To increase or decrease in 1 mph
increments (Canada: 1 km/h
increments): briefly press the cruise
control lever up 0002for a highe rset speed
or down 0003for a lower set speed.
The set speed appears in the multifunction
display with the 0001DSR symbol. It is also
displayed in status indicator 0023.
When DSR is activated, you can change the
set speed to a value between 1mph and
11 mph (Canada: between 2 km/h and
18 km/h).
i The DSR set speed is always changed in
1 mph increments (Canada: 1 km/h
increments). This is regardless of whether
you press the cruise control lever to or
beyond the pressure point.
Off-road programs (vehicles with the
ON&OFFROAD package) General notes
The off-road programs assist you in driving
off-road. The engine’s performance
characteristics and the gearshifting
characteristics of the automatic transmission
are adapted for this purpose. ABS, ESP
®
and
4ET Sprograms especially adapted to off-road
driving are activated. An accelerator pedal
curve suitable for the terrain is selected, i.e.
the accelerator pedal must be depressed
further to accelerate.
Do not use the off-road programs on roads
that are snow-covered or icy or if you have
mounted snow chains on yourv ehicle.
For information on driving off-road, see
(Y page 187).
The following program messages are shown
in the multifunction display until the
applicable vehicle level is set. Up to off-road
level 2, you can hide the program messages
using the 0007or the 000Bbutton on the
multifunction steering wheel. Off-road program 1

Off-road level 1 is set to +1.2 in (+30 mm)
above the highway level.
If you drive at a speed above 70 mph
(110 km/h), off-road program 1 switches to
AUTO program.
Select off-road program 1 for gentle off-road
terrain, e.g. for gravel or sand surfaces or
tracks. The engine's torque is restricted to a
limited degree and the drive wheels can spin.
The spinning wheels produce acutting effect
for better traction.
You can only activate off-road program 1
when driving at speeds below 60 mph
(100 km/h). The Drive Program OFFROAD 1 Max Speed 60 mph (100 km/h ) message
appears in the multifunction display. 248

Select off-road program 2 for rough terrain,
e.g. for steep and/o rrough terrain or driving
on rocky terrain.
i Your vehicle has an automatically
activated differential lock for the transfer
case. It controls the balance between the
front and rear axles. The differential lock improves the vehicle’s
traction. 4ETS (Y
page 71) controls the
balance between both wheels on an axle.
You can only activate off-road program 2
when driving at speeds below 25 mph
(40 km/h).
LOW RANGE off-road gear (vehicles
with the ON&OFFROAD package) Important safety notes
G
WARNING
If you select the LOW RANGE off-road gear on
a slippery road surface, the wheels could lose
traction:
R if you remove your foot from the
accelerator pedal when driving
R if off road ABS intervenes when braking
If the wheels lose traction. the vehicle can no
longer be steered. There is an increased
danger of skidding and accidents.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces. G
WARNING
If you do not wait for the transfer case gear
change process to complete, the transfer
case could remain in the neutral position. The
power transmission to the driven wheels is
then interrupted. There is a danger of the
vehicle rolling away unintentionally. There is
a risk of an accident.
Wait until the transfer case shift process is
completed.
Do not turn off the engine while changing gear
and do not shift the automatic transmission
to another position. Driving systems

R
Secure any objects on the traile rto prevent
the cargo from slipping when the vehicle is
in motion.
R If you couple up a trailer, regularly check
that the cargo is securely fastened and
make sure that the trailer lamps and (if
applicable) the trailer brakes are
functioning correctly.
R Bear in mind that the handling will be less
stable when towing a trailer than when
driving without one. Avoid sudden steering
movements.
R The vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
R If possible, avoid abrupt braking. Depress
the brake pedal moderately at first, so that
the trailer can activate its own brakes. Then
increase the pressure on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears on uphill or downhill
gradients, shift to a lower gear using the
left-hand steering wheel paddle shifter.
Al ower gear and lower speed reduce the
risk of engine failure.
R When driving downhill, shift to a lower gear
to utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases
dramatically while the air-conditioning
system is switched on, switch off the air-
conditioning system.
Coolant heat can additionally be dissipated
by opening the windows and by setting the
blower fan and the interior temperature to
maximum.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination. Due to the length of your vehicle/trailer
combination, you will have to travel an
additional distance beyond the vehicle you
are overtaking before returning to the
previous lane. Decoupling

WARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overru nbrake
is engaged. G
WARNING
Vehicles with level control:
The vehicle is lowered as soon as you
disconnect the trailer cable. This could result
in yourl imbs or those of other people that are
betwee nthe vehicle body and tires or
underneath the vehicle being trapped. There
is a risk of injury.
Make sure that nobody is in the immediate
vicinity of the wheel housings or under the
vehicle when you disconnectt he trailer cable.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the
rebounding of the overrun brake.
X Make sure that the automatic transmission
is set to position P.
X Apply the vehicle's electric parking brake.
X Start the engine.
X Close all doors and the tailgate.
X Apply the trailer's parking brake.
X Detach the trailer cable and decouple the
trailer.
X Switch off the engine. 258
