Shiftlock on a car refers to the gear shift lock device, whose main function is to lock the gear position to ensure no gear jumping or disengagement, thereby guaranteeing driving safety. Shiftlock prevents the transmission from malfunctioning and being unable to move the gear; pressing it allows for forced movement. The method to use the shift lock release device is: 1. Press the car's brake pedal; 2. Press the car's one-touch start button; 3. The car's dashboard lights up, and the vehicle starts; 4. Press the gear shift lock button on the car's gear lever; 5. Push the car's gear lever to the desired position; 6. Press the car's accelerator pedal to move the vehicle.

When I first started driving, I was completely baffled by the shiftlock and had no idea what it was for. Later, I learned that it's a safety lock on automatic transmission vehicles, mainly located on the gear lever. You have to press the brake pedal to push the button or release the lock before you can shift from park to other gears. Its purpose is to prevent accidental gear shifts that could cause the car to move suddenly—like mistakenly shifting into reverse at a red light, which could have dangerous consequences. I tried a few times forgetting to press the brake, and the gear lever just wouldn't budge, leaving me really flustered. Now, after driving for several years, I truly appreciate how important this feature is, especially in crowded city traffic. As a new driver, I suggest the first thing you do after buying a car is to understand this mechanism—don’t learn the hard way like I did. It’s electronically controlled and linked to both the brake system and transmission, so pressing the brake activates the unlock. If you have kids, make sure to remind them not to mess with it to avoid accidents. In short, the shiftlock is a safety guardian designed to protect you.

Should the Changan Eado use 92 or 95 octane gasoline?

Changan Eado can use 92 octane gasoline, and 95 octane gasoline is also acceptable. This gasoline grade is recommended in the official vehicle user manual for this car. In addition to checking the appropriate gasoline grade in the vehicle user manual, the Changan Eado also has it indicated on the fuel tank cap, which can be checked there as well. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, those between 10.0-11.5 should use 95 octane gasoline, and if the compression ratio is higher, 98 octane gasoline is recommended. However, with the application of some new technologies, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be tuned to use lower octane gasoline because, apart from 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 number, the higher the octane value 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 Changan Eado occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, and the actual feedback will be poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane value is too low, the gasoline's ignition point decreases and it may ignite prematurely during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance will make the engine run very unstably. If it's mild knocking, it only increases noise and does not significantly damage the engine. However, if there is noticeable knocking, it indicates severe engine conditions. The vibration not only affects driving stability but can also cause abnormal wear on the pistons and cylinders, and in severe cases, even cylinder scoring.

What are the test items for the automatic transmission vehicle in Subject 2?

The C2 Subject 2 test consists of 4 items: reverse parking, parallel parking, curve driving, and right-angle turning. Compared to the C1 manual transmission test, it excludes the hill start item. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), starting from June 1, 2021, the C2 and C5 Subject 2 tests no longer assess hill parking and starting. Reverse parking is one of the more challenging items in the Subject 2 test, so many test centers have designated it as the first test item. The key points for reverse parking are: the full-lock steering wheel point, the 30 cm correction point, and the parking point inside the bay. You must follow the specified route and sequence. The vehicle must be parked inside the bay without crossing the lines. Parallel parking focuses on aligning the front line of the parking space with the rear wheels, spotting the rear corner in the rearview mirror, and maintaining the distance between the wheels and the left dashed line. After parking, the wheels do not need to be straightened, and don’t forget to use the turn signal when exiting. The vehicle body must not cross the lines after parking, and the tires must not touch the lane boundary lines during movement. Curve driving, commonly known as the S-curve, is relatively easy for many students with good driving sense, who can complete it intuitively. However, some students misjudge the line positions during the actual test, leading to immediate failure by crossing the lines. The key to the S-curve is observing the reference points on the front hood and the position of the boundary lines. The wheels must not press the road edge lines. Right-angle turning is even simpler, essentially a simplified version of the exit part in reverse parking. The method for finding the reference point is the same as exiting the bay, based on the relationship between the horizontal line of the front hood and the front line (just touching or slightly delayed). Ensure the wheels do not press the road edge lines. Generally, the required training hours for C1 Subject 2 are 16 hours, while for C2 Subject 2, it’s 14 hours. Completing the required hours is a basic requirement for taking the Subject 2 test. Training hours can only be increased, not reduced, and additional test items require corresponding extra hours. Each training hour is 60 minutes, with effective teaching time not less than 45 minutes. If you fail Subject 2, you can retake it once. If you fail the retest, the current test session ends, and you must reschedule the test after 10 days. If you fail five consecutive test attempts (including retests, totaling 10 attempts), all previously passed subject scores will be invalidated, and you must restart from Subject 1.

How to Deal with Black Paint Scratches on a White Car?

When black paint gets scratched onto a white car, the specific situation and solutions are as follows: 1. Dirt adhesion: If the black marks are merely dirt adhering to the paint surface, simply washing and wiping them off will suffice. 2. Exposed primer: If the scratch has removed the surface paint of the car, in minor cases, you can use a touch-up pen to repair it yourself. For more severe cases, sandpaper can be used to sand off the paint at the scratched area, followed by repainting. 3. Deformation: If the impact is particularly severe and causes deformation of vehicle parts, it is necessary to visit a 4S shop or repair shop for professional repair by specialists.
