Parking brake

[Ryom]

I tried on several steep streets to get it to engage automatically on a 24. But just last week on 2 different occasions it DID engage automatically will I shifted to P on a sloped area.

I have a 2025 Hybrid and the parking area in my driveway has a minor downward slope... the parking brake engages automatically most times for me. If this is a desired function for you I wonder if your service station could adjust the sensitivity somehow?

There is an easy way to test if the calibration on the accelerometer sensor is correct.

Notice a barely there slope where the Hill Assist does engage to give you that 3 seconds before brake release.

Turn truck around - still an assist going the other direction?

Because if the calibration is off - it'll sense enough slope pointing nose down say to provide it going in reverse, but not nose up in drive.
If it does it both directions - calibration should be good enough if the EPB is going to be auto-engaged.

Or use Forscan Lite. Confirm level is level.

WARNING: Apply the parking brake, shift into park (P),

We were taught that, after driving around the dinosaur, we were to fully engage the parking brake before shifting to park, so that the brakes, rather than the transmission, would bear the weight.

Hey all, my wife and I took her maverick on a recent road trip.we stopped at a dollar general and when she got back in she put her purse between the seats. I put the truck in reverse to back out of our parking spot and it wasn't moving. Before I realized what happened, she moved her purse and the truck started backing up before I realized it. Thinking I was still stopped I could have backed into something. Just a heads up....

When the parking brake is on, if you bump the throttle, it will release the parking brake, but there is a delay. So if you blip the throttle and it doesn’t initially move, then drops back to an idle, then starts to creep because it shut off the P brake, it is operating normally and working as intended.

it does this regardless of a purse having been in the general vicinity of the parking brake, and at some time point potentially before or after the P brake released because of throttle application.

Was your last new car a decade or more ago? This has been SOP for at least a decade.

Yes, I keep my vehicles a long time. Two are 16 years old, and I also have one that is 54 years old.

Ok. It’s most likely because you’re not used to electronic parking brakes.

The electronic parking brake can automatically set itself. It is programmed to self deploy if you park on a slope, if you shut it off while it is still in Drive, if you shift to park with inadequate pressure on the brake pedal, and a few other circumstances that I haven’t yet figured out.

So you stop, get out, go do your errands, come back, put car in gear and it won’t go….. it’s because it automatically set the parking brake because it sensed that you parked on a slope. But then sensing the throttle input, it knows that you want to go, so just like how it automatically deployed the parking brake, it automatically turns it off.

And a second or two after the throttle input, the car will start to creep, because it is in gear and the brakes are off.

this automatically setting parking brake is so backwards from the automatically releasing brake I'm used to from my Cadillacs! [vacuum line releases when put into gear]

And I still sometimes find myself shifting into reverse with a column shifted automatic by going forward three, then back two, as my '89 Crown Victoria would release in forward gears, but not reverse (avoiding cadillac patents? )

And yesterday, I was in a '59 Eldorado Biarritz (yes, reallY!), which didn't have the automatic release, but did have a little pedal attached to the parking brake pedal to release it.
