On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunct ion Indicator Lamp (MIL) in the instrument cluster
=>
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e 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 properly.
If the light does not go out after the engine is started, or illuminates
whi le you are driving, a malfunction 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 Aud i dealer .
If the light illuminates, the electronic speed limiter may also be
malfunction ing. For more information=>
page 22, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 2 76. •

Vehicle care Do-it-yourselt service iTechnical data

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 fuel
vapor recovery system. If the light i llumi nates after a refueling , stop
the vehicle and make sure the fuel filler cap is properly closed
=> page 276.
In order to make an accurate diagnosis, the stored data can only be
displayed using special 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
=> page 21, fig. 14.
Your authorized Audi dea ler or qualified workshop can interpret the
code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equipped with 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. To reduce the risk of sudden t ire
fai lure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information=>
page 307.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Ind icator Lamp (M IL) will illuminate. If this
occurs , contact the nearest authorized Audi dealer for assistance .
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires
installed. •

The following information is continuously evaluated by the trip
computer and can be displayed sequentially in the instrument cluster
display:
Fuel range
The estimated cruising range in miles (km) appears in the display .
This tells you how far your vehicle will be able to travel on the current
tank of fuel and with the same driving style . The display changes in
increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km) s ince you last cleared
the memory appears in this disp lay. You can use this display to adjust
your dr iv ing techn ique to ach ieve a desired mileage.
Current fuel mileage
The instantaneous fuel consumption in miles per ga llon {l/100 km) is
shown in this display. You can use this display to adjust your driving
technique to achieve a desired mileage .
Fuel consumption is recalculated at intervals of 33 yards (30 meters).

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver exceeds a previously
stored maximum 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 the display. The symbol 's
appearance might be different in some models .
The speed warning system has
two warning thresholds that function
independently of each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maximum speed while you are
driving. This setting w ill remain in effect until you turn off the igni­
tion, assuming that you have not changed or reset the setting .
The speed warning symbo l
0 (USA models)/0 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed .
It goes out when the speed falls be low the stored maximum speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph
(40 km/h) for at
least
10 seconds. The stored maximum speed is deleted.
Setting speed warning 1
=> page 25.
Speed warning 2
Storing warning 2 is recommended if you always want to be reminded
of a certain speed, for example when you are travel ing in a country
that has a general maximum speed limit, or if you do not want to
exceed a specified speed for winter tires.
The speed warning 2 symbol,
8, (USA models)/ 8, (Canada models)
appears in the display when you exceed the stored speed limit. Unlike

Auto Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle
features and components. It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the veh icle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument cluster display.
You will also hear an audible warning tone. The displays are color
coded in e ither red or yellow depend ing on their level of priority . A
red symbol means
Danger, a yellow symbol indicates Warning . In
certain situations, information message for the driver appear in addi­
tion to the red and yellow symbols.
Th e Auto-Check Contro l will automatically perform a test each time
you switch on the ignition. With the selector lever in
P or N, the
following message appears in the display:
When stationary apply footbrake while selecting gear.
When you a select a different gear (for example: R, D, etc.), the
message will disappear and the Auto-Check function is displayed.
If there is a malf unction, then the malfunction message will appear
about 15 seconds after you start the vehicle. At the same time you
w ill hear a wa rning tone. •
