OP-eration
The supply of a ir to the outlets is controlled either automat ically or
manually depend ing on the operation mode selected. The airflow
from all outlets can be heated, unheated or cooled .
The heater outlets for the rear footwells are located under the front
seats. When you select outlets@, air is also directed to the rear foot­
wells.
[I) Tips
• When defrosting/defogging the windows, air flows from outlets
(D ,@ and @. To defrost or defog the windows as rapidly as poss ible,
air outlets ® should be opened
fully with the adjuster wheels.
• When the air conditioner is working, cooled air w ill flow primarily
from outlets @,® and @. To assure adequate cooling, outlets ®
and © should never be completely closed.•
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should use
the air conditioner only when necessary. Also please note the
following points:
- If you want to save fuel, switch off the air conditioner .
- If you are going to drive with the windows open, switch off
the air conditioner.
By reducing the amount of fuel you use, you also reduce the amount
of polluta nts emitted into the air. •

Driving Safely ---------------------"~'---
Important things to do before driving
Safety is everybody's job! Vehicle and occupant safety
always depends on the informed and careful driver.
For your safety and the safety of your passengers, before
driving always:
- Make sure that all lights and signals are operating
correctly.
- Make sure that the tire pressure is correct.
- Make sure that all windows are clean and afford good visi-
bility to the outside.
- Secure all luggage and other items carefully::::>
page 91.
-Make sure that nothing can interfere with the pedals.
- Adjust front seat, head restraint and mirrors correctly for your height .
- Instruct passengers to adjust the head restraints according to their height.
- Make sure to use the right child restraint correctly to
protect children ::::,
page 167, "Child Safety".
- Sit properly in your seat and make sure that your passen­ gers do the same::::,
page 73, "General recommenda­
tions".
- Fasten your safety belt and wear it properly. Also instruct
your passengers to fasten their safety belts properly

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted .
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road::::,,& . There­
fore:
Do not let yourself be distracted by passengers or by using
a cellular telephone.
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used.•

Child restraints on the front seat - some
important things to know
- Be su re to re ad t he i mpo rt a nt i nfo rmation a nd head the
WA RNINGS fo r i mporta nt details about chil dre n and
Advanced Airbags ~
page 167.
Even t hough your ve hicle is eq uipped with an Advanced Airbag
System, ma ke ce rtain that a ll chi ld ren, especia lly those 12 years an d
younger, always r ide in the back seat prope rly rest rained fo r th eir age
and si ze. The airbag on the passenger side makes the front seat a
po tentially da ngerous place fo r a child to r ide. The fro nt seat is not
the safest place for a ch ild in a forward-facing child safety seat. It can
be a very dange rous place fo r an i nfan t or a child in a rearward-fac ing
seat.
Th e Advanced Ai rbag System in your vehicle has been cer tified to
comply with the req uirements of Un ited States Federa l Moto r Veh icle
Sa fety Standard 208 as applicable at the time your vehicle was manu­
factured.
The Standard requires the front airbag on the passenger side to be
tu rne d off ("s uppressed") if a c hild up to abou t one ye ar of age
restra ined in o ne of the rear -facing or forward -fac ing infant
restra ints listed in Federa l Moto r Vehicle Safety Standard 208 with
whic h the Advanced Airbag System in yo ur vehicle was cert ified has
been installed on the front passenger seat. For a listing of the ch ild
restra in ts that were used to certify compliance with the US Saf ety

The PASSENGER AIR BAG OFF ligh t in th e in st rume nt p anel t ells you
when the front Advanced A irbag on the passenger side has been
tur ned off by the ele ct ronic con trol uni t.
Each time you t urn on the ignition, t he

T he
PASSENGER AIR BAG OFF light comes o n when t he control unit
de tects a total weight on t he front passenger seat that req uires the
front airbag to be t urned off .
If th e total weight o n the front passenger seat is more than th at of a
typical 1 year-o ld child but less than the weight of a small adult, the

light does not come on, the front airbag on the passenger side has
not been turned off by the electronic co ntrol unit and can deploy if
the control unit senses an impact t hat meets the conditions stored in
its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year -old child is on the
front passenger seat (regard less of whether the chi ld is in one of the
child safety seats listed =>
page 169), or
• a child who has outgrown child restraints is on the front passenger

& WARNING (conti nued)
• Airbag work mo st effectivel y when us ed with p roperly worn
safety belts .
• Therefore, always wear your safety belts and make sure that
everybody in your veh icle is properly restrained .
& WARNING
A person on the front passenger seat , especially infants and small
c hildren, will receive seriou s injuries and can even be killed by
being too close to the a irbag when it inflates.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger a irbag 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 conceivable situations that may happen during
the useful life of your vehicle.
• The Advanced Airbag System can deploy in a ccordance with the
" low risk" option under the U.S. Federal Standard if a child that is
hea vier than the t ypical one-year old child is on the front
passeng er seat and the other condition s for airbag deployment
are met.
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position .
• For their own safety, all children , especially 12 years and
younger, should always ride in the back properly res trained for
their age and size. •
Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in

& WARNING (conti nued)
• Never recline the front passenger's seat to transport objects.
Items can also move into the area of the s ide airbag or the front
airbag during braking or in a sudden maneu ver. Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined .
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other br eathing
conditions.
• To reduce the risk of breathing problems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the veh icle or opening windows or doors.
• If you are in a colli sion in which airbags deploy, wa sh your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches.
• If the residue should get into your eyes, flush them with
water .•

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a collision.
Th e physical pr in ci ples o f wha t happens w hen yo ur vehicl e is in a crash
app ly a lso to children=>
page 137, "What happens to occupants not
wearing safety be lts?". But unlik e adu lts and teenagers, the ir
muscles and bones are not fully developed. In many respects c hildren
are at greate r risk of ser io us injury in cras hes than adults .
Because children 's bodies a re not f ully deve loped, they require
restraint systems especially designed fo r their size, weight, and body
st ruct ure. Many cou ntries and all states of t he Unite d States and
prov inces of Canada have laws req uiring the use of approved ch ild
restrain t sys tems for infan ts an d sm all ch ild ren .
I n a fronta l crash at a speed of 20 -35 mph (30-56 km/h) the forces
act ing o n a 13- pound (6 kg) infant w ill be more than 20 times the
we ight of the ch ild . This means the we ight of the child wo uld
suddenly be more than 260 po unds (120 kg). Unde r these conditions,
only a n app ropr iat e child restra int proper ly used can red uce the risk
of serious injury. Child restraints, like adult sa fety be lts, must be used
pro perl y to be effective. Use d imprope rly, they can i ncrease t he ris k
of serious injury in an accident.
C onsult the ch ild safety seat manufacturer's instruc tion to be s ure
t he seat is right for your child's size
=> page 170, "Importa nt safety
instructions for using ch ild safety seats" . P lease be sure to read and
heed all of the impo rtant informat io n and WAR NIN GS about child
safety, Advanced Airbags, and the insta llation of ch ild rest raints in
t his chapte r.
There is a lot you need to know about the Advanced Airbags in your
vehicle and how t hey wo rk when inf ants and childre n in child
restra ints are on the front passenger seat. Beca use of t he large
Controls and equip­

amou
nt of importa nt info rmation, we cannot repeat i t all here . We
urge you to read the detailed information in th is owne r's man ua l
abou t airbags and t he Advanced A irbag System in your vehicle and the
very important information abo ut transporting c hildren on the front
p assenger se at. P lea se be sure to heed the WARNIN GS - they a re
extremely important for your safety and the safety of your passe n­
gers, especially infan ts and small ch il dre n.
& WARNING
• Accid ent statisti cs have shown that children are generally safer
in the rear seat area than in the front seating position. Always
re strain any child age 12 and under in the rear.
• All vehicle occupants and especially children must be
restrained properly when ever riding in a vehicle. An unre strained
or improperly restrained child could be injured by striking the
interior or by being ejected from the vehicle during a sudden
maneuver or impact. An unrestrained or improperly rest rained
child is also at greater risk of injury or death through contact with
an inflat ing airbag .
• A suitable child restraint properly installed and used at one of
the rear seating pos itions provides the highest degree of protec­
tion for infants and small children in most accident situations.
& WARNING
Children on the front seat of any car even with Advanced Airbags
can be seriously injured or even killed when an airbag inflates. A
c hild in a rearward -facing child safety seat in stalled on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflate s.
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will sma sh the child safety seat and
child against the backrest, center armrest, or door . •

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieva l after an accident or crash event. ED R's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic contro l modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period 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 well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General
The Electronic Stability Program increases driving
stability .
With ESP, contro l over the vehicle is increased in situations when the
vehicle is close to the limits of grip, such as dur ing accelerat ion and in
curves. ESP reduces the risk of sk idding and improves vehicle stability
unde r all road conditions.
It operates at all speeds.
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDS) and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
How ESP works
The ESP control unit processes the following data from high-sensitive
sensors: the rotationa l speed of the vehicle about its vertical axis,
fore-and -aft and lateral acceleration forces, brake pressure and
steering angle .
Us ing stee ring ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior. If the two do not match, for example when
the vehicle beg ins to skid, ESP brakes the appropriate whee l auto­
matically.
The vehicle is stabilized aga in by the forces act ing on the whee l
during braking. With an oversteering veh icle (tendency for the rear
end to skid out of the curve), the brake app lication is mainly at the
front wheel on the outside of the curve, with an understeering vehicle
(tendency to run wide in the curve) at the rear wheel on the insid e of
the curve or additionally at the other wheels as needed. This brake
application is accompanied by noises. _,

'-----------------------------------------------
& WA RNING (conti nu ed )
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
pa ssing through water, dr iving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Carefully apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can al so affect br aking efficiency. Clean
off accumulated salt coating from brake disc s and pads with a few
careful brake applic ations.
• If you damage the front spoiler , or if you in stall a different
spoile r, be sure the air flow to the front brakes is not obstructed.
Otherwi se th e brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an inc reased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop .
.J
Brake booster
T h e brake booste r adds ext ra braking p ower.
The brake booster works with vacuum pressure which is created on ly
w hen the eng ine is ru nnin g=>&.
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake boo ster i s not working , for example when towing
your veh icle , or because the brake booster has somehow been
& W ARNING (continued )
damaged , the brake pedal must be p ressed considerably harder to
make up for the la ck of booster assi stan ce. •
Functioning of Anti-Lock Brake System
{ABS)
ABS prevents the wheels from l ockin g up under br aking.
Th e ABS contr ibutes effectively to vehicle co ntrol s ince it prevents t he
w heels from
locking when the brakes are applied . This means that the
veh icle rema ins steerable and is less likely to skid .
With ABS you do not need to pump the brake. Just hold the brake
pedal down .

speed and tends to loc k, t he ABS automatically reduces brake pres­

s light vibration of
the bra ke pedal and some noises to a lert you that vehicle speed must
be adapted to ex isting road and traffic co nditions .
