Should an automatic transmission car be started in P gear or N gear?

An automatic transmission car should be started in N gear. The specific explanations are as follows: 1. When starting the car, shifting from P gear to D gear will pass through R gear, which will cause a reverse impact on the transmission and damage it. Over time, the damage can be significant. 2. The correct method is to turn on the power, press the brake, shift to N gear, then start the engine and shift to D gear. 3. Starting the engine in any gear other than P or N gear, although the engine will not run (due to the interlock protection mechanism, it can only be started in P or N gear), may burn out the neutral start switch of the transmission. 4. The automatic transmission is equipped with a neutral start switch, which ensures that the engine can only be started in P or N gear, preventing the car from suddenly moving forward if started by mistake in other gears.

As a driver with years of experience in automatic transmission vehicles, I always recommend starting the car in P (Park) gear. This is not only safe but also aligns with standard operating procedures. The P gear is the parking position, which locks the wheels when starting, preventing the car from moving unexpectedly. On the other hand, N (Neutral) gear is the free position without any locking function. If you accidentally press the wrong pedal or if the road has a slope, the car could roll away, posing a significant risk. Once, I tried starting the car in N gear in a garage, and when I released the brake, the car lurched forward a short distance, nearly hitting the wall. Since then, I only use P gear. Developing this habit is simple: step on the brake as soon as you get in the car, confirm the gear is in P, and then start the engine. This also helps prolong the lifespan of the transmission, so there's no need to take unnecessary risks. Remember, safety comes first—don't be misled by so-called quick-start methods.

How to Loosen the Negative Terminal of a Car Battery?

Here are the steps to loosen the negative terminal of a car battery: 1. Unscrew the two fastening buttons of the heat insulation cover, then lift the red and black insulation caps on the positive and negative terminals (red for positive, black for negative). 2. Use a wrench to loosen the fastening nut on the negative terminal of the battery, then gently pry open the fastening block with a flat-head screwdriver to remove the negative terminal. Here is some related information about car batteries: 1. The negative terminal of the car is connected to the car body, which is made of metal. The entire car body acts as the negative terminal, meaning the car body itself can be considered the negative terminal. 2. Most disassembly tools are made of metal. If a metal tool touches a metal part of the car body, the positive and negative terminals may directly connect, forming a circuit. This can cause the electrode to melt, potentially damaging the battery or even leading to a fire.

How to open the front hood of a Mercedes-Benz e300?

Mercedes-Benz e300's front hood is opened using a dedicated switch, which is located on the knee guard panel of the driver's seat. It is a red handle. The functions of the car's front hood are as follows: 1. Protect the engine: The front hood can effectively prevent the car engine from being exposed to wind, sun, and rain, and also prevents foreign objects from hitting and damaging the engine during high-speed driving. There are many and complex parts in the car's engine compartment, so the protective role of the front hood is very important; 2. Airflow guidance: The design of the front hood complies with aerodynamics, reducing the resistance of the car's movement through airflow guidance, and also improving the car's stability; 3. Protect the safety of passengers: When the car engine boils or combusts, it can effectively isolate the impact force generated by the engine, protecting the safety of passengers to a certain extent.

Does the 90-second parallel parking time include the entry time?

The 90-second parallel parking time does not include the entry time. Timing starts when the vehicle enters the parallel parking area and ends when it exits the area. Timing begins when the vehicle enters the parallel parking test area and ends when it exits the area. The time is calculated from the moment the vehicle enters the parallel parking test zone until it exits, with a maximum allowed interval of 90 seconds. The parallel parking zone starts 4 meters before the parking space and has a total length of 17.7 meters, with the parking space itself being 7 meters long and 2.5 meters wide. The test is considered complete once the vehicle exits the stop line after successfully parking. With proper technique, the maneuver can be completed in half the allotted time. To maintain a 30cm distance from the lane line, use the node on the windshield wiper as a reference point to align with the line. For steering timing, observe the right rear wheel center and the left front corner of the parking space in the right rearview mirror—when the wheel center reaches the corner, quickly turn the steering wheel one full turn to the right. To straighten the wheels, watch the left rearview mirror and return the steering wheel to center as soon as the right rear corner of the parking space becomes visible. Failing criteria include the vehicle body crossing the line after parking, not using or incorrectly using turn signals when exiting (10-point deduction), exceeding the 90-second time limit (failure), the vehicle body touching the parking space boundary lines during movement (10-point deduction per occurrence), wheels touching the lane boundary lines (10-point deduction per occurrence), and stopping for more than 2 seconds during the maneuver (5-point deduction per occurrence).

What are the best tires for the GS4?

GAC Trumpchi GS4 uses Michelin PRImACY tires, with the models being 225/60R17 and 225/55R18. Michelin was founded in 1889 in Clermont-Ferrand, France. Over more than 100 years, Michelin has undergone continuous innovation and development. It now operates businesses across five continents and has R&D centers in Europe, North America, and Asia. Michelin tires are marketed in over 170 countries worldwide. For the GAC Trumpchi GS4 tires in daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves of the tires gradually become shallow. If the tread wears flat, it will lose its drainage and anti-skid functions, significantly reducing the car's performance. Small cracks may seem minor but can be a hidden danger for tire blowouts at high speeds. Additionally, promptly remove pebbles stuck in the grooves. Try to park on level ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, the driver should not turn the steering wheel, as this action accelerates tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure increases. In such cases, stop to let the tires cool down naturally. Never release air to reduce pressure or splash water to cool them, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or emergency braking to prevent accelerated tread wear due to dragging between the tires and the ground.
