Okay,
Lets look in the IP fuse block, manual says it is on the right side of your dash.
We want to look at the park lamp fuse. it is fuse 20, says it is a 10 AMP.
Using a test light to check fuses is the best way, you can see if power is making it through, even if the fuse may be good (Bad blade contact in fuse block)
If it is bad/ burned/ blown always replace any fuse with the exact same amp as the one that goes there.
Your vehicle also has a parking lamp relay (Relay 28, same fuse block as fuse 20)
This could also be the problem... see guide below on relay testing
