Jump-starting
If the car's own battery is flat, your BMW's
engine can be starte d by connecting two
jumper cables to another vehicle's battery. You
can also use the same method to help start
another vehicle. Only use jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is runn ing, or a fatal acci-
dent may occur. Carefully adhere to the follow-
ing sequence, both to pr event damage to one or
both vehicles, and to guard against possible
personal injuries. <
Preparation
1.Check whether the ba ttery of the other
vehicle has a voltage of 12 volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2. Switch off the engine of the assisting vehi-
cle.
3. Switch off any consumers in both vehicles.
There must not be any contact between
the bodies of the two vehicles; otherwise,
there is a danger of shorting. <
Connecting jumper cables
Connect the jumper cables in the correct
order, so that no sparks which could
cause injury occur. <
Your BMW has a jump-starting connection in
the engine compartment which acts as the bat-
tery's positive terminal, refer also to the Engine
compartment overview on page 197. The cap is
marked with +.
1. Pull the cap of the BMW jump-starting con-
nection up to remove.
2. Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-aid terminal of the vehi-
cle providing assistance.
3. Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a star ting-aid terminal of
the vehicle to be started.
4. Attach one terminal clamp of the minus/–
jumper cable to the nega tive terminal of the
battery or to an engine or body ground of
the assisting vehicle.
Your BMW has a special nut as body ground
or negative pole.
