When the ABS pump fails, the vehicle may exhibit the following symptoms: 1. Inability to prevent wheel lock-up during emergency braking, posing a safety hazard; 2. The ABS warning light will illuminate, and the brake pads may fail to reset. The causes of ABS pump failure include: 1. Faulty ABS wheel speed sensor; 2. ABS wiring connection issues; 3. ABS control unit programming errors; 4. ABS master cylinder malfunction. The functions of ABS are: 1. Maximizing braking efficiency, reducing braking time and distance; 2. Effectively preventing vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; 3. Allowing steering during emergency braking, maintaining good steering control; 4. Avoiding excessive friction between tires and the road surface, reducing tire wear.

Can China 5 Vehicles Still Be Licensed After the Implementation of China 6 Emission Standards?

When the China 6 standard is implemented in a local city, China 5 vehicles will no longer be eligible for licensing. If you wish to purchase a China 5 vehicle, verify with the local vehicle management department before making a decision. However, already licensed China 5 vehicles will not be affected in terms of operation. Below is more information about China 6: 1. The China 6 standard was implemented in some major cities on July 1, 2019. After implementation, only vehicles meeting the China 6 emission standard can be licensed. All vehicles sold and registered must comply with the China 6 emission standard requirements. Vehicles below this standard will be prohibited from sale, registration, and transfer. China 4 and China 5 emission vehicles can only be scrapped or relocated to regions where the China 6 standard has not yet been implemented. 2. The China 6 emission standard is implemented in two phases: China 6A and China 6B. China 6A: Starting from July 1, 2020, all vehicles sold and registered must comply with the China 6A standard. China 6B: Starting from July 1, 2023, all vehicles sold and registered must comply with the China 6B standard.

Should You Use D Gear or S Gear When Going Downhill?

When going downhill, it is most appropriate to use D gear because S gear is the sport mode, which provides better vehicle power and is suitable for uphill driving and overtaking. For automatic transmission vehicles or vehicles with manual-automatic transmission, the following points should be noted when going downhill for a long distance: 1. First, when going downhill, vehicles with manual-automatic transmission must not shift to N gear, as this can damage the transmission. Additionally, speed control becomes difficult, which can easily cause the brake pads to overheat and lead to loss of vehicle speed control. 2. For long downhill slopes with moderate gradients but long distances, first switch the vehicle to manual mode, then adjust to 3rd gear in manual mode, and use engine braking in combination with the brakes. For steeper long downhill slopes, switch the vehicle to manual mode, then adjust to 1st gear in manual mode, and use engine braking with the brakes. Some vehicles are equipped with an L (low) gear, which allows the transmission to be set to low gear for downhill driving.

What are the body dimensions of the Mercedes-Benz GLK?

The body dimensions of the Mercedes-Benz GLK are length 4556mm, width 1840mm, height 1689mm, with a wheelbase of 2755mm. Below is an introduction to the Mercedes-Benz GLK: 1. The Mercedes-Benz GLK is a mid-size SUV that has been localized for production. The large-sized front grille of the GLK is identical to that of the Mercedes-Benz C-Class Fashion model, conveying the family characteristics of the new generation of Mercedes-Benz models. 2. The domestic version of the model uses two engines, one is a 2.0-liter turbocharged engine, and the other is a 3.0-liter naturally aspirated engine. 3. The 2.0-liter turbocharged engine delivers 211 horsepower and a maximum torque of 350 Nm, with the maximum power achieved at 5500 rpm and the maximum torque available between 1200 to 4000 rpm. 4. The 3.0-liter naturally aspirated engine produces 245 horsepower and a maximum torque of 300 Nm, with the maximum power achieved at 6200 rpm and the maximum torque available between 2500 to 5000 rpm.

How many subjects are required for the driving test?

The driving test consists of four subjects. The content and passing standards of the test subjects are uniformly regulated nationwide, and the test sequence follows Subject 1, Subject 2, Subject 3, and Subject 4 in order. Only after passing the previous subject can one proceed to the next. The details are as follows: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. The structure and basic question types of the test question bank are formulated by the Ministry of Public Security, while provincial traffic management departments under the public security authorities establish the test question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject 2: Field driving skills test, including test items such as reversing into a garage, stopping and starting on a slope, turning at a right angle, driving along a curve, and parallel parking. 3. Subject 3: Road driving skills test, including basic test items such as preparation before driving (walking around the vehicle counterclockwise, fastening the seatbelt, turning on the left turn signal, shifting gears, releasing the handbrake, and honking), starting, driving straight, changing lanes, passing through intersections, parking by the roadside, crossing pedestrian crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and driving at night. 4. Subject 4: Safe and civilized driving knowledge, covering test items related to safe and civilized driving.

What to Use for Cleaning Car Interiors?

When cleaning by yourself, pay attention to selecting different cleaning agents and auxiliary tools according to different parts. The specific contents of car interior cleaning are as follows: Cleaning the car center console: Use cleaning soft gel. For hard-to-reach gaps, cleaning gel can solve this problem. Cleaning door interiors: Cleaning liquid and towel. The cleaning agent can dissolve dirt on the door, and then wipe it off with a towel, which works quite well. Cleaning the car ceiling interior: Cleaning agent and brush. Spray the cleaning agent, then scrub with a brush, and finally wipe off the water with a towel. Steering wheel cleaning: Cleaning foam and towel. Since the steering wheel is made of leather, using foam cleaning can avoid damaging the leather material, with good results. Leather seat cleaning: Cleaning foam and towel. Seats are the most frequently used areas, so foam cleaning allows for deeper cleaning and is also easier to wipe off. Cleaning dust and debris inside the car: Car vacuum cleaner. The vacuum can quickly and effectively suck away debris from corners or gaps, especially fine sand and mud brought in by shoes, which is very effective.

What is the correct way to use an exhaust brake?

An exhaust brake (commonly known as an exhaust retarder) is a type of auxiliary braking device that functions as a secondary brake. Its purpose is to reduce or maintain vehicle speed without or with minimal use of the service brakes, although it cannot bring the vehicle to an emergency stop. Proper use of the exhaust brake can significantly reduce reliance on service brakes, thereby minimizing wear on brake pads (or discs) and greatly lowering the risk of overheating due to continuous braking, which could compromise driving safety. Key considerations for using an exhaust brake are as follows: 1. It is an auxiliary brake: The exhaust brake serves as a supplementary braking mechanism and cannot replace the service brake for emergency stops or be used as a parking brake. However, it can be used in conjunction with the service brake. 2. Preventing engine stalling when stopping: When the exhaust brake is engaged, the throttle pedal should be at zero position, and the fuel injectors stop injecting fuel. If the accelerator or clutch pedal is pressed, the exhaust brake will automatically disengage, preventing engine stalling when stopping and avoiding exhaust brake activation during fuel injection. 3. Engine exhaust braking power depends on engine speed: For optimal braking performance, when using the exhaust brake on long downhill slopes, select an appropriate gear (the transmission should not be in neutral) to keep the engine speed between 1600-2400 rpm. At lower engine speeds, the braking effect is limited, and it is advisable to shift to a lower gear or use conventional service brakes.
