If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the hill- start assist
control system can no longer operate. In
this case, stop your vehicle immediately at
a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous
sounds for about 3 seconds.)
At this time, the slip indicator light will
come on and the hill- start assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the hill- start assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.
