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.
How can I prepare for my next OBD II emission inspection?
If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if
necessary, serviced by a qualified Volvo technician.
If you recently had service for a lit Check Engine light, or if you had service that required disconnecting the battery,
a period of driving is necessary to bring the OBD II system to "ready" for inspection. A half-hour trip of mixed stop-
and -go/ highway driving is typically needed to allow OBD II to reach readiness. Your Volvo retailer can provide you
with more information on planning a trip.
Maintain your vehicle in accordance with your vehicle's maintenance schedule.

Changing engine oil and oil filter
See page 191
for oil specifications. Refer to the Warranty and Service Records Information booklet for information on
the oil change intervals.
Volvo recommends
.
NOTE:
Volvo does not recommend the use of oil additives.
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 your Volvo retailer.
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.
CAUTION!
ProCarManuals.com

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.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.

Fluids
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 your Volvo retailer.
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).
CAUTION!
ProCarManuals.com

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.
pg. 160 Maintenance and servicing
Fluids
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 should always be between the MIN and MAX marks.

Battery
Battery maintenance
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 illustration above (A). Do not overfill.
Use a screw driver to open the caps 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 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.
