It is vital to make sure that
쎲
the capacitance of the battery supplying the
power (e.g. 45 Ah) does not lie substantially
below that of the discharged battery;
쎲
only batteries of identical nominal voltage (e.g.
12 V) are connected together;
쎲
there is no contact between the body work of the
vehicles involved (risk of short-circuiting);
쎲
sources of ignition (e.g. naked lights, burning
cigarettes or electric sparks) are kept away from
the batteries (risk of detonation) and that you
avoid bending over the batteries due to risk of
caustic burns;
쎲
the electrolyte of the discharged battery is still
fluid at low temperature;
쎲
the discharged battery is not disconnected from
its vehicleʼs electric system and that the ignition
of both vehicles is switched off before connecting
up the jumper cables: vehicles with manual
transmissions - place the shift lever in neutral;
vehicles with automatic transmissions - place the
selector lever in position „P“ and pull the hand
brake;
쎲
the leads of the jumper cable cannot get caught
up in any moving parts inside the engine
compartment;
쎲
you know how and in which order you have to
connect and disconnect the jumper cables.
쎲
when you remove the leads of the jumper cable
they do not come into contact with any moving
parts of the engine.
Connecting the jumper leads:
Connect the lead with the red pole clamps first to the
positive pole of the discharged battery (see
Figure/Item 1) and then to the positive pole of the
supplier battery (see Figure/Item 2). Now connect the
lead with the black pole clamps to the negative pole
of the supplier battery (see Figure/Item 3) and then
to ground on the receiver vehicle, e.g. the ground
strap or some other bare point on the engine block
(see Figure/Item 4). Choose a point as far away as
possible from the battery in order to avoid the ignition
of any electrolytic gas which may develop.
Starting:
Start the engine of the supplier vehicle and rev up to
the medium speed range. Then start the engine of
the receiver vehicle. Try for no longer than 15
seconds to start the vehicle, then wait for 1 minute
before trying again.
Disconnecting the jumper leads:
When the engine is running smoothly (after 2 to 3
minutes), disconnect the jumper cables in reverse
order: First disconnect the black pole clamp from the
ground strap or the engine block of the receiver
vehicle (see Figure/Position 4). Then disconnect the
other black pole clamp from the negative pole of the
supplier battery (see Figure/Item 3). Finally, remove
the two red pole clamps in any order.

Notes:
Starting cars with catalytic converters
If the battery is not able to start the engine, only jump
start it with the jump cables and auxiliary battery. If
you attempt to push off the car or tow it, petrol may
get into the exhaust and damage the catalytic
converter. Switch on a large power consumer before
disconnecting so as to prevent voltage surges in the
electrical system. Refer to the ownerʼs manual for the
car or additional equipment (such as car phone, on-
board computer, etc.) for instructions on charging the
battery and jump starting.
