Towing the vehicle
iTo signal turns while being towed with 
the hazard warning flasher in use, turn 
SmartKey in starter switch to 
position2 and activate the combina-
tion switch for the left or right turn sig-
nal in the usual manner – only the 
selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels 
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter 
switch position2, or KEYLESS-GO* 
start/stop button in position2, the ve-
hicle doors lock if the left front wheel 
as well as the right rear wheel are turn-
ing at vehicle speeds of approximately 
9 mph (15 km/h) or more.
Switch off the tow-away alarm 
(page 103).
To prevent the vehicle door locks from 
locking, deactivate the automatic cen-
tral locking (
page 129). 
Towing of the vehicle should only be 
done using the properly installed tow-
ing eye bolt. Never attach tow cable, 
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.
iThe gear selector lever will remain 
locked in positionP and the SmartKey 
will not turn in the starter switch if the 
battery is disconnected or discharged.
