What does the driving license subject 2 test include?

Subject 2 includes the following tests: 1. Reverse parking: During the reverse parking test, you cannot pause midway. Therefore, you need to flexibly control the vehicle speed while reversing and learn to use the rearview mirror to judge the parking space lines to avoid crossing the lines during the test. 2. Parallel parking: While driving, pay attention to your sitting posture as incorrect posture may affect your judgment of reference points. During reversing, you cannot cross the lines or pause midway. 3. Hill start and stop: When stopping at a designated point, failing to accurately locate the point may result in point deductions. During the start, the vehicle may stall easily. When performing the hill start operation, you need to control the clutch properly and release it slowly, as releasing it too quickly may cause the vehicle to stall. 4. 90-degree turn: Pass through the 90-degree turn slowly without stopping midway, as stopping will result in point deductions. During the turn, try to stay close to one side. 5. Curve driving: The purpose of curve driving is to enable learners to use the steering wheel flexibly.

Does it matter if the car lights are left on after the engine is turned off?

Leaving the car lights on after the engine is turned off can have consequences, including: 1. Automatic light shut-off; 2. Draining the battery's energy. The types and functions of car lights are: 1. Brake lights: Warn people or vehicles behind; 2. Turn signals: Alert vehicles and pedestrians in front, behind, or to the sides; 3. License plate lights: Illuminate the car's license plate at night; 4. High beams: Check distant road conditions; 5. Low beams: Clearly see the road ahead; 6. Fog lights: Strong penetration in fog, making it easier for vehicles and pedestrians to notice; 7. Daytime running lights: Draw attention from other traffic participants; 8. Hazard warning lights: Alert vehicles behind to yield.

Where is the windshield wiper switch located?

The windshield wiper switch is located on the left rear lever of the steering wheel, which includes switches for both the front and rear wipers. Below is an introduction to windshield wipers: Introduction: A windshield wiper is a blade structure installed in front of the windshield, consisting of components such as an electric motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Function: The windshield wiper is used to remove dust and raindrops adhering to the car's windshield, effectively improving the driver's field of vision and enhancing driving safety. Principle: The power source of the windshield wiper comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor.

What Are the Effects of Severe Brake Disc Wear?

The effects of severe brake disc wear are as follows: 1. Reduced braking power. 2. Brake vibration and abnormal noises. 3. Damage to the brake disc, leading to premature and excessive wear. 4. In severe cases, it may damage the braking system. Methods to determine whether the brake disc needs replacement are as follows: 1. Listen for sounds. If abnormal noises occur when lightly applying the brakes, it indicates the brake pads have exceeded their limit and must be replaced immediately. 2. Check the thickness. Most brake discs have wear indicators. When the total wear depth on both sides reaches 3mm, it is recommended to replace the brake disc promptly.

How often should the Haval H6 cylinder be replaced?

Haval H6 cylinders do not have a usage limit and cannot be replaced individually. The working principle of an automobile cylinder is to guide the piston in performing linear reciprocating motion within the cylinder. In the engine cylinder, air converts thermal energy into mechanical energy through expansion; in the compressor cylinder, gas is compressed by the piston to increase pressure, thereby providing a power source. Below are the classifications of cylinders: Single-acting cylinder: Only one end has a piston rod. Air is supplied from one side of the piston to generate pressure, which pushes the piston to extend and produce thrust, while returning via spring or self-weight. Double-acting cylinder: Air is alternately supplied from both sides of the piston, generating force in one or two directions. Diaphragm cylinder: Uses a diaphragm instead of a piston, generating force in only one direction and resetting via spring. It has excellent sealing performance but a short stroke. Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of high-speed piston movement (10-20 m/s) to perform work. The impact cylinder includes a middle cover with a nozzle and a drain port.
