Jump-starting using the battery from another vehicleFig. 155
- Discharged battery,
- power-supplying bat-
tery / ground point of the engine for the START-STOP system
Read and observe
on page 139 first.
If, because of a discharged battery, it is not possible to start the engine, the
battery of another vehicle can be used to start the engine. To do this, jump-
start cables are required which have a sufficiently large cross-section and in-
sulated terminal clamps.
The rated voltage of the two batteries must be 12 V. The capacity (Ah) of the
power-supplying battery must not be significantly lower than the capacity of
the discharged battery. Otherwise, the vehicle may not start with the dis-
The jump-start cables must be attached in the following sequence.
to the positive terminal of the discharged battery.
to the positive terminal of the power-supplying battery.
to the negative terminal of the power-supplying battery.
For vehicles with the START-STOPsystem, attach clamp
to the ground
point of the engine
» Fig. 155 .
For vehicles without the START-STOPsystem, attach clamp
to a solid
metal part firmly attached to the engine block or directly to the engine block.
Start the engine on the vehicle providing the power and allow it to idle.
Initiate the starting process in the vehicle with the discharged battery.
If the engine does not start within 10 s, then cancel the starting procedure
and repeat after half a minute.
Remove the jump start cables in the reverse order as attachment.
Never clamp the jump cable to the negative terminal of the discharged
battery - risk of explosion.■
The non-insulated parts of the terminal clamps must never touch each
other – there is a risk of short circuit.
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– there is a risk of short circuit.
Position the jump cables so that they cannot be caught in rotating parts
in the engine compartment - danger of injuries and the risk of vehicle dam-
Towing the vehicle
Information about the towing process
Braided tow rope / Spiral tow rope
To tow with a tow rope, only use a braided synthetic fibre rope » Fig. 156 -
Attach the tow rope or the tow bar only to the towing eye at the front
» page 141 .
Conditions for towing. Vehicles with automated manual transmission cannot be towed with the
rear wheels raised - risk of gearbox damage!
If the gearbox has no oil, your vehicle must be towed with the front axle
raised clear of the ground or on a breakdown vehicle or trailer.
