Abnormal changes of the gear selector lever can damage the yyengine. Do not move the gear shift
lever to Neutral while driving at the set speed. Automatic transaxle damage may result.
The speed that has been set may not be maintained on uphill or yydownhill slopes.
The speed may drop to less than the set speed on a steep uphill yygrade. 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 yydownhill grade. When the speed
increases too much, turn off the cruise control. 1.

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
Ssangyong Dealer for diagnosis of the cruise control system.
(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.

2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston speed and
crankshaft angle based on input data and stored specific map to control the engine power and emission
gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure and
activates injector solenoid valve to control the fuel injection period and injection timing; so controls
various actuators in response to engine changes. Auxiliary function of ECU has adopted to reduce
emission gas, improve fuel economy and enhance safety, comforts and conveniences. For example,
there are EGR, booster pressure control, autocruise (export only) and immobilizer and adopted CAN
communication to exchange data among electrical systems (automatic T/M and brake system) in the
vehicle fluently. And Scanner can be used to diagnose vehicle status and defectives.
water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied instantly
so there is injector drive circuit in the ECU to generate necessary current during injector drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and hold-
current-phase and then the injectors should work very correctly under every working condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper injection
volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and engine
cranking speed. Starting injection continues from when the ignition switch is turned to ignition
position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel and
engine rpm and the drive map will be used to match the drivers inputs with optimum engine power. -

Pilot injection timing control
The pilot injection timing is determined as a function of the engine speed and of the total flow.
The elements are:
A first correction is made according to the air and coolant temperatures. This correction allows the
pilot injection timing to be adapted to the operating temperature of the engine.
A second correction is made according to the atmospheric pressure. This correction is used to adapt
the pilot injection timing as a function of the atmospheric pressure and therefore the altitude. -
-
d. Fuel Control
1. Main Flow Control
The main flow represents the amount of fuel injected into the cylinder during the main injection. The pilot
flow represents the amount of fuel injected during the pilot injection.
The total fuel injected during 1 cycle (main flow + pilot flow) is determined in the following manner.
When the driver depress the pedal, it is his demand which is taken into account by the system in order
to determine the fuel injected.
When the driver release the pedal, the idle speed controller takes over to determine the minimum fuel
which must be injected into the cylinder to prevent the enigne from stalling.
It is therefore the greater of these 2 values which is retained by the system. This value is then compared
with the lower flow limit determined by the ESP system.
As soon as the injected fuel becomes lower than the flow limit determined by the ESP system, the
antagonistic torque (engine brake) transmitted to the drive wheels exceeds the adherence capacity of
the vehicle and there is therefore a risk of the drive wheels locking.
The system thus chooses the greater of these 2 values (main flow & pilot flow) in order to prevent any
loss of control of the vehicle during a sharp deceleration.
As soon as the injected fuel becomes higher than the fuel limit determined by the ASR trajectory control
system, the engine torque transmitted to the wheels exceeds the adhesion capacity of the vehicle and
there is a risk of the drive wheels skidding. The system therefore chooses the smaller of the two values
in order to avoid any loss of control of the vehicle during accelerations.
The anti-oscillation strategy makes it possible to compensate for fluctuations in engine speed during
transient conditions. This strategy leads to a fuel correction which is added to the total fuel of each
cylinder.
The main fuel is obtained by subtracting the pilot injection fuel from the total fuel.
A mapping determines the minimum fuel which can control an injector as a function of the rail pressure.
As soon as the main fuel falls below this value, the fuel demand changes to 0 because in any case the
injector is not capable of injecting the quantity demand. A switch makes it possible to change over from the supercharge fuel to the total fuel according to the
state of the engine.
Until the stating phase has finished, the system uses the supercharged fuel.
Once the engine changes to normal operation, the system uses the total fuel. -

Key approval process in Smart key system equipped vehicle
The key approval consists of two processes; immobilizer key approval and Smart key
approval.
Immobilizer key approval: When inserting the Smart key into Smart key slot, the power is supplied to the
key slot. SKM communicate with the Smart key in key slot to check if it has valid crypto code. If it is valid,
ECU start to control the engine when pressing the Engine Start/Stop button. The system has 10
seconds of valid time-out period. If the engine does not start in this period, the key approval process
should be done again.
Smart key approval: When pressing the Engine Start/Stop button or depressing the brake pedal without
Smart key inserted into the key slot, SKM communicate with the Smart key to check if it has valid crypto
code. If it is valid, the engine can be started.

3) General Instructions
Before lifting up the vehicle with a lift, correctly support the lifting points.
When using a jack, park the vehicle on a level ground and place the wheel chocks under the tires.
Position the jack under the frame and lift up the vehicle and then support with chassis stand before
service work.
Make sure to disconnect the negative (-) cable from the battery to prevent any damage to electric
systems.
If you have to work on vehicle, cover the seats and floor with protection covers to avoid any
damage and contamination.
Brake fluid and anti-freeze can damage the painted surface of body. So carefully handle them
during service work.
To improve the efficiency of service work, use only recommended and specified tools.
Use only Ssangyong genuine spare parts.
Never reuse the cotter pin, gasket, O-ring, oil seal, lock washer and self-locking nut. Replace them
with new ones. If reused, normal functions cannot be maintained.
Store the disassembled parts as a set based on disassembly order and unit.
Pay particular attention not to miss or mix the fasteners.
If necessary, especially for inspection, clean the removed parts completely.
Apply the oil or grease on the running and sliding surfeces before installation. Use the specified
sealant and gasket to prevent leakage if necessary.
Tighten the fasteners to the specified tightening torque.
As a final stage of service work, check if the serviced system is working properly and the problem
has been eliminated clearly. (1)

-
(3) Exhaust system
Be aware to any changes in sound or smell from the exhaust system. These may be caused by leak or
overheat. Have the exhaust system checked and repaired immediately.
Inspect the exhaust system including catalytic converter. Inspect all the components and body frame
near the exhaust system. -
-
(4) Tires
Unusual vibration of the steering wheel and seats or pulling to one side on the straight and level roads
may indicates the uneven tire inflation pressure or poor wheel balance. -
(5) Steering and suspension system
Inspect the front and rear suspension and the steering system for damage, looseness or missing
parts, signs of wear or lack of lubrication. Inspect the power steering line and the hoses for
connection, leak, crack and chafing. Inspect the drive axle boot and seals for damage, tear or leak.
Replace or repair the system if necessary. -
(6) Engine oil
Check the oil level when the engine is still warm and add the specified engine oil if necessary. -
