STARTING AND OPERATING 135 3. The transfer case will not shift. given road speed. Take care not to overspeed the engine and do not exceed 25mph (40km/h). the selected position will stop flashing and remain ON. 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 switch back to the current position, wait five seconds, and retry selection Ъ page135. The SERV 4WD Warning Light monitors the electronically shifted four-wheel drive system.
If this light remains on after engine start-up or illuminates during driving, it means that the four-wheel drive system is not functioning properly and that service is required. Proper operation of four-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the drivetrain. 2WD TO 4WD HIGH Push the desired position on the four-wheel drive control switch to shift the transfer case. Shifts between two-wheel drive and 4WD HIGH can be done with the vehicle stopped or in motion.
With the vehicle in motion, the transfer case will engage/disengage faster if you momentarily release the accelerator pedal after turning the control switch. If the vehicle is stopped, the ignition switch must be in the ON/RUN position with the engine either running or off. This shift cannot be completed if the ignition switch is in the ACC position. Because four-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit. Shifting Procedure 4 NOTE: If any of the requirements to select a new transfer case position have not been met, the transfer case will not shift.
The position indi cator light for the previous position will remain ON and the newly selected position indicator light will continue to flash until all the require ments for the selected position have been met. To retry a shift: return the control switch back to the original position, make certain all shift requirements have been met, wait five seconds and try the shift again. WARNING! NOTE: The four-wheel drive system will not allow shifts between 2WD/4WD HIGH if the front and/or rear wheels are spinning (no traction). In this situation, the selected position indicator light will flash and the original position indicator light will remain on.
At this time, reduce speed and stop spinning the wheels to complete the shift. Always engage the parking brake when powering down the vehicle if the SERV 4WD Warning Light is illuminated. Not engaging the parking brake may allow the vehicle to roll, which may cause personal injury. NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning, as this can cause damage to driveline components.
When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the two-wheel drive or 4WD HIGH positions at a If all the requirements to select a new transfer case position have been met, the current posi tion indicator light will turn OFF, the selected position indicator light will flash until the transfer case completes the shift. When the shift is complete, the position indicator light for 2WD OR 4WD HIGH TO 4WD LOW NOTE: When shifting into or out of 4WD LOW some gear noise may be heard. This noise is normal and is not detrimental to the vehicle or occupants.
