ION in a car refers to the air purification function. When ION is activated, the air purifier starts working. The new ION system mainly consists of two components: 1. PM2.5 sensor: Function: It measures the PM2.5 content in the air inside and outside the vehicle, serving as the basis for whether to automatically activate ION and displaying the measured PM2.5 concentration on the car's screen. Location: The sensor is installed inside the vehicle's dashboard, to the right of the blower, on the right front A-pillar. 2. Negative ion generator: Function: It boosts the 12V low voltage to hundreds of volts of high voltage, ionizing the air to form negative ions for air purification, dust removal, deodorization, and sterilization. Location: Installed between the blower and the evaporator.

Where is the fuse for the horn of the Chery Eastar?

There are two fuses for the horn of the Chery Eastar, one in the engine compartment and the other above the clutch pedal under the steering wheel. Function of the fuse: The fuse is commonly referred to as such, but its actual name is 'circuit breaker.' Its main function is to blow when the circuit current is abnormal or exceeds twice its rated current, thereby protecting the circuit. Chery Eastar: The 10 upgrades of the Chery Eastar further enhance its business positioning. The new front grille and optimized rear visual effect make the car appear more grand; new features such as automatic wipers, automatic xenon headlights, long-range remote door locks, noise-reducing tires, and user-friendly reading lights well reflect the business characteristics of the Eastar. In addition, the steering system has been recalibrated, and a chassis reinforcement plate has been added to the engine compartment, further improving vehicle performance.

What is the reason for the relatively stiff suspension of the Volkswagen T-Roc?

For vehicles with non-independent suspension, most tend to be softer. However, due to significant body roll during cornering, reducing roll requires a stiffer suspension. Function of shock absorbers: Shock absorbers are used to dampen the oscillations from the spring's rebound after absorbing shocks and impacts from the road surface. Application of shock absorbers: Shock absorbers are widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the ride comfort. When driving on uneven roads, although the suspension springs can filter out road vibrations, the springs themselves still undergo reciprocating motion. The shock absorber is designed to suppress this reciprocating motion of the springs.

Which button to press for fog inside a Mercedes-Benz car?

The defogging button is a rectangular frame with three upward-curved arrows from bottom to top. Reasons for fog formation: Fog forms when the temperature inside the car is higher than the outside temperature. Other defogging methods: If the fog inside the car is not heavy, you can open a crack in the windows on both sides to create air convection between the inside and outside of the car, reducing the temperature difference and gradually dissipating the fog. The principle of this method is the same as turning on the air conditioning's cold air, but it does not increase fuel consumption. However, the downside of opening windows for convection is very obvious: it cannot be used during rain or snow, on highways, or when the fog is heavy, and it will lower the temperature inside the car.

What Causes a BMW to Stall Due to Drivetrain Malfunction?

The main causes of drivetrain malfunction in BMWs include the vehicle's computer failing to respond promptly, leading to program execution issues; damage to the fuel pump or fuel pump sensor; faulty fuel injectors; defective ignition coils; damaged or carbon-fouled spark plugs; and a malfunctioning turbo wastegate. Symptoms of the Malfunction: When the accelerator is pressed abruptly, a drivetrain malfunction warning may appear, sometimes accompanied by vehicle shaking. Overview of Drivetrain Malfunction: Drivetrain malfunction typically refers to issues with components such as the clutch, transmission, universal joint, final drive, differential, and axle shafts. However, in practice, many unrelated problems—like a faulty fuel pump, injectors, solenoid valves, sensors, or even a damaged screw—can trigger a "drivetrain malfunction" warning.
