EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
■
Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the engine off. The sys-
tem should return to normal within 10 minutes.
