page 238 . See
your authorized A udi dea le r as soon as poss ible .
& 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

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. •

Trip computer
Introduction
The trip computer gives you information on current and
average fuel mileage, average speed, fuel range and
driving time .
Fig. 15 Trip computer
di sp lay : Average fuel
mileage
The follow ing information is conti nuously evaluated by the trip
computer and can be displayed sequentially in the instrument cluster
display :
Fuel range
The estimated cruising range in miles (km) appears in the display.
Thi s tells you how far your vehicle will be able to travel on the current
tank of fuel and with the same driv ing style . The display changes in
increments of 6 miles (10 km).
The cruis ing range is ca lculated based on the fuel consumpt ion for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km) s ince you last cleared
the memory appears in this d isp lay. You can use this d isplay to adjust
your dr iving tech nique to achieve a des ired mileage. .,,.

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 ~
page 271. •

Data Link Connector (DLC)
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 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. .,,_
