The ILI system operates above approximately:

When the vehicle approaches either the left or the right side of the travelling lane, the steering wheel will vibrate, a chime will sound (only when Steering Assist is active) and the ILI indicator (yellow) on the Vehicle Information Display will blink to alert the driver. Then, the ILI system will automatically apply the brakes for a short period of time to assist the driver to return the vehicle to the centre of the travelling lane.

The ILI system turns on when the Drive Assist or Speed limiter switch on the steering wheel is pushed when the [Lane Departure Prevention] is enabled in the [Driver Assistance] in the vehicle information display. The Drive Assist indicator illuminates on the vehicle information display.
