-When switching the ignition on, the needles
in the instrument cluster swing upward
briefly.
- The illumination for the instrument cluster
lights up whenever you switch on the igni­
tion with the
vehicle headlights off. As the
daylight fades, the instrument cluster illu­
mination likewise dims automatically and
will go out completely when the outside
light is very low . This feature is meant to re­
mind you to switch on the headlights when
outside light conditions become poor.

Engine coolant temperature gauge
The engine coolant gauge¢ page 10, fig. 3@
only works when the ignition is on. To prevent
damage to your engine, please note the follow­ ing important points:
Engine cold
If the needle is at or close to the bottom of the
gauge, the engine has not yet reached its operat­
ing temperature. Avoid high engine speeds,
heavy engine loads, and heavy throttle applica­
tions .
Normal temperature
When the engine has reached its operating tem ­
perature, the needle will move to the middle of
the gauge and remain there. If the engine is
working hard at high outside temperatures, the
needle may move higher on the gauge . This is not
a cause for concern as long as the . warning
li ght i n the inst rument cluster display does not il­
luminate . If the . warning light in the instru­
ment cluster display flashes, this can mean one
of two things : either the coolant
temperature is
too high, or the coolant
level is too low

A WARNING
-Always observe the warning in ¢ page 203,
before opening t he hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the engine cool off
firstsothatyoucannothearo rseeany
steam or engine coo lant.
0 Note
- Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atu res or high engine load, the engine could
overheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the vehi­
cle is moving. If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
ized Audi dealer for assistance.
Tachometer (engine rev counter )
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops below 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum permis­
sible eng ine RPM after the break-in period. Be­
fore reaching this area, move the selector lever
to position D/5 or ease your foot off the accelera­
tor pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should only briefly be in the red zone: you
could damage your eng ine! The beginning of
the red zone varies depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Switching on time, date, temperature
display and odometer
The display appears for approximately 30 sec­
onds when you press the

with the ignition off.
Starting the Auto-Check sequence
The Auto-Check system constantly monitors cer­
tain indiv idual functions and components of the
vehicle when the ignition is turned on and when
the vehicle is moving.
With the ignition turned on, you can start the
"Auto-Check sequence" by pressing the
! SETI but­

when the vehicle is stat ionary and the ignition is
turned on or when the vehicle is moving slower
than 3 mph (5 km/h).
In addition, the number of keys initialised for
your vehicle is displayed.
L2 3/3 means that
th ree keys have been initialised. This feature e na­
bles used car buye rs to make su re they have re­
ceived all of the keys.
If you are given only two keys, for instance, you
should take the veh icle and the existing keys to
an authorized Audi dealer to have the missing key
disabled. It is also important to notify your insur­
ance company about the loss.
Setting the speed warning
By pressing the ISETI button briefly, you can set

and be damaged.

9:::1: Engine oil pressure
The red engine oil pressure warning symbol re­
quires immediate service or repair . Driving with a
low-oil-pressure indication is likely to inflict se ­
vere damage to the engine.
• Turn off engine! Oil pressure too low
If the indicator lig ht t urns on and the message
appears, the oi l pressu re is too low.
~ P ull off the road.
~ Stop t he vehicle .
~ Turnoff the engine.
~ Check the engine oil level¢ page 207 .
~ If the engine oil leve l is too low, add engine oi l
¢

display before you s ta rt driving ag ain.
~ If the engi ne oil leve l is cor rect and t he i ndic a­
tor lig ht still tur ns on, turn t he eng ine
off and
do not continue driving . Seek p ro fessional as ­
s istance .
(D Tips
- The engine oil pressure symbol. is not
an indicator for a low engine oil level. Do
not rely on it. Instead, check the oil level in
your engine at regular intervals, preferably each time you refuel, and always before
going on a long trip.
- The yellow oil level warning indication
Ill
requires oil refill or workshop service with ­
out delay . Do not wait until the red oil
pressure warning. starts to flash before
you respond to the low oil level warning
Ill . By then , your engine may already have
suffered serious damage .

Driver information system
Trip computer
Introduction
Applies to vehicles: with trip computer
The trip computer gives you information on cur­
rent and average fuel mileage, average speed ,
fuel range and driving tim e.
F ig. 9 Tri p computer display: Average fuel mileage
~ 9 a: co a,
The fo llow ing information is cont in uously evalu ­
ated by the trip comp uter and can be displayed
sequent ia lly in the instrument cl uster display:
Fuel range
T he est ima ted c ruising range in miles ( km) ap­
pears in the d isp lay. Thi s tells you how far your
veh icle w ill be able to t ravel o n the cu rrent tank
of fuel and with the same driv ing style . The dis­
p lay changes in increments of 5 miles (10 km).
T he cruising r ange is calc ulated based on the fuel
consumption for the last 18 m iles (30 km). If you
drive conse rvatively, the cruis ing range will in­
crease.
Average fuel mileage
T he aver age f uel economy in MPG (l/ 100 km)
since you last cleared the memo ry appears in this
disp lay . You ca n use this display to a djust your
d riving technique to achieve a desired mi leage .
Current fuel mileage
T he inst antaneo us f ue l cons umption in miles per
g all on ( l/ 10 0 km) i s show n in th is display . Yo u
can use t his disp lay to ad just yo ur driv ing tech ni­
que to ach ieve a desi red mileage .
Fue l cons umption is re cal culat ed a t inte rv a ls of
33 y ards (30 meters). T his d isp lay sw itches to
24
gallons/hour (liters/ho ur) when the vehicle is not
moving .
Average speed
The average s peed in mp h (km/h) s in ce you last
re se t t he memory ap pears in t he di sp lay.
Elapsed time
The length of time that yo u have been drivi ng
s ince you last reset the me mory a ppears in this
display .
Distance
The distance th at has been covered since the last
time the memory was cleared appears in the dis­
play .
(D Tips
- Fu el consumptions (ave rage and cur rent),
range and speed are d isp layed in metric
units on Canadian mod els.
- All stored values will be lost if the vehicle
battery is disconnected.
Memories
Applies to vehicles: with trip computer
The trip computer is equipped with two fully au ­
tomatic memories as well as an efficiency pro­
gram* .

data from the tota l-trip memory is being dis­
p layed (memory level 2). The fuel pump nozzle
ii indicates the efficiency program*
¢page 26.
Single-trip memory (Trip computer 1)
The single-trip memory stores the trip informa­
tion 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 w ill be included in the calculat ion of
the current tr ip inf ormat ion . If the trip is inter ­
rupted fo r
more than 2 hours the memory is re­
set automat ica lly.
Total-trip memory (Trip computer 2)
Unlike the single-trip memory, the total-trip
memory is not reset automatically. This permits
you to evaluate your driving data for the entire period between manual resets.
Efficiency program*
The efficiency program can help you to use less
fuel¢
page 26.
Operation
App lies to vehicles: with trip computer
The trip computer is controlled by two switches
on the windshield wiper lever.

gram*), information about other systems can a l­
so be shown in the display. To sw itch the display
between the different information, tap the
I RESET I button @ briefly.
Resetting values to zero
• Select a value in the desired trip computer or in
the efficiency program *.
• Press and hold the
