A WARNING ,~
- If the 1111 (USA models)/ . (Canada mod­
els) brake system indicator light turns on to­
gether with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
have failed. Functions that stabilize the ve­
hicle are no longer available. This could
cause the vehicle to swerve and increase the
risk of sliding. Drive carefully to the nearest
authorized Audi dealer or other qualified
workshop and have the malfunction correct­
ed.
- If the brake warning/indicator light does
not go out after a few seconds and the park­
ing brake is 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 situa­
tions. You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.

Introduction
General notes
The driver information display inside the instru­
ment cluster provides you, the driver, with much
useful information .
Fig. 9 Instrument cluster: center display
Information from the driver information system
is shown in the display in the center of the instru­
ment cluster .
When you turn on the ignition and while you are driving, some functions and vehicle components
are scanned for their operating status. Malfunc­
tions or required service procedures are s ignaled
aud ibly and shown by red and yellow lighted sym­
bols and reminders to the driver in the display.
The driver is also shown information about radio
and CD operation and directions for the nav iga­
tion system* . You can find additional informat ion
on these subjects in the radio or
MMI" manual.
The illustrations in the instrument panel display
differ in some of the vehicles.

Fig. 11 Display: outside temperature
~ ,.._
9 a:
lll
At temperatures below 39 °F (+4 °C), a snowf lake
symbol appears in front of the temperature dis­
play.
It is intended to rem ind the driver to pay
specia l attent ion to
ic e on the r oad .
If the vehicle is stationary, or if you are driving at
a very low speed, the temperature shown in the
d isplay m ight be slightly higher than the actual
outside temperature. This is caused by the heat be ing radiated from the eng ine.
The unit of measurement for the temperature
can be set in either °For in °Con the
MMI* or on
the radio control unit. The outs ide temperature
d isp lay automatically shows the unit of meas ure­
ment that has been set. For add itional info rma­
tion, see the
MMI * or the radio instruction man ­
ua l.
_& WARNING
-Never use the outside temperature d isp lay
to determine if a road surface is icy or not.
Keep in m ind that road surfaces, especially
br idges and overpasses, could be ice covered
and slippery even at an outs ide temperature
above 39 °F (+4 °C).
- Always remember, even if the "snowflake"
symbol ( ice warn ing) does not appear in the
display, black ice could be on the road.
-Always reduce your speed and dr ive with
special care in cold weather conditions when
the chance of encounteri ng icy road surfaces
in creases.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster
c:::> page 14, fig. 8 is part of the
On-Board Diagnostic (OBD II) system.
The warning/indicator light i lluminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates 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 illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim­
iter may also be malfunctioning. For more infor­
mation
c::> page 26, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate (only vehicles
with gasoline engine)
c:::> page 216.
On-Board Diagnostics
F ig . 21 Locat ion of Data link Connector (DLC)
On-Board Diagnostics monitors the components
of yo ur emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
26
The MIL light may also illuminate if there is a
l eak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed (only vehicles with gasoline engine)
c::> page 216.
In order to make an accurate diagnosis, the stor ­
ed data can only be displayed using specia l diag­
nostic equipment (generic scan tool for OBD).
In order to connect the specia l diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC) . The DLC is located to the right of the hood
release
c::> fig. 21.
Your authorized Audi dealer or qualified work­ shop can interpret the code and perform the nec­
essary repair .
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the r isk of a coll i­
sion!
Electronic speed limiter
Your vehicle may be factory equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . Th is is less than the max imum speed
of your veh icle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is ope rat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
c::> page 242.
If the engine contro l unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL) ¢•will illuminate. If this occurs,
contact the nearest authorized Audi dealer for as­
sistance.

Your vehicle's top speed is electronically limited
to 155 mph (250 km/h).
