nal is also given.
A WARNING
- Always observe the warnings in
c::> page 216, before open ing the hood and
checking the brake fluid .
- Dr iving with low brake fluid is a safety haz­
ard . Stop the car and get profess ional assis -
tance .
1111>

-If the 1111 (USA models) . (Canada mod­
els) brake system indicator light turns on to­
gether with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
have failed. Functions that stabilize the ve­
hicle are no longer available . This could
cause the vehicle to swe rve and increase the
risk of sliding. Drive carefully to the nearest
authorized Audi dealer or other qualified
workshop and have the ma lfunction correct ­
ed.
- If the brake warn ing/ indicator light does
not go out after a few seconds and the park­
ing brake is re leased, or lights up while you
are driving, the flu id 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 w ith
maximum stopping power in critical situa­
tions . You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.

tromechanical parking brake.
