How to Deal with Abnormal Noise from Brake Pads?

What is the ideal tire pressure for the front tires of a sedan?

The recommended tire pressure for the front tires of a sedan is around 2.3 bar. Under normal circumstances, the front tire pressure is higher than the rear tire pressure because the front of the vehicle houses the engine, while the rear, unless frequently loaded with heavy items, is lighter than the front. This results in higher front tire pressure compared to the rear. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum tire pressure should not exceed 3.5 bar. Hazards of excessive tire pressure: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks, blowouts, or even tire bursts.

Where is the Radar Switch on the Highlander?

Current Toyota vehicles are equipped with parking sensors. The parking sensor switch in Toyota vehicles shares the same switch as the reverse lights. More details are as follows: 1. Definition: The parking sensor, also known as the 'reverse collision avoidance radar' or 'parking assist device,' is a safety aid for parking or reversing. It consists of ultrasonic sensors (commonly called probes), a controller, and a display (or buzzer). 2. Function: It informs the driver about surrounding obstacles through sounds or a more intuitive display, alleviating the hassle of checking around when parking, reversing, or starting the vehicle. It also helps eliminate blind spots and unclear vision, enhancing driving safety.

Is there a fine for a bare-chested passenger in the front seat?

No fine. The new traffic regulations do not have specific requirements for driving bare-chested or having a bare-chested passenger in the front seat, and it will not result in being photographed or fined. However, from the perspective of civilized driving norms, this behavior is inappropriate. If caught by traffic police, you may be subject to criticism and education, and advised to correct it. Below are the etiquette requirements for driving: 1. Starting the vehicle etiquette: Fasten the seat belt, turn on the turn signal, avoid pedestrians and vehicles, and start slowly. 2. Parking etiquette: Turn on the turn signal, slow down, and park gently. Remember the eight-character parking rule: position, direction, alignment, and punctuality, ensuring not to obstruct others. 3. Turning etiquette: Turn on the turn signal in advance, reduce speed, and enter the turning lane after confirming safety. 4. Lane-changing etiquette: Turn on the turn signal in advance, and enter the target lane only after confirming that the following vehicle allows overtaking. 5. Yielding to pedestrians etiquette: Slow down at crosswalks, stop and yield when pedestrians are crossing, and let pedestrians go first. 6. Overtaking etiquette: First, turn on the turn signal, enter the overtaking lane, flash the headlights to inform the vehicle ahead, and confirm that the vehicle ahead allows overtaking before proceeding. 7. Meeting etiquette: When two vehicles are approaching each other, promptly remind the other vehicle to pay attention to safety. At night, switch to low beams when the vehicles meet.

Driving at 120 km/h in rainy weather when the speed limit is 80 km/h on the highway is not considered speeding, but it does increase the risk of driving. Here are specific details about highways: 1. Definition: A highway, also known as an expressway, is a road specifically designed for high-speed automobile travel. The definition of a highway varies by country, region, era, and different academic fields. 2. Service facilities: Along highways, service areas are typically located every 50 kilometers on average, equipped with gas stations, parking lots, rest areas, restaurants, restrooms, and auto repair shops. Service areas are essential supporting facilities within highways, providing necessary safety measures for long-distance travel.

How Often Should Spark Plug Wires Be Replaced?

Spark plug wires generally need to be replaced approximately every 40,000 kilometers. Below are detailed explanations about spark plug wires: 1. Function: Spark plug wires serve as the medium through which the ignition coil transfers energy to the spark plugs. When experiencing symptoms such as engine shaking or misfiring, it is crucial to inspect the spark plug wires and replace them if necessary. 2. Composition: Automobile spark plug wires, commonly referred to as distributor wires, transmit the high-voltage spark from the distributor to the spark plugs, enabling ignition and combustion within the cylinders to drive the engine. Spark plug wires primarily consist of four parts: conductive material, insulating rubber, ignition coil connectors, and spark plug connectors. Some spark plug wires are also wrapped with a layer of heat-resistant material to prevent damage from excessive heat.
