Instrument s and warning /indicator lights
Open door/hood/rear lid warning
Fig. 14 D isplay: doors and rear lid open
With the ignition switched on, the warning il­
luminates when at least
one door or the hood
or the rear lid is not closed. The symbol also
shows you
which door(s) or lid is not closed.
In the illustration ¢
fig. 14 it is the driver's
door and the left rear door.
On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢4 in
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 work ing 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
erat ions) and have the condition corrected.
Contact your author ized Audi dealer.
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
in formation ¢
page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may a lso
cause the MIL light to illuminate¢
page 225.
On-Board Diagnostics
Fig. 15 Location of Data Link Connector (DLC)
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
funct ion, 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 ¢
page 225.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD).
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. 15.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING
Do not use the diagnost ic connector for
personal use. Incorrect usage can cause
malfunctions, wh ich can increase the risk
of a collision!

Electronic speed limiter
Your veh icle may be factory equ ipped 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 limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed rating. For more informat ion
c::> page 259.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIU¢• will illuminate . If this
occurs, contact the nearest authorized Aud i
dealer for assistance.

Your vehicle's top speed is electronically limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty vehi ­
cle roadspeed signals, the Ma lfunction Indica­
tor Lamp (MIU ¢.id will illuminate. If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
A WARNING
-
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.
