SERVICE INFORMATION
As of January 1989 production, a shift interlock is installed which will prevent the selector lever from being moved out of position "P" without depressing the brake pedal first.
During the pre-delivery inspection, the shift interlock must be checked for proper functioning and any adjustments necessary must be performed at this time.
