Trip computer
Introduction
The trip computer gives you inf ormation on current and
average fuel mileage, average speed, fuel range and
driving time .

mi lea ge
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ ~ page 40 , fig. 27
You can tell which memory level is currently active by the number in
the display ~ fig . 26 . The data from the single -trip memory
(memory level 1) is being disp layed if a
1 appears in the display. If a
2 is shown, then the data from the total -trip memory is being
displayed (memory leve l 2) .
Sin gle -trip mem ory (Trip compute r 1)
The single -t r ip 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 hour s from the time the ignition was turned off, the new
data wi ll be included in the calcu lation of the current trip informa ­
tion. If the trip is interrup ted for
more than 2 hour s the memory is
reset automatica lly. _,.

To ta l-tr ip mem ory ( Trip compu te r 2)
Unlike the single -trip memory, the total -tr ip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manua l resets.
Fu el r an ge
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 sty le . The display
changes in increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
t he last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Average fuel m ile ag e
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 ur rent fuel mil eage
The instantaneous fuel consumption in mi les per gallon (1/100 km)
is shown in th is d isplay. You can use this display to adjust your
driving technique to achieve a desired mileage.
Fue l consumption is recalcu la ted at intervals of 33 yards (30
meters). When the vehicle is stationary, the most recent fuel
consumption is d isplayed .
Average speed
The average speed in mph (km/h) s ince the last time the display was
reset appears in the display .
Elap se d time
The length of time that you have been driving since you last reset
the memory appears in this display.
Di stance
The elapsed distance since the last time the memory was cleared
appears in the display. The maximum distance that can be recorded
is 9,999 .9 miles (9,999 .9 kilometers).
[ i ] Tips
• Fuel consumptions (average and current), range and speed are
displayed in metric units on Canadian models.
• All stored values will be lost if the vehicle battery is
disconnected .•
Operation
The trip computer is controlled by two switches on the
windshield wiper lever.

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significant ly
under -inflated. The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
Accordingly, when the low tire pressure tellta le illuminates, you
should stop and check your tires as soon as possib le, and inflate
them to the proper pressure. Driving on a significantly under­
inflated t ire causes the tire to overheat and can lead to tire failure .
Under -inflation a lso reduces fuel efficiency and tire tread l ife, and
may affect the vehicle's handling and stopping ability.
(D Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's respons ib ility to maintain correct
tire pressure, even if under -inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale .
• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflat ion pressure recommended by the
vehic le manufacturer on the vehicle p lacard or tire inflation pres ­
s u re label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure labe l, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure _.,

PANIC B utton
- Push the red button@to activate the panic function. The
horn sounds and the turn signals flash.
- Push the button ® again to deactivate the panic func-
tion.

open or close the driver's door.
The transmitter and battery are located in the head of the remote control. The receiver is located inside the vehicle. The maximum
effective range depends on several things. Remember, if the battery
is weak, the effective range decreases.
The remote -contro l key contains a fo ld -out key that you can use to
manually lock or unlock the vehicle and to start the engine.
If you need to replace the remote contro l, or if you need to have it
repaired, you must see your authorized Audi dealer . On ly then can
you use the key again.
& WARNING
Re ad and follo w all WARNINGS ~ & in "General de scr iption " on
page 50 .
[ i J Tips
• The remote control key is automatically deactivated when the
ignition is switched on.
• The operation of the remote control key can be temporarily
disrupted by interference from transmitters in the vicinity of the vehic
le working in the same frequency range (e.g . a cell phone,
radio equipment).
• In order to make sure the locking function is working, you should
a lways keep your eye on the vehic le to make sure it is properly
locked .
• Do not use the remote control if you are inside the ca r, otherwise
you may unintentionally lock the vehicle, and then you would set off
the an ti-theft alarm when you try to start the engine or open a door.
I n case this happens anyhow, push the unlock button@.
• Use the panic func tion only if you are in an emergency
situation. •
Resetting the remote control

The various electrical circuits are protected by fuses . The fuses are
clustered in a central ized unit. The unit is located behind the face
panel at the end of the instrument panel.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are wel l advised to keep a supply of spare fuses in your vehicle .
Fuses with the proper ampere ratings are availab le at your autho­
rized Audi dealer .
& WARNING
Never replace a fuse with one that has a higher amperage rating .
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
0 Note
• On no account should fuses be repaired (e.g. patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause for the repeated short circuit or overload tracked and
fixed. •
