Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. 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 equipment
with SmartKey in starter switch turned to
position
0 .
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 and the automatic
central locking.
!
If the vehicle is towed with the front axle
raised, the gear selector lever must be in
position
N and the engine must be shut off
(SmartKey in starter switch position 0 or 1 ).
Otherwise, the ESP
®
will immediately be en-
gaged and will apply the rear wheel brakes.
When towing the vehicle with all wheels on the
ground, the gear selector lever must be in
position
N and the SmartKey must be in starter
switch position 2 .
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).
To be certain to avoid a possibility of damage to
the transmission, however, we recommend the
drive shaft be disconnected at the rear axle drive
flange for any towing beyond a short tow to a
nearby garage.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
앫
the engine will not run
앫
there is a malfunction in the
electro-hydraulic brake system
앫
there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position 2 .
If the SmartKey is left in starter switch
position 0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
