engage the parking brake, activate
P (Park) mode and then put the starter
switch in the STOP position;
should you be using the battery of
another car, park the other car within
the range of the cables used for the
connection, operate the parking brake
and ensure that its ignition is off.
WARNING If the auxiliary battery is
installed on another vehicle, check that
there is no accidental contact of metal
parts between the two vehicles, since an
earth connection may result, with the risk
of serious injury to any people who may
be nearby.
WARNING If the procedure below is
carried out incorrectly, it can cause
severe injury to people or damage
the recharging system of one or
both vehicles. Carefully follow the
instructions given below.
Cable connection
74)
Proceed as follows to carry out a jump
starting:
connect a terminal on the end of the
positive cable from the remote positive
pole (+) of the car with flat battery;
connect the terminal on the opposite
end of the positive (+) cable to the
positive (+) pole of the auxiliary battery;
178
connect a negative cable end terminal
to the negative (-) pole of the auxiliary
battery;
connect the terminal on the opposite
end of the negative (-) cable to the earth
point (-) on the car with the battery flat;
start the engine of the car with an
auxiliary battery, let it run for some
minutes at idle and then start the engine
of the car with flat battery.
In case a portable battery is used, before
starting the car, wait a few seconds after
completing the connection.
Cable disconnection
Once the engine is started, remove the
connection cables in reverse sequence,
as shown below:
disconnect the negative cable end
terminal (-) from the earth point (-) of the
car with flat battery;
disconnect the terminal on the
opposite end of the negative cable from
the negative (-) pole of the auxiliary
battery;
disconnect the terminal on the
opposite end of the positive (+) cable
from the positive (+) pole of the auxiliary
battery;
disconnect the terminal on the end
of the positive cable from the remote
positive pole (+) of the car with flat
battery.
WARNING
186) Do not get too close to the radiator
cooling fan: the electric fan may start;
danger of injury. Scarves, ties and other
loose clothing might be pulled by moving
parts.
187) Remove any metal objects (e.g. rings,
watches, bracelets), that might cause an
accidental electrical contact and cause
serious injury.
188) The batteries contain acid that can
burn skin or eyes. Batteries produce
hydrogen, which is easily flammable and
explosive. Thus keep away flames or
devices which may cause sparks.
IMPORTANT
73) Never use a fast battery charger to
start the engine as this could damage the
electronic systems, particularly the engine
ignition and fuel supply control units.
74) Do not connect the cable to the negative
terminal (–) of the flat battery. The following
spark could lead to battery explosion and
cause serious harm. Only use the specific
earth point; do not use any other exposed
metallic part.
