Frequently Asked Questions
Is the curtain airbag different from the side airbag?
Yes. The side airbag protects the torso and is located in the seat, while the curtain airbag protects the head and deploys from the roofline above the windows.
Can I still drive if only the curtain airbag is disabled?
It is not recommended. While other airbags may still function, the curtain airbag provides critical head protection in side impacts and rollovers.
What causes water intrusion into the A-pillar?
Common causes include clogged sunroof drains, failing windshield seals, and cracked weather stripping, all of which can direct water into the A-pillar wiring area.
