Airb ag sys tem
Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc ­
cupants.
F ig . 118 Side curta in system, driver 's s ide: side curtain a ir­
bag locat ion
T he side curtain airbags are located on both sides
of the inter ior above the front and rear side w in­
dows ~
fig. 118. They a re identified by the word
"A IRBAG" on the windshie ld frame and the cen­
te r roo f pilla r.
The side c urtain airbags contain features that
provide ejection mitigation to help prevent veh i­
cl e occupants or parts o f their bodies from be ing
complete ly or part ially ejected from the veh icle
interior i n certain side impacts and vehicle roll ­
overs.
The side c urtain airbag system supplements the
safety belts and can help to reduce the risk of in­
jury for occupants' heads and upper torso on the s ide of the vehicle that is str uck in a side colli­
sion . The side curtain airbag inflates in side im­
pacts and only when the vehicle acce leration reg­
istered by the control unit is high enough. If this
rate is be low the reference va lue programmed in­
to the control unit, the side curtain airbag will not be t riggered, even though the car may be
badly damaged as a resu lt of the co llision .
It is
not possible to define an airbag triggering range
that w ill cover every possible angle of impact,
since the circumstances w ill vary considerably be ­
tween one collision and another. Important fac-
tors include, for example, the nature (hard or ..,.
131

Airbag system
soft) of the impacting object, the angle of im­
pact, vehicle speed, etc .
q page 132, How side
curtain airbags work.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in position in the event of a collision so
that the side curtain airbags can provide protec­
tion .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­ member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly . This is another reason
why you should always wear your safety belts, not just because the law requires you to do so
q page 106, General information.
It is important to remember that while the side
curtain airbag system is des igned to help reduce
the likelihood of serious injuries, other injuries,
for example, swe lling, bruising, and m inor abra­
sions can also be associated with these airbags.
Remember too, these airbags will dep loy o nly
once and only in certain kinds of accidents -your
safety belts are always there to offer protection .
The side curtain airbag system basically
consists of:
- The electronic control module and external side
impact sensors
- The side curtain airbags above the front and
rear side windows with ejection mitigation fea­
tures
- The airbag indicator light in the instrument
panel
The airbag system is monito red electronically to
make certa in it is fun ction ing properly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnostics) .
The side curtain airbag is not activated:
-if the ignit ion is tu rned off,
- in s ide collisions when the accelerat io n meas-
ur ed by the sensor is too low,
- in rear-end collisions.
132
A WARNING
-Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seating position
~ page 42,
Front seats .
-If the airbag ind icator light q page 14
comes when the veh icle 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.
How side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who are properly re­
strained.
Fig. 119 Il lustratio n of pr inciple: I nflated s ide curta in air ­
bags on t he le ft s ide
The side curtain airbags inflate between the oc­
cupant and the w indows on the side of the veh i­
cle that is struck in a side collision
~ fig. 119.
When the system is triggered, the side curta in
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In order
to help provide this additional protection, the
side curtain airbag must inflate within the blink
of an eye at very high speed and with great force .
The side curtain airbag could injure you if your
seat ing position is not prope r or upright or if
i tems a re located in the area where the supple­
mental sid e cu rtain airbag inflates. This applies
especially to children ~
page 134.
Although they are not a soft pillow, side curtain
airbags can "cush ion" the impact and in this way .,.

Child safety
Advanced Airbags and the weight-sensing mat in the front seat
The Advanced Airbag System in your vehicle de­
tects the presence of an infant or child in a child
restraint on the front passenger seat using the
weight -sensing mat in the seat cushion and the
sensor below the safety belt latch on the front
passenger seat that measures the tension on the
safety belt .
The weight-sensing mat measures total weight
of the child and the child safety seat and a child blanket on the front passenger seat . The weight
on the front passenger seat is related to the de­
sign of the child restraint and its "footprint ", the
size and shape of the bottom of the child re­
straint as it sits on the seat. The weight of a child
restraint and its "footprint" vary for different
kinds of child restraints and for the different
models of the same kind of child restraint of­
fered by child restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard to­
gether with the weight ranges of typical infants
and typical 1 year-old child have been stored in
the control unit of the Advanced Airbag System .
When a child restraint is being used on the front
passenger seat with a typical 1 year-old child, the
Advanced Airbag System compares the weight
measured by the weight sensing mat with the in­
formation stored in the electronic control unit.
The electronic control unit also registers the ten­
sion on the front passenger safety belt. The ten­
sion on the safety belt for the front passenger
seat will be different for an adult who is properly
using the safety belt as compared to the tension
on the belt when it is used to attach a child re­
straint to the seat. The sensor below the latch for
the safety belt for the front seat passenger
measures the tension on the belt. The input from
this sensor is then used with the weight to "de­
cide" , whether there is a child restraint with a
typical 1 year-old child on the front passenger
seat and whether or not the airbag must be
turned off.
136
· Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions . If in exception­
al 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 restraint is correctly recog­
nized by the weight-sensing mat inside 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
differen t weights and si zes 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:

A WARNING 1 = -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­ nering, hydroplaning or peak tract ion charac­
teristics.
A WARNING
The temperature grade for this t ire is estab­
lished for a t ire that is properly inflated and
no t overloaded. Excess ive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(!) General notes
Applies to: veh icles with tire pressure monitoring system
-
Each tire, including the spare (if provided),
should be checked monthly when co ld and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placa rd or
tire i nflat ion pressure label. (If your vehicle has
tires of a different s ize tha n the s ize indicated on
the veh icle placard or tire inflation pressure la­
be l, yo u sh ou ld de termine the prope r tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
eq uipped w ith a tire pressu re monito ring sys tem
(TPMS) that ill uminates a low tire p ress ure te ll­
tale when one or more of your tires is significan t­
l y under-inflated. Accordingly, when the low tire
p ressure tellta le illuminates, you should stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi­
cantly under-i nflated tire causes the tire to over­
h eat and can lead to t ire failure . Unde r-inflation
a lso reduces fuel efficiency and t ire t read life,
Wh eel s
and may affect the vehicle 's handling an d stop ­
ping ability.
Please note tha t the TPM S is not a s ubstitute fo r
prope r ti re maintenance, a nd it is the dr iver's re­
spons ibility to maintain co rrect t ire pressure,
even if under-inflatio n has not reached the level
to t rigge r ill umination of the TPMS low t ire pres­
s ur e te lltale .
Yo ur vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TP MS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfu nction, the telltale w ill flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated . Thi s seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation o f replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lf u nction te lltale after replac ing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lt ernate tires and
wheels allow the TPMS to continue to function prope rly.
' If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles wi th Tire Pressur e Mon ito ring System in·
dicator
The tire pressure indicator in the ins trument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characterist ics of the ind ividu ­
al tires. If the pressure changes in one o r more
whee ls, this is indicated in the inst rument cl uste r
display with t he

dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
