Electronic Shift On the Fly (ESOF) 4x4 system (if equipped)
If equipped with the electronic shift 4WD System, and the
instrument panel control is moved to 4X4 LOW (4WD Low) while
the vehicle is moving above 3 mph (5 km/h), the system will not
engage and no damage will occur to the 4WD system. Before 4X4
LOW (4WD Low) can be engaged, the vehicle speed must be
below 3 mph (5 km/h) with the brake pedal depressed and the
transmission in N (Neutral). This vehicle is equipped with a
non-synchronous low range gearset which will not allow the
transfer case to shift into 4X4 LOW (4WD Low) if vehicle speed
is above 3 mph (5 km/h). It is recommended that a shift to 4X4
LOW (4WD Low) is performed while the vehicle is moving at a
speed below 3 mph (5 km/h).
The 4WD system:
•
provides 4x4 High engagement and disengagement while the vehicle is
moving.
•
is operated by a rotary control located on the instrument panel that
allows you select 2WD, 4x4 High or 4x4 Low operation.
•
uses auto-manual hub locks that can be engaged and disengaged
automatically based on the 4x4 mode selected.
•
auto-manual hub locks can be
manually overridden by rotating
the hub lock control from AUTO
to LOCK if desired.
•
automatic operation of the
hub locks is recommended,
and
will increase fuel economy
•
For proper operation, make
sure that each hub is fully
engaged and that both hub
locks are set to the same position (both set to LOCK or both
set to AUTO). To engage LOCK, turn the hub locks completely
clockwise; to engage AUTO, turn the hub locks completely
counterclockwise.
