Safety System Check
Now and then, check that the safety belt reminder light, safety belts, buckles, latch plates, retractors, and anchorages are all working properly.
Look for any other loose or damaged safety belt system parts that might keep a safety belt system from doing its job. See your dealer to have it repaired. Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away.
Make sure the safety belt reminder light is working. See Safety Belt Reminders on page 5‑19 for more information.
Keep safety belts clean and dry.
See Safety Belt Care on page 3‑22.
