Car Engine Serpentine Belt Replacement Interval: The engine serpentine belt should be replaced when the vehicle reaches 60,000 kilometers or after 1-2 years of use. Below are the hazards of not replacing the engine serpentine belt: 1. Belt Breakage: If the belt breaks, it usually starts with some cracks or becomes extremely hard due to aging. Without proper maintenance, the belt may lose teeth, and the engine may experience skipped teeth. In severe cases, the belt can snap directly, affecting the normal operation of the vehicle. 2. Piston and Valve Collision: If the belt breaks, due to its own inertia, the camshaft will continue to operate. However, without the coordinating function of the belt, the piston and valves will operate freely and out of sync, leading to continuous collisions. In severe cases, both components may suffer damage.

Where is the ambient light switch for the Avancier?

The Avancier does not have an ambient light switch. The ambient lights automatically illuminate when the vehicle is powered on, and they are single-color lights. Ambient lighting serves as decorative illumination, typically in red, blue, or green, enhancing the cabin's aesthetics at night. However, if the lights flash too rapidly or are overly bright, they may distract the driver and pose a safety hazard. In terms of interior design, the Avancier retains Honda's distinctive style while featuring a symmetrical dashboard wrapped in soft materials and wood-grain accents. A large, adjustable-angle floating touchscreen is positioned at the center, elevating the technological ambiance of the cabin.

Reasons for Feeling Unable to Stop When Braking Hard?

Reasons for being unable to stop when braking hard are as follows: 1. ABS system activation: Even with ABS activated, the vehicle shows no significant braking effect, and the braking distance noticeably increases. 2. Wheels not locking up: ABS does not activate, and the vehicle continues to roll forward. For the first issue, the problem likely lies with the tires. Possibly, the tires are severely worn, leading to a reduced static friction coefficient, which causes the tires to lock up too easily and triggers ABS intervention prematurely, failing to generate effective braking force and compromising safety. 3. Solution: Replace the tires. It is recommended to switch to a slightly larger tire size for a significantly improved braking effect. As for the second issue, the problem likely originates from the braking system itself.

What is the Function of the Transmission System?

The function of the transmission system is to transmit the power generated by the engine to the driving wheels of the vehicle, thereby generating driving force and enabling the vehicle to travel at a certain speed. Off-road vehicles often employ four-wheel drive, which necessitates the inclusion of a transfer case in the transmission system. The components of a vehicle's transmission system include the gearbox, main drive shaft, intermediate bearing, front and rear axles, and wheel differential. The power produced by the vehicle's engine is transmitted to the driving wheels through the transmission system. The transmission system performs functions such as deceleration, speed change, reversing, power interruption, inter-wheel differential, and inter-axle differential. Working in conjunction with the engine, it ensures the vehicle operates normally under various conditions, delivering excellent performance and fuel efficiency.

What is a VIN?

VIN (Vehicle Identification Number) is a unique code assigned by the manufacturer to identify a vehicle. It consists of a 17-character alphanumeric sequence, also known as the 17-digit identification code, chassis number, or 17-digit number. The arrangement of the VIN ensures that no two vehicles of the same model will have the same number within 30 years, providing unique identification for each vehicle. The meanings of the VIN digits are as follows: 1. The first digit represents the country or region of manufacture; 2. The second digit indicates the car manufacturer code; 3. The third digit denotes the vehicle type code; 4. Digits 4 to 8 represent vehicle characteristics; 5. The ninth digit is a check digit; 6. The eleventh digit indicates the assembly plant; 7.
