On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Ind icator 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 id
le 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
ing, a malfunction may ex ist in the engine 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 authori zed Audi dealer.
If the light illuminates, the electronic speed
limiter may also be malfunctioning . For more
information
¢ pag e 30, Electronic spe ed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 16 Locat ion o f Data Li nk Co nnector (DLC)
On-Board Diagnostics monitors the compo­
nents of your emission control system. Each
monitored component in your eng ine system
has been ass igned 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 refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed

Electronic speed limiter -
Your veh
icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). Thi s 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 limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed rating. For more information
c> page 251.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIU
¢1111i will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance .
S models
Your vehicle's top speed is e lectronically limit­
ed to 155 mph (250 km/h).

A WARNING
-
- When you lock your vehicle from outside,
nobody -especially children -should re­
main inside the vehicle. Remember,
when you lock the vehicle from the out­
side the windows cannot be opened from
the inside.
- When you leave the vehicle, always take
the ignition key with you . This will pre­
vent passengers (children, for example) from accidentally being locked in the ve­
hicle should they accidentally press the
power locking switch in the doors.
- Do not leave children inside the vehicle
unsupervised. In an emergency it would
be impossible to open the doors from
the outside without the key.
