[ i ) Tips
Many functions are monitored by the Auto -Check system
=>
page 30. Malfunctions or faults wil l be identified either with a red
symbo l (pr ior ity 1 -Danger!) or with a yellow symbol (priority 2 -
Warning). •
Electronic power control r
This warning/indicator light monitors the electronic
power control.
The warning/indicator light (E lectronic Power Control) illumi -
nates when you turn 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 repair faci lity .•

battery is discharging, you shou ld switch off any unnecessary elec ­
trical consumers (for examp le, the air conditioner).
0 Note
If the _f_ warning/indicator light (malfunction in the engine coo ling
system) in the instrument cluster shou ld illuminate=>
page 33, stop
the vehicle and turn off the engine . The water pump is not work ing
- this can cause engine damage. •
Electronic stabilization program (ESP)
This warning/indicator light monitors the electronic stabi ­
lization program.
The 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 approximately
2 seconds as a function check.
• It il luminates when there is a malfunction in the ESP.
• It illuminates when ESP or ASR (Anti-S lip Regulation) is deacti­
vated .
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the battery terminals were disconnected and re-connected, the
vehicle was jump started or the battery is
very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light i lluminates . 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
te mporarily switched off the ESP. If this is case, you can reactivate
the ESP by turning the ignition off and then on again . The
warning/indicator light should go out to show that the system is
fully functional again.

& WARNING (continued)
• Canada models: If the brake warning light «D> 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. •
