shop. Drive slowly and avoid sudden , hard brake applications.
• Canada model s: If the brake 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.

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 . •

Speed warning system
Overview
The speed warning syste m hel ps you to keep your driving
speed below a set speed limit.
T he speed warning system warns the driver if he exceeds a previ ­
ous ly stored maximum speed . A warn ing tone will sound as soon as
the vehicle speed exceeds the set speed by about 3 mph (3 km/hl. At
the same time, a warning symbol appears in the disp lay.
The speed warn ing system has
two w arning thre shold s that func ­
tion independent ly of each other and that have somewhat d ifferent
purposes :
Speed warning 1 8 {USA mod els l/8 {Canad a m odels)
You can use speed warning 1 to set the maximum speed whi le you
are driving . This setting will remain in effect until you turn off the
ign it ion,
assu ming that you have not changed or reset the setting .
T he speed warning symbol
8 (USA modelsl/ 8 (Canada models) in
t he warn ing 1 disp lay appears when you exceed the maximum
speed . It goes out when the speed falls below the stored maximum
speed.
T he speed warn ing symbol wi ll also go out if the speed
exceeds th e
stored maximum speed by more than about 25 mph ( 40 km/h) for at
l east 10 seconds. However, t his does not reset the stored maximum
speed .
Setting speed warning 1

S pe ed wa rning 2

Storing warning 2 is recom mended if you always want to be
reminded of a certain speed, for example when you are traveling in
a co untry that has a general maximum speed l imit, or if you do n ot
want to exceed a specified speed for winter tires.
