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.
Th e warn ing/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
Thi s ind icates 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 ma lf u nction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light i lluminates, the electronic speed limiter may also be
malfunctioning. For more information~
page 26, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate (only vehicles with gasoline engine)~
page 290. •
On-Board Diagnostics
Fig . 15 Location of
Data Link Connector
( DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each monito red component in you r engine system
has been ass igned a code. I n case of a malfunct ion, the component
wi ll be ident ified and the fau lt stored as a code in the control module
memory .
The MIL light may also illuminate if there is a leak in the on-board fuel
vapor recove ry system. If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed (only
veh icles with gasoline engine)~
page 290.
I n order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is lo cated to the right of
the hood release ~ fig. 15.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair .•
Electronic speed limiter
Your vehicle may be factory equ ipped w ith tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle. T o reduce the risk of sudden tire
fai lure and loss of contro l if the vehicle is operated at excessive
speeds, your vehicle a lso 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 326.
If the eng ine control unit receives faulty veh icle roadspeed signals,
the Malfunction Indicator Lamp (M IL) ..... will illuminate. If this
occurs, contact the nearest authorized Aud i dealer for ass istance . _.,

& WARNING
Always observe the post ed speed limits and adjust your speed to
s uit prevailing road , traffic and weather condition s. Never drive
your vehi cle faster than the m aximum sp eed rating of the tires
installed .•
Auto Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle
featu res a nd compo nents. It s imp ly makes su re t hese featu res and
components are working properly. The Auto-Check contro l works as
long as the igni tion is on, as we ll as whenever the veh icle is d riven.
If a compone nt is malfunctioning or if the need for an urgent repair
has been detected, this will appea r in the instrument cluster display .
You will also hear an audible warn ing tone . The d isp lays are colo r
coded in e ither red or yellow depend ing on their level of prior ity.
A red symbol means
Danger , a yellow symbol ind ic a tes Warning . In
certain situations, information message for the driver appear in addi­
t ion to the red and ye llow symbo ls.

You can use speed warning 1 to set the maximum speed whi le you are
dr iving. This setting will remain in effect until you turn off the igni­
tion , assuming that you have not changed or reset the setting.
Th e speed warning symbol
'8 (USA models) /8 (Canada models) in
the warning 1 display appears when you exceed the maximum speed .
It goes out when the speed falls below the stored maximum speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 2S mph (40 km/h) for at
least 10 seconds . The stored maximum speed is deleted .

Adaptive Air Suspension
Air suspension and damping
Applies to veh icles : w ith Adap tive Air Suspens ion
Description
Air suspensi on and damping can be regulated as desired
by driver, and they adapt automatically to the driving
situation at the time.
Adaptive Air Suspens ion is an e lectro nically controlled springing and
damping system . This chass is system makes it eas ie r on the d river by
adapting to the particular situation through imperceptible contro l
processes .
The
Adapt ive Air Suspension component regu lates ground clearance
depending on vehi cle speed and driver input .
It fu nc tions in depen ­
dently from the load cond itio n. Accele rating to a speed above a
predetermined limi t will ma ke the vehicle lower itse lf . On the other
hand, driv ing more slowly res ults in the vehicle ra is ing again at
specific s peeds.
T he
damping component provides individua l control of the damping
forces. For example, with damping characterist ics set to provide
greater comfort, damp ing is se t somewh at harder for a br ief period
only as req uired, for example, whe n going aro und a curve or when
bra king.
Settings
Ad aptive Air Suspension provides the drive r wi th the opportu nity to
set the chass is characterist ics also to their individual preference.
With the driving modes
Comfort, Au tomatic an d Dynamic the dr ive r
has three chassis sett ings available, ranging from comfort to spo rty.
Th e
Offroad mode c an be selected for dr iv ing on poor qu ality
st retches of road . In addition,
Li~ provides a f ifth mode, w hich can be
selecte d when exceptionally high ground clearance is needed
:::;, page 177, "C hass is controls" . The modes are set
in MM I:::;,
page 178.
& 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 tires. Never sec ure the vehicle by the ax le, the
suspension struts or the front or rear 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.
• If you are going to tow a trailer w ith a tra iler hitch that was
not
ins talled accor ding t o fac tory spe cifica tion s, you mus t activa te t he

& WARNING
Weak , damaged or improper straps used to secure item s to tie­
downs can fail during hard braking or in a collision and cause
serious personal injury.
• Always use suitable mounting straps and properly secure items
to the tie-downs in the luggage compartment to help prevent

& WA RNING (conti nu ed )
• Plea se be aware th at in ESP offroad mode , particularly on a
s mooth and slippery road, the wheels may have an incr eased
tendency to spin and the vehicle may break awa y -danger of skid ­
ding!
• Stabilit y is limited in the ESP offroad mode. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differe ntia l lock (EDL) helps the ca r to sta rt moving,
acce lerate and climb a gradient on surfaces provi ding poor or almost
no grip. W ithout ED L, th is would be d iff ic ul t, if not impossible .
How the system works
The EDL operates automatically . It mo nitors the rotational speed of
w heels wi th the help of the ABS sensors ==>
page 256 . If a not iceab le
slip is detected at the wheels (e .g . o n slippery g round on one side),
the spin ning whee ls are braked and power is transferred to the other
wheels. This is done up to a speed of about 60 mph ( 100 km/h) .
Noises from the brake system signa l that wheel spin is being
cont rolled.
Driv ing off
W hen d rivi ng off, always be sure to keep road conditions in mind as
you acce lerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of th rottle until t he car starts to move .
Overheating of brakes
To prevent the disc b rake of the bra ked wheel from overhea ting if
subjected to excessive loads on this whee l, t he EDL cuts out tempo ­
ra rily. The vehicle rema ins operat iona l and behaves in the same way
as a veh icle without EDL. As soon as the brake has coo
led down, EDL sw itches on again auto­
m atically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accele rator pedal. Even
with the EDL working , the drive wheels c an spin and reduce your
ability to control your car . Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks . Always adapt your d riv ing style to the road
c ondition s and traffic situation.
[ i ] Tips
If a fa ult occurs in the A BS, the ED L is also no t fu nct io ni ng. This is
ind icated by the ABS warn ing light==>
page 19. •
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tion System preven ts the drive n
w heels from spinning when the car is acc ele rating .
General notes
The Anti-S lip Reg ulation Sys tem (ASR) is in tegr ated in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
a tes, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amoun t of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. witho ut the driver 's intervent ion.
With the aid o f th e ABS sensors ==>
page 256, ASR moni to rs the speed
of the driven wheels. If the whee ls start to spin, engine torque is
reduced automatically unt il the tires find enough grip to lock onto
the road s urface. The system is active ac ross the en tire speed range .
'1>

Intelligent technology
--------------------------------------------------' '----'----
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
& 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 tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when th is 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 large ly on operating 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 brake pads inspected can result
in reduced brake pe rformance .
On steep slopes, you should use the brak ing 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 braking depending on the speed , braking
force and outside conditions such as temperature and humidity.
Safety first
Moisture or road salt
If you are driving faster than 31 mph (SO km/h) and the windshield
wipers are on, the brake pads wi ll briefly touch the brake discs in
regular interva ls so as to improve reaction time when braking on wet
surfaces . You, the driver, will not not ice anything.
Under certain cond itions, for example, when driving through wa ter or
very heavy rain, or even after washing yo ur vehicle , the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
brake pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings .
The effect iveness of the brakes can be reduced when the vehicle is
dr iven on a sa lt-covered road and the brakes are not used. Here too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=> & -
Corrosion
There may be a tendency for dirt to build up o n the brake pads and
corrosion to form on the dis cs if the car is no t driven regularly or only
for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed=> &.
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then one
o f the two brake circuits may have failed==>& .
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored e lectron ically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection =>
page 339,
"Changing a wheel". ._.

Note
If t he re is an elect ro n ic malfunc tion, servotroni c will still funct io n
like a conventional power steering system, provid ing a constant
steer ing suppo rt force tha t is no longer proportiona te to the vehi cle
speed. This is most noticeable when t urning the steer ing wheel at low
speeds (for ex ample when p arki ng) , - m ore effo rt will be req uire d
than usua l.
• Be aw are of the d iffe ren t than usual steeri ng respo nse and adjust
your steering force accord ingly.
• Have t he pr oblem chec ked and set r igh t by a n Audi dea ler as soo n
as possib le .
[I) Tips
• When the engine is runni ng, neve r hold t he steering wheel turned
a ll the way to the r ig ht o r to t he left fo r longe r th an 1 5 seco nd s. The
powe r steering pump will over heat the hydraulic fluid if yo u keep
holding t he s teering w heel turne d all the w ay . This is likely to damage
the power steer ing system.
• If the powe r stee ring sys tem s ho uld fail entire ly, or if the engine
is not running (for examp le, while be ing towed), you will still be able
t o steer the vehicle. Howeve r,
considerably more effo rt will be
required to do so.
• If the powe r stee ring sys tem s ho uld have a leak, or is not func ­
tioning properly, contact your author ized Audi dealer immediately.
• Th e power s teeri ng system re quir es a specially fo rm ulated
hydraulic fluid. The power stee ring reservoir is the one located
f ar the st to the rea r on t he left side of the eng ine compa rtment
=> page 298 . The correct fluid level in the reservo ir is important for
pr op er f unctio ning o f the power steer ing.•

taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive 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- ...

Driving and environment
The first 1,000 miles (1,500 km)
and afterwards
New engine
The engine needs to be run-in during the first 1,000 miles
(1,50 0 km) .
For the first 600 miles (1,000 kilometers):
Do not use fu ll thrott le .
- Do not drive fas ter t han 3/ 4 of the top speed marked on
t h e speedometer.
- Avo id high engine speeds .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
- Spe eds can
gradually be i ncr eas ed to the maxi mu m
perm iss ible road or engin e spee d.
During and after break-in period
- Do not rev the eng ine up to high speeds when it is co ld.
This app lies whether t he tra nsmission is in N ( Neutra l) or
1 n gear.
After the break-in period - Do not exceed maximum engi ne s pee d und er any circum­
stances .
- Up shift i nto t he next hi ghe r g ear

ment Safety first Vehicle operation
During the first few ho
urs of d riving, the engine's interna l fr iction is
highe r than later when all the moving parts have been broken in . How
well th is br eak -in p rocess is done depends to a cons iderab le extent on
the way the veh icle is driven dur ing the f irst 1,000 miles (1,500 kilo­
meters).

E x tremely high e ngine speeds a re au tomat ically re duced. However,
these rpm limits are programmed for an engine well run -in, not a new
engine .
~ For the sake of the environment
Do not drive with u nnecessa rily high engine s peeds -upshift ing early
saves f uel, reduces no ise and protec ts the environme nt.
New tires
If your v eh icl e is run ning on new t ires, driv e p arti cul ar ly
c a refu l fo r the first 35 0 miles (50 0 kilometers) af ter fit ting.
& WARNING
New tires tend to be slippery and must al so be "broken-in ". Be
sure to remember this during the first 350 m iles (500 kilome ­
ter s). Brake gently . Avoid following closely behind other vehicles
or other situations that might require sudden, hard braking. •
