 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 system, 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, and Advanced sport
modes. The buttons for controlling these driving modes are located in center 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 button will come on to indicate the
driving mode that is currently selected.
This system is based on a number of sensors that continuously monitor factors 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 adjustment of each shock
absorber. The system adjusts the stiffness of the shock absorbers approximately 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 absorption and the softest ride.
