367 Practical hints
Towing the vehicle
Warning!
G
The brake system requires electrical power 
to operate.
A malfunction in the vehicle’s power supply 
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver 
must then apply significantly greater brake 
pedal pressure and depress the pedal much 
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the 
brake pedal. Brakes are only applied to the 
front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. SBC brake system (
page 81).
With the engine not running, there is no 
power assistance for the brake and steering 
systems. In this case, it is important to keep 
in mind that a considerably higher degree of 
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.
!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 approx. 9 mph 
(15 km / h) or more.
To prevent the vehicle door locks from 
locking, deactivate the automatic cen-
tral locking (
page 105). 
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. 
See notes on the battery (
page 358) 
or on jump starting (
page 363).
