■
Automatic reactivation of TRC and Vehicle stability control (VSC) sys-
tems
After turning the TRC and Vehicle stability control (VSC) systems off, the
systems will be automatically reactivated in the following situations:
●
When the push-button ignition switch is turned off
●
If only the TRC system is turned off, the TRC will turn on when vehicle
speed is more than approximately 50 km/h (31 mph).
If both the TRC and Vehicle stability control (VSC) systems are turned
off, automatic reactivation will not occur when vehicle speed increases.
