If the seat belt is not fastened, the airbag will still deploy. In the event of an accident where the deployment conditions are met, the airbag will inflate in stages or with reduced force. The function of the seat belt is: during a vehicle collision or when emergency braking is applied, the pretensioner will instantly retract, tightening the slack in the belt to securely restrain the occupant in the seat and prevent secondary collisions. The airbag consists of an inflation sensor and inflation system, and its purpose is to: protect occupants by reducing contact with interior objects, more evenly distributing head and chest impact forces, and absorbing the occupant's kinetic energy, thereby complementing the effectiveness of the seat belt.

Which gear should an automatic car be in when waiting at a red light?

When waiting at a traffic light in an automatic car, if the expected wait time is within 20 seconds, you can use D gear along with the foot brake. For situations with traffic congestion where the wait exceeds 30 seconds, shift to N gear and engage the handbrake. Below is relevant information about the N gear in cars: Main purpose: In automatic transmission models, engaging N gear creates a power interruption effect similar to shifting to neutral in manual transmissions, though there are some differences. Precautions: Automatic cars should not coast in neutral under non-special circumstances, as it is not only unsafe but can also lead to transmission failure due to insufficient lubrication of gears and other components caused by inadequate oil supply from the transmission oil pump.

How to Add Windshield Washer Fluid to a Car?

Steps to Add Windshield Washer Fluid to a Car: Park the Car: First, engage the handbrake to prevent the car from moving while adding windshield washer fluid. Open the Hood: Pull the front hood release lever located near the driver's side footwell to ensure the hood can be opened. Lift the hood and locate the windshield washer fluid reservoir. Open the Reservoir and Add Fluid: Open the cap of the windshield washer fluid reservoir. Pour in an appropriate amount of fluid, observing the fill line to avoid overfilling. Stop when the fluid reaches the marked line. Precautions: Avoid overfilling the reservoir. If you notice some foam around the opening, there’s no need to worry—it won’t affect the fluid’s performance. If the car is used in northern regions during winter, be sure to use antifreeze-type windshield washer fluid. For southern regions, a standard fluid with bug remover additives is usually sufficient.
