Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel rang e and driving tim e.
Fi g. 15 Trip computer display: Average fuel mileage
The fo llow ing informa tion is cont in uously
eva luate d by the trip compu ter and can be dis
p layed sequent ia lly in the instrument cl uster
d isp lay:
Fuel range
The estim ated cruising r ange in miles (k m)
appears in the display . This te lls you how far
your veh icle w ill be able to t ravel on the cur
rent tank of fue l and with the same dr iving
style. The display changes in increments of 6
m iles (10 km).
Average fuel mileage
The ave rage fue l economy in MPG (l/ 100 km)
since you last clea red the memory appears i n
this display. Yo u can use th is disp lay to adjust
your driving technique to achieve a desired
mileage.
Current fuel mileage
The instantaneo us fue l cons umption in miles
pe r gallo n (l/ 100 km) is shown in this d isp lay .
You can use this display to adj ust your dr iving
techniq ue to ach ieve a des ired mileage.
Fu el consumption is reca lcula ted at interva ls
of 33 yards (30 mete rs) . This display switches
to ga llons/ho ur (lite rs/hou r) when the vehicle
is not mov ing.

Single-t rip memory (Trip computer 1 )
The single-t rip memo ry sto res the trip infor
mat ion from the time the ignition is turned o n
until it is tu rned off . If the trip is contin ued
w ithin 2 hours from the time the ignition was
turned off, the new data will be included in
the calcu lation of the current trip informa
tion. If the trip is interrupted for
more than 2
hour s
the memory is reset automatically.
Total -tr ip m emory (Trip compu ter 2 )
Unlike the sing le-trip memory, the tota l-trip
memory is not reset automatically. This per
mits you to evaluate your driving data for the
entire period between manual resets.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
T he Malfunction Indicator Lamp (MIL) ¢4 in
the instrument cluster
Q page 14, fig. 8 is
part o f the On-Board Diagnostic (OBD II) sys
tem.
T he warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized .
T his indicates that the MIL is working proper
ly .
If the light does not go out after the engine
is started, or illuminates while you are driv
ing, a malfunction may exist in the engine sys
tem. If the light illuminates, the catalytic con
verter could be damaged.
Continue driving
with reduced power (avoid
ing sustained high speeds and/or rapid accel
erat ions) and have the condition corrected .
Contact your author ized A udi dealer.
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information
Q page 2 7, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
Qpage231 .
On-Board Diagnostics
Fig. 21 Location of Data Li nk Conn ecto r (DLC)
On-Board Diagnostics monitors the compo
nents of your emission control system . Each
monitored component in your engine system
has been ass igned 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
Q page 231.
In order to make an accurate diagnosis , the
stored data can only be displayed using spe
cial diagnostic equipment (generic scan tool
f or OBD).
In order to connect the spec ia l diagnostic
equipment , push the plug into the Data Link
Connector (DLC). Th e DLC is located to the
right of the hood release
Qfig. 21.
Your authorized Audi dea ler or qualified work
shop can interpret the code and perform the
necessary repair.
~ ARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!

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 ope rated at excessive speeds,
your veh icle also has an elect ronic speed limit
er. The electronic speed limiter prevents your
ve hicle from going faster than the tire speed
rating. For more information
c::> page 259 .
If the engine control unit rece ives fau lty vehi
cle road speed signals, the Malfunction Ind i
cator Lamp (MIU¢• will illuminate . If this
occurs, contact the nearest authorized Audi
dea ler for assistance.
A WARNING
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traff ic and weather conditions. Never
drive your vehicle faster than the maxi
mum speed ra ting of the tires insta lled.
Auto Check Control
Introduction
The Auto-Check control monitors the function
of certain veh icle features and components. It
simply makes sure these features and compo
nents are work ing properly . The Auto-Check
control wo rks as long as the ignition is on, as
well as whenever the vehicle is driven .
If a component is malfunctioning or if the need for an urgent repair has been detected,
this wi ll appear in the instrument cluster dis
p lay. You will a lso hear a n aud ible warn ing
tone. The d isplays are color coded in either
red or yellow depending on their level of prior
