■ Automatic reactivation of Active TRC, VSC and Trailer Sway Control
Turning the engine switch off after turning off the Active TRC and VSC systems will auto-
matically re-enable them.
■ Automatic Active TRC reactivation
If only the Active TRC system is turned off, the Active TRC system will turn on when vehi-
cle speed increases.
■ Automatic Active TRC, VSC and Trailer Sway Control reactivation
If the Active TRC, VSC and Trailer Sway Control systems are turned off, the systems will
not turn on even when vehicle speed increases.
■ If the brake system overheats
The brake system may overheat. In this case, a buzzer will sound, and TRC OFF indicator
will flash, and Active TRC and hill-start assist control will be temporarily inoperable. In
this event, stop the vehicle immediately in a safe place, and allow the brake system to cool
down sufficiently until the TRC OFF indicator goes off. (There is no problem with con-
tinuing normal driving.)
■ Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will operate:
● The emergency flashers are off.
● Actual vehicle speed is over 55 km/h (35 mph).
● The brake pedal is depressed in a manner that cause the system to judge from the vehi-
cle deceleration that this is a sudden braking operation.
