Jump-starting using the battery from another vehicle
Fig. 155 Jump-starting: - 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-
charged battery.
The jump-start cables must be attached in the following sequence.
›
Attach clamp
to the positive terminal of the discharged battery.
1
›
Attach clamp
to the positive terminal of the power-supplying battery.
2
›
Attach clamp
to the negative terminal of the power-supplying battery.
3
›
For vehicles with the START-STOPsystem, attach clamp
point of the engine

A
›
For vehicles without the START-STOPsystem, attach clamp
metal part firmly attached to the engine block or directly to the engine block.
Starting engine
›
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.

Do-it-yourself
WARNING
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-
age.

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.
