A WARNING
- USA models: If the 1111 warning l ight
and
the m warning light come on to ­
gether, the rear wheels could lock up
first under hard braking . Rear wheel lock ­
up can cause loss of vehicle control and
an acc ident. Have your vehicle repaired
immediately by your authorized Audi
dealer or a qualified workshop . Dr ive
slowly and avoid sudden, hard brake ap·
plicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light
II]
come on together, the rear wheels could
.
lock up first under hard braking . Rear
wheel lock-up can cause loss of vehicle
control and an accident . Have your vehi­
cle repaired immed iately by your author·
ized Audi dealer or a qualified workshop .
Drive s low ly and avoid sudden, hard
brake applications.
- If the brake warning/ind icator light does
not go ou t after a few seconds and the
pa rking brake released, or lights up wh ile
you are driv ing, the fluid level in the
brake fluid reservoir is too low. If yo u be ­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest
author ized Audi dealer or qualif ied repair
facility and have the brake system in·
spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations. You must allow fo r
increased braking dis tances. The extra
distance used up by fading brakes could
lead to an accident.

Outside temperature display
Fig. 11 Display : outside te mperature
At temperatures below 41 °F (+S °C), a snow­
flake symbol appears in front 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 your vehicle is stat ionary or if you are driv­
ing at very low speeds, the temperature dis­
played may be slightly higher than the actual
temperature outside due to the heat radiating
from the eng ine .
The unit of measurement for the temperature
can be set in either °For in °Con the MM I* or
on the radio control un it . The outside temper­
ature display automatically shows the unit of
measurement that has been set. For addition­
a l information, see the MMI* or the radio in­
struction manua l.
_& WARNING
- Never use the outside temperature d is ­
play 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 slippery even at an
outside temperature above 41 °F (+S
0 ().
-Always remember, even if the "snow­
flake" symbol ( ice warn ing) does not ap­
pear i n the display, blac k ice could be on
the road.
- Always reduce you r speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road s urfaces increases .

(D Tips
-If the vehicle is stationary, or if you are
dr iving at a very low speed, the tempera­
t u re shown in the d isp lay m ight be
slightly h igher than the actual outside
temperat ure. Th is is caused by the heat
being radiated from the engine .

Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time.
Fig. 16 Trip computer display: Average fue l mi leage
T he following information is con tinuously
evaluated by the trip computer and can be dis­
played sequentially in the instrument cluster
display:
Fuel range
The estimated cruising range in miles (km)
appea rs in the display. This tells you how far
your vehicle will be ab le to travel on the cur­
rent tank of fuel and with the same driving
style. The display changes in increments of 6
miles (10 km).
T he cruising range is calculated based on the
fuel consumption for the last 18 miles
(30 km). If you drive conservatively, the cruis­
ing range will increase.
Average fuel mileage
T he average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this display to adjust
your driving technique to achieve a desired
mileage.
Current fuel mileage
T he instantaneous fuel consumption in m iles
per gallon ( l/100 km) is shown in this display.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) flllifi in
the instrument clus ter
9 page 13, fig. 8 is
part of the On-Board Diagnostic (OBD II) sys­
tem .
The warning/indicator light illuminates whe n
the ign ition is switched on and goes out after
the engine starts and the idle has stabilized. T
his 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 dr iv­
ing, a malfunction may exist 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 condition corrected.
Contact your authorized Audi dealer .
If the light illum ina tes, the electronic speed
limiter may also be mal functioning. For more
information ¢
page 2 7, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
¢ page 234.
On-Board Diagnostics
Fig. 23 Location of Data Link Connector (OLC)
On-Board Diagnostics monitors the compo­
nents of your em iss ion contro l 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.
T he 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 234. .,..

In o rder to make an accu rate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic eq uipment (gener ic 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 re lease
c:> fig. 23.
Your authorized A udi dealer or qualified work­
shop can interpret the code and perform the necessary repa ir.
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) . Th is is less than the
maximum speed of you r vehicle. To reduce the
ri sk of s udden tire failure and loss of control if
t he veh icle is ope rated at excessive speeds,
your vehicle also has an electronic speed lim it ­
er . The electronic speed limiter prevents yo ur
ve hicle from going faster than the tire speed
rating. For more informat ion
c:> page 263 .
If the engine contro l unit receives fa ulty vehi ­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
¢1111ij) will i llum inate. If t his
occ urs, contact the nearest authorized Aud i
dealer for assistance.
A WARNING
Always observe the posted speed limits
and ad just you r speed to suit p revailing
road, t raff ic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires insta lled.
Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warning system wa rns if the driver
exceeds a prev iously stored maxim um speed.
A warning tone will sound as soon as the vehi-
Dri ver information di spla y 2 7
cle speed exceeds the set speed by about
3 mph (3 km/h). At the same time, a warning
symbol appears in the display. The symbo l's
appearance might be different in some mod­
els.
The speed warning system has two warning
thresholds that funct ion independent ly 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
will remain in effect until yo u turn off the ign i­
tion, assuming that you have not changed or reset the setting.
The . (USA mode ls)/ . (Canada models)
speed warning symbo l in the warning 1 dis­
play appears when you exceed the maximum
speed . It goes out when the speed falls be low
the stored maximum speed .
The speed warning symbol will also go o ut if
the speed exceeds the stored maximum speed
by more than about 2S mph (40 km/h) for at
least 10 seconds . The stored max imum speed
is deleted.
Speed w arning 2
Storing warning 2 is recommended if yo u al­
ways want to be reminded of a certain speed,
for example whe n you are trave ling in a coun­
try that has a genera l maximum speed limit,
o r i f you do not want to exceed a specified
speed for wi nte r tir es.
The . (USA models) . (Canada models)
speed warning 2 symbol appears in the dis ­
play when yo u exceed the sto red speed limit.
Unlik e warning 1, it will not go out unt il the
vehicle speed drops below the s to red speed
li mi t.
