What does the small wrench on the car screen mean?

The wrench light appearing on the car screen is the maintenance reminder light, which does not indicate a vehicle malfunction but serves as a notification that the car requires scheduled maintenance. Below are relevant explanations: 1. Function of the maintenance light: Generally, the maintenance cycle is preset by the manufacturer during production. When the vehicle reaches the predetermined mileage, this maintenance light will illuminate, reminding the owner to perform maintenance. After completing the maintenance, the 4S shop staff will reset the maintenance mileage through a programmed procedure, and the wrench maintenance light will be cleared. 2. Method for manual reset and elimination: Turn off the car's ignition switch; Press and hold both black buttons on the dashboard simultaneously; Then turn on the electrical system so all dashboard lights illuminate; Wait until the wrench light (maintenance reminder) turns off; Release both buttons after the light extinguishes; Restart the ignition switch to complete the process.

Is Subject 4 the Safety and Civilization Theory Test of Subject 3?

Subject 3 Safety and Civilization Theory Test is commonly referred to as Subject 4. Subject 4, also known as the Subject 4 Theory Test or Driver Theory Test, is a part of the motor vehicle driver's license examination. Officially, Subject 3 is divided into two parts: the road test and the Safety and Civilization Theory Test. However, the Safety and Civilization Theory Test of Subject 3 is colloquially called Subject 4. Since this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. In official terms, there is no mention of Subject 4. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 examination was divided into two parts: in addition to the road test, a Safety and Civilization Driving Test, commonly known as 'Subject 4', was added, which includes considerations for 'driving ethics'.

Is It Necessary to Keep a Spare Tire in the Car?

It is necessary to keep a spare tire in the car. Here are some precautions for using a spare tire: 1. Regularly inspect the spare tire: The inspection mainly focuses on tire pressure, wear, and cracks. Replace the tire as soon as possible if the tread wears down to the wear indicator line. If there are fine cracks on the tire sidewall, avoid long-distance or high-speed driving, as high-speed driving can easily lead to a blowout. 2. Do not store oil products with the spare tire: Since tires are primarily made of rubber, storing lubricants or other oil products in the trunk can cause the tire to swell and corrode if they come into contact, significantly reducing the tire's lifespan. If the tire gets stained with oil, promptly wash it off with a neutral detergent. 3. Spare tire lifespan is about 4 years: As tires are rubber products, prolonged storage can lead to aging. Generally, the aging period for tires is about 4 years.

Does the Corolla have a four-cylinder engine?

The Corolla is equipped with a 1.2T four-cylinder engine across all models, delivering a maximum power of 116 horsepower and a peak torque of 185 N·m. Below is relevant information about the engine: 1. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. 2. Classification: This includes internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines, steam engines, etc.), jet engines, electric motors, and more. 3. External Combustion Engine: An external combustion engine refers to an engine where fuel is burned outside the engine. 4.

Can You Add Engine Oil When the Car is Hot?

You can add engine oil when the car is hot. Below are the specific functions of engine oil: 1. Shock absorption and cushioning: When the pressure in the engine cylinder rises sharply, it suddenly increases the load on the piston, piston pin, connecting rod, and crankshaft bearings. This load is transmitted and lubricated through the bearings, providing a cushioning effect against impact loads. 2. Rust and corrosion prevention: The lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 3. Lubrication and friction reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear, an oil film of sufficient thickness must be established between the sliding surfaces to separate them and reduce wear. 4. Cooling: Engine oil carries heat back to the oil tank and dissipates it into the air, helping the radiator cool the engine.
