Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all w heel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel dr ive, the dr iv in g power is divided be­
tween all four whee ls . T his happens automatical­
ly depending on your driving behavior as well as
the current road conditions . Refer to¢
page 123,
Electronic stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow ­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q ,& .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
braking effect .
Snow chains
If
there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
q page 230, Snow chains.
Replacing tires
For vehicles with all wheel d rive, only wheels wi th
the same rolling circumference should be used.
Avoid wheels with different tread depths
qpage 221.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terra in. Refer to¢
page 259.
_& WARNING ~
-Also, in vehicles with a ll wheel drive, adapt
your driving style to the current road and
traffic cond itions . Do not let the increased
safety provided tempt you into taking risks.
- The braking ability of your veh icle is limited
to the tract ion of the wheels. In th is way, it

in front, side and rear-end collisions of great se­
verity and in a rollover. This tightens the belt and
takes up belt slack¢.&.
in Service and disposal of
safety bel t pretensioner on page 147.
Taking up
the slack helps to reduce forward occupant movement during a collision.
A WARNING
- It is possible for the pretensioners to deploy
incorrectly .
- The pyrotechnic system can only provide protection for one collision . If the pyrotech­
nic pretensioners deploy, the pretensioning
system must be replaced.
(D Tips
The pyrotechnic safety belt pretensioners can
only deploy once .
- The safety belt pretensioners do not deploy
in minor frontal and side collisions, in rear­
end collisions, in rollovers and in collisions
involving very little impact force.
-A fine dust is released when the pyrotechnic
safety belt pretensioners deploy. This is nor­
mal and is not caused by a fire in the vehi­
cle.
- The relevant safety requirements must be
observed when the vehicle or components
of the system are scrapped. A qualified
dealership is familiar with these regulations
and will be pleased to pass on the informa­
tion to you.
- Be sure to observe all safety, environmental
and other regulations if the vehicle or indi­
vidual parts of the system, particularly the
safety belt or airbag, are to be disposed. We recommend you have your authorized Audi
dealer perform this service for you.
Service and disposal of safety belt preten­
sioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, removing,
servicing or repairing of belt pretensioners can
damage the safety belt system and prevent it
from working correctly in a collision.
Safety belts
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
= -
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing a safety belt preten­
sioner from activating when needed or acti­
vating it unexpectedly:
- The belt pretensioner system can be activat­
ed only once. If belt pretensioners have
been activated, the system must be re­ placed.
- Never repair, adjust, or change any parts of
the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Special
procedures are required for removal, instal­
lation and disposal of this system.
- For any work on the safety belt system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified technician
who has an Audi approved repair manual,
training and special equipment necessary .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Material
-special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules safe ­
ty belts with pretensioners are scrapped, all
applicable laws and regulations must be ob­
served. Your authorized Audi dealer is familiar
with these requirements and we recommend
that you have your dealer perform this service
for you.

from the airbag as possible . The backrest
must be adjusted to an upright position .
Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions.
- Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the
PASSENGER
AIR BAG OFF light will stay on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi . Installing, remov­
ing , servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from working properly
in a collision.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
-
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
Airbag system
-Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened with plain water . Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in­
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
- For any work on the airbag system, we strongly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side airbag can inflate without interference:
- Never install seat covers or replacement upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in­
flate.
- 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 deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed 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

nance booklet under
AIRBAG REPLACEMENT
RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter .
- Work on the pyrotechnic circ uit inter rupt­
er must only be performed by a qualified
technicians w ho have the experience, in­
formation and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter is
scrapped, a ll applicable safety precautions
must be followed.
@ For the sake of the environment
Undep loyed airbag modu les and pretension ­
ers might be classified as Perchlorate Materia l
- specia l hand ling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate. W hen the veh icle or parts of the re­
straint system including a irbag modules and
safety belts with prete nsioners are scrapped ,
all applicable laws and regulat ions must be
observed. Your authorized A udi dealer is fa­
m iliar with the se requirements a nd we recom­
mend that you have your dealer perform this
service for yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system ca n
change the way that the Advanced A irbag System
performs in a crash. For example, using t ire- rim
combinat ions not approved by Audi, lower ing the
ve hicl e, chang ing the stiffness of the suspension,
includ ing the spr ings, suspension s truts, shoc k
absorbers etc. can change the forces that are
measured by the a irbag sensors and sent to the
e lectronic control unit. Some suspension changes
can, for example, increase the force levels meas ­
ured by the sensors and make the a irbag system
deploy in c rashes in which it wou ld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
164
the sensors and p revent the airbag from dep loy ­
ing when it shou ld .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components origina lly instal­
led on you r vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbag s
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 132 Driver 's knee a irbag
The driver knee airbag is i n the instrument panel
u nderneath the steer ing wheel ~
fig. 132 , the
airbag fo r the passenger is at abou t the same
height in the i nstr ument panel underneath the

The knee airbag offers additional protection to
the d river's and passenge r's kn ees and uppe r and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front a irbags deploy, the knee a irbags also
deploy in fronta l co llisions when the dep loyment

(D Note
- Methanol f uels which do not meet these re­
quirements may cause corrosion and dam ­
age to plastic and rubber components in the
fuel system.
- Do not use fue ls that fail to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whethe r o r
not a particular fue l blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you sw itch to unb lended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasol ine grades differ from one manu­
facture r to another, they have certa in things in
common . All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas ­
oline. For more information on TOP TIER Deter-
"' gent Gasoline, please go to the off icial webs ite
