Rear parking system
Descript ion
Applies to vehicles: wit h rear park ing system
The rear parking system is an audible parking
aid .
Desc ripti on
There is a sensor in the rear bumper cover. If
these detect an obstacle, aud ible signals warn
you .
Make sure the sensors are not covered by
sticke rs, deposits or any other obstructions as
it may impa ir the sensor function. For infor­
mat ion on cleaning, see
¢ page 170.
The range at which the sensors begin to meas­
ure is approximately :
s ide 3
ft (0.90 m)
rear
center 5.2 ft (1.60 m)
The closer you get to the obstacle, the sho rter
the interval between the audib le signa ls . A
continuous tone sounds when the obstacle is
less than approximate ly 1 foot (0.30 meters)
away. Do not cont inue back ing up¢ .&.

& WARNING
If, in exceptional c ircumstances, you mus t
install a forwa rd -facing child restraint on
the front passenger's seat:
- Always make sure the forward -fac ing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up aga inst or very near the inst ru­
ment pane l.
- Always move t he passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away f rom
the a irbag as poss ible, before insta lling
the fo rward-facing child restraint. T he

Advanced Airbag System components
The fron t passenger seat in your vehi cle has a
l ot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sens ing mat, sensors, wiring, brack­
ets, and mo re. 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 unit mon itors the Advanced Air­
bag System and tur ns the a irbag indicator
light on when a ma lfu nction in t he system
components is de tected. The func tion of the
a ir bag ind icator light is described in greater
detai l below . Because t he front passenge r
Airbag sys tem 119
seat contains important parts of the Ad ­
vanced Airbag System, you must take care to prevent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from do ing its job in
a crash.
The front Advanced Air bag System
consists of the following:
- Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to prov ide info rmat ion to the Adva nced Ai r­
bag System about the sev erity of the crash .
- An elect ronic control unit, with integrated
crash sensors fo r front and s ide impacts.
The control u nit "decides" whether to fi re
t he front a irbags based on t he informat io n
received from t he crash sensors. The con trol
unit also "decides" whe ther the sa fety belt
pretensioners sho uld be activated.
- An Adv anced A irbag w it h gas gene ra tor and
cont ro l valve fo r the d river inside the steer ­
ing wheel h ub.
- An Advance d Airbag w ith gas generator and
contro l valve inside the inst rument pane l for
the front passenger .
- A wei ght -sensing mat unde r the upho ls tery
padding of the front passenge r seat cushion
that measures the total weight on the seat .
The informat ion reg istered is sent continu­
ously to the electronic control unit to regu­
late deployment of the front Advanced Air­
bag on t he passenger side.
- An airbag monitoring system and ind icator
light in the instr ument cluster¢
page 123.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steer ing whee l or inst rument panel. The i n­
formation register ed is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
ployment o f th e front Adva nced A irbags .

& WARNING
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the front passenger and driver seat wi ll pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by q ualified 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 information 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
t h e a irbag sys tem from wo rking proper­
ly .
-
- Never p lace seat covers or rep lacement
upho lstery that have not been specifica l­
ly approved by Audi on the front seats.
- Seat
covers can prevent the Advanced
Airbag System from recognizing chi ld re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly.
- Never use cushions, pillows, blankets or similar items on the front passenger
seat. T he additional padding w ill prevent
the we igh t-sensing mat in the sea t from
accurately regis tering the child rest rain t
or pe rson on the seat and prevent the
Advanced Airbag System from function­ ing p roperly.
- If you m ust use a child restraint on the
front passenge r seat and the child re­
straint manufacture r's instructions re­
quire the use of a towel, foam cushion or
someth ing 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
s traint is i nstalled on the front passen­
ge r seat.
- If the PASSENGER AIR BAG OFF light
does not come on and st ay on, immed i­
ately install child rest raint in a rear seat­
ing position and have the ai rbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide a irbags supp lement the protect ion of­
fered by the front three-point safety belts
with pretensioners and load limiters a nd the
adjus table head rest rain ts to help reduce the
r isk of in jury in a wide range of accident and
c rash situations . Be s ure to read the impor ­
tant information about safety and heed the
WARNINGS in this chapter .
Deployment o f the Adv a need A irbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured

The Advanced Airbag System as we ll as the
side airbags and side c urtain airbags with
ejection mitigation features (including the
e lectronic control un it, sensors and system
wiring) a re all monitored continuously to
make sure that they are func tioning properly

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and sent to the electronic co ntrol
u ni t. Some suspension changes can, for exam­
p le, increase the fo rce levels measured by the
se nsors and make the airbag system deploy in
crashes in w hich it would not dep loy i f the
changes had not been made. Other kinds of
changes may reduce the force levels meas ­
ured by the sensors and prevent the airbag
from deploying when it should.
A WARNING
Changing the vehicle's s uspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag pe r­
formance and increase the risk of ser ious
personal in jury in a crash.
- Never install suspe nsion components
t ha t do not have the same per fo rman ce
c h arac ter istics as the componen ts or igi­
nally insta lled on your vehicle .
- Never use ti re -r im combi nat ions tha t
h ave not been approved by A udi.
A WARNING
-
Items s tored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­ tro l modu le and prevent the Advanced A ir­
bag System from work ing properly.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig . 1 21 Side a irbag locat ion in the driver's seat
The side airbags are located in the sides of the
front seat backrests<=)
fig. 121 facing the
doo rs . They are identified by the word "AIR­
BAG".
The side airbag sy stem bas icall y consi st s of :
- t he ele ctron ic cont rol modu le and external
side impact sensors
- the two a irbags located in the s ides of the
front backrests
- t he airbag warning ligh t in the instrument
cluste r.
The airbag system is monitored electronically
to make ce rtain that it is f unctioning properly
at all times. Each time you turn on the ig ni­
tion, the airbag syst em ind icator light will
come on for a few seconds (se lf diagnostics).
The side airbag system supplements the safe­
ty belts and can help to red uce the risk of in­
jury to the driver's and front passenger's up­ per to rso on the s ide of the vehicle that is
str uck in a s ide collis ion. The ai rbag deploys
on ly in side impac ts and only when the vehicle
acce le ration reg istered by the cont ro l unit is
high enough. If this rate is be low the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
IJJ-

128 Airbag system
though the car may be badly damaged as a re ­
sult of the collision . It is not possible to de­
f ine an a irbag tr igger ing range that will cover
every possible angle of impact, since the cir­
cumstances will vary considerably between
one collision and another . Important facto rs
include, for example, the nature (hard or soft)
of the impacting object, the ang le of impact,
vehi cle speed, etc. ¢
page 129, Important
safety instructions on the side airbag system.
As ide from the ir normal safety function, safe­
ty belts work to he lp keep the driver or front
passenger in position in the event of a side
coll is ion so th at the side a irbags can provide
protection.
The airbag system is
not a substitute for your
safety be lt. Rather, it is pa rt of the overall oc ­
cupant restraint system in your ve hicle. Al­
ways remember that the side 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 a lways wear
your safety belts, not just because the law re­
quires you to do so¢
page 104, General
notes .
It is important to remember that while the
supplemental s ide a irbag system is designed
to reduce the like lihood of serious injur ies,
other injuries, for example, swell ing, bruising,
and minor abras ions can also be associated
with deployed side a irbags . Remember too,
side ai rbags w ill deploy on ly once and o nly in
cer tain k inds of accidents -yo ur sa fe ty belts
a re a lways there to offer protect ion .
Vehicle damage, repair costs or even the lack
of veh icle damage are not necessar ily an indi­
cation of over-sensi tive or failed a irbag activ a­
tion. In some co llisions, both fron t and s ide
airbags may inflate. Remember too, that air­ bags will deploy only once and only in certain
kinds of collisions -your safety belts are al­
ways there to offer protection in those acci­
dents in which airbags are not supposed to
deploy or when they have already deployed .
The side airbag sy ste m will not depl oy :
- when the ignition is turned off - in side co
llisions when the accelera tion
meas ured by the sensor is too low
- in front -end collisions
- in rear -end collisions
- in rollove rs .
In some types of accidents the front airbags,
s ide curtain airbags and s ide a irbags may be
trigge red together .
_&. WARNING
-
-Safety b elts and th e airbag system w ill
only provide prote ction when occupa nts
are in the proper seating position
9 page 129.
- If th e ai rbag ind icator light ¢page 16
comes when the veh icle is being used,
have the system inspected immediately
by your authorized A udi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained.
F ig. 122 In flated side a irbags o n left s ide of veh icle

When the system is triggered, t he a irbag is
filled with propellant gas and b reaks through
a seam in the seat su rface area ma rked "AIR ­
BAG".
It expands between the side trim panel
and the passenger . In order to help provide
t hi s additional protect ion, the side airbag
must inflate within a fraction of a second at
very h igh speed and with great force . The sup­
plementa l side airbag could injure you if your
seat ing pos ition is not proper or upright or if ..,.

always be repaired immediately by an au­
thorized Aud i deale r.
- If children are seated improperly, their
risk of injury increases in the case of an
acc ident ~
page 133, Child Safety .
-Never attempt to modify any compo­
nents of the airbag system in any way .
- In a side collision, s ide a irbags will not
function properly if sensors cannot cor ­
rectly measure increasing air pressu re in­
side the doors when air escapes thro ugh
larger, unclosed openings in the door
pane l.
- Never drive with inter ior door trim pan­
els removed.
- Never drive when parts have been re­
moved from the ins ide door panel and
the openings they leave have not been
properly closed.
- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly
closed .
- Always make certa in that openings are
covered or filled if additional speake rs
or other equ ipment is installed in the
ins ide door panels.
- Always have work on the doors done by
an author ized Audi dealer or qualif ied
wo rkshop.
Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fig . 123 S ide curta in s ystem, d river 's s ide: side curt ain
airbag locat io n
The side curta in airbags are located on both
s ides of the interior above the front and rear
s ide windows ~
fig. 123. They are identified
by the word "AIRBAG" on the windshield
frame and the center roof pillar .
The side curta in airbags conta in featu res that
provide ejection mitigation to help prevent ve­
hicle occupants or parts of their bod ies from
being comp letely o r partia lly ejected from the
vehicle interior in certai n side impa cts and ve­
hicle rollovers.
The side curtain airbag system supplements
the safety belts and can help to red uce the
risk of in jury for occ upants ' heads and uppe r
torso on the side of the vehicle that is struck
in a side collision. The side curtain a irbag in­
flates in side impacts and only when the vehi­ cle acceleration registered by the control unit
is h igh enough . If this rate is below the refer­
ence value programmed into the con trol unit,
the side curta in a irbag w ill not be tr iggered,
even though the car may be badly damaged as
a resu lt of the co llision .
It is not possib le to
define an airbag triggering range that w ill
cover every possib le ang le o f impac t, since the
c ircumstances will va ry considerably between
one collision and another. Important factors
incl ude, for example, the nature (hard or soft)
of the impacting object, the angle of impact, ""
