Jump-starting using the battery from another vehicleFig. 188
Jump-starting:
- Discharged battery,
- power-supplying bat-
tery / ground point of the engine for the START-STOP system
Read and observe
on page 156 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.
The jump-start cables must be attached in the following sequence.
›
Attach clamp
1
to the positive terminal of the discharged battery.
›
Attach clamp
2
to the positive terminal of the power-supplying battery.
›
Attach clamp
3
to the negative terminal of the power-supplying battery.
›
For vehicles with the START-STOPsystem, attach clamp
4
to the ground
point of the engine
A
» Fig. 188 .
›
For vehicles without the START-STOPsystem, attach clamp
4
to a solid
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.
›
Detach the jumper cables in the exact reverse order that they were attached.
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 – 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
– 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.
Towing the vehicle
Information about the towing process
Fig. 189
Braided tow ropes/spiral tow rope
To tow with a tow rope, only use a braided synthetic fibre rope » Fig. 189 -
»
.
Attach the tow rope or the tow bar to the towing eyes at the front
» page 158 ,towing eyes at the rear » page 159or to thetowing device of the
trailer device » page 119 .
Conditions for towing. Cars with automatic gearboxes must not be towed with the rear wheels
raised - there is a 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.
