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.▷Make sure that occupants keep their heads
away from the side airbag.▷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.▷There should be no persons, animals or
objects between an airbag and a person.▷Do not apply adhesive materials to the air‐
bag cover panels, do not cover them or
modify them in any way.▷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 use the cover of the front airbag on
the front passenger side as a storage area.▷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 the ignition is switched 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.
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 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 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.
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
and tire temperature.
Information With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 196.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation 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
ensure that the system will operate properly.

pathway lines
▷The static, red turning radius line shows
the space needed to the side of the vehicle
when the steering wheel is turned all the
way.▷The variable, green pathway line assists
you in assessing the amount of space ac‐
tually needed to the side of the vehicle.
The lane line depends on the engaged
gear and the current steering angle. The
track line is continuously adjusted for the
steering wheel movement.
"Parking aid lines"
Turning circle and pathway lines are displayed.
System limits
A Check Control message is displayed when a
camera is not working.
Side View The concept
Side View provides an early look at cross traffic
at blind driveways and intersections. Road
users concealed by obstacles to the left and
right of the vehicle can only be detected rela‐
tively late from the driver's seat. To improve
the viewing, each camera, front and rear on the
vehicle, detects the traffic area on the side.
Which camera is active is shown on the top
edge of the screen.
Information The images of the cameras are displayed, de‐
pending on the gear selected, on the Control
Display.
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic and vehicle surroundings
closely and actively interfere in the respective
situations.◀
