Starting with a flat battery

If the car's own battery is flat, your BMW's
engine can be started by using two jump leads
from another vehicle's battery. In the same way,
you can help another car to start. Use only leads
with fully insulated terminal clamps.

Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Do not depart from the proce-
dure described below, otherwise personal
injury could result or one or both vehicles be
damaged.<
Preparations
1. Check whether the battery of the other
vehicle has a voltage of 12 Volt and approx-
imately the same capacity in Amp/h. This
should be printed on the battery.
2. Switch off the engine of the donor vehicle.
3. Switch off any consumers in both vehicles.
The bodies of the two vehicles must not
make contact, otherwise there is the risk
of a short-circuit.<
Connecting the jump leads
Connect the jump leads in the correct
order, so that no sparks which could
cause injury occur.<
With your BMW the so-called jump-starting
connection in the engine compartment acts as
the battery's positive terminal. Its cap is
marked +.
1. Remove the cap from the BMW jump-start-
ing connection, arrow 1.
2. Connect a terminal clamp on the positive/+
jump lead to the positive battery terminal or
to a jump-starting connection on the donor
vehicle.
3. Connect the other terminal clamp to the
battery's positive terminal or to a jump-
starting connection on the vehicle to be
started.
