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. Use only jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Carefully adhere to the follow-
ing sequence, both to prevent damage to one or
both vehicles, and to guard against possible
personal injuries.
