Switch off the tow-away alarm before
towing the vehicle with all wheels on the
ground or one axle raised ( Y page 52).
! Before towing the vehicle observe the
following instructions:
R Vehicles with automatic transmission:
Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic 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. G
Warning!
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.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R Vehicles with automatic transmission:
the automatic transmission will remain in
park position P For more information see “Battery”
(Y page 282) or “Jump starting”
(Y page 283).

vehicle or you are being towed, the towing eye
bolt can be screwed into threaded holes
which are located behind covers on each

vehicle tool kit, located in the compartment
underneath the trunk floor (Y page 234).
