To Which Position Should the Car Rearview Mirrors Be Adjusted?

Here are the positions to which the car rearview mirrors should be adjusted: 1. Left rearview mirror. The driver should use the horizon as a reference, adjusting the vertical angle so that the sky and ground each occupy half of the mirror. Adjust the horizontal angle so that the car body occupies about 1/4 of the mirror surface. Note that the adjustment should be made based on the driving posture, not by leaning closer to observe the mirror. 2. Right rearview mirror. Since the right rearview mirror is the farthest from the driver's position, the space occupied by the sky should be reduced. Therefore, the sky should occupy only 1/4 of the right rearview mirror, and the car body should also occupy 1/4. 3. Central interior rearview mirror. Through this mirror, the driver should be able to see the situation behind the car through the rear window, with the ground and sky each occupying half of the view.

What are the symptoms of a broken turbocharger?

When the engine turbocharger is broken, the following symptoms may occur: 1. Decreased vehicle power. 2. Incomplete fuel combustion. 3. Severe carbon buildup in the engine. 4. Increased fuel consumption. 5. Blue or black smoke from the exhaust pipe. 6. Engine shaking. 7. Harsh noises during sudden acceleration. Below is extended information on the causes of engine turbocharger damage: 1. Blue smoke during driving or acceleration indicates poor sealing of the turbocharger impeller shaft. 2. Increased fuel or oil consumption suggests severe blockage in the engine's exhaust gas recirculation pipe. 3. Abnormal engine noises during driving may be due to worn or aged piston rings, cylinder walls, or valve seals. 4. Abnormal noises during throttle application or release could indicate a cracked turbocharger air duct.

What is the general speed limit in highway tunnels?

Highway tunnels typically have a speed limit of 60 to 80 kilometers per hour. Lane changing and overtaking are prohibited in tunnels due to limited space and poor lighting conditions, which can easily disrupt normal traffic flow. Moreover, most tunnels are equipped with comprehensive camera surveillance systems. Illegal lane changes will result in a 3-point penalty and a fine of 150 yuan. Below are precautions for driving in tunnels: 1. When drivers see they are approaching a tunnel, they should check the speed limit signs on both sides of the road in advance. If using navigation, it usually provides early warnings about tunnel speed limits, at which point drivers should slow down and maintain a safe distance from vehicles ahead. 2. Before entering a tunnel, drivers must turn on their headlights and keep them on until completely exiting the tunnel. The sudden darkness upon entering can cause temporary visual impairment as eyes struggle to adapt to the abrupt change in lighting. Turning on headlights beforehand helps mitigate this visual shock. 3. Lane changing, U-turns, and tailgating are prohibited in tunnels. When exiting, drivers should gradually reduce speed to allow their eyes to adjust to the bright outdoor light. Conspicuous warning signs are posted above or beside tunnel entrances—drivers must strictly follow regulations as all tunnels have 24/7 video surveillance with zero tolerance for violations.

What are the symptoms of a broken steering gear in a large truck?

The following are the symptoms of a damaged steering gear in a large truck: 1. Oil leakage from the steering gear. 2. Abnormal noise when turning the steering wheel. 3. A 'click' sound when turning the wheel to the extreme and returning. 4. Heavy steering wheel. Below are the causes and solutions for steering gear malfunctions: 1. Power steering pump failure. When the pump pressure of the power steering pump fails to meet the standard value, it is evident that the heavy steering is related to this. Check whether the mating surface of the flow control valve and the valve seat is not tightly sealed, and whether the safety valve steel ball is not properly closed. 2. Steering gear failure. If the inspection reveals that the hydraulic pressure of the steering gear is low, it indicates that the heavy steering is caused by the steering gear. In this case, professional manufacturers should be consulted for repair. Most steering gear failures are caused by scratches on the piston or cylinder barrel, or damage to the piston seal ring, which allows the two chambers of the piston to communicate, preventing the effective establishment of assist pressure. 3. Lack of oil or air in the system. If the power steering system lacks oil, causing air to enter the system, not only will the steering feel heavy, but there will also be noise during steering. In this case, simply follow the oil filling and air bleeding procedure to remove the air.

How to Adjust Electric Rearview Mirrors?

In the electric rearview mirror adjustment knob, L represents the left rearview mirror, and R represents the right rearview mirror. The following are the steps to adjust electric rearview mirrors: 1. The driver sits in the driver's seat and locates the electric adjustment knob on the left door. 2. Observe the white dot on the adjustment knob and the letters beside it. To adjust the angle of the left rearview mirror, rotate the knob's white dot to the L position. (To adjust the right rearview mirror, rotate it to the R position). 3. Then lift the knob upward to change the mirror's viewing angle upward. Similarly, pressing the knob downward changes the viewing angle downward. For left and right adjustments, use the same method of tilting the knob. Below is additional information on electric rearview mirror adjustment: 1. When adjusting the viewing angle of electrically adjustable rearview mirrors, it can be done via the electric buttons inside the car. 2. The buttons are generally designed on the left side of the steering wheel and can adjust both left and right rearview mirrors. When driving on narrow roads, the mirrors can be folded to improve the car's maneuverability.

How to Push-Start a Manual Transmission Car?

Below are the steps for push-starting a manual transmission car: 1. Before pushing, turn the key to the ON position to power up the vehicle without manually cranking the ignition. 2. Then depress the clutch pedal and shift into second or third gear. 3. When the pushing speed reaches about 10km/h, release the clutch while gently applying throttle. 4. Once the engine shows signs of starting with operational sounds, quickly depress the clutch, shift to neutral, and control the throttle properly to complete the startup. Precautions for push-starting a manual transmission car: 1. This method is typically used when the battery has insufficient charge due to circuit shorts during driving or damaged wiring, making it unable to restart after stopping. Push-starting is the simplest and most convenient solution but requires certain conditions; use this method if circumstances permit. 2. Pushers must ensure safety—the vehicle should be on flat ground with adequate speed distance, and the pushed vehicle must have functional brakes. 3. Applicable scenarios: When the vehicle lacks power or has insufficient power.
