Maintenance – owner maintenance
Periodic maintenance requirements and inter- vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Owner maintenance
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min"and "max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with asoft cloth.
• Visually inspect battery terminals for cor-rosion. Corrosion may indicate a looseterminal connector, or a battery near theend of its useful service life. Consult yourVolvo retailer for additional information.
As needed:Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup of dirt, and corrosion that can be caused bysalt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from otherplaces where they may collect.

there should be no remote keys in the pas-senger compartment. The gear selectorshould be in the P (park) position. If the
engine has been running, wait until it hascooled before touching any components inthe engine compartment. 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 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. 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 Informationbooklet. When driving under extremely hard condi- tions (mountain driving, etc), it may be neces-sary to replace the fluid more often. Consult atrained and 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 message is shown in the informationdisplay: DO NOT DRIVE . Have the car
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling1. 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 recom-
mended fluid grade, see Fuel tank volume – specification and volume (p. 362).
Check the level frequently. It does not nor- mally require changing.
WARNING
If a problem should occur in the power steering system or if the vehicle has noelectrical current and must be towed, it isstill possible to steer the vehicle. However,keep in mind that greater effort will berequired to turn the steering wheel.
