There are two main reasons why the battery light comes on while driving: 1. Battery failure, such as depleted power or battery malfunction. The solution is to use a multimeter to test the battery voltage. If the voltage is low, recharge it to restore power. If the battery is faulty, replace it. 2. Loose or oxidized battery terminals causing poor contact can also trigger the battery light. The solution is to clean and tighten the battery connections. A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. The commonly referred to car battery is a lead-acid battery, which is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte.

What does a 40:60 rear seat folding ratio mean?

Rear seat folding ratio 40:60 means that the larger section of the rear seat accounts for 60% and the smaller section accounts for 40%, both of which can be folded down. Rear seat proportional folding refers to the ability to fold down the backrest of the rear seats in a certain ratio. Compared to folding the entire rear seat, proportional folding offers greater flexibility, allowing only half of the backrest to be folded down to accommodate large items while the remaining part can still be used for seating. Full rear seat folding means the backrest of the rear seats is a single unit. When larger objects need to be transported and more space is required, the entire rear seat backrest can be folded down to provide additional space. The drawback of full rear seat folding is that when the rear seats are folded down, they cannot be used for seating.

Should Brake Fluid Be Replaced at 40,000 Kilometers?

Brake fluid should be replaced at 40,000 kilometers. The procedure for replacing brake fluid is as follows: 1. Use a machine to extract the old brake fluid from the drain nut, then continuously add new brake fluid to the reservoir, repeating this process; 2. Continue until the discharged brake fluid is clear and free of air, then use the same method to replace the brake fluid in the remaining three wheels. Brake fluid, also known as hydraulic brake fluid, should be purchased from reliable manufacturers, and the higher the grade, the better. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when pressure is applied to the liquid, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking systems operate based on this principle.
