What does a white license plate represent?

A white license plate represents special vehicle license plates, such as military vehicles, police vehicles, and racing cars. The types of license plates include: 1. Blue represents ordinary small vehicles with fewer than 7 seats; 2. Yellow represents ordinary large vehicles; 3. Black represents foreign enterprise license plates. The functions of license plates are: 1. To number and register information for each vehicle; 2. To identify the region to which the vehicle belongs; 3. To trace the owner and registration information of the vehicle based on the license plate. The installation method for license plates is: 1. Take out the screws of the license plate and rotate them into the anti-theft caps; 2. Position the license plate correctly, align the screws with the gaps on the bumper, and secure them with tools; 3. Cover the anti-theft caps and press them into place.

What Causes High Idle Speed in Cars?

The reasons for high idle speed in cars are: 1. The idle switch does not close; 2. Malfunction of the idle control valve; 3. Air leakage in the intake pipe; 4. Incorrect valve timing; 5. Fuel injector dripping or clogging; 6. Blockage in the exhaust system; 7. The EGR valve opens during idle conditions. The solutions for high idle speed in cars are: 1. Check the throttle opening; 2. Check the engine load signal; 3. Check the vacuum level in the intake manifold; 4. Reset the engine control unit; 5. Check whether the throttle is fully closed during idle and if the throttle cable is stuck; 6. Readjust the idle program; 7. Check for air leaks at the intake system pipe joints and vacuum hoses; 8. Perform fault self-diagnosis; 9. Check the coolant temperature sensor; 10. Check the crankcase forced ventilation valve.

What maintenance items does a car need at 15,000 kilometers?

The maintenance items required for a car at 15,000 kilometers are: 1. Replacement of engine oil and oil filter; 2. Check whether the oil filter element, air filter element, gasoline filter element, air conditioning filter element, and transmission oil filter element need to be replaced; 3. Top up windshield washer fluid, antifreeze, and air conditioning refrigerant if insufficient; 4. Check the drive belt for wear; 5. Clean the throttle valve and carbon deposits in the cylinders; 6. Inspect the chassis for damage; 7. Check the body and tires. The benefits of car maintenance include: 1. Ensuring the vehicle is in excellent performance condition; 2. Improving vehicle efficiency and reducing wear on parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Keeping the vehicle's appearance clean and preventing damage.

What is the normal tire pressure for the Highlander?

The normal tire pressure range for the Highlander is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. Some Highlander models are equipped with a tire pressure display function. There is a menu selection on the steering wheel; press to the instantaneous fuel consumption, then press the directional key down to display the tire pressure. The tire pressure monitoring system is a type of active safety device that can alert the driver in time when there are dangerous signs in the tires, prompting the driver to take corresponding measures to avoid serious accidents. Generally speaking, a tire pressure exceeding 2.8bar is too high, and a tire pressure below 2.0bar is too low. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates the wear of the central tread pattern of the tire, reducing tire lifespan; increases body vibration, indirectly affecting the lifespan of other components; it can cause excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body, and increasing the load on the car while driving. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, among other factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the function of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; the friction between the tire and the ground increases exponentially, the tire temperature rises sharply, the tire softens, and its strength drops sharply. High-speed driving may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle without a seal on top, with four small spikes below and an exclamation mark inside), there are generally three reasons: Abnormal tire pressure. It usually alarms when the pressure is below 1.8bar or above 3.0bar. At this time, tire inspection and pressure adjustment are needed. The tire pressure monitoring has not been reset. After inflating the tires, the tire pressure was not reset in time, causing the tire pressure monitoring system to still record the original data, and the tire pressure monitoring indicator light will remain on. At this point, simply reset the tire pressure. The tire pressure sensor is damaged. The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged while driving, it will also cause the tire pressure fault light to come on. For sensor damage issues, only a new replacement part can be used.

What is the appropriate speed to drive on the highway in rainy weather?

When driving a car in rainy conditions, the appropriate speed should be determined based on the intensity of the rain and the type of road. If driving on a highway, it is advisable to maintain a speed below 80 km/h during heavy rain, while light rain may allow for speeds around 100 km/h. If visibility is significantly reduced, the speed should be adjusted accordingly. Driving speed in rainy weather: On regular roads, regardless of road conditions, width, or rain intensity, it is essential to reduce speed. A recommended speed is between 30 km/h and 40 km/h. This is because rain reduces the friction between the road surface and tires, and higher speeds may cause tire slippage or skidding, which can be extremely dangerous and may lead to collisions, rollovers, or drifting. Maintaining good visibility: In rainy conditions, it is necessary to turn on the windshield wipers. If the weather is dark, the low beam headlights and fog lights should also be activated. If there is fogging on the interior windshield, the air conditioning should be used to clear the fog. Additionally, the rearview mirrors should remain clear to ensure proper observation of the rear of the vehicle.
