What is the appropriate tire pressure for the Haval Big Dog?

The normal tire pressure range for the Haval Big Dog is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data is based on the requirements and standards of the international GBT2978-2008. The Haval Big Dog is equipped with a tire pressure monitoring function. After starting the car, you can access the tire pressure monitoring function via the settings button on the steering wheel to check the specific tire pressure values. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; increased body vibration indirectly affects the lifespan of other components; it causes excessive stretching and deformation of the tire cords, reducing the tire's elasticity and increasing the load on the car while driving. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, among other factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; it reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; the friction between the tire and the ground multiplies, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, an alarm will sound if the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator light to come on. Simply resetting the tire pressure will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation port. If the sensor is damaged due to impact while driving, the tire pressure warning light will also come on. For sensor damage, the only solution is to replace it with a new part.

How to Deal with Water Ingress in Car Radar?

First, use a dry cloth to clean the lens surface of the camera, then use a hair dryer to blow air at the camera for a few minutes. If the water ingress is caused by poor sealing of the camera, it is best to remove the camera and dry it thoroughly. If moisture has penetrated into the internal components of the camera and the hair dryer is ineffective, then it is necessary to go to a repair shop for a replacement.

How to Deal with Scratches on Black Plastic Car Bumper?

Lightly sand the scratched area with wet sandpaper to thoroughly remove dirt, ensuring complete cleanliness. After cleaning the dirt, apply the touch-up pen paint on paper to match the color with the car body. Wipe the area to be touched up clean with a cleaning pad. Unscrew the upper part of the touch-up pen cap and apply the paint evenly with the brush, applying thin layers—about 2-3 layers should suffice.

How to Fix Detached Car Interior Fabric?

Purchase a specialized automotive adhesive or bonding product, apply the glue along the detached edge, let it dry for 3-5 minutes, and then press it back into place. Alternatively, you can use clips for repair by selecting clips that match the color of the interior. The downside is that it may not look as aesthetically pleasing, but it is a practical solution. Another method is to prepare a new piece of headliner fabric along with specialized headliner adhesive. Apply the adhesive to both surfaces, let it dry for 3-5 minutes, then press them together and reinstall the headliner.

What to Do When Your Car Battery Dies: How to Use an Emergency Power Source?

First, open the car's hood and ensure the support rod securely holds it in place. Locate the battery, then correctly attach the clamps to the positive and negative terminals. Make sure they are firmly connected and not reversed. Activate the starting port of the 'Dian Jiang Jun' car emergency jump starter, then insert the blue connector of the battery clamps into the ignition interface. Double-check that the battery clamps are secure and the polarity is correct. Enter the driver's seat and turn the key to start the engine (some vehicles may have a push-button start).
