The vehicle SN number usually refers to the Vehicle Identification Number, commonly known as the VIN. It's essentially a unique 17-character alphanumeric code that serves as an identifier for each vehicle, much like an ID card. I first realized its importance when buying my first car, as the dealership used it to check the vehicle's history. Typically, it's located on a small plate in the corner of the windshield or on the door pillar. I also discovered that it contains a lot of information, such as the manufacturing year, production location, and model details. When getting repairs, mechanics use it to match parts, which is super convenient. I also make a habit of noting it down, just in case the car gets stolen, so the police can track it quickly. Overall, it's a key element in ensuring a vehicle's safety and reliability, and new car owners should familiarize themselves with it early on.

What does 'Please repair the traction control system' mean?

When braking on slippery roads, the wheels may skid, even causing loss of control of the direction.

What Causes the Hissing Friction Sound When Turning the Steering Wheel?

The reasons for the hissing friction sound when turning the steering wheel: 1. If the turn signal is activated while turning, this sound may be caused by the rebound clip of the automatic turn signal return mechanism; 2. If the abnormal noise comes from below the steering wheel, it might be due to the dust cover of the steering column. Lack of lubrication in the steering column dust cover can cause friction sounds; 3. If the noise originates from outside the vehicle, it could be due to insufficient lubrication in the shock absorber's plane bearing. If the plane bearing of the shock absorber is making noise, applying some grease to it may help. If the noise persists after greasing, replacement may be necessary.
