conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
ployment are met.
- Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant restraint system in your vehicle .
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right, wearing your safety belt and wearing it
properly. This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle
has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in-
Airbag system 187
jury through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard
~ page 205, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re­
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com­
pliance with the US Safety Standard
~page 205,
-weight less than a thresho ld level stored in
the control unit is detected on the front pas­
senger seat .
When a person is detected on the front pas ­
senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­ quires the front airbag to be turned off . If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory. ..,. •

-Always make sure the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat

- Never put the forward-facing child re­
straint up aga inst or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more . 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 un it mon itors the Advanced Air ­
bag Sys tem and turn s the a irbag i ndica tor
light on when a ma lfunction in t he system
components is detected . The function of the
airbag indicator light is described in greater
deta il below. Because the front passenger
seat contains important parts of the Ad­
va nced A irbag System, you must take care to
prevent it from being damaged . Damage to
the seat may p revent the Advanced A irbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle accelera tion/decele ra ti on
to provide info rm ation to the Advanced Air ­
bag System abo ut the severity of the crash.
A irbag system 189
-An elect ron ic cont ro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to f ire
the front a irbags based on the informat ion
received from the crash sensors. The control
unit also "decides" whether the safety belt
prete nsione rs shou ld be act iva ted.
- An Advanced A irbag w it h gas generator for
the driver inside the steering wheel hub .
- An Advanced A irbag w ith gas generator in­
side the instrument pa nel for the front pas­
senge r.
- A weight-sensing mat under the upholstery
padding of the front passenge r seat cushion
that measures the to tal weight o n the seat.
The informat ion reg iste red is sent continu­
ously to the elect roni c con trol u nit to regu­
la te deployment of the front Adv anced Air­
bag on the passenger side .

seat as sensed by th e Advanced Airbag Sys­
tem indicates that the front airbag on the
passenger side has to be turned off by the
electronic control unit (the
PASSENGER AIR
BAG OFF
light comes on and stays on)
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located.
- Occupants who are unbelted, out of posi­
tion or too close to the airbag can be se­
riously injured by an airbag as it unfolds
with great force in the blink of an eye
¢page 184.
A WARNING -
A child in a rearward-facing child safety
seat installed on the front passenger seat
will be seriously injured and can be killed if
the front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by being 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 air­
bags during braking or other sudden ma­
neuvers and become dangerous projec­
tiles that can cause serious personal in­
jury if the airbags inflate.
- Never place or attach accessories or oth­
er objects (such as cupholders, tele­
phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yourself . These
objects could cause injury in a crash, es­
pecially 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 airbag during braking or in a
sudden maneuver. Objects near the air­
bags can become projectiles and cause
injury, particularly when the seat is re­
clined.
- Never tilt the front passenger seat back­
rest forward when the vehicle is moving.
An inflating airbag will force the back­
rest backward and can injure rear seat oc­
cupants.
A WARNING
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath­ ing conditions.

A WARNING
If the front airbag inflates , a ch ild without
a child restraint, or in a rearward-facing
child safety seat, or in a forward-facing
child restraint that has not been properly
installed will be serious ly inju red and can
be killed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that al l children, especially 12
years and younge r, a lways rid e on the

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
& WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cu­ pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water . Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
-All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary. -
For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary .
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­ placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped , all applicable safety pre­
cautions must be followed.

The airbag system is not a substitute for yo ur
safety be lt. Rathe r, it is part of the overall oc­
cupant restraint system in your veh icle. Al­
way s remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it prope rly . Th is
i s another reason w hy you shou ld always wear
your safety belts, not just beca use the law re­
qu ires you to do so~
page 173 , General
notes.
It is important to remember that while the
side curta in a irbag system is designed to he lp
r educe the like lihood of serious injur ies, other
i nj uries, fo r example , swelling , bruising, and
minor abrasions can also be associated w ith
these airbags upon deployment . Remember
too, these airbags wi ll dep loy on ly once and
only in certain kinds of accidents -your safety
be lts are always there to offer protection.
The side curta in airbag system basically
con sist s o f:
- The electronic contro l mod ule and externa l
s ide impa ct sensors
- The side curtain airbags above the front and
rear side w indows
- The airbag indicator l ight in the instrument
panel
The a irbag system is monitored ele ct ron ically
to make certain it is functioning proper ly at a ll
times. Eac h time you t urn on the ignition, the
a irbag system indicator light will come on for
a few seconds (se lf diagnostics).
The side curtain airb ag is not activated:
- if th e ign it io n is turned off
- i n s ide collisions when t he accelerat ion
measure d by the sensor is too low
- in rear-end co llisions.

have the system inspected immediately
by your authorized Audi dealer .
It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
How side curtain airbags work
Side curtain airbags can work together wi th
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly restrained .

a ir bags o n the left side
The side curtain airbags inflate between the
occupant and the windows on the s ide of the
vehicle that is struck in a side coll is ion
Q fig . 215 .
When the system is triggered , the side curta in
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG labe l. In or­
der to he lp p rovide this additional protection,
the side curta in a irbag m ust in flate withi n the
blink of an eye at ve ry high speed and with
great fo rce. The side curta in a irbag could in ­
jure you if your seating posit io n is not proper
or upright or if items are located in the area
where the supplemental side curta in a irbag
inflates. This applies especially to ch ildren
¢ page 203.
Although they are not a soft p illow, side cur ­
ta in ai rbag s can "cushion" the impact and in
th is way they can help to reduce the risk of in­
jury to the head and the upper part of the

204 Child Saf ety
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
ch ild safety seat on the front passenger
seat in exceptiona l circumstances and
the
PAS SENGER AIR BA G OFF light does
not come on and stay on, immed iately
install the rear-facing child safety seat in
a rear seating posit ion and have the air­
bag system inspec ted immediately by
yo ur Audi dealer.
_& WARNING
If, in exceptional c ircumstances, you mus t
install a forward -facing child restra int on
the front passenger's seat:
- Always make su re the forward-fac ing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the man ufacturer's in­
struct ions provided with the child safety
seat or carrier.
- Always move t he passenger seat into its
rearmost position in the seat 's fore and
aft adjustment range, as far away from
the a irbag as poss ible before installing
the ch ild restraint. The backrest must be
adjusted to an upr ight position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always rep lace child rest raints that were
installed in a vehicle during a crash. Dam­
age to a child rest raint that is not visible
could cause i t to fail i n another collisio n
si tua tion.
Advanced front airbag system and
children
Your veh icle is equipped with an "Advanced
A irbag System" in compliance w ith United
States Federal Motor Vehicle Safety Standard (FMVSS) 208 as applicable at the time you
r
vehicle was manufacture d.
T he Adv anced Airbag system in yo ur vehicle
has been certified to mee t the "low-risk" re­
quirements for 3-and 6-year old children on
the passenger side and sma ll adults on the
drive r side. The low r is k dep loyment cr iteria
are intended to red uce the risk of in jury
through interact ion w it h the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the a irbag inflates . In addition, the syst em
has been ce rtified to comply wit h the "sup­
pression" re quirements o f th e Safety Sta nd­
ard, to t urn off the fron t airbag for infan ts up
to 12 months who are res trained on the front
passenger seat in child restraints that a re list­
ed in the Standard.
E ven though your veh icle is eq uipped wit h an
Advanced Airbag system , a ll children, espe­
cia lly those 12 years and yo unger, should a l­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger side makes the front seat a potentially
dangerous place for a ch ild to ride . The front
seat is not the safest p lace for a ch ild in a for­
ward-fac ing ch ild safety seat. It can be a ve ry
dange rous place fo r an infan t or a large r child
i n a rea rward-f acing se at.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced A irbag System in your vehicle
detects the presence of an infant or child in a
c h ild restra int on the front passenge r seat us­
i ng the weig ht-sens ing mat in the seat cush ­
ion and the sensor be low th e safe ty belt latch

252 Fuel supply and filling your fuel tank
addition, the expans ion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
@ Tips
- Running your engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle w ith the igni­
tion turned on. The fuel gauge may oth­
erwise not ind icate the correct fuel level
after refuell ing.
- Diesel veh icles* are equipped with a die­
sel misfueling protector. It allows the
vehicle to be fueled only w ith a diesel
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector. If this is the case, try turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or
see your authorized Audi dealer or au­
thorized repair facility for assistance.
Unlocking the fuel filler flap by hand
You con open the fuel filler flop by hand if the
power locking system should foil.

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective catalytic reduction,
an urea solution (AdBlue) is injected into the
exhaust system before a nitrogen oxide cata­
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­ proximately 0.5% to 1.2% of the diesel fuel
that is used .
You must refill the Ad Blue or have it ref illed
by your authorized Audi dealer or qualified
workshop as soon as the Ad Blue refill mes­
sage appears in the instrument cluster
¢page 254.
&_ WARNING ~
Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve­
hicle from being started and dr iven.
If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
- Always have the AdBlue tank refilled we ll
before the tank runs dry. .,.
