Towing
278
>> Practical hints.
About towingsmart recommends that the vehicle be trans
ported with all wheels off the ground using
flatbed or appropriate wheel lift/dolly equip
ment.!
Use flatbed or wheel lift/dolly equipment
with the key in the starter switch in position0.
Do not tow with slingtype equipment. Towing
with slingtype equipment over bumpy roads
will damage radiator and supports.
To prevent damage during transport, do not
tie down the vehicle by its chassis or suspen
sion parts. Use the towing eye.
Switch off the towaway protection*
(page 78).
When circumstances do not permit the
recommended towing methods, the vehicle
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.
!
If the vehicle is towed with the front axle
raised, the gear selector lever must be in
neutral positionN and the engine must be shut
off (key in starter switch position0). Active
braking action through the ESP
® may other
wise seriously damage the brake system.
When towing the vehicle with all wheels on the
ground, the gear selector lever must be in
