What is the appropriate tire pressure for car tires?

Car tires should have the following appropriate tire pressure: 1. The front tires should have a pressure of 2.2 to 2.3 bar when unloaded and 2.4 to 2.5 bar when fully loaded; 2. The rear tires should have a pressure of 2.4 to 2.5 bar when unloaded and 2.6 to 2.8 bar when fully loaded. The recommended tire pressure range may vary depending on the tire model, and the standard tire pressure for the vehicle is usually indicated by the manufacturer. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its failure can lead to the end of the car's life. Tire pressure is like the blood pressure of the car, and its level plays a crucial role in the car's performance and power.

Why can't the remote key lock the car door?

The reason why the remote key cannot lock the car door is that insufficient battery power in the remote key can lead to unstable circuit performance and a shortened wireless communication distance, resulting in the phenomenon of the car door not locking. This issue can be resolved by replacing the battery. Both the infrared remote sensing and short-range wireless radio frequency circuits of the remote key are prone to failure, and these two methods are susceptible to interference from high-power devices, which can cause the key light to flash but fail to lock the door. The remote key utilizes the wireless remote control function of the central locking system, allowing the door to be opened or locked from a distance without inserting the key into the lock. The principle involves the key emitting a weak radio wave, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator performs the action of opening or closing the lock.

How to Tell When Tires Need Replacement?

Methods to determine when tires need replacement: 1. Check the degree of tire wear. A simple method is to observe the markers in the longitudinal grooves of the tire tread. These markers indicate a height of 1.6 millimeters. When the remaining groove depth of the tire tread reaches or falls below 1.6 millimeters, it's time to replace the tires. 2. Consider the time or mileage. 3. Look for any abnormalities in the tires. Tires are round, elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. They support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning capabilities.

Where is the trunk switch on the Cruze?

The Cruze does not have an interior trunk switch; it can only be opened manually by pressing the switch on the back of the trunk or by using the remote control. Hold the remote control button to open the trunk. The Cruze has relatively low fuel consumption and its performance is among the best in the A-class segment. Currently, it is available in 6 models with either a 1.6 or 1.8-liter engine. The wheelbase of the Cruze is deliberately widened, with the front and rear wheels positioned at the outermost edges of the sleek body, giving it a wider and more sporty proportion than most mainstream competitors. The compact and precise body gaps, along with the minimal use of additional decorative elements, further highlight the Cruze's high-quality and trend-leading exterior design.

What does the departure angle of a car mean?

Car departure angle refers to the angle between the tangent line drawn from the rear protruding point of the car to the rear wheels and the road surface when the car is fully loaded and stationary. It is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the vehicle's rearmost wheel tire. Any rigid component fixed behind the rearmost wheel must not be below this plane. The departure angle of a car is an evaluation index of its off-road capability. The larger the departure angle, the greater the possibility that the car will not collide when leaving obstacles such as small hills or ditches, indicating better off-road performance. Different cars have varying angles, which significantly affect driving performance. When a car is going downhill, if this angle is smaller than the slope, it may cause the lower rear protruding parts of the car to hit the slope surface, resulting in damage to the car.

What are the signs of damage to the front wheel bearings of a sedan?

The signs of damage to the front wheel bearings of a sedan are: 1. A loud humming noise is heard after the car is driven; 2. The temperature rises because the damaged front wheel bearings increase friction, generating a lot of heat, and the area will feel hot to the touch; 3. When the car is lifted with a jack and the tire is shaken, there will be play. The main function of the bearings is to bear the load and provide precise guidance for the rotation of the hub. They bear both axial and radial loads, making them a very important component. The wheel bearings in traditional cars are composed of two sets of tapered roller bearings or ball bearings combined. The installation, greasing, sealing, and adjustment of the bearing clearance are all carried out on the automobile production line.
