A WARNING
-Always observe the warnings in

- Driv ing with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- If the . (USA

swerve and increase the risk of sliding .
Drive carefu lly to the nearest authorized
Audi dealer or other qualified workshop
and have the malfunction corrected.
- If the brake warning/indicator light does not go out after a few seconds and the
park ing brake is released, or lights up

immediately at low speed to the nearest
authorized Audi dealer or qualified work­ shop and have the bra ke system inspect­
ed.
- Always keep in m ind that after several
brake applications, yo u will need greater
pressure on the b rake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond w ith maximum stopp ing power
in critical situations. You must allow for
increased brak ing distances . The extra
distance used up by fad ing brakes could
lead to an acc ident.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢4' i n
the instrument cluster 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 proper­
ly.
If the light does not go out after the engine
is started, or illuminates while you are driv­
i ng, a malfunction may exist in the eng ine sys­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light il luminates, the electronic speed
limiter may also be malfunct ioning. For more
information

limiter.
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate

On-Board Diagnostics
Fig . 18 Locat io n of Data Link Con nector (D LC)
On-Board Diagnostics monitors the compo ­
nents of your emission control system . Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, 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 fuel vapor recovery sys­
tem. If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
