You must keep your hands on the steering wheel at all times.
When an external condition cancels the system, for example, no lane markings are available and your hands are on the steering wheel, a tone sounds and a message appears in the instrument cluster display.
When an external condition cancels the system, for example, no lane markings are available and your hands are not on the steering wheel, the system immediately alerts you to take control of the vehicle. If this alert is ignored, the system slows the vehicle while maintaining steering control.
Cruise Control Reset Button  If your vehicle starts to slow down, you must contribute to the steering control and press and release the button or briefly press the accelerator pedal to regain full system performance.
Automatic cancellation can also occur if:
  • The lane becomes too wide or narrow.
  • The system cannot detect valid lane markings.
  • Lane markings are crossed.
  • The curve of the road is too sharp.
Note:   The system disables until the next key cycle if your vehicle slows down due to driver inactivity twice within a key cycle.
You initiate a cancellation when the system is active and you switch the turn signal lamp on. The system immediately cancels. The system remains in standby mode as long as the turn signal lamp is engaged. The system automatically re-activates once the vehicle is centered in a lane and the turn signal lamp is switched off.
