To increase or decrease in 1 mph
increments (Canada: 1 km/h
increments): briefly press the cruise
control lever up :for a higher set speed
or down ;for a lower set speed.
The set speed appears in the multifunction
display with the ÃDSR symbol. It is also
displayed in status indicator =.
When DSR is activated, you can change the
set speed to a value between 1 mph 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

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
4ETS programs 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 your vehicle.
For information on driving off-road, see
(Y page 197).
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 %or the abutton on the

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 a cutting effect
for better traction.

Select off-road program 2 for rough terrain,
e.g. for steep and/or rough 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 72) controls the
balance between both wheels on an axle.
You can only activate off-road program 2
when driving at speeds of 25 mph (40 km/h)
or below.
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

accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the
equipment when the vehicle is stationary. When telephoning, you must observe the
legal requirements for the country in which
you are currently driving.
