What Does the Hill Start Assist System Mean?

The Hill Start Assist System, abbreviated as HAC, is a function derived from the ESP system. It allows the vehicle to maintain braking for a few seconds after the right foot leaves the brake pedal when starting on a slope without using the handbrake. This enables the driver to easily shift their foot from the brake pedal to the accelerator pedal, preventing rollback and potential accidents, without causing panic. The steps to use the Hill Start Assist System are as follows: 1. Press the brake and clutch pedals firmly, ensuring the gear is in 1st position. If you press the clutch and brake first and then shift to 1st gear, the Hill Start Assist will not activate; 2. First, lightly press the brake, shift to 1st gear, release the clutch and brake slightly to let the car move forward a bit, and immediately press the clutch and brake fully to activate the Hill Start Assist; 3. When starting, after releasing the brake, the vehicle can remain stationary for 2-3 seconds, providing enough time to release the clutch and press the accelerator to move forward.

The hill start assist system is a little helper when we start driving on a slope. I remember two years ago when I was driving to a mountainous area for a trip, the car was parked on a steep slope. When I released the brake and prepared to step on the accelerator, the system automatically maintained the brake pressure for a few seconds, preventing the car from rolling backward. This gave me enough time to switch to the accelerator position without worrying about rolling back and hitting the car behind. Its principle is to detect the slope through sensors on the car and temporarily maintain the brake while you switch your foot. It's completely automatic and doesn't require pressing any buttons. Nowadays, many new cars have this feature, especially SUVs or hybrid models. It greatly reduces driving stress and the risk of accidents. Particularly for beginners or manual transmission drivers, it feels especially useful, eliminating the awkwardness and danger of starting on a slope. During regular maintenance, I also check if this system is functioning properly since it works based on the electronic brake system.

What Does On-Demand Four-Wheel Drive Mean?

On-demand four-wheel drive refers to a system that automatically activates four-wheel drive when the vehicle encounters conditions requiring it, otherwise operating in two-wheel drive mode. Automotive four-wheel drive systems are categorized into full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. On-demand four-wheel drive does not require driver intervention. When poor road conditions or wheel slippage are detected, the system automatically engages and redistributes engine torque to the front wheels, seamlessly switching to four-wheel drive. Compared to other four-wheel drive systems, on-demand four-wheel drive has a simpler structure, effectively reducing costs and overall vehicle weight. It is suitable for those needing moderate off-road capability while maintaining fuel efficiency. Precautions for using on-demand four-wheel drive systems: The vehicle will automatically switch from two-wheel drive to four-wheel drive when detecting wheel slippage, active steering, or loss of control. Alternatively, the driver can forcibly engage four-wheel drive via a lock switch, though this method has specific requirements. For example, in the Toyota Highlander, the four-wheel drive mode can only be maintained at speeds below 40 km/h after locking. Some part-time four-wheel drive vehicles cannot use four-wheel drive on hard surfaces, especially when turning, due to the lack of a center differential in the transfer case, which prevents adjustment of front and rear axle speeds.

What is the most effective way to clean a three-way catalytic converter?

The most effective method to clean a three-way catalytic converter is disassembly cleaning, although it is more labor-intensive and time-consuming. This process involves completely removing the three-way catalytic converter from the vehicle, soaking it in a cleaning agent (such as oxalic acid or toilet cleaner) for a period of time, and then rinsing it with clean water. The three-way catalytic converter is an important external purification device installed in the automobile exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted by vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The three-way catalytic reactor resembles a muffler, with its exterior made of double-layer stainless steel thin plates forming a cylindrical shape. Between the double-layer thin plates, there is an insulating material—asbestos fiber felt. Inside, a purifying agent is placed between the mesh partitions.

What to Do If a Novice Driver Loses 15 Points in One Day?

You can handle electronic monitoring violation records of 1, 2, or 3 points through the Traffic Management 12123 app, reducing the total points deducted to below 12. Others can wait until the probationary period of their driver's license is over to process the violations. If there is an electronic monitoring ticket that deducts 12 points at once, it also needs to wait until the probationary period is over to be processed. This way, the license will not be revoked, and you only need to retake the theory test (Subject 1). If it's just an electronic monitoring ticket, you can register the vehicle under a family member or friend's driver's license to handle part of the violations, and then use your own license to process the remaining violations. If a driver's license accumulates 12 or more points within a single scoring cycle, the driver must report to the traffic management department of the public security authority at the place where the license was issued or where the violation occurred within 15 days. They must attend a seven-day course on road traffic safety laws, regulations, and related knowledge. Notes on handling violations: One driver's license can only process violations for up to three vehicles, and one vehicle can only be processed by up to three driver's licenses. If a vehicle is recorded with a 12-point deduction at once, a probationary driver's license cannot be used to handle it. Instead, a license that has passed the probationary period can be used to assist in processing, avoiding license revocation. Tickets issued by traffic police on-site or those captured by high-definition cameras showing the driver's face cannot be processed using another person's driver's license; only the violator's own license can be used. This is because the traffic police department will conduct facial recognition to verify the identity of the violator.

Can I still drive if the low tire pressure warning light comes on?

If the low tire pressure warning light comes on, you should not continue driving. Immediately reduce your speed, avoid sharp steering and sudden braking, then stop to check the tires. When the tire pressure warning light illuminates, there are typically four possible causes: 1. The tire has been punctured; 2. The tire pressure is too high; 3. Driving with low tire pressure for an extended period; 4. A malfunction in the tire pressure sensor. If the tire pressure warning light comes on while driving, first turn off the engine, wait 1 to 2 minutes, then restart the vehicle. After the vehicle stabilizes, check the tire pressure values displayed on the dashboard. Both insufficient and excessive tire pressure can trigger the warning light. You can slowly drive to an auto repair shop or detailing shop to adjust the tire pressure. If you have a personal inflation device, you can adjust the pressure yourself.

How to Make a U-turn at Traffic Lights Intersection?

Making a U-turn at traffic lights intersection: 1. U-turns are allowed at intersections with U-turn signs; 2. U-turns are allowed at intersections without U-turn lights but with left-turn lights; 3. If there is no U-turn indicator or no U-turn prohibition sign at the intersection, vehicles can make a U-turn at any time without affecting other vehicles and ensuring safety; 4. U-turns are allowed in yellow grid areas. Parking is strictly prohibited in areas with yellow grid lines. When the traffic light ahead is red, vehicles behind should avoid stopping in this area, but as long as there is a central guardrail, U-turns are allowed in this area; 5. U-turns are prohibited in zebra crossing areas.
