192 Controls in detailAutomatic transmissionEmergency 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.

Shift to park positionP.

Turn off the engine.

Wait at least ten seconds before
restarting.

Restart the engine.

!Because off the ESP’s
® automatic
operation, the engine must be shut off
(SmartKey or SmartKey with
KEYLESS-GO* in starter switch
position1) when testing the brakes on
a brake test dynamometer and such
testing should be no longer than
10 seconds. Active braking action
through the ESP
® may otherwise
seriously damage the front or rear axle
brake system.
Operational or performance tests with
the engine running must only be con-
ducted on a two-axle dynamometer.
Otherwise, the transfer case or the
brake system can be damaged, which
is not covered by the Mercedes-Benz
Limited Warranty.
iThe vehicle is equipped with full-time
four-wheel drive. Both the front and
rear axles are powered at all times
when the vehicle is being operated.

200 Controls in detailGood visibility
Make sure the sun visor is properly en-
gaged in the mounting.

Lift the mirror cover2 to access the
mirror.
Mirror lamp3 switches on.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated
after approximately 6 to 17 minutes of
operation depending on the outside tem-
perature.Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

Climate control
Setting the temperature
Use temperature controls1 and7
(page 204) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).
The climate control will adjust to the set
temperature as fast as possible.Increasing

Turn the temperature control1
and/or7 slightly to the right.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.

Turn the temperature control1
and/or7 slightly to the left.

Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Light Truck Center.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the battery voltage.
Regardless of the temperature and air
volume set on the climate control panel
an interior temperature is aimed at by
72°F (22°C) and the blower runs for
the protection of the battery on low
stage.
