Driving systems
Introduction
This section describes the following driving
systems of your vehicle:
RCruise control
RHill-start assist system
RAll-wheel drive (4MATIC)
RDynamic handling package with sport
driving mode
RParktronic system, Canada only
RRear view camera
The driving safety systems ABS, Adaptive
Brake, BAS, EBP and ESP® are described in
the “Safety and security” section
(Y page 60).
Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the
multifunction display for approximately
5 seconds. The corresponding cruise control
speed segments : from the selected speed
to the vehicle maximum speed in the
multifunction display are illuminated.
GWarning!
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
RThe use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
RThe use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
RDeactivate the cruise control when driving
in fog.
