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 the parking
brake is being tested on a brake test
dynamometer. 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.
LOW RANGE mode
The LOW RANGE mode is available on
vehicles with enhanced off-road package.
In the following situations you should switch
to the LOW RANGE mode:
R
during off-road driving
R
before driving through water
R
when towing up or down on steep gradients
With LOW RANGE selected, the engine’s
power delivery and the shifting behavior of
the automatic transmission are adjusted.
Furthermore, the ABS, the ESP
®
, and the
4-ETS functions especially adapted to off-
road travel are activated.
For more information on off-road driving, see
“Off-road driving” (Y page 262).
For information on driving safety systems
during LOW RANGE mode, see “Driving safety
systems” (Y page 61).
Gear ranges
There are two possible settings.
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
vehicle travels at roughly
third the speed compared to
when in HIGH RANGE
position, leading to an
increase in the engine’s
drive power.
G
Warning!
Always wait until the procedure of shifting
from HIGH RANGE to LOW RANGE – and from
LOW RANGE to HIGH RANGE – has been
entirely completed. During this procedure do
not turn off the engine or shift the automatic
transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
Please observe related messages appearing
in the multifunction display.
