1998 VOLVO C70 suspension

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

Oil quality

Meeting API specification SG, SG/CD, SH or Energy Conserving (EC) II
For best fuel economy and engine protection, consult with your authorized Volvo retailer for recommended oils. Oil
with a different quality rating may not provide adequate engine protection. Synthetic oils complying with oil quality
requirements are recommended for : driving in areas of sustained temperature extremes (hot or cold), when towing a
trailer over long distances or for prolonged driving in mountainous areas.
Extra oil additives must not be used unless advised by an authorized Volvo retailer.
NOTE: SAE 15 W -40 oil should only be used in extreme operating conditions such as trailer towing in sustained
ambient temperatures over 104° F (40° C). However, SAE 10W -30 synthetic oil would be a better alternative in such
conditions.
SAE 15W-30 should not be used under normal operating conditions.
