▷Arrows: at least one lane marking was de‐
tected and warnings can be issued.
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 missing, worn, poorly visi‐
ble, merging, 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 is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.
Hints 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 acci‐
dents are still possible despite all warnings.◀

Commission regulations. Operation is gov‐
erned by the following:
FCC ID:▷NBG009014A.
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.
Brake force display
The concept
▷During normal brake application, the outer
brake lights light up.▷During heavy brake application, the inner
brake lights light up in addition.
Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:
▷Attentiveness assistant.▷PreCrash▷PostCrash
Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, e.g., on highways. In this situation, it is recommended that the driver
takes a break.
Note Personal responsibility
The system cannot act as a substitute for
the personal assessment of one's physical
state and may not detect an increasing lack of
alertness or fatigue or may not detect it cor‐
rectly. Therefore, make sure that the driver is
rested and alert; otherwise, risks may be de‐
tected too late and an accident be caused as a
result.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
After travel has begun, the system is trained
about the driver, so that increasing lack of
alertness or fatigue can be detected.
This procedure takes the following criteria into
account:
▷Personal driving style, e.g., steering behav‐
ior.▷Driving conditions, e.g., length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.

HintsSufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
culated-air mode; otherwise the air quality in
the interior continuously deteriorates and win‐
dow condensation increases.◀

The automatic climate control achieves this
temperature as quickly as possible, if needed
by using the maximum cooling or heating li‐
dacity, and then keeps it constant.
Do not rapidly switch between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
AUTO program
Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐
ces, the air is directed to the windshield, side
windows, upper body, and into the footwell.
The cooling function, refer to page 147, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.
Intensity of the AUTO program
With the AUTO program activated, the auto‐
matic intensity control can be changed.
Press the left or right side of the but‐
ton: decrease or increase the inten‐
sity.
The selected intensity is shown on the display
of the automatic climate control.
Convertible program

your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar,
or hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.If the headlights do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the
service center check this.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. Have the head‐
lights' settings checked and corrected by serv‐
ice after a replacement.
