timing a time period between sensing application of the operator's arm to the armrest and removal of the operator's arm from the armrest;
comparing the time period to a delay interval;
enabling control responsive to sensing application of the operator's arm to the armrest, when the time period is more than the delay interval; and
disabling control responsive to sensing removal of the operator's arm from the armrest when the time period is more than the delay interval.
