EPS operation sound

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

heard. This does not indicate a malfunction.

■

Reduced effectiveness of the EPS system

The effectiveness of the EPS system is reduced to prevent the system from over-

heating 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 EPS system should

return to normal within 10 minutes.
