LANE DEPARTURE ALERT DESCRIPTION

1. The lane departure alert system uses the lane departure warning camera's image of the road in front to detect lane markers on either side of the vehicle. If the system detects that the vehicle is about to move out of its lane, the system uses the warning buzzer and multi-information display to warn the driver.

   However, in the following conditions, the lane departure alert system may not function normally.

   
   

   • When driving through an area with no lane markers, such as a tollbooth, a crossing or before a ticket checkpoint

   • When driving on a sharp curve

   • When lane markers are extremely narrow or extremely wide

   • When the vehicle leans to one side an unusual amount due to a heavy load or improper tire inflation pressure

   • When the following distance between your vehicle and the vehicle ahead is extremely short

   • When the lane markers are yellow (These may be more difficult for the system to recognize compared to white markers.)

   • When the lane markers are broken, Botts' dots (raised pavement markers) or stones

   • When the lane markers are on a curb etc.

   • When lane markers are obscured or partially obscured by sand, dirt, etc.

   • When there are shadows on the road running parallel with lane markers, or if a shadow covers the lane markers

   • When driving on a particularly bright road surface, such as concrete

   • When driving on a road surface that is bright due to reflected light

   • When driving in a location where the light level changes rapidly, such as the entrance to or exit from a tunnel

   • When sunlight or the headlights of oncoming vehicles are shining directly into the camera lens

   • When driving on roads that are branching or merging

   • When driving on a road surface that is wet due to rain, previous rainfall, standing water, etc.

   • When the vehicle experiences strong up-and-down motion such as when driving on an extremely rough road or on a seam in the pavement

   • When headlight brightness at nighttime is reduced due to dirt on the lenses, or when the headlights are misaligned

   • When driving on winding roads or roads that are uneven

   • When driving on rough or unpaved roads

SYSTEM OPERATION

1. Lane departure warning function:

   The lane departure warning function operates when the lane departure alert main switch is on, the vehicle speed is between 50 km/h (31 mph) and 180 km/h (112 mph), and lane markers on the road surface are detected. With the departure warning function operating, if the vehicle is about to move out of the lane and this is detected by the lane departure warning camera, the system uses the warning buzzer and the multi-information display to warn the driver.

   Tech Tips

   This function only provides suggestions for lane departure avoidance. This function does not automatically move the vehicle back into the lane.
