SafetyVehicle features and op‐
tions
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 to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
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.

Ejection Mitigation
The head airbag system is designed as an ejec‐
tion 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 hints 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 sitting
correctly, i.e., keeps his or her feet and legs
in the floor area and does not support them
on the dashboard.
▷There should be no persons, animals or ob‐
jects 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 fully ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary hear‐
ing 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‐
Seite 102CONTROLSSafety102
Online Edition for Part no. 01 40 2 964 571 - X/15
Page 103 of 246

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 passen‐
ger seat, refer to the safety notes and instruc‐
tions 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 un‐
less 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 passenger
airbags indicates the operating state of the
front-seat passenger airbags.
Seite 103SafetyCONTROLS103
Online Edition for Part no. 01 40 2 964 571 - X/15
Page 104 of 246

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,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
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.
To maintain the accuracy of this function over
the long-term, calibrate the front seats as soon
as a relevant Check Control message is dis‐
played. A message also appears on the Control
Display.
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 adjustment.◀
An appropriate Check Control message is dis‐
played.
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 Check Control message 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.
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.
Information
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 182.
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.
