JAC truck's EPC light indicates that the engine temperature is too high, which is caused by the engine oil level being below the normal height. It is necessary to add engine oil to cool it down, and the light will automatically turn off. Below is relevant information about EPC light faults: 1. Explanation of reasons: The EPC warning light staying on indicates a fault in the engine management system or electronic control, often accompanied by unstable idling or engine cold start shaking. However, for domestic vehicle owners, this is usually caused by the quality of domestic fuel and a dirty driving environment. It is recommended to drive to a maintenance service station as soon as possible for inspection and repair. In most cases, cleaning the throttle body can resolve the issue. 2. Precautions: If the EPC light is on without any fault symptoms, you can continue driving, but timely maintenance and inspection are still required.

What type of oil does the Kicks use?

Nissan Kicks recommends using genuine Japanese fully synthetic engine oil with a specification of 0W-20. Owners can choose based on their vehicle's operating environment. An oil change generally requires 4 to 6 liters. If topping up, simply add oil to between the upper and lower marks on the dipstick. Below are some precautions for oil usage: 1. Do not mix old and new oil. Old oil contains a large amount of oxidative substances, and mixing it with new oil will accelerate the oxidation and degradation of the new oil, reducing its effectiveness and lifespan. 2. Do not mix oils of different brands or specifications. Since different brands and grades of oil contain different chemical additives, these additives may react with each other, reducing lubrication effectiveness and producing acidic or alkaline compounds that can accelerate corrosion of engine components. Mixing two types of lubricants may result in separation, cloudiness, and deterioration of cleaning performance.

Is it useful to continue driving with zero tire pressure?

Continuing to drive with zero tire pressure is useful. This makes it easier to control the vehicle body when a tire blows out. Below are some related introductions about zero tire pressure: 1. Continuing to drive with zero tire pressure means that the vehicle can still drive at low speeds for several tens of kilometers when the tire is flat or the tire pressure is too low. Zero tire pressure refers to run-flat tires. Run-flat tires do not mean they won't blow out; they are also called air-loss-resistant tires. There is not much difference in structure between run-flat tires and ordinary tires, except that the sidewalls of run-flat tires are reinforced. 2. The main advantage of run-flat tires is safety. Compared with ordinary tires, the tread design of run-flat tires is thicker and more robust, and the sidewalls have strong resistance to deformation.
