* Option/accessory, for more information, see Introduction.145 Starting a vehicle with keyless drive
G019410
Keyless drive makes it possible to unlock, start
and lock the vehicle without using a remote
key.
A start control is fitted in the ignition switch on
vehicles equipped with the optional keyless
drive. This control is used in the same way as
the ignition key to start the engine. See also
page 143 for general information on starting
the engine.
NOTE
A keyless drive remote key must be inside
the vehicle in order to start the engine.
1. Press the brake pedal (the clutch pedal
must also be fully depressed on models
with a manual transmission).
2. Press in the keyless drive start control and
turn it to position III.
NOTE
The vehicle is equipped with an autostart
function that makes it possible to start the
engine without holding the start control in
position III. Turn the start control to posi-
tion III and release it. The starter motor will
then operate automatically (for up to ten
seconds) until the engine starts.
Starting the vehicle with the ignition key
(remote key)
A vehicle with keyless drive can also be started
with the ignition key (if, for example, the battery
in the keyless drive remote key is weak). To do
so:
G019420
Removing the keyless drive start control
Press the catch on the side of the start con-
trol (see the illustration).
Pull the keyless drive start control out of the
ignition switch.
Insert the remote key into the ignition switch
and turn it to position III to start the engine,
page 143 for complete starting information.

WARNING
Towing a vehicle with a locked steering
wheel will make the vehicle impossible to
steer.
2. Insert the key into the ignition to unlock the
steering wheel. The steering wheel must be
unlocked. With the engine off and the vehi-
cle at a standstill, great effort will be
required to turn the steering wheel.
3.
Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehi-
cles with automatic transmissions, follow
instruction on page 149, "Shiftlock over-
ride" to allow the gear selector to be moved
from the Park position.
5. Keep firm pressure on the brake pedal
while releasing the parking brake.
6. When towing has been completed, return
the gear selector to Park (automatic) or
Reverse (manual) and apply the parking
brake.
The following points should also be
observed:
•Never exceed 50 mph (80 km/h). Never
exceed local towing speed limits and heed
all local towing restrictions.
•Never tow farther than 50 miles (80 km).
•Keep the tow rope taut at all times while the
vehicle is in motion.
•The disabled vehicle should be towed in
the forward direction only.
WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 157 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.

09 Maintenance and servicing

219 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.

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
