Instruments and warning/indicator lights
& WARNING (continued)
• Canada models: If the brake warning light «D> 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 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 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. •

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU ~ in the instrument cluster
~ page 17, fig. 7 is part of the On-Board Diagnostic (OBD ID system.
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . 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 malfunction may exist in the engine system.
If the light starts flashing, the catalytic converter 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 327. •
On-Board Diagnostics
Con tro ls and eq uip
ment
Fig . 16 Location of
Data Link Connector
(D LC )
Driver information display
On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine sys tem
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
module memory .
The M IL light may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
~ page 327.
In order to make an accurate diagnosis, the stored data can only be
d isplayed using special diagnostic equipment (generic scan tool for
08D).
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. 16.
Your authorized Audi dealer or qualified workshop can interpret 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 359.
If the engine control unit receives faulty vehicle roadspeed signa ls,
the Malfunction Indicator Lamp (MIU will i lluminate . If this
occurs, contact the nearest authorized Audi dealer for assistance. .,.
