The manual is by no means easy to understand. Although I have not diagrammed the procedures, (having experience in real time computer process programming) it appears to me that when the manual states to not manually release the parking brake, there is an undisclosed reason, elsewhere maybe on this site and possibly on another Ford centered site I read that when the selector is placed in park, (assumed manually or electronically) the parking brake is set and the parking pawl is engaged (you will then have parking brake (aka emergency brake?) set to "hold" and parking pawl (designed to hold the planetary gear set from turning which can hold the car in place even though not designed to be the sole "holder". I have not been able to locate where the parking brake pawl/dog is located. It can be many places and just has to hold the wheels preferably without loading the headset. In one of John Kelley's videos he said the was a one way clutch (on or near the damper at the engine) that he did not know why it might be there but he suspected it might prevent engine from being turned backwards. I doubt since this is preventing reverse rotation and not forward that it has anything to do with park brake. Anyway back to subject of not releasing parking brake manually. Consider the possibility of releasing the parking brake manually and then NOT moving the dial OUT OF DRIVE, changing your mind and getting out WITHOUT manually resetting the parking brake and then only the parking pawl will be set. Perhaps the manual should have stated "Do not manually turn off the parking brake without before or after selecting a drive mode.???". Maybe there is another or additional reason. The original post is right on "why am I confused". Those doing their brake setting and releasing can continue but may or may not inadvertently set up a bad condition.

Yes, thank you, this is exactly the kind of handwringing and consternation I was talking about!

Fine, I'll play. We're talking about electronic control of two mechanical processes. The e-parking brake activates a mechanical process that physically clamps the rear brakes. The transmission dial activates a mechanical process to move the transmission between modes. If you're holding the brake pedal, the vehicle will remain stationary, so releasing the parking brake and/or putting the vehicle in gear (in any order) will put no more undue strain on the system than sitting at a stoplight.

My read between the lines logic for the owners' manual is, in the situation where the vehicle is parked on an incline, manually releasing the parking brake while the vehicle is in park could/would cause the vehicle to roll slightly and put undue stress on the transmission (or park pawl as you mention). They don't want you to do that.

Either way the resolution to this confusion is simple. Keep your foot on the brake and stop worrying.

Or sell your Maverick and take the bus!

You sure can use the electric parking brake in an emergency. See your manual.

Yes seen that not sure how that would work though.

I have been doing this all wrong according to the manual.

When I park, I usually stop, manually spin the dial to Park, even though I know the truck will do it for me when I turn it off. (I don't want to get into the habit of trusting the truck to do it as I drive other vehicles). Then I pull up to engage the parking brake, then I press the On/Off button in the Lariat.

When I start the truck, I push the brake release, spin the dial to D or R and then press the gas pedal.

All normal behaviors, and all wrong for my Maverick according to the manual which tells you not to manually release the parking brake while in Park.

So I tried a few odd behaviors to see what actually happens in different scenarios.

1. Open the door with the truck still on and in gear and your seatbelt connected, and your foot on the brake. Truck stays in selected gear but parking brake applies automatically.
2. Open the door with the truck still in gear with your seatbelt Disconnected, and your foot on the brake. Truck goes to PARK and parking brake applies automatically.
3. Press the On/Off button and truck goes into Park and applies the parking brake, motor turns off.
4. Start truck by pressing button and brake, let go of brake, put in gear. Truck keeps parking brake on unless you press gas pedal, then it automatically releases the parking brake as soon as you give it a little gas.

And I thought I knew how to drive.

In 55 years of driving I have never used my parking brake, even when I drove a stick I would put in first gear.

So according to this, I can't roll up to something on the road, open the door while still sitting in the seat in drive and pick it up and drive away? Sounds like the truck will automatically brake,and automatically put itself in park?

I personally don't release parking brake while in park I was only pointing out to those that insist on doing it why they might not want to do it!

Until the invention of these newfangled electronic parking brakes, I just used mine for e-brake turns on tight gravel roads or other silliness. I think I'll pass on trying that with an electronic e-brake.

So after reading all this its sounds like the ebrake goes on every time you put the car into park? Not sure about N though. I guess I have some experimenting to do when I pick mine up tomorrow.

first time with ebrake. Wish it had a cable. Only time in past car I would use cable brake was parking on incline. Stop on incline in D engage cable park brake put in N to see its holding, then put into park so I new all weight of car was being held by cable park brake.

But assuming it does always use ebrake no need for this? Sure wish it had a cable parking brake. More crap to break. I park on incline a lot at kayak launch sites. Many launch sites have incline.

I'm confused. I always release the parking brake manually in my 2022 XL Hybrid so I can drive off smoothly without the hesitation I can feel if I use the automatic release.

My 2022 Owners Manual does not have the warning you circled in red. I wonder what was the reason for the change.

Is this for automatic transmissions? We don't have them with the hybrid. We have a eCVT whatever that is.

Same here - even though I know the vehicle will do these things by itself, old habits die hard.

lol

Only one way to find out...

*Whispers in ear
Do it.

But seriously, no, that's only when stopped with your foot on the brake, in D, with your seat belt off. Once the seatbelt goes on and your foot comes off the brake, there is no automatic brake (unless it's the pre-collision ones). I think that is the sequence anyways.. or maybe it's with seatbelt on? Whatever...

You should be good to grab Alligators off the roads in Florida when rolling past them.

Always amazed by the number of people that don't use their parking brake. Many, many years ago I worked in a marina in SoCal, about once a month a vehicle would roll down the launch ramp when they were getting the boat on or off the trailer - we got pretty good at attaching airbags and floating it enough to pull it out.

Starting to sound like algebra now ha ha.and no alligators,but I have been known to pick up a stray bungee here and there!
