Removing the jump leads Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
Turn on the heater blower and heated
rear window in the vehicle with the flat
battery. This helps minimise voltage
peaks which are generated when the
leads are disconnected.
When the engine is running, disconnect
the leads in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery ter-
minals.

no power supply or there is an el

em fault, the engine must be tow-started
to deactivate the electronic parking brake
and the electronic lock of the steering col-
umn. Towing instructions
Towing requires some expertise and experi-
ence, especially when using a tow r
ope
. Both
drivers should be familiar with the difficulties
involved in towing. For this reason, inexper-
ienced drivers should abstain from towing.
During towing, it should be ensured that no
impermissible tractive forces or shocks are
generated. When towing on an unpaved
road, there is always a risk of overloading and
damaging the anchorage points.
During towing, the towing vehicle can signal
the change of direction even with the hazard
warning lights turned on. To do so, at the
same time, the turn signal lever must be oper-
ated with ignition switched on. Meanwhile, the
hazard warning lights will go off. When the
turn signal lever is returned to the rest posi-
tion, the hazard warning lights will be auto-
matically reactivated. Notes for the driver of the towed vehicle
