l Never disconnect the battery when the engine is running (e.g. when repl\
acing the battery).
l Never use a fast charger to charge the battery. The battery cables shoul\
d be disconnected when
recharging.
l The battery contains acid that is both corrosive and poisonous. It is im\
portant that the battery is
handled in an environmentally friendly way. Let your Volvo dealer assist\
you.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the two jack attachments p\
oints should be used. They are
specially reinforced to bear the weight of the vehicle (see the illustr\
ation above). 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 canno\
t slide off it. Always use axle
stands or similar structures. The vehicle's gross vehicle weight is betw\
een 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 illust\
ration).
