Commercial vehicles refer to vehicles engaged in commercial road transportation. They are categorized into commercial road transportation and non-commercial road transportation. Below are the operating conditions for commercial vehicles: The vehicle should be clean and well-equipped, with bolts and nuts on exposed parts securely fastened, and the vehicle's power performance should be good. The engine should operate well, with normal fuel and lubricant consumption. There should be no knocking noises when the coolant temperature is above 50°C, and no leaks of oil, water, gas, or electricity. The chassis components should be securely connected, not overheating or making abnormal noises, with good performance. All lubrication points should have sufficient oil; the leaf springs should not be broken or misaligned; tire pressure should be normal; the connection and protective devices for the tractor and trailer should be complete and reliable. The steering should be light and flexible, with the tie rods and ball joints not loose, and performance should be good. The front wheel alignment should meet requirements, the foot brake effectiveness should comply with regulations, the hand brake should be reliable, and the trailer brake system should be effective. The passenger compartment or truck cab should be free of dust and rain leaks, with doors and windows tightly closed and easy to open. The windshield should provide clear visibility. The cargo box should have no holes, and the tailgate hooks should be secure and reliable. Electrical equipment should be complete and function reliably.

What is the suitable tire pressure for Civic in summer?

The recommended tire pressure for Honda Civic in summer is between 2.3-2.4 bar. The normal tire pressure range for Civic is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The indicator for Honda Civic's tire pressure monitoring system is a semi-enclosed exclamation mark symbol on the car dashboard, which is enabled by default and does not require manual activation. However, under normal circumstances, Civic's tire pressure monitoring system does not display or allow access to specific tire pressure data. It only shows abnormal tire pressure when there is an issue. Generally, a tire pressure above 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening its lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing excessive rolling and abnormal heat generation; reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; exponentially increases friction between the tire and the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator lights up (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 triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, the tire pressure monitoring system was not reset in time, causing it to still record the previous data, which triggers the indicator. Simply reset the tire pressure monitoring system. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors tire pressure. If the sensor is damaged due to impact while driving, it will also trigger the tire pressure warning light. For sensor damage, replacement with a new part is the only solution.

Where is the rear wiper switch for the Tiguan L?

Tiguan's rear wiper switch is located on the wiper lever on the right side of the steering wheel, together with the front wiper. Push or pull the lever to control the rear wiper. Relevant information about the wiper is as follows: 1. Introduction: The wiper, also known as the windshield wiper, is a device used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and increasing driving safety. 2. Usage: On rainy days, when raindrops fall on the windshield, the view ahead is quickly obstructed, and vehicles, pedestrians, and scenery become blurred. At this time, turning on the wiper will restore a clear view ahead.
