You should see a red "park" illuminated on the top part of your dashboard if parking brake is engaged. I think the system should prevent that above certain speed? Otherwise you can drift your XC90.

Parking brake is released when car starts moving. Just try it from standstill you should see it happen.

 

More importantly, how about he / she just stops flipping on the parking brake while the car is being driven?

 

That would be great!

My parents would've slapped me over the head and then kicked me out of the car if I did that when I was younger.

I'd slap him too if I were driving

I really want to know why she was flipping it on... Just curious.

Teen being a teen

Yes, you actually have to hold the parking brake up for it to apply while moving and as soon as you release it, it stops applying. She'd know if it was applied as well, it's pretty loud and you can feel the rear wheels grab.

Supposedly the car lurched. I wasn't around.

As it was rolling down the road, yup mine too!

 

Well as advised from the s60 manual moons ago, you risk reduced tire life, potential loss of control of vechical, and / or brake life, if used while in motion.

 

In the XC90 manual it says that you have to pull it and hold it to use it as an emergency brake, so doesn't do anything if you just flip it while driving (as expected, being a switch)

Perhaps disbelief when friends told her about electronic e-brake switches and trying to see if there's still a hope

 

As a car guy I'd have to say I'd sort of be proud of my kid for trying handbrake turns (if in fact that's what she was doing). I'd also be pissed for doing so on the wrong type of car...high profile, rollover risk, etc.

Pulling the parking brake on the XC90 actuates the rear brake calipers. So from a damage perspective it's akin to slamming on the rear brakes only. Hard on pads/rotors and rear suspension, flat spot the rear tires, etc are the results. My main concern would be rollover risk or hitting something if they get sideways with the rears locked up.

Mom was driving, kid playing with the controls.

Why do kids drink/smoke even when they're not "supposed to"? Just being kids ;-) (and mom not being very attentive)

 

I have a 2 year old that plays with the buttons. I’m hoping that by the time he is 16, we have moved beyond this

Yeah I would hope so too! Well he'll have a license in a couple months, after that he's on his own! (LOL)

 

To reflect the others, I don’t know if it’s not good for the car, but I can say from experience that it is dangerous and quite frightening and I wouldn’t recommend it if there isn’t an emergency.

I accidentally pulled up the electronic handbrake on our ‘17 XC90 while doing 70mph on a Vermont highway. I was trying to get my sunglasses out of the center console storage bin and the ebrake handle felt quite a lot like the latch release on the cubby. I dropped from 70 to 35 in no time flat amidst chirping tires and a stream of cursing. I immediately realized what I had done, pressed down on the brake to release and floored it so I wouldn’t get rear ended if someone had been behind me. Luckily there wasn’t and I was on a straight section of road so all was okay.

However, I am now always extra careful when trying to use the storage bin at speed. I actually think that this is a flaw in the design that Volvo could remedy. But then, maybe I’m the only idiot who is stupid enough to have done this.

 

I accidentally hit it while looking for something in the arm rest while driving ... nothing about what happens when it's activated feels natural in a car while moving, although it only applied the brake for a fraction of a second I was on dry roads and it felt like I ripped the back axle right out the back of the car, I was in a T8, a T6 would be worse as the whole drive-line from rear axle, driveshaft and transmission, all would suddenly and momentarily stop, causing allot of torque on the system, You couldn't devise a more damaging torture test for a car then doing that repeatedly in an all wheel drive situation.

Front wheel drive is fine as the rear wheels are spinning freely with no drive components connected to them.

Are they trying to replicate a manual handbrake skid.? If that's the case it's a lost cause , even though it might work momentarily the parking brake is controlled by an electric motors that will eventually fail if abused like that, the old style hand brake was just a simple cable setup that manually clamped the brakes, trying to throw a car into a skid with an electric handbrake is pointless and eventually expensive.

Just a thought is he/she thinking its the button to put it into park.?

Hmmm- think of this forum as a sample of the general population of Volvo owners. If just 2 out of perhaps 1000 owners of this car (who are forum members) have experienced this (0.2 %) then there must be hundreds of other unreported incidents 'out in the wild' so yes this is a horrible and dangerous design feature. Just rough math but you get the idea.

 

I doubt it. I thinks it's just lack of attention on the drivers part. The majority of new cars on the market have the parking brake switch in the exact same location and I've never heard of an issue like this until this thread... You'd be more likely to accidentally activate the floor mounted parking brake in the P2 XC90.
