Jump starting
If the car's own battery is flat, your BMW's
engine can be started 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 running, or a fatal
accident may occur. Carefully adhere to the
following sequence, both to prevent damage
to one or both vehicles, and to guard against
possible personal injuries.<
Preparation
1. Check whether the battery of the other
vehicle has a voltage of 12 volts and
approximately the same capacitance in Ah.
This information can be found on the
battery.
2. Switch off the engine of the assisting
vehicle.
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 255. The cap is
marked with +.
1. Pull the cap of the BMW jump-starting
connection 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
vehicle providing assistance.
3. Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a starting-aid terminal of
the vehicle to be started.
4. Attach one terminal clamp of the minus/–
jumper cable to the negative 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.
5. Attach the second terminal clamp of the
minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
