Should the Protective Film on the Car Dashboard Be Removed?
2 Answers
It is recommended to remove the protective film on the dashboard of a new car, as prolonged adhesion can leave marks. Below is relevant information about the car dashboard: 1. Speedometer and Odometer: The speedometer and odometer are actually composed of two gauges. One is the speedometer, and the other is the odometer. Traditional speedometers are mechanical. A typical mechanical odometer is connected via a flexible shaft, which contains a steel cable. The other end of the flexible shaft connects to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn rotates a magnet inside the odometer housing. 2. Tachometer: The tachometer is usually located on the instrument panel, placed symmetrically with the speedometer and odometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. These signals are then converted into a readable RPM value. The faster the engine speed, the more pulses the ignition coil generates, resulting in a higher RPM reading on the gauge.
I had the same question when buying my car. That film on the dashboard is meant to protect the surface from scratches during transportation, but it's not a permanent design. It's recommended to remove it once you take delivery of the new car. If left on, the film will gradually accumulate dust or bubbles, making instrument readings appear blurry—especially with sunlight glare, which can distract you while checking speed or fuel levels. Worse yet, over time the film may degrade and stick to the screen, making cleanup a hassle that requires careful wiping with alcohol or a soft cloth. After using my new car for a week or two, I peeled it off—the process was simple, just gently lift from one corner without using sharp tools to avoid scratches. Keeping the dashboard clean during daily driving is more important; regular wiping with a damp cloth prevents dust buildup. In short, for safety and clarity, removing it early saves a lot of trouble.
