STARTING AND OPERATING 225
alignment and shift completion to occur. The
preferred method is with the vehicle rolling at 2 to
3 mph (3 to 5 km/h). Avoid attempting to engage
or disengage 4L with the vehicle moving faster
than 2 to 3 mph (3 to 5 km/h).
Trac-Lok Rear Axle — If Equipped
The Trac-Lok rear axle provides a constant
driving force to both rear wheels and reduces
wheel spin caused by the loss of traction at one
driving wheel. If traction differs between the two
rear wheels, the differential automatically
proportions the usable torque by providing
more torque to the wheel that has traction.
Trac-Lok is especially helpful during slippery
driving conditions. With both rear wheels on a
slippery surface, a slight application of the
accelerator will supply maximum traction.
Axle Lock (Tru-Lok) — Rubicon Models
The axle lock switch is located on the instru-
ment panel (to the right of the steering column).
Axle Lock Switch Panel
This feature will only activate when the following
conditions are met:
Ignition in RUN position, vehicle in 4L (Low)
range.
Vehicle speed should be 10 mph (16 km/h)
or less.
Both right and left wheels on axle are at the
same speed.
To activate the system, push the axle lock
switch down to lock the rear axle only (the
“REAR ONLY” will illuminate), push the switch
up to lock the front axle and rear axle (the
“FRONT + REAR” will illuminate). When the rear
axle is locked, pushing the bottom of switch
again will lock or unlock the front axle.
NOTE:
The indicator lights will flash until the axles are
fully locked or unlocked.
To unlock the axles, push the axle lock OFF
button.
Axle lock will disengage if the vehicle is taken
out of 4L (Low) range, or the ignition switch is
turned to the OFF position.
The axle lock disengages at speeds above
30 mph (48 km/h), and will automatically
re-lock once vehicle speed is less than 10 mph
(16 km/h).
WARNING!
Failure to engage a transfer case position
completely can cause transfer case damage
or loss of power and vehicle control. You
could have a collision. Do not drive the
vehicle unless the transfer case is fully
engaged.
WARNING!
On vehicles equipped with a limited-slip
differential, never run the engine with one
rear wheel off the ground. The vehicle may
drive through the rear wheel remaining on the
ground and cause you to lose control of your
vehicle.
