There must not be any contact between
the bodies of the two vehicles; otherwise,
there is a danger of short circuiting. <
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables. <
In your BMW, the so-called jump-starting termi-
nal for jump starting in the engine compartment
serves as a positive terminal for the battery, also
refer to engine compartment overview on
page
217 . The cover cap is marked with a +.
1. Fold open the cover of the BMW jump-
starting terminal. To do so, pull the tab.
2. Attach one end of the jumper cable plus/+
to the positive terminal of the battery or a
jump-starting terminal of the vehicle provid-
ing assistance.
3. Attach the second end of the cable to the
positive terminal of the battery or to a jump-
starting terminal of the vehicle to be started.
4. Attach one end of the jumper cable minus/–
to the negative terminal of the battery or to
an engine or body ground of the vehicle
providing assistance.
Your BMW has a special nut as body ground
or negative terminal.
5. Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.
Starting engine
1. Start the engine on the assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2. Start the engine on the other vehicle in the
usual way.
If the first starting attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3. Let the engines run for a few minutes.
4. Disconnect the jumper cables by reversing
the connection sequence.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.
<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.
<
Do not transport any passengers other
than the driver in a vehicle that is being
towed. <
Using tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page
223 , and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Use the tow fitting for towing only on roads.
Avoid lateral loading of the tow fitting, e.g. do
not lift the vehicle by the tow fitting. Otherwise,
the tow fitting and vehicle can be damaged.
