Airbag system

Monitoring the
Advanced Airbag System

‘oring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the ka light and
the PASSENGER AIR BAG OFF light.
The Advanced Airbag System as well as the side
airbags and side curtain airbags with ejection
mitigation features (including the electronic con-
trol unit, sensors and system wiring) are all
monitored continuously to make sure that they
are functioning properly whenever the ignition is
on. Every time you turn on the ignition, the air-
bag system indicator light ka will come on fora
few seconds (function check).
The system must be inspected when the
indicator light Ba:
— does not come on when the ignition is switched
on,
— does not go out a few seconds after you have
switched on the ignition, or
— comes on while driving.
If an airbag system malfunction is detected, the
indicator light will come on to serve as a constant
reminder to have the system inspected immedi-
ately.
If a malfunction occurs that turns the front air-
bag on the passenger side off, the PASSENGER
AIR BAG OFF light will come on and stay on
whenever the ignition is on.

ZA\ WARNING
An airbag system that is not functioning prop-
erly cannot provide supplemental protection
in a frontal crash.
- If the airbag indicator light > page 238
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.

PASSENGER AIR BAG OFF light


B8V-0215

Fig. 218 Center console: passenger airbag off warning
light
The PASSENGER AIR BAG OFF light is located in
the center of the instrument panel > fig. 218.
The PASSENGER AIR BAG OFF light will come on
and stay on to tell you when the front Advanced
Airbag on the passenger side has been turned off
by the electronic control unit. If the bulb for the
PASSENGER AIR BAG OFF light burns out, the
airbag indicator light 2 will come on to signal a
malfunction in the Advanced Airbag System. Al-
though the burned-out bulb will not change the
way the front passenger's frontal airbag works, it
will no longer be possible to use the PASSENGER
AIR BAG OFF light to make sure that the airbag
on/off status is correct for the occupant on the
front passenger seat. Have the airbag system in-
spected immediately by your authorized Audi
dealer.
The PASSENGER AIR BAG OFF light will blink
for about 5 seconds when:
— the ignition is switched on and
— the capacitive passenger detection system,
which switches the front seat passenger's fron-
tal Advanced Airbag on and off, detects a
change in the status of the front passenger
seat.
As soon as the PASSENGER AIR BAG OFF light
stops blinking, always make sure that the airbag
status
(on or off) as shown by the PASSENGER
AIR BAG OFF light is proper for the age, size and
electrical capacitance of the person occupying
the front passenger seat. Always make sure that
the safety belt for the front passenger seat is
properly fastened.

Child safety

Safety Standards and has been certified by its
manufacturer for use with an airbag. Always be
sure that the child restraint is properly installed
at one of the rear seating positions. If in excep-
tional circumstances you must use it on the front
passenger seat, carefully read all of the informa-
tion on child safety and Advanced Airbags and
heed all of the applicable WARNINGS. Make cer-
tain that the child and child restraint are correct-
ly recognized by the capacitive passenger detec-
tion system in the front passenger seat, that the
front passenger airbag is turned off, and that the
airbag status is always correctly signaled by the
PASSENGER AIR BAG OFF light.
Many types and models of child restraints have
been available over the years, new models are in-
troduced regularly incorporating new and im-
proved designs and older models are taken out of
production. Child restraints are not standardized.
Child restraints of the same type typically have
different
weights and sizes and different “foot-
prints”, the size and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each and every child restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your vehicle.
For this reason, the United States National High-
way Traffic Safety Administration has published a
list of specific type, makes and models of child
restraints that must be used to certify compli-
ance of the Advanced Airbag System in your vehi-
cle with the suppression requirements of Federal
Motor Vehicle Safety Standard 208. These child
restraints are:
Subpart A - Car bed child restraints
Subpart B - Rear-facing child restraints

Storing new tire pressures
Applies to: vehicles with tire pressure monitoring system
The tire pressure specifications must be stored
correctly for the tire pressure monitoring system
to function reliably.
It is always necessary to store the tire pressures
when the tire pressures are modified, for exam-
ple due to a change in load or when new sensors
are installed.
> Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci-
fied values and are adapted to the load
=> page 330, fig. 260. Only correct and store
the pressure in tires whose temperature is ap-
proximately the same as the ambient tempera-
ture. If the temperature of the tire is higher
than the ambient air temperature, the tire
pressure must be increased approximately
3.0 PSI (0.2 bar) above the value on the sticker.
» Switch the ignition on.
> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Service &
checks > Tire pressure monitoring > Store tire
pressure > Yes, store now. After storing the tire
pressures, the tire pressure monitoring system
measures the current pressures while driving
and stores them as the new specified pressures.
> If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximately 10 minutes so that the sen-
sor signal from the wheels is received again.


During this adaptation phase, --.-- is displayed
for the pressure and temperature and the tire
pressure monitoring system is only partially
available. It only provides a warning if one or
more tire pressures is below the minimum per-
mitted specified pressure.
If the @ indicator light turns on and the mes-
sage Tire pressure: wheel change detected.
Please check all tires and store pressures in
MMI also appears, the system has detected that
the position of the sensors has changed because
of a tire rotation, or that new sensors were instal-
led. Store the new tire pressures.

ZX WARNING
Read and follow the important information
and notes > page 339.
Malfunctions
Applies to: vehicles with tire pressure monitoring system

If the tire pressure monitoring system is not
available, the a indicator light appears in the
instrument cluster display along with the mes-
sage Tire pressure: malfunction! See owner's
manual.
If the ia indicator light appears after switching
the ignition on or while driving and the @ indi-
cator light also blinks for approximately one mi-
nute and then stays on, there is a system mal-
function. The following are examples of situa-
tions that could cause a malfunction:
— If the message appears at the end of the adap-
tation phase, the system may not detect one or
several of the wheel sensors necessary for pres-
sure monitoring. This may result from one or
more wheels without wheel sensors or with in-
compatible wheel sensors being installed.
—Awheel sensor or another component has
failed.
— Using snow chains can affect the function of
the system because of the shielding effect of
the chains.
— The tire pressure monitoring system is not
available due to a malfunction.
— Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunction due to
the strong electromagnetic field.
The ia indicator light and the message turn off
once the tire pressure monitoring system is avail-
able again. If you cannot correct the malfunction
and the ia indicator light stays on, drive imme-
diately to an authorized Audi dealer or author-
ized Audi Service Facility to have the malfunction
repaired.

Accessories and technical changes

Usually maintenance and repair work requires
special tools, measuring devices, and other
equipment that is available to trained vehicle
technicians in order to help ensure that your vehi-
cle and all of its systems operate correctly, relia-
bly, and safely. Performing work on the vehicle
incorrectly can impair the operation and reliabili-
ty of your vehicle and may void one or more of
your vehicle's warranties.
Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.
