Spare tires can be used on the road. A spare tire refers to an additional tire for a car, which usually has the same specifications as the original tires. However, some vehicles use spare tires with special-colored rims, compact spares, folding spares, or run-flat tires to remind the owner to inspect and replace the faulty tire promptly. Below are the functions of car tires: 1. Supporting the vehicle's full weight: They bear the vehicle's load and transmit forces and torques in other directions. 2. Transmitting traction and braking torque: They ensure good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and off-road performance. They also work with the suspension to absorb shocks and dampen vibrations during driving. 3. Preventing damage to vehicle components: They protect against severe vibrations and premature wear, enhance high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.

How many points will be deducted for entering the left turn waiting area in advance?

Entering the left turn waiting area in advance is considered running a red light and will result in a deduction of 6 points. Below is relevant information about the left turn waiting area: Definition: The "left turn waiting area" refers to the area where vehicles in the left turn lane must move forward when the straight-through lane in the same direction has a green light, waiting for the signal. The left turn lane is extended by several meters with a white dashed line frame, directly connecting to the middle of the road. These white dashed frames are the designated "left turn waiting area," allowing vehicles in the left turn lane to enter and wait for the turn when the straight-through lane in the same direction has a green light. The range of the left turn waiting area is from the original vehicle stop line to the center of the road, with a slight curve at the end and crossing the pedestrian crossing in the middle. At intersections with a left turn waiting area, traffic signals must follow the rule of straight-through first, then left turn. Note the difference from the left turn guide line. Rule: The "left turn waiting area" is only for left-turning vehicles. When the straight-through lane in the same direction has a green light, even if the left turn signal is red, left-turning vehicles are allowed to enter the "left turn waiting area" at the intersection and wait until the left turn signal turns green before proceeding through the intersection. Drivers should be reminded that the left turn waiting line is not the "stop line." If both the straight-through and left turn signals are red, all vehicles must wait behind the previous stop line. Significance: Roads implementing the "left turn waiting area" are generally one-way roads with three or more lanes. Based on each traffic signal cycle, it is estimated that 3 or 4 more vehicles can pass per cycle, approximately 100 more vehicles per hour. This measure will effectively increase the traffic flow at intersections and reduce vehicle congestion.

What to Do When the Car Indicates Low Washer Fluid?

The solution to the car indicating low washer fluid is: the owner should promptly add windshield washer fluid. Car washer fluid, commonly known as glass water, is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. It can be classified by its properties into: 1. Solid glass water; 2. Liquid glass water. The functions of car washer fluid are: 1. It can eliminate the charge on the glass surface and resist static electricity; 2. It prevents the formation of fog droplets, ensuring the windshield is clear and the view is unobstructed; 3. It reduces friction between the wiper and the glass, preventing scratches; 4. It cleans, removes dirt, and prevents freezing.

What is the function of a vehicle's mass air flow sensor?

The function of a vehicle's mass air flow sensor is to measure the amount of air entering the engine and transmit this data to the engine control unit (ECU). The ECU uses this data to determine the appropriate fuel injection quantity. As one of the crucial sensors in an electronic fuel injection system, the mass air flow sensor converts the intake air volume into electrical signals sent to the electronic control unit, serving as one of the fundamental signals for fuel injection determination. It is essentially a sensor that measures the air flow entering the engine. Symptoms of a faulty mass air flow sensor include: 1. Decreased engine power; 2. Difficult engine starting and unstable operation; 3. Unstable idle speed; 4. Poor vehicle acceleration; 5. Intake manifold backfiring; 6. Black smoke emission from the exhaust pipe.

How to Turn on the Air Conditioning in a Lavida?

The method to turn on the air conditioning in a Volkswagen Lavida is as follows: 1. Press the AC button and turn the temperature knob to the blue section. 2. AC is the air conditioning switch, MAX stands for maximum, and the internal circulation can be manually turned on or off. 3. By default, the air conditioning is set to the maximum state when turned on, or the internal circulation will automatically activate when there is a significant temperature difference between the inside and outside of the car; in other cases, the internal circulation generally does not activate automatically. Additional relevant information is as follows: 1. The Lavida is a compact sedan under Volkswagen, with dimensions of 4670 mm in length, 1806 mm in width, 1474 mm in height, and a wheelbase of 2688 mm. 2.
