■Power Steering Malfunction Indicator Light
●If the indicator light illuminates/flashes, the power steering will not operate
normally. If this happens, the steering wheel can still be operated, however,
the operation may feel heavy compared to normal, or the steering wheel
could vibrate when turning.
● Repeatedly jerking the steering wheel left and right while the vehicle is
stopped or moving extremely slowly will cause the power steerin g system to
go into protective mode which will make the steering feel heavy , but this
does not indicate a problem. If this occurs, park the vehicle safely and wait
several minutes for the system to return to normal.
