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.

How many hours does car maintenance take?

Maintenance typically takes about 1 hour. The duration depends on the maintenance items. For simple tasks like oil and oil filter change, air filter replacement, or cabin air filter replacement, it usually takes around 1 hour including car washing time. For more comprehensive services like oil change with three filters, transmission fluid replacement, catalytic converter cleaning, or throttle body cleaning, the maintenance will take at least 2 to 3 hours. The maintenance time is directly proportional to the number of service items. Car maintenance precautions: Generally, minor maintenance should be performed every six months or every 5,000 kilometers driven. Depending on the number of vehicles in the shop and staff workload, minor maintenance usually takes between twenty minutes to one hour. The main tasks include oil and filter change, air filter inspection, etc. First car maintenance time: The first maintenance should be performed when the car reaches 5,000 kilometers or one year of use, while the second maintenance should be done at 10,000 kilometers or two years of use. The main focus is on inspecting the three major components: engine, chassis, and transmission.

Under What Circumstances Is the Rear-Ending Party Not Fully Liable?

In traffic accidents involving rear-end collisions, the following situations do not result in full liability for the rear-ending party: Rear-end collision caused by the front vehicle reversing or rolling back: If you encounter a situation where the front vehicle is reversing or rolling back, do not rush to reverse to avoid it. In such cases, the front vehicle is usually fully liable for the rear-end collision. Rear-end collision caused by the front vehicle driving over the line: During driving, if the front vehicle is driving over the line (whether it's a dashed or solid line) or makes an emergency lane change, resulting in a rear-end collision with the following vehicle, the front vehicle will bear the liability for the accident. However, there is a condition for this situation: the front vehicle's action of crossing the line must have affected the normal driving of the following vehicle, leading to the rear-end collision. If the front vehicle is stopped at a red light or in traffic and remains stationary, and the following vehicle rear-ends it, the following vehicle is still fully liable because the front vehicle did not affect the normal driving of the following vehicle.

How Often Should a Truck Be Maintained?

Trucks generally require their first maintenance at 5,000 kilometers. The engine oil should be changed every 5,000 kilometers. During the oil change, it's recommended to replace all three filters simultaneously, while the gear oil should be replaced every 20,000 kilometers. Wheel maintenance should be performed every six months. For long-distance trucks or dump trucks, maintenance should be done monthly, with brake adjustments every half month. Basic maintenance items for large trucks include: Changing the engine oil and three filters (oil filter, air filter, and diesel filter); Wheel hub maintenance: Due to their heavy load capacity, large trucks use tapered bearings that require high-grade grease. Truck first-level maintenance inspection items: Replace engine oil, oil filter, fuel filter, and air filter; Check if the coolant level meets specifications; Inspect the brake and clutch fluid levels; Verify if the power steering fluid reservoir level complies with regulations, and check all system oil pipe interfaces for leaks.
