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 167, "Chass is controls" . The modes are set
in MM I =>
page 167.
& 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,
changes 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.
• If you are go ing to tow a trai ler, you mus t activate the trai ler ope r­
ation mode =>
page 168.
[ i ] Tips
Before you raising your vehicle us ing the veh icle jack (for example,
w hen c hanging a flat tire) you must acti va te the j ack ing mode

General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least appreciated and most abused pa rts of a motor
vehicle . Tires are, however, one of the most important parts of a
vehicle , pa rticul arly conside ring the comparat ive ly small patch of
rubber on eac h tire that assures that all-important contact between
you, your veh icle and the road.
Maintai ning t he cor rect tire pressu re, mak ing su re that your veh icle
and i ts tires do not have to carry more weight t han they can safely
hand le, avoid ing damage from road ha za rds and regularly inspecting
tires for damage includ ing cuts, s lashes irregular wea r and ove rall
condi tion a re the mos t important th ings that you can do to help avoid
sudden t ire failure including tread separation and blowouts.
Avoiding damage
If you have to d rive ove r a cur b or sim ilar obstacle, d rive very slowly
and as close as possible at a rig ht angle to the curb .
Always keep chemicals incl ud ing grease, oil, gaso line and brake f luid
o ff t he t ires .
Ins pect the ti res regularly for damage (cu ts, cracks o r blisters, e tc.) .
Remove any foreign bodies embe dded in the treads.
Storing tires
M ark tires w hen yo u remove t hem to indica te t he d ire ct io n of rota ­
tion . This ensures you to be ab le to mount them correctly when you
re insta ll them.
Whe n removed, t he wheels or tires should be sto red in a cool, dry and
preferably da rk p lace.
Safety first
Store tires in a v ertica l pos it io n if they a re not mount ed on rims, in a
hor izonta l posit ion if they are mounted on r ims.
New tires
N ew tires have to be broken in=> & .

Hidden damage
Damage to tires and rims is often not readi ly visible. If yo u notice
unu sual vib ra ti on o r the ve hicle pulls to one side, t his may in dica te
that one of the t ires has been damaged. The tires must be checked
im media tely by an auth oriz ed A ud i d eale r or qual ifie d wor ks hop.
Unidirectional tires
A un id irectional tire can be identified by arrows o n th e sidewall , th at
point in the direct ion the t ire is designed to rotate. You must fo llow
t he s peci fied dire ction o f ro tat io n . This is neces sary so t hat t hese

& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, dri ve with special care for the first 350 miles (560 km).
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately. _..

Incorrect wheel alignment
In correct whee l al ignme nt can ca use excessive tir e wea r, impairing
th e sa fety o f the vehicl e. If t ires show excessive w ear, hav e the w heel
alignment checked by a n authorized A udi dea ler or qualifie d work­
shop.
All Wheel Drive
Vehicles wi th quattro® must always have tires of the same size ,
con st ruct ion an d tread type . For details see~
page 246.
& WARNING
Sudden tire failure can lead to los s of control, a cra sh and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause t ire damage, such as
grease , oil, gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failu re and loss of vehicle control. •

& WARNING (conti nu ed )
• Alway s use tire s, rim s and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinat ions that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
especially at high speed s. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tir es on your vehicle if you are not sure of
their "previous history. " Old used t ires m ay have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern .
Driving with different tire s reduces vehicle handling and can lead
to a loss of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for example w ith winter tires - only use the spare
tire for a short period of time and drive with extra care. Refit the
normal road wheel as soon as safely possible.
• Never drive fa ster than the maximum speed for which the tires
on your vehicle are rated because ti re s that are driven faster than
their rated speed can fail suddenly.
• Overloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properl y inflated
and not over or underinflated.
• For technical reasons it is not always possible to u se wheels
from other veh icles- in some cases not even wheels from the same
vehicle model.
• If you install wheel tr im discs on the vehicle wheels , make sure
that the air flow to the brakes i s not blocked . Reduced airflow to
the brakes can them to overheat, increasing stopping distances
and cau sing a collision.
& W ARNING (continued )
• Run flat ti res may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassi s designed
fo r run flat tires. Inco rrect use of run flat tires can lead to vehicle
damage or accidents. Che ck with an author ized Audi dealer or tire
specialist to see if your vehicle can be equipped with run flat tires .
If run flat tire s are u sed, they must be installed on all four wheels.
M ixing t ire types is not permitted.
0 Note
• For tech nica l reasons, it is not generally poss ible to use the wheel
r ims from o ther veh icles . T his ca n hold t rue for w heels of the same
veh icle type.
• If the sp are tire is different fr om the tires t hat yo u have mo unted
on your vehicle (for example w inter t ires or wide profile tires), then
use the s pare tire for a shor t perio d of tim e on ly and drive wi th ext ra
care. Replace t he flat tire w ith the tire matching the others on your
vehicle as soon as possible.
• Never dr ive witho ut the valve stem cap . The valves could get
damage d.

For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Requirements
in addition to these grades.
Tread wear
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified
government test course .
For example, a tire graded 150 would wear one and one half (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may depart significantly from the norm
due to variations in driving habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C. Those
grades represent the tire's ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete . A tire marked C may have poor trac­
tion performance ~& .
Temperature
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissi­
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure~&.
The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109 . Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law .
Safety first
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice . At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with
very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels. Make
sure you purchase snow tires that are the same size and construction
type as the other tires on your vehicle.
If your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving,
even with the standard tires. However,
we strongly recommend that you always equip all four wheels on your
vehicle with correctly fitted winter tires or all-season tires, when
winter road conditions are expected. This also improves the vehicle's
braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow .
Winter tires (snow tires) must always be fitted on all four wheels .
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire sizes. Use only radial winter tires. ..,_
