    No there is no light that tells you. Usually you will hear the belt make noise but inspect it for cuts and wear because if a belt breaks it could instantly ruin your engine. I recommend replacing both. It cost around $20 bucks for a new belt.

    Both of these have timing chains, So no maintenance is needed unless they get noisy or affect the timing

    you do not have a belt, you have a chain, does not need to be replaced as normal maintenance
