WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
WARNING
The ignition should always be completely switched off before performing any operations in the engine compartment.
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.
212 06 Maintenance and specifications
Engine oil
Checking the engine oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service.
See page 272 for oil specifications.
Refer to the Warranty and Service Records Information booklet for information on the oil change intervals.
Volvo recommends Castrol.
CAUTION
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.

The windshield and headlight washers share a common reservoir.
The washer fluid reservoir is located on the driver's side of the engine compartment. During cold weather, the reservoir
should be filled with windshield washer solvent containing antifreeze. For capacities, see page 275

Wheels and tires
Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off. Ensure that the on/off switch is in position 0 (the 0 side of the switch should
be pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
6. Start the vehicle's engine.
WARNING
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be
sure the vehicle is parked in a well ventilated place, or outdoors, before using the system.
Children should never be left unattended in the vehicle when the engine is running.
7. Check the tire's inflation pressure on the gauge. Switch off the compressor briefly to get a clear reading from the
pressure gauge.
8. Refer to the tables on pages 240 and 241
for the correct tire inflation pressure. If the tire needs to be inflated, start
the tire sealing system's compressor (press the on/off switch to position I ). If necessary, release air from the tire by
turning the air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct inflation pressure has been reached.
10. Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
11. Disconnect the electrical wire from the 12-volt socket.

Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
5. Unscrew the orange cover over the bottle holder and unscrew the cap on the bottle of sealing compound.
NOTE
Do not break the seal on the bottle. This occurs automatically when the bottle is screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help prevent sealing compound leakage. Once in
place, the bottle cannot be unscrewed. This must be done by a trained and qualified Volvo service technician.
7. Remove the valve cap from the tire's inflation valve and screw the tire sealing system's hose connector onto the
valve as tightly as possible by hand.

the vehicle is parked in a well ventilated place, or outdoors, before using the system.
10. Start the tire sealing system's compressor by pressing the on/off switch to position I .
WARNING
Never stand next to the tire being inflated when the compressor is in operation.
If cracks, bubbles, etc. form on the tire, switch off the compressor immediately.
If there is visible damage to the sidewall or the rim, the tire cannot be repaired. The vehicle should not be driven if
this occurs. Contact a towing service or Volvo On Call Roadside Assistance if applicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approximately 88 psi (6 bar) while the
sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately 30
seconds.
11. Within seven minutes, inflate the tire to between 22-44 psi (1.8-3.0 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge.
