If you disconnect the battery terminals, no calculations can be
made for the service interval display during this time and no service
reminder will appear. Remember that observing the proper service
intervals is vitally important to extending the life of your vehicle,
particularly the engine , and maintaining its value. Even if the

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU -in the instrument cluster
=> page 17, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The 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
while you are driving , a malfunction may exist in the engine system .
If the light starts flashing, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) 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 =>
page 30, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 293. •

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

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 vehicle. To reduce the risk of sudden tire
failure 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 vehic le from going faster than the
tire speed rating . For more information=>
page 325.
If the vehicle approaches the tire speed rating, the engine control
unit wi ll turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed .
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Lamp (MIU 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, traffi c and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires
installed .•

Driver informati on displ ay
Trip computer
Introduction
The trip computer gives you informati on on current and
average fuel mileage, average speed, fuel range and
driving time.
F ig. 22 T rip compu te r
di spl ay: Ave ra ge f uel
mil eage
The fol lowing driving information is continuously evaluated by the
t rip computer and can be displayed sequential ly in the instrument
cluster display.
Fuel r ang e
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to trave l on the
current tank of fuel and with the same driving sty le. The display
changes in increments of 6 miles (10 km).
The cruising range is ca lculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Avera ge fu el mil eage
The average fuel economy in MPG (1/100 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.
C urr en t fu el mi leage
The instantaneous fuel consumption in m iles per gallon (1/ 100 km)
is shown in this disp lay. You can use this display to adjust your
driving technique to achieve a desired mileage .
Fuel consumption is recalculated at interva ls of 33 yards (30
meters) . When the vehicle is stationary, the most recent fuel
consumption is displayed .
Averag e sp eed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
E la psed time
The length of time that you have been driving since you last reset
the memory appears in this display.
[ i ] Tips
• Fuel consumptions (average and current), range and speed are
displayed in metric units on Canadian models .

Single-trip memory (Trip computer 1)
The single-trip memory stores the trip information from the time the
ignition is turned on until 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)

automatically . This permits you to evaluate your driving data for the
entire period between manual resets .•
