Breakdown assistance
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 318).
The automatic transmission automatically
shifts
to position P when you open the driver's
or front-passenger door or when you remove
the SmartKey from the ignition lock. In order
to ensure that the automatic transmission
stays in position N when towing the vehicle,
you must observe the following points:
X Make sure that the vehicle is stationary and
the SmartKey in the ignition lock is in
position 0.
X Turn the SmartKey to position 2 in the
ignition lock.
On vehicles with KEYLESS-GO, use the
SmartKey
instead of the Start/Stop button
(Y page 139).
X Depress and hold the brake pedal.
X Shift the automatic transmission to
position N.
X Release the brake pedal.
X Release the parking brake.
X Switch on the hazard warning lamps
(Y page 114).
X Leave the SmartKey in position 2 in the
ignition lock.
i When towing with the hazard warning
lamps switched on, use the combination
switch as usual to signal a change of
direction.
In this case, only the turn signals
for the desired direction flash. When the
combination switch is reset, the hazard
warning lamps start flashing again. Transporting the vehicle
! Only
lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components.

with either the front or the rear axle raised,
as doing so will damage the transmission.
If the vehicle has transmission damage or
damage to the front or rear axle, have it
transported on a transporter or trailer.
In the event of damage to the electrical
system
If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to position
N, you must provide power to the vehicle's
electrical system in the same way as when
jump-starting (Y page 317).
Have the vehicle transported on a transporter
or trailer. Tow-starting (emergency starting)
