Starting the heater without igniting the engine can easily burn out the wiring. After starting the engine, wait about 10 seconds until the water temperature rises before turning on the heater. First, turn on the external air circulation. After the air inside the car has been completely replaced, switch off the external circulation and activate the internal circulation. This process may take a few minutes. Locate the knob with the AC symbol, then turn the temperature dial to 25 degrees Celsius or higher. This will activate the heater, and the car interior will warm up shortly. When using the heater function of the air conditioning, there is no need to press the AC button. The AC button is only required when using the cooling function.

How Long Does a Car Battery Typically Last?

Car batteries typically last between 3 to 5 years. The battery is a crucial component in a vehicle, as the car cannot operate properly without it. When the engine is not running, the battery supplies power to all the vehicle's electronic devices and is also responsible for starting the engine. While the alternator is running, it generates electricity, which recharges the battery and powers the electronic devices. However, with repeated charging and discharging cycles, the battery's performance gradually declines. During charging or discharging, ions within the battery move through the electrolyte, and some of these ions undergo chemical reactions with the electrolyte as they move.

What is the normal battery voltage?

Normal battery voltage ranges between 11.8V and 12.8V, while the voltage after starting the engine is between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Both excessively high and low battery voltages can have certain impacts, so it is advisable to regularly check the battery's condition. If the battery voltage drops below 10.8V, it should be charged promptly. Precautions for using the battery: 1. Keep the battery clean and dry, ensuring that the vent holes are unobstructed; 2. Do not use the starter continuously, with each use not exceeding 5 seconds, and allow a rest period of 10 to 15 seconds between two starts; 3. A battery with sufficient electrolyte should not be left in a state of insufficient charge for a long time and should be charged regularly, otherwise it may lead to scrapping.

What Are the Reasons for the Engine Not Starting?

Reasons for the engine not starting are as follows: 1. Insufficient fuel. When the fuel gauge shows below the red line, the engine will not start. 2. Dead battery. This could be due to leaving headlights on for an extended period or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit issues. 3. Incorrect gear position. For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start the engine. If it is in R (Reverse) or D (Drive), the engine will not start. Moreover, some manual transmission vehicles require the clutch to be depressed for the engine to start.
