Is Auto Stop/Start Temperature Sensitive?

[MightyMaverick]

I was just wondering if the auto stop/start system is temperature sensitive because I've noticed that it never engages when it's scorching hot outside. However, when the temperature is a lot cooler, it engages at almost every stop, depending how deep I engage the brake pedal. It makes sense considering that when the engine deactivates, the air conditioning doesn't work as efficiently. It's strained by the lack of engine power. I'm guessing the computer senses how hot it is and purposely doesn't activate auto start/stop so the air works to its fullest. Does anyone else have any insight?

No. But it is battery sensitive . running ac fan draws enough to deactivate the auto start/ stop . more electric draw less start/stop .

Cut the ac off for a day or two and see if that helps.
You’re in the South so it makes it more fun.

With the A/C on and temps over 100 the autostop is de-activted.

If your cabin temp isn't in range of the set temp, the engine will not stop

And if you set it to LO or HI it won't stop either.

From the Maverick service manual. I am paraphrasing here.

During normal operation the auto start stop system may not stop the engine under the following conditions:

The A/C, heat or defrost settings are ON
The battery has a low state of charge or is below approximately 5°C (41°F) or above 60°C (140°F)
The maximum engine off time is exceeded
The engine operating temperature is less than 60°C (140°F)
The gear selector is in the PARK, REVERSE, NEUTRAL or SECOND GEAR position
Initial vehicle speed of greater than 4 km/h (2.5 MPH) and less than 2 seconds has elapsed
The vehicle is on a steep road grade
Elevation is above 12,000 feet (3,657 meters) approximately
The CPP sensor indicates the clutch pedal is not fully released
