Solutions for when the auto start-stop function doesn't work: Turn off the engine, disconnect the positive terminal of the battery, reconnect it after 5 minutes, insert the key and turn it to ON (dashboard indicators will light up), wait for 30 seconds, then remove the key. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move again. Situations where the auto start-stop may not function properly include: 1. The engine coolant temperature hasn't risen after a cold start; 2. The outside temperature is below 5 degrees or the inside temperature is below 20 degrees with the heater on; 3. Insufficient battery charge; 4. The steering wheel angle exceeds 30 degrees; 5. Front seat belts are not fastened; 6. Parking on a slope.

What does Anti-lock Braking System mean?

Anti-lock Braking System, or ABS, is a technology developed by Robert Bosch GmbH for use in motorcycles and automobiles. It helps prevent loss of control of the vehicle and generally increases braking distance to improve vehicle safety, thereby enhancing the safety factor of emergency braking while driving. ABS mainly consists of an ECU control unit, wheel speed sensors, brake pressure regulation devices, and brake control circuits. During braking, the ABS control unit continuously receives speed signals from the wheel speed sensors, processes them, and determines whether the wheels are about to lock up.

What are the symptoms of timing belt aging?

Symptoms of timing belt aging include reduced hardness, wear, fiber breakage, cracks, or fissures. Below are the functions and usage precautions of timing belts: Functions of timing belts: The main function of the engine timing belt is to drive the engine's valve train, ensuring that the intake and exhaust valves open or close at the appropriate times to allow normal air intake and exhaust in the engine cylinders. Precautions for using timing belts: During use, regularly inspect the condition of the timing belt. If cracks are observed on the surface of the timing belt, pay attention to whether the belt is aging. If there are abnormal noises while driving, check whether the timing belt is installed correctly.

What does the fault code P2138 mean in Dongfeng Nissan vehicles?

Dongfeng Nissan vehicle fault code P2138 indicates a malfunction in the throttle or accelerator pedal sensor. The solution is to have the fault repaired at a repair shop or 4S store, and then clear the fault code. Throttle failure: When the throttle fails, the vehicle may exhibit symptoms such as engine shaking, unstable idle speed, weak acceleration, and difficulty starting when cold. In this case, the throttle needs to be cleaned again, especially the oil sludge attached to the throttle, which must be thoroughly removed. Accelerator pedal sensor failure: When the accelerator pedal fails, the vehicle may show problems such as weak acceleration, severe jerking, and failure to move when accelerating. In this situation, the accelerator pedal sensor should be inspected, and it is also important to use high-quality fuel daily. Dongfeng Nissan Passenger Vehicle Company was established in June 2003 and is an important passenger vehicle division under Dongfeng Motor Co., Ltd. It is engaged in the research and development, procurement, manufacturing, sales, and service of NISSAN brand passenger vehicles, making it one of the domestic automotive enterprises with a complete value chain.

How long can you drive after the low engine coolant level warning?

It is best not to continue driving after the low engine coolant level warning. If you continue driving, the engine temperature will rise rapidly and without the cooling effect of the coolant, it can cause engine damage. Car owners should regularly check the vehicle's cooling system and the remaining engine coolant level. If the engine coolant is found to be insufficient, it should be replenished promptly. Engine coolant prevents the coolant from freezing during cold seasons, which could crack the radiator and damage the engine block. Its main function is to maintain the operating engine within a normal temperature range, cooling it down when it overheats. Additionally, engine coolant also has anti-freeze, anti-corrosion, and anti-scaling properties.

What is the difference between a 7-speed dual-clutch and a 6-speed manual-automatic transmission?

The differences between a 7-speed dual-clutch and a 6-speed manual-automatic transmission are: 1. Different definitions: A 7-speed dual-clutch is a dual-clutch transmission with 7 forward gears; a 6-speed manual-automatic is a transmission that combines 6-speed manual and automatic modes. 2. Different shifting effects: The 7-speed dual-clutch makes gear shifts smoother, without any jerking or hesitation; the 6-speed manual-automatic allows for flexible switching between gear modes depending on different driving conditions. 3. Different working principles: The 7-speed dual-clutch transmission can achieve 7-speed variations, and the clutch separation and engagement can occur simultaneously; the 6-speed manual-automatic transmission has 6-speed variations, integrating manual and automatic transmissions into one, allowing the driver to choose between manual or automatic mode.
