418 Practical hints
Towing the vehicle
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 power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
i
To signal turns while being towed with
the hazard warning flasher in use,
switch on the ignition and activate the
combination 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 warning flasher will operate
again.
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.
!
When towing the vehicle with all wheels
on the ground, please note the
following:
With the automatic central locking
activated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
Switch off the tow-away alarm*
(
page 90).
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 147).
Towing of the vehicle should only be
done using the properly installed
towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle
chassis, frame or suspension parts.

Rims and Tires
i
The following pages also list the ap-
proved wheel rim and tire sizes for
equipping your vehicles with winter
tires. Winter tires are not available as
standard or optional factory equip-
ment, but can be purchased from an
authorized Mercedes-Benz Center.
Depending on vehicle model and the
standard or optional factory-equipped
wheel rim/tire configuration on your
vehicle (Sport Package etc.), equipping
your vehicle with winter tires approved
for your vehicle model may also require
the purchase of two or four wheel rims
of the recommended size for use with
these winter tires. See an authorized
Mercedes-Benz Center for more infor-
mation.

!
Please compare the recommended tire
inflation pressure for your vehicle with
the tire inflation pressure on the yellow
label located on the spare wheel rim.
If the tire inflation pressure on the yel-
low label on the spare wheel rim differs
from the values given in this Operator’s
Manual, inflate the collapsible tire to
the recommended tire inflation pres-
sure given on the yellow label on the
spare wheel rim.
i
Please note that the tire inflation
pressure of the collapsible tire differs
from the tire inflation pressure of the
road tires.
Inflate the collapsible tire to approxi-
mately 51 psi (3.5 bar).
