09 Maintenance and servicing
Maintaining your car09

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 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 cor-
rosion. Corrosion may indicate a loose ter-
minal 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.
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.

09 Maintenance and servicing
Engine oil 09
220
WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces
NOTE
Volvo uses different systems to indicate a
low oil level or pressure. Some models have
an oil pressure sensor, in which case a
warning symbol (see page 60) is used to
indicate low oil pressure. Other models have
an oil level sensor, in which case the driver
is alerted by the warning symbol in the cen-
ter of the instrument panel and a text in the
information display. Some models use both
systems. Contact an authorized Volvo
retailer for more information.

09 Maintenance and servicing
Fluids 09
222
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
G020333
Brake fluid reservoir
The brake fluid should always be between the
MIN and MAX marks on the side of the reser-
voir. 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 accord-
ing 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 serv-
ice technician.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a brake-related
message is shown in the information
display: DO NOT DRIVE. Have the car
towed to a trained and qualified Volvo
service technician and have the brake
system inspected.
•Dot 4+ should never be mixed with any
other type of brake fluid.
Power steering fluid
The fluid level is checked at each service inter-
val.
Fluid type: Volvo power steering fluid or equiv-
alent.
Replace: No fluid change required.
WARNING
If a problem should occur in the power
steering system or if the vehicle has no elec-
trical current and must be towed, it is still
possible to steer the vehicle. However, keep
in mind that greater effort will be required to
turn the steering wheel.
