As above.

I seldom drive my car and wash my car quite frequently. Had a few incident of electronics brake engage when I drove off, was wondering is there a method to stop the electronic parking brake from engaging when parked ??

You can manually pull the parking brake handle after parking. The brake is supposed to release when you drive off if your door is closed and seatbelt fastened.

I would like to park and lock my car without activating the electronic brake, since I park at levelled grounds.

Not sure why it's a big deal. Just manually release the brake when you drive off if it does not automatically. Using the parking brake is advised even on level ground. But, you can also pull the parking brake lever after parking to cancel the auto brake set.

NEVER used the parking brake, just leave in park

Per the manual, it automatically engages and disengages in most conditions.

Yes, that's why I'm trying to figure out how NOT to auto engage

It will always auto engage and as far as I know it can't be disabled. It's a safety mechanism that's becoming pretty much standard in cars with electronic gear selectors, because of recent incidents of people getting out of their car not realizing it wasn't in Park. The most notable one is Anton Yelchin who got crushed by his own car, because he got out of it and forgot to put it in Park, and then the car rolled down and crushed him against a wall. So, the parking brake will engage when you open the driver's door if not earlier. On the latest models it engages as soon as you turn off the engine, but if you get out of the car with a running engine it will engage as soon as you open the door. There's no way around it. Just curious, what difference does it make? It does relieve stress on the parking pawl of the transmission. However, it is advised to manually release the parking brake if you park the car with wet brakes to avoid the pads seizing to the rotors, but that can generally be avoided by going for a quick drive after washing the car etc. At the AMG Driving Academy we were specifically instructed to release the parking brake when getting out of the car, as not to cause uneven brake pad deposits due to the hot brakes, but this is not something you'll have to worry about with normal daily driving.

Yes, I have finally manage to figure out how to manually release the brakes after a few tries.

I'm trying to avoid brake locked after wash.

You should always go for a quick drive after a wash and use the brakes so they dry off. The brake pads are always in contact with the rotors, there just isn't any pressure applied to them, but that's enough for them to still seize if they are left wet. Brake dust contains fine metal dust, which starts to oxidize pretty much immediately.

Good Grief, that's what's making that horrible sound! My pads are gluing themselves to the rotors! (2024 GLC300 3,000 miles) I go through the car wash, drive 4 miles home.

The next morning, I put the car in gear to leave the driveway. I have to put a little extra pressure on the accelerator to get the car to move, and then there's this loud BANG! sound emanating from the brakes. If my wife's in the car, she jumps.

Since I go through the car wash 3 times a week, this brakes-stuck-to-rotor phenomena really makes me nervous that an entire brake job will be needed before the car gets to 10,000 miles!

It's sad Mercedes doesn't trust us to turn this off. I never park on hills. (No hills in Chicago anyway). No way I'm going to do a 1930's routine of manually making my car ready for sitting in the driveway overnight, LOL. Oh well. Forum and Google searches continue...looking for a way to turn "nanny" thing off!

Here's the sequence:
While the engine is running, open your door. The Parking brake will set.
Before you turn the ignition off, disengage the brake, then turn the ignition off.

Usually after the rotors get wet just a few brake applications will dry them enough to keep that from happening.

How long are you letting your car sit for? I never drive my car right after a wash. I let it sit over night at the very least. So I'm not sure why your brakes would be locked

mikapen

Pads rusted to the disc.

GregW / Oregon

Driving right away is best way to dry the rotors off.

Benzman33

They shouldn't that fast?

Benzman33

It's also the best way to get your clean car dirty again.

mikapen

Don't you just hate it?

If by that you mean brake dust, ceramic coating the wheels at least the wheels stay clean : )

As an option, try a product like this one. My boys gifted this to me several years ago and it works quite well. Paint, glass, wheels. The warm, forced air doesn't discriminate, it does the job.

superswiss

^^ There's also a smaller one. I have this one to blow the water out of the nooks and crannies. Haven't used it in a while, though as I got tired of hand washing my car, but it works great to dry all the areas where the water hides and then just runs down the paint and leaves water marks. It's very powerful, but also kinda loud. Key is it filters the air instead of blasting all the particles in the air against the car's paint. Definitely a good option. To be honest I kinda forgot that I had this, so I might start using it again after a touchless wash.

It doesn't take much. Overnight is plenty of time. You'll get it after a wash or rain. Makes my wife jump as well. Whatever pad material they use seems to exaggerate the issue in comparison to my other vehicles. Likely a change in pad material would reduce the issue.

Benzman33

That doesn't work, just easier to clean. My Porsche had layers of professorial ceramic coating done to it. Was always dirty. It washed off super easy and was super super clean when it was clean haha

I see, then at least it makes it easier to clean : )
