On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warn ing/ind icator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicat es that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic co nverter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be
malfunctioning. For more information~
page 29, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate ~

Driver information display
On-Board Diagnostics monitors the components of your emission
control system . Each monitored component in your engine system
has been assigned a code. In case of a malfunction, the component
will be identified and the fault stored as a code in the control module
memory .
The MIL light may also illuminate if there is a leak in the on-board fue l
vapor recovery system. If the light illuminates after a refueling, stop
the vehicle and make sure the fuel filler cap is properly closed
=;, page 271 .
In order to make an accurate diagnosis, the stored data can only be
displayed using specia l diagnostic equipment (generic scan too l for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the hood release=;, fig. 22.
Your authorized Aud i dealer or qualified workshop can interpret the
code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equ ipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of contro l if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating . For more information =;,
page 303.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Lamp (MIL) will illuminate . If this
occurs, contact the nearest authorized Audi dealer for ass istance. .,,_

Speed warning system
Overview
Th e speed war ning syst em helps you to keep your d riv ing
speed below a set speed limit.
Th e speed warning system warns if the dr iver exceeds a prev iously
sto red ma ximum speed. A warning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
same time, a warning symbol appears in t he di sp lay. The symbo l's
appea rance might be different in some models .
T he speed warn ing system has two warnin g thresho lds th at f unctio n
independently of eac h oth er and that have somewhat diffe rent
purposes:
Speed warning 1
Yo u ca n use speed war ning 1 to set the maximum speed wh ile you a re
driving. This setting will remain in effect until you turn off t he igni­
tion , assuming t hat you have not changed or reset t he setting .
T he speed w arnin g symbo l
0 (USA mo dels) /8 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed .
It goes out whe n the speed falls be low the stored max imum s peed.
T he speed warning symbo l will a lso go out if the speed
exceeds the
stored maximum s peed by more than about 2 5 mph ( 40 km/h) fo r at
least 10 seconds . The stored maximum speed is deleted.
Speed warning 2
Storing warn ing 2 is recommended if you always want to be reminded
of a ce rta in speed, fo r example when yo u are traveling in a country
that has a general maxim um speed limit, or if you do not want to
exceed a specified speed for win ter tires .
The speed warn ing 2 symbol,
8. ( U SA models)/ 8. (Canada models)
appea rs in the d isp lay w hen you exceed the store d speed limi t. U nlike
warning 1, it will not go o ut until the vehicle speed drops be low the
sto red speed limi t.

[I] Tips
Even thoug h your vehicle is eq uipped with a speed warning system,
you should st ill watch the speedometer to make sure you are not

Tie-downs
The luggage compartment is equippe d with four tie­
d o w ns to secu re lu ggage and other i tems.
Use the t ie-downs to sec ure yo ur ca rgo prope rly=> page 177 ,
"Load ing the luggage compartment" .
In a c oll ision, t he laws of physics mean that eve n small er item s tha t
are loose in the vehicle will become heavy missiles that can cause
s er iou s injury. Ite ms i n t he vehi cle p osses s ene rgy w hich vary w it h
vehicle speed and the weight of the item. Vehicle speed is th e most
sig nifi ca nt fa ctor.
For examp le, in a frontal collis ion at a speed of 30 mph (4 8 km/h) ,
the forces acting on a 10- lb (4.5 kg) object are a bout 20 times the
normal weig ht o f th e ite m. Th is mea ns that t he weight of t he ite m
wou ld s uddenly be abo ut 200 lbs. (90 kg) . You can imagine the inju­
r ies tha t a 200 lbs . (9 0 kg) item fly ing freely throug h the pa ssenge r
compartment could cause in a collision like this.
& 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 inju ry.
• Always use suitable mounting straps and properly secure items
to the tie-downs in the luggage compartment to help prevent
items from shifting or flying forward as dangerous missiles.

& WARNING
(co ntinued )
• When the rear seat backrest is folded down, always u se suit­
able mounting straps and properly secure items to the tie-downs
in the luggage compartment to help p revent items from flying

Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors~
page 241. If a not iceab le
slip is detected at the wheels (e.g . on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
& WARNING
• When ac ce le rating on s lippery surfa ce s, su ch as on ic e or snow,
alwa ys be ca reful when depre ssing the accele rator pedal. Even
& W ARNING (continue d)
with the EDL working , the dri ve wheels c an spin and reduce your
ability to contr ol your car . Ri sk of cra sh!
• The inc reased s afety afforded by E DL does not me an that you
can take safety ri sks. Alwa ys adapt your d rivin g style to the r oad
conditions and t raffic situation .
[ i ] Tips
If a fau lt occurs in the ABS, the EDL is also not funct ion ing. This is
ind ic a ted by the ABS warn ing light ~
page 17. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Sl ip Regu lation System (ASR) is integrated in the electronic
stabiliza tion prog ram ( ESP) . When the ve hicle s tarts up and acceler­
ates, the wheels are prevented from sp inning by adjusting the engine
powe r to match the amount of g rip available from the road surface .
How the system works
ASR performs au toma tic a lly, i.e. witho ut the dr ive r's intervent ion.
With the aid of the ABS sensors~
page 241, ASR monitors the speed
of the driven wheels. If the whee ls start to spi n, eng ine torq ue is
reduced automatically unti l the tires find enough grip to lock onto
t he road s urface . The system is active across the en tire spee d range.
Th e ASR works in con ju nction with the ABS .
If a malfunction shou ld
occur in the ABS, the ASR wi ll also be out of action.
Act ivating
T he ESP is automatica lly activated when the engine is started and it
performs a self-test . You can act ivate a deact ivated ASR if required by _,,

Intelligent technology
--------------------------------------------------' '----'----
pressing the=> page 236, fig. 198 button. When it is activated, the
message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if req uired by press ing the button (for less
than 3 seconds) =>
page 236, fig. 198. With the ASR deactivated, the
ESP check light comes on, see=>
page 15. The message ASR off
appears in the display as well. The ASR can be deactivated at any
speed.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make sense
to deactivate the ASR. Examp les:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .
When the abnormal situation is over, you sho uld activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tir es . Any differences in rolling radius of the tir es can
cause the system to reduce eng ine power when this is not desired .

Braking
General information
What
affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending la rgely on ope rating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte ­
nance booklet.
Failure to have your b rake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking effect of the engine. This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when b rak ing depending on the speed, braking
force and outside cond itions such as temperatu re and humid ity.
Moisture or road salt
If you are driving faster than 31 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regula r interva ls so as to improve reaction time when braking on wet
surfaces. You, the driver, will not not ice anything.
Under certain condit ions, for example, when driving through water or
very heavy rai n, or even after washing your vehicle, the braking effect
can be reduced due to moisture (o r in free zing conditions ice) on the
bra ke pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
Th e effectiveness of the brakes can be reduced when the vehicle is
dr iven on a salt-covered road and the brakes are not used. H ere too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=>&,.

Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed .
Power steering will not work if the engine is off . As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing) , - more effor t will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set r ight by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the rig ht or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
farthest to the rear on the left s ide of the eng ine compartme nt
=>
page 2 76 . T he correct fluid leve l in the reservo ir is im port an t fo r
proper functioning of the power steeri ng .•
Dr"ving with your quattro®
With all wheel drive, all four wheels ore driven.
General information
With all wheel d rive, power is d istributed to all four wheels. This
h appens a utomatically depending on your dr iv ing style and t he road
conditions at the time . See also =>
page 238, "Electronic different ial
loc k (ED L)".
T he all whee l dr ive concept is designed for high engine power . Your
veh icle is except ionally powe rf ul and has excellent driving character­
istics both under normal driving condit ions and on snow and ice .
Always read an d fo llow safety precautions =>& .
Winter tires
When driving in the winter, your vehicle with a ll whee l drive has an
adva ntage, even w ith regular t ires . In winter road cond it io ns it may
be advisable to mount winte r tires (or all-seaso n tires) for improved
dr iveability a nd b rak ing: t hese tires mus t be mounted on
all four
wheels . See also => page 307, "Winter ti res" .
Tire chains
Where tire chains are mandatory on certa in roa ds, this norma lly a lso
applies to veh icles with a ll w heel drive =>
page 308, "Snow chains" . Iii-

Intelligent technology
--------------------------------------------------' "---.L==--
Repl acing wheel s/tires
Vehicles wi th all wheel drive must a lways have tires of t he same size.
Also avoid tires with different tread depths. For details see page
=> page 303, "New tires and rep lacing tires and wheels".
Off -Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road veh icle . It is therefore best to avo id ro ugh tracks and uneven
terrain as m uch as possible . Also refer to=>
page 247.
& WARNING
Alway s adju st your driving to road and traffi c conditi ons. Do not
let the ex tra safety afforded by all wheel dr ive tempt you into
taking extra risks.
• Although the all wheel dri ve is ve ry effecti ve, always
remember that braking capacity is limited by tire traction. You
should therefore not dri ve at ex cessive speeds on icy or slippery
road surfaces .
• On wet road surfaces , be careful not to drive too fast because
the front wheel s could begin to slide on top of the water (aqua­
planing ). If th is should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle. Always drive at speeds which are suited to the road cond i­
tions -ris k of crash.
