covered, especially when their heads are

Lane departure warningThe concept Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. Depending
on the country-specific version of the vehicle,
the speed is between 35 mph/55 km/h and
45 mph/70 km/h. If the system is switched on
below this speed, a message appears in the in‐
strument cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Notes Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel, as you may lose control of the vehi‐
cle.◀

▷Arrows: at least one lane marking was de‐

Issued warning
If you leave the lane and if a lane marking has
been detected, the steering wheel begins vi‐
brating.
If the turn signal is set before changing the
lane, a warning is not issued.
End of warning
The warning ends:
▷Automatically after approx. 3 seconds.▷When returning to your own lane.▷When braking hard.▷When using the turn signal.
System limits
The system may not be fully functional in the
following situations:
▷In heavy fog, rain or snowfall.▷In the event of worn, poorly visible, merg‐
ing, diverging, or multiple lane markings
such as in construction areas.▷When lane markings are covered in snow,
ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by
objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.▷During calibration of the camera immedi‐
ately after vehicle shipment.Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights
up dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.
Notes Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise an
accident is still possible despite all warnings.◀

Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving in bends.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.

Control
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.

Personal responsibility
The indicator and warning lamps do not
relieve the driver of the responsibility to adapt
his or her desired driving speed and style to
the traffic conditions.◀
The vehicle symbol lights up orange:
A vehicle has been detected ahead of
you.
The vehicle symbol flashes orange:
The conditions are not adequate for
operating the system.
The system was deactivated but applies the
brakes until you actively assume control by
pressing on the brake pedal or accelerator.
The vehicle symbol flashes red and an
acoustic signal sounds:
You are requested to intervene by
braking or making an evasive maneuver.
Displays in the Head-up Display The information from Active Cruise Control
can also be displayed in the Head-up Display.
Adjusting the Head-up Display, refer to

System limits
Speed range
Best results are achieved when using the sys‐
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h to 110 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 driving ahead of you
for instance might not be detected.
Seite 140ControlsDriving comfort140
Online Edition for Part no. 01 40 2 909 774 - VI/13
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.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane,
e.g., a vehicle at a red traffic light or at the end
of traffic congestion.
The system also does not respond to:▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Stationary objects.▷Cross traffic.▷Oncoming traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle. You must react yourself; otherwise,
there is the danger of an accident occurring.◀
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
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 necessary. You must react yourself;
otherwise, there is the danger of an accident
occurring.◀
Unexpected lane change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehi‐
cle, you yourself must react, as the system
does not react to stopped vehicles.
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly in the curve, although
curves cannot be anticipated in advance.
Therefore, drive into a curve at an appropriate
speed.

Adapting the desired speed
Adapt the desired speed to the road con‐
ditions and be ready to brake at all times; oth‐
erwise, there is the danger of an accident oc‐
curring.◀
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 if the road is
clear.
▷Each time the rocker switch is pressed to
the point of resistance, the desired speed
increases or decreases by approx.
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.
Max. adjustable speed: 140 mph/230 km/h.▷Pressing the rocker switch to the resist‐
ance point and holding it there accelerates
or decelerates the vehicle without requiring
pressure on the accelerator. After the
rocker switch is released, the vehicle main‐
tains its final speed. Pressing the switch
beyond the resistance point causes the ve‐
hicle to accelerate more rapidly.
Resuming the desired speed
Press the button.
The stored speed is reached and maintained.
