CAUTION
To avoid considerable damage to the vehicle
electrical system, note the following careful-
ly: ● If the jump leads are incorrectly connected,
this could result in a short circuit.
● The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected. How to jump start: description

without Start-Stop system. Fig. 134
Diagram of connections for vehicles
with Start-Stop system. Jump lead terminal connections
1. Switch off the ignition of both vehicles
››› .
2. Connect one end of the red jump lead to
the po s
itive + terminal of the vehicle
with the flat battery A
››› Fig. 133 .
3. C
onnect the other end of the red
jump
lead to the positive terminal + in the ve-
hicle providing assistance B .
4. For vehicles without Start-Stop system:
connect one end of the black jump lead to
the negative terminal – of the vehicle
providing the current B
››› Fig. 133 .
– For
vehicles with Start-Stop system: con-
nect one end of the black jump lead X to a
suitable ground terminal, to a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 134 . 5.
C
onnect the other end of the
black jump
lead X to a solid metal component bolted
to the engine block or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot come into contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boosting battery and let it run at idling
speed.
8. Start the engine of the vehicle with the flat battery and wait 2 or 3 minutes until the
engine is “running”.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam headlights (if they
are switched on).
10. Turn on the heater blower and heated rear
w indo
w in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.When the engine is running, disconnect the leads in reverse order to the details
given above.

Emergencies
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 143.
● The b att
ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow starting
Introduction When towing or tow starting, respect the le-
gal requirements.
For technical reasons, it is not possible to
tow a vehicle if the battery is flat. WARNING
A vehicle with a flat battery should never be
towed.
● Never remove the key from the ignition
lock. Otherwise, the steering wheel lock
could suddenly lock. The vehicle would not
be controlled and a serious accident could
ensue. WARNING
When towing the vehicle, the handling and
braking efficiency change considerably.
Please observe the following instructions to
minimise the risk of serious accidents and in-
jury:
● As the driver of the vehicle being towed:
– The brake must be depressed must hard-
er as the brake servo does not operate.
Always remain aware to avoid collision
with the towing vehicle.
– More strength is required at the steering
wheel as the power steering does not op-
erate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and
brake gently.
