neath the cover on the right-hand side of the

underneath the cover on the left-hand side of
the cargo bay, refer to page221.

Being towed
Make sure that the ignition is switched on,
refer to page57, otherwise the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable. If the
electrical system fails, do not attempt to tow-
start or tow away the car. The electric steering
wheel lock cannot be disengaged and the car is
not steerable. Jump starting, refer to page230.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Switch on the hazard warning flashers, depend-
ing on local regulations.
Manual transmission
Gearshift lever in idle position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page60.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Towing methods
In come countries, it is illegal to tow your vehicle
with a tow bar or tow rope on public highways.
Please familiarize yourself with the relevant
towing regulations for the country in which you
are driving.
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
With a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<

With a tow truck
Without xDrive
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
With xDrive
Do not tow a BMW with xDrive with just
the front or rear axle raised, otherwise the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page230. Vehicles with a catalytic converter
should only be tow-started when the engine is
cold, vehicles with an automatic transmission
cannot be tow-started at all.
If the electrical system fails, do not tow or
tow-start the vehicle, as it would be
impossible to release the electric steering-wheel lock and the vehicle could not be
steered.<

with local regulations.
2.Switch on the ignition, refer to page57.
3.Shift into 3rd gear.

bar or rope and switch off the hazard warn-
ing flashers.
