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.

(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 (DSL only).
When the cruise control lever is failed (DSL only).
When the brake switch and the brake light switch input signal are implausible. 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. -

1. OVERVIEW
1) System Description
The cruise control is an automatic speed control system that maintains a desired driving speed without
using the accelerator pedal. The cruise control switch is under the right side of steering wheel and
The vehicle speed must be greater than 38 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) Traffic Conditions for Using Cruise Control
Use the cruise control system only when the traffic is not jammed, driving on motorways or highways
where there is no sudden change in the driving condition due to traffic lights, pedestrian, etc.
Improper use of the cruise control could be dangerous.
Do not use on winding roads.yy
Do not use in heavy traffic.yy
Do not use on slippery, wet roads. -

This could result in a loss of control, collision, and/or personal injuries.
The described speed value may vary slightly depending on the road conditions.

2. CONFIGURATION
1) Circuit Diagram
The engine ECU detects the operating conditions of cruise control system, and monitors the braking
performance, vehicle speed, road conditions and ESP system operation. If the engine ECU determines
that there are not any problem to drive in cruise control mode, the vehicle can be operated by cruise
switch signals (decelerating, accelerating, cruising).

3. OPERATION
1) Setting a Desired Speed
To operate the cruise control, accelerate to the desired speed, which must be more than 38 km/h (24
MPH) and less than 150 km/h (90 MPH). In the vehicle equipped with manual transaxle, the gear shift
lever should be in 3rd (GSL: 2nd) or higher gear position.
Diesel engine equipped vehicle: When the desired speed is reached, press CRUISE ON (3) switch of
cruise control lever.
Gasoline engine equipped vehicle: When the desired speed is reached, press CRUISE ON (3) switch
of cruise control lever. The system is readyreadyreadyready to activate the cruise control function. To
activate the cruise control function, push up (1) the ACCEL switch of the cruise control lever.
Now, the vehicle is cruised by this system with the set speed.
And you can set to other vehicle speeds again with above steps after an accelerator pedal intervention
during the cruise control running. 1.

4.
Never use the cruise control system until you get used to it.
Improper use or not fully aware of this function could result in collision and/or personal injuries.

2) Accelerating with the Cruise Control System
(1) While the cruise control system is running
Push up the ACCEL switch of the cruise control lever and hold it until the desired speed is reached
without an accelerator pedal intervention.
When the desired speed is reached, release the lever. 1.
2.
(2) While the cruise control system is not running
Accelerate using the accelerator pedal over 38 km/h.
Push up the ACCEL switch of the cruise control lever and hold it.
And then release the accelerator pedal slowly.
When the desired speed is reached, release the lever. 1.

(3) Tap-up while the cruise control system is running
Push up the ACCEL switch of the cruise control lever less than 0.5 second per one switching while the
cruise control system is running. This is a tap-up switching.
When you operate a tap-up switching, the vehicle is accelerated by 1.0 km/h over the previous set
speed.
If you want to accelerate to 10 km/h, operate the tap-up switching ten times without accelerating with
the cruise control system. 1.

3) Decelerating with the Cruise Control System
(1) While the cruise control system is running
Push down the DECEL switch of the cruise control lever and hold it until the desired speed is reached
without a brake pedal intervention. But the cruise control system cannot maintain the cruise function at
less than 38 km/h.
When the desired speed is reached, release the lever. 1.
2.
(2) When the cruise control system is not running
Push down the DECEL switch of the cruise control lever and hold it.
And then release the accelerator pedal slowly.
When the desired speed is reached, release the lever. But the cruise control system cannot maintain
the cruise function at less than 38 km/h.1.

(3) Tap-down while the cruise control system is running
Push down the DECEL switch of the cruise control lever less than 0.5 second per one switching while
the cruise control system is running. This is a tap-down switching.
When you operate a tap-down switching, the vehicle is decelerated by 1 km/h below the previous set
speed.
If you want to decelerate to 10 km/h, operate the tap-down switching ten times without the brake
pedal intervention. 1.
