les must not touch each other, as any contact could mean that electricity could flow as
soon as the positive terminals are connected.
Jump lead connection point (earth connection)
Fig. 176 In the engine compartment: jump lead connection point (earth connection).
First read and observe the introductoryinformation and safety warnings⇒Introduction
There is a jump lead connection point (earth connection) in the engine compartment for connecting
the black jump lead ⇒ Fig. 176 ㊀.
The vehicle must be jump-started or used to jump-start another vehicle only via this jump lead
connection point.

Key to ⇒ Fig. 177 :
Vehicle with discharged 12-volt vehicle battery that is being jump-started.
Vehicle with 12-volt vehicle battery that is supplying power and jump-starting the other
vehicle.
Suitable earth connection: preferably the jump lead connection point (earth connection), a
solid metal part which is securely bolted onto the cylinder block, or the cylinder block itself.
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.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about a minute.
If the engine still does not start, seek expert assistance.
Attaching the jump leads
The jump leads should be connected only in the order A – B – C – D⇒ Fig. 177 .
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.
