How to Replace the GS4 Cabin Air Filter?

Here is the method for replacing the GS4 cabin air filter: 1. First, open the glove box cover of the Trumpchi GS4. Locate the fixing clip on the right side of the glove box and pull it outward firmly; 2. Remove the glove box. After removal, you will see the cabin air filter cover. Press the fixing clips on both sides of the cover firmly, and the cover can be removed; 3. Finally, pull out the old cabin air filter to the side and install the new one. The functions of the cabin air filter are as follows: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., providing strong and long-lasting moisture adsorption. 4. It prevents the car windows from fogging up, ensuring clear visibility for the driver and passengers and safe driving. It provides fresh air to the cabin, preventing the inhalation of harmful gases and ensuring driving safety. It also has strong antibacterial and deodorizing effects. 5. It keeps the cabin air clean and free from bacterial growth, creating a healthy environment. It effectively separates solid impurities such as dust, core powder, and abrasive particles from the air and intercepts pollen, ensuring that the driver and passengers do not suffer from allergic reactions that could affect driving safety.

How to Lift Up the Rear Seats of Haval M4?

Here is the method to lift up the rear seats of Haval M4: On both sides of the rear seats, there is a switch near the headrest. Press the switch and push it forward to fold the seatback. Open the rear trunk, and underneath the seats (if not visible, it might be pressed under the seat), there is a black strap. Pull the strap backward and lift the seat upward. For more details about the Haval M4: 1. In terms of exterior dimensions, the Haval M4 can be considered a typical compact SUV. Looking at the domestic SUV market, it seems only the Haval M series has ventured into this niche SUV segment. With a ground clearance of 185mm and relatively large tire size, its off-road capability is evident. For consumers who desire an SUV but are concerned about urban parking difficulties, the Haval M4, as a compact SUV, might be an ideal compromise. 2. In terms of power performance, the Haval M4 is equipped with a self-developed engine by Great Wall—a 1.5L VVT all-aluminum engine. This engine is widely used in multiple products under the Great Wall brand, and its mature reliability is beyond doubt. With 78kW and 139N·m, it should be more than sufficient to drive this small vehicle. Four-wheel disc brakes are uncommon in this class, and although the rear longitudinal arm torsion beam composite suspension is a semi-independent suspension, it aligns well with the Haval M4's positioning.

What is the general cylinder pressure for cars?

Different car models have varying normal cylinder pressures. Generally, Japanese cars have around 1100KPa, while European and American cars are approximately 1200-1300KPa. Modern direct-injection engines tend to have higher pressures. A normal four-cylinder engine should have a cylinder pressure above 7 atmospheres. Below is some relevant information: Introduction to cylinder pressure: It refers to the compression force size when the piston reaches the top dead center at the end of the compression stroke. Hazards of insufficient cylinder pressure: It can lead to decreased fuel efficiency, insufficient power, increased fuel consumption, and excessive engine temperature; increased carbon deposits, severe engine shaking; lubricating oil entering the combustion chamber, causing oil burning; black smoke from the exhaust pipe, reduced engine lifespan, and premature vehicle failure.

Is Overinflated Tire Pressure Prone to Blowouts?

Tire pressure that is too high can indeed lead to blowouts, as tires are rubber products with certain load limits. Here is an introduction to tire pressure: 1. Different types of tires have varying load limits. Generally, high-performance tires have higher limits. 2. The standard range for car tire pressure is often indicated on the fuel tank cap. Typically, the normal tire pressure for passenger cars is around 2.5 bar. If the tire pressure exceeds this value, it can have adverse effects. When the pressure is too high, the tire's grip decreases, leading to reduced vehicle handling. Especially in summer, the car may experience skidding, significantly compromising driving comfort.

How to Shift Between D and S Gears in an Automatic Transmission?

While driving, you can directly shift from D gear to S gear in an automatic transmission car. It is also possible to engage S gear from D gear during acceleration. Here is an introduction to shifting from D to S gear in an automatic transmission car: 1. To switch from D gear to S gear in an automatic transmission car, there is no need to press the brake or come to a complete stop. The car can shift directly from D to S gear while in motion, and S gear can also be engaged during acceleration. After shifting to S gear, the power output becomes more intense, and fuel consumption increases accordingly, as power and fuel consumption are directly proportional. 2. For normal driving, D gear is generally used, as it has a very wide range of applications. In situations requiring higher power, S gear or sport mode can be used.

Can You Continue Driving with Engine Trouble?

Not all engine failures mean you can't drive; it requires case-by-case analysis. Here's an introduction to the engine warning light: 1. If the engine warning light is on but there are no abnormal noises in the engine compartment, no other warning prompts on the dashboard, the vehicle's power is unaffected, and the transmission's upshifting is normal, you can continue driving to the 4S shop for further inspection. Issues like intake and exhaust can also trigger the engine warning light. 2. There are two scenarios when the engine warning light is on: (1) Yellow symbol light. This indicates there is a fault in the engine, but it does not affect the engine's normal operation, though maintenance is needed. (2) Red symbol light. This signifies a serious engine fault that normally requires immediate repair. In special road conditions, you may drive temporarily, but you must constantly monitor the engine's working condition.
