Introduction
The
cruise control driving system is described
on the following pages.
The driving safety systems ABS, BAS and
ESP ®
are described in the “Safety and
security” section (Y page 47). 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 status
indicator of the multifunction display:
R
USA only: e.g. CRUISE 55 Miles
R Canada only: e.g. ¯ 90 Km/h G
Warning!
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.
R The 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.
R The 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.
R Deactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
Warning!
When the cruise control is braking, the brake
pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do

not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others. Driving systems
