What to Do If a Car Doesn't Have Tire Pressure Monitoring?

What documents are required for the driver's license medical examination?

Bring your ID card and a recent one-inch color photo with a white background. Some driving schools/DMV offices require students to take photos on-site. Below is relevant information: 1. The driving school medical examination is a relatively simple routine check that does not include blood tests. The most important aspects are checking vision, hearing, color blindness (red-green), and any disabilities. 2. The driver's license test is an examination to obtain a motor vehicle driver's license. The test content and passing standards are uniformly set nationwide. The test is divided into three subjects with four examinations: theoretical knowledge, field driving skills, road driving skills, and safe and civilized driving knowledge. The basic process of the driver's license test includes filling out forms, medical examination, acceptance, payment, examination, and certificate issuance.

What are the differences between C1, C2, C3, and C4 driver's licenses?

Below are the specific differences between C1, C2, C3, and C4 licenses: 1. In terms of permitted vehicle types: C1 allows driving small and micro passenger vehicles, as well as light and micro cargo vehicles; light, small, and micro special-purpose vehicles, and it also permits driving C2, C3, and C4 vehicle types. C2 allows driving small and micro automatic transmission passenger vehicles and light and micro automatic transmission cargo vehicles. C3 permits driving low-speed cargo vehicles (formerly four-wheel agricultural transport vehicles) and also allows driving C4 vehicle types. C4 permits driving three-wheeled vehicles (formerly three-wheel agricultural transport vehicles). 2. In terms of vehicle configuration during the test: C1 tests are conducted with manual transmission sedans, C2 tests with automatic transmission sedans, C3 tests with low-speed cargo vehicles, and C4 tests with three-wheeled vehicles.

What is the function of ABS?

ABS functions: Maximize the effectiveness of the brakes, shorten braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing excellent steering control. Avoid severe friction between tires and the ground, reducing tire wear. ABS working principle: During braking, ABS quickly determines wheel lock-up status based on speed signals from each wheel speed sensor, closing the normally open input solenoid valve for wheels beginning to lock to maintain braking force. If wheels continue to lock, the normally closed output solenoid valve opens, rapidly decreasing braking pressure on that wheel through the direct connection to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S at 20%), achieving the best braking effect and maximum driving safety.

What is the sequence for using the three differential locks?

The three differential locks must be engaged in a fixed sequence: 1-2-3, corresponding to center-rear-front differential locking in order. Below are the details: 1. Engage Differential Lock 1 (Center Differential Lock): Synchronizes the rotation speed of the front and rear axles, suitable for gravel roads, slightly uneven surfaces, or gentle slopes where single-wheel slippage (either front or rear) may occur. Not recommended for cross-axle situations. 2. Engage Differential Lock 2 (Rear Differential Lock): Synchronizes both rear wheels with the front axle's rotation speed, ideal for encountering large rocks or severely uneven terrain where only one rear wheel maintains traction. 3. Engage Differential Lock 3 (Front Differential Lock): Equalizes power distribution to all wheels, designed for extreme off-road conditions where wheels on one side completely lose traction or only any single wheel has grip. Suitable for desert driving or snow recovery scenarios.

Can I cancel my scheduled Subject 3 test?

Scheduled Subject 3 test can be canceled. The cancellation method is: bring your ID card and file to the vehicle management office to cancel the appointment, and the cancellation will take effect immediately. Subject 3 is part of the motor vehicle driver's license assessment, and it is the abbreviation for the road driving skills and safety civilization driving knowledge test subjects. The road driving skills test includes: preparation for getting on the car, light simulation test, starting, driving in a straight line, shifting gears, changing lanes, parking on the side, driving straight through intersections, turning at intersections, meeting cars, overtaking, turning around, driving at night, etc. The test content varies depending on the type of vehicle you are licensed to drive. The safety civilization driving knowledge test includes: safety civilization driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, and disposal knowledge after traffic accidents.

How to Replace Brake Pads with an Electronic Parking Brake?

The method for replacing brake pads with an electronic parking brake is: 1. Locate the jacking point and lift the vehicle with a jack; 2. Remove the tire; 3. Spread open the brake caliper; 4. Remove the caliper screws and take off the brake pads; 5. Install the new brake pads; 6. Tighten the caliper screws with a wrench; 7. Reinstall the tire and remove the jack. The working principle of brake pads is: by utilizing the friction between the brake pads and the brake drum, as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, thereby stopping the vehicle. The materials used for brake pads are: 1. Asbestos, cellulose, sintered glass; 2. Carbon fiber friction material; 3. Powder metallurgy friction material; 4. Semi-metallic friction material.
