Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants .

Fig. 113 Location of front passe nger's ai rb ag : in the in­
strument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured . The safety belts
for the front seats have "pretensioners" that
help to take slack out of the belt system. The
pretensioners are also activated by the elec­
tronic control unit for the airbag system.
The front safety belts also have load limiters
to help reduce the forces applied to the body
in a crash .
The airbag for the driver is in the steering
wheel hub¢
fig. 112 and the airbag for the
front passenger is in the instrument panel
¢fig. 113. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the
Airbag system 113
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature .
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in ­
fants and small children.
A WARNING ,.;;
Never rely on airbags alone for protection .
- Even when they deploy, airbags provide
only supplementa l protection.
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your ve­
hicle is properly restrained.
A WARNING
A person on the front passenger seat, es­
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates .
- Although the Advanced Airbag System in
your vehicle is designed to turn off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special
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 condit ions for airbag de­
ployment are met.
- For its own safety, a child should always
ride properly restrained for its age and
size.

States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured .
The front Advanced Airbag Sys tem supp le­
ments the safety belts to provide additional
protection for the driver's and front passeng­
er 's heads and upper bodies in fronta l crashes.
The airbags inflate only in fronta l impacts
when the vehicle dece lerat ion 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 veh icle.
A lways remember that the airbag system ca n
only help to protect you, if you are s itting up­
right, wearing yo ur safety belt and wea ring it
p roperly. This is why you and you r passenge rs
must always be properly restr ained , not just
beca use the law requires you to be.
The Advanced Airbag System i n your veh icle
has been cer tified to meet the " low r is k " re­
qu iremen ts for
3 an d 6 year-o ld childre n on
the passenger side and very small adu lts on
the driver side. The low risk deploymen t crite ­
ria are intended to he lp red uce the risk of in­
jury through interaction with the front airbag that can occur, for example, by be ing too
close to the steer ing whee l and instrument
panel when the airbag i nflates .
In addition, the system has been certif ied to
comp ly w ith the "suppression" requ irements
of the Safety Standard, to tur n off the front
a irbag for infants
12 months old and younger
who a re restra ined on the front passenger
seat in c hild restra ints that a re listed in the
St anda rd ¢
page 132, Child restraints and
Advanced Airbags.
"Suppression" requires the front airbag on the passenger side to be turned off if :
- a ch ild up to about one year of age is re­
stra ined on the front passenger seat in one
of the rear-facing or forwa rd-fac ing infa nt
rest raints listed in Federa l Motor Veh icle
Safety Standard 208 wit h whi ch the Ad­
vanced Airbag System in your vehicle w as
certified . For a list ing of the child rest rain ts t
ha t were used to certify your vehicle 's com ­
pliance with the US Safety Standa rd
¢ page 132,
-weight less than a thres ho ld level stored in
the control unit is detected on the front pas­
senger seat.
When a person is dete cted on the front pas ­
senger seat, weighing more than the tota l
weight of a chi ld that is about
1 year old re­
stra ined in one of the rear-facing or forward­
facing infant restraints ( listed in Federal Mo­
tor Vehicle Safety Standard 208 w it h which
the Advanced Airbag System in your vehicle
was ce rtified), the front airbag on the passen­
ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
whe n the electro nic con trol unit detects a to­
ta l we ight on the front passenger seat that re­
quires t he front airbag to be tu rned off. If t he
PASSENGER AIR BAG OFF ligh t does no t
come o n, the fron t airbag on the passenger
s ide has not been turne d off by the cont ro l
u nit and can dep loy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight on the front passenge r
seat is more than that of a typica l
1 year-old,
but less than the we ight of a small ad ult, the
front a irbag on the passenger side may dep loy
(the
PASSENGER AIR BAG OFF light does not
come on).
For example , the airbag may deploy if:
- a small ch ild that is heav ier t han a typic al 1
yea r-old ch ild is on the front passenger seat
(regard less of whethe r the child is in one of
the child safety seats listed
¢ page 132),
-a child who has outgrown ch ild restraints is
on the front passenge r seat .
If the fron t passenger a irbag is turned off, the
PASSENGER AIR BAG OFF ligh t in the cen ter
of the ins trument panel will come on and stay
o n.
T he front airbag on the passenge r sid e may
not dep loy (the PASSENGER AIR BAG OFF
li ght does not illuminate a nd stay lit) i f:

-The inflating airba g will hit the child
safety seat or infant carrier wit h great
f o rce and w ill smash t he ch ild safety seat
and child aga inst the backrest, center
arm rest, d oor or roof.
- Never install a r earward facing child
sa fety seat on the front pass eng er s eat
unless the
PASSENGER AIR BAG OFF
light c omes on and stays on. If the PAS­
S ENGER AIR BAG OFF
ligh t does no t
come on and stay on, the inflating airbag
will hit the child safety seat or infant car­
rier with great force and will smash the
child safety seat and child against the
backrest, door or roof. Have the airbag
system inspected immediately by your
authorized Audi dealer .
A WARNING
Objects between you and the a irbag 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 a irbag
inflates.
- Never hold th ings in your hands or on
your lap when the vehicle is in use .
- Never transport items on or in the area
of the front passenge r seat. Objects
cou ld move into the area of the front air­
bags dur ing braking or other s udden ma­
neuver and become dangerous projec ­
ti les that can cause serious personal in­
jury if the airbags inflate.
- Never place o r attach accessories or oth­
er objects (such as cup ho lders, tele­
phone brackets, large, heavy or b ulky ob­
jects) on the doors, over or near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those a reas 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 in to the area of the side airbag or
the front airbag dur ing braking or in a
sudden maneuver . Objects near the air -
-
Airbag system 119
bags can become projectiles and cause
inju ry, partic ularly when the seat is re­
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r other respiratory
conditions shou ld get fresh air r ight
away by getting o ut of the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, was h your hands and fa ce with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any cuts or sc ratches .
- If the resid ue should get into your eyes,

130 Child Safety
Child Safety
Important things to know
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
c::> page 102, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not
fully developed . In many respects children are
at greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully devel­
oped, they require restraint systems especial ­
ly designed for their size, weight, and body
structure . Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re­
straint systems for infants and small children.
In a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more than 20 times the
weight of the child. This means the weight of
the child would suddenly be more than 260 pounds (120 kg). Under these conditions,
only an appropriate child restraint properly used can reduce the risk of serious injury.
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp­
erly, they can increase the risk of serious in­
jury in an accident.
Consult the child safety seat manufacturer's instructions in order to be sure the seat is
right for your child's size
c::> page 133, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about child safety, Advanced Airbags, and the
installation of child restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they
work when infants and children in child re­
straints are on the front passenger seat. Be­
cause of the large amount of important infor- mation, we cannot repeat it all here. We urge
you to read the detailed information in this
owner's manual about airbags and the Ad­
vanced Airbag System in your vehicle and the
very important information about transport­ ing children on the front passenger seat.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small children.
A WARNING
-
All vehicle occupants and especially chil­
dren must be restrained properly whenev­
er riding in a vehicle. An unrestrained or
improperly restrained child could be in­
jured by striking the interior or by being
ejected from the vehicle during a sudden maneuver or impact. An unrestrained or
improperly restrained child is also at great­
er risk of injury or death through contact
with an inflating airbag.
_& WARNING
Children on the front seat of any car even
with Advanced Airbags can be seriously in­
jured or even killed when an airbag in­
flates. A child in a rearward-facing child
safety seat installed on the front passen­
ger seat will be seriously injured and can
be killed if the front airbag inflates.
- 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, door or roof.
- Never install a rearward facing child
safety seat on the front passenger seat
unless the
PASSENGER AIR BAG OFF
light comes on and stays on. If the PAS·
SENGER AIR BAG OFF
light does not
come on and stay on, have the airbag
system inspected immediately by your
Audi dealer.

Intelligent technology
Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle go ing in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works togethe r with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
""Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over-
Driving and environment 153
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
Audi dealer helps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

168 Checking and filling
oils available today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­
based engine oil, the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine
running smoothly and help prevent the for­
mation of harmful deposits, sometimes called
"sludge," that over t ime can lead to expensive
repairs .
At the time of printing, engine oils available in
the U .S . and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every synthetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the formation of harmful de­ posits use only oil with the following specifi­
cations printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion singly or in combination with other desig­
nations and oil quality standards .
Viscosity
Engine oils are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on climactic or seasonal con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across all tem­
perature ranges for normal driving conditions.
However, if engine oil viscosity grade SAE
5W40 is not available, you can also use viscos­
ity grade SAE 5W-30 or SAE OW-40 as long as
it meets Audi oil quality standard VW 502 00
specifications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that expressly conforms to the VW 502 00 specification, in case you have to
top
off the oil while on the road.
Only if the level of the oil is at or below the
minimum mark on the oil dipstick - and no oi l
that expressly conforms to Audi oil standard
VW 502 00 specifications is available -may
you top
off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3
or API SM specifications, but even then, only
in viscosity grades SAE SW-40, SAE 5W-30, or
SAE OW-40 . However, during the entire time
between oil change intervals, never top
off
with more than a total of 0.5 qt/liter engine
oil that does not conform to Audi oil specifica­
tion VW 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer o r
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa.com or
www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently. Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods.

172 Checking and filling
@ For the sake of the environment
- Before changing your oil , first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine o il collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
q uir es little attention .
The cooling system has been filled at the fac ­
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly condi tioned water and the
manuf acturer 's glyco l-b asedcoolan t addi -
tive G l3 antifreeze with ant icorros ion addi ­
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es­
sary frost protection and p rotects metal com ­
ponents in the engine's cooling system from
corrosion and scaling . It a lso raises the boil­
ing point of the coo lant .
Do not red uce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
l e a st 50 % but not more than 60 %
to main­
tain antifreez e protection and cooling efficien­
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld free ze and damage the veh i­
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa ­
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 165.
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ m ate conditions . This is especia lly impor­
tan t if you live in a reg io n wher e the win ­
t er is ex treme ly col d. If ne cessa ry, i n­
crease the proportion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
