When the tachometer and coolant temperature gauge reach the leftmost mark, it indicates that the engine has reached the optimal starting temperature. The tachometer reaching the normal value also signifies that the vehicle has been properly warmed up. Generally, the engine idles at around 800 RPM in summer, while in winter, it idles at approximately 1200 RPM. At this point, it depends on the local temperature. If the engine RPM drops to around 800, it means the vehicle is ready for normal driving. This refers to whether the engine's cooling system is functioning properly. The coolant temperature gauge consists of a pointer, scales, and the letters C and H.

At What Height Does a Child Count as a Seat in a Private Car?

Children over 1.2 meters in height count as a seat. Children under 12 years of age are not allowed to sit in the front passenger seat when traveling in a car and must sit in the rear seats. Children under 4 years of age must use a safety seat when riding in a car, and children under 7 years of age can use a three-point seat belt in conjunction with a child seat. More relevant information is as follows: Note 1: Children are naturally active, and the car's center console, gear lever, and handbrake may all be objects that children play with, which undoubtedly increases the risk factor of driving. If a child sits alone in the front passenger seat, they may collide forward like a bullet during an emergency brake, leading to severe injury or death. Note 2: Allowing a child to stick their head out of the sunroof while the vehicle is in motion can risk injury to the child's neck and ribs if the vehicle brakes suddenly. Additionally, many vehicles have an automatic window and sunroof closing function after the engine is turned off. If the child does not retract their head in time, the closing sunroof may trap their head. Note 3: Do not let children get in and out of the car by themselves. Note 4: Do not place too many decorations or toys in the car.

Why Did I Fail the Straight-Line Driving Test in Subject 3?

Unstable steering control, inability to maintain straight-line driving; failure to promptly take deceleration measures when encountering braking by the vehicle ahead; riding or pressing the solid center line or edge line of the lane during driving; inaccurate control of the vehicle's direction, with steering wobble and deviation from the correct path; prolonged riding or pressing the lane dividing line while driving. Relevant explanations are as follows: 1. Timely correction: Unstable steering control does not mean not moving the steering wheel. When a vehicle is driving on the road, it is impossible to always go straight; the vehicle will inevitably have an angle and gradually deviate from the lane. Therefore, during driving, it is essential to correct the direction promptly, using minor adjustments to the steering wheel. 2. Reasons for failure: If you hesitate to adjust the steering wheel, you will miss the opportunity to correct. By the time the vehicle's deviation angle becomes significant, any steering adjustment will be too large, leading to failure, or being too close to the lane line will also result in failure.

Why is water dripping from the Golf's exhaust pipe?

Golf's exhaust pipe dripping water is a normal phenomenon. Here are the relevant explanations: 1. When gasoline mixes with air and ignites, it produces water vapor. The water vapor condenses into water droplets upon encountering cold temperatures, hence water drips from the exhaust pipe. 2. When the exhaust pipe heats up due to the car's operation, it evaporates the existing liquid water, resulting in white mist. This is why some cars have water dripping from the exhaust pipe while others emit white smoke, with the latter being more noticeable in winter. 3. If black smoke appears at the tail of the exhaust pipe, it may indicate severe carbon buildup inside the engine, leading to incomplete combustion of gasoline. In such cases, it's necessary to clean the carbon deposits.

Where is the Bora's water temperature gauge located?

The Bora's water temperature gauge is located in the center of the instrument panel. More information about the water temperature gauge is as follows: 1. When the water temperature warning light comes on, it indicates that the car's engine is overheating. You should stop and turn off the engine, wait for a while until both the water temperature and engine temperature drop before continuing to drive. Generally, the warning light won't come on unless the car is driven for an extended period or there is an issue with the vehicle itself. When the engine is operating normally, the water temperature gauge typically reads around 90 degrees. 2. The water temperature warning light is normally yellow. If the water temperature exceeds the limit, the light will turn orange and eventually red.
