Why Does the Car Get Foggy on Rainy Days?

On rainy days, even during summer, a temperature difference develops between the inside and outside of the car. The outside temperature is lower, while the inside temperature is higher. Consequently, the temperature of the car windows also drops. When the humid air inside the car encounters the cold windows, it condenses into fog. Additionally, the air is more humid on rainy days, and when opening and closing the car doors, water from wet shoes can be brought inside, increasing the humidity in the car and making it more prone to fogging. Here’s a quick solution: Immediately turn on the car’s air conditioning, set the defrost function to maximum, and direct the cold air towards the windows. The fog will typically clear within three seconds.

Can You Drive with 120 kPa Tire Pressure?

Tire pressure of 120 kPa is drivable, but the vehicle can only sustain it for 30-50 km. You should replace the tire or refill the air as soon as possible. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and easy deviation, which are factors detrimental to driving safety; Increases movement in various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the function of the cord and rubber, leading to delamination or cord breakage and excessive friction between the tire and rim, resulting in damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion, leading to excessive heating, accelerating rubber aging, cord fatigue, and breakage, and increasing the tire's contact area, accelerating shoulder wear. Methods to address insufficient tire pressure: If no damage is visible, simply inflate to normal tire pressure and reset the tire pressure system; If the tire is found to be punctured during inspection, drive to a tire shop promptly for repair and then reinflate; If the tire pressure warning reappears after some time of inflation but there is no puncture, it may be due to air leakage caused by rim deformation. It is recommended to check the rim and replace it.

Which gear is for parking?

The parking gear of a car is the P gear. P gear: 'Parking' means 'to park'. It is the parking gear used when parking. When you reach your destination or need to park for a long time, shift the gear lever into this position. Note: You must ensure the vehicle has come to a complete stop before shifting into P gear. Shifting into P gear before the vehicle has fully stopped can cause mechanical damage to the automatic transmission. When P gear is engaged, the wheels are mechanically locked, preventing the vehicle from moving forward or backward. Therefore, always engage P gear when parking on a slope. Automatic transmission cars have gear positions marked with letters such as P, R, N, D, S, and L. The full English names for these gears are: P for Parking, R for Reverse, N for Neutral, D for Drive, S for Sport, L for Low, and M for Manual. Different gear combinations output different levels of power. When the car is moving at different speeds, you need to 'shift gears,' meaning selecting different gear combinations to output power. Below is an explanation of each gear: R gear: 'Reverse' means 'to go backward' and is used when reversing the car. To reverse, press the safety button on the gear lever and shift into R gear. However, it is crucial to ensure the vehicle has completely stopped before performing this operation to avoid severe damage to the transmission. N gear: 'Neutral' means 'in the middle,' also known as the neutral gear. You can shift into this gear and press the brake when waiting at a traffic light. If the wait is longer, it is recommended to engage the handbrake, allowing your foot to rest off the brake pedal. Many people mistakenly believe that shifting into N gear while coasting downhill or at high speed can save fuel. This is a serious misconception—not only does it not save fuel, but it can also damage the transmission. D gear: 'Drive' means 'to move forward' and is the forward gear in a car. When this gear is engaged, pressing the accelerator will make the car move. In this gear, the transmission automatically shifts based on speed and throttle input. You can stay in D gear and press the brake when waiting at a traffic light. If the wait is short, this is fine, but prolonged use can cause the transmission fluid to overheat and degrade. S gear: 'Sport' means 'sport mode' in a car. When this gear is engaged, the transmission delays shifting to provide more power, typically used when overtaking. L gear: 'Low' means 'low speed' and is the low-speed forward gear in a car. When this gear is engaged, the transmission operates only in the low gear (equivalent to manual transmission's 1st gear) and does not automatically shift to other gears based on speed. This gear is generally used when climbing or descending steep slopes. In low gear, the drive wheels output higher torque, providing sufficient power to climb steep slopes. Prolonged braking can cause the brake pads to overheat and reduce braking effectiveness, which is dangerous on long or steep descents. In such cases, shifting into L gear allows the engine's low RPM to control the vehicle's movement, eliminating the need for constant braking.

Should Fuel Additive Be Added Before or After Gasoline?

Fuel additive should be added before gasoline. This allows the fuel additive to mix evenly with the gasoline under the impact of refueling, achieving optimal performance. Below is a detailed introduction: Fuel additive, commonly known as the third-generation gasoline detergent (also referred to as gasoline detergent or fuel additive), is designed to address carbon deposits in the fuel system of fuel-injected vehicles, quickly restore the engine to its optimal operating condition, and compensate for certain deficiencies in gasoline properties while imparting new beneficial characteristics (improved atomization, reduced wear, engine protection, lower emissions, etc.).

Difference Between Wheel Alignment and Wheel Balancing?

1.Wheel balancing refers to the weight deviation between the tire and the steel rim, which manifests as steering wheel vibration within a certain speed range when driving. 2.Wheel alignment is the angular deviation between the chassis components and the wheels, caused by chassis component issues, resulting in effects such as uneven tire wear, vehicle pulling to one side, and an off-center steering wheel. Additional details: 1.Function of wheel alignment: Wheel alignment helps the car maintain stable straight-line driving and easy steering, reducing wear on tires and steering components during driving. 2.Function of wheel balancing: Wheel balancing ensures smooth tire operation, prevents vibration, and enables the vehicle to drive smoothly and safely at high speeds.

How to Use the Remote Start on the Land Cruiser?

Land Cruiser remote start method: First press the lock button, then press the button with the circular arrow symbol to start the engine. Below is some information about the Land Cruiser's remote start feature: 1. The car starts the engine via signals from the remote key. 2. The entire process eliminates the inconvenience of manually entering the car to operate it, and the central locking system remains locked while the engine is running, providing effective security. 3. Typically, after remote starting, the engine will run continuously for ten minutes, and if no further instructions are received, it will automatically shut off. This method can help raise the temperature inside the cabin.
