1. WIPER CONTROL
2. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy
days, set the switch to the OFF position. Especially during the winter time, check if the wiper blades
are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield
can be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid
when the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers. -

Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to
work irregularly. Therefore, in this case, replace the wiper blade with a new one. -

- Irregular operation (abrupt operation) ▶ When cleaning the windshield over the sensor with damp clothes, the wiper may operate suddenly. It
could cause serious injury. Make sure to place the wiper switch to the OFF position and ignition switch
OFF when not in use.

IP display (SVC only)
When the gear selector lever is shifted into “R", the parking aid system is activated and three
sensors in the rear bumper detect the distance to any obstacle. The PAS detects the returning signals
reflected to the obstacles at regular intervals when the vehicle is parked to indicate the display and alarm
for the distance between the obstacles by phase so as to allow the driver easy parking by securing safe
distance.

Fuse for vehicle with EPS
The vehicle with EPS has EPS fuse (80A)
mounted to the positive (+) terminal of the
battery not in the fuse box.
EPS unit
The ECU controls the electric power
steering system depending on the driving
conditions, based on the signals from the
torque and angle sensor.
HECU (Hydraulic & Electronic Control Unit)
HECU for ABS HECU for EPS
The HECU (Hydraulic & Electronic Control Unit) determines the slip conditions of vehicle wheels by
calculating each wheel's speed and the increment/decrement of speed based on the information
detected by the sensors, and controls the pumping and boosting/reducing/keeping pressure by
operating the valve and motor of HECU.

Steering wheel angle sensor (SWAS)
The steering wheel angle sensor is mounted between
the steering column and the steering column shaft. It is
commonly used by the ESP (Electronic Stability
Program) system. And it receives signals of the steering
wheel angle sensor from the ESP HECU (Hydraulic &
Electronic Control Unit).

01-90000-00
G-sensor(4WD, ABS)
For the vehicle with the ABS, a speed difference
between the wheels is not noticeable as all the
wheels are slipping during abrupt braking.
Therefore, the vehicle needs the speed information
from other sensors other than the wheel speed
sensor. The longitudinal acceleration sensor (G-
sensor) is used for this case. It controls the ABS by
using the signals from the sensor during abrupt
braking and acceleration.
TCU unit
The transmission control unit (TCU) is installed under
the driver seat, and controls the transmission. The
TCU is operated by the ignition power supply and
receives and processes the following information from
the inner sensors through CAN buses.E-coupling unit
The E-coupling unit is a control unit which
determines the magnetic force by
considering CAN signals (wheel speed,
engine torque, pedal opening, ABS/ESP
CAN signals, etc.) from other ECUs.
TGS Lever assembly
The TGS communicates with TCU
(Transmission Control Unit), ECU,
ESP HECU and instrument cluster
to let the driver select the desired
transmission gear and to maintain
the desired driving condition. Also,
the tip switch is installed on the
lever knob and the steering wheel
so that the driver select the gear
manually when the shift lever is in
"M".Sensor cluster
The sensor cluster is linked to
the sensors on the unit board
and CAN interface. And they
are housed in one case and
mounted to the body.

01-10
A/T assembly
Automatic transmission is available as 4WD- and 2WD-type,
and provides 6 speeds for forward travel and 1 reverse
travel. It is also equipped with the torque converter with inner
lock-up clutch and electronically controlled solenoid which
controls all hydraulic functions.

PTU (Power Transfer Unit)
The PTU is a device that transfers the power
generated from the engine to the rear axle through
propeller shaft and E-coupling by changing the power

4WD vehicle.
Rear axle assembly
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 independentl
y
of each other with the universal joint and the slip
joint.
E-coupling control unit (E-Coupling ECU)
The E-coupling unit is a control unit which determines
the magnetic force by considering CAN signals (wheel
speed, engine torque, pedal opening, ABS/ESP CAN
signals, etc.) from other ECUs.

ECU
The ECU controls the electric
power steering system
depending on the driving
conditions, based on the
signals from the torque and
angle sensor.
2) EPS (Electric Power Steering)
Fuse
The vehicle with EPS has
EPS fuse (80A) mounted to
the positive (+) terminal of the
battery, and this fuse supplies
power to the EPS unit
directly..
Steering gear box assembly
When the driver turns the steering wheel, a torque is generated and the torque sensor and the steering
angle sensor in the EPS system detect the rotation of the steering column to run the electric motor. At
this time, the worm gear connected to the motor drives the helical gear mounted to the steering column
to generate the assist torque for the steering column. This allows the driver to operate the steering
wheel easier.

Colum shaft assembly
The column shaft assembly consists
of BLAC motor, ECU, torque and

steering (EPS) system uses the
electric motor to assist the steering
force. It functions independently
regardless of whether the engine is
running or not, unlike the existing
hydraulic power steering.
The lower shafts functions in the
same way as the hydraulic type.

3) Shift Map Selection
The driver can manually select between normal (S) and winter modes (W) via the mode switch.
Depending on the transaxle temperature, uphill and downhill grades and altitude, shift maps will be
selected by the TCU to suit the driving conditions. The following maps are available.
Standard (Normal) Mode ▶
Normal Mode is selected when the lever is in the D position with the mode switch in the normal (S)
position and the transaxle is within normal temperature ranges. Shift schedule points are optimised for
fuel efficiency and general driving conditions.
Uphill and Downhill Mode ▶
In this mode, depending on the load of the vehicle, adaptive shift maps are selected to progressively
adjust the shift points and torque converter lock points.
Altitude Mode ▶
Shift points are automatically adjusted at higher altitudes to compensate for changes in engine torque
where the torque produced by the engine is greatly reduced by the effects of reduced barometric
pressure and temperature.
Winter (W) Mode ▶
When winter mode is selected, starting in second gear is facilitated and the WINTER mode indicator
light is switched ON. To prevent wheel spin on slippery surfaces, the transmission will not allow first gear
unless manually overridden.

converter lock-up is increased to prevent heat generation by the torque converter.
Activation of the hot mode inhibits other transmission performance features including uphill and downhill
compensation and altitude compensation. Some degradation in shift feel may be experienced as the
torque converter is not unlocked during shifting.
Cruise Control Mode ▶
When cruise control is activated the engine ECU may request the transaxle to downshift under trailing
throttle conditions to increase engine braking.
Above 110℃the electrical radiator fans are switch ON
Above 130℃the engine torque will be reduced and the W light on the instrument cluster will flash
Above 200℃the transaxle will neutralise until the fluid tem
perature falls below 200°C as a final
protection.
