front three-point safety belts to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the important
information about safety and heed the WARN­
INGS in this chapter.
Deployment of the Advanced A irbag System and
the activation of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit . Crash severity depends on speed and decel ­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash .
On the passenger side, regardless of safety belt
use, the front passenger frontal airbag will be
turned off if the electrical capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in the electronic control unit. The
front passenger frontal airbag will also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys­
tem under Federal Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF '1; light
comes on and stays on to tell you when the front
Advanced Airbag System on the passenger side
has been turned off

A WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­
ting sideways or out of position in any way,
your risk of injury is much higher.
- You will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates
-
even with an Advanced Airbag Qpoge 194.

More important things to know about front
airbags
Fig. 163 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­
plemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protection for the chest and face of the
driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so tha t the oc-
cupant is properly seated as far as possible
from the airbag.
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have
placed on the seat could become dangerous pro ­
jectiles, and be pushed into you if the airbag in­
flates.
When an airbag deploys , fine dust is released.
This is normal and is not caused by a fire in the
vehicle . This dust is made up mostly of a powder
used to lubricate the airbags as they deploy.
It
could irritate skin.
It is important to remember that while the sup ­
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra­
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supp lement the three
point safety belts only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags.

Airbag syste m
Front airbag s will not d eploy:
- i f the ig nition is switched off whe n a cr ash oc-
cu rs,
- i n s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash decelerat ion measured by the
airbag system is less than the minimum thresh ­
old needed for airbag deployment as registered
by the electronic contro l unit .
The front p assenger airb ag will also not
deploy:
- when the front passenger seat is not occup ied,
- whe n the electrical capac itance measured by
the capacitive passenger detect ion system for
the front passenger seat indicates that the pas­
senger side frontal airbag must be switched off
by the electronic contro l unit (the
PASSENGER

they work comes on and stays on) .
.&_ WARNING
Sitting in the wrong position can increase the
risk of serious injury in crashes.
- To reduce the risk of injury when the airbags inflate, the driver and passengers must al­
ways sit in an upright position, must not
lean against or p lace any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of position
or too close to the a irbag can be seriously
injured by an airbag as it unfolds with great
force in the b link of an
eye <=;> page 195.
.&_ WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inflates
-even with an Advanced Airbag
System.
- T he inflating a irbag w ill hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.

- Never install a rearward facing chi ld safety
seat on the front passenger seat unless the
PAS SEN GER AIR B AG OFF ~; light comes
on and stays on . If the
PA SSENGER AIR
BAG
OFF ~; light does not come on and stay
on, the inflat ing airbag will hit the chi ld
safety seat or infant carrie r wi th great force
and will smash the child safety seat and
child against the bac krest, door or roof .
Have the airbag system inspected immedi­
ately by your authorized Audi dealer .
.&_ WARNING
Objects between you and the airbag will in­
crease the r isk 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 veh icle 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 maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.
- Never place or attach accesso ries o r othe r
objects (such as cup holders, telephone brackets, large, heavy or bulky ob jects) on
the doo rs, ove r or near the area ma rked
"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 a irbags inflate.
- Never recl ine the front passenger's seat to
transport objects. Items can also move into
the area of the side a irbag or the front air­
bag during brak ing or in a sudden maneu­
ver. Objects near the airbags can become projecti les and cause injury, part icularly
when the seat is reclined.
- Never p lace or t ransport objects on the
-
front passenger seat. Objects on the front
passenger seat could ca use the capaci tive
sensor in the seat to signal to airbag system
that the seat is occ upied by a person when it

Airbag syste m
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
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic cont rol u nit. Some suspension c hanges
can, for example, increase the fo rce leve ls meas­
u red by the sensors and make t he a irbag system
deploy in crashes in which it wou ld not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the a irbag from deploy­
ing when it should.
A WARNING
-
Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag perfo rmance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components o riginally instal­
led on your vehicle .
-Never use tire-rim combin ations that have
not been approved by Audi .

Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passenger .
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated.
- If children are incorrectly seated, their risk
of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 167 Side airbag locat ion in t he drive r's se at
The side airbags are located in the sides of the
front seat backrests
c:> fig. 167 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
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
c:> page 187,
Airbag system c:>page 194, Child safety
c:> page 216 .
The side airbag system basically consists of:
-the electronic control module and externa l side
impact sensors
212
-the two side airbags located in the sides of the
front backrests
-the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ically to
make certain that it is functioni ng 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 airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­
lision. The airbag deploys in side impacts and on­
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
unit, the side airbags will not be tr iggered, even
though the car may be badly damaged as a result
of the collision.
It is not possible to define an air­
bag triggering range that w ill cover every possi­
ble angle of impact, since the circumstances will
vary considerably between one collision and an­
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
c:> page 214, Important safety instructions on
the side airbag system.
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 side collision
so that the side airbags can provide protection.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wear ing it properly. This is another rea­
son why you sho uld always wear your safety
belts, not just because the law requires you to do
so
c:> page 187, General notes.
It is impo rtant to remember that while the sup­
plemental side airbag system is designed to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bruising , friction
burns and minor abrasions can also be associated

with deployed side airbags. Remember too, side
airbags wi ll deploy on ly once and on ly in certain
kinds of acc idents -your safety be lts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
ve hicle damage are not necessarily an indication
of over-sensitive or failed airbag act ivation. In
some collisions, both front and side a irbags may
inflate. Remember too, that airbags will deploy
only once and only in ce rtain kinds of coll is ions
-
your safety belts are always there to offer protec­
tion in those acc idents in which airbags are not
supposed to deploy or when they have already
deployed.
The side airbag system will not deploy:
-when the ign ition is switched off
-in side collisions when the acceleration meas-
ured by the sensor is too low
-in front-end collisions
-in rear-end collisions
-in rollovers.
I n some types of accidents the front airbags and
side airbags may be triggered together.
_& WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position¢
page 214.
-If the airbag indicator light q page 14
comes when the vehicle is being used, have
the system inspected immed iate ly by your
authorized Audi dealer. It is possible that
the a irbag will inflate when it is not sup­
posed to, or will not inflate when it should.
Airbag system
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.
Fig. 168 Inflated side airbag on left side of vehicle
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked "AIRBAG". It ex­
pands between the side trim panel and the pas­
senger . In order to help provide this addit ional
protect ion, the side airbag must inflate w ith in a
fraction of a second at very high speed and with
great force. The supplemental sid e a irbag could
injure you if you r seating position is not proper or
u pr ight or if items are located in the area where
the supp lemental side airbag expands . This ap­
plies especially to children
¢ page 216, Child
safety.
Supplementa l side airbags inflate be ­
tween the occupant and the door panel on the
s ide of the vehicle that is struck in certain side
collision ¢
fig. 168.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper part
of the body .
A fine dust may develop when the airbag deploys.
This is normal and does not mean there is a fire
in the veh icle.

Airbag syste m
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
p roperly wear safety belts and ride in a proper
seating position.
There is a lot that you and your passengers must
know and act accord ingly to help t he safety be lts
and a irbags do the ir job to provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury . Improperly wearing safety belts
and improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used .
- In order to reduce the risk of injury when
the supplemental s ide airbag inflates:
- Always sit in an up right posit ion and never
lean ag ainst the area where the s upple­
mental side airbag is located.
-
- Never let a chi ld or anyone else rest the ir
head agains t the side t rim p anel in the
area whe re the supp lemental s ide a irbag
inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the fron t seat
put their hand or any other parts o f the ir
body out of the window .
- Always make sure tha t the side airbag can
inflate without inter ference.
- Never install seat covers or rep lacement
upho lstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags de­
ploy .
- Damage to the origina l seat covers or to
the seam in the area of the side airbag
mod ule m ust always be repaired immed i­
ately by an authorized Audi dealer.
- Objects between you and the airbag can in­
cr ease t he risk of inju ry in an accident by in­
te rfe ring w ith the way the airb ag unfo lds or
214 by being pushed
into you as the airbag in­
flates .
- Never place or attach accessor ies or other
ob jects (s uch as cup ho lde rs, telephone
bracke ts, or even l arge, b ulk y objec ts) on
the doors, over or near the area mar ke d
"A IRBAG" on the seat backrests .
- Such objec ts and accessories can become
dange ro us projecti les and cause injury
when the supplemental side airbag de­ ploys.
- Never carry any objects or pets in the de ­
ployment space between them and the
airbags or allow children or other passen­
gers to trave l in this position .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The a irbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
Aud i dealership.
- Damage (cracks, deep scratches etc.) to the
or iginal seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Aud i dea le r.
- If ch ildren are seated imprope rly, thei r risk
of injury increases in the case of an accident
~ page 216, Child safety .
-Never attempt to mod ify any components of
the airbag system in any way.
- In a side collision, side airbags will not func­
tion properly if sensors cannot correctly measure increasing air press ure inside the
doors when a ir e scapes th rough large r, un­
closed openings in the door p anel.
- Never dr ive with interior door t rim panels
removed.
- Never dr ive when parts have been re­
moved from the inside door panel and the
openings they leave have not been proper­
ly closed .
- Never dr ive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed .

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 264. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 264 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 264:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see

Care and cleaning
Care and cleaning
General information
Regular, proper care helps to maintain your vehi­
cle's value. It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The necessary care products can be obtained
from an authorized Audi dea ler or authorized
Audi Service Facility. Read and follow the instruc ­
tions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
- Always store clean ing and care products out
of reach of children to reduce the r isk of poi­
sonin g.
@ For the sake of the environment
- Preferab ly purchase environmenta lly-friend­
l y cleaning products.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer that deposits remain on the vehicle,
the more the surface may be damaged. High
temperatures such as those caused by sunlight increase the damaging effect .
Before washing, rinse
off heavy deposits with
