1. OVERVIEW
By using the planetary gear sets, two-gears shift type part time transfer case achieves direct
connection when selecting 4WD "HIGH" and 2.48 of reduction gear ratio when selecting 4WD
"LOW". The silent chain in transfer case transfers the output power to front wheels.
The simple operation of switches on instrument panel allows to shift between "2H" and "4H" easily
while driving (for 4L: stop vehicle first). The warning lamp warns the driver when the system is
defective.

Operation ▶
Description Mode Conditions
Driving mode 2H 2 Wheel drive
(rear wheel)Rear-wheel drive mode. This is used under
normal or high-speed driving conditions on public
roads or highways.
4H 4 Wheel drive
(high speed)This is used under sandy, muddy or snow-
covered road conditions
4L 4 Wheel drive
(low speed)This is used for maximum traction.
When cornering with low speed in 4WD condition,
there could be tire dragging, some
mechanical shocks and resistances in vehicle’s
drive train. These are normal conditions due to
internal resistance in the drive train when the
4WD system is properly working

To make the mode change easily, stop the
vehicle on level ground and turn the mode
switch to the desired position and move the
shift lever to "N"-"R"-"N" while depressing
the brake pedal. For Automatic Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Turn the switch to the desired position. -
For Manual Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Then turn the switch to the desired position
while depressing the clutch pedal. -

4. IWE LOCKING HUB SYSTEM
1) Overview
The vacuum locking hub uses the IWE (Integrated Wheel End) system, and in this system, the
vacuum is generated only within the hub actuator.
It is structured to transmit power to the front section after the actuator hub is engaged following
the release of vacuum from the drive shaft end gear and the hub end gear
