I have a 2020 HR-V LX AWD, so I can’t answer specifically for that car but my 2024 Civic EX has all of the features as your HR-V EX and I have never turned off anything and have had no problems. I would assume that with any car that has automatic windshield wipers would be the only thing to turn off unless it’s a very old car with a power antenna and then you’d need to turn off the radio.

The short answer for your car, nothing that I know.

 

Thanks!

 

Make sure that "BRAKE HOLD" is not activated! Don't use it on snow covered roads either. Don't ask me how I know.

 

Interested in knowing what happened...

 

All of the automatic car wash that I use have a sign that says turn off the wipers, brakes and steering but that’s common sense even though the employee will point at it every time. Does the HR-V even have automatic wipers? I know that our Civic EX does not.
