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 positionN (
page 394)

you cannot release the electronic parking
brake
For information on charging the starter battery
see “Batteries” (
page 655) or see “Jump start-
ing” (
page 660).
!Make sure that the electronic parking brake
is released. If the electronic parking brake is
malfunctioning, release it mechanically
(
page 637).
!If the vehicle is towed with the front axle
raised, 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 positionN and the SmartKey or
SmartKey with KEYLESS-GO* must be in starter
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 with all wheels on the
ground or with the front axle raised, the trans-
mission must be in positionN.
If you turn off the engine using

the SmartKey and

remove the SmartKey from the starter
switch
or

open a door

the KEYLESS-GO* start/stop button and
open a door
the transmission will shift to park position P
