Chevrolet Sonic Owner's Manual: When the System Does Not Seem To Work Properly
If the LDW symbol does not appear:
- The lane markings on the road may not be seen.
- The camera sensor may be blocked by dirt, snow or ice.
- The windshield may be damaged.
- The weather may be limiting visibility.
This is normal operation; the vehicle does not need service. Clean the windshield.
Warning
LDW does not provide a warning to help avoid a crash, unless it detects the lane markings. LDW may not detect the lane markings if the camera sensor is blocked by dirt, snow, or ice, or if the windshield is damaged. It may also not detect a lane on winding or hilly roads, or in conditions that can limit visibility such as fog, rain, or snow, or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps, and camera sensors clean and in good repair.
LDW warnings may occasionally occur due to tar marks, shadows, cracks in the road, or other road imperfections. This is normal system operation, the vehicle does not need service.
