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

■ Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering

Should this occur, refrain from excessive
steering input or stop the vehicle and turn
the engine off. The EPS system should
