with their feet on the vehicle floo r in front
of the seat is on the front passenger seat .
I f the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to help re ­
d uce the risk of inj ury through interaction
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic co ntrol

To redu ce the risk of injury whe n an airbag
in flates, always wear safety belts prope rly.
- If you are unres trained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You w ill also receive serio us inju ries and

.8, WARNING
-
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser iously injured and can be killed if
the front airbag inflates -even with an Ad­
vanced A irbag System .
- Al tho ugh the A dvanced Airbag Sys tem in
your veh icle is designed to tur n off the
fro nt airbag whe n a rea rward-facing
child res tra int has been insta lled on the
front passenger seat, nobody can abso ­
lutely g uarantee that dep loyment is im­
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The in flating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and chi ld against the backrest , center
armrest, doo r, or roof.
- Always install rearward-facing chi ld re­
straints in the back seat .
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan­

If, in e xceptiona l circumstances, you must
i nstall a forward -facing child restraint on
the front passenger 's seat:
- Always make sure the forward- facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never put the forward-facing child re­
straint up against or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as fa r away from
the airbag as possible, before install ing •

-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened 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 de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
-All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including 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
authorized Audi dealer or qualified work­
shop.
- 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 replace­
ment upholstery over the front seat­ backs that have not been specifically
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 air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must be replaced by an authorized Audi
dealer 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 replaced with new replace-

ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten ­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules

ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi ,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control unit. Some suspension changes can, for

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine power and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of water in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 171
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 173, fig. 166 or~ page 173,
fig. 167. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles with adaptive c ruise control*, the
brake assis t system is more sensitive if the
•
•

172 Intelligent technology
distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other wheels.
This f unct ion is available up to abo ut 60 mph
(100 km/h) .
In extreme cases, ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll switch on aga in a u­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steeri ng*, ESC also
helps to stabilize the stee ring in critical s itua­
tions.
Select ive wheel torque control
Selective whee l torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows mo re prec ise d riving in curves. The
appl icable system may no t activate when d riv­
i ng in wet or snowy condi tions.
A WARNING
- The ESC and its integrated systems can ­
not overcome the laws of physics. This is especia
lly important on slippery o r wet
roads. If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will in crease the r is k of a loss of vehi­
cle control, collision and serious person al
in juries.
- Always adap t your speed to road, traffi c
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC and its integrated sys­
tems cannot a lways p revent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
T he drive w heels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
a ll four wheels are equipped wi th iden ti­
c al tires. D ifferen t tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are workin g.

Braking
What affects braking efficiency?
New brake pad s
Du ring the first 2 50 miles (400 k m), new
b ra ke pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
The break-in period can be considerably lon­
ger for vehicles with ceramic brake rotors*.
You can compensate for this slightly reduced br aking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
b reak-in per iod.
Operating conditions and d riving h abits
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat­
ing conditions and dr iv ing habits ¢.&. . On
vehicles that are e ithe r dr iven mostly in stop­
and-go city traffic o r are driven ha rd, the
b rake pads should be checked by you r aut hor­
iz ed A udi de aler more often than specified in
the
Warrant y & Maintenan ce booklet . Fail ure
to have your b ra ke pads inspected can resu lt
in red uced brake performance.
On steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the eng ine. Th is w ay, you preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
N oises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature a nd h umidity.
Due to the na ture of the mate rials used i n ce­
ramic brake rotors*, noises may become more
apparent at low speeds.
Effect of water and road salt
I n ce rtain situat ions, for exampl e after d riving
throug h wate r, in heavy ra in, after overn igh t
conde nsation or afte r washi ng your c ar, the
b ra ki ng effect can be reduced by moisture or
ice on the bra ke rotors and b rake pads. The brakes must be dr
ied first with a few careful
brake applications .
At highe r speeds and with the winds hield wip­
ers t urned on, the b ra ke pads press against
the b rake roto rs fo r a short amount o f time .
This occurs at regular intervals without the drive r not icing and p rov ides for better brake
response time under wet conditions.
The effectiveness of the brakes can be red uced
whe n the vehicle is driven on a sa lt -covered
road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap­
plicat ions of the bra ke
¢ .&. .
D ue to the ir s urface characteristics, ceramic
brake rotors* absorb moisture in such condi­
tions . T his can cause a temporary reduction in
braking force compared to dry brakes . You can
compensate for th is by pressi ng the brake
p eda l harde r.
Corrosion
There may be a tende ncy for dirt to build up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regu larly or
only for short trips w it h litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros io n has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed ¢.&. .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c::> .&. .
Low brake fluid level
Malfunctions can occur in the brake system if
t h e brake fluid level is too low. The brake flu id
level is monitored electro nically .
Brake boo ster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
on ly when the engine is running

ING S ¢.&._ in Working in the engine compart­
ment on page 195 .
.. Read the brake fluid level from the brake
fluid reservoir
¢ fig . 179 , ¢page 197,
fig . 174.
The brake fluid level must be be ­
tween the "MIN" and
"MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side
¢ page 197.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models:
11111 , Canadian
models :. ) will come on
¢page 15. Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected .
If the
brake fluid level is too low, the brake warn ing/
indicator light w ill illuminate. Contact an au­
thorized Audi dealer
immedi atel y.
@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two year s. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi d ealer . Your dealer has the correct
tools, the right brake fl uid and the know -how
to do this for you .
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake flu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicle Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your

Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged c>
page 207.
Have the battery checked when you take your
ve hicle in for service . You are well adv ised to
replace a battery that is older than 5 yea rs .

24 0 T ire s and wheel s
According ly, when the low tire pressure te ll­
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig­
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons , includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears
