Adaptive Air Suspension
Adaptive Air Suspension and
Damping
A pplies to vehicles: wi th Adap tive Air Suspens ion
Description
Adaptive Air Suspension and damping can be regulated
and they adapt automatically to a request from the driver
and the driving situation at the time.
Adaptive Air Suspension is an electronically controlled springing
and damping system . This chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Adaptive Air Suspension component regulates ground clear
ance depending on vehicle speed, load condition and driver input.
When the system is in automatic mode, accelerating to a speed above a predetermined limit will make the vehicle lower itself. On
the other hand, driving more slowly results in the vehicle raising again at specific speeds.
The
damping component provides individual control of the
damping forces. For example, with damping characteristics set to
provide greater comfort, damping is set somewhat harder for a brief
period only as required, for example, when going around a curve or
over rough road surfaces as well as when braking.
Settings
Adaptive Air Suspension provides the driver with the opportunity to
set the chassis characteristics also to their individual preference.
With the driving modes
standard, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty .
In addition,
lift provides a fourth mode which can be selecting for
driving over poor stretches of road :::::,
page 185, "Chassis controls". The modes are set in
MMI:::::,
page 185.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuations or changes in load.
0 Note
• Whenever you park your vehicle, always make sure there is
adequate clearance above and below the vehicle. The height of the parked vehicle can change as the result of temperature fluctuations,
changes in load condition and changes in the driving mode (ground
clearance!.
• If the vehicle is being transported (e.g. by tow truck, train, ship,
etc.) , mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the vehicle by the axle, the
suspension struts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport, which could result in the vehicle no longer being
secured properly.
• To prevent damage to the vehicle underbody, remember that
your vehicle is not an off-road vehicle, even in the "lift" mode. The
ground clearance is insufficient for this type of operation.
• If you are going to tow a trailer, you must activate the trailer oper
ation mode :::::,
page 186.
[ i] Tips
Before you raising your vehicle using the vehicle jack (for example,
when changing a flat tire) you must activate the jacking mode
=> page 186. •

-Airbag system ----=--a.---------------------------------------
& WARN ING (continued )
• Always make sure that the side airbag can inflate without inter
fe rence :
- Never install seat covers or replacement upholstery over the
front seatback s that have not been spe cifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate .
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi
ately by an authorized Audi dealer .
• The airbag system can be activated only once. After an airbag
ha s inflated , it must be replaced by an authorized Audi de aler or
qualified technician who has the technical information , training
and special equipment necessary .
• The airbag system can be deployed only once. After an airbag
has been deployed , it must be repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• For safety reasons in severe accidents , the alternator and
starter are separated from the vehicle battery with a pyrotechn ic
circuit interrupter.
-Work on the pyrotechni c circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehi cle or the circuit inte rrupter is scrapped , all appli
cable safety precautions must be followed.

Other things that can affect Advanced Airbag
performance
Changing the vehic le 's suspension system can change the way that
t h e Adva nced Ai rbag Syste m performs in a c rash. Fo r example,
using tire -rim combinations not approved by Audi, lowering the
ve hicle, c hang ing the s tif fne ss of the su spe nsio n, in cl ud in g th e
springs, suspens ion struts, shoc k absorbers etc. can change the
f o rce s tha t are m eas ure d b y the air bag senso rs and se nt to the e lec
tronic control unit. Some suspension changes can, for example,
increa se the fo rce levels measured by the senso rs and ma ke the
airbag system dep loy in crashes in which it wou ld not deploy if the
changes had not been made . Othe r kinds of changes may reduce
t h e force lev els measured by the sensors and preve nt the airbag
from dep loying when it sho uld.
T he s ensors i n the safet y be lt buc kle for the driver a nd fr ont
passenger seat tell the e lectronic contro l modu le if the safety belt is
l a tc h ed or not. If the sa fety belt is b eing use d, th e front airbag wi ll
deploy at a slightly higher rate of v ehic le dece leration than if the
safety be lt is n ot be ing use d. T herefo re, i n a partic ular collision, it i s
possible that an air bag wi ll not deploy at a seating position where
the safety be lt i s being used but wi ll inflate at the position whe re the
sa fety be lt is not bei ng used. It is important tha t noth ing i nte rfer e
with the safety belt buckles so that the sensors can send the correct
i nfo rmati on about saf ety belt use to the e lectr onic co ntrol unit. .,.

Operating instructions
Max im um tra iler weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer.
T ra ile r l oa d di stributio n
Be sure the load in the trailer is he ld securely in place to prevent it
from shifting forward, backward or sideways .
Never allo w a passe nger to r ide in a tr aile r~ & in "Driving instruc
tions" .
Engin e c oolin g sys te m
Towing a trailer makes the eng ine work harder. It is important that
the cooling system's performance is up to the additiona l load. Make
sure that the coo ling system has enough fluid .
Tire pr ess ure
When towing a trailer, inflate the tires of your vehicle to the co ld tire
pressure listed under "Full load" on the labe l located on the driver's
side B -pillar {visible when the door is open). Inflate trailer tires to
trailer and tire manufacturers' specifications .
Light s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Safe ty chains
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave e nough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the r oad when you a re driving .
The chains should cross under the tra iler tongue to prevent it from
dropping in case of separation from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
- Do not tow a loaded trailer when your car itself is not
loaded.
Be espec ia lly careful whe n passing other vehicles.
- Observe s peed l imits .
Do not drive at the maximum permiss ible speed .
Always apply brakes ear ly.
Moni tor t he temperature ga uge.
Weight distr ibution
Towing a loaded trailer with an empty car results in a highly
unstable distr ibution of weight. If this cannot be avoided, drive at
very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and perm is
s ib le, while keeping the trailer as light as possib le under the circum
stances . Whenever possible, transfe r some cargo to t he luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considera tions . .,

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
~ page 349.
in. WARNING
Ne w tire s or tire s that are old , worn or damaged cann ot pro vide
m aximum cont rol and braking ability.
• New tire s tend to be slippe ry and m ust be broken in . To redu ce
the risk of losing control, a colli sion and seriou s per sonal injurie s,
drive with speci al care for t he fi rst 350 m ile s ( 560 km l.
• Driving with worn or damaged t ire s can lead to lo ss of co ntrol ,
s udd en tire failure , in clu ding a blowout a nd sudden deflation , .,,_
Vehicle care
I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• 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
low speed.

& WARNING (continued)
• 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 failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than

Uniform Tire Quality Grading
is a tire information system developed by the United States National
Highway Traffic Safety Adm inistration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is
not a safety rati ng and not a guarantee that a tire will last for a
prescribed number of miles or perform in a certain way . It simply
gives tire buyers additiona l information to comb ine with other
