This is an electronically shifted transfer case and is operated by the 4WD Control Switch (Transfer Case Switch), which is located on the instrument panel.
Four-Position Transfer Case
This electronically shifted transfer case provides four positions:
-
Two-Wheel Drive High Range (2WD)
-
Four-Wheel Drive High Range (4WD HIGH)
-
Four-Wheel Drive Low Range (4WD LOW)
-
N (Neutral)
For additional information on the appropriate use of each transfer case position, see the following information:
2WD
Two-Wheel Drive High Range — This range is for normal street and highway driving on dry, hard surfaced roads.
4WD HIGH
Four-Wheel Drive High Range — This range provides torque to the front driveshaft (engages four-wheel drive) which allows front and rear wheels to spin at the same speed. This provides additional traction for loose, slippery road surfaces only.
4WD LOW
Four-Wheel Drive Low Range — This range provides low speed four-wheel drive. It maximizes torque (increased torque over 4WD HIGH) to the front wheels, allowing front and rear wheels to rotate at the same speed. This range provides additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h) in this range.
N (Neutral)
N (Neutral) — This range disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle Towing This Vehicle Behind Another Vehicle.
-
You or others could be injured or killed if you leave the vehicle unattended with the transfer case in the N (Neutral) position without first fully engaging the parking brake. The transfer case N (Neutral) position disengages both the front and rear drive shaft from the powertrain, and will allow the vehicle to roll, even if the transmission is in PARK. The parking brake should always be applied when the driver is not in the vehicle.
-
The transmission may not engage PARK if the vehicle is moving. Always bring the vehicle to a complete stop before shifting to PARK, and verify that the transmission gear position indicator solidly indicates PARK (P) without blinking. Ensure that the vehicle is completely stopped, and the PARK position is properly indicated, before exiting the vehicle.
This electronically shifted transfer case is designed to be driven in the two-wheel drive position (2WD) for normal street and highway conditions on dry, hard surfaced roads. Driving the vehicle in two-wheel drive will have greater fuel economy benefits as the front axle is not engaged in two-wheel drive.
When additional traction is required, the transfer case 4WD HIGH and 4WD LOW positions can be used to maximize torque to the front driveshaft, forcing the front and rear wheels to rotate at the same speed. This is accomplished by pushing the desired position on the four-wheel drive control switch.
For specific shifting instructions Shifting Procedure.
The 4WD HIGH and 4WD LOW positions are designed for loose, slippery road surfaces only. Driving in the 4WD HIGH and 4WD LOW positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components.
The transfer case NEUTRAL button is located in the center of the four-wheel drive Control Switch and is pushed by using a ballpoint pen or similar object. The transfer case NEUTRAL position is to be used for recreational towing only Towing This Vehicle Behind Another Vehicle.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and 4WD LOW) 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:
-
The current position 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 indicator light for the selected position will stop flashing and remain on.
If One Or More Of The Following Shift Conditions Are Not Met:
-
The indicator light for the current position will remain on.
-
The newly selected position indicator light will continue to flash.
-
The transfer case will not shift.
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, push the current position, wait five seconds, and retry selection. To find the shift requirements Shifting Procedure.
The SERV 4WD Warning Light monitors the electronic shift 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.
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 or death.
Do not attempt to make a shift while only the front or rear wheels are spinning. This could 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 given road speed. Take care not to overspeed the engine and do not exceed 25 mph (40 km/h).
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.
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.
