General information
The congestion assistant determines speed
and distance from the vehicle in front via a ra‐
dar sensor and the position of the lane marking
via a camera.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
The system is deactivated as soon as contact
with the steering wheel is no longer detected.
In order to be able to use the Congestion As‐
sistant, place your hands around the steering
wheel.
When driving with gloves or with protective
covers, contact with the steering wheel cannot
be detected by the sensors. The system in this
case cannot be used.
Notes Personal responsibility
The system does not relieve the driver of
the responsibility to adapt his or her speed,
distance and driving style to the traffic condi‐
tions. Drive attentively, and react to the current
traffic events. Intervene actively when neces‐
sary, e.g., by braking, steering or making an
evasive maneuver, otherwise, there is danger
of an accident.◀

System limits
When driving within narrow driving lanes, e.g.,
in construction zones or rescue lanes, the sys‐
tem cannot be activated or meaningfully used.
Limited detection capacity
Because of the limits to the detection ca‐
pacity of the camera and the sensor, you
should be alert at all times so that you can in‐
tervene actively, if necessary; otherwise, there
is the danger of an accident occurring.◀
Complying with country-specific laws
When the Congestion Assistant is used,
observe specific national laws.◀
Cruise control
The concept The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:
▷On curvy roads.Seite 139Driving comfortControls139

▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

When ECO PRO is activated, cruise control is
also set to a driving style that saves on fuel
consumption.
