On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢4' i n
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized .
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates while you are driv­
i ng, a malfunction may exist in the eng ine sys­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light il luminates, the electronic speed
limiter may also be malfunct ioning. For more
information
c:> page 31 , Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate
c:>page 212.
On-Board Diagnostics
Fig . 18 Locat io n of Data Link Con nector (D LC)
On-Board Diagnostics monitors the compo ­
nents of your emission control system . Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, 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 fuel vapor recovery sys­
tem. If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
c:> page 212 .
In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe­
c ial diagnostic equipment (generic scan tool
furOBD) .

after a short time. Repeat starting proced ure .
A WARNING
-Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never remove the ign ition key from the
ignition look while the vehicle is moving.
Otherw ise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle.
- Always take the key with you whenever
you leave your vehicle . Otherwise, the
engine could be started or e lectr ical
equipment such as the power w indows
cou ld be operated. This ca n lead to seri­
o us inj ury.
- Never leave ch ild ren or persons requiring
assistance unattended in the veh icle. The
doors can be loc ked using the remote
transmitter, preventing people from es­ caping from the vehicle on their own in
the event of an emergency. Depend ing
on the time of year, people inside the ve-
On th e ro ad 81
hicle can be exposed to very high or very
low temperatures.
(D Note
Avoid high eng ine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating tempe rat ure -other­
wise you r isk eng ine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin dr iv ing immediately. This
reduces unnecessary emissions.
@ Tips
- If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehi-
cle <=:>

-After starting a cold engine, there may
be a brief period of increased no ise be­
cause the oil pressure must first bu ild up
in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If you leave the veh icle with the ignition
switched on, the ign it ion w ill switch off
afte r a certa in per iod of t ime . Please
note that ele ctrical equ ipment such as
exterior ligh ts w ill sw itch off as well
when that happens .

CD Note
If the engine has been under heavy load
for an extended period, heat builds up in
the engine compartment after the engine
is switched off- there is a risk of damaging
the engine . Allow the engine to run at idle
for about two minutes before switching it
off.

If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure .
When starting the engine , major electrical
loads are switched off temporari ly.
After a cold engine is started, there may be a
brief period of inc reased noise because oil
pressure must first build up in the hydraulic
valve adjusters. This is normal and not a cause
for concern.
A WARNING
- Never allow the engine to run in confined
spaces - danger of asphyxiation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- Always take the key with you whenever
you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated . This can lead to seri­
ous injury .
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es­
caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve­
hicle can be exposed to very high or very
low temperatures .
CD Note
-Avo id high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature - other­
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
(D Tips
-After starting a cold engine, there may
be a brief period of increased noise be-
cause the oil pressure must first bui ld up
II-

th e brakes or hold the pedal down too
long or too ofte n. This cou ld cause the
brakes t o get hot and dimi nish b raking
efficiency .
- Do not "r ide t he b rakes" by resting your
foot on the pedal when you do n ot intend
t o brake . Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certa in climat ic and operating
condit ions such as passing through wa­
ter, driving i n heavy rai n or after wash ing
the vehicle, the effe ct iveness of the
brakes can be re duced. In winter, ice can
acc umulate on the brake pads, linings,
discs and drums. Carefully apply brakes
f or a test. Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake app lications.
- Driv ing for an extended period of time on
salt-covered roads w ithout using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat io ns.
- If you damage the front spo iler, or if you
install a diff ere nt spoiler, be sure the air
flow to t he front b ra kes is not obstr uct­
ed . Otherwise the br ake sys tem co uld
overheat red ucing the effectiveness of
the ent ire brake sys tem.
- F ailure of one br ake circui t will im pair
the brakin g capability res ulting in an in­
creased stop ping distance . Avoid driving
the vehicle and have it towed to t he near­
est author ized Audi dealer or qualified
workshop.
- Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not work ing, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.

8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it .
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water .
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic conv ert er) is function ­
ing properly to ensure that your vehicle is run­
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 209,
Fuel supply .
,,. Never run the tank down a ll th e way to emp ­
ty.
,,. Never put too much moto r oil in your engine
Q page 219, "t':::r. Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean­
up" device built in to the exhaust system of
the vehicle . The catalytic converter burns
many of the polluta nts in the exhaust gas be ­
fore they are released into the atmosphe re . The exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert­
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop­
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
CI) Note
- Be aware tha t just o ne tank filling with
leaded fu el w ill alre ady ser io usly de ­
grade the performance of the cata lytic
converter .
- Do not exceed the cor rect engine oil level
Q poge 219.
-Do not drive until the fuel t ank becomes
comple tely empty . The engine cou ld mis ­
fire . Unburned fuel could also get into
the exhaust system and th is co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
co uld result in overheating of the con­
verter, requir ing its replacement.

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic lights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned s tarti ng the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumpt ion .
Check you r oil ea ch time you fill you r tank.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
-Do not alter or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid dr iv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis­
s ions effectively .
Just after starting, a co ld eng ine in a mid-s ize
car only achieves a fuel economy of 6-8 m iles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>

A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk of accidents .
- To reduce the r isk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
t he wheel housings.
- After washing the vehicle, the braking ef­
fec t may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
Q) Note
- If you wash t he vehicle in an automatic
car wash, yo u must fold the exterior m ir­
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior mir­
rors* must only be folded in and out us­
ing the power folding function.
- To prevent paint damage, do not wash
the vehicle in direct sunlight . -
To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fi nish paint. The paint cou ld be
damaged when the stickers o r magnets
are removed.
@ For the sake of the environment
Only wash the vehi cle in facilities spec ial ly
designed for that purpose . This will red uce
the risk of dirty water contam inated with
oil from entering the sewer system.
