2008 VOLVO S40 Owners Manual

206 09 Maintenance and servicing
Fluids
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces
NOTE
Volvo uses different systems to indicate a low oil level or pressure. Some models have an oil pressure sensor, in
which case a warning symbol (see page 54
) is used to indicate low oil pressure. Other models have an oil level
sensor, in which case the driver is alerted by the warning symbol in the center of the instrument panel and a text in
the information display. Some models use both systems. Contact an authorized Volvo retailer for more information.
Washer fluid
The washer fluid reservoir is located in the engine compartment and holds approximately 6.8 US qts (6.5 liters).
During cold weather, the reservoir should be filled with windshield washer solvent containing antifreeze.
Coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified
ProCarManuals.com

Volvo service technician.
NOTE
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
207 09 Maintenance and servicing
Fluids
CAUTION
The cooling system must always be kept filled 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 engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly!
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools. If it is necessary to top off the
coolant when the engine is warm, unscrew the expansion tank cap slowly so that the overpressure dissipates.
Brake fluid
The brake fluid should always be between the MIN and MAX marks on the side of the reservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type: DOT 4+ boiling point >536°F (280°C), P/N 9437433
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 to
replace the fluid more often. Consult your Volvo retailer. Always entrust brake fluid changing to a trained and
qualified Volvo service technician.
Power steering fluid
The fluid level is checked at each service interval.
ProCarManuals.com

Fluid type: Volvo power steering fluid or equivalent.
Replace: No fluid change required.
WARNING
If a problem should occur in the power steering system or if the vehicle has no electrical current and must be towed,
it is still possible to steer the vehicle. However, keep in mind that greater effort will be required to turn the steering
wheel.

NOTE
The wiper blades are different lengths. The blade on the driver's side is longer than the one on the passenger's side.
Keeping the windshield and wiper blades clean helps improve visibility and prolongs the service life of the wiper
blades. See page 192
for washing instructions.

Battery
Battery maintenance
ProCarManuals.com

Driving habits and conditions, climate, the number of starts, etc., all affect the service life and function of the battery.
In order for your battery to perform satisfactorily, keep the following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,0001 miles (24,000 km), whichever is
sooner. The fluid should be at the level shown in the illustrations above (A). Do not overfill.
1More frequently in warm climates.
Use a screw driver to open the caps or cover and a flashlight to inspect the level.
If necessary, add distilled water. The level should never be above the indicator (A).
The fluid level should be checked if the battery has been recharged.
After inspection, be sure the cap over each battery cell or the cover is securely in place.
Check that the battery cables are correctly connected and properly tightened.
Never disconnect the battery when the engine is running, or when the key is in the ignition. This could damage the
vehicle's electrical system.
The battery should be disconnected from the vehicle when a battery charger is used directly on the battery.
WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of
California to cause cancer and reproductive harm. Wash hands after handling.

Replacing bulbs
Introduction
Before replacing bulbs in your vehicle, please keep the following points in mind:
NOTE
Never touch the glass of bulbs with your fingers. Grease and oils from your fingers vaporize in the heat and will
leave a deposit on the reflector, which will damage it.
The optional Bi -Xenon® headlight bulbs contain trace amounts of mercury. These bulbs should always be
disposed of by an authorized Volvo retailer.
Certain bulbs should only be replaced by a trained and qualified Volvo service technician:
- Courtesy (dome) lighting
- Reading lights
- Glove compartment lights
- Turn signals and courtesy lights in the side door mirrors
- High-mounted brake lights
