11. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the connections between
cable and car during the starting attempt.
There is a risk of sparks forming.
12. Remove the jump leads in reverse order -
first the black and then the red.
Make sure that none of the black jump
lead's clamps comes into contact with the
car's positive jump-starting point/donor
battery's positive terminal or the clamp
connected to the red jump lead.
WARNING
High voltage can be dangerous in the event
of incorrect intervention. Do not touch any-
thing on the batteries that is not clearly
described in the owner's manual.
48 V support battery must never be
•
used for jump-starting.
External electrical equipment must not
•
be connected to the 48 V battery
under any circumstances.
The 48 V battery may only be serviced
•
and replaced by a workshop – an
authorised Volvo workshop is recom-
mended.
STARTING AND DRIVING
WARNING
The battery can generate oxyhydrogen
•
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.
Do not connect the jump leads to any
•
fuel system component or any moving
part. Be careful of hot engine parts.
The battery contains sulphuric acid,
•
which can cause serious burns.
If sulphuric acid comes into contact
•
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.
Never smoke near the battery.
