737 Practical hints
Towing the vehicle
Towing the vehicle
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.
When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC) only so far as neces-
sary to have the vehicle moved to a safe
location where the recommended towing
methods can be employed.!
To prevent damage during transport, do not
tie down vehicle by its chassis or suspension
parts.
!
Before towing the vehicle observe the fol-
lowing instructions:


Do not tow-start the vehicle.


Use flatbed or wheel lift/dolly equipment
with the ignition switched off.


Do not tow with sling-type equipment. Tow-
ing with sling-type equipment over bumpy
roads will damage radiator and supports.


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 suspen-
sion parts. For more information see “Install-
ing towing eye bolt” (
page 740).
i
If the battery is disconnected or discharged


the SmartKey will not turn in the starter
switch


the automatic transmission will remain
locked in park positionP.
For more information see “Batteries”
(
page 729) or “Jump starting” (
page 734).
