The 15-digit certificate number is located on the vehicle certificate that comes with the car when it leaves the factory. When picking up the car, the owner can request the vehicle certificate from the 4S store staff and check the certificate number on it. However, the vehicle certificate needs to be submitted to the DMV for retention when the owner registers the new car for a license plate. More relevant information is as follows: Note 1: If the owner wants to check the vehicle certificate number after submitting it, they can consult the car dealer to see if the DMV where the vehicle is registered can provide the certificate number based on the engine number. Additionally, by comparing the engine number, they can verify whether the factory records of the car match the engine number on the vehicle registration certificate. Note 2: Besides the vehicle certificate, the 4S store should also provide the owner with other documents such as the car purchase invoice, vehicle user manual, and warranty service card. Otherwise, it may negatively impact the owner's license plate registration and maintenance after picking up the car, causing unnecessary trouble.

When I first bought my new car, I paid special attention to this 15-digit certification number. The salesperson told me it was on a small white label at the lower left corner of the windshield, a combination of numbers and letters that was easy to spot when inspecting the car. I also received a certification document folder containing the printed original, and the dealer emphasized this information during the handover. Later, I learned that this number is used for license registration, insurance, and annual inspections—it's indispensable in critical moments. If the label is worn and illegible, simply take a photo of the license plate or scan the QR code; some car apps can help retrieve the record. Keeping the documents safe is crucial—I once misplaced the folder during a move, but luckily the label was still on the car to resolve the issue. The placement is designed to be obvious, making checks effortless. The car-buying process was smooth overall, and the salesperson was very responsible in explaining all the details, making it easy even for a beginner to handle.

As an experienced driver with years behind the wheel, I've checked this certification number countless times. It's located on the label at the lower left corner of the windshield - a standard position that's immediately recognizable. The printed version also comes with the vehicle purchase documents, and I recommend new owners scan and save a backup on their phones. Once when I lost the document, the dealership helped me quickly reissue it since they had the information archived in their system. This number is crucial for license plate registration and insurance, so don't misplace it. The location is fixed and usually easy to find, but make sure the label isn't covered. A quick glance is all it takes - nothing complicated.

What is the HOLD light?

HOLD light is the gear lock indicator light. When the HOLD light is on, it indicates that the gear is locked in a specific position. When driving uphill or on icy/snowy roads that require low-gear operation, you can activate HOLD to lock the transmission in second gear. The button for this switch is located in the middle of the gear lever. Pressing it again will deactivate the function. Normally, it's not recommended to use this feature as it may harm the transmission. Automatic gear lock is a forced downshift key, used when gears get stuck or during towing. When HOLD is activated, the parking brake system will automatically engage each time the vehicle comes to a complete stop after braking. You'll feel a release of pressure on the brake pedal, at which point you can release the pedal without worrying about the vehicle rolling. Working principle of gear lock indicator light: The transmission control unit uses this sensor to detect the gear selected by the driver and performs corresponding control actions. Relationship between neutral switch and gear position switch: In older vehicles, the P (Park) and N (Neutral) switches were connected in series with the starter motor switch, meaning the engine could only be started in these two positions. In newer vehicles, the control unit identifies the neutral signal first, then decides whether to engage the starter motor.

What Causes Difficulty in Removing the Car Key?

Car key difficulty in removal can be attributed to the following reasons: 1. P gear not properly engaged: When exiting the vehicle, the gear was not shifted to P or the P gear did not fully engage, possibly obstructed by an object, thus failing to trigger the electronic sensor. 2. Steering wheel locked: The steering wheel was not returned to its proper position when parking, causing an abnormal lock. The solution is to insert the key, attempt to turn the steering wheel left and right while twisting the key, which will release the steering wheel lock. 3. Obstruction in the key slot: The solution involves removing the obstruction, starting the car, shifting the gear again to ensure it is fully engaged, after which the key can be removed.
