517 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground only so far as necessary to have
the vehicle moved to a safe location where
the recommended towing methods can be
employed.
!Use flatbed or wheel lift/dolly equipment,
with the SmartKey in starter switch turned to
position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Use the towing eyes.
Switch off the ESP
® (page 104) and the
automatic central locking (
page 130).
!Do not tow-start the vehicle.
!Do not tow with one axle raised. Doing so
could damage the transfer case, which is not
covered by the Mercedes-Benz Limited
Warranty.
All wheels must be on or off the ground. Observe
instructions for towing the vehicles with all
wheels on the ground.
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
Prior to towing the vehicle with all wheels on
the ground, make sure the starter switch is
in position2 (
page 39).
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, the automatic transmission must be
in positionN and the starter switch must be in
position2 (
page 39).
When towing the vehicle with all wheels on the
ground, 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).
Keep in mind that it is important for the
SmartKey to be in the respective starter switch
positions as described above. As soon as the
SmartKey is removed from the starter switch or
the SmartKey with KEYLESS-GO* is removed
from the vehicle, the automatic transmission will
shift to park positionP, see “Starter switch posi-
tions” (
page 39).
