Messages in the display
The control system shows warning and
malfunction messages in the multifunction
display.
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.
High priority messages appear in the mul-
tifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset knob (
page 21) or a
steering wheel button.
Other high priority messages and messag-
es of less immediate priority (regular dis-
play colors) can be cleared from the
multifunction display using the reset knob
or one of the steering wheel buttons.
These are then stored in the malfunction
message memory (
page 118).Selecting the malfunction memory menu in
the control system (
page 118) displays
both cleared and uncleared messages.On the pages that follow, you will find a
compilation of all the messages that may
appear in the display. High priority mes-
sages appear on a red background.

as possible at an authorized Mercedes-Benz
Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz

Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See your autho-
rized Mercedes-Benz Center for headlamp
adjustment
iIf the headlamps are fogged up on the
inside as a result of high humidity, driv-
ing the vehicle a distance should clear
up the fogging.
iBackup bulbs will be brought into use
when the following lamps malfunction:

Notes on bulb replacement

Only use 12 volt bulbs of the same type
and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not light
up, visit an authorized Mercedes-Benz
Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:


the additional turn signals in the exteri-
or rear view mirrors


the high mounted brake lamp


the brake lamps


the parking lamps and the side marker
lamps in the tail lamp assemblies


the rear fog lamps


the low beam (Xenon or Bi-Xenon*)
lamps


the front fog lamps
Warning!
G
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:

touch or move it when hot,


drop the bulb,


scratch the bulb.
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

326 Practical hintsTowing the vehicleWarning!
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 SBC brake
system


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.
Prior to towing the vehicle with all wheels on
the ground, make certain that the key is in
starter switch position2.
If the key is left in the 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, re-
move key from starter switch and reinsert.
iTo signal turns while being towed with
the hazard warning flasher in use, turn
key in starter switch to position2 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.
Warning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its
limp-home (emergency operation) mode. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes are
only applied to the front wheels. Stopping
distance is increased! Adapt your driving
style accordingly. SBC brake system
(page 72).
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle. Adapt your driv-
ing accordingly.
