Honda D gear flashing indicates a malfunction in the automatic transmission, which causes the D gear light to blink. Common Honda faults can be categorized into two types: 1. The fault light is on, but the car shows no abnormal symptoms while driving: This is usually a fault in the mechatronic unit, typically involving issues with the transmission computer or sensors. The repair solution involves fixing the damaged components or replacing them. 2. The fault light is off: The vehicle may exhibit abnormal noises or slipping while driving. Abnormal noises are generally caused by wear on the input/output shafts or pressure cylinders, while slipping is usually due to surface burns on the pressure cylinder or chain wear.

What are the body dimensions of the Guangzhou Honda Vezel?

The length, width, and height dimensions of the Guangzhou Honda Vezel are 4340mm/1790mm/1605mm, which are official data. The length of the Guangzhou Honda Vezel refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The naturally aspirated engine of the Guangzhou Honda Vezel has a maximum power of 96kW and a maximum torque of 155 Nm. This engine reaches its maximum power at 6600 rpm and its maximum torque at 4600 rpm. It is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. This engine is paired with a continuously variable transmission (CVT). The state has relevant regulations regarding vehicle dimensions. According to the national standard 'GB1589-89', the total width of a vehicle does not include the rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, under national standards, the significance of vehicle width data lies in ensuring enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

What does an exclamation mark on the dashboard mean?

An exclamation mark on the dashboard can indicate three different situations: An exclamation mark inside a circle with brackets: Brake pad damage or insufficient brake fluid. The solution is to release the parking brake and check if the brake fluid is low. If the light remains on, go to a repair shop to replace the brake pads. An exclamation mark inside a triangle: External light malfunction. The solution is to check if the lights are faulty. If there is no issue but the light remains on, it is recommended to visit a repair shop for maintenance. An exclamation mark inside yellow brackets: Issues with tire pressure in one of the tires. The solution is to check if the tire is punctured or leaking air. If not, drive at low speed and look for an auto repair shop, car care center, or roadside car wash, as they usually have air pumps. Inflate the tire and observe the dashboard again. If the warning light still doesn't turn off, locate the settings in the vehicle's central console and perform another tire pressure check. The light will turn off once the pressure is normal.
