A. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine operating
conditions. The water pump draws the coolant from the radiator. The coolant then circulates through
water jackets in the engine block, the intake manifold, and the cylinder head. When the coolant
reaches the operating temperature of the thermostat, the thermostat opens. The coolant then goes
back to the radiator where it cools. The heat from automatic transmission is also cooled down through
the radiator by circulating the oil through the oil pump. ECU controls the electric cooling fans with three
cooling fan relays to improve the engine torque and air conditioning performance.
For detailed information, refer to Chapter "Air Conditioning System".

1. CRUISE CONTROL SWITCH
The cruise control is an automatic speed control system that maintains a desired driving speed without
using the accelerator pedal.
The vehicle speed must be greater than 36 km/h to engage the cruise control. This feature is
especially useful for motorway driving.
The cruise control system is a supplementary system, which helps the driver to drive the vehicle at
a desired speed without using the accelerator pedal under the traffic condition where the vehicle-to-
vehicle distance meets the legal requirement.

(2) Using the Cruise Control on Hills
How well the cruise control works on hills depends on the speed, load, and the steepness of the hill.
When going up steep hills, you may have to depress the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to a lower gear to keep your speed down.
Applying the brake takes you out of the cruise control.
And the cruise control system cannot be operated again in driving state. In this case, you should stop
the vehicle, and turn off the ignition switch and then turn it on again. After you do that, you can use the
cruise control s
ystem again. But if the cruise control system isn’t recovered, you should contact
a Ssangyong Dealer for diagnosis of the cruise control system.
Abnormal changes of the gear selector lever can damage the engine. Do not move the gear shift
lever to Neutral while driving at the set speed. Automatic transmission damage may result.
The speed that has been set may not be maintained on uphill or downhill slopes.
The speed may drop to less than the set speed on a steep uphill grade. The accelerator must be
used if you want to maintain that speed.
The speed may increase to more than the set speed on a steep downhill grade. When the speed
increases too much, turn off the cruise control. -

(1) Abnormal Cancellation of the Cruise Control
When the rapid deceleration is applied without braking.
When the rapid acceleration is applied without acceleration pedal intervention.
When the cruise control lever is failed.
When the brake switch and the brake light switch input signal are implausible. 1.

▶ Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed and INT
VOLUME when the ignition switch is in “ON” position and the INT switch is in “ON”
position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch to
“ON” position with the engine running or starting the engine with the INT switch positioned
“ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -

-
2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the table in
next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·

▶Auto Door Lock
The door lock system outputs "LOCK" when the vehicle speed maintains over 50 km/h. However, it
doesn't output "LOCK" when all doors are locked or failed.
If any of doors is unlocked after outputting "LOCK" in step 1, outputs "LOCK" up to 5 times (except
step (1)) at the interval of one second.
If any of doors is unlocked after 5 times of "LOCK" outputs, the door(driver's/passenger's/
rear) is regarded as "FAIL".
If the door that was regarded as fail is changed(UNLOCK to LOCK), it will be recognized as a
normal one.
If any door is regarded as FAIL, the auto door lock function does not work. (if it is occurred when the
vehicle speed is over 50 km/h, the auto door lock output does not occur even if the vehicle speed
falls below 50 km/h and accelerates again to over 50 km/h.) Nonetheless, the central door lock
function works properly.
When the system receives "UNLOCK" signal from a door switch, it outputs "LOCK" signals 5 times.
If additional "LOCK" signal from another door switch is detected during the period, the system
outputs five "LOCK" signals 5 times for the switch.
The door lock system outputs "UNLOCK" automatically if the "LOCK" output conditions are
established by this function or the key is cycled(IGN=OFF) (even when there is no "LOCK" output
while the vehicle speed maintains over 50 km/h under lock condition). (If the LOCK condition is
established with the ignition switch ON, the system outputs UNLOCK signal unconditionally when
turning the ignition switch to OFF position.) However, when the ignition key is turned to "OFF"
position, the lock output conditions will be cancelled.
The "FAIL" condition of the door will be erased when the ignition key is turned to "OFF" position. 1.

(3) Auto Light Function
The lights automatically come on and off according to the ambient brightness when the
multifunction light switch is in “AUTO” position while the ignition key is in “ON” position. 1.
(4) Auto Door Lock
The doors are locked and the theft deterrent mode is activated again if any of doors is not opened
after unlocking them with a REKES key.
Sends the message in 5 seconds after locking the doors automatically. 1.

The rain sensing wiper unit in this vehicle doesn’t control the wiper directly.
The rain sensing unit detects the amount of rain drops and sends the operating signal to STICS, and
STICS drives the wiper directly.
1. SYSTEM LAYOUT AND OVERVIEW
Rain sensing unitMultifunction wiper switch:
AUTO and sensitivity control
A sensor that emits infrared rays through LED
and then detects the amount of rain drops by
receiving reflected rays against sensing
section(rain sensor mounting section on the
windshield)with photodiode. AUTO
: Wiper operates automatically by rain sensor
FAST <-------> SLOW
: Auto delay/Auto speed control. A position
that can control sensitivity against rains on
the windshield and transmits wiping demand
signal accordingly.
Emitter lens
The LED which is located
at bottom emits the
infrared rays and the lens
guides the infrared rays to
target point.

2. RAIN SENSOR OPERATION
The rain sensor is installed on the specific heat treated windshield that has minimum 13% of
transmittance rate with specified intensity of radiation. It is installed on the glass with a adhesive of
Sorepa.
It communicates with STICS and makes the wipers to operate automatically under the rain sensing
mode (multifunction switch wiper: AUTO mode).
The emitting section of the rain sensor unit emits infrared rays against the windshield and then detects
the amount of rain drops by receiving reflected rays with photodiode.
The sensing section on the windshield is located just above the center point between LED and
photodiode.
