Transfer case
LOW RANGE mode*
The LOW RANGE mode is available on vehi-
cles with enhanced off-road package*.
In the following situations you should
switch to LOW RANGE mode:
앫
during off-road driving (
컄
page 357)
앫
when crossing water (
컄
page 362)
앫
when towing up or down on steep
gradients
With the LOW RANGE selected, the
engine’s power delivery and the shifting
behavior of the automatic transmission are
adjusted. Furthermore, the ABS, ESP
®
and
4-ETS functions especially adapted to
off-road travel are activated.
For information on driving safety systems
during LOW RANGE mode, see “Driving
safety systems” (
컄
page 103).
For more information on Off-road driving,
see “Off-road driving” (

Gear Ranges
There are two possible settings.
!
Operational or performance test must only
be conducted on a two-axle dynanometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!
Because the ESP
®
operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position
0 or 1 or
KEYLESS-GO* start/stop button in
position
0 or 1 ) when testing the parking brake
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 brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
i
The 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.
HIGH
RANGE Road position for all normal
driving situations.
(LOW RANGE mode off)
LOW
RANGE Off-road position for traveling
on rough terrain.
(LOW RANGE mode on)
Also use the off-road position
when driving on-road on steep
gradients, especially when
towing a trailer.
LOW RANGE acts by raising
the engine’s gear ratio. The ve-
hicle travels at roughly third
the speed compared to when
in the HIGH RANGE position,
leading to an increase in the
engine’s drive power.
