Automatic parking brake defective?

Automatic parking brake defective?
According to the owners manual, when the automatic parking brake is enabled, the brake will turn on automatically when the vehicle is placed in park and the ignition is turned off. Additionally, after the vehicle is started and placed in Drive, the parking brake will turn off when the accelerator is pressed. My parking brake will not turn on automatically. However, after turning on manually, it will disengage after starting and placing in Drive. Does anyone else have this issue?

Here is a copy from the manual:
■ Activating and deactivating the automatic parking brake feature
With the power mode is in ON, carry out the following steps to either activate or deactivate the automatic parking brake feature.
1. Put the transmission into (P.
2. Without depressing the brake pedal, press and release the parking brake switch.
u Check that the Parking Brake and Brake System indicator (red) has come on.
3. Press and hold the parking brake switch. When you hear a beeping sound, release the switch and within 3 seconds pull up and hold the switch again.
4. When you hear a sound indicating that the procedure is completed, release the switch.
u Two beeps indicates that the feature has been activated.
u One beep indicates that the feature has been deactivated.
u When you have completed activating the feature, the parking brake will remain applied after you turn off the engine.
u To confirm that the parking brake is applied, check if the Parking Brake and Brake System indicator (red) is on.
If you need to temporarily deactivate the feature for when putting your vehicle
through a conveyor type car wash, you can follow the procedure explained below.
1. Depress the brake pedal and bring the vehicle to a stop.
2. Set the power mode to VEHICLE OFF and then within 2 seconds pull up the parking brake switch.
u Activation and deactivation settings for the feature will not be affected.
u Before temporarily deactivating the feature, make sure to first turn off both
ACC with LSF and the automatic brake hold system.
u To confirm that the parking brake is applied, check if the Parking Brake and Brake System indicator (red) is on.
This is on page 489 of the manual and is probably easier to read there.
Hope this helps some.

I have not turned that feature on yet. I can give it a shot and see what it does.

When I tried to activate my auto parking brakes, I tried the steps described by the online PDF manual. However, it didn't work. I think there's a typo. I forgot what I did totmake it to work. I think when it say "pull and hold", it meant "push and hold" or via versa.
Btw, my parking brake disengages automatically when I press on the gas. It should be by default.

Auto parking brake is something I'll never use. Living where I do having it freeze up in the winter is a very real possibility and I want to insure the only time it engages is when I specifically do it.

The odd thing that I noticed about the parking brake is that it uses the same switch as the TLX but, the functionality is opposite.
In the TLX, you pull to set and push to release whereas in the RDX, you push to set and pull to release.
Took me a while to get used to it.
Maybe whoever wrote the instructions for activating he Auto function got confused as well. Try reversing push and pull?

Interesting and haven't tried this yet. The push button, for safety reasons, should be set up to PUSH for RELEASE and PULL for BRAKE. It can be very dangerous if the button gets pushed while driving and I have never seen a car operate where PUSH is BRAKE???

It took me forever to figure out how to activate the auto parking brake. If you follow the steps listed above, in step 3 you need to push and hold until you hear a beep, then pull the parking brake button then PUSH and hold the button again. The instructions make it seem like you need to pull and hold.

"3. Press and hold the parking brake switch. When you hear a beeping sound, release the switch and within 3 seconds **push** and hold the switch again."

Electronic parking brake...... what a concept. I just hope it doesn't malfunction and engage when one is driving at highway speed. But then again, it's a "smart" car so when it wipes out and does a 180, the whole spectacle will automatically be posted on youtube and go viral.... I'll take a regular hand pulled (or less desirable pedal-pressed) "emergency" brake over this nonsense any day. And give me a regular shifter handle on the side please.

We have 2 BMWs and they both have electronic parking brakes. You have to set them but when you put the car in gear and press on the accelerator the brake releases. This works well and my wife has not said to me as we are leaving the driveway, "The brake is still on", even once. Well worth it.

I don’t use it at all, because it still puts pressure on the parking pawl.
Unless the spot is totally flat, like Florida flat, and the car doesn’t roll if left in neutral with the footbrake off, applying the brake after the car is put in park puts pressure on the pawl.
Since my driveway has a slope, when I park in the driveway, my sequence is, apply foot brake, put car in neutral, apply parking brake, release foot brake, when car settles, put it in Park. When starting off, apply foot brake, put car in reverse, release parking brake, move.
When the car goes in the garage, where it is level, I just put it in park. No pressure on the pawl.

The only downside I see to the electronic parking brake is the battery draw. Whatever that might be; I don't know.

Parking brake on the RDX also releases once you press the accelerator- as long as your seat belt is on. It’s pretty convenient having the parking brake automatically engage and release. At this point, when I park I just turn the car off and it shifts into park and engages the parking brake- all with the press of one button.

whats what I do, I just stop hit the button to turn the car off and it parks the tranny and parking brake enables, when I get in to leave I start the car, go to drive and give it gas and it disables for me, so easy

Madd Dog's way is the best way to set/release brake when there is an incline in my opinion. I tried a few different ways with and without the automatic brake and the way Madd Dog describes above has no clunks (can you say wear and tear?) from the incline. I am adopting this approach.
My order of operation for driving is putting car in gear > release parking brake > disable auto start/stop
