I have been launching my new boat and noticed some things related to the parking brake..
I usually set the parking brake (habit) when on flat ground for typical driving.
When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off. The parking brake appears to be setting itself automatically.
I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.
When is the parking brake automatically engaged? Under what specific circumstances? Can the auto set parameters be changed?
I like the auto set feature. It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).
Thanks!
