& WARNING
• USA models: If the BRAKE warning light and the I warning
light come on together, the rear wheel s could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident. Have your vehicle repai red immediately by you r
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light ((j)) and the ABS
warning light
~ 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 vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden , hard brake applications.
• If the brake warning /indicator light does not go out after a few
second s and the parking brake released , or lights up while you are
driving , the fluid level in the brake fluid reservoir i s too low. If you
believe that it is safe to do so , proceed immediately at low speed
to the neare st authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brake s to re spond with maximum stopping
power in critical situations. You must allow fo r increased braking
di stan ce s. The extra distance used up by fading brakes could lead
to an accident. •

Introduction
General notes
The driver information display inside the instrument
cluster provides you, the driver, with much useful infor­
mation.
Fig. 8 Instrument
cluster: center display
Information from the driver information system is shown in the

tions and vehicle components are scanned for their operating status. Malfunctions or required service procedures are signaled audibly and
shown by red and yellow lighted symbols and reminders to the driver
in the display.
The driver is also shown information about radio and CD operation
and directions for the navigation system*. You can find additional
information on these subjects in the MMI manual.
The illustrations in the instrument panel display differ in some of the
vehicles.

T he unit of measurement for the temperature can be set in either ° F

& WARNING
• Never use the outside temperatu re display to determine if a
road surface i s ic y or not . Keep in mind that road surfaces, espe­
cially bridges and o verpasses , could be ice covered and slippery
even at an out side temperature above 41 °F (+5 °C ).
• Always remember , even if the "snowflake " symbol (ice

[I) Tips
If the vehicle is s tat ionary, or if yo u are dr iv ing a t a very low speed, the
temperature shown in the d isplay m ight be slightly higher than the
act ua l ou tside tempe ra tur e. This is caused by the heat being radia ted

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
=;,
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warning/indicator light illuminates 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 the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates , the electronic speed limiter may also be
malfunctioning. For more information=;,
page 26, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to illuminate

Driver information display
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
wi ll 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 fuel
vapor recovery system. If the light illumi nates after a refueling , stop
the vehicle and make sure the fuel filler cap is properly closed

page 276.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l for
080).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the hood release=>
page 25, fig. 20.
Your authorized Audi dea ler or qualified workshop can interpret 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 veh icle. To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, you r ve hicl e also has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
t ire speed rating. For more information=>
page 307.
If the eng ine control unit receives faulty veh icle road speed signals,
the Malfunction Indicator Lamp (MIL)
11.... will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance .
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires
installed. •
Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver exceeds a previous ly
sto red maximum speed. A warning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
same time, a warn ing symbol appears in the display. The symbol's
appearance might be different in some models.
Th e speed warning system has
two warning thresholds that function
independently of each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maximum speed while you a re
driving . This setting w ill remain in effect until you turn off the igni­
tion, assuming that you have not changed or reset the setting .
Th e speed warning symbol
8 (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed.
It goes out when the speed falls below the stored maximum speed.
The speed warn ing symbol w ill also go out if the speed
exceeds the
stored maxim um speed by mo re than about 2S mph (40 km/h) for at
least 10 seconds . The stored max imum speed is deleted.

Engine oil level correct
If the symbol 't=7: flashes even though the engine oil level is correct,
please seek professional assistance . Do not continue driving . Do not
leave the engine running

(I] 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 ... :lo requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning ~ starts to flash before you respond to the low oil
level warning . By then, your engine may already have suffered
serious damage. •
