Steering oil
Visit workshop
The steering gear oil level is too low. There
is a danger of steering gear damage.
Have the system checked by an autho-
rized Mercedes-Benz Center.
Warning!
G
If the level of steering gear oil in reservoir is
too low, the steering power assistance could
fail. Much greater effort will then be needed
to turn the steering wheel.
Do not add steering oil without checking the
steering system.
Do not drive the vehicle. Have the system
checked at an authorized Mercedes-Benz
Center as soon as possible.
459 Practical hints
Towing the vehicle
Warning!
G
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position
2.
If the SmartKey is left in starter switch posi-
tion
0 for an extended period of time, it can
no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
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 sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
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.iTo 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 haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, or KEYLESS-GO*
start/stop button in position2, the ve-
hicle doors lock if the left front wheel
as well as the right rear wheel are turn-
ing at vehicle speeds of approx. 9 mph
(15 km / h) or more.
Switch off the tow-away alarm
(page 94).
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 159).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.
