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) maystart 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 should always be completely switched off (in mode 0,
see Ignition modes (p. 74)) 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 touchingany components in the engine compartment. The distributor ignition system operates at very high voltages. Special safety precautionsmust be followed to prevent injury. Alwaysturn the ignition off when:
• Replacing distributor ignition componentse.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintended move-ments and body injury.

CAUTION
•If necessary, top up the cooling system with Volvo Genuine Coolant/Antifreezeonly (a 50/50 mix of water and anti-freeze).
• Different types of antifreeze/coolant maynot be mixed.
• If the cooling system is drained, it shouldbe flushed with clean water or premixedanti-freeze before it is refilled with thecorrect mixture of water/anti-freeze.
• The cooling system must always be keptfilled to the correct level, and the level must be between the
MIN and MAX
marks. If it is not kept filled, there can be high local temperatures in the enginewhich could result in damage. Checkcoolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and has alower boiling point. It can also causedamage to the cooling system if it shouldfreeze.
• 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.
Engine compartment – brake fluid
The brake fluid should always be between the MIN and MAX marks on the inside of the reser-
voir.

Checking the level
The fluid reservoir is concealed under the round cover at the rear of the engine compartment. Theround cover must be removed first before thereservoir cap can be accessed. Check, without removing the cap, that there is sufficient fluid in the reservoir. Fluid type: DOT 4 boiling point >536 °F
(>280 °C).Replace : The fluid should be replaced according
to the intervals specified in the Warranty and Service Records Information booklet. When driving under extremely hard conditions (mountain driving, etc), it may be necessary toreplace the fluid more often. Consult a trainedand qualified Volvo service technician. Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
• If the fluid level is below the
MIN mark in
the reservoir or if a brake-related mes- sage is shown in the information display: DO NOT DRIVE . Have the car towed to a
trained and qualified Volvo service techni- cian and have the brake system inspec-ted.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling
1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the fluid.
The level must be between the MIN and
MAX marks.Engine compartment – power steering fluid
The fluid level must be between the MIN and
MAX marks. For capacities and recommended
fluid grade, see Fuel tank volume – specification and volume (p. 379).
Check the level frequently. It does not normally require changing.
WARNING
If a problem should occur in the power steer- ing system or if the vehicle has no electricalcurrent and must be towed, it is still possibleto steer the vehicle. However, keep in mindthat greater effort will be required to turn thesteering wheel.
