Owner maintenancePeriodic 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.Emission inspection readinessWhat 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.

09 Maintenance and servicing
Battery
09``221 Battery maintenance
Driving habits and conditions, climate, the
number of starts, etc., all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
Check the fluid level in each cell in the battery
every 24 months or every 15,000
1 miles
(24,000 km), whichever is sooner.
•
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.
•
Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•
The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
