EPS system operation sound
When the steering wheel is operated, a motor sound (whirring sound) may

Reduced effectiveness of EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of

refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal within 10 minutes.
