[ i] Tips
Many functions are monitored by the Auto -Check system
=> page 28 . Ma lfunctions or faults wil l be identified either with a red
symbo l (pr iority 1
-Danger!) or with a yel low symbol (priority 2 -
Warning) .•
Electronic power control EPC
This warning/indicator light monitors the electronic
power control.
The EPC warning/indicator light (Electronic Power Control) i llumi ­
nates when you turn on the ignition as a function chec k.
[ i ] Tips
If this warning/indicator l ight i lluminates whi le you are driving, then
there is a malfunction in the engine electronics . Have the malfunc­
t ion corrected as soon as possible by your authorized Audi dea ler or
qualified repair facility .•
Generator D
This 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
igni tion and must go out a fter 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 vehic le battery is discharging, you should switch off any unnecessary elec
­
t rical consumers (for example, the air conditioner).
0 Note
If the _f_ 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 water pump is not working
-this can cause engine damage. •
Electronic stabilization program (ESP) f1.
This warning/indicator light monitors the electronic stabi ­
lization program.
Th e warning/indicator light has the following functions:
• I t blinks while you are driving when the ESP is working .
• It illuminates when you switch on the ignition for approximate ly
2 seconds as a function check.
• It illuminates when there is a malfunction in the ESP. The
message
ESP fault! See owner's manual also appears in the instru­
ment cluster display and a warning tone sounds .
• It illuminates continuously when the ESP is switched off.
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS sys tem.
If the battery terminals were disconnected and re-connected , the
vehic le was jump sta rted or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates. The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporarily switched off the ESP . If this is case, you can reactivate
th e ESP by turning the ignition off and then on again . The

& WARNING
• USA models: If the BRAKE warning light , the $';. warning light 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 . Ha ve your vehicle repaired
immediately by your authorized Audi dealer or a qualified work­
shop. Drive slowly and avoid sudden , hard brake applications.
• Canada model s: If the brake warning light
(CD) , the ~ warning
light and the ABS warning light

wheels could lock up first under hard braking. Rear wheel lock-up
can cau se los s 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.
• 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 , pro ceed 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 a ccident . •

h _e _ ro_ a_d __________________________________________________ _
Starting off with a trailer To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough forward momentum at the wheels as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating -just as you would when starting on a
hill with a conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- Pull the switch and continue to pull it to slow your vehicle
with the parking brake in an emergency.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . The vehicle is
braked at all four wheels by activating the hydraulic brake system.
Brake performance is similar to making an emergency
stop~ &.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as the switch is released
, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The laws
of physics cannot be suspended even with ESP and its associated
components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away -risking an
accident. •
Driver messages in the instrument cluster
Caution: Vehicle parked too steep
This message appears when the parking brake is applied on an
incline that exceeds about 30%.
In this case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Please release parking brake
This message appears, when a gear is selected and the accel erator
pedal is depressed -release the parking brake.
Press brake pedal to release parking brake
This driver message appears when the switch to release the parking
brake was pressed. The parking brake can only be released if you
press the brake or accelerator pedal and press the switch at the
same time .
~ Parking brake malfunction !
This driver message appears together with the yellow 'Jlf symbol
when there is a parking brake malfunction.

General information
The HomeLink® feature can learn up to three radio
frequency codes for most current transmitters used for
operating garage doors, estate gates, home or outdoor
lighting systems, and other devices.
You must first program the Homelink® transmitter before you can
use the
system=> page 191, "Programming the Homelink® trans­
mitter".
In order to program the Homelink® transmitter for devices utilizing
rolling code , a second person on a ladder who can safely reach the
garage door opener motor is recommended. It is also necessary to
locate the
"learn" button on your garage door opener motor . Refer
to the operating instructions for the opener, as the location and
color of this button may
vary by manufacturer.
You can still use the original remote control for the device at any
time.
& WARNING
• Never use the Homelink"" transmitter with any garage door
opener that does have not the safety stop and reverse feature as
required by federal safety standards. This includes any garage
door opener model manufactured before April 1, 1982.
• A garage door opener which cannot detect an object, signaling
the door to stop and reverse does not meet current federal safety standards . Using a garage door opener without these features
increases risk of serious injury or death.
Controls and equip­ ment
& WARNING (continued)
• For safety reasons never release the parking brake or start the
engine while anyone is standing in front of the vehicle.
• A garage door or an estate gate may sometimes be set in
motion when the Homelink® remote control is being
programmed. If the device is repeatedly activated, this can over­
strain motor and damage its electrical components -an over­
heated motor is a fire hazard!
• To avoid possible injuries or property damage, please always
make absolutely certain that no persons or objects are located in
the range of motion of any equipment being operated. •
