1999 VOLVO S70 fuel type

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:
Maintain correct tire pressure. See the tire pressure label on the inside of the fuel tank cover.
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 or with a spare tire other than the one
that came with the car. The use of different size wheels can seriously damage your car's transmission. *
* This also applies to models equipped with All Wheel Drive (AWD). pg. 87 Wheels and tires (cont.)
Snow chains

The distributor ignition system operates at very high voltages. Special safety precautions must be followed to
prevent injury. Always turn the ignition off when:
Replacing distributor ignition components e.g. plugs, coil, etc.
Do not touch any part of the distributor ignition system while the engine is running. This may result in
unintended movements and body injury.
Replacing spark plugs
The spark plugs should be changed every 30,000 miles (48,000 km). However, city driving or fast highway driving
may necessitate changing after 15,000 miles (24,000 km) of driving. When installing new plugs, be sure to fit the right
type and use correct torque, see "Specifications". When changing the plugs, check that the suppressor connectors are in
good condition. Cracked or damaged connectors should be replaced. When changing the spark plugs, clean the
terminals and the rubber seals.
