'01 TUNDRA_U (L/O 0008) In freezing weather, warm the windshield with the defroster before using the washer. This will help prevent the washer fluid from freezing on your windshield, which can block your vision. NOTICE Do not operate the wipers if the windshield is dry. It may scratch the glass. 84 2001 TUNDRA (OM34416U)
