Working On Your Vehicle - Volvo XC90 Owner's Manual

Note the following before you begin work-
ing on your vehicle:
Battery
•
Ensure that the battery cables are cor-
rectly 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
battery. The battery cables should be dis-
connected 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 227 for more
information on handling the battery.
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 (see the illustration). 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 positioned so
that the vehicle cannot slide off it. Always use
axle stands or similar structures. The vehi-
cle's gross vehicle weight is between
5770 lbs (2630 kg) and 6080 lbs (2760 kg).
Use a jack and stands rated for this weight.
09 Maintenance and servicing

Working on your vehicle

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 illustra-
tion).

The voltage in the ignition system is dan-
gerous!
Do not touch spark plugs, ignition cables

ning or the ignition is switched on!
The ignition should be switched off when:
