Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, a lways:
• Adjust the driver's seat and steering wheel
properly ¢
page 164,
• Adjust the front passenger's seat properly
r=; page 75,
• Wear safety be lts properly ¢ page 176,
• Always properly use the proper child re-
straint to protect children¢
page 203.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplemental airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenger to sit prope rly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag can inflate fully and
comp letely and provide supp lemental protec­
tion in ce rtain frontal collisions¢

There is a lot that the driver and the passen­
gers can and must do to help the individua l
safety features installed in your A udi work to­
gether as a system.
Proper seat ing pos ition is important so that
the front airbag on the driver s ide can do its
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals , or if you
have concerns with regard to the function or
operation of the Advanced Airbag System ,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
lations at 1-800-822-2834 fo r poss ible modi­
ficat ions to your veh icle.
When the airbag system deploys, a gas gener ­
ator will f ill the a irbags, break open t he pad­
ded cove rs, and inflate between the steering
whee l and the dr iver and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immediately after dep loy­
ment so that the front occupants can see
t h rough the windshie ld again witho ut inter­
ruption .
All of th is takes p lace in the b link of an eye, so
fast that many peop le don't even realize tha t
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their w ay when they deploy.
Front airbags in combination with properly
worn safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and front seat pas­
senger from hitting pa rts of the inside of the
vehicle while reducing the forces acting on the
occupant during the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. A irbags do not
protect the arms or the lower parts of the
body.
Both front airbags wi ll not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle dece lerat ion rate
caused by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
t rol unit , the airbags will not be trigge red,
even though the car may be badly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of ve hicle damage
is not necessari ly an indication of whether an
airbag shou ld inflate or not .

Since the circums tances will vary considerab ly
between one collision and another , it is not
possible to define a range of veh icle speeds
that will cover every possible k ind and angle
of impact t hat w ill always t rig ger the a irbags .
Important factors include, for example, the
nature (hard or so ft) of the object which the
car h its, the ang le of impact, vehicle speed ,
etc. The front airbags will a lso not inflate in
side or rear collisions, or in ro ll-overs .
Alw ays rememb er: Airbags will deploy only
once, and only in certa in kinds of co llisions.
Your safety belts are always there to offe r pro­
tect ion in those s ituations in which airbags
are not supposed to deploy , or when they have
a lready deployed ; for example , when your ve­
hicle strikes or is struck by another vehicle af­
ter the first co llision .
This is just one of the reasons why an a irbag is
a supp lementary restraint and is not a s ubsti ­
tute for a safety belt . The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts ¢
page 173.
A WARNING
Sitting too close to the steer ing whee l or
instrument panel will dec rease the effec­
tiveness of the airbags and will inc rease
the risk of pe rsonal injury in a co llision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instr ument pan­
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the steer ing whee l, investi­
ga te whethe r adaptive equipment may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
flates -even with an Advanced Airbag.
A irbag system 183
-To reduce the risk of injury when an air­
bag inflates, always wear safety belts
properly ¢
page 177, Safety belts.
-Always make certain that ch ild ren age 12
or younger a lways ride in the rear seat. If
children are not properly restrained, they may be severe ly inju red or killed when an
airbag inf lates .
- Never let ch ildren ride unrestra ined or
improperly restrained in the vehicle. Ad ­
just the front seats prope rly .
- Never ride with the back rest reclined .
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 164.
-Always sit upright with your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the f loor in front of the seat to
he lp preven t serio us in ju ries to the legs
and h ips if the airbag infla tes.
- Never recline the front passenger 's seat
to transport objects . Items can a lso
move into the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sud den maneuve r. Obje cts near the air ­
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING
Airbags that have de ployed in a crash must
be replaced.
- Use on ly orig inal equipment airbags ap­
proved by Aud i an d installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
place any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never perm it salvaged or recycled air­
bags to be installed in your vehicle . •

Child restraints on the front seat - some
important things to know
• Be sure to read the important information
and heed the WARNINGS for important de­
ta ils about ch ildren and Advanced Airbags
i=> page 203.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all children, especially those 12 years and
younger, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld safety seat. It
can be a very dangerous place for a n infan t or
a child in a rearward -facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comply with the require­
men ts of United States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your ve hicle was manufact ured.
The Standa rd requires the fron t air bag on t he
passenger side to be turned off ("sup­
p ressed") if a ch ild up to about one yea r of
age restrained in one of the rear-facing or for­
ward-facing infant restraints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re ­
straints that we re used to certify compliance

The PASSENGER AIR BAG OFF light in the in­
strument panel tells you when the front Ad­
vanced A irbag on the passenger side has been
turned off by t he e lectronic control unit.
Each t ime you tur n on the ignition, the
PAS ­
SENGER AIR BAG OFF
li ght will come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occupied
- will stay on if there is a small child or child
restraint on the front passenger seat -
w ill go off i f the front passenger seat is oc ­
cupied by an adult as registere d by the
weight -sensing mat
r::!) page 193, Monitor­
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
when the control unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off .
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
c hi ld b ut less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on, the
front a irbag on the passenger side has not
been turned off by the elect ronic con trol unit
and can deploy if the control uni t se nses an
impact that meets the cond itions stored in its
memory .
For exampl e, the airbag may deploy if:
- a small ch ild that is heav ie r th an a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is in one of
the child safety seats listed
r::!) page 205), or
- a child who has outgrown ch ild restraints is
on t he front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
li ght does not illum inate and stay lit) even if a
small ad ult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- re cli ned ba ck res t w it h thei r feet on the

If t he fron t passenger a irbag dep loys, the
F ede ra l St andard req uires the airbag to meet
the "low risk" dep loyment criteria to red uce
the risk of injury t hro ugh interactio n wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions ..,_

Always remember, a chi ld safety seat or infant
carrier installed on the front seat may be
struck and knocked out of position by the rap ­
id ly inflating passenger's airbag in a frontal
coll is ion . The airbag cou ld greatly reduce the
effectiveness of the child restraint and even
seriously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for children -when properly
restra ined accord ing to their age and si ze - we
strongly recommend that children always sit in the back seat¢
page 203, Child Safety.
A WARNING
A child in a rearward-facing child safety
seat insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
t he fron t airbag inf lates - even with an Ad­
vanced Airbag System .
- The inflating a irbag w ill hit the child
sa fety seat or infant carrier w it h great
f orce and w ill smash the ch ild safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rear -facing child sa fety
seats on the rear seat.
- If you mus t install a rearward facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENGER AIR BAG O FF
light does not come on and stay on, im­
med iately install the rear-facing child
safety seat in a rear seating posit ion and
have the a irbag system inspected by you r
authori zed Aud i dealer.
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfere with the deployment of the air­
b ag and cause serious person al injury to
the ch ild .
WARNING
If, in exceptional c ir c umstances, you mus t
install a forwa rd -facing child restra int on
the front passenger's seat:
A irbag system 185
-Always ma ke sure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
wit h a passenger front and s ide a irbag.
- Never put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost position in t he seat's fore and
aft adj ustment range, as fa r away from
the airbag as possible before installing
the forward-fa cing ch ild restra int. The
backrest mu st be a dju ste d to an upright
posi tion.
- Ma ke sure that the

A WARNING
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light wi ll be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed ¢
page 193, Monitoring the Ad­
vanced Airbag System .
-Take t he chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the

- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and serious ly injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­

Your veh icle is equipped with an "Advanced
A irbag System" in complia nce w ith United
States Federal Motor Vehicle Safety Standard
( FM VSS) 208 as app licab le at the time your
veh icle was manufactured. The safety belts f
or the seats have "pretensioners" that help
to take slack out of t he belt system . The pre­
tens ioners are also act ivated by the electronic
control unit for the airbag system.
T he front safety be lts also have load limiters
to help reduce the forces applied to the body
i n a crash .
T he airbag for the drive r is in the stee ring
whee l hub ¢
fig. 208 and the airbag for the
front passenger is in the instr ument panel
~ fig. 209 . The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you nee d to know about the ai r­
bags in your vehicle . We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
P lease be sure to heed the WARNINGS -they
are extremely importa nt for your safety and
the safety of you r passengers, especially in­
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alo ne for p rotection.
- E ven w hen they deploy, airbags provide
only supplement al pro tectio n.
- Airbag work most effect ive ly when used
with p roperly wor n safety bel ts.
- Therefore, always wea r you r safety belts

h icle is properly res trained.
_&. WARNING
A pe rso n on the fron t passenger seat, es­
pe cial ly infa nts and sm all ch ildren, w ill re­
ceive serio us inju ries and can even be kil-
l ed by being too close to the airbag when
it inflates .
- A lthough t he Advanced Airbag System in

conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
ployment are met.
- Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant restraint system in your vehicle .
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right, wearing your safety belt and wearing it
properly. This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle
has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in-
Airbag system 187
jury through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard
~ page 205, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re­
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com­
pliance with the US Safety Standard
~page 205,
-weight less than a thresho ld level stored in
the control unit is detected on the front pas­
senger seat .
When a person is detected on the front pas ­
senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­ quires the front airbag to be turned off . If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory. ..,. •
•

188 Airbag sys tem
If the tota l weight on the front passenger
seat is more than that of a typical 1 year-o ld,
but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy (the
PASSENGER AIR BAG OFF light does not
come on).
For e xample , the airbag m ay deploy if :
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld safety seats listed
¢ page 205),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument pane l w ill come on and stay
on.
The front airb ag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not ill uminate and stay lit) if:
- a small adu lt o r teenager is o n the front pas­
senger se at
- a passenger who is not sitt ing upr ight w it h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenge r seat .
I f the front passenge r airbag deploys, the
F ederal Standa rd requires the airbag to meet
the " low ris k'' deployment criter ia to help re ­
d uce the risk of inj ury through interaction
with the airbag. "Low risk" deployment occurs
in those crashes that take place at lower de ­
celerations as defined in the electronic control un it.

Always remember: Even tho ugh yo ur vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impor­
tant information i n the sect ions that follow

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more . The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on .
The control un it mon itors the Advanced Air ­
bag Sys tem and turn s the a irbag i ndica tor
light on when a ma lfunction in t he system
components is detected . The function of the
airbag indicator light is described in greater
deta il below. Because the front passenger
seat contains important parts of the Ad­
va nced A irbag System, you must take care to
prevent it from being damaged . Damage to
the seat may p revent the Advanced A irbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle accelera tion/decele ra ti on
to provide info rm ation to the Advanced Air ­
bag System abo ut the severity of the crash.
A irbag system 189
-An elect ron ic cont ro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to f ire
the front a irbags based on the informat ion
received from the crash sensors. The control
unit also "decides" whether the safety belt
prete nsione rs shou ld be act iva ted.
- An Advanced A irbag w it h gas generator for
the driver inside the steering wheel hub .
- An Advanced A irbag w ith gas generator in­
side the instrument pa nel for the front pas­

- Improper repair or disassembly of the
front passenger and driver seat will pre­
vent the Advanced A irbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight­
sensing mat in the passenger seat is
punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Ai r­
bag System under the passenge r seat
cou ld be damaged, prevent ing them and
the airbag system from wo rking proper­
ly .
- Never place seat covers or replacement upholstery that have not been specifical­
ly approved by A udi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploy ing prop­
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the ch ild restra int
or person on the seat and prevent the
Advanced Airbag System from function­ ing properly .
-If you must use a child restra int on the
front passenger seat and the ch ild re- straint manufacturer's instructions
re­
qu ire the use of a towel, foam cushion or
something e lse to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the ch ild re·
straint is installed on the front passen­
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll child restrain t in a rear seat­
ing position and have the airbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supplement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of inju ry in a wide range of accident and
crash situations. Be s ure to read the impor ­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash .
When the electronic control unit registers a low severity crash and the safety belt is being
used, the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat· er t ime in the crash sequence.
If the electron ic control unit registers a crash
of medium severity, the first stage of the air ·
bag deploys followed by the second stage at a
much later time in the crash sequence· re·
gard less of whether the safety belt is being
u sed o r not . In higher sever ity crashes as reg­
iste red by the electronic control unit, both the ..,.

first and second stages deploy almost at the
same time.
On the passenger side, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amo unt programmed in the electronic control
un it. The front airbag on the passenger side
w ill also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recog nized on the seat . The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell
you when the front Advanced Airbag on the passenger side has been t urned off

_&. WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
flates -even with an Advanced Airbag

front airbags
F ig. 210 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro ­
vide supplemental protection in a fronta l col­
l ision.
A irba g sy stem 191
The front airbags are designed to provide ad ­
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upant is properly seated as far as poss i­
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan­
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re­
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air ­
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air­
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
