■
Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
●Vehicles without a smart entry & start system: When the engine switch is
turned to “LOCK” position
● Vehicles with a smart entry & start system: When the “ENGINE START
STOP” 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 VSC systems are turned off, automatic reactivation
will not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steer ing input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal after a little while.
■ Automatic deactivation of “TRACK” mode
Vehicles without a smart entry & start system
When the engine switch is turned to “LOCK” position after driving in
“TRACK” mode, the mode is automatically deactivated.
Vehicles with a smart entry & start system
When the “ENGINE START STOP” switch is turned off after driving in
“TRACK” mode, the mode is automatically deactivated.
■ 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 60 km/h (38 mph).
● The brake pedal is depressed in a manner that cause the system to
judge from the vehicle deceleration that this is a sudden braking opera-
tion.
