Towing the vehicle
Safety notes
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.
! To prevent damage during transport, do
not tie down vehicle by its chassis or sus-
pension parts.
If circumstances do not permit the recom-
mended towing methods, the vehicle may be
towed with all wheels on the ground or front
axle raised only so far as necessary to have
the vehicle moved to a safe location where
the recommended towing methods can be
employed.
X Switch off the tow-away alarm before tow-
ing the vehicle with all wheels off the
ground or front axle raised (
Y page 63).
! Before towing the vehicle observe the fol-
lowing instructions:
R Vehicles with automatic transmission:
Do not tow-start the vehicle. You could
otherwise seriously damage the auto-
matic transmission which is not covered
by the Mercedes-Benz Limited Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts.
i If the battery is disconnected or dis-
charged
R the SmartKey will not turn in the starter
switch
