What are the 'Three Touches and One Belt' in Subject Three?

[Juliet]

The 'Three Touches and One Belt' in Subject Three refers to the preparatory actions before starting the vehicle, with variations in different regions. It involves touching the sensors on the rearview mirror, the left side mirror, and under the seat, adjusting the seat to a comfortable position, fastening the seatbelt, igniting the engine, turning on the low beam headlights, and beginning the nighttime simulated lighting test. Confirming Surrounding Safety: In some areas, pressing the sensors is not required, but walking around the vehicle remains essential. First, ensure the surrounding environment is safe. Even the most advanced radar and reversing camera systems have blind spots, making personal observation crucial. Due to the vehicle's large size, sitting inside does not provide a full view of the entire vehicle. Checking Tire Condition: Tire condition directly impacts driving safety. Bulges or insufficient tire pressure during use can easily lead to blowouts, which may cause serious accidents. Walking around the vehicle also helps detect any foreign objects like nails that could puncture the tires. Early Detection of Vehicle Scratches: When parked on public roads or in parking lots, vehicles are vulnerable to unexpected damage.
