Drive slowly and avoid sudden, hard brake applications .
• If the brake warning /indicator light doe s 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 sy stem inspected .
• Always keep in mind that after several brake applications, you

power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident . •
