Adaptive light control
The concept
Adaptive light control is a variable headlamp
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐
rameters, the light from the headlamp follows
the course of the road.
In tight curves, e.g., on mountainous roads or
when turning, an additional, corner-illuminating
lamp is switched on that lights up the inside of
the curve when the vehicle is moving below a
certain speed.
Activating
Switch position
with the ignition switched
on.
The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
To avoid blinding oncoming traffic, the Adaptive
Light Control does not swivel to the driver's side
when the vehicle is at a standstill.
When driving in reverse, only the turning lamp is
active.
Self-leveling headlights
The self-leveling headlights feature adapts the
light distribution to the contours of the road.
The light distribution is lowered on hilltops to
avoid blinding oncoming traffic and tilted in de‐
pressions to increase visibility.
Malfunction
A Check Control message is displayed.
Adaptive light control is malfunctioning or has
failed. Have the system checked as soon as pos‐
sible.
High-beam Assistant
The concept
When the low beams are switched on, this sys‐
tem automatically switches the high beams on
and off or suppresses the light in the areas that
blind oncoming traffic. The procedure is con‐
trolled by a sensor on the front of the interior
rearview mirror. The assistant ensures that the
high beams are switched on whenever the traffic
situation allows. The driver can intervene at any
time and switch the high beams on and off as
usual.
Activating1.Turn the light switch to .2.Press the button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster lights up.
When the lights are switched on, the
high beams are switched on and off automati‐
cally.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to ad‐
equate illumination, e.g., in towns and cities.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams. Depending
on the version of the system in the vehicle, the
high beams may not switch off for oncoming ve‐
hicles, but may only be dimmed in the areas that
blind oncoming traffic. In this case, the blue in‐
dicator light will stay on.

Switching the high beams on and off
manually▷High beams on, arrow 1.▷High beams off/headlamp flasher, arrow 2.
The High-beam Assistant can be switched off
when manually adjusting the light. To reactivate
the High-beam Assistant, press the button on
the turn signal lever.
System limits Personal responsibility
The high-beam assistant cannot serve as
a substitute for the driver's personal judgment
of when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where this is required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.▷In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on freeways.▷In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Camera
The camera is located near the base of the mir‐
ror.
Keep the windshield in the area behind the in‐
terior rear view mirror clean and clear.
Fog lamps

Airbags
1Front airbag, driver2Front airbag, front passenger3Head airbag4Side airbag5Knee airbagsFront airbags
Front airbags help protect the driver and front
passenger by responding to frontal impacts in
which safety belts alone cannot provide ade‐
quate restraint.
Side airbags
In a lateral impact, the side airbag supports the
side of the body in the chest and lap area.Head airbags
In a lateral impact, the head airbag supports the
head.

Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to keep
the danger of injury to your hands or arms as
low as possible if the airbag is triggered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not cover
with adhesive labels or coverings, and do not
attach holders such as for navigation instru‐
ments and mobile phones.▷Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as jack‐
ets, over the backrests.▷Make sure that occupants keep their heads
away from the side airbag and do not rest
against the head airbag; otherwise, injuries
can occur if the airbags are triggered.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system. This
also applies to steering wheel covers, the
dashboard, the seats, the roof pillars and the
sides of the headliner.◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warnings and information on the airbags are
also found on the sun visors.
Functional readiness of the airbag
system
When the ignition is switch on, the warn‐
ing lamp in the instrument cluster lights
up briefly and thereby indicates the op‐
erational readiness of the entire airbag system
and the belt tensioner.
Airbag system malfunctioning
▷Warning lamp does not come on when the
ignition is turned on.▷The warning lamp lights up continuously.Seite 102ControlsSafety102

When there is a malfunction, have the air‐
bag system checked immediately
When there is a malfunction, have the airbag
system checked immediately; otherwise, there
is a risk that the system does not function as ex‐
pected in the event of an accident despite cor‐
responding severity of the accident.◀
Automatic deactivation of the front
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body.
The front, knee, and side airbag on the front
passenger side are activated or deactivated ac‐
cordingly.
Leave feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀
Child restraint fixing system in the front
passenger seat
Before transporting a child on the front passen‐
ger seat, see the safety notes and instructions
under Children on the front passenger seat.◀
Malfunction of the automatic
deactivation system
When transporting older children and adults, the
front passenger airbags may be deactivated in
certain sitting positions. In this case, the indica‐
tor lamp for the front passenger airbags lights
up.
In this case, change the sitting position so that
the front passenger airbags are activated and
the indicator lamp goes out.
If it is not possible to activate the airbags, have
the person sit in the rear.
To make sure that the occupied seat cushion
can be evaluated correctly▷Do not attach covers, cushions, ball mats or
other items to the front passenger seat un‐less they are specifically recommended by
the manufacturer of your vehicle.▷Do not place any electronic devices on the
passenger seat if a child restraint system is
to be installed on it.▷Do not place objects under the seat that
could press against the seat from below.
Indicator lamp for the front passenger
airbags
The indicator lamp for the front passenger air‐
bags indicates the operating state of the front
passenger airbags.
The lamp indicates whether the airbags are ac‐
tivated or deactivated.
▷The indicator lamp lights up
when a child who is properly
seated in a child restraint fix‐
ing system intended for that
purpose is detected on the
seat or the seat is empty. The
airbags on the front passen‐
ger side are not activated.▷The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
Detected child seats
The system generally detects children seated in
a child seat, especially in the child seats that
were required by NHTSA when the vehicle was
manufactured. After installing a child seat, make
Seite 103SafetyControls103

Page 104 of 243

sure that the indicator lamp for the front pas‐
senger airbags lights up. This indicates that the
child seat has been detected and the front pas‐
senger airbags are not activated.
Strength of the driver's and front
passenger airbag
The strength with which the driver's and front
passenger airbags are triggered depends on the
position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Control
Display.
Calibrating the front seats
A corresponding message appears on the Con‐
trol Display.1.Move the respective seat forward all the
way.2.Move the respective seat forward again. It
moves forward briefly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the message on the Control Display disappears.
If the message continues to be displayed, repeat
the calibration.
If the message does not disappear after a repeat
calibration, have the system checked as soon as
possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury or
damage to objects.◀
FTM Flat Tire Monitor
The concept
The system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected. Therefore, check the tire infla‐
tion pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive wheels,
high lateral acceleration.▷When driving with snow chains.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
