Don't read anything about free reapplications in the info package, just that a kit of items came with the car. But worth a call to the dealer.
The paint is clear coated and would be concerned about scratching if polishing incorrectly or even the need to polish. Suggest a good wash and wax following similar methods in the link below:
How To Wash Your Car - At-Home Professional Car Wash Techniques
Granted the link is a commercial but take note of what is used to such as micro fiber, sheep's skin, mild detergent, etc. The wrong towel can scratch the clear coat. Also take note of the type of water used, hard water can leave water marks if allowed to dry. The auto soap would have water softening chemicals. Then follow with a spray wax.
Unless the paint clear coat has issues, there should be no need to polish or clay bar.
You can buy Toyoguard wax/sealant but other products are just as good or better.
