How to Check the Car's Mileage?

Car mileage can be viewed on the odometer, usually indicated by ODO, with the value followed by the unit kilometers, representing the total driving distance of the car. Here are the specific details about the car odometer: 1. It allows the driver to know the distance traveled, which can be used to calculate fuel costs, indirectly reflecting the car's fuel efficiency. 2. It can display small trip distances, total mileage, and single trip distances can be reset to zero. For current electronic dashboards, the total mileage cannot be reset to zero. Additional information: The method to reset data is to long-press the TRIP key on the average fuel consumption, driving time, or average speed page to clear the related data.

Can I turn on the air conditioning without starting the car?

It is possible to turn on the air conditioning without starting the car. Here are the specific details about using the air conditioning without starting the car: 1. The air conditioning will only blow natural air from the blower, because the air conditioning compressor is driven by the engine's power, and the compressor naturally does not work when the car is turned off. 2. When the car is turned off, the compressor does not work. The natural air blown by the blower is powered by the battery. Eventually, the blower may consume too much power from the battery, which could lead to long-term battery depletion. Additional information: The car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car to a comfortable level, providing a pleasant environment for passengers and reducing travel fatigue. It also creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device.

Why can't the car start when the key is inserted?

Here are the reasons why the car won't start when the key is inserted: 1. When the key can't be turned after insertion and the car fails to start, first check if the steering wheel is automatically locked - this is part of the car's anti-theft system. If the steering wheel is locked, simply turn the steering wheel while simultaneously turning the key to solve the problem. 2. If the key can be turned but the engine won't start, this indicates the starter motor circuit isn't engaged. The cause could be either burnt or loose contacts in the ignition switch assembly - though the key turns, the contacts don't connect, meaning the circuit remains incomplete. Additional information: A car's starting system consists of the battery, ignition switch, starter relay, and starter motor. The system's function is to convert the battery's electrical energy into mechanical energy through the starter motor to initiate engine operation.
