The appearance of the engine compartment may vary depending on engine model.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator)may start or continue to operate (for up to6 minutes) after the engine has beenswitched off.
WARNING
Before performing any operations in the engine compartment, the ignition shouldalways be completely switched off (inmode 0, see page 87) and there should be
no remote keys in the passenger compart-ment. The gear selector should be in the P
(park) position. If the engine has been run-ning, wait until it has cooled before touch-ing any components in the engine com-partment. The distributor ignition system operates at very high voltages. Special safety precau-tions must be followed to prevent injury.Always turn the ignition off when:
• Replacing distributor ignition compo- nents e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintendedmovements and body injury.

Checking the engine oil
The oil level should be checked at regular intervals, particularly during the period up tothe first scheduled maintenance service.• See page 375 for oil specifications.
• Also, refer to the Warranty and Service Records information booklet for informa-tion on oil change intervals and oil speci-fications.
CAUTION
•Not checking the oil level regularly can result in serious engine damage if theoil level becomes too low.
• Oil that is lower than the specifiedquality can damage the engine.
• Volvo does not recommend the use ofoil additives.
• Always add oil of the same type andviscosity as already used.
• Never fill oil above the
MAX mark. This
could cause an increase in oil con-sumption.
• Oil changes should be carried out by atrained and qualified Volvo servicetechnician.
Checking and adding oil
G021734
Location of the filler cap and dipstick
Volvo recommends Castrol oil products
NOTE
Before checking the oil: •The car should be parked on a level surface.
• If the engine is warm
, wait for at least
10 – 15 minutes after the engine hasbeen switched off.
G021737
The oil level must be between the MIN and MAX
marks on the dipstick
Checking the oil1. Pull out the dipstick and wipe it with a
lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level. The level must be between the MIN and MAX marks.

3. Add oil if necessary. If the level is close to
the MIN mark, add approximately
0.5 US quarts (0.5 liters) of oil.
4. Recheck the level and add more oil if necessary until the level is near the MAX
mark.
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.

Fluids 09
338
Coolant
Location of the coolant reservoir
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. See page 376 for information on cooling sys- tem capacities.
CAUTION
• If necessary, top up the cooling sys- tem with Volvo Genuine Coolant/Anti-freeze only (a 50/50 mix of water andantifreeze).
• Different types of antifreeze/coolantmay not be mixed.
• If the cooling system is drained, itshould be flushed with clean water orpremixed anti-freeze before it is refilledwith the correct mixture of water/anti-freeze.
• The cooling system must always bekept filled to the correct level, and thelevel must be between the
MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in theengine which could result in damage.Check coolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and hasa lower boiling point. It can also causedamage to the cooling system if itshould freeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
WARNING
• Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
Brake fluid
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the round cover at the rear of the engine com-partment. The round cover must be removedfirst before the reservoir cap can beaccessed.

Risk of explosion
Recycle properly
NOTE
A used battery should be disposed of in an environmentally responsible manner. Con-sult your Volvo retailer or take the batteryto a recycling station.
Handling
•Check that the battery cables are cor- rectly connected and tightened.
• Never disconnect the battery when theengine is running (for example, whenreplacing the battery).
• If the battery is fully discharged a numberof times, this may shorten its service life.
• The service life of a battery is affected byfactors such as the number of starts, driv-ing conditions and climate. Extreme cold may also further decrease the battery’sstarting capacity.
• Because the battery’s starting capacitydecreases with time, it may be necessaryto recharge it if the vehicle is not drivenfor an extended period of time or if thevehicle is usually only driven short dis-tances.
• Never use a quick charger to charge thebattery.
CAUTION
The infotainment system's energy-saving feature may not function correctly or at all,and/or a message may be displayed if abattery charger or jumper cables are notconnected properly.
• The negative terminal on the battery must
never be used to connect a
jumper cable or a battery charger.Only the ground point on the chassismay be used.
