Airbags
1Front airbag, driver2Front airbag, front passenger3Head airbag4Side airbag5Knee airbagFront 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 airbag
In a lateral impact, the side airbag supports the
side of the body in the chest and lap area.
Head airbag In a lateral impact, the head airbag supports
the head.Seite 136ControlsSafety136
Online Edition for Part no. 0140 2 964 330 - VI/15
Ejection MitigationThe head airbag system is designed as an
ejection mitigation countermeasure to reduce
the likelihood of ejections of vehicle occupants
through side windows during rollovers or side
impact events.
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.
Information for optimum effect of the
airbags
WARNING
If the seat position is incorrect or the de‐
ployment area of the airbags is impacted, the
airbag system cannot protect as intended or
cause additional injuries due to triggering.
There is risk of injuries or danger to life. Ob‐
serve the Information for optimum protective
effect of the airbag system.◀▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim. Hold 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 trig‐
gered.▷Make sure that the front passenger is sit‐
ting correctly, i.e., keeps his or her feet and
legs in the floor area.▷Make sure that occupants keep their heads
away from the side airbag.▷There should be no persons, animals or
objects 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.▷Do not apply adhesive materials to the air‐
bag cover panels, do not cover them or
modify them in any way.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not specifically suited for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as
jackets, over the backrests.▷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.▷Do not remove the airbag system.
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.
Warnings and information on the airbags are
also found on the sun visors.
Functional readiness of the airbag
system
Information WARNING
Individual components can be hot after
triggering of the airbag system. There is risk of
injuries. Do not touch individual components.◀
WARNING
Improperly executed work can lead to
failure, malfunction or unintentional triggering
of the airbag system. In the case of a malfunc‐
tion, the airbag system could not trigger as in‐
tended in the event of an accident despite re‐

spective accident severity. There is risk of
injuries or danger to life. Have the airbag sys‐
tem checked, repaired, dismantled and scrap‐
ped by a dealer’s service center or another
qualified service center or repair shop.◀
Correct function When drive readiness is switched on,
the warning lamp in the instrument
cluster lights up briefly and thereby in‐
dicates the function readiness of the entire air‐
bag system and the belt tensioners.

Automatic deactivation of the front-
seat passenger airbags
The concept 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.
Information 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.
WARNING
The ensure the front-seat passenger air‐
bag function, it must be detected, whether a
person occupies the front passenger seat. The
entire seat cushion area must be used for this
purpose. There is risk of injuries or danger to
life. Make sure that the front passenger keeps
his or her feet in the floor area.◀
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 determined to
be safe for use on the front passenger
seat.▷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 airbag in the roofliner indicates the operat‐
ing state of the front-seat passenger airbag.
The lamp indicates whether the airbags are ei‐
ther activated or deactivated.
After drive readiness is switched on, the lamp
briefly lights up and then indicates whether the
airbags are either 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.Seite 138ControlsSafety138
Online Edition for Part no. 0140 2 964 330 - VI/15
▷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 WARNING
There is risk of jamming when moving
the seats. There is risk of injuries or risk of
property damage. Make sure that the area of
movement of the seat is clear prior to any ad‐
justment.◀
A corresponding message appears on the
Control Display.
1.Press the switch and move the respective
seat all the way forward.2.Press the switch 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.
Intelligent Safety The conceptIntelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent a imminent collision.▷Front-end collision warning with braking

Collision warning with
braking function
The concept The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The system is controlled using a camera.
If the vehicle is equipped with Active Cruise
Control with Stop & Go function, ACC, theSeite 140ControlsSafety140
Online Edition for Part no. 0140 2 964 330 - VI/15
front-end collision warning is additionally con‐
trolled via the cruise control radar sensor.
Active Protection: if a collision seems to be un‐
avoidable, PreCrash functions are triggered.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. Time of
warnings may vary with the current driving sit‐
uation.
Detection range
It responds to objects if they are detected by
the system.

Brake and increase distance.Symbol flashes red and an acoustic
signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneu‐
ver.
Prewarning
This warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a relatively high dif‐
ferential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by an automatic braking intervention
in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Brake intervention, City braking
function
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise is sufficiently quick and hard stepping
on the brake pedal.
The system can additionally assist possibly
with automatic braking intervention if there is
risk of a collision.
At low speeds the vehicle can be decelerated
to a complete stop.
The braking intervention takes place up to ap‐
prox. 50 mph/80 km/h.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
With radar sensor and Active CruiseControl: braking intervention

to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise is sufficiently quick and hard stepping
on the brake pedal.
The system can assist with automatic braking
intervention if there is risk of a collision.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
