—Position the leads in such a way that they cannot come into contact with any moving parts in the engine
compartment.
Starting the engine
—Start the engine of the vehicle providing assistance and let it run at idle.
—Start the engine of the vehicle with the discharged 12-volt vehicle battery and wait two or three minutes until the
engine is running “smoothly”.
Removing the jump leads
—Before disconnecting the jump leads, switch off the dipped beam headlights if they are switched on.
—Turn on the air conditioning system or the heating and fresh air system blower and the rear window heating in the
vehicle with the discharged 12-volt vehicle battery. This helps to minimise voltage peaks which are generated
when the leads are disconnected.
—When the engines are running, the jump leads should be removed only in the orderD – C – B – A → Fig. 1.
—Fit the cover to the positive terminal on the 12-volt vehicle battery.
—Go to a qualified workshop and have the 12-volt vehicle battery checked.
WARNING
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode, which can lead to serious
injuries. Please note the following in order to reduce the risk of the 12-volt vehicle battery exploding:
● All work on the 12-volt vehicle battery and the electrical system can cause serious chemical burns, fire or electric
shocks. Always read the warnings and safety information before carrying out any kind of work on the 12-volt
vehicle battery (→ 12-volt vehicle battery).
● Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle battery.
● Attach the connector cables in the correct order – the positive cable first, followed by the negative cable.
● Fit the positive terminal cover back onto the 12-volt vehicle battery after jump starting the vehicle.
● Never connect the negative cable to parts of the fuel system or to the brake lines.
● The non-insulated parts of the battery clamps must not be allowed to touch. The jump lead attached to the
positive terminal on the 12-volt vehicle battery must not touch metal parts of the vehicle.
● Check the battery window on the 12-volt vehicle battery using a torch if necessary. If the display is light yellow or
colourless, do not jump start the vehicle. Seek expert assistance.
● Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The gas emitted from the 12-volt
vehicle battery could be ignited by sparks.
● Do not use jump leads to activate the electric drive if the 12-volt vehicle battery is damaged or if it is or has ever
been frozen.
NOTICE
Once the vehicle has been successfully jump-started, go to a qualified workshop and have the 12-volt vehicle
battery checked.
Introduction
Towing requires some experience, especially when using a tow rope. Both drivers should be familiar with the
technique required for towing. Inexperienced drivers should not attempt to tow.
Make sure that no excessive pulling forces occur and take care to avoid jerking movements. When towing offroad,
there is always a risk of overloading the anchorage points.
