Changing the speed
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed when the
road is clear.▷Each time the rocker switch is pressed to
the resistance point, the desired speed in‐
creases or decreases by 1 mph/1 km/h.▷Each time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi‐
mum of 5 mph/10 km/h.
Hold the rocker switch in position to repeat the
action.
Distance WARNING
The system does not relieve from the
personal responsibility. Due to the system lim‐
its, braking can be late. There is risk of acci‐
dents or risk of property damage. Be aware to
the traffic situation at all times. Adjust the dis‐
tance to the traffic and weather conditions and
maintain the prescribed safety distance, possi‐
bly by braking.◀

Displays in the Head-up Display
With Active Cruise control, some system infor‐
mation can also be displayed in the Head-up
Display.
The symbol is displayed on the Head-
up Display if the set desired speed is
reached.
Distance information The symbol is displayed when the dis‐
tance from the vehicle traveling ahead
is too short.
The distance information is active under the
following circumstances:
▷Active Cruise Control switched off.▷Display in the Head-up Display selected,
refer to page 126.▷Distance too short.▷Speed greater than approx.
40 mph/70 km/h.
System limits
Speed range The system is best used on well-constructedroads.
The minimum speed that can be set is
20 mph/30 km/h.
The maximum speed that can be set is
115 mph/180 km/h.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Deceleration
The system also does not decelerate in the fol‐
lowing situations:
▷For pedestrians or similar slow-moving
road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.Seite 173Driver assistance systemsControls173

Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed.
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
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 deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.

Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Radar sensor
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:▷OAYARS3-A
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:
▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
The desired speed is also maintained downhill,
but may not be maintained on uphill grades if
engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO drive mode, the ve‐
hicle may drop below the set desired speed in
some situations, e.g. on uphill grades.
Information WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:
▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀

The concept
The system assists the driver in keeping the vehicle within the lane. For this purpose, the
system steers independently, e.g., when driv‐
ing in a curve.
Depending on the speed, the system orients it‐
self according to the lane markings or vehicles
in front.

General information
The system determines the position of the
lane markings and the vehicle driving ahead
using five radar sensors and a camera.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
In order to be able to use the system, place
your hands around the steering wheel.
The system is deactivated if the steering wheel
is no longer being touched.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
