Fresh Air ciruculation mode actively cools the hybrid batteries!

FYI. In Fresh Air mode, what goes in must go out.

Setting your car in Fresh Air Mode (not recycled) will allow fresh air into the cabin and all that same air out through the hybrid fan system and channel all that air out through the hybrid battery modules to cool them down without using the hybrid fan system. How do you know if this is working? Have someone from inside the car turn the cabin fan on at full blast and in Fresh Air mode with all windows closed. Then go to the rear bumper passenger side (since that is where the hybrid battery air exhaust is located). Place your hand under the bumper and if you feel a blast of air coming out from under the bumper then your Fresh Air mode is actively cooling your hybrid battery modules without even running the hybrid fan system. This is all using cabin air fan system. All that air that goes into the cabin must go out through the exhaust outlets. If you have a good blast of air coming out, then I would say you have a good air flow going through your hybrid battery modules and actively cooling the hybrid batteries in the process. Which could mean longer hybrid battery life!!! If you don't feel a strong blast of air, there could be obstruction somewhere!! Thus a good time to consider cleaning the entire fan and air flow of the outlet vents and check if the cabin air filter needs to be cleaned or replaced. Obstruction in the cabin air filter means less air going out!

The outlets are on both sides under the right and left bumper. But the passenger side bumper is where the hybrid battery is and it should have the strongest air flow.

Just putting your hand under the right or left bumper you will feel the air flow coming out of the cabin. When doing this test, make sure all windows are closed. Safer to do this with 2 person. And don't activate the ready mode. Don't press the brake. Just hit the Power button twice to just activate the 12v mode just to run the fan for testing. If you need to do this with one person, detach the key from the remote and keep the door key with you.

 

Oh I didn't check for that and good to know.
