[ i ] Tip s
Many functions are mon itored by the Auto -Check system
=> page 28. Malfunctions or faults wil l be identified either with a red
symbol (priority 1 - Danger!) o r w ith a yel low sy mbol (priority 2 -
Warning). •
Electronic power control I'
This warning/indicator light monitors the electronic
power control.
The warning/indicator light (Electronic Power Control) i llumi -
nates when you turn on the ignition as a function check.
[ i ] Tip s
If this warning/indicator light illuminates whi le you are driv ing, then
there is a malfunction in the engine electronics . Have the malfunc ­
tion corrected as soon as possible by your authorized Audi dea ler or
qualified repair facility. •
Electronic stabilization program (ESP) at.
This warning/indicator light monitors the electronic stabi­
lization program .
The warning/indicator light has the following functions:
• It blinks while you are dr iving when the ESP is working.
• It illuminates when you sw itch on the ignition for approximately
2 seconds as a function check.
• It illuminates when there is a malfunction in the ESP .
• It illuminates when ESP or ASR (Anti -Slip Regu lation) is deacti­
vated. • I
t 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 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 illuminates. The warning/indicator light
goes out as soon as the learning process is complete .
I f 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
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.

This warning/indicator light monitors the airbag and the
pretensioner systems.
The ~ (USA models) IJ.!r (Canada mode ls) warning light illuminates
for a few seconds each time you switch on the ignition .
If the ~ (USA mode ls)
tJ.! r (Canada models) warning light does not
go out, or if it i lluminates whi le you are driving, or if it starts to b link,
t hen there is a malfunction somewhere in the system. If the light
does not il luminate when you switch on the ignition, this a lso
means there is a malfunction .

Adaptive Air Suspension
+>
This warning/indicator light has the fol lowing functions:
• It illumin ates for a few seconds after the ignition is turned on as
function check and then goes out.
• If th e warning/indicator light illuminates or blinks continuously,
there is a system fault in the Adaptive Air Suspension. A system
fault can result in limited ride comfort and
low ground clearance.
Drive safely to the nearest authorized Audi dealer or qualified work­
shop, and have the fault corrected.
• If the warning/indicator light flashes, you should not drive the
vehic le. The flashing warning/indicator light points to an extreme
High level. A very
pronounced lifting of the vehicle (extreme High
level) can resu lt, for example, when a heavy load is removed from
the vehicle. As soon as the level has returned to normal, the
warning/indicator light stops flashing, and you can drive away.
• If the warning/indicator light flashes in conjunction with the
<::i:,
warning/indicator light, you should not drive off immedia tely in
order to prevent damage to the underbody. The two warning/indi ­
cator lights flashing together points to an extreme Low level. A very
pronounced lowering of the vehicle (extreme Low level) can resu lt,
for example, from a heavy load. As soon as the level has returned to
normal, the warning/ind icator lights stop flashing, and you can
drive away.

the ignition is switched on~
page 185, "Chassis controls".
• If the warning/ind icator light flashes in conjunction with the
warning/indicator light, you should not drive the vehicle immedi ­
ately in order to prevent damage to the underbody. The two
warning/indicator lights flashing together points to an extreme Low level. A very
pronounced lowering of the vehicle (extreme Low level)
can resu lt, for example , from a heavy load . As soon as the level has
returned to normal, the warning/indicator lights stop flashing, and

& WARNING
• USA models : If the BRAKE warning light and the Af'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 model s: If the brake warning light (Q)) 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 di stance used up by fading brakes could lead
to an a ccident. •
