Variant Coding Options
(2) Detects the position of the shifting lever for the HDC operation
among ABS functions.
The HDC function operates only if the M/T shift lever is in forward or reverse position. Please refer
to the ABS section for the specific information related to the HDC.
Variant Coding Related to N Switch ▶
The N switch transmits information to the ECU through the CAN communication while New Rexton
is connected to the ECU through wires. Thus, if you set the variant coding in the engine ECU, you
must do it differently, and you must set the variant coding differently according to the vehicle
category and specification as below.

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
The propeller shaft transfers the power through the transmission and transfer case to the front/rear
axle differential carrier (final reduction gear).
It is manufactured by a thin rounded steel pipe to have the strong resisting force against the torsion
and bending.
Both ends of propeller shaft are connected to the spider and the center of propeller shaft is
connected to the spline to accommodate the changes of the height and length.
The rubber bushing that covers the intermediate bearing keeps the balance of rear propeller shaft
and absorbs its vibration.
Function of propeller shaft ▶
Transmits driving torque.
Compensates the angle change (universal joint / CV joint).
Compensates the axial length change (splines for the slip joint). -

Operation ▶
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

(low speed)For Automatic Transmission:
For Manual Transmission:
Stop the vehicle on level ground and
move the gear selector lever into the
“N” position. Turn the switch to the
desired position. ·
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. ·
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.
