check oil VOLVO S40 2008 User Guide

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 fluid levels are between the indicated "min" and "max" markings.
Clean interior glass surfaces with a glass cleaner and soft paper towels.
Wipe driver information displays with a soft cloth.
Visually inspect battery terminals for corrosion. Corrosion may indicate a loose terminal connector, or a battery near
the end of its useful service life. Consult a trained and qualified Volvo service technician 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 by salt residues.
Clean leaves and twigs from air intake vents at the base of the windshield, and from other places where they may
collect.

Maintaining your car
Emission inspection readiness
What is an Onboard Diagnostic System (OBD II)?
OBD II is part of your vehicle's computerized engine management system. It stores diagnostic information about your
vehicle's emission controls. It can light the Check Engine light (MIL) if it detects an emission control "fault." A "fault"
is a component or system that is not performing within an expected range. A fault may be permanent or temporary.
OBD II will store a message about any fault.
How Do States Use OBD II for Emission Inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can then read "faults." In some
states, this type of inspection has replaced the tailpipe emission test.
How Can My Vehicle Fail OBD II Emission Inspection ?
Your vehicle can fail OBD II emission inspection for any of the following reasons.
If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit, but went out without any action on your part, OBD II will still have a
recorded fault. Your vehicle may pass or fail, depending on the inspection practices in your area.
If you had recent service that required disconnecting the battery, OBD II diagnostic information may be incomplete
and "not ready" for inspection. A vehicle that is not ready may fail inspection.

Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and
at additional charge. Please consult a trained and qualified Volvo service technician.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service
The car should be parked on a level surface when the oil is checked.
If the engine is warm , wait for at least 10-15 minutes after the engine has been switched off before checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck the oil level. If necessary, add oil until the
level is near the MAX mark.
NOTE
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.
Always add oil of the same type and viscosity as already used.
Never fill oil above the MAX mark. This could cause an increase in oil consumption.

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).

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.
