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

Vehicle care Do-it-yourselt service iTechnical data

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 .

Single-trip memory (Trip computer 1)
The sing le-trip memory stores the trip information from the t ime the
ignition is turned on until it is turned off. If the trip is continued
within 2 hours from the time the ignit ion was turned off, the new
data will be included in the calculation of the current trip informa-

entire pe riod between manual resets. •
Operation
The trip computer is controlled by two switches on the
windshield wiper lever.

This will cause the five distinct trip computer functions to
be displayed one after another.
The trip computer will not operate unless the ignition is on. When you
turn on the ignition, the function that was in use when yo u last tu rned
the ignition off will be d isplayed.
In addition to information on the on-board computer (on-board

desired function and press the Reset button @ for at least one
second. The following values can be set to zero
individually using the
Reset button:
• Average fuel mileage
• Average speed
• Elapsed time
• Distance
In addition,
all the values in the single-trip or the total-trip memory
can be deleted simultaneously=>

[ i ] Tips
All stored values will be lost if the vehicle battery is disconnected. •
Basic Settings for the trip computer
The MMI* or the radio operating unit is used for setting
the trip computer's basic settings .
-Select: Function button [CARI> Instrument cluster > On-

or On-board computer 2.
Th e values in the single-trip or the total-trip memory can all be reset
to zero at the same time under
Reset in the menu.
In addition, you can determine what information from the trip
computer should be shown in the instrument cluster display. If one
of the pieces of driver information is turned
off , that driver informa­
