Default GS450h (2015) - What Are These Sensors Behind the Mirror?

Friends,

There are 2 sensors behind the mirror of my 2015 GS450h...what are they? My car has Pre-Collision System (PCS), Lane Keep Assist (LKA) and Dynamic Cruise Radar. Are these 2 sensors related to these systems?

The owner's manual is not at all helpful in identifying these.

Many thanks,

T.V.

I believe the other one is for the rain sensing wipers.

yeah, that's the radar port for the PCS and adaptive cruise. Pretty sure I rolled through a section in the manual that points that out....I'll find a reference and post it.

The radar is behind the emblem on the front grill.

Agh damn. Haha. I knew I saw something about the rear view. I forgot that I saw the radar behind the front emblem. Thanks for the backup!

Default Sensors Behind the Mirror

This is why I find it so confusing...In some cases the Owner's manual says the sensor is to detect rain, and in others, the sensor is for LKA. Maybe it's both?

I'm not sure about the LKA sensor. It's the big honker on the windshield of my Highlander.

The one on the windshield is the rain sensor. The other one is the homelink garage door sensor.
