What is the AUTOHOLD function in cars?

AUTOHOLD automatic parking function refers to a function that automatically brakes the vehicle through the ABS/ESP control unit. The following is a description of the AUTOHOLD function: 1. The application of AUTOHOLD automatic parking technology allows the driver to avoid unnecessary vehicle coasting without the need for prolonged braking or engaging the electronic parking brake. 2. This function also prevents the vehicle from rolling back when starting on a slope. Traditional parking brake devices require the driver to rely on experience and manually engage the handbrake when starting on a slope. However, the AUTOHOLD automatic parking function provides precise parking force through the slope sensor controlled by the system. 3. When starting the vehicle, the parking control unit uses information from sensors such as the clutch distance sensor, clutch engagement speed sensor, and accelerator pedal sensor to calculate and automatically release the parking brake when the driving force exceeds the driving resistance, ensuring a smooth start.

What does it mean when the fuel reaches the reserve level?

The fuel reaching the reserve level means that the remaining fuel in the tank is low. When the fuel warning light comes on, please refuel promptly to avoid being unable to start the vehicle due to insufficient fuel. Properly place the fuel nozzle: Avoid fuel overflow, which can cause fires or even explosions. Close the fuel tank cap: After refueling, repeatedly check whether the fuel tank cap is securely locked, as driving with it open is highly unsafe. Exit the vehicle immediately: During refueling, all passengers should avoid staying inside the vehicle; if staying inside, make sure to close the doors. Static electricity is another important consideration when refueling—discharge static electricity before handling the fuel nozzle by touching a metal object. Turn off all power: Cut off all power sources while refueling to prevent accidents.

What Causes the Emission System Malfunction?

The reasons for the emission fault light to illuminate are as follows: 1. Poor fuel combustion state, where fuel is not burned or incompletely burned, engine knocking, excessively high engine temperature, necessitating throttle cleaning. 2. Poor fuel quality. The engine has relatively high requirements for fuel quality. Poor fuel quality can lead to unclean engine cylinder interiors with deposited carbon buildup, requiring engine carbon deposit cleaning. 3. Cold start, when the weather temperature drops sharply, the pollution light may illuminate due to the computer's temperature correction issues during startup. The light will stabilize once the temperature drops to a certain level and stops fluctuating. 4. Carbon deposits on the piston top can cause poor atomization, weakened spark plug performance, and ignition coil faults leading to poor ignition. 5. Faults in the oxygen sensor itself or its wiring, or faults in the sensor control unit. An oxygen sensor inspection is required.
