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.

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.

Handling
• Check that the battery cables are correctly connected and tightened.
• Never disconnect the battery when theengine is running (for example, when replac-ing the battery).
• If the battery is fully discharged a number oftimes, this may shorten its service life.
• The service life of a battery is affected byfactors such as the number of starts, drivingconditions and climate. Extreme cold mayalso further decrease the battery

Proper battery maintenance can help prolong its service life.
Maintenance
• Use a screw driver to open the caps or cover and a flashlight to inspect the level.
• If necessary, add distilled water. The levelshould never be above the indicator.
• The fluid level should be checked if the bat-tery has been recharged.
• After inspection, be sure the cap over eachbattery cell or the cover is securely in place.
• Check that the battery cables are correctlyconnected and properly tightened.
• Never disconnect the battery when theengine is running, or when the key is in theignition. This could damage the vehicle'selectrical system.
• The battery should be disconnected from thevehicle when a battery charger is useddirectly on the battery.
• To help keep the battery in good condition,the vehicle should be driven for at least 15minutes a week or connected to a chargerwith an automatic charging function.
• If the battery is fully discharged a number oftimes, this may shorten its service life. Keep-ing the battery fully charged helps prolong itsservice life. •
