I would like to hear from members here who have experienced the PCS in action so I know what to expect if it ever activates when I'm driving.

The PKSB (Parking Support Brake) has left me anxious and paranoid now about the smart features my car has, ever since I was injured by it last week.

When the PCS kicked in for you, what happened exactly? I assume at the very least your brakes were applied?
How fast were you going approximately? How close were you to the vehicle in front of you?
Were the brakes applied slowly, or violently?
Were you injured in any way as a result of the brakes being applied?

 

Usually happens when I am at a heavy traffic and people slam their brakes.
I have never been injured as a result of automatic brakes applied.
One time I was braking and the system helped me brake even further.

 

My car activates it very often. First it beeps very loudly and after a half a second slams the brakes hard.

It helped me many many times

 

What I also like about this system is, it shows huge warning on the 12.3inch display, cuts the radio/Android Auto, Apple car play and it beeps.
It did save me hitting the car ahead many times. When it thinks you are accelerating more than you should and you are more likely to hit the object ahead of you, it warns and sometimes it engages the brakes.

 

The first two times I experienced it was when I took my F Sport to a hand wash and a guy was telling me how far to back into a spot for them to dry, vacuum, etc… It stopped pretty violently, or maybe I wasn’t expecting it, when I was too close to him.

It also happened last week when someone stopped suddenly in front of me. I was already braking and felt it braking too. Now that I’ve experienced the system I actually like it.

 

Thanks for your reply FastDawg.
I think you are mixing up two different features?
The PCS is a front camera/radar system.
A different camera/braking system is used when brakes are applied when you back up.

But it's interesting to hear about both of your experiences.
My brakes were also applied quite violently when I was backing up last week.
Do you remember if you had your foot on the brake when it happened or was it on the accelerator?

 

I didn't realize it was two different systems. In the backing situations my foot was lightly on the accelerator. In the situation where someone stopped suddenly in front of me I was already braking.

 

That could have made a difference. My foot was on the brake pedal.

 

Yeah, same. Will be disabling this too. There are too many damn acronyms. I used an AI to summarize the pdf manual and make a summary. Hope it's useful for someone else:

1. PCS (Pre-Collision System) - (Pages 169, 181, 191, 353, 410)
   • A safety system designed to detect potential collisions with vehicles or pedestrians and provide warnings or automatic braking to help avoid or mitigate impacts. It can be customized for sensitivity and activation settings.
2. PKSB (Parking Support Brake) - (Pages 232, 236, 241)
   • Assists in preventing collisions during parking by detecting obstacles around the vehicle and automatically applying braking force if a collision is imminent. It enhances safety in low-speed parking scenarios.
3. BSM (Blind Spot Monitor) - (Pages 206, 411, 452)
   • Monitors blind spots on either side of the vehicle, alerting the driver with visual or audible signals when vehicles are detected in adjacent lanes, enhancing safety during lane changes.
4. RCTA (Rear Cross Traffic Alert) - (Pages 206, 352)
   • Works with the Blind Spot Monitor to detect vehicles approaching from the sides when reversing, providing warnings to prevent collisions during backing up.
5. ABS (Anti-lock Brake System) - (Page 191)
   • Prevents wheel lock-up during sudden braking, maintaining steering control by modulating brake pressure, improving safety on slippery surfaces.
6. VSC (Vehicle Stability Control) - (Page 191)
   • Helps maintain vehicle stability during cornering or on slippery surfaces by automatically adjusting engine power and brake force to prevent skids.
7. TRAC (Traction Control) - (Page 191)
   • Reduces wheel spin during acceleration on low-traction surfaces by controlling engine output and applying brakes to specific wheels, enhancing grip.
8. LTA (Lane Tracing Assist) - (Pages 181, 189)
   • Assists in keeping the vehicle centered in its lane by providing steering support, especially during highway driving with adaptive cruise control.
9. RSA (Road Sign Assist) - (Page 193)
   • Recognizes certain road signs (e.g., speed limits) using cameras and displays them on the vehicle's multi-information display to inform the driver.
10. AHB (Automatic High Beam) - (Pages 156, 159, 360)
    • Automatically switches between high and low beams based on surrounding traffic conditions to optimize visibility without dazzling other drivers.

These systems are part of the vehicle's advanced safety and driving support features, customizable through the car's settings to enhance driver safety and convenience. For detailed customization options, refer to the "Customization" section (Pages 404–415).

 

Why are you disabling it?
Just because it engaged a few times and you didn't like it doesn't mean you should permanently disable it.
That one time it engages in the future could save you or someone or can save you from a bumper collision repair bill.

 

Thanks,
Great to keep.

 

His choice - it's a great safety feature IMO despite the occasional annoying false alarm.

 

To each his own.
If you were injured by the system less than one week after buying your vehicle (as I did) you might have a different take on this.
Miraculously I drove multiple vehicles for 50+ years without this feature and never had any issues.

 

We all managed years ago without the latest technology. So to not take advantage of it now seems ridiculous but you're right, do what's best for you but don't criticize a safety feature that most people benefit from. Anyone want to give up HDTV and get that 19" B&W antique sans remote

 

Agree, the feature is very useful, innovative, and could potentially prevent accidents. I definitely wouldn’t recommend disabling it permanently. Your HDTV analogy is very good.

That said, there are scenarios where the feature might actually introduce risk IMHO, especially when timing is critical. In those cases, a quick toggle would be extremely helpful.

I posted a video in another thread where holding the VSC for 3 seconds might temporarily disable the feature. I haven’t tested it myself yet, but if it works, and pressing it again reactivates it; it could serve as an excellent workaround.
