I couldn't find anything in the manual about this, and the two threads I found in the Tech forum didn't have authoritative answers, so I figured I'd ask here.

If I'm doing an underbody wash with a hose or at a car wash, is there anything I must be aware of with respect to the intelligent cruise laser window on the front grille? I just don't want to end up forcing water into it and causing myself issues in the future.

Edit: the manual does not state anything about this, that I could find. The only statements I found were on page 5-49 with respect to cleaning with a soft cloth and not putting stickers on it.

 

i'm 100% sure you don't need to worry about anything all this stuff is completely sealed and you shouldn't worry about water getting in anywhere. why would you want an underbody didn't you just get ur car ?

 

+1. It will be fine. I have pressure washed my little laser box and its fine.

If i floor it though, from a stop and pull onto a freeway. It flashes then i have to pull off again, shut the car down and let it 'reset'.

Anyone else have this problem?

 

You are quite correct - I just got it. I ask since I wanted to make sure I didn't do anything stupid that I'd regret later.

I plan on at least rinsing the car down every 2 weeks and trying to do a drive-thru car wash with underbody monthly to keep the salt off.

 

I recently had this problem. You are most likely low on brake fluid. I added fluid and never had the problem again.
