Hill-start assist system

Warning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the parking brake in addition
to shifting the automatic transmission into
park position P.
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.

Rear-axle level control
The rear-axle level control adjusts the vehicle
level for the rear axle. The rear-axle level
control is beneficial because it keeps the
vehicle level at the rear axle constant,
independent of the load.

AIRMATIC
The AIRMATIC lets you select the chassis and
suspension setup. The chassis and
suspension setup adjusts the damping
behavior and the ride height for your vehicle.
The AIRMATIC consists of two components.
The Adaptive Damping System (ADS)
(Y page 153) and the vehicle level control
(Y page 154).
Adaptive Damping System (ADS)
The
Adaptive Damping System (ADS) is
controlled electronically and operates
continuously. It adjusts the damping
characteristics to the current operating and
driving conditions. The damping is adjusted
individually for each wheel. Driving safety and
tire comfort are increased.
The fine tuning of the damping is dependent
on:
R
your driving style
R
road surface conditions
R
your personal settings
The following settings are available:
