The fuel filler door is located on the right rear
fender (indicated by an arrow beside the fuel
tank symbol on the information display
)
With the ignition switched off, press the button
on the lighting panel to unlock the fuel filler
door. Please note that the fuel filler door will
remain unlocked until the vehicle begins to
move forward. An audible click will be heard
when the fuel filler door relocks.
•If you intend to leave your vehicle while it
is being refueled, this feature enables you
to lock the doors/tailgate while leaving the
fuel filler door unlocked.
•You can also keep the vehicle locked if you
remain inside it during refueling. The cen-
tral locking button does not lock the fuel
filler door.
•Be sure the fuel filler door is not obstructed
and is completely closed after refueling.
•Open the fuel filler cap slowly during hot
weather.
Close the fuel filler door by pressing it a click
indicates that it is closed.
CAUTION
•Avoid spilling gasoline during refueling.
In addition to causing damage to the
environment, gasolines containing
alcohol can cause damage to painted
surfaces, which may not be covered
under the New Vehicle Limited War-
ranty.
Manually opening the fuel filler door
If necessary, the fuel filler door can be opened
manually:
1. Open the side hatch in the cargo compart-
ment (on the same side as the fuel filler
door).

CAUTION
•Do not refuel with the engine running1.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
•Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much fuel
in the tank in hot weather conditions can
cause the fuel to overflow. Overfilling
could also cause damage to the emis-
sion control systems.
Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will helpavoid malfunctions that could damage the
three-way catalytic converter.
•Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
•Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•Remember that tampering or unauthorized
modifications to the engine, the Engine
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location or removing com-
ponents, and/or repeated use of leaded
fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's
performance will not be affected. Use only Volvo original or approved fuel filler caps.

Roof loads
Using load carriersLoad carriers are available as Volvo accesso-
ries. Observe the following points when in use:
•To avoid damaging your vehicle and to
achieve maximum safety when driving, we
recommend using the load carriers that
Volvo has developed especially for your
vehicle.
•Volvo-approved removable roof racks are
designed to carry the maximum allowable
roof load for this vehicle: 220 lbs (100 kg).
For non-Volvo roof racks, check the man-
ufacturer's weight limits for the rack.
•Never exceed the rack manufacturer's
weigh limits and never exceed the maxi-
mum rated roof load of 220 lbs (100 kg).
•Avoid single-point loads. Distribute loads
evenly.
•Place heavier cargo at the bottom of the
load.
•Secure the cargo correctly with appropri-
ate tie-down equipment.
•Check periodically that the load carriers
and load are properly secured.
•Remember that the vehicle's center of
gravity and handling change when you
carry a load on the roof.
•The vehicle's wind resistance and fuel con-
sumption will increase with the size of the
load.
•Drive smoothly. Avoid rapid starts, fast
cornering and hard braking.

215 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

Checking the engine 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.
•See page 276 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

Location of the filler cap and dipstick
NOTE
Before checking the oil:
•The car should be parked on a level sur-
face 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.
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.

Wheels and tires

Introduction
Your vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening), or on the inside of the fuel filler door
on Canadian models.
CAUTION
Some Volvo models are equipped with an
Ultra High Performance tire and wheel com-
bination designed to provide maximum dry
pavement performance with consideration
for hydroplaning resistance. As such, they
may be more susceptible to road hazard
damage and, depending on driving condi-
tions, may achieve a tread life of less than
20,000 miles (30,000 km). Even if this vehi-
cle is equipped with Volvo’s advanced AWD
or DSTC system, these tires are not
designed for winter driving, and should be
replaced with winter tires when weather
conditions dictate.
The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.
Certain models are equipped with "all-season"
tires, which provide a somewhat higher degreeof road holding on slippery surfaces than tires
without the "all-season" rating. However, for
optimum road holding on icy or snow-covered
roads, we recommend suitable winter tires on
all four wheels.
When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's roadholding and handling characte-
ristics.
New Tires
Remember that tires are perishable goods. As
of 2000, the manufacturing week and year
(Department of Transportation (DOT) stamp)
will be indicated with 4 digits (e.g. 1502 means
that the tire illustrated was manufactured dur-
ing week 15 of 2002).
G021823
Tire ageTires degrade over time, even when they are
not being used. It is recommended that tires
generally be replaced after 6 years of normal
service. Heat caused by hot climates, frequent
high loading conditions or Ultra Violet (U.V)
exposure can accelerate the aging process.
You should replace the spare tire when you
replace the other road tires due to the aging of
the spare.
A tire's age can be determined by the DOT
stamp on the sidewall (see the illustration).
A tire with e.g., visible cracks or discoloration
should be replaced immediately.
Improving tire economy
•Maintain correct tire pressure. For the tire
pressure tables, see pages 247 and 247.
•Drive smoothly: avoid fast starts, hard
braking and tire screeching.
•Tire wear increases with speed.
•Correct front wheel alignment is very
important.
•Unbalanced wheels impair tire economy
and driving comfort.
•Tires must maintain the same direction of
rotation throughout their lifetime.
•When replacing tires, the tires with the
most tread should be mounted on the rear
