Connect jumper cables in the following
sequence:
Always observe the sequence below:
1. Connect the positive lead (red) to the
positive termi nal of the discharged battery
first, then connect it to the positive terminal of
the donor battery.

then connect i t to a suitable grounding point on
the vehicle with the discharged battery. This
grounding point must lie as far as possible

par t or the engine blo ck are suitable grounding
points. If no suitable grounding points are to
be found on either vehicle, the negative cable

negative terminal of th e batt ery. If a suitable
grounding point is to be found on l y on the
donor vehicle, the negative cable mu st first be
connected to the terminal of the discharged
battery, then to the grounding point of the
donor vehicle.

loads such as the heated rear window and the
heating fan blower sh ould be switched on (the
vehicle s lights must not be sw itched on). This
