The LAS goes on stand-by when any of the following conditions is met. The LAS is automatically restored when its operation conditions are met.

  • The vehicle speed is less than about 56 km/h (35 mph).

  • The accelerator pedal is depressed abruptly.

  • The TCS/DSC is operating.

  • The TCS is turned off.

  • The steering wheel is operated.

The function is temporarily stopped.

The LAS stops functioning in the following cases:

  • The temperature in the forward sensing camera (FSC) is too high or too low.

  • The windshield around the forward sensing camera (FSC) is foggy.

  • The windshield around the forward sensing camera (FSC) is blocked by an obstruction, causing poor forward visibility.

  • Strong light (such as sunlight, or headlights (high-beam) of on-coming vehicles) is directed at the forward sensing camera (FSC).
