Why is the Corolla's automatic light always on?

What Causes the Engine Malfunction Indicator Light to Illuminate?

Engine malfunction indicator light illumination indicates a fault in the engine, which can be caused by: 1. Poor-quality gasoline or excessive engine carbon deposits leading to suboptimal combustion; 2. Failure of the engine's oxygen sensor; 3. Clogged fuel injectors or intake valves due to carbon buildup. During vehicle self-test when turning on the ignition, the engine fault light will illuminate, but it should turn off once the engine starts running. If this light remains on or flashes while driving, it signifies an engine issue requiring immediate inspection. Note that not all instances of engine light illumination prohibit driving - if there are no abnormal noises under the hood, no other warning messages on the dashboard, unaffected vehicle power, and normal transmission shifting, you may proceed to a 4S shop for further diagnosis.

Does the car air conditioning water tank need to be filled with water?

Car air conditioning does not require water. Modern air conditioning systems consist of the following components: 1. Ventilation system: It is essential to ensure indoor ventilation while the car is in motion, which means continuously introducing fresh air into the car interior to expel dust, carbon dioxide, and harmful gases from the engine. During cold winters, the fresh air should also be heated to maintain a suitable indoor temperature. 2. Heating system: It heats the air inside the car or the fresh air entering from outside to achieve the purposes of warming and dehumidifying. 3. Refrigeration system: It lowers the temperature inside the car when the external environment temperature is high, making passengers feel cool and comfortable. 4. Air purification system: It filters the introduced air and continuously removes foul gases from the car interior to keep the air inside clean.

What should be filled in for vehicle attributes?

Below is the relevant introduction to vehicle attributes: 1. Vehicle attributes: Vehicle attributes should be filled in as either 'operational' or 'non-operational'. Operational refers to earning income by transporting passengers or goods, while non-operational means not earning income through transporting passengers or goods, generally referring to ordinary private cars. 2. License plate registration: When registering a vehicle's license plate, you should choose whether to fill in the vehicle's attribute as operational or non-operational based on your actual situation. If you fill in non-operational, the vehicle's insurance premiums and annual inspections will be much simpler compared to operational vehicles. Non-operational generally refers to ordinary private cars. If it is discovered that a vehicle filled in as non-operational is used for taxi services or transporting goods, the owner will be penalized by traffic police.

How many kilometers does the timing belt of the Haval H6 need to be replaced?

The timing belt of the Haval H6 generally needs to be replaced every 60,000 kilometers. Relevant information about the timing belt is as follows: 1. The timing belt is an important part of the engine's valve system. It is connected to the crankshaft and works with a certain transmission ratio to ensure the accuracy of the intake and exhaust timing. The reason for using a belt instead of gears for transmission is that the belt has less noise, minimal variation, and is easy to compensate. Obviously, the lifespan of the belt is certainly shorter than that of metal gears, so the belt needs to be replaced regularly. 2. The timing belt is a consumable item. Once the timing belt breaks, the camshaft will not operate according to the timing, which may cause the valve and piston to collide and cause serious damage. Therefore, the timing belt must be replaced according to the mileage or time specified by the manufacturer.
