Adaptive Air Suspension
Adaptive Air Suspension and
Damping
Ap plies to veh icles: w ith Ad aptive Ai r Suspens ion
Description
Adaptive Air Suspension and damping can be regula ted
and they adapt automatically to a request from the
driver and the driving situation at the time .
Adaptive Air Suspension is an e lectron ically controlled springing and
damping system . This chass is system makes it eas ie r on the driver by
adapting to the particular situation th rough impe rceptible contro l
processes .
The
Adaptive Air Suspension component regu lates ground clearance
depending on ve hicl e speed, load cond ition and driver input.
W hen the system is in a utomatic mode, accelerat ing to a speed above
a predete rm ined limit will make the vehicle lower itsel f. On t he othe r
hand, driv ing more slowly res ults in the vehicle ra is ing again at
specific speeds.
Th e
damping component provides individua l control of the damping
forces. For example, with damp ing characterist ics set to provide
greater com fort, damp ing is se t somewhat harder for a br ief period
only as required, for example, whe n going around a curve or over
rough road sur faces as we ll as when braking .
Settings
Adaptive Air Suspension prov ides the drive r wi th t he opportu nity to
set the chass is characterist ics also to their individual preference.
W ith the driving modes
Comfort, Automatic an d Dynamic the dr ive r
has three chassis sett ings available, ranging from comfort to sporty.
In addit ion,
Lift p rovides a fourth mode which can be selecting fo r
dr iving over poor stretches of road =>
page 169, "Chass is controls" . The modes are set
in MM I =>
page 169.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuation s or changes in load .
0 Note
• Whenever you park yo ur vehicle, always make sure there is
adeq uate clearance above and below the ve hicle . T he heig ht of the
parked vehicle can change as the res ult of temperature fluctuations,
chang es in load condition and changes in the dr iv ing mode (ground
clearance).
• If the veh icle is be ing transported (e .g. by tow truck, train, ship,
etc.) , mount the tie-down cha ins/cables over the r unning s urface
(c ircumfere nce) of the tir es. Never sec ure the ve hicle by the ax le, the
suspension struts or the front or rea r tow line eye. For technical
reaso ns, the p ressure in t he suspension st ru ts m ay change dur ing the
transport, w hic h could result in the vehicle no longer being secured
pro perly.
• To prevent damage to the vehicle underbody, remember that your
veh icle is no t an off-roa d veh icle, even in the "lift" mo de. Th e ground
clearance is insufficient for this type of 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.•

-Driving Safely 1---- ---:!....::..-=....:...'=.::,!.._ _______________________ _
& WARNING (continued)
• Always make sure that there are at least 10 inches (25 cm)
between the front passenger's breastbone and the instrument
panel.
• Each passenger must always sit on a seat of their own and
properly fasten and wear the safety belt belonging to that seat.
• Before driving, always adjust the front passenger seat and
head restraint properly.
• Always keep your feet on the floor
in front of the seat. Never
rest them on the seat, instrument panel, out of the window, etc.
The airbag system and safety belt will not be able to protect you properly and can even increase the risk of injury in a crash.
• Never drive with the backrest reclined or tilted far back! The
farther the backrests are tilted back, the greater the risk of injury
due to incorrect positioning of the safety belt and improper
seating position.
• Children must always ride in child safety seats=>
page 219.
Special precautions apply when installing a child safety seat on
the front passenger seat=>
page 197. •
Proper seating positions for passengers in
rear seats
Rear seat passengers must sit upright with both feet on
the floor consistent with their physical size and be prop­
erly restrained whenever the vehicle is in use.
To reduce the risk of injury caused by an incorrect seating
position in the event of a sudden braking maneuver or an
accident , your passengers on the rear bench seat must
always observe the following :
- Make sure that the seatback is securely latched in the
upright position ~
page 83.
-The rear head restraints must be raised fully upward when
passengers ride in the rear seats~
page 181.
- Keep both feet flat in the footwell in front of the rear seat.
- Fasten and wear safety belts properly~
page 191.
-Make sure that children are always properly restrained in a
child restraint that is appropriate for their size and age
~ page 219.
& WARNING
Passengers who are improperly seated on the rear seat can be seri­
ously injured in a crash.
• Each passenger must always sit on a seat of their own and
properly fasten and wear the safety belt belonging to that seat.
• Safety belts only offer maximum protection when the seatback
is securely latched in the upright position and the safety belts are
properly positioned on the body. By not sitting upright, a rear seat
passenger increases the risk of personal injury from improperly
positioned safety belts!
• Always adjust the head restraint properly so that it can give
maximum protection. •

• ....__D_ r_iv _i_ n_, g=-- S_ a _ f_e _,Ly _ ______________________________________________ _
The following bulletins list only some sample positions that will
increase the risk of serious injury and death. Our hope is that these
examples will make you more aware of seating positions that are
dangerous.
Therefore, whenever the vehicle is moving:
• never stand up in the vehicle
• never stand on the seats
• never kneel on the seats
• never ride with the seatback reclined
• never lie down on the rear seat
• never lean up against the instrument panel
• never sit on the edge of the seat
• never sit sideways
• never lean out the window
• never put your feet out the window
• never put your feet on the instrument panel
• never rest your feet on the seat cushion or back of the seat
• never ride in the footwe ll
• never ride in the cargo area
& WARNING
Improper seating positions increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants stay in a proper
seating position and are properly restrained whenever the vehicle
is being used. •
Pedal area
Pedals
The pedals must always be free to move and must never
be interfered with by a floor mat or any other object.
Make sure that all pedals move freely without interference and that
nothing prevents them from returning to their original positions.
Only use floor mats that leave the pedal area free and can be secured
with floor mat fasteners.
If a brake circuit fails, increased brake pedal travel is required to bring
the vehicle to a full stop.
& WARNING
Pedals that cannot move freely can cause loss of vehicle control
and increase the risk of serious injury .
• Never place any objects in the driver's footwell. An object could
get into the pedal area and interfere with pedal function. In case
of sudden braking or an accident, you would not be able to brake
or accelerate!
• Always make sure that nothing can fall or move into the
driver's footwell. •
Floor mats on the driver side
Always use floor mats that can be securely attached to
the floor mat fasteners and do not interfere with the free
movement of the pedals.
- Make sure that the floor mats are properly secured and
cannot move and interfere with the pedals~& .

________________________________________________ D_ r_ i_ v _i_n ""'g "-- S_a_ f_ e_ l _,,y'-- __
Use only floor mats that leave the pedal area unobstructed and that
are firmly secured so that they cannot slip out of position . You can
obtain suitable floor mats from your authorized Audi Dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners.
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera­
tion of your vehicle in other ways .
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
• Always make sure that floor mats are properly secured.
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle.
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped under the brake pedal and accelerator pedal causing a loss of
vehicle control. •

in. WARNING
Always make sure that the doo rs , all windows, the power roof*
and the rear lid are securely clo sed and locked to reduce the risk of
i njury when the vehicle is not be ing used.
• After closing the rear lid, always make sure that it is properly
closed and locked.
• Never leave your vehicle unattended especially with the rear lid
left open. A child could c rawl into the vehicle through the luggage
c ompartment and clo se the rear lid becoming trapped and unable
to get out . Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never l et pa ssengers ride in the luggage compartment. Vehicle
occupants must always be properly restrained in one of the
vehicle 's seating positions .

Tie-downs
The luggage compartment is equi pped with f our tie­
downs to secur e luggage and other items.
Use the t ie-downs to sec ure yo ur cargo prope rly => page 183,
"Load ing the luggage compartment" .
In a co llision, the laws of physics mean that even sma ller items that
are loose i n the vehicle will become heavy m issiles t hat can c ause
serious injury. Items in the vehicle possess energy wh ich vary w ith
vehicle speed and the we igh t o f the i tem. Vehi cle spee d is t he m ost
significant factor.
For examp le, in a frontal coll ision at a spee d of 30 mph (48 km/h),
the forces acting on a 10- lb (4 .5 kg) object are abo ut 20 times the
normal weight of the item . T his means that t he weight of t he item
wou ld s uddenly be abo ut 200 lbs. (90 kg). You can imagine the inju­
r ies that a 200 lbs . (90 kg) item flying free ly throug h the passenge r

& WARNING
Weak, damaged or improper straps used to secure items to tie­
downs can fail during hard braking or in a collision and cause
serious personal injury .
• Always use suitable mounting strap s and prope rly secure items
to the tie -downs in the luggage compartment to help prevent
items from shifting or flying forward as dangerous missiles.
• When the rear seat backrest is folded down, always use suit­
able mounting straps and properly secure items to the tie-downs
