When encountering a red light with an automatic transmission, the following stopping measures can be taken: 1. For short red lights, you can simply press the brake pedal. 2. For long red lights, shift to N gear and engage the handbrake. If the stopping time exceeds 2 minutes, you should shift to N gear to protect the transmission and prevent the transmission fluid from overheating. If the stopping time exceeds 5 minutes, it's best to turn off the engine, shift to P gear, which is both environmentally friendly and fuel-efficient. The starting steps for an automatic transmission are: 1. Insert the key and turn it to the second power position (ignition), wait for the system self-check to complete. 2. Shift the gear lever from P gear to N gear. 3. Release the brake and start the car's engine. 4. Press the brake pedal with your foot, shift the gear lever from N gear to D gear, release the brake and press the accelerator to start. Driving precautions for automatic transmissions include: 1. Start with gentle acceleration, shift to P gear or N gear when starting, and avoid coasting in neutral. 2. Shift back to N gear when waiting at a red light or briefly stopping, and shift to P gear when parking. 3. Do not shift into P gear while driving. 4. Ensure the vehicle is completely stopped before shifting into R gear for reversing.

Since I started learning to drive, I remember my instructor taught me to slow down in advance when encountering a red light and maintain a safe distance. Gradually press the brake pedal to bring the car to a smooth stop—never brake suddenly to avoid rear-end collisions. For automatic transmissions, just stay in D gear; no need to shift, so you can start moving as soon as you lift your foot. When I first started driving, I was always worried about rolling back or damaging the transmission, but after a few years, I found this method the most hassle-free and without wearing out parts. If the light stays red for a long time, I sometimes shift to P gear and pull the handbrake to rest my foot, but for short waits, just stay in D gear and hold the brake firmly. Practice a few times, and it’ll become much easier once you’re used to it. Remember, safety first—don’t get distracted by your phone.

What is the fuel consumption of the CHR?

The fuel consumption of the CHR is 4.5L-5.7L. Reasons for increased fuel consumption: Displacement: The engine displacement has a certain impact on the car's fuel consumption, but this impact is a fixed value. Tire pressure: The car's fuel consumption is also directly related to tire pressure. When the tire pressure is too high or too low, the car's fuel consumption will increase. Road conditions: The road conditions on which the car is driven also affect fuel consumption. Methods to reduce fuel consumption: Start slowly, avoid sudden acceleration, shift gears at low RPMs, avoid flooring the accelerator, do not compete with others at traffic lights, repair any dents on the car body, close windows at high speeds to reduce drag, coast in high gear (never coast in neutral as it can lead to steering and brake failure), and remember that driving habits can make a big difference. Drive safely: do not drive under the influence of alcohol, do not drive while fatigued, do not exceed speed limits or overload, and always wear your seatbelt.

Is it necessary to fasten seat belts in the back seat on the highway?

It is necessary to fasten seat belts in the back seat on the highway. Here are the relevant details: 1. The function of seat belts is: in the event of a vehicle collision or when emergency braking is applied, the pre-tensioning device will instantly tighten the slack seat belt, firmly securing the occupant to the seat to prevent secondary collisions. 2. Precautions for driving on the highway include: car drivers and front-seat passengers should fasten their seat belts, drivers should not make phone calls, avoid sudden steering wheel movements at high speeds, lanes should not be changed arbitrarily while driving, turn signals must be activated in advance when changing lanes or overtaking the vehicle ahead, only adjacent lanes are allowed for overtaking and drivers should immediately return to the driving lane after overtaking, vehicles must not ride or press on lane dividers, must not reverse or drive in the opposite direction, must not cross the central divider to make U-turns or turns, must not conduct test drives or drive training vehicles, must not overtake, stop on ramps, maintain a driving distance of more than 100 meters, and when the speed is below 100 kilometers per hour, the distance from the vehicle ahead in the same lane can be appropriately shortened, with a minimum distance of no less than 50 meters.

BYD Han: Should I Use 95 or 92 Octane Gasoline?

According to the official vehicle manual recommendation, the BYD Han should use 92 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, the BYD Han's fuel cap also indicates the recommended octane rating. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is even higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade—high compression ratio engines can also be tuned to use lower octane gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the BYD Han occasionally uses the wrong gasoline grade, simply switching back to the correct grade after consumption is sufficient. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using a higher octane grade will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using a lower octane grade can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues. The vibrations not only affect driving stability but also cause abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.

Where to Find BMW PIN Code?

BMW PIN code can be obtained by consulting the corresponding 4S dealership based on your specific vehicle model. Here is relevant information about the vehicle PIN code: 1. The vehicle's PIN code is generated from the car's identification number, the 17-digit VIN (which contains manufacturer information and vehicle details). Only the manufacturer can calculate it, and each vehicle corresponds to only one unique 8-digit PIN code. 2. As the production identification code of the car, the PIN code primarily ensures the vehicle's security. It is required for programming car keys.

What Are the Possible Causes of Vibration After Installing New Tires?

Here are several reasons for car vibration after installing new tires: 1. Improper wheel alignment and balancing: If there is slight vibration after installing new tires, it is usually caused by improper wheel alignment and balancing. In this case, you can contact the 4S shop as soon as possible to have it redone. 2. Deformed tire rims: If there is severe body vibration after installing new tires, it is likely caused by deformed tire rims. In this case, you should promptly visit a 4S shop for inspection and replace the tire rims with higher-quality ones, otherwise it may lead to traffic accidents.
