This warning/indicator light has the following functions :
• It illuminates for a few seconds after the ignition is t urned on as
function check and then goes out .
• If the warn ing/ind icator light illuminates or blinks continuously,
there is a system fault in the Adaptive Air Suspension . A system fault
can result in limited r ide comfort and
lo w gro un d cle arance. Drive
safely to the nearest authorized Audi dealer or qualified workshop,
and have the fault corrected .

& WARNING
• USA models: If the BRAKE warning light and the r i,~ 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 immediately by your
authorized Audi dealer or a qualified workshop . Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light (CD) 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 di ately 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
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake system inspected.
• Always keep in m ind that after several brake applications , you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brakes to respond with maximum stopping
power in critical situations. 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 .
Fig. 8 Instrument
cluster: center display
Informat ion from the Driver Information System is shown in the
display in the center of the instrument cluster.
When you tu rn on the ignition and while you are driving, some func­
tions and vehicle components are scanned for their operating status.
Malfunctions or required service procedures are signalled audibly and
shown by red and yellow lighted symbols and reminders to the driver
in the display .
Th e driver is also shown information about radio and CD operat ion
and directions for the navigation system. You can find additional
information on these subjects in the MMI manual.

& WARNING
• Never rely exclusively on the outside temperature display to
determine if a road surface is icy or not . Keep in m ind that road
su rfaces , especially bridges and overpa sses, could be ice covered
and slippery even at an outside 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
weather conditions when the chance of encountering icy road
surfaces increases.
(I] Tips
If the vehi cle is stat io na ry, or if yo u are driv ing at a very low speed, the

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 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 23, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate ~

Vehicle OP-eration
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 refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
~ page 275 .
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 . 15.
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 vehicle from going faster than the
tire speed rating. For more information ~
page 307.
If the engine con trol unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (MIL) will illuminate. If this
occurs, contact the nearest authorized Audi dealer for ass istance . .,.
