Jump starting the vehicle
The discharged 12-volt vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
Comply with the information on jump starting contained in the owner’s manual for the other vehicle.
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:
● Always wear suitable eye protection and protective gloves.
● Attach the connecting cables in the correct order – the positive cable first, followed by the negative cable.
● Never connect the negative lead to parts of the fuel system or to the brake lines.
● Do not allow the uninsulated parts of the terminal clamps to touch each other.
● Do not allow leads attached to the positive battery terminal on the 12-volt vehicle battery to touch electrically
conductive parts of the vehicle.
● 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 perform jump starting if the 12-volt vehicle battery is damaged or if it is frozen or has been frozen.
Attaching the jump leads
Fig. 1 How to connect the jump leads.
1
Vehicle with discharged 12-volt vehicle battery with jump-start connection point Plus, that is being jump
started.

3
Vehicle with 12-volt vehicle battery that is supplying power and jump-starting the other vehicle.
Suitable earth connection: Preferably the jump start connection point(earth connection), otherwise a solid
metal part which is securely bolted onto the cylinder block, or the cylinder block itself.
The jump leads should be connected only in the orderA – B – C – D → Fig. 1.
The black jump lead should never be connected to the negative terminal –( ) on the 12-volt vehicle battery.
Connecting the lead to the negative terminal can cause incorrect condition evaluation of the 12-volt vehicle battery
in the vehicle electronics.
1. Switch off the ignition in both vehicles .
