Mobile Service

BMW Group's Mobile Service – Emer-
gency Service – is there to assist you in
the event of a breakdown, at any time
of the day or night, during weekends
and on public holidays.

The telephone numbers of the Mobile
Service – Emergency Service – centre in
your country are listed in the 'Service
Kontakt' brochure.

Starting with a flat battery

If the car's own battery is flat, the
engine of your BMW can be started by
using two jump leads from another
vehicle's battery. Conversely, you can
also jump-start another vehicle with
your BMW. Use only jump leads with
fully insulated battery-post clips.

Do not touch any electrically live
parts when the engine is running,

or a fatal accident may occur. Do not
depart from the procedure described
below, otherwise personal injury could
result or one or both vehicles be dam-
aged.

Preparation

1. Check that the other vehicle's battery

has a voltage of 12 V and is rated at
more or less the same capacity in Ah.
This information is on the battery

2. Switch off the engine of the donor

vehicle

3. Switch off all consumers in both

vehicles.

Make sure that the bodies of the
two vehicles do not touch, as oth-

erwise there is a risk of short-circuit.

Connecting jump leads

Always maintain the correct order
when attaching the jump leads,

otherwise there is a risk of sparks
occurring and causing injury.

Your BMW's jump-starting connection
in the engine compartment acts as the
positive terminal of the battery, see also
