2) Function of N Switch
(1) Aids a smooth start of the vehicle by raising the RPM during the gear
shifting when the engine is cold.
When the vehicle is trying to start from the stopped state (vehicle speed below 3 km/h), the N
switch determines the shifting timing by using the clutch switch and the N switch. It raises the
engine RPM (100 ~ 200 rpm). Operation conditions are as follows.
The vehicle speed is at the stopped state (Vehicle speed below 3km/h detection).
While depressing the clutch (Clutch switch detection).
The gear lever is at a position other than neutral (N switch detection).
Start the vehicle while depressing the clutch pedal (Clutch switch detection).
The RPM increases in accordance with the temperature of the engine coolant
(Engine coolant temperature sensor detection). -

When the gear has been smoothly shifted and the vehicle speed exceeds 3km/h, it returns to
the previous operation interval of the engine RPM. -
In case of Actyon, the N switch signal is transmitted to the instrument panel, and then the
instrument panel transmits it to the engine ECU through the CAN communication.

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. SATIC (SELF ADJUSTING TECHNOLOGY WITH
INTEGRATED CASSETTE)
1) System Description
Function ▶
On the conventional clutch, the pedal force
tends to increase in proportion to the degree
of disc run-out. However, the SATIC clutch
has the adjusting function which activates the
cassette system inserted to the clutch cover
to maintain a constant pedal force and
clearance when the disc runs out. (Unlike SAT
type, SATIC type does not need SST for
clutch cover removal.)
Operation ▶
Diaphragm spring rotates the adjusting
equipment as clutch disc is wearing and so,
pressure plate is pushed to clutch disc side at
the amount of wear.
Disc wear (Free
play) → Diaphragm spring (1)
→ Adjusting equipment (2, 3) → Pressure
plate (4)

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.

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
