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

distances . The extra distance used up by fading brakes could lead
to an a ccident . •

two w arning thre shold s that func ­
tion independent ly of each other and that have somewhat d ifferent
purposes :

speed . It goes out when the speed falls below the stored maximum
speed.
