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

Being towed
Make sure that the ignition is switched on,
refer to page59, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. If the vehicle
electrical system fails, do not tow-start or tow
the vehicle. The electric steering-wheel lock
cannot be unlocked and the vehicle cannot be
steered. For information on jump starting, refer to page232. There is no power assistance with
the engine stopped. This then requires
increased effort for braking and steering. Active
steering is deactivated and larger steering
wheel movements are required.<
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 position.
Automatic transmission
Selector lever in position N.
Changing selector lever position, refer to Deac-
tivating selector lever interlock page65.
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.<
SMG Sequential Manual Transmission
Engage selector lever position N with the igni-
tion switched on.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
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 offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
as attachment to other vehicle parts can
lead to damage.<
With 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.
Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
With tow truck for 525xi, 530xi
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.<
The BMW may only be transported on a flat
bed.
Tow-starting
Do not tow-start the vehicle if possible, but
instead start the engine by means of jump start-
ing, refer to page232. With a catalytic con-
verter, tow-starting should only be carried out
with the engine cold, and with automatic trans-
missions, the engine cannot be started by tow-
starting.
If the electrical system fails, do not tow-
start or tow the vehicle, otherwise the
electric steering-wheel lock cannot be
unlocked and the vehicle cannot be steered.<
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Switch on the ignition, refer to page59.
3.Shift into 3rd gear. For information on SMG,
see below.
4.Tow-start with the clutch completely
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch again completely.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
SMG Sequential Manual Transmission
1.Tow-start in selector lever position N.
2.Select the Sequential mode. The correct
gear will be selected and engaged automat-
ically.
Do not activate the HDC Hill Descent
Control of the 525xi, 530 xi during tow-
starting, refer to page89.<
