DCDL Operation
Warning: Locking the wheels when the vehicle is traveling down steep grades or when the wheels are slipping could damage the differential and/or lead to loss of vehicle control, causing personal injury and property damage.
Notice: Engage the driver-controlled differential lock (DCDL) only when the vehicle is stopped or moving at less than 5 mph (8 km/h). Engaging the DCDL at speeds above 5 mph (8 km/h) can cause internal axle damage.
Important: If equipped with the optional automatic disengagement feature, the DCDL will not engage at speeds above 5 mph (8 km/h) and automatically disengages at 25 mph (40 km/ h). The parameters of this feature are not modifiable.
Note: If the DCDL is engaged when the vehicle is shut down, the DCDL disengages.
- With the key ON, press the upper half of the differential lock dash switch or the differential lock bubble on the Axles screen to engage the DCDL.
- If the vehicle is moving, briefly let up on the accelerator
to relieve torque on the gears, allowing the differential to fully
lock.The indicator light on the differential lock switch illuminates solid amber and the bubble on the infotainment display illuminates solid yellow when the lock is engaged.
- Drive cautiously and do not exceed 25 mph (40 km/h). When
the differential is fully locked, the turning radius increases because
the vehicle under steers. See Fig. .
-
The turning radius increases when the DCDL is engaged (understeer condition).
-
The turning radius decreases when the DCDL is disengaged.

- To disengage the DCDL after leaving poor road conditions,
briefly let up on the accelerator to relieve torque on the gears and
press the lower half of the differential lock dash switch or select
the yellow bubble on the Axles screen in the infotainment display.When the lock disengages, the indicator light on the switch deactivates and the lock bubble on the Axles screen illuminates blue.
- Resume driving at normal speed.
Warning: Be especially careful when driving under slippery conditions with the differential locked. Though forward traction is improved, the vehicle can still slip sideways, causing possible loss of vehicle control, personal injury, and property damage.
