In the case of an accident, liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical
help if necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.

112 Controls in detailControl systemMultifunction steering wheel
The displays in the multifunction display
and the settings in the control system are
controlled by the buttons on the multifunc-
tion steering wheel.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.

144 Controls in detailDifferential locksA few words about differentials and dif-ferential locks
When a vehicle negotiates a turn, wheels
on the outside of the curve must travel far-
ther and rotate faster than the inside
wheels. The differential, the operation of a
set of gears that allows the powered
wheels in a vehicle to turn at different
speeds, make this essential function possi-
ble.
The drawback is that the differential also
sends most of the engine's power to the
wheel with the least load or strain on it. For
example, if one of a vehicle's powered
wheels sits on a patch of snow and spins
because there is no traction, all of the en-
gine's power will go to that wheel because
the power will take the path of least resis-
tance. Meanwhile, the opposite wheel, sit-
ting on dry pavement where it could get
enough grip to start the vehicle moving,
sits idle because it receives no power.The Electronic Traction System (ETS) ad-
dresses this problem and provides for
good control and steering ability by auto-
matically slowing the slipping wheel and
thus increasing the power to the other
non-slipping drive wheels to get the vehicle
moving. The ESP and ETS in this vehicle
feature such intelligent limited-slip differ-
ential technology, ideally suited for
on-road and light off-road driving. Transfer
case position LOW (
page 141) also en-
hances off-road driving capabilities
(
page 203).
More extreme off-road conditions may call
for another solution, engaging a differen-
tial lock or preventing the differential from
operating altogether. As part of its stan-
dard equipment, this vehicle comes with
three differential locks: front, transfer case
(center) and rear. Each can be engaged
simply by pushing dashboard-mounted
buttons in sequential order (center, rear,
front) (
page 145). When the transfer
case (center) differential is locked, half of
the engine's power is automatically distrib-
uted to the front wheels and half to the rear wheels. When the rear differential is
locked, power going to the rear wheels is
equally distributed, so that both rear
wheels turn at the same speed and torque.
When the front differential is locked, all
four wheels now turn with equal power and
torque. Please be aware that engaging the
differential locks will significantly reduce
the steering ability of the vehicle.
For your safety and the safety of others
and to prevent damage to the vehicle, the
differential locks must not be engaged
when driving on paved roads. It is impor-
tant to understand that during
on-road/paved driving, differentials are
absolutely necessary for providing the es-
sential control and steering ability of the
vehicle. The differential locks, therefore,
must not be engaged when driving on
paved roads and should only be used to
the extent necessary to negotiate off-road
conditions which can not be handled by
the systems (automatic 4-ETS, the ESP,
manual switch position “LOW” of transfer
case) this vehicle comes equipped with.

You can take and place telephone calls us-
ing the

buttons on the
steering wheel. Use the control system for
performing other telephone functions
(

mation on how to operate the telephone.
Tele Aid The Tele Aid system
(Telematic Alarm Identification on
Demand)
The Tele Aid system consists of three
types of response:


Automatic and manual emergency


Roadside Assistance and


Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press button
æ
and to lower,
press button
ç
.

To activate, press the SOS button, the
Roadside Assistance button
•
or
the Information button
¡
, depend-
ing on the type of response required.
Warning!
G
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle. Whether or not prohibited by law, for
safety reasons, the driver should not use the
cellular telephone while the vehicle is in mo-
tion.
Stop the vehicle in a safe location before an-
swering or placing a call.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using the
SOS button. Failure to complete either
of these steps will result in a system
that is not activated. If the system is
not activated, the indicator lamp in the
SOS button stays on after turning key
in starter switch to position2 and the
message
TELE AID – NOT ACTIVATED

will be shown in the multifunction dis-
play for approx. 10 seconds.
If you have any questions regarding ac-
tivation, please call the Response Cen-
ter at 1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).

Upgrade 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 lamps do not start flash-
ing after pressing one of the buttons or
remains illuminated (in red) at any
time, the Tele Aid system has detected
a fault or the service is not currently ac-
tive, and may not initiate a call. Visit
your Mercedes-Benz Light Truck Cen-
ter and have the system checked or
contact the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
as possible.
!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

tomer 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 Assis-
tance Center representative, except
Roadside Assistance and Information
calls, which can also be terminated by
pressing button

on the multifunc-
tion steering wheel.

Programming or reprogramming the in-
tegrated remote control
Turn key in the starter switch to
position1 or2.

Hold the end of the hand-held transmit-
ter of the device you wish to train
approximately 2 to 5 inches (5 cm to
12 cm) away from the surface of the in-
tegrated remote control located on the
inside rear view mirror, keeping the in-
dicator lamp in view.

Using both hands, simultaneously push
the hand-held transmitter button and
the desired integrated remote control
button. Do not release the buttons until
completing next step.

The indicator lamp on the integrated
remote control will flash, first slowly
and then rapidly. The rapid flashing
lamp indicates successful program-
ming of the new frequency signal.

When the indicator lamp flashes rapid-
ly, release both buttons.

To program the remaining two buttons,
repeat the above steps.
