Dodge 2010 Nitro - Manual (Page 310)

The electronically shifted transfer case is designed to be
driven in the two-wheel drive position (2WD) for normal
street and highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4WD LOCK position can be used to lock the front and
rear driveshafts together and force the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the transfer case switch to the desired posi-
tion. Refer to “Shifting Procedure” for specific shifting
instructions. The 4WD LOCK position is designed for
loose, slippery road surfaces only.
CAUTION!
• Driving in the 4WD LOCK position on dry hard
surfaced roads may cause increased tire wear and
damage to the driveline components.

CAUTION! (Continued)
• Do not attempt to make a shift while only the front
or rear wheels are spinning. Shifting while only
the front or rear wheels are spinning can cause
damage to the transfer case.
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
transfer case. Tire rotation schedule should be followed
to balance tire wear.
Since 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.
