Malfunction in the brake system
If the brake warning light <=>page 19 and
the ABS warning illuminate
together there
may be a malfunction in the ABS, and there
may also be a malfunction in the brake system
itself <=>,&. .
In the event of a
malfunction in the brake
system
the warning/indicator light 1111
(USA models);III (Canada models) in the in­
strument cluster flashes. By pressing the
ICHECKI button, you can bring up a driver
message which explains the malfunction in
more detail. Please note
<=>pag e 32.
Malfunction in the electronic differential
lock (EDL)
The EDL works together with the ABS. The
ABS warning light will come on if there is a
malfunction in the EDL system

See your authorized Audi dealer as soon as
possible.
.&, WARNING
-
- If the f!B (USA models);tlJ (Canada

standard brakes (without ABS). You will
not have the protection ABS provides.
Contact your authorized Audi dealer as
soon as possible.
- If the
1111 (USA models)/ . (Canada
models) brake system indicator light
turns on together with the ABS and ESC
indicator lights, the ABS/ESC regulating
function may have failed. Functions that
stabilize the vehicle are no longer availa­
ble. 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 corrected.
:l~ /(® ) Parking brake
The indicator light monitors the parking
brake.
When the parking brake is applied and the ig­

on.
It goes out after the engine has been
started . This indicates that the brake warning
light is functioning properly.
If the brake warning light does not light up
when the engine is cranking, there may be a malfunction in the electrical system. In this
case, contact your Audi dealer.
If the brake system warning/indicator light
flashes, there is a brake system malfunction .
By pressing the

Outside temperature display
Fig. 11 Display : outside temperature
At temperatures below 41 °F (+S °C) a snow­
flake symbol appears ahead of the tempera­
ture display . It is intended to remind the driv­
er to pay spec ial attent ion to
ic e on the roa d.
If the vehicle is stationary, or if you are driving
at a very low speed, the temperature shown in
the display might be slightly higher than the
actual outside temperature . Th is is caused by
the heat being rad iated from the engine .
If you have selected the °C (degrees Celsius)
unit for temperature in the MMI, the outside
temperature display also appears automat i­
cally in
°C.
A WARNING
- Never rely excl usively on the outside
temperatu re d isplay to determine if a
road surface is icy or not . Keep in mind
that road surfaces, especially bridges
and overpasses, could be ice covered and
s li ppery even at an outs ide temperature
above 41 °F (+ S °C).
- Always remember, even if the "snow­
flake" symbol (ice warn ing) does not ap­
pear 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 encountering icy road s urfaces increases .
Digital speedometer
Fig. 12 Display: Digi tal speedometer
Current speed appears in the disp lay. Speed is
shown in 1 mph measures (USA models) or 1
km/h measures (Canada models) .
You can switch the disp lay from m iles to kilo­
meters and vice versa via the MMI.
Open door or trunk lid warning
The pictogram alerts you when doors or the
rear lid have been left open .
Fig. 13 Display: open doo r or rea r lid wa rning
With the ign it ion sw itched on, the ope n door
or rear lid warning illuminates when at least
one door or the hood or the trunk lid is not
cl osed . The symbol a lso shows you
which
doo r(s) o r lid is not closed.
In the illustration
~ fig . 13 it is the dr iver's
doo r, the left rear door and the rear lid. As
soon as all the doors, the hood, the rear lid
and the f uel filler cap are prope rly closed, the
door and rear lid warning turns off and the
Driver Information System functions selected
are displayed again.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (M IL) ("4 in
the instrument cluster¢
page 14, fig. 8 is
part of the On-Board Diagnos tic (OBD II) sys­
tem .
The warning/ind icator light ill um inates when
the ignition is switched on and goes out after
the engine star ts and the id le has stabilized.
This indicates that the M IL is working prope r­
ly .
If the light does not go out after the engine
is started , or illumina tes while you are dr iv­
ing, a malfunction may exist in the engine sys ­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Con tinue driving
with reduced powe r (avoid­
ing sustained high speeds and/or rapid accel ­
erations) and have the cond ition co rrected .
Contact your a uthorized Aud i dea ler.
If the light illum inates, the elec tronic speed
limiter may also be malfunctioning . For more

On-Board Diagnostics
Fig. 22 Locat ion 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
function, the component will be ident ified
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 fue l vapor recovery sys­
tem.
If the light illuminates after a refuelling ,
stop the veh icle and make sure the fuel filler
cap is proper ly closed (on ly vehicles with gaso­
line engine)

In o rder to make an accurate d iagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD).
I n o rder 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

Your author ized Audi dealer or qualified work­
shop can interpret the code and perform the
necessary repair.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
ma lfunctions, which can increase the risk
of a collis ion!
Electronic speed
limiter
Your vehicle may be factory equipped w ith
t ir es 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 fa ilure a nd loss of contro l if
the vehicle is operated at excessive speeds,
your vehicle also has an elec tronic speed limit­
er . The e lectronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information
c::> page 284.
If the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica ­
tor Lamp (MIL)
II 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 cond itions . Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.

warning symbol appears in the display.
The speed warning system has
two warning
thresholds
that function independently of
each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maxi­
mum speed while you are driving. This setting "'
