BYD DM-i, like regular hybrid vehicles, requires maintenance every 5,000 kilometers of hybrid driving or once a year. The DM-i engine can support 4-5 minutes of pure electric driving with just one minute of charging. Once the battery reaches the preset level, you can manually switch to EV mode for driving. Relevant information about vehicle maintenance is as follows: 1. Introduction: Vehicle maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of the vehicle, also known as vehicle servicing. 2. Maintenance Scope: Modern vehicle maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas.

I remember when I just bought my BYD DM-i, after driving it for about half a year, the official manual recommended a maintenance cycle of every 7,500 kilometers or 6 months, regardless of whether I usually drive in pure electric mode or hybrid mode, I have to stick to the schedule. I mostly drive in the city, but occasionally take long trips. The maintenance includes changing the engine oil and filters, as well as inspecting the high-voltage battery and motor connections of the hybrid system. If the road conditions are poor, such as frequent traffic jams or dirt roads, I would check the tires and brake pads in advance. Regular maintenance helps avoid small issues turning into big troubles and extends the battery life—after all, prevention is better than cure when it comes to saving money on repairs or replacements. I recommend using the vehicle app to set reminders so you don’t miss the mileage or time points. Safety comes first; a reliable vehicle ensures peace of mind while driving.

Why can't the car key open the door?

The reasons why the car key cannot open the door are: 1. The remote key is out of battery; 2. The car battery is out of power, or there is strong signal interference around; 3. You can use the hidden mechanical key inside the remote key to open the door. If the mechanical key also cannot open the door, it is a door lock malfunction. If the car battery is out of power, the car's sensing system will naturally fail, resulting in malfunction. In this case, the car needs to be recharged. A common issue is the car key battery running out of power, leading to malfunction. Generally, the battery life of a car sensing key is about 2 years. If the battery is dead, the door cannot be opened via sensing. For cars with a one-button start, if the key battery is dead, you can only use the spare key inside the sensing key to open the door.
