406 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the 
ground using flatbed or appropriate wheel 
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the 
recommended towing methods, the vehi-
cle may be towed with all wheels on the 
ground or front wheels raised 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 equip-
ment with 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.
Switch off the tow-away alarm 
(page 87) and deactivate the auto-
matic central locking (
page 148).
!Vehicles with automatic transmission:
Do not tow-start the vehicle.
!If the vehicle is towed with the front 
axle raised, the engine must be shut off 
(SmartKey in starter switch position0 
or1). Otherwise, the ESP will immedi-
ately be engaged and will apply the rear 
wheel brakes.
When towing the vehicle with all wheels 
on the ground, the gear selector lever 
must be in positionN (manual trans-
mission: gears disengaged) and the 
SmartKey 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 dis-
tances up to 30 miles (50 km) and at a 
speed not to exceed 30 mph 
(50 km/h).
