other products and therefore cannot be
held responsible for them, even if in indi-
vidual cases an official approval or authori-
zation by governmental or other agencies
should exist. Use of such parts and acces-
sories could adversely affect the safety,
performance or reliability of your vehicle.
Please do not use them.Genuine Mercedes-Benz parts as well as
conversion parts and accessories

tion will be performed.

80 Safety and SecurityDriving and safety systemsLOW RANGE 4-ETS
During off-road driving, a special low range
system for the 4-ETS is operational with
transmission in LOW RANGE mode.
More information can be found in the
“Practical hints” section (
page 242) and
(
page 252).
EBP
The EBP enhances braking effectiveness
by allowing the rear brakes to supply a
greater proportion of the braking effort
without a loss of vehicle stability.
ESP
The Electronic Stability Program (ESP)
monitors the vehicle’s traction (force of ad-
hesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle. The ESP is especially
useful while driving off and on wet or slip-
pery road surfaces.
The 4-ETS / ESP warning lampv in the
speedometer flashes when the ESP is en-
gaged.
The ¿indicator lamp in the instrument
cluster (
page 25) and the 4-ETS / ESP
warning lampv in the speedometer
come on when you turn the key to
position2. They go out when the engine is
running.
Warning!
G
Never switch off the ESP when you see the
4-ETS / ESP-warning lampv flashing in
the speedometer. In this case, proceed as
follows:

While driving off, apply as little throttle
as possible.


While driving, ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.

Daytime running lamp mode
Canada only:
Turn combination switch to
positionM orU.
When the engine is running, the low beam
headlamps are automatically switched on.

124 Controls in detailAutomatic transmissionTowing a trailer
If you tow a trailer, note the following
points:

Manually shift to a lower gear range
(4,3, 2, 1), if the transmission hunts
between gears on inclines
(page 121).
A lower gear range and reduction of
speed reduces the change to overload
or overheat the engine.


At very steep inclines switch transfer
case to LOW RANGE mode
(page 125).
For more information on trailer towing, see
the “Operation” section (
page 206).Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only second gear and reverse gear
can be activated.
Stop the vehicle.

Move gear selector lever to positionP.

Turn off the engine.

Wait at least ten seconds before
restarting.

Restart the engine.

Move selector lever to positionD
(for second gear) orR.

Have the transmission checked at an
authorized Mercedes-Benz Light Truck
Center as soon as possible.

136 Controls in detailAutomatic climate controlThe automatic climate control is operatio-
nal whenever the engine is running. You
can operate the climate control system in
either the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burns or frostbite on unprotected skin
in the immediate area of the air vents.
Always keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 138).
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A
clogged filter will reduce the air volume
to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not touch the interior temperature
sensor to maintain a precise tempera-
ture.
The set value is indicated by a lighted
segment on the control wheels.

174 Controls in detailUseful featuresOnce the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
EMERGENCY CALL –
CONNECTING CALL
appears in the MCS dis-
play. When the connection is established,
the message
EMERGENCY CALL –
CALL CONNECTED
appears in the MCS dis-
play. All information relevant to the emer-
gency, such as the location of the vehicle
(determined by the GPS satellite location
system), vehicle model, identification num-
ber and color are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
When a voice connection is established the
audio system mutes and the message
TELE AID – EMERGENCY CALL ACTIVE
ap-
pears in the MCS display. The Response
Center will attempt to determine more pre-
cisely the nature of the accident provided
they can speak to an occupant of the vehi-
cle.The Tele Aid system is available if:


it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time


the relevant cellular phone network
and GPS signals are available and pass
the information on to the response cen-
ter.iLocation of the vehicle on a map is only
possible if the vehicle is able to receive
signals from the GPS satellite network
and pass the information on to the re-
sponse center.
Warning!
G
If the indicator lamp in the SOS button is il-
luminated continuously and there was no
voice connection to the Response Center
established, then the Tele Aid system could
not initiate an emergency call (e.g. the rele-
vant cellular phone network is not available).
The message
EMERGENCY CALL –
CALL FAILED appears in the MCS display
for approx. ten seconds.
Should this occur, assistance must be sum-
moned by other means.
