— The system has detected a road lane marking on
both the right and left sides of the vehicle.
If the lane keeping system (Lane Assist) is not
available, Emergency Assist is also not availa-
ble.
WARNING
The intelligent technology used in Emergency As-
sist cannot overcome the physical limits specified,
and functions only within the limits of the system.
The driver is always responsible for controlling the
vehicle.
x
Adapt your speed and distance from the vehi-
cles ahead to suit visibility, weather, road and
traffic conditions.
x
Emergency Assist cannot always prevent acci-
dents and serious injuries on its own.
x
If the radar sensor for the Adaptive Cruise Con-
trol (ACC) or the camera for the lane keeping
system are covered or have been displaced,
Emergency Assist may carry out unwanted
brake or steering interventions.
x
Emergency Assist does not react to persons, an-
imals or vehicles crossing or approaching in the
same lane.
WARNING
If Emergency Assist is triggered unexpectedly, it
can result in accidents and serious injuries.
x
If the vehicle behaves differently than expected,
cancel the intervention of Emergency Assist by
braking or steering.
x
Switch off the lane keeping system (Lane As-
sist).
x
Do not use Travel Assist.
x
Go to a qualified workshop and have the system
checked.
Lane change system (Side As-
sist)
Introduction to the topic
The lane change assist system (Side Assist) pro-
vides assistance when checking for traffic be-
hind the vehicle.
Radar sensors monitor the area behind the vehicle.
The system measures the distance and speed differ-
ence in relation to other vehicles and informs the
driver by means of visual signals in the wing mirrors.
System limits
Use the lane change system only on surfaced roads.
The lane change system may interpret the traffic sit-
uation incorrectly in the following driving situations,
for example:
— In tight bends.
— When driving in the middle of two lanes.
— When road lanes are of varying width.
— At crests in the road.
— In poor weather conditions.
— Where there are special roadside structures, e.g.
high or offset crash barriers.
WARNING
The intelligent technology used in the lane change
system cannot overcome the physical limits speci-
fied, and functions only within the limits of the
system. Do not let the increased convenience of
the lane change system tempt you into taking any
safety risks. Always take care when using the lane
change system as you could otherwise cause acci-
dents or injuries. The system is not a substitute for
the full concentration of the driver.
x
Adapt your speed and distance from the vehi-
cles ahead to suit visibility, weather, road and
traffic conditions.
x
Your hands should always be on the steering
wheel so that you can steer at any time.
x
Observe the displays in the exterior mirror
housings and on the instrument cluster display
and act in accordance with the requests.
x
Always pay attention to what is happening
around the vehicle.
x
Never use the lane change system if the radar
sensors are dirty, covered or damaged. These
circumstances can impair the proper function-
ing of the system.
x
It may be hard to see the display in the wing
mirror in direct sunlight.
Some settings can be saved in the user ac-
counts of the personalisation function and can
therefore change automatically when the user ac-
count is changed → page 39.
The radar sensors calibrate themselves once in
the first few kilometres after vehicle delivery
and if the sensors are repaired. The sensor range
may be limited during the calibration phase.
