It is located in the toolkit in the luggage com-
partment lid, refer to page203.

panel in the cargo area, refer to page203.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread

the arrow symbol on the cover panel.

Being towed
Make sure that the ignition is switched on,
refer to page56, 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 page212. 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.
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 Gearbox
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.
