Camera Windshield Defrost Heater
The camera windshield defrost heater keeps the windshield in front of the IPMA clear of frost and ice. The IPMA uses input from the front camera and the ambient air temperature to turn the camera windshield defrost heater on and off. Voltage and ground is supplied to the heater by the IPMA. The heater may be commanded on if the ambient temperature is below 5°C (41°F).
System Display
When the lane keeping system is turned on, an overhead graphic of a vehicle and lane markings is displayed in the LH IPC display. If the lane keeping aid mode is selected when the system is on, a separate icon will also appear in the IPC. When the system is off, the lane marking graphics are not displayed. The overhead vehicle graphic may still be displayed if adaptive cruise control is enabled. While the system is on, the color of the lane markings change to indicate the system status.
Gray: Indicates the system is temporarily unable to provide a lane keeping aid or alert activation on the indicated side(s). This may be caused by:
- The vehicle speed is under the activation limit
- High sunload on the IPMA camera lens
- Too close to lane markings
- Lane markings are too narrow or wide
- Road has no or poor lane markings in the camera field-of-view
- Following vehicle in front too closely
- IPMA camera blocked
- Windshield dirty or damaged
- Standing water on road
- Environmental conditions (significant sun angles, shadows, snow, heavy rain or fog)
- Turn signal is active
- Vehicle is in a dynamic maneuver
- Tight curves on the road
Green: Indicates the system is available or ready to provide a lane keeping aid or alert activation on the indicated side(s).
Yellow: Indicates the system is providing or has just provided a lane keeping aid activation.
