For the first 300 miles (500 km) of driving after a service, the display
will keep showing dashes. This
is NOT a malfunction . Rather, the
system needs the mileage to (re-)adjust to your driving
style. Only
then can it start generating and updating figures for the distance and
days until the next scheduled service .

operating without ABS support . You will not have the protection
ABS provides. Contact your Audi dealer as soon as possible.
• USA models : If both the BRAKE warning light and the ABS
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 authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden , hard brake application .
• Canada models : If both the brake warning light ((DJ and the ABS
warning light
0 come on at the same time , the rear wheels could

• 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 o f the ABS system.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporar ily switched o ff the ESP . If this is case, you can reactivate
the ESP by switching the ignition off and then on again . The
warning/indicator light should go out to show that the system is
ful ly functional again .
I f the battery terminals were disconnected and re -connected, the

& WARNING
• USA models : If the BRAKE 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 . 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
{(j)) and the ABS
warning light
0 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 u sed up by fading brakes could lead
to an accident . •

The driver information system updates important information in the center display in clear view of the driver . In an easy to understand
format, the display tel ls you how your vehicle is functioning
at th e
c urr ent m om ent .
For example, the display can te ll you how many
miles (ki lometers) you can still drive until it is time to bring your
vehic le to your authorized Audi dealer for a scheduled Maintenance
Service. This feature helps preventing costly repairs. It is just one of
many different items o f information available for recall. The display also gives you a "status report" whenever the

the vehicle is at a standstill, or if you are driving at a very low speed,
the tempe rature shown in the display might be s lightly higher than
the actual outside temperature. This is caused by the heat being
radiated from the engine.
Remember, your vehicle is equipped with air conditioning and if
you change the display from °F (Fahrenheit) to °C (Centigrade), then
the outside temperature will automatically be displayed in °C (Centi -
grade)~ page 128. ...
