All Wheel Drive (AWD) - general
information
Your Volvo can be equipped with permanent
All Wheel Drive, which means that power is
distributed automatically between the front
and rear wheels. Under normal driving condi-
tions, most engine's power is directed to the
front wheels. However, if there is any tendency
for the front wheels to spin, an electronically
controlled coupling distributes power to the
wheels that have the best traction.
Tire dimensions
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 plac-
ards, 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 mod-
els.
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 (80 km/h) or for distances greater than
50 miles (80 km).
Never install snow chains on a temporary
spare.
