Starting engine

Start the engine of the assisting vehicle and
let it run at a slightly elevated idling speed
for a few minutes.

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.

Let the engines run for a few minutes.

Disconnect the jumper cables by reversing
the connection sequence.

If need be, have the battery checked and
recharged.

Never use spray fluids to start the
engine.

Tow starting and towing

Obey all applicable laws and guidelines
for tow starting and towing.

Do not allow any passengers other than
the driver to ride in a vehicle that is being

towed.

Using tow fitting

The threaded tow fitting is stored in the
onboard tool kit, refer to page

104

, 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 only for towing 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 the vehicle can be dam-
aged.

Access to screw thread

Front

Push the cover in the bumper out of the recess
with a screwdriver.

Rear

Press on the mark provided on the cover.

Being towed

Make sure that the ignition key is in posi-
tion 1; otherwise, the steering lock will

engage, making it impossible to steer the vehi-
cle. There is no power assist with the engine
switched off. It is therefore necessary to exert
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.

Manual transmission

Gearshift lever in neutral.

Automatic transmission

Selector lever in position N.
Changing selector lever positions, refer to
page

Do not exceed a towing speed of
45 mph/70 km/h and a towing distance

of 90 miles/150 km; otherwise, the automatic
transmission may be damaged.
