If you know the password, you can input it using the radio buttons 1, 2, 3, and 4, then press the power button and the fast-forward button to confirm. A beep sound will indicate successful unlocking. If you have the necessary equipment, you can directly decode it using a programmer. When manually entering the code, be careful not to press the wrong buttons or input incorrect codes. You are only allowed two incorrect attempts at a time. Exceeding this limit will permanently lock the system, requiring a 24-hour wait before retrying.

Why does the Sagitar fail to start with a clicking sound and all warning lights on?

Here are the reasons why the Sagitar fails to start with a clicking sound and all warning lights on: Insufficient voltage: Low voltage may also cause the car to fail to start with a clicking sound. The reasons for insufficient voltage may be due to the battery being too old and in a state of aging, resulting in reduced stored power; or the vehicle's power being insufficient due to listening to music or turning on the air conditioning without starting the car. Improper operation: It could also be that the gear is not in the P position when starting. Friends who drive manual transmission cars usually won't encounter this problem, as in most cases, they stop the car, shift to neutral, pull the handbrake, and turn off the engine in one smooth motion. However, friends who drive automatic transmission cars, because they don't need to frequently operate the gear lever, might forget to shift to P or leave it in N when parking. Then, when starting the car, they might not notice and try to start it directly, resulting in the car failing to start.

Can the battery of a Zhidou still be used after 5 years?

It depends on the specific usage conditions of the owner. Generally, the battery of a new energy vehicle can last 7-8 years. It is recommended to visit a maintenance facility to test the battery and check its performance before deciding whether to replace it. The classification of new energy batteries is introduced as follows: Lithium Iron Phosphate (LiFePO4) Battery: Lithium iron phosphate batteries have excellent thermal stability, are safe, cost-effective, and have a long lifespan, but they have low energy density and are sensitive to low temperatures. The internal chemical composition begins to decompose when the battery temperature reaches 500-600°C, and they do not catch fire or explode due to punctures, short circuits, or high temperatures, with a relatively long service life. However, the vehicle's range is generally limited, and when the temperature drops below -5°C, charging efficiency decreases, making them unsuitable for winter charging in northern regions. Ternary Lithium Battery: Ternary lithium-ion batteries have high energy density, long cycle life, and are resistant to low temperatures, but they have insufficient stability at high temperatures. They can achieve the highest energy density, but their high-temperature performance is relatively poor. For pure electric vehicles with range requirements, they are the mainstream choice and are suitable for northern climates, as the battery remains more stable in low temperatures.
