Operating conditions of Active Cornering Assist
The system operates when the following occurs.
● TRC/VSC can operate
● The driver is attempting to accelerate while turning
● The system detects that the vehicle is drifting to the outer side
● The brake pedal is released

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.
