Principle
Drive-off support provides the best possible
traction when driving off in certain situa-
tions, e.g., on difficult surfaces like snow or
sand.
Hill Descent Control is a downhill control
feature for vehicles with all-wheel drive.
This feature adjusts the vehicle speed on
steep downhill gradients, e.g., when driving
on unpaved roads.
This function ensures maximum drive
power at low speeds with adapted driving
stability.
When Hill Descent Control is on, the vehi-
cle moves at the speed set by the driver,
without the driver having to depress the
brake pedal.
Activating/deactivating the drive-
off support
To activate drive-off support, go through
the menu as follows: Apps menu /
"Vehicle" / "Driving settings" / "Drivetrain
and chassis" / "Activate drive-off support
once".
While Hill Descent Control is adjusting the
speed, the system automatically distributes
the brake power to the individual wheels.
Driving stability and steerability are im-
proved. If necessary, the Antilock Braking
System prevents the wheels from locking.
Hill Descent Control can be enabled at
speeds below approx. 25 mph/40 km/h.
Drive-off support remains on until it is de-
activated or the driving mode is changed.
Speeds can be set between ap-
prox. 2 mph/3 km/h and approx.
Display
20 mph/30 km/h. While driving downhill,
this system reduces the vehicle speed to the
set value, as physically possible.
If drive-off support is activated, the
drive-off support indicator light illu-
minates on the Interaction Unit.
Hill Descent Control provides assistance
when driving in selector lever positions D,
N, and R.
ALL4
Vehicle features and options
ALL4 is the vehicle's all-wheel-drive sys-
tem. The interplay between ALL4 and other
suspension control systems, e.g., Dynamic
Stability Control, further optimizes vehicle
traction and driving dynamics.
This system may not be available in the
owned vehicle, e.g. due to the selected op-
tional equipment, the national-market ver-
sion or the option for later enabling and
software updates. This also applies to indi-
vidual functions of the system.
ALL4 variably distributes the drive force to
the front and rear axles as required by the
driving situation and road conditions.
For information on whether a function is
currently available in the vehicle or when
the function can be installed in the vehi-
cle, contact an authorized service center or
another qualified service center or repair
shop.
