701 Practical hints
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
vehicle. Adapt your driving accordingly.
!When towing the vehicle with all wheels on
the ground or with the front axle raised, the start-
er battery must be connected and charged. Oth-
erwise:
you will not be able to switch on the ignition
you will not be able to engage the automatic
transmission in neutral positionN
(
page 402)
you cannot release the electronic parking
brake
For information on charging the starter battery
see “Batteries” (
page 692) or see “Jump start-
ing” (
page 697).
!Make sure that the electronic parking brake
is released. If the electronic parking brake is
malfunctioning, release it mechanically
(
page 673).
!If the vehicle is towed with the front axle
raised (not permissible for vehicles with
4MATIC), the automatic transmission must be in
positionN and the engine must be shut off
(SmartKey or SmartKey with KEYLESS-GO* in
starter switch position0 or1). Active braking
action through the ESP
® may otherwise seriously
damage the brake system.
When towing the vehicle with all wheels on the
ground, the automatic transmission must be
shifted to neutral positionN and the SmartKey
or SmartKey with KEYLESS-GO* must be in start-
er switch position2.
!When towing the vehicle with all wheels on
the ground or the front axle raised, the vehicle
may be towed only for distances up to 30 miles
(50 km) and at a speed not to exceed 30 mph
(50 km/h).
!If the vehicle is towed, the transmission
must be in neutral positionN.
If you turn off the engine using
the SmartKey and
remove the SmartKey from the starter
switch
or
open a front door
the KEYLESS-GO* start/stop button and
open a front door
the transmission will shift to park positionP
automatically.
702 Practical hints
Towing the vehicle
If you want the gear position to remain in
neutral positionN, observe the following
instructions.
Vehicles with SmartKey:
With the vehicle at a standstill and the
ignition switched on shift the
automatic transmission to neutral
positionN.
If engaged, manually release the
electronic parking brake (
page 395).
Switch off the ignition and leave the
SmartKey in the starter switch.Vehicles with KEYLESS-GO*:
With the vehicle at a standstill, depress
the brake pedal and keep it pressed.
Shift the automatic transmission to
park positionP.
Release the brake pedal.
Remove the KEYLESS-GO start/stop
button from the starter switch
(
page 345).
Insert the SmartKey with KEYLESS-GO
into the starter switch.
With the ignition switched on shift the
automatic transmission to neutral
positionN.
If engaged, manually release the
electronic parking brake (
page 395).
Switch off the ignition and leave the
SmartKey with KEYLESS-GO in the
starter switch.
Warning!G
When leaving the SmartKey or SmartKey
with KEYLESS-GO* in the starter switch, do
not leave children unattended in the vehicle.
It is possible for children to switch on the
ignition which could result in unsupervised
use of vehicle equipment. Unsupervised use
of vehicle equipment could result in an
accident and/or serious personal injury.
iWhen towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey or SmartKey with KEYLESS-GO* 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 approxi-
mately 9mph (15km/h) or more.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 245).
iTo signal turns while being towed with the
hazard warning flasher in use, turn SmartKey or
SmartKey with KEYLESS-GO* in starter switch to
position2 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.
