A WARNING
- USA models: If the 1111 warning l ight
and
the m warning light come on to ­
gether, the rear wheels could lock up
first under hard braking . Rear wheel lock ­
up can cause loss of vehicle control and
an acc ident. Have your vehicle repaired
immediately by your authorized Audi
dealer or a qualified workshop . Dr ive
slowly and avoid sudden, hard brake ap·
plicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light
II]
come on together, the rear wheels could
.
lock up first under hard braking . Rear
wheel lock-up can cause loss of vehicle
control and an accident . Have your vehi­
cle repaired immed iately by your author·
ized Audi dealer or a qualified workshop .
Drive s low ly and avoid sudden, hard
brake applications.
- If the brake warning/ind icator light does
not go ou t after a few seconds and the
pa rking brake released, or lights up wh ile
you are driv ing, the fluid level in the
brake fluid reservoir is too low. If yo u be ­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest
author ized Audi dealer or qualif ied repair
facility and have the brake system in·
spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations. You must allow fo r
increased braking dis tances. The extra
distance used up by fading brakes could
lead to an accident.

Driver information
display
Introduction
General notes
The driver informa tion display inside the in­
strument cluster provides you, the driver,
with much useful information.
Fig. 9 Instr ument cluster: center d isplay
Information from the driver information sys­
tem is shown in the display in the center of
the instrument cluster.
When you turn on the ignition and while you
are driving, some functions and vehicle com­
ponents are scanned for their operating sta­
tus. Malfunctions or required service proce­
dures are signaled audibly and shown by red
and yellow lighted symbols and rem inders to
the dr iver in the display.
The driver is also shown information about ra­
d io and CD operation and directions for the
nav igation system*. You can find add itional
i n formation on these subjects in the M MI
manual.
The illustrations in the instrument panel dis­
play differ in some of the vehicles .
The driver information system provides the
following functions:

Outside temperature display
Fig. 11 Display : outside te mperature
At temperatures below 41 °F (+S °C), a snow­
flake symbol appears in front of the tempera­ ture display . It is intended to remind the driv ­
er to pay spec ial attent ion to
ic e on the roa d.
If your vehicle is stat ionary or if you are driv­
ing at very low speeds, the temperature dis­
played may be slightly higher than the actual
temperature outside due to the heat radiating
from the eng ine .
The unit of measurement for the temperature
can be set in either °For in °Con the MM I* or
on the radio control un it . The outside temper­
ature display automatically shows the unit of
measurement that has been set. For addition­
a l information, see the MMI* or the radio in­
struction manua l.
_& WARNING
- Never use the outside temperature d is ­
play to determine if a road surface is icy
or not. Keep in mind that road surfaces,
especially bridges and overpasses, could
be ice covered and slippery even at an
outside temperature above 41 °F (+S
0 ().
-Always remember, even if the "snow­
flake" symbol ( ice warn ing) does not ap­
pear i n the display, blac k ice could be on
the road.
- Always reduce you r speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road s urfaces increases .
'
(D Tips
-If the vehicle is stationary, or if you are
dr iving at a very low speed, the tempera­
t u re shown in the d isp lay m ight be
slightly h igher than the actual outside
temperat ure. Th is is caused by the heat
being radiated from the engine .
Gearshift Indicator
Applies to vehicles: wit h manual transmiss ion and gear ­
shift indicato r
This indicator can help conserve fuel.

Shifting sugg estion .
In order to become familiar with the gearshift
indicter, at first just drive the way you are
used to.
If the current gear -and the dr iv ing
s ituation - is not the best one for conserving
fuel, then the indicator will disp lay the recom­
mended gear . The display shows the current
gear and the gear that is recommended
r:::> fig . 12.
- Up shifting The display will light up to the
right of the gear cu rrently selected if it is
recommend ing a higher gear .
-Downshift ing: The display will light up to
the
left of the gear currently se lected if it is
recommend ing a lowe r gear .
Somet imes the i ndicator will recommend
sk ipping a gear (3
> 5).

If there is no gearshift recommendation, then
just drive in the appropriate gear for conserv­
ing fuel.
@ Tips
-This indicator can help you conserve fuel.
This indicator is not meant to show you
which gear you should a lways be in in all
driving situations. Sometimes, in s itua­
tions such as passing, driving through mountains or when towing a trailer,
there won't be any gearsh ift recommen­
dat ion.
- The display does not light up when the
clutch pedal is be ing depressed .
Digital speedometer
Fig. 13 Display : Dig ital speedo mete r
Current speed appears in the display . Speed is
shown in 1 mph increments (USA models) or 1
km/h increments (Canada models) .
You can switch the display from miles to kilo­ meters and vice versa via the MMI*.
Open door or trunk lid warning
The pictogram alerts you when doors or the
trunk lid have been le~ open.
Fig. 14 Display: Open doo r- and trunk lid warning
Driver information display 21
The Open Door/Trunk Lid warning displays if
even
one door, the hood or the trunk lid is

30 days before the next service is due, a serv ­
i ce reminder appears in the display when you
turn on the ignition
qfig . 15 .
After about 5 seconds the display switches
back to normal. The distance and time re­
main ing are updated each time the ignit ion is
turned on until the date due for serv ice is
reached.

Fuel economy messages
App lies to vehicles: with trip computer w ith eff ic iency
program
Fig. 22 Display: fuel economy message
F ue l economy messages are disp layed when
fuel consumption is increased by certain con­ ditions. If you follow these fuel economy mes­
sages, you can reduce your vehicle's consump­
tion of fuel. The messages appear automati­
cally and are only displayed in the efficiency program. The fuel economy messages turn
off
automatically after a certain period of time .
~ To turn a fuel economy message off imme-
diately after it appears, press the
I RESETI
button ¢ page 23, fig. 18@, or
~ Press the function selection switch
9page23, fig.18@.
(D Tips
-Once you have turned a fuel economy
message
off, it will only appear again af­
ter you turn the ignition on aga in.
- The fuel eco nomy messages are not dis­
played in every instance, but rather in in­
tervals over a period of time.
On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) flllifi in
the instrument clus ter
9 page 13, fig. 8 is
part of the On-Board Diagnostic (OBD II) sys­
tem .
The warning/indicator light illuminates whe n
the ign ition 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 dr iv­
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
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illum ina tes, the electronic speed
limiter may also be mal functioning. For more
information ¢
page 2 7, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
¢ page 234.
On-Board Diagnostics
Fig. 23 Location of Data Link Connector (OLC)
On-Board Diagnostics monitors the compo­
nents of your em iss ion contro l system . Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he 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¢
