Never mind. I was surprised to see you didn't have roof lights. After a little research, I see it's a 'California' thing. Nice truck!

Nice! I just ordered one very similar. Curious to see your 'sticker' if it's not too much trouble. Thanks

Not to mention their shin bones. If I leave mine in I'll be looking for a band aid soon. I love the tailgate.

You are correct. Hill Decent Control is for slow speed/off road. There is a switch for that and if you flip it above 25 mph or so there's a msg on the info display. Just curious what engine/drivetrain you are running.

I guess you could turn off Tow Haul. From the manual: Tow/Haul Mode Grade Braking is only enabled while the Tow/Haul Mode is selected and the vehicle is not in the Range Selection Mode. See Manual Mode 0 234. Tow/Haul Mode Grade Braking assists in maintaining desired vehicle speeds when driving on downhill grades by using the engine and transmission to slow the vehicle

Looks like there are lots if reasons: The climate control settings require the engine to be running to cool or heat the vehicle interior. The vehicle battery charge is low. The vehicle battery has recently been disconnected. Minimum vehicle speed has not been reached since the last Auto Stop. The accelerator pedal is pressed. The engine or transmission is not at the required operating temperature. The outside temperature is not in the required operating range. The vehicle is in any gear other than D (Drive). Tow/Haul Mode or other driver modes have been selected. The vehicle is on a steep hill or grade. The driver door has been opened or the driver seat belt has been unbuckled. The hood has been opened. The Auto Stop has reached the maximum allowed time.
