How often should the RAV4 transmission fluid be changed?

RAV4 transmission fluid should be changed every 40,000 kilometers. The RAV4 is a compact SUV under FAW Toyota, with dimensions of 4600*1855*1680mm and a wheelbase of 2690mm. It is equipped with a 2.0L naturally aspirated engine, paired with a 10-speed continuously variable transmission, delivering a maximum horsepower of 171Ps and a maximum power of 126kW. Method for changing transmission fluid: Remove the transmission guard plate, loosen the screws on the oil pan, and drain the old transmission fluid; unscrew the oil pan screws and remove the oil pan; apply sealant to the new oil pan and tighten it; loosen the screw on the left side of the transmission to add new fluid. Symptoms of deteriorated RAV4 transmission fluid: Slipping: On slopes or other sections requiring high torque, insufficient lubrication of transmission gears causes slipping; Oil leakage: Issues with transmission sealing; Jerkiness: Deteriorated transmission fluid and debris hinder smooth gear engagement; Abnormal noise: Loud noises from the transmission during driving may indicate deteriorated fluid; Overheating: The dashboard usually displays a transmission overheating warning; Stalling: Possibly due to a damaged input shaft speed sensor.

The Three Major Components of the Atenza and the Camry

The three major components of the Atenza and the Camry refer to the car's engine, transmission, and chassis. Below are the relevant introductions: Engine: The engine is known as the heart of the car, serving as the power source. Most car engines are thermal power devices, commonly referred to as heat engines. Heat engines convert the thermal energy generated by fuel combustion into mechanical energy through changes in the state of the working medium. They determine the car's power, fuel efficiency, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrids. Transmission: The car's transmission is divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations. Automatic transmissions (AT), on the other hand, are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system. They achieve speed and torque variation through hydraulic transmission and gear combinations. Chassis: The car chassis consists of four parts: the transmission system, the running system, the steering system, and the braking system. The chassis supports and installs the car engine and its various components and assemblies, forming the overall shape of the car. It also receives the engine's power to enable the car's movement and ensure normal operation.

Is the driving resistance greater or smaller in rainy weather?

When driving in rainy weather, the resistance is smaller. Here is the relevant introduction: What is resistance: Resistance is the force generated by friction, determined by the coefficient of friction and the mass of the object. When driving in the rain, the rainwater on the road acts as a "lubricant" between the road and the tires, reducing the coefficient of friction, thus decreasing the driving resistance. The reason why accidents are more likely to occur when driving in the rain is because the reduced driving resistance can lead to skidding. Precautions for driving in the rain: Control your speed. Since the driving resistance is reduced in rainy weather, driving too fast can easily cause skidding. Therefore, the speed should be controlled within 40-60 km/h, and you should drive slowly and cautiously. Maintain a safe distance. The braking distance on wet roads is three times that on dry roads. The distance between vehicles should be kept at 10-20 meters, and you should always observe the distance between the front and rear vehicles to increase the safety margin. Prevent tire side-slip when driving on curves: The rainwater on the road acts as a "lubricant" between the road and the tires, reducing tire friction and making side-slip more likely. When turning, avoid sudden braking or sharp steering. Instead, use "pump braking" to decelerate in a straight line before entering the curve. Turn on the windshield wipers promptly. In rainy weather, use the windshield wipers to maintain good visibility. Additionally, turn on the low beams, fog lights, and contour lights, and pay attention to pedestrians, slowing down as necessary. Reduce fogging. The windshield is prone to fogging up in rainy weather, obstructing visibility. To reduce fogging, turn on the air conditioner and direct the airflow toward the windshield.

Driver's license photo size?

Driver's license photo size is 2.5cm×3.5cm. Here are the relevant details: The photo size is measured in inches, with 1 inch = 2.54cm. Typically, X inches refers to the length of the longer side of the photo. All photos must be recent, front-facing, color headshots without hats, with the head occupying 2/3 of the photo size. The background should be white with no borders, and the image should be clear, with rich layers, natural expression, and no obvious distortion. Additional information: Materials required for the driver's license test: For local residents, the required documents are household registration book and valid ID card. For non-local residents, the required documents are ID card and temporary residence permit. Submit the "Motor Vehicle Driver Physical Condition Certificate," along with one recent 1-inch color front-facing half-length photo with a white background and no hat.

Can You Practice Driving in Heavy Rain?

You can practice driving in heavy rain. Here are some relevant introductions about practicing driving: Practicing on roads with less traffic: Many people are actually afraid to drive on the road after getting their driver's license, so at this time, they need to practice on roads with no traffic. Of course, having an experienced driver by their side can provide some safety assurance. First, practice smooth starts, straight-line driving, turning, acceleration and deceleration, and other operations well. Practicing on provincial roads or areas with heavy traffic: After practicing in areas with less traffic, it is necessary to practice in areas with more traffic. The most ideal place is a provincial road, as there is more traffic, but you can control your speed well. Moreover, it not only helps improve driving skills but also trains your psychological endurance, provided that you have mastered the basic skills.

What does 155R13LT tire mean?

155 represents the "section width" of the tire, which is the width at its widest point in millimeters. R stands for radial construction, 13 is the rim diameter in inches, and LT indicates a light truck tire. Explanation of tire specification parameters: The international standard tire code expresses the section width and aspect ratio as a percentage in millimeters, followed by the tire type code, rim diameter (in inches), load index (permissible load capacity code), and permissible speed code. Taking 215/70R15 as an example: The meanings of 215/70R15 are as follows: 215 indicates the tire section width in millimeters, with intervals of 10mm; 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, with 70 representing 70%. Generally, the aspect ratio of tires ranges between 30% and 80%. Under normal circumstances, ordinary cars should not use tires with an aspect ratio greater than 75%, while luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio less than 60%. R is the abbreviation for Radial, indicating that the tire has a radial structure, and 15 is the outer diameter of the rim in inches.
