710 Practical hintsTowing the vehicleMercedes-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 axle raised only so far
as necessary 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 713).
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 702) or “Jump starting” (
page 707).

711 Practical hints
Towing the vehicle
Towing with front wheels raised

Vehicles with KEYLESS-GO*: Remove
the KEYLESS-GO start/stop button

Warning!
G
When leaving the SmartKey or SmartKey
with KEYLESS-GO* in the starter switch, do
not leave children unattended in the vehicle.
It is possible for children to switch on the
ignition which could result in unsupervised
use of vehicle equipment. Unsupervised use
of vehicle equipment could result in an
accident and/or serious personal injury.
!
Keep in mind that it is important for the
SmartKey to be left in starter switch with the ig-
nition switched off. As soon as the SmartKey is
removed from the starter switch the automatic
transmission will shift to park positionP.
!
Make sure that the ignition is switched off.
If the starter switch is in position2, active brak-
ing action through the ESP
® may otherwise seri-
ously damage the brake system.
!
The vehicle may be towed only for distances
up to 30 miles (50 km) and at a speed not to ex-
ceed 30 mph (50 km/h).

712 Practical hintsTowing the vehicleTowing with all wheels on the ground

Switch on the ignition.

Shift the automatic transmission to
neutral positionN.

If engaged, manually release the
electronic parking brake.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the brake
system


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain the SmartKey is in
starter switch position2.
Warning!
G
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 ve-
hicle. Adapt your driving accordingly.
!
Keep in mind that it is important to have the
ignition switched on. As soon as the SmartKey is
removed from the starter switch or the SmartKey
with KEYLESS-GO* is removed from the vehicle,
the automatic transmission will shift to park
positionP.
!
The vehicle may be towed only for distances
up to 30 miles (50 km) and at a speed not to ex-
ceed 30 mph (50 km/h).
i
To signal turns while being towed with the
hazard warning flasher in use, the ignition must
be switched on. You can then activate the com-
bination switch for the left or right turn signal in
the usual manner – only the selected turn signal
will operate.
Upon canceling the turn signal, the hazard warn-
ing flasher will operate again.
