Adaptive Air Suspension
Adaptive Air Suspension and
Damping
Description
Adaptive Air Suspension and damping can be regulated and they adapt automatically to a request from the
driver and the drivin g situati on at the time.
Adaptive Air Suspens ion is an e lectron ically controlled springing and
damping system. This chass is system makes it eas ie r on the d river by
adapting to the particular situation t hrough imperceptible contro l
processes.
T he
Adapt ive Air Su spen sion component regu lates ground clea rance
depending on vehicle speed, load condition and driver input. Acce le r·
a ting to a speed above a predetermined limi t will make the vehicle
lower itself. On the other hand, driving more slow ly results in the
vehicle raising aga in at spe cific speeds .
Th e
damping component provides individua l contro l of the damping
forces. For example, with damp ing characte rist ics set to provide
greater comfort, damp ing is set som ewhat harder for a br ief period
only as req uired, for example, whe n going around a curve or over
roug h road surfaces as we ll as when bra king.
Settings
Adaptive Air Suspension provides the drive r with the opportu nity to
set the chassis characte ristics also to the ir individual preference.
W ith the dr iv in g m odes

has three chassis sett ings available, ranging from comfort to sporty.

• Whenever you park you r vehicle, always ma ke su re there is
adeq uate clea rance above and below t he ve hicle. The heig ht of the
parked veh icle ca n change as the res ult of temperature fluctuat ions,
c hanges in loa d cond ition and changes in the dr iv ing mode (ground
cleara nce) .
• M ount t he tie-down ch ains/ cables over the r unning s urfa ce
(circumfere nce) of the tires . Never secu re the vehicle by the axle, the
suspension st ruts or the front o r re ar tow line eye . For technical
reaso ns, the pressure in t he suspension struts may change dur ing the
transport and this will adverse ly affect vehicle handling.
• To prevent damage to the vehicle u nderbody, remembe r th at your
veh icle is no t an off- road vehicle, even in the lift mode. The ground
cleara nce is insufficient for this type of operation .

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 98.
-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 231, "Child Safety".
- Sit properly in your seat and make sure that your passen­ gers do the same::::,
page 76, "General recommenda­
tions".
- Fasten your safety belt and wear it properly. Also instruct
your passengers to fasten their safety belts properly
=:> page 197. •
Controls and equip­
ment Safety first Vehicle operation
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 sure to read the important information and heed the WARNINGS for important details about children and Advanced Airbags =:>
page 231.
Even though your veh icle is eq uipped with an Advanced Airbag
System, make certain that all children, especially those
12 years and
younger, a lways r ide in the back seat properly rest rained for the ir age
and size . The airbag on the passenger side makes the front seat a
potentially dangerous place fo r a child to r ide. The front seat is not
the safest p lace for a child in a forward-facing c hild seat . It can be a
very d angerous pla ce fo r an in fant or a ch ild in a rearwa rd-faci ng sea t.
The Advanced Airbag System in your vehicle has been cert ified to
comply with the req uirements of United States Federa l Motor Vehicle
Safety Standard
208 as applicable at the time your vehicle was manu­
factured .
T he S ta n dard requi res the front airbag on the passenger side to be
turned off ("suppressed") if a child up to about one year of age
restra ined in o ne of the rea r-facing or forward -fa cing in fant
restra ints listed in Federa l Motor Vehicle Safety Standard
208 with
w hich the Advanced Airbag System in your ve hicl e was ce rtified has
been installed o n the front passenger seat . For a listing of the ch ild
restraints that were used to certify compliance with the US Safety
Standard=>
page 233 .
The PASSENGER AIR BAG OFF light in the instrument panel tells you
w hen the front Advanced Ai rbag on the passenge r side has been
turned off by the electronic control unit .
Eac h time you t urn on the ign ition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if the front passenger seat is not occupied,
• will stay on if there is a small ch ild or child rest rai nt on the front
passenger seat, •
will go off if the front passenger seat is occup ied by an adult as
registe red by t he weigh t-sens ing ma t:::::>
page 217, "Moni toring the
Advanced Airbag System" .
Th e
PASSENGER AIR BAG OFF light comes on when the control unit
detects a tota l we igh t on the front passenger seat t hat req uires the
front airbag to be turned off.
If the total we ight on the front passenge r sea t is more than that of a
typical 1 year-old child but less than the weight of a small adu lt, the
front ai rbag on the passenger side can dep loy (the
PASSENGER AIR
BAG OFF
lig ht does not come on). If the PASSENGER AIR BAG OFF
light does not come on, the fro nt airbag on the passenger side has
not been tu rned off by the e lectro nic cont rol u nit and can deploy if
the cont rol unit senses an impact that meets the conditions stored in
its memory.
Fo r example , the a irbag may deploy if:
• a small child that is heavier than a typical 1 year-old child is on the
front passenge r seat (regard less of whet her the child is in one of the
child seats listed:::::>
page 233), or
• a chi ld who has outgrown ch ild restra ints is o n the front passenger
seat.
If the fron t passenger a irbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster and stays on.
Th e front a irbag on the passenger side may
not dep loy (the
PASSENGER AIR BAG OFF li ght does not illum inate and stay lit) even
if a small ad ult o r teenage r, or a passenger who is not sitting upright
w it h th e ir back against a non-recli ned backrest w it h their feet on the
veh icle floor in front of the seat is on the front passenger seat
=>
page 188, "Prope r seat ing pos ition for the dr ive r".
If the front passenger airbag deploys, the Federal Standard requires
t he airbag to meet the " low risk" deployment criteria to red uce the
r isk of injury through interaction with the airbag. "Low risk" deploy­
ment occurs in those crashes that ta ke place a t lower decelerations as
defined in the elec tronic control unit:::::>

Airbag system -----------------=--=---
& WARNING (co ntinued )
• Airbag work most effectively when used with properly worn
safety belts .
• Therefore, always wear your safety belts and make sure that
everybody in your vehicle is properly restrained .
& WARNING
A person on the front passenger seat, especially infants and small
children, will receive serious injuries and can even be killed 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 pa ssenger 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 Sy stem 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
pas senger 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 alway s ride in the back properly re strained for
their age and size. •

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a collision.
The 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 199, "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 i nstr uctions to be s ure
t he seat is right for your child's size
=> page 234, "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

nt of importa nt info rmation, we cannot repeat i t all he re. 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 posi tions 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 ins talled 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.

ESP is des igned to help you maintain vehicle control in s ituations
where the car approaches the limits of "grip", especia lly when accel­
erat ing and cornering. ESP reduces the risk of skidd ing and imp roves
stability under all road conditions.
Th e system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integrated in the elec­
tronic stabilizatio n pro gram. In addition to the data provided by
these funct ions, the ESP control unit requires additional measure­

& WARNING

You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans ­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat,
premature wear and increased stopping di stan ce.
• Under certain climatic and operating conditions such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brakes can be reduced. In winter,
ice can accumulate on the brake pads , linings, discs and drums .
Carefully apply brakes for a test . 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 also affect braking efficiency. Clean
off accumulated salt coating from brake discs and pads with a few
careful brake applications.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the 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 increased stopping di stance . Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop .•
