Winter Mode (W) ▶
Low Range Driving Mode ▶
Warm Up Mode ▶ When the Winter mode is selected, the second gear is engaged to start off the vehicle easily to
prevent wheel spin on slippery surfaces and WINTER mode indicator comes ON. The first gear is
not available in this mode.
When the vehicle is in 4L driving mode, the transmission uses a different shift mode to optimize
the low range driving. Similar to Winter mode, the first gear is not available.
This mode is normally used when the transmission oil temperature is below 20°C.

1. OVERVIEW
The hydraulic clutch transmits the force required to operate the clutch pedal to the concentric
slave cylinder fitted to the clutch housing as a hydraulic pressure.
(The hydraulic pressure is transmitted in the following order: Clutch pedal - Clutch master
cylinder - Clutch pipe - Clutch damper - Clutch pipe and hose - Concentric slave cylinder -
Pressure plate - Flywheel.)
If a driver depress the clutch pedal, the hydraulic pressure is generated in the master cylinder. It
is transmitted to the concentric slave cylinder through the pipe, resulting in the cylinder being
forced out. At this time, the clutch disc is forced against the cylinder by pushing the cover. This,
in turn, remove the flywheel from the pressure plate. As a consequence, the power from the
engine will be cut off and the gear change can be carried out.

2) Overview
Driving elements ▶
The driving elements consist of two flat surfaces machined to a smooth finish.
One of these is the rear face of the engine flywheel and the other is the clutch pressure plate. The
clutch pressure plate is fitted into a clutch steel cover, which is bolted to the flywheel.
Driven elements ▶
The driven element is the clutch disc with a splined hub which is free to slide lengthwise along the
splines of the input shaft.
The driving and driven elements are held in contact by spring pressure. This pressure is exerted by
a diaphragm spring in the clutch cover pressure plate assembly.
Operating Elements ▶
The clutch "release" system consists of the clutch pedal and clutch release cylinder.
This system directly releases the clutch by using hydraulic pressure while the conventional clutch
system releases the clutch by using release lever and release fork. This system provides higher
efficiency than conventional clutch system, and its durability is superior.

3. DUAL MASS FLYWHEEL (DMF)
The dual mass flywheel (DMF) is of having a mass divided into two halves.
While one mass is connected to the engine crankshaft, which is affected by the mass moment of
inertia of the engine, the other mass is affected by one of the transmission.
The divided dual masses are connected to the coil spring and damping system internally.
The DMF has the following benefits: ▶
Reducing fuel consumption by lowering engine speed
Reducing rattling noise and vehicle vibration in all driving ranges
Reducing synchronization wear
Facilitating gear change
Protecting power train parts by preventing excessive load from being delivered -

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.

Description Mode Conditions
Driving
mode2H 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

move the shift lever to "N"-"R"-"N" while
depressing the brake 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
