switched on and will go out after the engine
is started and the idle has stabilized. This is
to assure you that the Malfunction Indicator
Lamp is working properly.
For more details, see page 128. Airbag
System AIR
BAG
The ind icator light for the airbag and belt
tensioner system must come on when
the ignition is switched on, and go out after
a few seconds. If the light does not go out,
or if it comes on while you are driving, this
ind icates a fault in the airbag I belt tensioner
syste m.
If the indicator light does not come on when
the ignition is switched on, this also indi­
cates a system malfunction. If any of these
conditions occur, have the air bag system in­
spected immediately by your authorized
Audi Dealer.

CONTROLS
AND EQUIPMENT---------------------
If there is an ABS problem:
o The ABS warning light to come
on. The vehicle can still be braked,
however, the ABS will not work. See
your authorized Audl Dealer as soon
as possible.
• The ABS warning light and the
brake warning light come on to­
gether. The ABS will not work and
you will notice a change in braking
characteristics and performance.
�W ARNING
If both warning lights (ABS and
BRAKE warning light) come on at
the same time, the rear wheels
could lock up first under hard
braking. Rear wheel brake lock-up
can cause loss of vehicle control
and an accident. Have your vehicle
repaired immediately by your au­
thorized Audi Dealer or a qualified
workshop. Drive slowly and avoid
sudden, hard brake application.
12 6 If
the ABS fails, the ESP warning light will
come on. See page and pages 202 -205.
Electronic differential lock (EDL)
The electronic differential lock works in con­
junction with the ABS system. A fault in the
ABS causes therefore a malfunction of the
electr onic differential lock.
For more details on how the EDL works, go
to page 204.
Brake
USA models:
BRAKE
Canada models:
(Q))
The light comes on while the engine is
cranking. It goes out after the engine has
been started and the parking brake is fully
released. This is your assurance that the
brake warning light is functioning properly. A If the brake warning light does ¥ not light up when the engine is
cra nking or the parking brake is ap­
plied, there may be a malfunction in
the electrical system. In this case,
contact your Audi Dealer.
When the light comes on, an audible warn­
ing signal is also given.
�W ARNING
• If both warning lights (ABS and
BRAKE warning light) come on at
the same time, the rear wheels
could lock up first under hard
braking. Rear wheel brake lock-up
can cause loss of vehicle control
and an accident. Have your vehicle
repaired immediately by your au­
thorized Audi Dealer or a qualified
workshop. Drive slowly and avoid
sudden, hard brake application.

WARNING continued
• If the brake warning light does
not go out with the engine running
and the parking brake released, or
lights up while you ere driving, the
fluid level in the brake fluid reser­
voir 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 workshop
and have the brake system in­
spected.
• Please be very careful and be
sure to remember that after sev­
eral brake applications, you will
need greater pressure on the brake
pedal to stop your vehicle. Conse­
quently, you must allow for in­
creased braking distances. Trying
to brake as quickly as usual could
lead to an accident.

This
light comes on when the ignition is
turned on and goes out after the engine is
started. If the light does not go out after
star ting and rewing up the engine momen­
tarily or lights up while driving, there may be
a malfunc tion in the electrical system, or the
V- belt driving the gener ator may be broken. A If the warning light comes on
V while driving, stop the vehicle
and turn oft the engine. Inspect the
belts.
If the V-belt is not torn, you can still continue
driving to the nearestAudi Dealer. However,

On Board Diagnostic system
The Malfunction Indicator Lamp (MIL)-see
page 125- is part of the On Board Diagnos­
tic system (OBD).
The lamp comes on when the ignition is
swi tched on and will go out after the engine
is started and the idle has stabilized. This is
to assure you that the Malfunction Indicator
Lamp is working properly.
If the lamp does not go out after the engine
is started, or if it comes on while you're
driving, there is a malfunction in the engine
system. If the lamp starts blinking, the cata­
lytic converter could be damaged.
Continue driving with reduced power
and have the cause corrected right away by
an authorized Audi Dealer or a qualified
workshop.
12 8 If the lamp comes
on, the Electr onic speed
li miter can also be out of operation. See
next page.
The On Board Diagnostics in your vehicle
monitors the various components of your
emission control system. Each controlled
component in your engine system has been
coded. In case of a malfunction the respec­
tive component in question will be identi­
fied and the fault stored in the form of a
code in the control module's memory.
On Board Diagnostic
System (OBD)
The stored data can only be displayed with
special testing equipment (generic scan
tool for OBDl to assure an accurate diagno­
sis.
To connect the special testing equipment,
push the plug into the Data Link Connector
(DLC) located to the right of the release le­
ver for the engine hood -see illus tration.
Yo ur authorized Audi Dealer or a quali fied
workshop can interpret the code and make
the necessary correction.

Electronic
speed limiter
Yo ur Audi may be factory equipped with
tires which are rated for a maximum speed
of 130 mph (21 0 km/h). This is less than the
maximum speed of your vehicle. To reduce
the risk of sudden tire failure and loss of
control should the vehicle be operated at ex­
cessive speeds, your Audi also has an elec­
tronic speed limiterwhi ch prevents your ve­
hicle from going faster than the tire speed
rating. See page 257.
If the vehicle approaches the tire speed rat­
ing, the engine control unit will shut off the
fuel injectors and you will notice an instant
Joss of engine power and drop in road
speed. The engine performance will return
to normal as soon as the speed has dropped
below approximately 125 mph (200 km/h).
If the vehicle road speed signal to
the engine control unit should fail,
the Malfunction Indicator Lamp will
come on.
If this occurs, see your authorized Audi
Dealer and have the cause located and cor­
rected. �W
ARNING
Always observe the posted speed
limits and adjust your speed to suit
preva iling road, traffic and
weather conditions. Never drive
your vehicle faster than the maxi­
mum speed rating of the tires
installed. CONT
