418 Practical hintsTowing the vehicle
!
To be certain to avoid a possibility of
damage to the drivetrain, however, we
recommend the drive shaft be discon-
nected at the rear axle drive flange
(vehicles with 4MATIC: disconnected at
the front and rear axle drive flanges) for
any towing beyond a short tow to a
nearby garage.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
the engine will not run
there is a malfunction in the power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
iTo signal turns while being towed with
the hazard warning flasher in use,
switch on the ignition 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.

Towing the vehicle
Warning!
G
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
following:
With the automatic central locking
activated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
Switch off the tow-away alarm*
(page 95).
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 152).
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 vehicle
chassis, frame or suspension parts.
iIf the battery is disconnected or
discharged
the SmartKey will not turn in the
starter switch. For more informa-
tion, see “Battery” (
page 412)
and “Jump starting” (page 415).
the gear selector lever will remain
locked in positionP. For informa-
tion on manually unlocking the
transmission gear selector lever
see (
page 392).
