What to Do When the Car Exhaust Warning Light Comes On?

Solutions for when the car exhaust warning light comes on: 1. Start and turn off the vehicle three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it; 2. The exhaust system warning light often comes on due to damage to the oxygen sensor in the three-way catalytic system or poisoning of the catalytic converter caused by poor fuel quality in the country. If the light comes on while driving, immediately reduce speed and drive to the nearest service station for inspection; 3. If the exhaust warning light comes on and the vehicle cannot start after turning off, this is usually due to a malfunction in the fuel pump or ignition system. If the vehicle can still be driven but exhibits severe shaking, lack of acceleration power, and other symptoms, it is recommended to stop driving. This not only prevents further damage to the engine but also ensures personal safety.

What are the methods to improve car handling?

Methods to improve car handling: 1. Replace shock absorbers: Coilover shock absorbers usually have stiffer springs than the original ones, providing a more stable feeling at high speeds. The optimized damping design can better control body movement during cornering compared to factory shock absorbers, reducing the probability of losing control; 2. Add body reinforcement parts: For example, a strut bar connects the subframe and strut towers into a square shape, increasing steering sensitivity due to the rigid connection; 3. Replace anti-roll bars: During cornering, when one side's shock absorber is compressed, the anti-roll bar twists along with it. Due to the characteristics of spring steel material, a counterforce is generated to resist the compression of the shock absorber, thereby controlling the body roll during cornering.

What is the AC in a sedan?

The AC in a sedan is the air conditioning cooling switch. Only when this button is pressed does the car's air conditioning compressor start working, blowing cold air from the vents to lower the temperature inside the car. In hot summer weather, you need to turn on the AC button, which activates the compressor inside the car to blow cold air. The car air conditioning cooling system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower, among others. These components are connected by copper pipes and high-pressure rubber hoses to form a sealed system. When using the air conditioning for heating in winter, the AC light being on does not help with heating at all. Instead, it causes unnecessary power loss due to the compressor's operation. In northern winters, when using the air conditioning for heating, the AC can be completely turned off without any impact on the heating function.

What is the function of a snorkel?

The function of a snorkel: It raises the position of the engine's air intake, ensuring that the engine does not suck in water when the off-road vehicle is wading, which helps the engine work more efficiently and allows it to intake air more fully. The true purpose of a snorkel is to assist the engine in functioning properly, enabling it to breathe fresh air and perform with greater power. When a vehicle is wading through water and the engine stalls, do not attempt to restart the engine. Restarting the engine in such conditions may cause the engine connecting rods to deform or even lead to cylinder block damage, which can severely harm the engine. If the engine's air intake is submerged in water, the engine will stall because it cannot draw in air. However, if the exhaust pipe is submerged, it is not a problem as long as the engine does not stall. Water cannot enter the exhaust pipe as long as exhaust gases are continuously being expelled; the flow of exhaust gases prevents water from entering.

How to use the Camry HOLD function?

After starting the vehicle, press the HOLD button, and a green HOLD light will illuminate on the instrument panel. For example, when waiting at a traffic light, stepping on the brake will change the HOLD button light to orange, indicating that the vehicle has come to a complete stop. Below is relevant information about the HOLD button: 1. HOLD is the button for autohold, with EV next to it representing pure electric mode. The prerequisite for selecting pure electric mode is that the battery meets certain charge level conditions. P is the electronic parking brake button. The English name for automatic parking is AUTOHOLD. This function is equivalent to stepping on the brake; it continues to provide parking braking force even after releasing the brake pedal. This feature is particularly useful on slopes and during frequent starts and stops. 2. Traditional handbrakes require the driver to manually release the parking brake or skillfully coordinate the throttle and clutch for a smooth start on slopes. The AUTOHOLD automatic parking function uses a slope sensor to provide precise parking force through the controller. During startup, the parking control unit calculates information from sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the running resistance, it automatically releases the parking brake, ensuring a smooth start.

How to Replace the Air Conditioning Filter in a GS4?

Here are the detailed steps to replace the air conditioning filter in a GS4: 1. First, open the glove compartment cover of the Trumpchi GS4. Locate the fixing buckle on the right side of the glove compartment and pull it outward with force to remove the glove compartment. Once removed, you will see the air conditioning filter cover plate. The air conditioning filter is located on the passenger side, beneath the glove compartment, near the center console. Looking up from the floor, you can see the arrow pointing to the buckles of the air conditioning filter—there are three in total. Gently pry them outward to open, and inside you will find the air filter. 2. Press firmly on the fixing buckles on both sides of the cover plate to remove it. Finally, pull out the old air conditioning filter and insert the new one. The general replacement cycle for the air conditioning filter is every 10,000 kilometers.
