Published
Quick Summary

This English page is based on the Japanese guide and keeps the same practical, safety-first focus.
Visibility is a safety item
Dirty glass, old wipers, oil film, and interior fogging can make rainy driving much more dangerous.
What to check
- Remove oil film from the windshield.
- Replace wipers that streak, chatter, or leave lines.
- Use defogging and air conditioning to control moisture.
- Apply water repellent only after cleaning the glass well.
Do not ignore small symptoms
If the windshield is hard to see through at night or in heavy rain, fix it before the next long drive.
