30 Instruments and warning/indicator lights
Display brightness
You can adjust the display brightness in the
MMI. The display brightness decreases auto ­
matica lly as the amo unt of light decreases.
The basic leve l of brightness is adjusted with
the instrument illumination

(D Note
To prevent scratches on the glass covering
the Head-up Disp lay, do not place any ob­
jects in the projection opening.
@ Tips
- Sunglasses with polarization fi lters and
unfavorable lighting conditions can af­
fect the display.
- A specia l windshield is needed for the
Head-up Display function.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II! 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 o ut 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
ing, a ma lfunction may exist in the engine 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 condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed
limiter may also be malfunctioning. For more information

limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 16 Locat ion of Data L ink Con nector (DLC)
On-Board D iagnost ics monitors the compo­
nents of your em iss ion 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.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illum inates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed
c:> page 218.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe ­
cial 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 located to the
right of the hood release
r=.> fig . 16 .
Your authorized Audi dea ler or a qualified
serv ice station can interpret the code and per­
form the necessary repair.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause

218 Fuel supply and filling your fuel tank
container meets industry standards (ANSI/
ASTM F852 -86) .
(D Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalytic converter.
Refuelling

fl ap
Fig. 180 Fu el f iller flap with attached f uel cap
When activating the central locking, the fuel
filler flap is automatically unlocked or locked .
Refuel the vehicle with the ign ition switched
off .
Taking the fuel cap off
,. Press the left side of the fuel filler flap to
open it
c:> fig. 179 -arrow -.
,. Unscrew fuel filler cap counter -clockwise
and hang it on the fuel filler flap
c:> fig. 180.
,. Check the label on the inside of the fuel fill­
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Refuelling procedure
,. Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go .
,. Select a med ium r efuelling rate so that the
no zzle switches off automatically when the
tank is full.
Putting the fuel cap back on
,. After filling your tank, twist the fuel filler
cap clockwise as far as it w ill go.
,. Close the fue l filler flap.
T o avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp
c:> page 30
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fue ling. The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your veh icle when refu-
eling or filling a portable fuel conta iner . ..,

-For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, full or empty may leak and could cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container while it is anywhere in or on the vehicle
(for examp le, in the luggage compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­ n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle comp lete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container . This will
he lp prevent static electricity from dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are highly f lammable.
- Always observe local and state/provin­ cial laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets industry standards (ANSI/ ASTM
F852-86).
«I) Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches
off automatically for the first
time, the tank is full . Do not try to add
more fue l because fuel may spill out. In
add ition, the expans ion space in the fuel
tank will be fi lled -causing the fue l to
Fu el su ppl y and fi lling yo ur fu el t an k 219
overflow when it becomes warm and pol­
l ute the environment .
(0 Tips
-Running your eng ine while refue lling
may cause vapors to escape or even
cause fuel to spill out of the tank . This
would then shut
off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
- Diesel vehicles* are equipped with a die­
sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au­
thorized repair facility for assistance.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside . •
