257 Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.
Each time the car is refueled:
•Check the engine oil level.
•Clean the windshield, windshield wipers,
headlights, and tail lights.
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 cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult your Volvo
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 by salt
residues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other pla-
ces where they may collect.
NOTE
Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the
two jack attachments points should be used.They are specially reinforced to bear the weight
of the vehicle. A garage jack can also be placed
under the front of the engine support frame.
Take care not to damage the splash guard
under the engine. Ensure that the jack is posi-
tioned so that the vehicle cannot slide off it.
Always use axle stands or similar structures.
If a two-post hoist is used to lift the vehicle, the
front and rear lift arm pads should be centered
under the reinforced lift plates on the inboard
edge of the sill rail (see illustration).
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 diagnos-
tic 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 inspec-
tion 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 dis-
connecting 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/high-way driving is typically needed to allow
OBD II to reach readiness. Your Volvo
retailer can provide you with more infor-
mation on planning a trip.
•Maintain your vehicle in accordance with
your vehicle's maintenance schedule.

WARNING
The ignition should always be completely
switched off before performing any opera-
tions in the 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 distributor
ignition system while the engine is run-
ning. This may result in unintended
movements and body injury.

07 Maintenance and specifications
Engine oil
07
260
Checking the engine oil
The oil level should be checked at regular inter-
vals, particularly during the period up to the
first scheduled maintenance service.
•See page 298 for oil specifications.
•Refer to the Warranty and Service Records
Information booklet for information on the
oil change intervals.
Volvo recommends Castrol oil products.
CAUTION
•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 qual-
ity can damage the engine.
•Volvo does not recommend the use of
oil additives.
•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 consump-
tion.
Checking and adding oil
G021734
Location of the filler cap and dipstick
NOTE
Before checking the oil:
•The car should be parked on a level sur-
face.
•If the engine is warm, wait for at least
10 – 15 minutes after the engine has
been switched off.
G021737
The oil level must be between the MIN and MAX
marks on the dipstick
Checking the oil1. Pull out the dipstick and wipe it with a lint-
free rag.
2. Reinsert the dipstick, pull it out, and check
the oil level. The level must be between the
MIN and MAX marks.
3. Add oil if necessary. If the level is close to
the MIN mark, add approximately
0.5 US quarts (0.5 liters) of oil.
4. Recheck the level and add more oil if nec-
essary until the level is near the MAX mark.

07 Maintenance and specifications
Fluids
07
262
Coolant
Location of the coolant reservoir
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
See page 299 for information on cooling sys-
tem capacities.
CAUTION
•If necessary, top up the cooling system
with Volvo Genuine Coolant/Antifreeze
only (a 50/50 mix of water and anti-
freeze).
•Different types of antifreeze/coolant
may not be mixed.
•If the cooling system is drained, it
should be flushed with clean water or
premixed anti-freeze before it is refilled
with the correct mixture of water/anti-
freeze.
•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.
Check coolant regularly!
•Do not top up with water only. This
reduces the rust-protective and anti-
freeze qualities of the coolant and has a
lower boiling point. It can also cause
damage to the cooling system if it
should freeze.
•Do not use chlorinated tap water in the
vehicle's cooling system.
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
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the
round cover at the rear of the engine compart-
ment. The round cover must be removed first
before the reservoir cap can be accessed.

Keep away from children.
Avoid smoking, open flames,
and/or sparks.
See the owner's manual.
Contains corrosive acid.
Risk of explosion
NOTE
A used battery should be disposed of in an
environmentally responsible manner. Con-
sult your Volvo retailer or take the battery to
a recycling station.
Handling
•Check that the battery cables are correctly
connected and tightened.
•Never disconnect the battery when the
engine is running (for example, when
replacing the battery).
•If the battery is fully discharged a number
of times, this may shorten its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
Never use a quick charger to charge the bat-
tery.
WARNING
•Never expose the battery to open flame
or electric spark.
•Do not smoke near the battery.
•Battery fluid contains sulfuric acid. Do
not allow battery fluid to contact eyes,
skin, fabrics or painted surfaces. If con-
tact occurs, flush the affected area
immediately with water. Obtain medical
help immediately if eyes are affected.
NOTE
The life of the battery is shortened if it
becomes discharged repeatedly.
Maintenance
•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.
•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.
