Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc­
cupants.
Fig. 121 S id e curt ain system, drive r's s ide : side curtain air­
bag locatio n
The side curtain airbags are located on both sides
of the inter ior above the fro nt and rear side win­
dows~
fig. 121. T hey are identified by the word
"AIRBAG" on the windshie ld frame and the cen­
ter roof p illar .
The side curtain airbags contain features that provide ejection mitigation to help prevent veh i­
cle occupants or parts of their bodies from being
completely or part ially ejected from the vehicle
interior in 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
side of the vehicle that is struck in a side coll i­
sion. The side curta in a irbag inflates in side im-
pacts and only whe n the vehicle acce lerat ion .,.

registered by the control unit is high enough . If
this rate is below the referenc e va lue program­
med into the contro l unit, the side curtain airbag
will not be triggered, even though the car may be
badly damaged as a result of the collision. It is
not possible to define an airbag triggering range
that will cover every poss ible a ngle of impact,
since the circumstances will vary considerab ly be­
tween one coll is ion and another. Impo rtant fac­
tors incl ude , fo r example , the nature (ha rd or
soft) of the impacting object , the ang le of im­
pact, vehicle speed, etc .
¢ page 135, How side
curtain airbags work.
Aside from their normal s afety function, safe ty
be lts 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 s ubstitute for yo ur
safety be lt. 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 wear ing it properly . Th is is another reason
why you should always wear your safety belts ,
n ot j ust because the law requires you to do so
¢ page 109, General information .
It is important to remember that while the s ide
curta in a irbag system is des igned to he lp reduce
the likelihood of ser ious injuries, other i njuries,
for example, swel ling, b ruising, and m ino r abra­
sions can a lso be associated w ith these airbags.
Remember too, these a irbags w ill dep loy only
once and only in certa in kinds of acc iden ts -your
safety be lts are always there to offer protection .
The side curtain airbag system basically
con sists of:
- T he elec tronic contro l module and external side
impact sensors
- T he side c urtain airbags above the front and
rea r side windows with ejection mitigation fea ­
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monitored e lectronically to
make certain it is f unct ion ing properly at all
Airb ag sys tem
times. Each time you turn on the ignition, the air­
bag system indicato r light wi ll come on for a few
seconds (self diagnostics) .
The side curtain airbag is not activated :
- if the ignition is turned off,
- in side co ll isions when the accele ration meas-
ured by the sensor is too low,
- in rear-end collisions.
A WARNING
- Safety belts an d the airbag system will only
p rovide protec tion when occupants are in
the proper seat ing position
¢ page 44,
Front seats.
- If the ai rbag ind ic a tor light~ page 14
comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­
posed to, or w ill not inf late when it should.
How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re­
strained .

bags o n the le ft s ide
The side curtain airbags inflate between the oc­
cupant and the w indows on the side of the veh i-

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 chi ld restraint and its "footprint", the
size and shape of the bottom of the chi ld re­
stra int as it sits on the seat. The weight of a child
restraint and its "footp rint" vary for different
kinds o f 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 be ing 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 contro l unit.
The electronic control un it 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 d ifferent fo r an ad ult who is properly
using the safety belt as compared to the tension
on the belt when it is used to attach a chi ld re­
straint to the seat. The sensor below the latch for
the safety belt for the front seat passenger measures the tens ion on the belt. The input from
this sensor is then used with the weight to "de­
cide", whether there is a child restraint w ith a
typical 1 year-old child on the front passenger
seat and whet her o r not the a irbag must be
turned off.
Ch ild safety
Child restraints and Advanced Airbags
Regardless of the ch ild restraint that you use,
make s ure tha t it has been cer tified to mee t Safe­
ty Standards and has been cert ified by its manu­
facturer for use with an airbag. Always be sure
that the c hild 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
t ion on child safety and Advanced A irbags and
heed all of the applicable WARNINGS . Make cer­
ta in that the ch ild restraint is correctly recog­
nized by the weight-sensing mat ins ide the front
passenge r seat, that the front passenge r 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 restra ints have
been avai lab le over the years, new models are in­
t roduced regu larly incorporating new and im­
proved designs and older models are taken out of
production. Child restraints are not standardized.
Child restra ints of the same type typically have
different weights and sizes and different 'foot­
pr ints,' the size and shape of the bottom of the
ch ild rest raint that sits on the seat, when they
are installed on a vehicle seat. These d ifferences
make it virt ua lly impossib le to certify comp liance
wi th the requi rements for advanced a irbags w it h
each and every child restraint tha t has ever been
sold in the past or wi ll be so ld over the course of
the usefu l life of your vehicle .
For t his reason, the Uni ted States N ation al High­
way Traffic Sa fety Administration has published a
list of specific type, makes and mode ls of chi ld
restraints that must be used to certify compli­
ance of the Advanced Airbag System in your vehi­
cle w ith the suppress ion requirements of Federal
Motor Vehicle Safety Standard 208 . These child
restra ints are:

and may affect the vehicle's handling and stop­ p ing ability .
Pl ease no te that the TPMS is not a substi tute for
p roper tire maintenance, and it is the drive r's re ­
sponsib ility to maintain cor rect tire pressure,
even if under-inflation has not reached the leve l
to tr igger illum inat ion of the TPMS low tire pres ­
sure telltale.
Your vehicle has also been eq uipped with a TPMS
mal funct ion indicator to indicate when the sys ­
tem is not operating properly. The TPMS mal­
function indicator is combined w ith the low tire
pressure tellta le. Whe n the system detects a
malfunct ion, the telltale will flash for approx i­
mately one min ute and then remai n cont inuo usly
i llum inated. This sequence will continue upon
s ubseq uen t ve hicl e start- ups as long as the m al­
f u nction ex ists.
When the malfunct io n in dicator is ill uminated,
the system may not be ab le to detect or signa l
l ow tire press ure as intended . TPM S malfu nctions
may oc cur for a var iety of reasons, incl uding the
installation of replacement or alternate ti res o r
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to cont inue to funct ion
p roperly.

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.
(D Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
