The locking rear axle can give the vehicle additional traction from the rear wheels when traveling in off-road situations such as mud, snow, sand, steep hills and uneven terrain.
The button used to turn this feature on or off is located below the transfer case dial to the right of the steering wheel.
To lock the rear axle:
- Place the transfer case in the Four-Wheel-Low Lock mode. This is the only mode which will allow the rear axle to lock. See Full-Time Four-Wheel Drive for more information regarding the transfer case and Four-Wheel-Low-Lock mode.
- Press the button with the vehicle stopped or moving less than 2 mph (3 km/h).
The light in the button must stop flashing and remain illuminated before the rear axle is locked.
Notice: If you try to lock the axle while the vehicle is stuck and the tires are spinning, the vehicle's drivetrain could be damaged. The repairs would not be covered by the vehicle warranty. Always lock the axle before attempting situations and/or navigating terrain which could possibly cause the vehicle to become stuck.
The locking rear axle will be disengaged when the vehicle's speed is greater than 40 mph (64 km/h), if the vehicle's battery is low and/or the transfer case is shifted out of Four-Wheel-Low-Lock mode.
Notice: If the vehicle's axle is locked while driving on pavement, the drivetrain could be damaged. Repairs would not be covered by the vehicle warranty. Do not use the locking axle on pavement. If four-wheel drive is needed when traveling on pavement, use only 4HI.
