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 oil09
215
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 53) 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
Fluids09
217
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.

AUXThe AUX (auxiliary) port, located under the cen-
ter armrest, can be used to connect for exam-
ple, an MP3 player.
If the player is being charged through a 12-volt
socket while it is connect to the AUX port,
sound quality may be impaired.
The volume of the external sound source AUX
may be different from the volume of the internal
sound sources such as the CD player or the
radio. If the external sound source's volume is
too high, the quality of the sound may be
impaired.
This can be prevented by adjusting the external
sound source's input volume.

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

player or a USB flash drive can be connected
to the audio system via the connector in the
center console storage compartment. A stand-
ard cable from an iPodŸ or MP3 player can be
routed under the cover to the AUX connector
in the storage compartment.
A sound source must be chosen, depending on
the device that has been connected:

The text LOADING will be displayed while the
system loads the files (folder structure) on the
device. This may take a short time.
When information about the files (the folder
structure) on the device has been loaded, the
resulting list includes information on the artist,
genre and song title.
To navigate in the folder structure, press
ENTER and scroll up and down the folders
using the arrow buttons (on the audio system
control panel or on the steering wheel keypad).
Press the right arrow button to select a folder.
Press the left arrow button to go up a level in
the folder structure. Press ENTER to go down
a level in the folder structure.
Tracks can be selected in two ways:

Turn the Tuning knob (no. 4 in the illustra-
tion on page 243) clockwise or counter-
clockwise.

Use the right or left arrow keys on the nav-
igation control (no. 5 in the illustration on
page 243) to select the desired track. The
arrow keys on the steering wheel keypad
can also be used in the same way.NOTE
The system supports playback of files in the
most common versions of formats such as
mp3, wma, and wav. However, there may be
versions of these formats that the system
does not support.
The system also supports a number of
iPodŸ models produced in 2005 or later.
iPodŸ Shuffle is not supported.
USB flash driveTo simplify the use of a USB flash drive, it is
advisable to only store music files on the drive.
It will take considerably longer for the system
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 and can index up to 500 folders
and a maximum of 64,000 files. The device
must have at least 256 Mb of memory.
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 iPodŸ. See
the iPod's manual for detailed information.
For further information, refer to the accessory
manual USB/iPodŸ Music Interface.
Sound settings
Optimal sound reproductionThe audio system is calibrated for optimal
sound reproduction through the use of digital
signal processing. This calibration takes into
account the speakers, amplifier, cabin acous-
tics, the seating position of the listener, etc., for
each combination of vehicle and audio system.
There is also dynamic calibration that takes
into account the setting of the volume control,
radio reception, and the vehicle's speed. The
sound settings described in this manual, such
as
BASS, TREBLE, and EQUALIZER are only
