BA tter Y: troubleshooting (1/2)
Starting the vehicle using the
battery from another vehicle
If you have to use the battery from an-
other vehicle to start, obtain suitable
jump leads (with a large cross section)
from an approved dealer or, if you al -
ready have jump leads, ensure that
they are in perfect condition.
the two batteries must have an iden-
tical nominal voltage of 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah) which
is at least the same as that of the dis-
charged battery.
Special procedures may be
required to charge some
batteries. Contact an ap -
proved Dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well-venti -
lated area.
Risk of serious injury.
Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water. If necessary,
consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
The engine may be hot when car -
rying out operations in close prox -
imity. In addition, the engine cooling
fan can come on at any moment.
Risk of injury.
Deactivate the Stop and
Start function for any opera -
tion performed in the engine
compartment.
