How to Activate the Leiling Active Braking System?

[LaGemma]

Leiling's active braking system is automatically enabled by default. It can be accessed via the multifunction buttons on the left side of the steering wheel. The active braking has certain conditions—it must be directly in front of the vehicle, and sudden lane-cutting by other vehicles may not trigger it. However, in practical use, it is highly effective in preventing accidents caused by driver distraction on highways. The working principle of the active braking system is as follows: 1. Accident Prevention: The system uses an optical radar system mounted on the front windshield to monitor the road ahead, particularly within six meters. Upon detecting obstacles, it initiates steering adjustments or braking to prevent accidents. However, current technology is not yet fully mature, and numerous test cases indicate that it may not always succeed in bringing the vehicle to a complete stop under certain conditions. Nevertheless, as an auxiliary system, it effectively alerts drivers to pay attention to road conditions ahead. 2. Autonomous Driving Function: The new Leiling achieves Level 2 autonomous driving capabilities through the integration of DRCC, PCS, and LTA systems, making driving safer and more relaxed. The PCS pre-collision system can accurately identify vehicles, pedestrians, and cyclists moving at speeds exceeding 10 km/h during daytime. In emergencies such as sudden pedestrian intrusion, unexpected road hazards on highways, or situations where braking is delayed, the system will sound an alarm and automatically bring the vehicle to a stable stop, minimizing the risk of collisions.

I also wondered about this when I first got my car. The Corolla's pre-collision system is actually enabled by default, but it's best to double-check. After starting the vehicle, use the buttons on the right side of the steering wheel to navigate to the instrument cluster menu - the little gear icon is the settings interface. Scroll down to the 'PCS Pre-Collision System' option and make sure it shows 'ON'. You can adjust sensitivity across three levels - I recommend setting it to maximum for city driving. Last week on the expressway, I almost rear-ended the car ahead when the system suddenly braked hard with an audible 'clunk' while flashing red warnings on the dashboard - it literally saved me that time. Just remember to regularly clean the windshield camera area - snow or dirt can interfere with detection. No matter how good the safety systems are, you still need to stay vigilant yourself.

I've looked into this quite a few times. The Leiling's automatic emergency braking is part of the TSS (Toyota Safety Sense) system, which doesn't require manually activating any switch—it automatically engages when the vehicle is powered on. If you see a green car icon light up on the dashboard while driving, it means the system is functioning normally. However, if you want to adjust the settings, you'll need to do it through the central control screen: go to the home page, enter vehicle settings, select the pre-collision system under safety options, where you can toggle the function on/off or adjust sensitivity. Real-world testing shows it's most responsive to stationary objects at speeds above 40km/h, with slightly reduced recognition at night. Once during heavy rain, it detected a food-delivery electric bike crossing the road half a second before I did and initiated braking, which gave me quite a scare. I recommend having technicians check the radar module with a diagnostic tool during every maintenance service.

It's as easy as three steps. First, start the car to light up the dashboard, then use the up and down buttons on the right side of the steering wheel to find the settings menu. When you see the gear-like icon, click into it and select the PCS (Pre-Collision System) option in the second row. Just make sure it shows as enabled—no need to manually turn it on every time. When my wife first got her driver's license, she was always worried about braking too hard. Actually, as long as you pay attention to three things while driving, you won't trigger it by mistake: don't get too close to the car in front, don't brake too abruptly, and keep both hands on the steering wheel. Last month, when I was picking up my kid from school, a teenager on a skateboard suddenly rushed out at an intersection. Before I could even react, the system slammed on the brakes, stopping the car just three meters away from the kid. Developing the habit of glancing at the green car indicator light before driving is definitely a good idea.

As a long-time Toyota owner, I'm quite familiar with this feature. The automatic braking system requires no additional operation – it's on standby as soon as you start the engine. For fine-tuning, you need to access the vehicle computer settings: keep steering under 30 degrees while driving straight and press the OK button on the steering wheel to enter the menu. Look for the 'Safety Settings' section marked with an exclamation point icon – the third option is the collision prediction switch. Let me emphasize its practicality – the system is most sensitive between 10-80 km/h, with about 20% higher recognition rate for vehicles compared to pedestrians. Last week on the highway during foggy conditions, when the truck ahead braked suddenly, the warning alarm and braking activated simultaneously, and the seatbelt tightened with more force than my driving instructor ever did. Remember not to directly spray high-pressure water at the millimeter-wave radar located below the front license plate when washing the car.

Tried this feature right after getting the new car. No need to manually activate it after keyless startup—just shift to D gear and hit the road. To check the status, press the right directional button on the steering wheel to access the settings page, then select the radar-wave icon to enter the PCS menu. Once enabled, a green car icon will stay lit on the instrument panel. Real-world tests show the system reacts fastest below 50km/h, responding within 0.5 seconds. Some friends reported false triggers, so it’s advised to manually downshift and decelerate in traffic jams to avoid sudden braking. Once on the highway, I almost hit a stalled car due to drowsiness—the automatic braking kicked in with a sharp alarm and seatbelt jerk, scaring off all sleepiness. After rain, remember to gently wipe the monocular camera above the center of the windshield with a soft cloth.
