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).
