how to do. thanks

Answer
Just to be sure your doing it correctly:

Simultaneously push and hold the RANGE and RESET keys for 5 to 60 seconds and release them. The indicator will reset to 100.

If not you will need PICTURES showing you what to do. Contact me at: onlineautohelp@msn.com as you either have a faulty instrument panel cluster, A faulty BCM (computer) or a wire failure.
