SafetyVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due tothe selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Airbags
1Front airbag, driver2Front airbag, front passenger3Side airbag4Knee airbagsFront airbags
Front airbags help protect the driver and front
passenger by responding to frontal impacts in
which safety belts alone would not provide ad‐
equate restraint.
Side airbags
In a lateral impact, the side airbag supports the
side of the body in the chest, lap, and head
area.Knee airbag
The knee airbag supports the legs in a frontal
impact.
Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.Seite 96ControlsSafety96

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 risk of injury to your hands or
arms as low as possible when the airbag is
triggered.▷There should be no person, 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.▷Dashboard and windshield on the front
passenger side must stay clear - do not at‐
tach adhesive labels or coverings and do
not attach brackets or cables, e. g., for GPS
devices or' 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
might occur when front airbag is activated.▷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; otherwise, inju‐
ries might occur when airbag is activated.▷Do not remove the airbag system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, do not 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, and the seats.◀
Even when you follow all instructions very
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.
Malfunction, deactivation and after de‐
ploying the airbags
Do not touch the individual components imme‐
diately after the system has been triggered;
otherwise, you may risk burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
the service center or an authorized repair shop
for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or
unintentional activation of the airbag - both
may lead to injury.◀
Warnings and information on the airbags are
also found on the sun visors.
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 air‐
bag might not be assured.◀
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 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
unless 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 for the front-seat passen‐
ger airbags indicates the operating state of the
front-seat passenger airbags.
The lamp indicates whether the airbags are ei‐
ther activated or deactivated.
▷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 re‐
quired by NHTSA when the vehicle was manu‐ factured. After installing a child seat, make
sure that the indicator lamp for the front-seat
passenger airbags lights up. This indicates
that the child seat has been detected and the
front-seat passenger 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
Control Display.1.Press the reel and move the respective
seat all the way forward.2.Press the reel forward again. The seat still
moves forward slightly.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.◀
Rollover protection system The concept
The rollover protection system is automatically
activated in the event of a sufficiently serious
accident or if the longitudinal axis is tilted ex‐
cessively. The safety frames located behind
the rear headrests extend within fractions of a
second.
Supplementing the reinforced front windshield
frame, the rollover protection system further
increases passenger safety.
Hints Keep the movement area unobstructed
Always keep the movement area of the
rollover protection system clear. Otherwise,
there may be damage or injuries when the roll‐
over protection system is triggered.◀
Do not place any objects on the covers of the
rollover protection system.
In the event of malfunctions, deactivation
or after deployment
Only have the airbags checked, repaired or dis‐
mantled and the system scrapped by your
service center. Non-professional attempts to
service the system could lead to failure in an
emergency or unintentional activation of the
airbag - both may lead to injury.◀
Triggered rollover protection system After deployment or damage
After deployment of the rollover protec‐
tion system or in the event of damage, have
the system checked and replaced.
Have this work performed only by your service
center; otherwise, this safety feature might not
work properly.◀
