Maintaining your vehicle09

203 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 vehicle 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 a trained
and qualified Volvo service technician for
additional information.
As needed
•Wash the vehicle, including the undercar-
riage, 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.
•Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvote-
chinfo.com.
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 ofinspection 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-

Engine oil09

209
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 56) 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 a trained and qualified
Volvo service technician for more informa-
tion.
Changing engine oil and oil filter
See page 208 for oil specifications and page
273 for oil volumes. Refer to the Warranty and
Service Records Information booklet for infor-
mation on the oil change intervals.
NOTE
Volvo does not recommend the use of oil
additives.
Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge. Please consult a trained and
qualified Volvo service technician.
Checking and adding oil
G030880
Location of dipstick (1) and oil filler cap (2)
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 vehicle 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
•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 approximately
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.
•Oil level should be between the MIN and
MAX marks on the dipstick.

09 Maintenance and servicing
Fluids 09
212
WARNING
•Never remove the radiator cap while the
engine is warm. Wait until the vehicle
cools.
•If it is necessary to top up the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid reservoir
G000000
The brake fluid should always be above the
MIN mark on the side of the reservoir. Check,
without removing the cap, that there is suffi-
cient fluid in the reservoir.Fluid type: DOT 4+ boiling point >536 °F
(280 °C), P/N 9437433.
Replace: Every second year or 30,000 miles
(48,000 km). The fluid should be replaced once
a year or every 15,000 miles (24,000 km) when
driving under extremely hard conditions
(mountain driving, etc.).
Always entrust brake fluid changing to a
trained and qualified Volvo service 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 reservoir
FULL
ADD
G026991
The fluid level should always be between the
ADD and FULL marks.
Fluid type: Volvo synthetic power steering fluid
(Pentosin CHF 11S) P/N 1161529 or equiva-
lent.
Replace: No fluid change required.
If a problem should occur in the power steering
system or if the vehicle has no electrical 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.
