Electronically Shifted Transfer Case Operating
Information/Precautions (4 Position Switch) — If
Equipped
This is an electric shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel.
This Electronically Shifted transfer case provides 4 mode
positions: 2 (rear) wheel drive high range, 4 wheel drive
lock range, 4 wheel drive low range, and neutral.
The Electronically Shifted transfer case is designed to be
driven in the 2 wheel drive position (2WD) for normal
street and highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4WD LOCK and 4WD LOW positions 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 4WD Control Switch to the
desired position - see Shifting Procedure section for
specific shifting instructions. The 4WD LOCK and 4WD
LOW positions are designed for loose, slippery road
surfaces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
