indicator lamp comes on while
driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP are also
switched off (see messages in display).
The brake system is still functioning normally
but without the ABS available.
Continue driving with added caution.
Wheels will lock during hard braking,
reducing steering capability.
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
Read and observe messages in the
display (
page 364).
The charging voltage has fallen below
10 volts. The ABS has switched off.
When the voltage is above this value
again, the ABS is operational again.
If necessary, have the generator (al-
ternator) and battery checked.

362 Practical hintsWhat to do if …?Vehicle status messages in the multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 145) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 134) or but-
ton k,j, è, orÿ on the
steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (page 134) or but-
ton k,j, è, orÿ on the
steering wheel. They are then stored in the
vehicle status message memory
(
page 145). Remember that clearing a
message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!

important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at

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-

Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.
Turn on the hazard warning flasher
(page 131).
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake (
page 55).
Move the gear selector lever toP.
Vehicles with SmartKey:
Turn off the engine (
page 56).
Remove the SmartKey from the starter
switch.Vehicles with SmartKey with
KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* start/stop button on the
gear selector lever once (
page 57).
Open the driver’s door (this puts the ig-
nition in position0, same as with the
SmartKey removed from the starter
switch). The driver’s door then can be
closed again.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling characteristics change
when driving with a spare wheel mounted.
Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
iOpen door only when conditions are
safe to do so.

426 Practical hintsTowing the vehicleWarning!
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 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 91).
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 158).
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.
