If a warning light turns on or a warning buzzer sounds...
Stop the vehicle immediately. Continuing to drive the vehicle may be dangerous.
The following warning indicates a possible problem in the brake sys-
tem. Immediately stop the vehicle in a safe place and contact your
Toyota dealer.
*: Parking brake engaged warning buzzer: The buzzer sounds to indicate that
the parking brake is still engaged (with the vehicle having reached a speed
of 3 mph [5 km/h]).

This light also comes on when the parking brake is not
released. If the light turns off after the parking brake is fully
released the system is operating normally.
Calmly perform the following actions if any of the warning lights turn
on or flash. If a light turns on or flashes, but then turns off, this does
not necessarily indicate a malfunction in the system.
