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.

If the LDW camera sensor is blocked by dirt, snow, or ice, or if the windshield is damaged, it may not detect a vehicle ahead. LDW may not help avoid a collision under these conditions. Do not rely on LDW when the camera is blocked by snow, ice, or dirt. Keep the windshield clean.
