& WARNING
• If the .. (USA models )/ ...,. (Canada models ) wa rning light
does not go out , or if it comes on while driving, the ABS system is
not working properly. The vehicle can then be stopped only with
the standard brakes (without ABS ). You will not have the p rotec­
tion ABS provides. Contact your authorized Audi dealer a s soon as
pos sible.
• USA models : If the BRAKE warning light and the M, warning
light come on together, the rear wheels could lock up fir st under
hard braking. Rea r wheel lock-up can cause loss of vehicle cont rol
and an accident . Have your vehicle repaired immediately by your
autho rized Audi dealer or a qualified work shop. Dri ve slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light 0 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 you r authorized Audi dealer or a qualified wo rkshop.
Drive slowly and avoid sudden , hard brake applications .•
Electromechanical parking brake

se cond s.
T he wa rn in g/ind icator light will go out when the parking brake is
re lease d.
If the war ning/ indi cato r l ight flashes cont in uo usly
after applying the
park ing b rake, braking force is not sufficient to prevent the vehicle
fr om rolling unin ten tionally. Please note the following:
• If the slope of the ground is too steep to par k the ve hicle, the addi ­
tional drive message appears
Caution: Vehicle parked too steep .
• In the event of a pa rking b rake malfunction, the ye llow symbol

& WARNING
• USA model s: If the BRAKE warning light and the S warning
light come on togethe r, the rear wheels could lock up first under
hard braking . R ear wheel lock-up can cause lo ss of vehicle control
and an accident. Ha ve your vehicle repa ired immediately by you r
authorized Audi dealer or a qualified work shop. Driv e slowly and
avoid sudden , hard brake applications.
• Canada model s: If the brake warning light(@ and the ABS

first under hard braking. Rear wheel lock-up can cau se lo ss of
veh icle cont rol and an accident . Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.
Drive slow ly and avoid sudden, hard brake applications .
• If the brake warning/indicator light doe s not go out after a few
seconds and the parking brake released, or lights up while you are
driving , the fluid level in the brake fluid rese rvoir is 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 th e brake pedal to stop your vehicle .
Do not rely on strained brakes to respond with maximum stopping
power in critical situation s. You must allow for increased braking
distances. 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 .

Information from the driver information system is shown in the
display in the center of the instrument cluster.
When you tu rn on the ign ition and while you are driving, some func­
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 .
T he driver is a lso shown information about radio and CD operation
and directions for the navigation system*. You can find additional
information on these subjec ts in the MMI manual.
The illustrations in the instrument panel display differ in some of the
vehicles.
The driver information system provides the follow ing functions: Sound system display

If your vehicle is stationary or if you are drivi ng at very low speeds, the
t empe ra tu re disp layed m ay be s light ly hig her t han the ac tual
temperature outside due to the heat rad iat ing from the engine .
T he unit of measurement for the temperature can be set in either °F
or in °Con the MM I* or on the radio co ntrol unit. The ou ts ide tempe r­
ature display automatically shows the unit o f measurement that has
been set. For ad ditio nal info rmation, see t he MM I* or the r adio
instruction manual.
& 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
warning ) does not appear in the di splay, black ice could be on the
road.
• Always reduce your speed and drive with special care in cold
weathe r conditions when the chance of encountering icy road
s urfaces increa se s.
[I) Tips
• If the vehicle is s tat io nary, o r if you are d riving a t a very low speed,
the temperature shown in the disp lay might be slightly higher than
t he act ual o utside temperature. This is caused by the heat being radi­
ated from the engine. •

In order to become familiar with the gearshift indictor, at first just
drive the way you are used to . If the current gear· and the driving
situation· is not the best one for conserving fuel, then the indicator
will display the recommended gear . The display shows the current
gear and the gear that is recommended~ fig . 11.
• Upshifting The display will light up to the right of the gear
currently selected if it is recommending a higher gear.
• Downshifting : The display will light up to the left of the gear
currently selected if it is recommending a lower gear.
Sometimes the indicator will recommend skipping a gear (3
> 5).
If there is no gearshift recommendation, then just drive in the appro­
priate gear for conserving fuel.
[I] Tips
• T his ind icator can help you conserve fuel. This indicator is not
meant to show you which gear you should always be in in all driving
si tuations. Sometimes, in situations such as passing, driving through
mountains or when towing a trailer, there won't be any gearshift
recommendat ion.

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warn ing/ind icator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicat es 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 co nverter 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 29, "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
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 fue l
vapor recovery system. If the light illuminates after a refueling, stop
the vehicle and make sure the fuel filler cap is properly closed
=;, page 271 .
In order to make an accurate diagnosis, the stored data can only be
displayed using specia l diagnostic equipment (generic scan too l for
OBD).
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=;, fig. 22.
Your authorized Aud i dealer or qualified workshop can interpret the
code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equ ipped 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 contro l if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating . For more information =;,
page 303.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Lamp (MIL) will illuminate . If this
occurs, contact the nearest authorized Audi dealer for ass istance. .,,_
