Driving
■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●When the power switch is turned off
●If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases
■Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collision while
the vehicle is in motion.
However, the system does not operate in any of the following situations.
●The vehicle speed is below 6 mph (10 km/h)
●Components are damaged
■Secondary Collision Brake automatic cancellation
The system is automatically canceled in any of the following situations.
●The vehicle speed drops below approximately 6 mph (10 km/h)
●A certain amount of time elapses during operation
●The accelerator pedal is depressed a large amount
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering 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 hybrid system
off. The EPS system should return to normal within 10 minutes.
