Note the following before you begin working
on your vehicle:
Battery
•Ensure that the battery cables are correctly
connected and tightened.
•Never disconnect the battery when the
engine is running (e.g., when replacing the
battery).
•Never use a fast charger to charge the bat-
tery. The battery cables should be discon-
nected when recharging.
•The battery contains acid that is both cor-
rosive and poisonous. It is important that
the battery is handled in an environmen-
tally friendly way. See page 220 for more
information on handling the battery.
Hoisting the vehicle
G027001
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 (see the illustration). A garage
jack can also be placed under the front of the
engine support frame. Take care not to dam-
age the splash guard under the engine. Ensure
that the jack is positioned so that the vehicle
cannot slide off it. Always use axle stands or
similar structures. The vehicle's gross vehicle
weight is between 5770 lbs (2630 kg) and
6080 lbs (2760 kg). Use a jack and stands rated
for this weight.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).
WARNING
The ignition system has very high voltage!
The voltage in the ignition system is dan-
gerous!
Do not touch spark plugs, ignition cables or
the ignition coil when the engine is running
or the ignition is switched on!
The ignition should be switched off when:
•Conducting engine tests.
•Replacing parts in the ignition system,
such as spark plugs, ignition coil, dis-
tributor, ignition cables, etc.
WARNING
Never try to repair any part of the SRS/
SIPS/WHIPS/IC systems yourself. Any
interference in the system could cause mal-
function and serious injury. Any work should
only be performed by an authorized Volvo
workshop.

Battery maintenance
The battery in your vehicle is located under the
floor of the cargo compartment.
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:
•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 15minutes 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.

WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California
to cause cancer and reproductive harm.
Wash hands after handling.
WARNING
•Never expose the battery to open flame
or electric spark.
•Do not smoke near the battery.
•Battery fluid contains sulfuric acid. Do
not allow battery fluid to contact eyes,
skin, fabrics or painted surfaces. If con-
tact occurs, flush the affected area
immediately with water. Obtain medical
help immediately if eyes are affected.
NOTE
Used batteries should be properly disposed
of at a recycling station or similar facility, or
taken to your Volvo retailer.

and screw it securely in place.
NOTE
After the battery has been disconnected or
replaced, lock and unlock the vehicle with
the central locking system's remote key to
reactivate such features as the power win-
dows, moonroof, courtesy lighting, etc.
WARNING
•The battery generates hydrogen gas,
which is flammable and explosive. The
battery is fitted with a ventilation hose
which vents hydrogen gas out of the
battery compartment through a ventila-
tion opening in the bottom of this com-
partment. If the battery must be
replaced, it is essential that the ventila-
tion hose is properly connected to the
battery and that it is routed through the
ventilation opening provided (see illus-
tration).
•Be sure the ventilation hose is free of
debris.
•Only use replacement batteries equip-
ped with a ventilation hose. Consult a
trained and qualified Volvo service tech-
nician.

Introduction
The RSE system can be used at the same time
as the vehicle’s audio system.
When the rear seat passengers play a DVD,
connect an external device to the RSE AUX
connectors, etc., and listen to the audio
through the cordless headphones, the driver
and front seat passenger can still use the vehi-
cle's audio system to listen to the radio, a CD,
music stored on an MP3 player, etc.
Please also refer to the Quick Guide provided
with the RSE system for additional information.
Electrical current - ignition keyThe RSE system can be activated with the igni-
tion in position I or II (see page 141 for infor-
mation on the ignition positions), or when the
engine is running. While the engine is being
started, a film or music that is currently being
played will pause momentarily and resume
playing when the engine has started.
When the RSE system has been used once
when the ignition is switched off, it will be then
be blocked for further use. RSE can be restar-
ted by turning the ignition key to position I.
NOTE

10 minutes with the engine switched off may
drain the vehicle’s battery and make it diffi-
cult or impossible to start the engine.
If this occurs, a message will be displayed
on the RSE system’s screens.
