What is the height of a four-axle vehicle in meters?

Why can't you turn on the air conditioning immediately after getting in the car?

In summer, turning on the air conditioner requires the engine to power the cooling system. A freshly started engine does not yet have sufficient power, and running the air conditioner may cause the engine to stall. In winter, the heating system utilizes the heat generated by the engine during operation. A cold engine has not yet produced enough heat, so turning on the heater at this stage is ineffective. Here are some reasons why a car's air conditioning may not cool properly: 1. Insufficient refrigerant in the car's air conditioning system. 2. Leakage of refrigerant in the car's air conditioning system. 3. The condenser in the car's air conditioning system is too dirty. 4. The desiccant in the dryer is saturated with moisture. 5. The air conditioning filter is excessively dirty. 6. Malfunction of the car's air conditioning compressor. 7. Internal damage to the car's air conditioning pump.

What is the difference between blue, white, and yellow parking spaces?

The differences between blue, white, and yellow parking spaces are as follows: Roadside parking spaces marked with solid blue lines are free for long-term parking, while dashed lines indicate time-limited free parking; Roadside parking spaces marked with white lines require payment, some are "free at night," and parking should be done according to roadside signs; Parking spaces marked with solid yellow lines are generally reserved for special vehicles (such as fire trucks). Here are some parking precautions: No parking in areas with no-parking signs: No-parking signs indicate that within the specified area, all vehicles are prohibited from parking temporarily or for a long time. No parking within yellow grid lines: Yellow grid lines indicate that parking is prohibited in this area for any reason. They are commonly found at intersections, entrances, and exits. Solid yellow lines: Parking is prohibited on roads with solid yellow lines. The length of the yellow line indicates the size of the no-parking area. No parking near bus stops: Parking is prohibited in areas such as bus stops, gas stations, emergency stations, and near fire hydrants.

How Many Degrees Should You Turn the Steering Wheel for a Left Turn?

Under normal driving speeds, the degree to which you turn the steering wheel depends on the actual road conditions. Here are some general guidelines: General situation: Typically, you should turn the steering wheel to the 4 or 5 o'clock position, which is approximately 150 to 160 degrees. The top of the steering wheel corresponds to the 0 o'clock (12 o'clock) position. Generally, you turn the wheel to the 4 or 5 o'clock position and then return it. It's usually not necessary to go to the 6 o'clock position (equivalent to half a turn or 180 degrees). Generally, for a left turn, you turn to the 4 o'clock position, and for a right turn, to the 5 o'clock position, because left turns are wider (large curve) and right turns are tighter (small curve). The above applies to normal intersections. At actual intersections, the narrower the road, the greater the degree of steering required. Extreme situation: If the intersection is so narrow that there is no bicycle lane, meaning the right side of the car is directly next to the curb, then it becomes a "90-degree turn," requiring you to quickly turn the steering wheel all the way until the car body is at a 45-degree angle, then return half a turn, and finally return a full turn.

Can You Drive Wearing Thick or Medium-Heeled Shoes?

Driving while wearing thick or medium-heeled shoes is not recommended. Here are the reasons: Reason: When pressing the clutch or brake, flat shoes with thin and soft soles do not hinder foot sensitivity, whereas high heels do. While driving, the movement and stopping of the car, the speed adjustments, and the operation of the clutch, brake, and accelerator pedals all rely on the feet. High heels generally come in three types: stiletto, wedge, and thick platform heels. Regardless of the pedal type, wearing any of these shoes while driving poses safety risks. Additionally, if there are floor mats in the car, the heel of the shoe might pull the mat under the pedal, making it impossible to press. Safety hazards: Women's footwear varies widely, including not only high heels but also platform shoes, snow boots, and sandals. In hot weather, some even drive barefoot. Platform shoes, though different in style from high heels, pose similar risks while driving due to their thick, inflexible soles, which severely impair pedal feel and make it difficult to gauge pedal depth.

How many meters in advance should the turn signal be activated when turning?

Regulations have clear stipulations: When a motor vehicle turns, changes lanes, overtakes, makes a U-turn, or parks by the roadside on the road, the turn signal should be activated 100 to 50 meters in advance. The following are the relevant regulations for lane changing: 1. Lane changing must not affect other vehicles. The specific regulation is: On roads with two or more motor vehicle lanes in the same direction, the motor vehicle changing lanes must not affect the normal driving of motor vehicles in the relevant lanes. 2. The turn signal must be activated in advance when changing lanes. When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal should be activated in advance; when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal should be activated in advance. 3. Frequent lane changing is not allowed. When a motor vehicle does not affect the normal driving of other vehicles, it may borrow or change lanes, but it must comply with the following four regulations: 1. Yield to vehicles in the borrowed lane. 2. Drive in order and do not change lanes frequently. 3. Vehicles that should drive in the slow lane are allowed to borrow the lane to overtake when it does not hinder the normal driving of vehicles in the fast lane, but they must return to the original lane immediately after overtaking. 4. When vehicles from both the left and right lanes change to the same lane, vehicles from the left lane must yield to those from the right lane (for example, on a one-way three-lane section of Tiyu Street, if the outermost and innermost vehicles both want to enter the middle lane, the outermost vehicle has priority). 4. Turn signals must be used when entering or exiting the highway. When a motor vehicle enters the highway from the ramp, it should activate the left turn signal and enter the lane without hindering the normal driving of vehicles already on the highway. When a motor vehicle exits the highway, it should activate the right turn signal, enter the deceleration lane, and exit after reducing speed.

Is it necessary to replace the filter when changing transmission fluid with a circulation machine?

When changing the transmission fluid in a car, it is not necessary to replace the filter. If the transmission fluid is changed without removing the oil pan, the filter cannot be replaced. Here are some relevant details: Transmission fluid replacement: Among car maintenance tasks, changing the transmission fluid is also a very important one. Generally, transmission fluid needs to be replaced every two years or after driving approximately 40,000-60,000 kilometers. However, there is a filter inside the transmission oil tank, and often when the transmission fluid is changed, the transmission fluid filter element is not replaced. Function of transmission fluid: During the use of a car, the mechanical metal parts inside the transmission will rub against each other, potentially generating some impurities and metal debris. The role of the transmission fluid filter element is to filter out iron filings, sediment, and other impurities from the transmission fluid, supplying clean transmission fluid to various components, thereby providing lubrication and cleaning functions.
