Maintaining your car
Owner maintenance
Periodic maintenance requirements and intervals are described in your ve\
hicle's Warranty and Service
Records Information booklet.
The following points can be carried out between the normally scheduled m\
aintenance services.
Each time the vehicle is refueled:
l Check the engine oil level
l Clean the windshield, windshield wipers, headlights, and tail lights
Monthly:
l Check cold tire pressure in all tires. Inspect the tires for wear.
l Check that engine coolant and other fluid levels are between the indicat\
ed "min" and "max" markings.
l Clean interior glass surfaces with a glass cleaner and soft paper towels\
.
l Wipe driver information displays with a soft cloth.
l 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 your Volvo re\
tailer for additional information.
As needed:
l Wash the vehicle, including the undercarriage, to reduce wear that can b\
e caused by a buildup of dirt,
and corrosion that can be caused by salt residues.
l Clean leaves and twigs from air intake vents at the base of the windshie\
ld, and from other places
where they may collect.

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 Che\
ck 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 messag\
e 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. Th\
e inspector can then read
"faults." In some states, this type of inspection has replaced the tailp\
ipe emission test.
How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspection for any of the followin\
g reasons.
l If your Check Engine (MIL) light is lit, your vehicle may fail inspect\
ion.
l If your vehicle's Check Engine light was lit, but went out without any a\
ction 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.
l If you had recent service that required disconnecting the battery, OBD I\
I diagnostic information may
be incomplete and "not ready" for inspection. A vehicle that is not read\
y may fail inspection.
How can I prepare for my next OBD II emission inspection?
l If your Check Engine (MIL) light is lit - or was lit but went out with\
out service, have your vehicle
diagnosed and, if necessary, serviced by a qualified Volvo technician.
l 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 ty\
pically needed to allow OBD II
to reach readiness. Your Volvo retailer can provide you with more inform\
ation on planning a trip.
l Maintain your vehicle in accordance with your vehicle's maintenance sche\
dule.

l Never disconnect the battery when the engine is running (e.g. when repl\
acing the battery).
l Never use a fast charger to charge the battery. The battery cables shoul\
d be disconnected when
recharging.
l The battery contains acid that is both corrosive and poisonous. It is im\
portant that the battery is
handled in an environmentally friendly way. Let your Volvo dealer assist\
you.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the two jack attachments p\
oints should be used. They are
specially reinforced to bear the weight of the vehicle (see the illustr\
ation above). 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 positioned so that the vehicle canno\
t slide off it. Always use axle
stands or similar structures. The vehicle's gross vehicle weight is betw\
een 5770 lbs (2630 kg) and 6080
lbs (2760 kg). Use a jack and stands rated for this weight.
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 illust\
ration).
pg. 184 Maintenance
Working on your vehicle
WARNING!
The ignition system has very high voltage! The voltage in the ignition s\
ystem is dangerous!
Do not touch spark plugs, ignition cables or the ignition coil when the \
engine is running or the
ignition is switched on!
The ignition should be switched off when:
l Conducting engine tests.
l Replacing parts in the ignition system, such as spark plugs, ignition co\
il, distributor, ignition
cables, etc.
WARNING!
Never try to repair any part of the SRS/ SIPS/WHIPS/IC systems yourself. Any \
interference in the
system could cause malfunction and serious injury. Any work should only \
be performed by an
authorized Volvo workshop.

Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and require\
s no adjustment
between changes.
WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "\
MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the eng\
ine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
Changing 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 an\
tifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/ 50 mix of wat\
er and antifreeze). CAUTION!
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
l The upper section describes the oil's performance level.
l The center identifies the oil's viscosity.
l The lower section indicates whether the oil has demonstrated energy-cons\
erving properties in a
standard test in comparison to a reference oil.

Engine oil
Changing engine oil and oil filter
See the previous page for oil specifications and
page 212 for oil volumes. Refer to the Warranty and
Service Records Information booklet for information on the oil change in\
tervals.
NOTE:
l Volvo does not recommend the use of oil additives.
l Synthetic oil is not used when the oil is changed at the normal maintena\
nce 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.
l The vehicle should be parked on a level surface when the oil is checked.\

l 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
- Pull out the dipstick and wipe it with a lint-free rag.
- Reinsert the dipstick, pull it out, and check the oil level.
- Add oil if necessary. If the level is close to the MIN mark, add appro\
ximately 1 US quart (1 liter) of oil.
- Run the engine until it reaches normal operating temperature.
- 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 mark.
CAUTION!
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Never fill oil above the MAX mark. This could cause an increase in oil\
consumption.
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Always add oil of the same type and viscosity as already used.

Battery maintenance
The battery in your vehicle is located under the floor of the cargo comp\
artment.
Driving habits and conditions, climate, the number of starts, etc. all a\
ffect the service life and function of
the battery. In order for your battery to perform satisfactorily, keep t\
he following in mind:
l Check the fluid level in each cell in the battery every 24 months or eve\
ry 15,0001 miles (24,000 km),
whichever is sooner. The fluid should be at the level shown in the illus\
tration above (A)
2. Do not
overfill.
l Use a screw driver to open the caps or cover and a flashlight to inspect\
the level.
l If necessary, add distilled water. The level should never be above the i\
ndicator (A)2.
l The fluid level should be checked if the battery has been recharged.
l After inspection, be sure the cap over each battery cell or cover is sec\
urely in place.
l Check that the battery cables are correctly connected and properly tight\
ened. Route ventilation hose
through opening in floor (see
page 192)
l Never disconnect the battery when the engine is running, for example whe\
n changing the battery.
l The battery should be disconnected from the vehicle when a battery charg\
er is used directly on the
battery.
