Brake system
BRAKE (USA models) / (CD) (Canada models)
This warning/indicator light illuminates when the brake
fluid level is too low or when there is a malfunction in the
ABS, or when the parking brake is set.
The light illuminates when the ignition is turned on. It goes out after
the engine has been started and the parking brake is fully released.
This indicates that the brake warning light is functioning properly.
If the brake warning light does not light up when the engine is
cranking or the parking brake is applied, there may be a malfunction
in the electrical system. In this case, contact your Audi dealer. If the brake system warning/indicator light flashes, there is a brake
system malfunction.
If the ABS fails, the ABS warning /indicator light (USA
models)/
.J (Canada models) flashes together with the brake system
warning/indicator light:::::,& .
(USA models): If the warning light
BRAKE and the warning light
illuminate together, immediately contact your authorized Audi
dealer or qualified workshop to have all brake pads inspected

& WARNING
• USA models : If both the BRAKE warning light and the
warning light come on at the same time, the rear wheels could lock up first under hard braking. Lock-up of the rear wheel brakes
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
application.
• Canada models: If both the brake warning light CCi)) and the ABS
warning light come on at the same time, the rear wheels could
lock up first under hard braking. Lock-up of the rear wheel brakes
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
application
• 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 workshop 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 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. •

Anti-lock brake system
~ _ (USA models)/ .... (Canada models)
This warning/indicator light monit ors the A BS and the
electronic differenti al lock (EO L).
The ,I<-warning light wi ll come on for a few seconds when the igni ­
tion is switched on. The light will go out after an automatic check
sequence is completed.
There is a malfunction in the ABS when:
• t he war ning/in dicat or li ght does not illuminate when yo u switc h
on the ignition .
• th e warning/indicator l ig ht doe s no t go out after a few sec onds.
• the warning/indicator light illum inates while driving.
Without the electronic assistance of the ABS , the brake system will
still respond and br ake the car. Have the brake system che cked and
restored to its full performance by an authorized Audi dealer a s
soon as possible.
For more information regarding the ABS see
=> page 194 .
Since any malfunction of the ABS also affe cts the ESP, that system's
warning symbol •

Unspecific malfunction in the brake system
If bo th the brake warn ing lig ht=> page 15and the wa rn ing l ight

If an unspec ific defect in the brake sys te m i s indica ted, the e ntire
brake system is likely to be affected and you
must expect degraded

& WARNING (continued)
• Always remember, even if the "snowflake" symbol (ice
warning) does not appear in the display, 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 vehicle is stationary , or if you are driving at a very low
speed, the temperature shown in the display might be slightly
higher than the actual outside temperature. This is caused by the
heat being radiated from the engine.
• On vehicles with S tronic, the reminders do not appear in the
display until you select a gear .
• On vehicles with Audi Navigatio n system*, the displays may
differ from their normal appearance during navigation. •

On-Board Diagnostic system (08D)
On-Board Diagnostics

Data Link Connecto r
( DL C)
On-Board Diagnostics monitors the components of your emission
control system . Each controlled 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 lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system . If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed=>
page 227.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
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 engine hood re lease lever=>
page 21, fig. 10 .
Your authorized Audi dealer or a qualified service station can inter ­
pret the code and perform the necessary repair. •

Malfunction Indicator Lamp (MIL) (USA
models)/ (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 17, fig . 5 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 ma lfunction may exist in the engine system.
If the light starts flashing, the catalytic converter cou ld 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 27, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate => page 221. •
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, yo ur 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 257, "Speed rating
(letter code)".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfun cti on Indicator Light (MIU will illuminate . If this
occurs, contact the nearest authori zed Audi dealer for assistance. _.,

the vehicle speed exceeds the set speed by about 3 mph (3 km/h). At
the same time, a warning symbol appears in the display=> fig. 18.
The speed war ning system has
two warn ing thre shold s that func­
tion independently of each other and that have somewhat different
purposes :
