(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. -

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.
Operating temperature range of ECU is normally -40 to +85°C and protected from factors like
oil, 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. 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.

10-4
1) 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.
- Do not use in heavy traffic.
- 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. HOW TO OPERATE CRUISE CONTROL SWITCH
1) Setting a Desired Speed
To operate the cruise control, accelerate to the desired speed, which must be more than 36 km/h
(23 MPH) and less than 150 km/h (90 MPH).
When the desired speed is reached, push up the ACCEL switch of the cruise control lever or push
down the DECEL switch for 1 second per one switching and then release the accelerator pedal
slowly.
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.

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.
(1) Manual transmission equipped vehicle
The cruise control is only available when the 3rd or higher speed gear is engaged.

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 36 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 1.3 km/h over the previous set
speed.
If you want to accelerate to 13 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 34 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 34 km/h. 1.
2.
3.
(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 1.0 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.
