174Driving and operatingBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 106.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off, the system performs
a self-test which may be audible.
Control indicator u 3 107.
Adaptive brake light During full braking, all three brake
lights flash for the duration of ABS
control.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Driving and operating185It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
vehicle speed increases or decreases
to follow the vehicle in front, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store and maintain speeds over approx.
25 km/h. If following a vehicle ahead
driving slower than 25 km/h, the
slower speed will be set. On vehicles
with automatic transmission, the
system can also brake to a stop.
Adaptive cruise control uses a radar
sensor to detect vehicles ahead. If no
vehicle is detected in the driving path, the adaptive cruise control will
behave like a traditional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal or clutch pedal has been
depressed once after switching on
ignition.
Adaptive cruise control is mainly
advised to be used on long straight
roads like highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 110, m 3 110,
C 3 110.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the cancel
switch have priority over any
adaptive cruise control operation.
Switching on
Press C to switch on adaptive cruise
control. The control indicator m in the
instrument cluster illuminates white.
Additionally C appears in the Driver
Information Centre.
Activation by setting the speed
Adaptive cruise control can be
activated between 25 km/h and
180 km/h.
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
maintained. Control indicator m in the
instrument cluster illuminates green.
Driving and operating2079Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding area
behind and around the vehicle
before reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted between the
number plate lights and has a viewing angle of 130°.
Due to the high position of the camera
the rear bumper can be seen on the
display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in 1 metre intervals projected on
the picture to define the distance to
shown objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.

Warning symbols are indicated as
triangles 9 on the picture which show
obstacles detected by the rear
sensors of the advanced parking
assist.
Additionally 9 appears on the top line
of the Info-Display with the warning to
check the vehicle surrounding.
Deactivation
The camera is deactivated when a certain forward speed is exceeded or
if reverse gear is not engaged for
approx. 10 seconds.

Fault
Fault messages are displayed with a 9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
● The surrounding is dark.
● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The tailgate is not closed correctly.
● The vehicle is towing a trailer. ● The vehicle had a rear end accident.
● There are extreme temperature changes.Rear cross traffic alert
Additional to the rear view camera
3 206 , rear cross traffic alert warns of
cross traffic from left or right side
when driving rearwards. When cross
traffic is recognized and the rear view
camera is activated, a warning
triangle with a direction arrow K
appears on the Colour-Info-Display,
showing the direction of the traffic.
Furthermore, three beeps will sound
from the speaker on the respective
side.
The radar distance sensors are
located sideways in the rear bumper.
