nal of the battery or to the engine or body

Starting the engine

Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.

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 above connecting sequence.

If necessary, have the battery checked and
recharged.

Never use spray fluids to start the
engine.

Tow-starting, towing away

Observe the applicable laws and regula-
tions for tow-starting and towing vehi-

cles.

Do not transport any passengers other
than the driver in a vehicle that is being

towed.

Using a tow fitting

The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
It is stored in the onboard tool kit underneath
the cover on the right-hand side of the cargo
bay, refer to page

Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the

tow fitting for towing on paved roads only. Avoid

the vehicle by the tow fitting. Otherwise the tow
fitting and the vehicle could be damaged.
