The reasons for the airbag light being on in a sedan are: 1. Foreign objects around the airbag sensor wiring harness causing false alarms of the warning light; 2. Error in the car ECU sensor data; 3. The vehicle has been parked in a humid environment for a long time or the wiring interface became damp during car washing; 4. Fault in the airbag itself; 5. Loose connectors. The airbag is an auxiliary protective device made of special fabric nylon with a rubber lining and filled with harmless helium gas when activated. The solutions for the airbag light being on in a sedan are: 1. Check the connection of the connectors; 2. Check the contact condition of the grounding wire; 3. Take the vehicle to a 4S shop for computer diagnosis and troubleshooting; 4. Use an inspection tool to check the airbag system and read the fault codes.

Should I Use Turn Signals When Parallel Parking in Reverse?

Do not use turn signals when parallel parking in reverse. Parallel parking tips: Maintain a 30 cm distance: Approach the car in front, keeping a distance of about 30 cm. Too far and you may not fit in, too close and you risk scratching the other car. Stop when your car's side mirrors align with those of the adjacent vehicle. If parking next to a large SUV, you may need to adjust your position slightly further back. Observe the left rearview mirror: Straighten the steering wheel when your car's edge aligns with the right edge of the car behind you. Then continue reversing straight back, making minor adjustments to your car's position as needed.
