When you approach a curve the system may
briefly report vehicles in the next lane due to the
bend of the curve. If the system decelerates you
may compensate it by briefly accelerating. After
releasing the accelerator pedal the system is re‐
activated and controls speed independently.
Driving off
In some situations, the vehicle cannot drive off
automatically; for example:
▷ On steep uphill grades.
▷ In front of bumps in the road.
In these cases, step on the accelerator pedal.
Weather
The following restrictions can occur under unfav‐
orable weather or light conditions:
▷ Poorer vehicle recognition.
▷ Short-term interruptions for vehicles that are
already recognized.
Examples of unfavorable weather or light condi‐
tions:
▷ Wet conditions.
▷ Snowfall.
▷ Slush.
▷ Fog.
▷ Glare.
Drive attentively, and react to the current traffic
situation. If necessary, intervene actively, for in‐
stance by braking, steering or evading.
Malfunction
Radar sensor
The system cannot be activated if the radar sen‐
sor is not aligned correctly. This may be caused
by damage incurred, for instance during parking.
A Check Control message is displayed if the sys‐
tem fails.
Have the system checked by a dealer's service
center or another qualified service center or re‐
pair shop.
The system may be impaired when the detection
range of the radar sensor is partially covered
such as by the license plate holder.
Camera
The function for detecting and responding when
approaching stationary vehicles may be limited in
the following situations:
▷ During calibration of the camera immediately
after vehicle delivery.
▷ If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Steering and traffic jam
assistant
Concept
The system assists the driver in keeping the ve‐
hicle within the lane. For this purpose, the sys‐
tem executes supporting steering movements,
for instance when driving in a curve.
General information
The system determines the position of the lane
markings and the vehicle driving ahead using five
radar sensors and a camera.
Depending on the speed, the system orients it‐
self according to the lane markings or vehicles in
front.
