Control system
Pressing any of the buttons on the multi-
function steering wheel will alter what is
shown in the multifunction display.
The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or sub-
menus.
The individual functions are then found
within the relevant menu (radio or CD op-
erations under
AUDIO
, for example). These
functions serve to call up relevant informa-
tion or to customize the settings for your
vehicle.It is helpful to think of the menus, and the
functions within each menu, as being ar-
ranged in a circular pattern.
If you press buttonè orÿ
repeatedly, you will pass through each
menu one after the other.
If you press buttonk orj
repeatedly, you will pass through each
function display, one after the other, in
the current menu.In the
SETTINGS
menu, instead of functions
you will find a number of submenus for
calling up and changing settings. For in-
structions on using these submenus, see
the “Settings menu” section (
page 132).
The number of menus available in the sys-
tem depends on which optional equipment
is installed in your vehicle.
iThe headings used in the menus table
are designed to facilitate navigation
within the system and are not neces-
sarily identical to those shown in the
control system displays.
The first function displayed in each
menu will automatically show you
which part of the system you are in.

204 Controls in detailUseful featuresUpgrade Signals
The Tele Aid system processes calls using
the following priority.
Automatic emergency – First priority
Manual emergency – Second priority
Roadside Assistance – Third priority
Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard and the
appropriate indicator lamp will stop flash-
ing. The COMAND system operation will
resume.
!If the indicator lamp continues to flash
or the system does not reset, contact
the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada), or
Mercedes-Benz Customer Assistance
at 1-800-FOR-MERCedes
(1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100
in Canada.iThe indicator lamp in the respective
button flashes until the call is conclud-
ed. Calls can only be terminated by a
Response Center or Customer
Assistance Center representative, ex-
cept Roadside Assistance and
Information calls, which can also be
terminated by pressing buttont on
the multifunction steering wheel.
iWhen a Tele Aid call has been initiated,
the COMAND system audio is muted
and the selected mode (radio or CD)
pauses. The optional cellular phone (if
installed) switches off. If you must use
this phone, the vehicle must be parked.
Disconnect the coiled cord and place
the call. The navigation system (if en-
gaged) will continue to run. The display
in the instrument cluster is available for
use and spoken commands are only
available by pressing the RPT button on
the COMAND unit. A pop-up window
will appear in the COMAND display to
indicate that a Tele Aid call is in
progress.
288 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on ignition,
have the respective bulb checked and re-
placed if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS indicator lamp
comes on while driving.
You engaged the differential locks. The ABS,
ESP, BAS, EBB and 4-ETS are switched off.
The driving systems will switch on
again after the differential locks have
been disengaged.
The ABS has detected a malfunction and has
switched off. The ESP, BAS, EBB and 4-ETS
are also switched off (see messages in dis-
play).
If the ABS control unit is malfunctioning, oth-
er systems such as the navigation system or
Rear Parking Assist* may also malfunction.
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 Light Truck
Center as soon as possible.
Failure to follow these instructions in-
creases the risk of an accident.

ning while the other wheel stands still,
resulting in driving force no longer be-
ing transferred.Cruise control

matically maintains the vehicle speed
set by the driver.
