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. For more information, see

“Electro-hydraulic brake system”

(

page 86).

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

vehicle. Adapt your driving accordingly.

!

Towing of the vehicle should only be done

using the properly installed towing eye bolt.
Never attach tow cable, tow rope or tow rod to
the vehicle chassis, frame or suspension parts.

i

To signal turns while being towed with the

hazard warning flasher in use, turn SmartKey in
starter switch to position 2 and activate the
combination switch for the left or right turn
signal in the usual manner – only the selected
turn signal will operate.

Upon canceling the turn signal, the hazard
warning flasher will operate again.

i

When towing the vehicle with all wheels on

the ground, please note the following:

With the automatic central locking activated and
the SmartKey in starter switch position 2 the
vehicle doors lock if the left front wheel as well
as the right rear wheel are turning at vehicle
speeds of approximately 9 mph (15 km/h) or
more.

To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(

page 139) and switch off the tow-away alarm

(

page 94).

i

The gear selector lever will remain locked in

park position P and the SmartKey will not turn in
the starter switch if the battery is disconnected
or discharged. See notes on the battery
(

page 367).
