High-beam Assistant The concept
When the low beams are activated, this system
automatically switches the high beams on and
off. The procedure is controlled by a camera on
the front of the interior rearview mirror. The as‐
sistant ensures that the high beams are acti‐
vated whenever the traffic situation allows. The
driver can intervene at any time and reel the
high beams on and off as usual.

traffic and traffic driving ahead of you, and to
adequate 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.
Switching the high beams on and off

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.▷When 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
presence of highly reflective signs.▷At low speeds.Seite 90CONTROLSLights90

Functional readiness of the airbag
system
When the ignition is reel 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.
In case of a malfunction have airbag sys‐
tem checked immediately.
In case of a malfunction have airbag system
checked immediately; otherwise, there is a risk
that the system does not function as expected
in case of a severe accident. ◀
Automatic deactivation of the front-
seat passenger airbags
The system reads if the front passenger seat is
occupied by measuring the human body's re‐
sistance.
Front, knee and side airbag on the front pas‐
senger's side are either activated or deacti‐
vated.
Leave feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, proper
functioning of the front passenger airbag might
not be assured. ◀
Child restraint fixing system in the front
passenger seat
Before transporting a child on the front passen‐
ger seat, refer to the safety notes and instruc‐
tions for children on the front passenger seat,
see Children. ◀
Malfunction of the automatic
deactivation system
When transporting older children and adults,
the front-seat passenger airbags may be deac‐
tivated in certain sitting positions. In this case,
the indicator lamp for the front-seat passenger
airbags lights up.
In this case, change the sitting position so that
the front-seat 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 enable correct recognition of the occupied
seat cushion▷Do not attach covers, cushions, ball mats or
other items to the front passenger seat un‐
less they are specifically recommended by
your vehicle's manufacturer.▷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.▷No moisture in or on the seat.
Indicator lamp for the front-seat
passenger airbags

▷The indicator lamp lights up
when a child is properly
seated in a child restraint fix‐
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.▷The indicator lamp does not light up when,
e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags on
the front passenger side are activated.
Detected child seats
The system generally detects children seated in
a child seat, particularly in child seats required
by NHTSA when the vehicle was manufactured.
After installing a child seat, make sure that the
indicator lamp for the front-seat passenger air‐
bags lights up. This indicates that the child seat
has been detected and the front-seat passen‐
ger airbags are not activated.
Strength of the driver's and front-seat
passenger airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passeng‐
er's seat.
With a respective message appearing on Con‐
trol Display calibrate the front seats to keep the
accuracy of this function over the long-term.
Calibrating the front seats
A corresponding message appears on the Con‐
trol Display.
1.Move the respective seat all the way for‐
ward.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, re‐
peat the calibration.
If the message does not disappear after a re‐
peat 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. ◀
Tire Pressure Monitor
TPM
The concept The system monitors tire inflation pressure in
the four mounted tires. The system warns you if
there is a significant loss of pressure in one or
more tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Hints Tire damage due to external factors
Sudden tire damage caused by external
circumstances cannot be recognized in ad‐
vance. ◀
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 172.
Functional requirements
The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.Seite 96CONTROLSSafety96
