There is a jump lead connection point (earth connection) in the engine compartment for connecting
the black jump lead Fig. 176
The vehicle must be jump-started or used to jump-start another vehicle only via this jump lead
connection point.

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 DFig. 177
The black jump lead should never be connected to the negative terminal (-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.

NOTICE
When filling or changing service fluids, please ensure that the correct service fluids are filled through
the correct openings. The use of incorrect service fluids could result in serious malfunctions and
engine damage.
Service fluids that leak from the vehicle are harmful to the environment. For this reason, you should
regularly check the ground underneath your vehicle. If there are spots of oil or other fluids on the
ground, the vehicle should be inspected by a qualified workshop. Any spilt service fluids must be
disposed of properly.
