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.

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, haveyour 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.

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.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15
minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.

to index the files on the drive if it contains any-
thing other than compatible music files.
NOTE
•The system supports removable media
that uses the USB 2.0 standard and the
FAT32 file system. It can index up to
1,000 folders and a maximum of 254
sub-folders/files for each folder. How-
ever, the highest folder level can sup-
port up to 1,000 sub-folders/files.
•When using a longer type of USB
device, connecting it with a USB
adapter cable will help reduce mechan-
ical wear on the USB socket and on the
device.
MP3 playerMany MP3 players have a file indexing system
that is not supported by the vehicle's audio
system. In order to use an MP3 player, the sys-
tem must be set to USB Removable device/
Mass Storage Device.
iPodŸ
An iPodŸ receives current and its battery is
charged through the connecting cord. How-
ever, if the iPod's battery is completely
drained, it should be recharged before the
iPodŸ is connected to the audio system.
NOTE
When an iPodŸ is used as a sound source,
the vehicle's audio system has a menu
structure similar to the one in the iPod
Ÿ. See
the iPod's manual for detailed information.
For further information, refer to the accessory
manual USB/iPodŸ Music Interface.
Adjusting volume for an external deviceThe volume of an external device may be dif-
ferent from the volume of the internal sound
sources such as the CD player or the radio. It
the external device's volume is too high, the
quality of the sound may be impaired. To help
prevent this, adjust the external device's input
volume as follows:
1. While playing the radio or a CD, lower the
audio volume to about one-quarter.
2.
Switch to
AUX mode on the audio system
by pressing the MODE button.
3. Connect the headphone output from your
music player to the AUX input using a cable
with a stereo 3.5 mm miniplug at both
ends.
4. Set your music player's headphone vol-
ume to three-quarters using the player's
volume controls.5.
Press MENU on the audio system, and
navigate to
AUX input volume.
6. Turn the volume knob to raise or lower the
AUX input volume until you hear music at
a comfortable level.
7. If there is distortion, lower your music play-
er's headphone volume until the distortion
goes away.
8. Finally, exit the menu and adjust the audio
volume to a comfortable level.
BluetoothŸ streaming audio (BT)The vehicle's audio system is equipped with
BluetoothŸ, which makes it possible to play
streaming audio files from a BluetoothŸ device
such as a cell phone or personal digital assis-
tant (PDA). Navigation and control of the device
can be done through the vehicle's center con-
sole control panel or the steering wheel key-
pad. On certain external devices, it is also pos-
sible to change tracks from the device itself.
In order to listen streaming audio, BT must be
selected as a sound source (see page 245) and
a Bluetooth
Ÿ device must be connected
(paired) with the audio system. See page 263
for more information.
