Vibration of the throttle pedal during high-speed driving is caused by looseness in the ball joint of the steering tie rod. Below are specific details about the throttle pedal: 1. Starting: The operation of the throttle pedal should use the right heel placed on the floor of the driver's compartment as a pivot point, with the sole gently pressing on the accelerator pedal, using the flexion and extension of the ankle joint to press down or release. When pressing or releasing the throttle pedal, the force should be gentle, ensuring a light press and slow release. 2. Starting the engine: Do not press the throttle pedal all the way down; it is better to have it slightly above the idle throttle. When starting, it is advisable to apply a bit of throttle just before the clutch engagement point, with the throttle opening ideally set to a small or medium level. 3. During operation: The throttle should be increased or decreased according to road conditions and actual needs. Select an appropriate gear to ensure the engine operates mostly at medium speed and with a larger throttle opening to save fuel.

What is the minimum ground clearance of the New Vision?

The minimum ground clearance of the Geely Vision under full load is 120MM. The Vision X1 adopts Geely's latest generation of family design language, presenting a visually dynamic appearance. The ripple-patterned grille offers high brand recognition, and the integration of the headlights with the grille aligns with current design trends. The new car features black plastic cladding around the body, catering to its SUV positioning. More details are as follows: 1. The greater the minimum ground clearance, the stronger the vehicle's ability to pass over obstacles or uneven terrain, but the higher center of gravity reduces stability. Conversely, the smaller the minimum ground clearance, the weaker the vehicle's ability to navigate obstacles or rough surfaces, but the lower center of gravity enhances stability. 2. The minimum ground clearance must consider the passability of loading and unloading platforms during transportation, as well as the likelihood of avoiding scraping when the car approaches ordinary sidewalk edges. If the vehicle is destined for sale in a specific country or region, local road conditions must also be taken into account.
