Frequently Asked Questions

Why is my recline position slightly wrong?

A range/performance code means the sensor reads but not accurately, often from mechanical wear at the pivot.

Can I recalibrate the sensor myself?

Some vehicles allow it but most require a scan tool for the relearn procedure.

Does this affect crash safety?

No, the recline sensor is for memory convenience only.
