Warning light in the instrument cluster display-1-
If the _L warning light in the i nstrument clus ter display flashes, this
can mean one of two things: either the coo lant
temperature is too
high, or the coolant
level is too low ~ page 29.
If the needle is well in the uppe r area of the gauge, the coo lant
temperature is too high.
Stop the vehicle, switch the engine off, and
allow it to cool.
If th e war ning light comes o n ag ain af ter driv ing a
short distance, contact an author ized Aud i dea ler or othe r qualified
wor ksh o p.

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. •

display: Average fuel
mi~age
~

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).
This display switch es to gallons/hour (liters/hour) when the vehicle is
not moving .
Average speed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
Elapsed time
Th e length of time that you have been driving since you last reset the
memory appears in this display.
Distance
The d istance that has been covered since the last time the memory
was cleared appears in the display .
