Sensors are located in the front and rear bump­
ers . If t hese detect an obstacle , audible and visu­
al signa ls warn you.
Make sure the sensors are not covered by stick­
ers, deposits or any other obstructions as it may
impair the sensor function. Fo r information on
cleaning, see

A WARNING
When extending and retracting the rear spoil­
er, make sure there are no persons or objects
w ith in the spoiler range to reduce the risk of
injury .
A WARNING -
Driv ing at higher speeds w ithout the rear
spoiler dep loyed can impa ir hand ling cha rac­
ter istics, mak ing the veh icle h arder to con­
trol.
- Always make sure that the spoiler is de ­
ployed whe n driving at speeds ove r 85 mp h
(140 km/h) . If the rear spoiler warning/indi ­
cator lig ht in the instrument cluster comes
on, the rear spoi ler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed .
Have the spoiler inspected as soon as possi­
ble by an author iz ed Audi dealer or qualif ied
workshop.
- Always obey speed limits and other traffic
laws .
@ Note
-Never push on the vehicle on the rear spoi l­
er . T his cou ld cause damage.
- To prevent damage to the rear spoiler do not lean or p lace anyt hing on it.
- Only operate t he rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
(D Tips
Clean the rear spoi ler compartment every 2 to
3 months . To function correctly, the rear
spoiler must be free of ice, snow and leaves.

Energy management
The starting ability is optimized
T he energy management sys tem manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventional energy sys ­
tem is not driven for a long time, the veh icle bat­
tery is drained by equ ipment (for example, the
i mmob il izer). I n certa in circumstances, there
could may not be enough energy to start the en ­
gine.
Your vehicle is equipped with an intell igent ener­
gy management system fo r dist ributing elect rici­
ty. Thi s sign if icantly improves the start ing ab il ity
and increases the vehicle battery life .
The energy management system Is made up of
battery dia gno sis , idling current management ,
and dynamic energ y m ana gement .
Battery di agnosis
T he battery diagnos is determines the vehicle bat ­
tery cha rge level. The sensors detect the batte ry,
t h e battery cur rent, and the battery temperature .
The current cha rge level and the pe rformance of
t h e ve hicle battery are dete rm ined based on th is.
Idling current management
The idling current management decreases the
energy used while parked . With the engine
switched off , it ma nages the ene rgy distr ib ution
to the d ifferent e lectr ica l components . Data from
t h e battery d iagnosis is ta ken into a ccou nt for
t hi s.
Depend ing on the vehicle batte ry cha rge level,
electr ical eq uipme nt is switched off one item af ­
te r th e o ther to p revent the veh icle bat tery from
dra ining and to ma intain the starting ab ility.
Dynamic energy manag ement
While driv ing , dynam ic energy management dis­
t ributes the app ropr iate amo unt of energy to t he
electr ical eq uipme nt.
It contro ls the batte ry

Airbag syste m
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag S ystem con sists
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The control unit also "de ­
c ides" whether the safety belt pretens ioners
shou ld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer ing
whee l hub.
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A capacitive passenger detect io n system under­
neath t he front passenger seat cover. This sys­
tem measures the elect rical capac ita nce of the
person in the seat. The info rm ation registe red
is sent continuous ly to the e lectronic control
unit to regulate deployment of the front Ad ­
vanced Airbag on the passenger side .
- An airbag monitoring system and indicator
light in the instrument cluster
Q page 158 .
-A sensor in each front seat registers the dis ­
tance between the respective seat and the
steering wheel or instrument pane l. The infor ­
mation reg istered is sent continuously to the
electronic control un it to regulate deployment
of the front Advanced Airbags .
- The
PASS ENGER AIR BA G OFF light comes on
and stays on in the center of the instrument
panel
Q page 158, fig . 156 and tells you when
the front Advanced A irbag on the passenger
s ide has been turned off .
- A sensor in the safety belt latch for the driver
and for the front seat passenge r that senses
whethe r th at safety belt is latched or not and
t ransm its this info rmat ion to the electronic
contro l unit.

_&. WARNING
Damage to the front passenger seat can pre­
vent the front airbag from work ing properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced A irbag System from function ing
properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
wo rkshop personne l.
- Never remove the front passenger or driver seat from the vehicle .
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble or remove parts from the
seat or disconnect wires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detect ion mat in the front passenger
seat will not function p roperly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. Such ob­
jects can influence the capacitance regis­
tered by the capaci tive passenger detection
system, so that incorrect in format ion is pro­
vided to the airbag control unit.
- Never store i tems under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working p roper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child res tra int system on
this seat.
- Never use cushions, p illows, blankets, or
sim ila r items on the front passenge r seat.

" N .... 0 00 \,;J ' A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat will be seri ­
ously injured and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position and have the airbag system inspected by
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates .
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the front passenger seat. Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags inflate .
- Never recline the front passenger 's seat to
transport objects. Items can also move into
the area of the side airbag or the front air-
-
Airbag system
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat.
- Always make sure that there is nothing on the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is not , or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat.
A WARNING ...__ -
The fine dust created when airbags deploy can
cause breathing problems for people with a history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.

ligh t.
The Advanced Airbag System as well as the side
airbags and side curtain airbags with eject ion
mitigation features (including the e lectroni c con­
trol unit, sensors and system wiring) are all
monitored continuously to make sure that they
are funct ion ing prope rly whenever the ignition is
on . Every time you turn on the ignition, the air­
bag system indicator light
II (USA models) 1fll
(Canada models) will come on for a few seconds
(function check).
The system must be inspected when the
indicator light
II (USA models) tfll
(Canada models):
-does not come on w hen the ignition is switched
on,
-does not go out a few seconds after you have
switched on the ign ition, or
-comes on wh ile driving .
If an airbag system ma lf u nction is detected, the
ind icator light wi ll 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 igni tion is on .
A WARNING
An airbag system that is not funct ioning prop­
erly cannot provide supplemental protection
in a frontal crash .
-If the airbag indicato r light ¢page 16
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer . It is possible that
158
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.

The PASSENGER AIR BAG OFF light is located in
the center of the instrument panel ¢
fig. 156.
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 contro l unit . If the bulb for the
PASSENGER AIR BAG OFF light burns out, the
airbag indicator light
II (USA models) a (Can­
ada models) will come on to signal a malfunction
i n the Advanced A irbag System. Although the
burned-out bulb will not change the way the
front passenger's frontal airbag works, it wi ll no
l onger be poss ible to use the
PASSENGER AIR

lig ht to make sure that the a irbag on/
off status is correct for the occupant on the front
passenger seat . Have the airbag system inspect­
ed immediately by your author ized Audi dealer .
The PASSENGER AIR BAG OFF light will blink
for about 5 seconds when:
-the ignition is switched on and
- the capacit ive 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

PLACEMENT RECORD .
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al

rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed . Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
162
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
teristics as the components origina lly instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Aud i.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.

The driver knee airbag is in the instrument panel
underneath the steering wheel ¢
fig. 157, the
airbag for the passenger is at about the same height in the instrument panel underneath the
glove compartment.
The knee airbag offers add itional protect ion to

rest facing the doors . They are identified by the
word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
he lp reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitt ing next to it is not seated prop­
erly. The s ide airbag for the front passenger seat
can be used with properly installed child re­
stra ints. Please be sure to read the important in­
formation and wa rnings whenever us ing a child

Th e s ide airbag system ba sically con sis ts of :
-the electron ic control module and externa l side
i mpact sensors
- the two airbags located in the sides of the front
backrests and the two airbags* located in the
rear back rest
- the a irbag warning light in the instrument cl us-
ter .
The airbag system is monitored electronically to make certain that it is functioning properly at all
times . Each time you switch on the ign ition, the
a irbag system indicator light will come on for a
few seconds (self diagnostics).
The s ide airbag system supp lements the safety
belts and can help to reduce the risk of in jury to

side coll is io n. T he a irbag dep loys only i n side im­
pacts and o nly when the veh icle accelerat ion reg ­
istered by the contro l un it is high enough. If this
rate is below the reference value programmed in ­
to the control unit, the side airbags wi ll not be
tr iggered, even though the car may be bad ly
damaged as a result of the collision. It is not pos­
sib le to define an airbag tr igger ing range that
will cover every possib le ang le of impact, s ince
the c ircumsta nces will vary cons iderably between
one co llision and another. Important facto rs in­

structions on the side airbag system .
Aside from the ir norm al safety funct ion, safety
belts work to help keep the dr iver o r front pas ­
senger in position in the event o f a side co llision
so that the side airbags can provide protection .
T he air bag system is
not a substitute fo r you r
sa fety be lt. Ra ther, i t is pa rt of the overall occ u­
pant restraint system in your vehi cle. Always re ­
member that the side airbag system can only
help to protect you if you are wear ing you r safety
belt and wear ing it properly. This is another rea­
son why you should a lways wear your safety
belts, not just because the law requires you to do
soc:!;> page 138, General information .
It is important to remember that while the sup­
plementa l side airbag system is designed to re­
duce the likelihood of ser ious injuries, other inju ­
ries, for example, swelling, bru is ing, friction
bur ns and m ino r abras ions can also be assoc iated
with deployed s ide airbags. Remember too, s ide
airbags will deploy only once and only in certa in
ki nds of accidents
-your safety belts are a lways
the re to offer protection .
Vehicle damage, repair costs o r even the lack of
vehicle damage a re not necessar ily an ind ic a tion
of over-sens it ive or fa iled air bag ac tiva tion . In
some collisions, both front and side airbags may
inflate. Remember too, that airbags wi ll dep loy
on ly once and only in certain kinds of collisions
-
your safety belts are always there to offer protec­
t ion in those accidents in which airbags are not
supposed to deploy or when they have al ready
deployed .
The side airbag system will not deploy :
- when the ignition is switched off
- in side co llisions whe n the accele ration meas -
ured by the sensor is too low
- in front -end col lisions
- in rea r-end co llisions
- in rollovers.
In some types of accidents the front a irbags, side
curtain airbags and s ide a irbags may be tr iggered
