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.
Clutch master cylinder (mounted on clutch pedal)
Concentric slave cylinder pipe (mounted inside of transmission) -
-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.

3. REAR AXLE
The rear axle installed in this car is a removable axle, called IRDA (Independent Rear Differential Axle).
The rear differential carrier is installed directly on the sub frame,
and there is an independent suspension that allows each wheel on the same axle to move vertically and
independently of each other with the universal joint and the slip joint.

1. OVERVIEW
The AWD system in this vehicle is the electronic 4WD system and controls the traction to rear wheels
according to the driving conditions.
1) Driving Mode
(1) AUTO mode (Normal driving mode)
Normally the vehicle is in 2WD mode.
Automatically change to this mode when the vehicle needs higher traction.
(2) LOCK mode (when pressing 4WD LOCK switch)
This mode provides the highest traction. Use
this mode when driving on unpaved, rugged,
steep, sandy, wet or slippery roads.
In 4WD LOCK mode, if the rear wheel speed
exceeds 40 km/h, 4WD LOCK mode is
canceled and 4WD AUTO mode is activated
(Indicator OFF). If the speed is decreased
below 35 km/h, 4WD LOCK mode is resumed
(Indicator ON again). -

and transfer it to E-coupling to distribute the torque to rear wheels.
(2) E-Coupling (Electronic Coupling)
E-Coupling transfer the engine torque from PTU to rear axle and controls to distribute it between front
wheels and rear wheels.
(3) E-Coupling Control Unit (ECU)
E-Coupling controls the current (clutch engagement force) of EMCD in E-Coupling according to CAN
signals (wheel speed, engine torque, pedal position, ABS/ESP signals).

1. OVERVIEW
Even though a driver cuts off the power, while driving, the vehicle continues to move due to the law of
inertia. Therefore, a braking device is needed to stop the vehicle. The brake system normally uses the
frictional discs that converts the kinetic energy to the thermal energy by frictional operation. The brake
system consists of the brake disc (front wheel), brake disc or drum (rear wheel), parking brake
(mechanical type), master cylinder, booster, pedal and supply lines (pipes and hoses).
Hydraulic brake ▶
Brake pedal ▶This system uses the leverage effect and Pascal's
principle. When depressing the brake pedal, the
pedal pressure is increased by booster and is
delivered to master cylinder to generate hydraulic
pressure. The hydraulic pressure generated by
the master cylinder is delivered to the brake
caliper through the brake pipes or hoses. This
hydraulic pressure pushes the brake calipers,
accordingly the caliper pads are contacted to
brake disc to generate the braking force.
Brake pedal uses the leverage effect to apply
bigger force to the brake master cylinder.
