Instruments and warning/indicator lights
& WARNING
• Failure to heed warning lights and other important vehicle
information may result in serious personal injury or vehicle
damage .
• Whenever stalled or stopped for repair, move the vehicle a safe
distance off the road, stop the engine, and turn on the emergency
flasher
~ page 82.
• The engine compartment of any motor vehicle is a potentially
hazardous area. Before you check anything in the engine compart­
ment, stop the engine and let it cool down . Always exercise
extreme caution when working under the engine hood
~ page 242, "Engine compartment" .
[ i] Tips
Many functions are monitored by the Auto-Check system
~ page 28. Malfunctions or faults will be identified either with a red
symbol (priority 1 -Danger!) or with a yellow symbol (priority 2 -
Warning) .•
Malfunction Indicator Lamp (MIL)
L.i (USA models)/ (Canada models)
The Malfunction Indicator Lamp (MIU is part of the On-Board Diag­
nos tic (OBD Ill system. The symbol,.. lights up when the ignition is
turned on and will turn off after the engine has started and has
settled at constant idle speed . This indicates that the MIL is wo rking
properly.
The warning light illuminates when there is a malfunction in the
engine electronic syst em . Contact your authori zed Audi d ealer and
have the malfunction corrected.
For more information
~ page 27 . •

If an unspecific defect in the brake system is indicated, the entire
b rake system is likely to be a ffec ted a nd y ou mus t ex pec t degra ded
brake response and performance .
Since any malfunction of the ABS also effects the ESP, that system's
w arning symbol

(Canada models) warning light.
Malfun ction in the electronic diff erential lock
(EDL)
The two systems E DL and ABS inte ract. For this reason the ,t.
warning light/ 3 (Canada mode ls) wi ll come on to indicate a
malfunction in the EDL system~
page 213. See your authorized
Aud i deale r as soo n as poss ib le.
& WARNING
• If the ,.r;_/ :· (Canada models) warning light does not go out ,
or if it comes on while driving, the ABS system is not working
properly . The vehicle can then be stopped only with the brakes
operating without ABS support . You will not have the protection
ABS provides. Contact your Audi dealer as soon as pos sible.
• USA models : If both the BRAKE warning light and the "
warning light come on at the same time , the rear wheels could
lock up first under hard braking. Rear wheel brake lock-up can
cau se loss of vehicle control and an a ccident. Have your vehicle
repaired immediately by your author ized Aud i dealer or a qualified
work shop. Drive slowly and avoid sudden , hard brake application.
• Canada models : If both the brake warn ing light ((j)) and the ABS
warning light come on at the same time , the rear wheels could
loc k up first under hard braking . Rea r wheel brake lock-up can
cause loss of vehicle control and an accident. Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden, hard brake
application . •

If one of the turn signal light bulbs burn out, the turn signal will
flash twice as fast as normal. •
Electronic Stabilization Program (ESP)
The warning/indicator light monitors the electronic stabi­
lization program.
The warning/indicator light has the following functions :
• it flashes while you are driving , when the ESP is working .
• it illuminates when you switch on the ignition for approximately
2 seconds as a function check .
• it illuminates when there is a ma lfunction in the ESP.
• it illuminates after the battery has been disconnected.
• it illuminates continuous ly when the ESP is switched off.
• it illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the ESP warning/indicator light i lluminates and stays on after you
have started the engine , this may mean that the control system has
temporari ly switched off the ESP. If this is case, you can reactivate
the ESP by switching the ignition o ff and then on again. The
warning/indicator light should go out to show that the system is
fully functional again.
If the battery terminals were disconnected and re-connected, the
vehic le was jump started or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards.
During this time, the indicator light illuminates. It goes out as soon
as the learning process is comp lete .

Generator 0
T his warning/indicator light detects a malfunction in the
generator or in the vehicle's electrical system .
The D warning/indicator light illuminates when you switch on the
ign itio n and must go out after the engine has started.
If the
D warning/indicator light illuminates while you are driving,
you shou ld contact your authorized Audi dealer . Since the vehicle
battery is discharging, you should switch off any unnecessary elec ­
trical consumers (for example, the air conditioner) .
0 Note
If the -t warning/indicator light (ma lfunction in the engine coo ling
system) in the instrument cluster shou ld illuminate~
page 31, stop
the vehicle and turn off the engine. The coo lant pump is not working
- this can cause engine damage! •

Electronic power control p
This warning/indi cator light monitors the electronic
power control.
The warning/indicator light (Electronic Power Control) il lumi-
nates when you switch on the ignition as a function check .

[ i] Tips
If this warning/indicator light illuminates while you are driving, then
there is a malfunction in the engine electronics. Have the malfunc ­
tion corrected as soon as possible by your authorized Audi dealer or qualified workshop. •
Brake system BRAKE (USA models)/ (CD)
(Canada models)
This warning/indicator light illuminates when the brake
fluid level is too low or when there is a malfunction in the
ABS, or when the parking brake is set.
The light illuminates when the ignition is turned on. It goes out after
the engine has been started and the parking brake is fully released.
This indicates that the brake warning light is functioning properly.
If the brake warning light does not light up when the engine is
cranking or the parking brake is applied, there may be a malfunction
in the electrical system. In this case, contact your Audi dealer.
(USA models): If the warning light BRAKE and the warning light
illuminate together, immediately contact your authorized Audi
dealer or qualified workshop to have all brake pads inspected
=:> page 33.
When the light comes on, an audible warning signal is also given.
Parking brake set
The BRAKE or ((D) (Canada) warning/indicator light illuminates when
the parking brake is set=:>& .
& WARNING
• USA models: If the BRAKE warning light and the . J'l warning
light 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 vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light (CD) and the ABS
warning light _. 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 vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.
Drive slowly and avoid sudden, hard brake applications.
• If the brake warning/indicator light does not go out after a few
seconds and the parking brake 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 situations . You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident. •

Defective light bulb warning The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol with a message appears in the display to
tell you which bulb is burnt out and where it is located. For example:
R ear left tu rn signal
After 5 seconds, the message disappears . If you want to reca ll the
message into the display, press the CHECK button .
There are three reasons why the defective bulb message would appear in the display:
• the light bu lb has burnt out~
page 302.
• the fuse is "blown"~ page 300, "Replacing a fuse" .
• the wire connection to the light bulb is defective .
Have the bulb replaced or the connection repaired by your autho­
rized Audi Service department .
& WARNING
• Light bulb s are pre ssur ized and cou ld e xplode while they are
being changed causing se rio us pe rsona l injury .

Speed warning system
Overview
The spee d warning system helps you to keep your driving
speed below a set speed limit.
Fig. 19 D ispl ay : s pee d
wa rning sy st em
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 3 miles per hour (3 km/hl. At the same time, a warning symbo l appears in the display
~fig.19.
The speed warning system has
two warning thre sh old s that func­
tion independently of each other and that have somewhat different
purposes :
Speed warning 1
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect un til you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
C-~ (USA models)/ (Canada models) in
the warning 1 display appears when you exceed the maximum speed . It goes out when the speed falls below the stored maximum
speed. .,
~ehicle care Technical data

Driver information display
symbols appear in the instrument cluster display to alert the driver.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated .
The warning light _, also lights up during a system failure.
When the wheel is turning, the system receives radio signals from
sensors located inside each tire .
A factory spare wheel is delivered with sensor. However, the spare
wheel is not checked by the tire pressure monitoring system. Such monitoring can only occur after the spare wheel has been installed
and initialized ~
page 45.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0.1 bar). The tire warms up while the
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature.
In order to keep the tire pressure monitoring system properly cali­
brated, tire pressure on all four tires should be checked at regular
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure)~
page 43.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure label is located on the driver's side B-pillar. On
Canada vehicles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
~ page 277.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under -inflated. You should
stop and check your tires as soon as possible, and inflate them to
& WARNING (continued)
the proper pressure as indicated on the vehicle's tire pressure
label
~ page 271. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-infla­
tion also is likely to impair the vehicle's handling and stopping ability .
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
For the sake of the environment
Driving with under-inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when cold and set to the
recommended inflation pressure as specified on the tire pressure
table~
page 277 .
• The tire pressure monitoring system helps the driver to keep
track of the tire pressures . But the driver still has the responsibility
for maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves must not be
detached or exchanged. Only the valve core needs to be replaced
and, if necessary, the valve and the wheel electronics replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. .,
