SRS/ Airbag Light Goes on When Driving Up the Same Hill

I live in the Cariboo, and when I drive south from 100 Mile House on the 97 up to the 24, by SRS light goes on every. single. time!!

sure, I'm gaining lots of altitude, but it doesn't happen when going higher in other places.

2011 X. 118k miles. This makes no sense.

Yelp?
