Sun visor: The sun roof also features a sliding sun visor. The visor slides back automatically when the sun roof is
opened and also slides back slightly when the sun roof is opened to the ventilation position. The visor must be closed
manually.
CAUTION: Do not close the sun visor when the sun roof is in the ventilation position as this could damage the
mechanism.
NOTE:
The electrically -operated sun roof has an overload protecting circuit breaker (fuse no. 37) which is activated when an
object blocks the sun roof. Should this occur, remove the object and wait 20 seconds for the circuit breaker to reset.
The sun roof should then function normally. Also check fuse no. 35.
WARNING! The sun roof must never be obstructed in any way when in operation.

General information

Your vehicle is equipped with tires according to the tire information label located on the rear facing side of the
right front door.
The following is an example of a tire designation code 225/50R16:
225 = tire width in mm.
50 = tire profile. This is the relationship (in percent) between the section height and the width of the tire.
R = radial tires.
16 = diameter in inches.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces. Certain models are
equipped with "all-season" tires, which provide a somewhat higher degree of winter roadholding on slippery
surfaces than tires without the "all-season" rating. However, for optimum road holding on icy or snow covered
roads - we recommend suitable winter tires on all four wheels. 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.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
To improve tire economy:
ProCarManuals.com

Maintain correct tire pressure.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
If the wheels are rotated, they should be kept on the same side of the car so that they revolve in the same direction
as prior to rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
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 unbalanced 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.
CAUTION: The car must not be driven with wheels of different dimensions. The use of different size wheels can
seriously damage your car's transmission.
pg. 77 Wheels and tires (cont.)
Snow chains

Snow tire chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
Snow chains may be mounted on tire dimension 195/65R15. Tire dimension 205/55R16 requires a special type of
snow chain. Consult your Volvo retailer. Snow chains may not be used on 205/55R16 tires.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original tires
and wheels, chains in some cases CANNOT be used. Snow chains cannot be used on those turbo-charged models fitted
with all-season tires 225/50R16 or 225/45R17 or 225/40R18. Sufficient clearances between chains and brakes,
suspension and body components must be maintained.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used.
Consult your Volvo retailer for additional snow chain information.
CAUTION:
Check local regulations regarding the use of snow chains before installing.
Always follow the chains manufacturer's installation instructions carefully. Install chains as tightly as possible and
re-tighten periodically.
Never exceed the chain manufacture's specified maximum speed limit. (Under no circumstances should that limit
be higher than 30 mph (45 km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
The handling of the vehicle can be adversely affected when driving with chains. Avoid fast or sharp turns as well
as locked wheel braking.
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
ProCarManuals.com

different design as this could also negatively affect overall tire road grip. Volvo recommends 195/65 R15 winter tires
on 15" steel wheels on all C70 models including those equipped with 16", 17" or 18" wheels.
Winter tires wear more quickly on dry roads in warm weather. They should be removed when the winter driving
season has ended.
Studded tires should be run-in 300-600 miles (500-1000 km) during which the car should be driven as smoothly as
possible to give the studs the opportunity to seat properly in the tires. The car tires should have the same rotational
direction throughout their entire lifetime. In other words, if you wish to rotate the wheels, make sure that the same
wheels are always on the same side of the car.
NOTE: Please consult state or local regulations restricting the use of studded winter tires before installing such tires.
* Where permitted
pg. 78 Wheels and tires (cont.)
Checking and correcting tire pressure
Check the tire pressure when refueling.
The tire pressure should be corrected only when the tires are cold.
With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle Loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label* located on the rear facing edge of the passenger's door. This label lists both the tire and vehicle
design limits.
Do not load your car beyond the load limits indicated.
* Please note that the tire information label indicates pressures for both comfort and fuel economy.

Uniform tire quality grading

ALL PASSENGER CAR TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded at 150 would wear one and one half (1 1/2) times as
ProCarManuals.com

well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
service practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
WARNING! The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law.
WARNING! The temperature grade for this tire is established for a tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup
and possible tire failure.
