322 STARTING AND OPERATING Transfer Case Position Indicator Lights - Electronically Shifted Transfer Case Only Transfer case position indicator lights are located in the instrument cluster and indicate the current and desired transfer case selection. When you select a different transfer case position, the indicator lights will do the following: If All Shift Conditions are Met 1. The current position indicator light will turn OFF. 2. The selected position indicator light will flash until the transfer case completes the shift. 3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON. If One or More Shift Conditions are not Met 1. The indicator light for the current position will remain ON. 2. The newly selected position indicator light will continue to flash. 3. The transfer case will not shift. NOTE: Before retrying a selection, make certain that all the necessary requirements for selecting a new transfer case position have been met. To retry the selection, turn the control knob back to the current position, wait five (5) seconds, and retry selection. To find the shift requirements, refer to the Shifting Procedure for your transfer case, located in this section of the owner's manual. The "SERVICE 4WD" warning light monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required.
