Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed.
The maximum speed can be set at
speeds above 25 km/h up to
200 km/h.
The driver can only accelerate up to

Exceeding the speed limit
When exceeding the limited speed
without driver input, the speed will
flash in the Driver Information Centre
and a chime sounds during this
period.
In the event of an emergency, it is
possible to exceed the speed limit by
depressing the accelerator pedal
firmly nearly to the final point. In this
case no chime appears.
190Driving and operatingaccident, consult a workshop to
verify and adjust the radar unit
position.
Settings
A vehicle message and chime
reminds the driver to drive off when
the adaptive cruise control holds the vehicle at standstill. This function
named Go Notifier can be activated
and deactivated in the vehicle
personalisation menu in the Info
Display.
Vehicle personalisation 3 123.
Fault
If the adaptive cruise control does not
work due to temporary conditions
(e.g. blockage by ice, overheated
brakes or low speed manoeuvres) or if there is a permanent system error,
a message is displayed in the Driver
Information Centre.
Vehicle messages 3 122.
Forward collision alert
The forward collision alert is part of
the forward collision system 3 123. It
can help to avoid or reduce the harm
caused by front-end crashes.
A vehicle ahead is indicated by the
control indicator A.
Additionally, the status of the forward
collision alert is indicated on the
Driver Assistance page in the Driver
Information Center 3 111.
If the vehicle is equipped with
conventional cruise control, the
forward collision alert uses the front
camera in the windscreen to detect a
vehicle directly ahead, in your path.
If the vehicle is equipped with
adaptive cruise control, the forward
collision alert uses the radar sensor
and front camera to detect a vehicle
directly ahead, in your path.
Forward collision alert with front
camera detects vehicles to distances
of approx. 60 m and operates
automatically at all speeds above
walking speed.Forward collision alert with radar
sensor detects vehicles to distances
of approx. 150 m and operates
automatically at all speeds above
walking speed.
Activation
A precondition is that forward collision
alert in the vehicle personalisation
menu is not deactivated 3 123.
Alerting the driver The vehicle ahead control indicator
A illuminates green in the instrument
cluster when the system has detected
a vehicle in the driving path. On
vehicles with head-up display, A is
projected on the windscreen.
The control indicator A changes to
amber when the distance to a
preceding moving vehicle gets too
small.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
198Driving and operatingFront pedestrian protection includes:● detecting front pedestrian ahead
● front pedestrian alert
● automatic braking
Detecting front pedestrian ahead
A pedestrian ahead up to a distance
of approx. 40 m is indicated by the
control indicator 7 in the instrument
cluster. On vehicles with head-up
display, 7 is projected on the
windscreen.
Front pedestrian alert
When approaching a detected
pedestrian too quickly, the collision
alert symbol pops up in the Driver Information Centre and the pop-upsymbol 7 in the head-up display is
projected on the windscreen in the
driver's field of view. A warning chime is provided. The brake system may
prepare for driver braking to occur
more rapidly which can cause a brief, mild deceleration. Continue to apply
the brake pedal as required.
Cruise control or Adaptive cruise
control may be disengaged when the
Front pedestrian alert occurs.
Automatic braking If a crash into a pedestrian directly
ahead is imminent, and the brakes
have not been applied, Automatic
braking may automatically brake
moderately or brake hard. This can
help to avoid some very low speed
pedestrian crashes or reduce
pedestrian injury.
Automatic braking levels may be
reduced under certain conditions,
such as higher speeds.If this happens, automatic braking
may engage the Electric parking
brake to hold the vehicle at a stop.
Release the parking brake. Pressing
the accelerator pedal will also release Automatic braking and Electric
parking brake 3 171.
This system includes Intelligent brake
assist, and the Emergency automatic braking system may also respond to
pedestrians.
Active emergency braking 3 194.
Automatic braking can be disabled in
the vehicle personalisation menu
3 123.
General information9 Warning
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
Driving and operating219Note
The system is switched off during
detection of ambiguous lane
markings, e.g. in construction areas.
Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Activation
The lane keep assist is activated by
pressing a. The LED in the button
illuminates to indicate that the system
is switched on.
When the control indicator a in the
instrument cluster or in the head-up
display illuminates green, the system
is ready to assist.
The system is operational at vehicle
speeds between 60 km/h and
180 km/h and if lane markings are
available.
The system gently turns the steering
wheel and the control indicator a
changes to yellow, if the vehicle
approaches a detected lane marking
without using the turn lights in that
direction.
The system alerts by flashing a
together with three chimes, from the respective direction, if the lane is
departed significantly.
The system is only operable when a
lane marking is detected.
If the system only detects lane
markings on one side of the road, it
will only assist for this side.
Lane keep assist detects hands-free
driving. In this case a message in the
Driver Information Centre pops-up
and a chime sounds as long as lane
keep assist detects hands-free
driving.
Indication on Driver Assistance page
If the system is active but one or both
lanes are not detected, they appear
as a line of hollow dashes, as shown
on the right side of the vehicle in the
graphic above.
Vehicle care275UnderbodySome areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check the underbody and have it waxed if
necessary.
Bitumen / rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.
Air shutter Clean the shutter system in the front
bumper to maintain correct
functionality.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
