When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's road-holding and handling
characteristics.
NOTE:When storing wheel/tire assemblies (e.g.
winter tires and wheels), either stand the
assemblies upright or suspend them off the
ground. Laying wheel/tire assemblies on their
sides for prolonged periods can cause wheel and/
or tire damage.
Wear indicator
The tires have a so-called "wear indicator" in the
form of a number of narrow strips running across
or parallel to the tread. When approx. 1/16" (1.6
mm) is left on the tread, these strips show up and
indicate that the tire should be replaced.
Tires with less than 1/16" (1.6 mm) tread have a
very poor grip in rain or snow.
All tires become warm during use. After cooling,
when the vehicle is parked, the tires have a
tendency to distort slightly, forming flat spots.
These flat spots can cause vibrations similar to the
vibrations caused by imbalanced wheels.
They do, however, disappear when the tire warms
up. The degree to which the flat spots form
depends on the type of cord used in the tire.
Remember that, in cold weather, it takes longer
for the tire to warm up and consequently longer
for the flat spot to disappear.

Snow chains
Snow tire chains can be used on your Volvo with
the following restrictions:
l Snow chains should be installed on rear wheels
only. Use only Volvo approved snow chains.
l Snow chains can only be used on tires which
are not wider than 195 mm.
l Sufficient clearances between chains and
brakes, suspension and body components must be
maintained.
l Some strap-on type chains will interfere with
brake components and therefore CANNOT be
used.
Consult your Volvo retailer for additional snow
Snow tires, studded tires*
Tires for winter use:
Owners who live in or regularly commute
through areas with sustained periods of snow
or icy driving conditions are strongly advised
to fit suitable winter tires to help retain the
highest degree of traction.
It is important to install winter tires on all four
wheels to help retain traction during cornering,
braking and accelerating. Failure to do so could
reduce traction to an unsafe level or adversely
affect handling. Do not mix tires of different
design as this could also negatively affect overall
tire road grip.

Volvo supports Voluntary Mechanic
Certification by the A.S.E. Certified
mechanics have demonstrated a high
degree of competence in specific
areas. Besides passing exams each
mechanic must also have worked in
the field for two or more years before
a certificate is issued. These
professional mechanics are fully able
to analyze vehicle problems and
perform the necessary service
procedures to keep your Volvo at peak
operating condition.
Note that the above pertains to USA
only.
Your new Volvo comes with a four
year road assistance program named
ON-CALL. Additional information,
features, and benefits are described in a
separate information package in your
glove compartment.
If you have misplaced your package,
