-In a side collision, side airbags will not func­
tion properly if sensors cannot correctly
measure increasing a ir pressure inside the
doors when air escapes through larger, un­
closed openings in the door panel.
- Never drive w ith inter ior door trim pane ls
removed.
- Never drive when parts have been re­
moved from the inside door panel and the
openings they leave have not been proper­ ly closed.
- Never drive when loudspeakers in the doors have been removed un less the
speaker holes have been properly closed.
- Always make certain that openings are
covered or fi lled if additional speakers or
other eq uipment is installed in the inside
door panels.
- Always have work on the doors done by an
author ized Audi dealer or qualif ied work­
shop.
Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc­
cupants.
F ig . 127 S ide curtain sys te m , dr iver's side: s ide c urta in air­
bag locat ion
The s ide curtain airbags are located on both sides
of the interior above the front and rear s ide win­
dows
Q fig. 127 . They are iden tified by the wo rd
"AIRBAG" on the w indshield frame and the ce n­
ter roof pillar.
The s ide curta in airbags contain features that
p rovide ejec tion mi tiga tion to help p reve nt veh i-
Airb ag sys tem
cle occupants or par ts of their bodies from being
completely or partially ejected from the vehicle
i nterior in certain side impacts and veh icle roll­
overs .
T he side curtain airbag system supplements the
safety belts and can help to reduce the risk of in­
j ury for occupants' heads and upper torso on the
s ide of the vehicle that is struck in a side colli­
sion. The s ide curtain airbag inflates in side im­
pacts and only when the vehicle acce leration reg­
istered by t he control unit is high enough . If this
rate is be low the reference va lue programmed in­
to the control unit, the side cu rtain airbag will
not be t riggered, even though the ca r may be
badly damaged as a resu lt of the co llision . It is
not possible to define an airbag triggering range
that wi ll cover every possible angle of impact,
s ince the circumstances will vary considerably be­
tween one collision and another. Important fac­
tors include, for example, the nature (hard or
soft) of the impact ing object, the angle of im ­
pact, vehicle speed, etc .
Q page 130, How side
curtain airbags work.
Aside from their normal safety funct ion, safety
belts work to help keep the drive r or front pas ­
senger in position in the event of a coll is ion so
that the s ide curtain a irbags can prov ide p rotec­
t ion.
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overall occ u­
pant restraint system in your vehicle. Always re­
member tha t the ai rbag system can on ly help to
pro tec t you if you are wear ing you r sa fety be lt
and wearing it properly . This is another reason
why you shou ld always wear yo ur safety belts,
not just because the law req uires you to do so
Q page 104, General information.
It is important to remember that while the side
cu rtain airbag system is designed to help reduce
the likelihood of serio us injuries, other injuries,
for example, swelling, bru ising, and minor abra­
s ions can also be assoc iated with these airbags .
Remember too, these airbags will deploy only
once and on ly in ce rtain k inds of accidents -your
safety belts are always there to offer protec tion. ..,.

Airbag system
The side curtain airbag system basically
consists of:
- The electronic control module and external side
impact sensors
- The side curta in airbags above the front and
rear side windows with ejection mitigation fea­
tures
- The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make certain it is functioning 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 curtain airbag is not activated:
-if the ignition is turned off,
-in side collisions when the acceleration meas-
ured by the sensor is too low,
- in rear-end collisions.
,&. WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position
¢ page 50,
Front seats.
-If the airbag indicator light ¢page 16
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer . It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.

How side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who are properly re­
strained.
Fig. 128 Illus tratio n of principle: I nflated side curtain a ir­
bag s on t he left s ide
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the vehi­
cle that is struck in a side collision
~ fig. 128.
When the system is triggered, the side curtain
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In order
to help provide this additional protection, the
side curtain airbag must inflate within the blink
of an eye at very high speed and with great force.
The side curtain airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the supple­
mental side curtain airbag inflates. This applies
especially to children~
page 132.
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the risk of injury to the
head and the upper part of the body.
A fine dust may develop when the airbag deploys .
This is quite normal and does not mean there is a
fire in the vehicle .

exceptional circumstances and the
PASS ENGER AIR BAG OFF light does not
come on and stay on, immed iately install
the rear-fac ing ch ild safety seat in a rear
seating pos it ion and have the airbag system
inspected immediately by your Audi dealer .
A WARNING
If, in exceptio nal circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-fac ing seat
has been designed and ce rtified by its man­
ufact urer fo r use on a front seat with a pas­
senger front and side airbag .
- Always follow the manufact urer's instruc­
tions prov ided with the ch ild safety seat or
carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le before installing the child
restraint. The backrest must be adjusted to
an upr ight position.
- Always make sure that the
PA SSENGER AIR
BAG OFF
light comes on and stays on all the
t ime whenever the ignition is switched on.
{D) Tips
Always replace chi ld restraints that were in­
stalled in a vehicle dur ing a crash . Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your veh icle is equipped with a front "Advanced
Airbag System " in compliance w ith United States
F edera l Moto r Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Ve hicle Safe ty
Stand ard (CMVSS) 208 as appli cable at the t ime
your vehicle was manufactured .
The Advanced Airbag system in your ve hicle has
been ce rtified to meet the "low-risk " requ ire­
ments for 3 -and 6-year old children on the pas­
senger side and small adults on the driver side .
The low risk deployment criteria are intended to
Ch ild safety
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instr ument
panel when the airbag inflates. In addition, the
system has been cert ified to comply with the
"suppression" requirements of the Safety Stand ­
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in ch ild rest raints that are lis ted in
the S tanda rd .
Even thoug h your veh icle is equipped with an Ad­
vanced Airbag system, all ch ildren, especially
those 12 yea rs and younger, sho uld a lways ride
i n the back seat properly restra ined for their age
and size . The airbag on the passenger side makes
the front seat a potentia lly dangerous p lace for a
child to ride. The front seat is not the safest place
for a ch ild in a forward-fac ing ch ild safety seat. It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat .
Advanced Airbags and the weight -sensing
mat in the front seat
T he Advanced A irbag System in you r vehicle de­
tects the presence of a n in fan t or child in a ch ild
restra int 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 chi ld safety seat and a child
blanket on the front passenger seat. The weight
on the front passenger seat is related to the de­
s ign of the child restra int and its "footprint" , the
s ize and shape of the bottom of the c hild re ­
straint as it s its on the seat. The weight of a chi ld
r estra int and its "footprint " va ry for different
k inds of child restra ints and for the different
models of the same kind of ch ild rest raint of ­
fered by child restraint manufacturers.
T he weight ranges for the individ ual types,
makes and mode ls of chi ld restrain ts that the
N HT SA has spec ified in the Safety Standard to­
gether with the weight ranges o f typical infants
and typical 1 year-old chi ld have been stored in .,.
133

Child safet y
the control unit of the Advanced Ai rbag System.
When a chi ld restraint is being used on the front
passenger seat with a typical 1 year-old child, the
Advanced Airbag System compares the we ight
measured by the weight sensing mat with the in­
formation stored in the electronic control unit.
The electronic cont rol 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 adult who is properly
using the safety belt as compared to the tension
on the belt when it is used to attach a ch ild re­
stra int to the seat. The senso r below the la tch fo r
the safety belt for the fro nt sea t passe nger
meas ures the tens io n on the belt. The inp ut from
this sensor is then used with the weight to "de­
cide", whether there is a child restraint with a
typical 1 year-old child on the front passenger
seat and whethe r or not the a irbag must be
turned off.
Child restraints and Advanced Airbags
Regardless of the child restra int tha t you use,
make sure that it has been cert ified to meet Safe­
ty Standa rds and has been certified by its manu­
facturer for u se wi th an a irb ag. Always be sure
t ha t th e chi ld res tra in t i s properly insta lled at
one o f th e rear seating posit ions . If i n excep tion ­
a l ci rcumstances yo u must use it on the front
passenger seat, carefully read all of the informa­
tion on child safety and Advanced Airbags and heed a ll of the app licab le WARNINGS. Make cer­
tain that the child restra int is correctly recog­
n ized by the we ight-sens ing mat inside the front
passenger seat, that t he fron t passenger a irbag
is tu rned off and tha t the airbag status is a lways
cor rect ly signa led by the
PASSENGER AIR BAG
OFF ligh t.
M any types and models of c hild rest rai nts have
been available ove r th e yea rs, new models are in­
t roduced regularly incorporat ing new and im ­
p roved designs and o lder mode ls are taken o ut o f
p roduction . Chi ld restraints a re not standardized .
Ch ild rest raints of the same type typica lly have
d ifferent weights and s izes and d ifferent 'foot­
prints, ' the size and shape of the bottom of the
chi ld restraint that s its on the seat, when they
134 are ins
talled on a vehicle seat . These d ifferences
make it virtua lly impossib le to certify compliance
with the requirements for advanced a irbags w ith
each and every child restra int that has eve r been
sold in the past or will be so ld over the course of
the usefu l life of your vehicle.
Fo r thi s reason, the United States Nationa l H igh­
way Traffic Safety Administration has published a li st of specific type, makes and mode ls of ch ild

of reach of children to reduce the r isk of po i­
so ning .
@ For the sake of the environment
- Preferab ly use environmentally-friendly
products when buying cleaning agents.
- Do not dispose of leftove r clean ing and care
products wit h household t rash.
Car washes
The longer that deposits remain on the veh icle,
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
p lenty of water.
Stubborn deposits s uch as bird droppings or tree
sap are best removed with plenty of water and a mic rofibe r cloth.
A lso, wash the underside of yo ur vehicle once
road sa lt stops being used for the season .
Pressure washers
When washing your veh icles with a pressure
washer, always follow t he ope ra ti ng inst ructions
p rovided w ith the pressure washer. This is espe­
cially important in regard to the pressure and
spraying distance . Do not a im the spray directly
at seals on side windows, doors, the hood, the
168
rear lid or the sunroo f* or at tires rubber hoses I I
insulating material, sensors* or camera lenses* .
Keep a distance of at least 16 inches (40 cm) .
Do no t remove snow and ice with a pressure
washe r.
Neve r use rota ry no zzles or high pressure noz­
z les.
The water temperatu re must not be above 140 °F
(60 °().
Automatic car washes
Spray
off the vehicle before washing.
Make su re that the windows and roof * are closed
and t he windshie ld wipers are
off . Follow instruc ­
tions from the car wash operato r, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing
by hand
Clean the vehicl e starting from the top and work­
in g down using a soft sponge or cleaning br ush .
Use solvent-free cleaning products.
Washing vehicles with matte finish paint
by
hand
To avo id damaging the paint w hen washing, fi rst
remove dust and large pa rt icl es from your vehi­
cle. Insects, grease spots and fingerprints are
best removed with a special cleane r for matte
finish paint .
Apply the p rodu ct using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse the vehicle thorough ly w ith wate r. Then
clean using a neutra l shampoo and a soft m icr o­
fiber cloth .

- 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 brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . The brakes
must be dried first w ith a few careful brake
applica tions .
- If you wash the vehicle in an automatic car
wash, yo u m ust fold the exterior m irrors i n
to reduce the risk of damage to the mirrors.

Check ing and F illing
The location of the coolant expansion tank can be
seen in the engine compartment illustration
c::> page 179.
To obtain an accura te reading, the eng ine must
be switched off .
The expans io n tank in your vehicle is equipped
with a n elec tric coolant level sensor.
When the coolant level is too low, the war ning
lig ht in the Auto-Check System
c::> page 14 will
blin k until you add coo la nt and the level has bee n
restored to normal. Even t hou gh the re is an e lec­
tr ic coolant level sensor, we still re commend you
check the coo lant level from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system. I n the event of coolant loss, the cooling
system should be inspected immediately by your
author ized Audi dealer. It is not enough me rely
to add coolant.
I n a
se aled system, losses can occur only if the
boi ling point of the coo lant is ex ceeded as a re ­
sul t of over heat ing.
A WARNING
T he cooling system is unde r pressure and can
get very hot . Red uce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and a llow it to cool
down .
- Protect your face, hands and arms from es ­
caping fluid and steam by cove ring the ca p
with a la rge, thick rag.
- Turn the cap s lowly and very ca refu lly in a
counter-clockwise direction w hile ap ply ing

cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exha ust system or
hot eng ine parts. Under certain conditions,
the ethy lene g lycol in e ngine coolant can
catch fire.
(D Note
Do not add any type of radiato r leak sealant
to your veh icle's engine coolant. Adding radia-

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
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
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuous ly
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 ab le to detect or signal
low tire pressure as intended . TPM S 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.
