System Startup
AutoVue activates when the ignition is turned on. Lane departure warnings are active only when the vehicle is traveling at or above 37 mph (60 kph).
At start-up the system performs a self-test. It then plays a brief clip of the "rumble strip" alert sound, first through the left speaker, then the right. The green 'enabled' lamp on the 'LANE ALERT' switch and the 'LANE SRCHNG' dash indicator then illuminate. See Fig. and Fig..
Fig. 1, AutoVue Lane Alert Switch
Fig. 2, AutoVue Lane Searching Dash Indicator
The green 'enabled' lamp on the switch will go OFF under the following conditions:
-
the driver temporarily disables the system;
-
an active diagnostic trouble code (DTC) is present.
The lane searching dash indicator will remain ON under the following conditions:
-
vehicle speed is below 37 mph (60 kph);
-
an active diagnostic trouble code (DTC) is present.
Warning: If the system cannot discover right or left lane markings, the AutoVue Lane Departure Warning system may not deliver expected alerts or erroneous alerts may occur.
Missed and false alerts may occur in the following situations:
-
Lane markings are difficult to distinguish due to standing water, snow, ice, mud, sand, dirt, or other debris on the road.
-
Lane markings are hidden or obscured by heavy rain, fog, falling snow or sleet, or blowing smoke.
-
Lane markings are missing or faded.
-
Sun glare or other light sources blind the camera, obscuring lane markings or making other road markings (e.g. tar strips) look like lane markings.
-
The camera's view through the windshield glass is blocked or obscured by dirt, chips, cracks, or some other distortion.
-
The camera is mis-installed.
-
Headlights are not operating or are mis-aligned.
It is always the responsibility of the driver to remain vigilant and change driving practices to suit traffic and road conditions.
