& WARNING
• USA models: If the BRAKE warning light and the warning
light come on together, the rear wheels could lock up first under
hard braking. Rear wheel lock-up can cause lo ss of vehicle control
and an accident . Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified work shop . Drive slowly and
avoid sudden, hard brake applications.
• Canada model s: If the brake warning light (CD) and the ABS
warning light :: come on together, the rear wheels could lock up
fir st under hard braking . R ear wheel lock -up can cause lo ss of
vehicle control and an accident. Have your veh icle 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 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 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 sy stem 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 brakes to re spond 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 . •

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

& 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.

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

intervals is vitally important to extending the life of your veh icle,
particularly the engine, and maintaining its value . Even if the mileage
dr iven is low, the maximum period of one year from one service to the
next must not be exceeded.

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunct ion Indicator Lamp (MIL) in the instrument cluster
=>
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e 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
whi le 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 accelerat ions) and have the condition corrected.
Contact your authorized Aud i dealer .
If the light illuminates, the electronic speed limiter may also be
malfunction ing. For more information=>
page 22, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
