jumper cable to the negative battery termi-
nal or to an engine or body ground on the

Starting engine
1. Start the engine of the assisting vehicle and
allow it to run for several minutes at a fast
idle.
2. Start the engine on the other vehicle in the
usual way.
If the first start attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3. Allow the engines to run for several min-
utes.
4. Disconnect the jumper cables again in the
reverse sequence.
If need be, have the battery checked and
recharged.
Never use spray fluids to start the
engine.
<
Towing and tow starting
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
onboard tool kit and must 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 it will
go. 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,
damage to the tow fitting and the vehicle can
occur.
<
Access to screw thread
Press the arrow symbol to push out the cover.
Being towed
Do not tow the vehicle by the rear axle;
because there is no steering lock, the
wheels could turn to an extreme angle during
towing. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering.
<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
