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 trig‐
gered.▷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 navi‐
gation instruments and mobile phones.▷Make sure that the front passenger is sit‐
ting 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
jackets, 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
hearing 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;
otherwise, 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 explo‐
sives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or
undesired 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
warning lamp in the instrument cluster
lights up briefly and thereby indicates
the operational 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 103SafetyControls103

When there is a malfunction, have the
airbag 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
expected in the event of an accident despite
corresponding 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
accordingly.
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 pas‐
senger seat, refer to the safety notes and in‐
structions under Children on the front passen‐
ger seat.◀
Malfunction of the automaticdeactivation system
When transporting older children and adults,
the front passenger airbags may be deacti‐
vated in certain sitting positions. In this case,
the indicator lamp for the front passenger air‐
bags 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
unless 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
passenger side are not acti‐
vated.▷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.Seite 104ControlsSafety104
Online Edition for Part no. 01 40 2 909 928 - VI/13
Detected child seatsThe 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 sure that the indicator lamp for the front
passenger airbags lights up. This indicates that the child seat has been detected and the
front passenger 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 Con‐
trol Display.
Calibrating the front seats A corresponding message appears on the
Control 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 disap‐
pears.
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.◀
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; other‐
wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
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.1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.
