!7 Engine speed limitation
App lies to vehicles: wi th engine speed l imitatio n
111 Do not exceed max. engine speed of
XX.XX rpm
The eng ine speed is automatically limited to
the speed displayed in the driver information
system. This protects the engine from over ­
heating.

24 Driver information d isplay
Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Trip computer display: Average fuel mileage
The following information is continuously
eva luated by the trip computer and can be dis­
played 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 ve hicle wi ll be able to travel on the cur­
rent tank of fuel and with the same driving
style. The display changes in increments of
5 miles (10 km).
The cruising range is calcu lated based on the
fuel consumption for the last 18 miles
(30 km).
If you drive conservat ively, the cruis­
ing range will increa se.
Average fuel mileage The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this display to adjust
your driving technique to achieve a desired mileage.
Current fuel mileage
The instantaneous fuel consumption in mi les
per gallon (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 recalcu lated at intervals
of 33 yards (30 meters). This disp lay switches
to gallons/hour (liters/hour) when the vehicle is not moving.
Average speed
T he average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that you have been driving
s ince you last reset the memory appears in
th is disp lay.
Distance
The distance that has been covered since the
last t ime the memory was cleared appears in
the display.
(0 Tips
- Fuel consumptions (average and cur­ rent), range and speed are displayed in
metric units on Canadian models.
- All stored values will be lost if the vehi­
cle battery is disconnected .
Memories
The trip computer is equipped with two fully
automatic memories.

Single-trip memory (Trip computer 1)
The single-t rip memory stores the trip infor ­
mat ion from the time the ignition is turned on
unti l it is turned
off. If the trip is continued
within 2 hours from the time the ignition was
turned
off, the new data will be included in
the calculation of the current trip informa­
tion . If the trip is interrupted for
more than 2
hours
the memory is reset automatically .
Total-trip memory (Trip computer 2)
Unlike the sing le-trip memory, the tota l-trip
memory is not reset automatically. Th is per­
mits you to evaluate your driving data for the
entire period between manual resets.
Operation
The trip computer is controlled by two
switches on the windshield wiper lever.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL )
The Malfunction Indicator Lamp (MIL) ¢"4 in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system. T
he warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the id le has stabilized .
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illum inates while you are dr iv­
ing, a malfunction may exist in the engine sys­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Cont inue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dea ler .
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate

On-Board Diagnostics

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 illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
