The illumination for the instrument cluster lights up whenever you
switch on the ign ition with the
ve hicle hea dlight s off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and wil l go out completely when the outside light is
very low. This feature is meant to remind you to switch on th e head ­
lights when outside light conditions become poor. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes) .
The tachometer 0 ~ fig. 2 is the left of the two large c lock -type
displays.
The engine turns at a speed
1,000 times the single digit in the
display, e.g . if th e ne edle is pointing a t the
"2" the engine is turning
at 2,000 RPM .
If engine RPM drops below 1,500, you should downshif t to the next
lower gear . The red ar ea at the end of th e scale indica tes maximum
permissible engine RPM after the break- in period. Before reaching
th is area , shift into the next higher gear (manua l transmission),
move the selec tor lever to position "D (Drive)" (automatic) or ease
your foot off the accelerator pedal.
0 Note
T he tachometer need le should not move into the red range . If it
does, then on ly for a very short period of time . You could damage
your engine by driving a t high RPM. ...

<£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise. •

Engine coolant temperature gauge
The engine coolant gauge~ page 12, fig. 2 © only works when the
ignition is on. To preven t damage to your engine, please note the
following important points:
Engine cold
As long as the needle remains at the left end of the gauge, the
engine still has not reached its operating temperature . Avoid high
engine speeds, heavy engine loads and heavy throttle.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the middle of the gauge and remain there. If the
engine is working hard at high outside temperatures, the needle
may turn further to the right. This is no cause for concern as long as
the -~- warning light in the instrument cluster does not illuminate.
When the
_J _ warning light starts to flash, this can mean one of two
things: either the coolant
temperature is too high , or the coolant
level is too low~ page 32 . ~

c ould burn your self. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting additiona l lights or accessories in front of the a ir inlets
reduces the co oling effect of the radiat or. At high outside tempera ­
tures or h igh engi ne load, the eng ine could overheat.
• The fron t spoile r has been designed t o properly dis trib ute the
coo ling air when the veh icle is mov ing . If the spo iler is damaged,
this could red uce the coo ling effect and the engine co uld then ove r­
heat. Ask your authorized Audi deale r for assistance. •

Driver inf ormation sy ste m
Driver information system
Introduction
General notes
The driver information display inside the instrument
cluster provides you, the driver, with important informa­
tion.
F ig. 7 In st rum ent
c luster : center d is p lay
The driver information display is located in the center of the instru­
ment cluster => fig . 7 .
The driver information system updates important information in the center display in clear view of the driver. In an easy to understand
format, the display tells you how your vehicle is functioning
at t he
cu rre nt m omen t.
For example, the display can tell you how many
miles (kilometers) you can still drive until it is time to bring your
vehicle to your authorized Audi dealer for a scheduled Maintenance Service . This feature helps preventing costly repairs. It is just one of
many different items of information availab le for recall. The display
a lso gives you a "status report" whenever the
so und s ystem , tel e­
ph on e, a nd navi gation
systems are being used.
Detailed instructions for operating the Audi Navigation System* are provided in separate manuals . The Driver Information System provides the following functions:
Sound system display
Outside air temperature
Door open indicator
Service interval display
Auto Check system
Speed limiter
Selector lever (S t ronic)

Service interval display
The service interval display detects when which service category is
required for your vehicle. It works in two stages:
• Service Reminder : Starting with a certain mileage before a
service event, this message appears when the ignition is switched
on:
SERVICE IN 5500 Ml 150 DAYS.
• Service Event:
If the due date for servicing has passed, the
message
SERVICE EXCEEDED! appears This message is accompa ­
nied by a warning signal. And the type of service needed is
displayed.
Checking the Remaining Distance
By briefly pulling the knob,=> fig. 13 -Arrow -, the remaining
distance and time to the next service schedule is displayed with the
ignition on . The distance remaining is updated every 300 miles (500

km). The next scheduled oil change and thereafter the next sched­
uled service will be displayed.
For new vehicles or after the vehicle has been serviced, the next
scheduled service will only be displayed after 300 miles (500 km)
have elapsed. Until this distance has been travelled, the display will
show
OIL CHANGE IN----- Ml ---DAYS and SERVICE IN----- Ml --­
DAYS.
To reset the display
The dealership performing the service resets the display when the service has been completed . You can reset the display in the instru ­
ment panel only if an oil change has been done. Proceed as follows:
• Switch the ignition on .

seconds, the display reset mode closes.
[ i] Tips
• Do not reset the display between service intervals. Doing so will
result in an incorrect display.
• If service was not performed at the correct time or the service
interval display was not reset after service was performed, the addi ­
tional mileage driven or the elapsed days will be shown as negative
numbers.
• If the battery is disconnected, the Service Interval Display values
are retained.
• If a priority 1 malfunction is present (red symbol), the distance
remaining cannot be called up. •

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL )
The Malfunction Indicator Lamp (MIU in the instrument cluster
=:> page 16, fig. 6 is part of the On -Board Diagnos tic (OBD II) system.
The warning/indicator ligh t ill uminates 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 th e light d oes not go out after the engine is started, or illuminates
while you are driving, a ma lfunction may exist in the engine system.
If the light starts flashing, the catalytic converter cou ld be damaged .
Continue driving
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid acce lerations) and have the condition
corrected. Contact your authorized Audi dealer.
If the light illuminates, the e lectronic speed limiter may also be
malfunctioning. For more information=:>

On-Board Diagnostics
F ig . 14 L ocation of
Data Link Co nnector
( DL Cl
On -Board Diagnostics monitors the components of your emission
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
f ue l vapor recovery system. If the light i lluminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
=:>
page 216.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLCl. The DLC is located to the right of
the hood release =:> fig . 14.
Your authorized Audi dealer or a qualified service station can inter ­
pret the code and perform the necessary repair. •
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 in formation=:>
page 249.
If the vehicle approaches the tire speed rating, the engine control
unit will turn off the fue l injectors. You will notice an immediate loss
of engine power and a drop in road speed .
If the engine control unit receives faulty vehicle roadspeed signals,
the Ma lfunction Indicator Light (MIU will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance.
