On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in
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 work ing proper
l y.
Driver information display 29
If the light does not go out after the engine
is started, or illuminates while you are driv
ing , a malfunction may exist in the engine sys
tem.
If the light illuminates, the catalytic con
verter could be damaged.
Continue d rivin g
with reduced power (avoid
ing su sta ined high speeds and/or rapid accel
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
li miter may also be malfunct ioning. For more
information

On-Board Diagnostics
Fig. 18 Location of Data Link Connector (D LC)
On-Board Diagnostics monitors the compo
nents of your emission contro l 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 memo ry .
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys
tem. If the light illumi nates afte r a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed

A WARNING
-New brake pads don't have the best stop
ping power and must be "b roken -in" dur
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity dr iving .
You can compensate for this by pressing the brake pedal more firmly. This also
applies la ter when new pads are instal
led.
- You should per form braking m aneuvers
for the purpose of cleaning the brake
system only if road conditions permit .
Other road users must not be p ut at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gea r or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often . Th is could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance .
- Unde r ce rtain climatic and ope rat ing
conditions such as passing thro ugh wa
ter, dr iv ing in heavy rain o r after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,

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 207,
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 216, ~ 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 216.
-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 starting 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
fu el
con sumpt ion .
Check you r oil ea ch time you fill you r ta nk.
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.
This also app lies to fue l consumption and en
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance 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, ignition 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 mi les
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

the car wash operator to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your
self from sharp meta l components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef
fect may be delayed due to moisture on
the brake rotors or ice in the winter . The
brakes must be dried first with a few
careful brake applicat ions .
{[) Note
-If you wash the vehicle in an automatic
car wash, you must fold the exterior m ir
rors in to reduce the r isk of damage to
the mirrors . Power folding exterior m ir
ro rs* must only be folded in and out us
i ng the power folding function.
- To prevent pa int damage, do not wash
the veh icle in direct sunl ight. -
To reduce the r isk 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.
