Airbag system
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
Q page 268,
Airbag system Qpage 277, Ch ild safety
c::> page 302 .
The side airbag system basically consists of:
-the e lectronic control modu le and externa l side
impact sensors
- the two side airbags located in the sides of the
front backrests
- two rear side airbags*
- the airbag warning light in the inst rument clus -
ter.
The airbag system is monitored electronically to make certa in that it is functioning properly at all
times. Each time you turn on the ign it ion, the air­
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger 's upper
torso on the side of the vehicle that is struck in a
side co llision. The a irbag dep loys only in side im­
pacts and on ly when the vehicle acceleration reg­
istered by the control unit is high enough . If this
rate is below the reference value programmed in­
to the control un it, 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 pos­
sib le to define an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collision and another . Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
Q page 297, Important safety in­
structions on the side airbag system.
Aside from their normal safety function, safety be lts work to help keep the driver or front pas­
senger in pos it ion in the event of a s ide collision
so that the side a irbags can provide protection.
The airbag system is
not a subst itute for your
safety belt. Rather, it is part of the overall occu-
296
pant res traint 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 wearing 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 268, General information .
It is important 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, bru is ing, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
a irbags w ill dep loy only once and only in certa in
kinds of accidents
-your safety belts are always
there to
offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an ind icat ion
of over-sens itive or fa iled airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags wi ll deploy
on ly once and only in certain kinds of collisions
-
your safety be lts are always there to offer protec­
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
- when the ignition is turned off
- in side co llisions when the acceleration meas -
ured by the sensor is too low
- in front-end collisions
- in rea r-end collisions
- in rollovers.
In some types of accidents the front airbags, side
curta in airbags and side a irbags may be triggered
together .
&_ WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position
Q page 29 7.
- If the airbag indicato r light Q page 32
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that

-Never use additiona l seat cushions that
cover the areas where the s ide airbags
deploy.
- Damage to the original seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer .
- Objects between you and the airbag can in­
crease the risk of injury in an accident by in­
terfering w ith the way the airbag unfolds or
by being pushed into you as the a irbag in­
flates.
- Never p lace or attach accessories or other
objects (such as cupholders, telephone
brackets, or even large, bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests.
- Such objects and accessories can become
dangerous projectiles and cause injury
when the supplemental s ide airbag de­
p loys.
- Never carry any objects or pets in the de­
ployment space between them and the
airbags or allow ch ildren or other passen­
ge rs to travel in this posit ion.
- Always use the built-in coat hooks* only for
lightweight cloth ing . Neve r leave any heavy
o r sharp-edged objects in the pockets that
may interfere w ith side airbag dep loyment
and can cause personal injury in an accident .
- Always preven t the side airbags from be ing
damaged by heavy objects knock ing against
or hitting the sides of the seatbacks .
- T he airbag system can only be trigge red
once . If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership.
- Damage (cracks, deep scratches etc.) to the
original seat covers or to the seam in the
area of the side airbag modu le must always
be repa ired immed iate ly by an authorized
Audi dealer.

The side curtain airbags are located on both sides
of the interior above the front and rear side win­
dows

interior in certain side impacts and vehicle
ro llovers .
The s ide curtain a irbag system supplements the
safety be lts and can he lp to reduce the risk of
in­
jury for occupants' heads and upper torso in a
side col lision . The side curtai n airbag inflates in
side impacts and only when the vehicle accelera­
tion reg istered by the control un it is high
enough. If th is rate is below the reference value
programmed into the control unit, the side cur ­
tain airbag will not be triggered, even though the
car may be badly damaged as a result of the colli­
sion.
It is not possib le to define an airbag tr igger­
i ng range tha t will cover every possib le ang le of
impact, since the circ ums tances will vary consid­
e rably between one co llision and another . Impor ­
tant factors include, for examp le, the nat ure
(hard or soft) of the impact ing ob ject, the angle
of impact, vehicle speed, etc.
Q page 300, How
side curtain airbags work.
Aside from their normal safety function, safety be lts work to help keep the driver or front pas­
senger in posit ion in the event of a collision so
that the side curtain airbags can provide protec­
tion .
The airbag system is not a subst itute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your veh icle. Always
re­
member that the airbag system can only help to
protect you if you are wea ring your safety belt
a nd wear ing it properly . T his is anothe r reason
why you should always wear your safety be lts,
n ot j ust because the law requires you to do so
Q page 268, General information.
It is important to remember that wh ile the s ide
curta in a irbag system is des igned to he lp reduce
the l ikel ihood of ser ious injuries, o ther i njuries,
for example, swel ling, b ruising, friction burns
and minor abrasions can also be associated with
these airbags upon deployment. Remember too,
these airbags will deploy only once and only in
certa in kinds of acc idents
-your safety belts are
always there to offer protection .
Airbag sys tem
The side curtain airbag system basically
cons ists of :
-The e lectronic control mod ule and externa l side
impact sensors
- The side curtain airbags above the windows of
the outer seating positions with eject ion mit i­
gation features
- The airbag indicator light in the instrument
panel
T he airbag system is mon itored e lectron ica lly 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 co llisions whe n the ac celeration meas-
ured by the sensor is too low
- in rear -end co llisions.
_&. WARNING
- Safe ty belts and the airbag system will only
provide protect ion when occupants are in
the proper seating position
Q page 71,
Front seats.
- If the ai rbag ind icator light Q page 32
comes when the vehicle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possib le that
the airbag will inflate when it is not sup­
posed to, or w ill not inflate when it should.

Wheels
check you r tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
also reduces fuel efficiency and t ire tread life,
a nd may affect the veh icle's handling and stop ­
p ing ability .
Please note that the TPMS is not a substit ute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat io n of the TPMS low tire p res­
sure tellta le.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion i nd icator to indicate when the sys­
t e m is not operat ing properly. The TPMS ma l­
f u nction indicator is comb ined w ith the low tire
p ress ure tellt ale. Whe n the system dete cts a
malfunct ion, the te lltale will flash for approxi­
mate ly one min ute and then remain continuo usly
i l luminated. This sequence will continue upon
subseq uent veh icle start- ups as long as the ma l­
function ex ists .
When the malf unctio n indicator is ill uminated,
the system may not be able to detect or signa l
low tire pressure as intended . TPMS ma lf u nctions
may occur for a variety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning prope rly . Always c heck the

p roperly.
If the tire pressure monitoring indicator
appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure mon itor­
ing system compares the tire tread circ umfer­
ence and vibration cha racteristics of the individu­
a l tires. If the pressure changes in one or more
tires, this is ind icated i n the instrument cluste r

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 required cleaning and care products can be
obtained from an authorized Audi dealer or au­
thorized Service Facility. Read and follow the in­
structions for use on the packaging .
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health .
- Always store cleaning and care products out
of reach of children to reduce the risk of poi­
soning .
@ For the sake of the environment
- Preferably purchase environmentally-friend­
ly cleaning products.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve­ hicle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect .
Before washing, rinse off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
Also, wash the underside of your vehicle once road salt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash ­
er, always follow the operating instructions pro­
vided with the pressure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at seals on
362
side windows, doors, the hood, the luggage com­
partment lid or the panorama glass roof* or at
tires, rubber hoses, insulating material, the pow­
er top*, sensors* or camera lenses". Keep a dis­
tance of at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozzles or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °() .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows, the panorama glass
roof* and the power top* are closed and the
windshield wipers are off. Follow instructions
from the car wash operator, especially if there
are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the vehicle starting from the top and work­
ing down using a soft sponge or cleaning brush.
Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutra l shampoo and a soft micro­
fiber cloth.
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a chamois.
