A WARNING
- Read and follow the warnings in
¢ page 236, Working in the engine com­
partment before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the
brake fluid level in the reservoir is too low,
and this increases the risk of an accident.
Stop the vehicle and do not continue driv­
ing. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If the brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize
the vehicle are no longer available. This
could cause the rear of the vehicle to
swerve, which increases the risk that the ve­
hicle will slide. Do not continue driving. See
an authorized Audi dealer or authorized
Audi Service Facility for assistance.
