Is Heavy Steering Wheel in Winter Normal?

[VonMalia]

Heavy steering wheel in winter is not normal and may indicate issues with the power steering system or its lubricating oil, requiring immediate inspection and repair at a 4S shop. Low winter temperatures slow down air molecule movement, leading to a slight decrease in tire pressure and increased contact area between tires and the ground, which can make the steering wheel feel heavier. The function of the steering wheel is to convert the force applied by the driver on its rim into torque, which is then transmitted to the steering shaft. Precautions for using the steering wheel include: 1. Avoid excessive force when turning the steering wheel and refrain from making sudden turns or corrections; do not turn the steering wheel when the vehicle is stationary. 2. When driving on bumpy roads, hold the steering wheel firmly with both hands to prevent loss of control and potential accidents. 3. Reduce speed when turning. 4. Gradually turn the steering wheel according to the curvature of the bend when entering a curve.
