OPERATING PRINCIPLES The E-VGT is designed to get more improved engine power in all ranges by controlling the turbine as follows: 1) How it Works at Low Speed Normal turbocharger cannot get the turbo effect because the amount of exhaust gas is not enough and the flow speed is slow in a low speed zone, but VGT allows the flow passage of exhaust to narrow, resulting in increasing the flow speed of exhaust gas and running the turbine quickly and powerfully.
Page 267
06-22 2) How it Works at High Speed In a high speed zone, the amount of exhaust gas increases and it is accompanied with a great force. Therefore, if the inner diameter of venturi is more widened, the turbine in the turbocharger by the releasing force of abundant exhaust gas can deliver a more increased energy to the compressor.

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.
Page 305
12-6 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.
Page 306
12-7 8510-23 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.
Page 307
12-8 4) Recovery of Set Speed (RESUME) Even if the cruise control is cancelled, the previous set cruise speed can be recovered by pushing (Type A) or pulling (Type B) toward the cruise control lever when the current vehicle speed is over 36 km/h without an acceleration intervention.
Page 308
12-9 8510-23 5) Normal Cancellation of the Cruise Control The cruise control system will be canceled when one or more items of the following conditions are applied; When the brake pedal is depressed. When the cruising speed is downed less than 38 km/h. When the OFF switch is operated by pulling the cruise control lever (Type A) or by pushing the ON- OFF switch of the cruise control lever (Type B).

10-3 8510-23 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.
Page 409
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.
Page 410
10-5 8510-23 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.
Page 411
10-6 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.
Page 412
10-7 8510-23 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.
Page 413
10-8 4) Recovery of Set Speed (RESUME) Even if the cruise control is cancelled, the previous set cruise speed can be recovered by pushing (Type A) or pulling (Type B) toward the cruise control lever when the current vehicle speed is over 36 km/h without an acceleration intervention.
Page 414
10-9 8510-23 5) Normal Cancellation of the Cruise Control The cruise control system will be canceled when one or more items of the following conditions are applied; When the brake pedal is depressed. When the cruising speed is downed less than 38 km/h. When the OFF switch is operated by pulling the cruise control lever (Type A) or by pushing the ON- OFF switch of the cruise control lever (Type B).
Page 415
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.

09-13 4891-01 2) Operation of ESP System (1) Under steering ▶ What is understeering? Understeer is a term for a condition in which the steering wheel is steered to a certain angle during driving and the front tires slip toward the reverse direction of the desired direction. Generally, vehicles are designed to have understeer.
Page 660
09-14 (2) Over steering ▶ What is oversteering? Oversteer is a term of a condition in which the steering wheel is steered to a certain angle during driving and the rear tires slip outward losing traction. Compared to understeering vehicles, it is hard to control the vehicle during cornering and the vehicle can spin due to rear wheel moment when the rear tires lose traction and the vehicle speed increases.
09-15 4891-01 (3) ESP Control The ESP (Electronic Stability Program) has been developed to help a driver avoid danger of losing control of the vehicle stability due to understeer or oversteer during cornering. The yaw rate sensor, lateral sensor and longitudinal sensor in the sensor cluster and the steering wheel angle sensor under the steering column detect the vehicle conditions when the inner or outer wheels are spinning during oversteer, understeer or cornering.
Page 662
09-16 (4) Vehicle Control During Cornering The figure below shows the vehicle controls by the ESP system under various situations such as when the brake pedal is depressed or not depressed during cornering, when the ABS is operating and when braking without the ABS.

09-17 4891-01 3) HBA (Hydraulic Brake Assist System) (1) Purpose HBA (Hydraulic Brake Assist) system helps in an emergency braking situation when the driver applies the brake fast, but not with sufficient pressure, which leads to dangerously long braking distance. ECU recognizes the attempt at full braking and transmits the signal calling for full brake pressure from the hydraulic booster.
Page 664
09-18 (2) Operation The brake pressure value and the changed value of the pressure sensor are the conditions in which the HBA System operates. There are 2 pressure sensors under the master cylinder. When the ESP ECU system determines that emergency braking is present, the pump operates, the brake fluid in the master cylinder is sent to the pump and the braking pressure is delivered to the wheels via the inlet valves.
Page 665
09-19 4891-01 4) ARP (Active Roll-Over Protection) The ARP (Active Roll-over Protection) system is a safety assistant device that minimizes, by controlling brakes and the engine, the physical tendency of the vehicle rollover during sharp lane changes or U- turns. For the system, software is added to the existing ESP system and no additional device or switch is needed.
Page 666
09-20 During the ARP operation, vehicle safety (rollover prevention) takes the first priority and thus, stronger engine control is in effect. Consequently, the vehicle speed decreases rapidly, so the driver must take caution for the vehicle may drift away from the lane. The ARP function is still available even when turning off the ESP system by ESP OFF switch.
09-21 4891-01 4. SCHEMATIC DIAGRAM 1) Hydraulic Circuit Diagram When equipped with ABS, the braking force at each wheel will be controlled with 3-channel 4-sensor method. And when equipped with ESP, 4 wheels will be controlled independently with 4-channel method. (When controlling ABS system only, it will be operated with 3-channel method.) When compared to the vehicle equipped with ABS/EBD only, the internal hydraulic circuit has a normally-open separation valve and a shuttle valve in primary circuit and in secondary circuit.
Page 668
09-22 (1) Hydraulic Circuit Diagram When compared to the vehicle equipped with ABS/EBD only, the internal hydraulic circuit has a normally-open separation valve and a shuttle valve in primary circuit and in secondary circuit. When the vehicle brakes are not applied during engine running or when applying the non-ABS operating brakes, the normally-open separation valve and the inlet valve are open, whereas the normally-closed shuttle valve and the outlet valve are closed.
Page 669
09-23 4891-01 (2) Hydraulic Circuit of HBA The above figure shows one front and one rear wheel and the same hydraulic circuit forms as in the ESP operation. When HECU recognizes that it is an emergency and it is required for hard braking, depending on the pressure value of the brake pressure sensor and pressure changes caused by the pressure sensor timing, it operates the pump immediately to apply the brake pressure at the wheels.
Page 670
09-24 (3) Hydraulic Circuit Diagrams in Conditions ▶Idling and Normal Braking Condition In this position, the separation valve and the inlet valve are open (normal open), the electrically operated shuttle valve and the outlet valve are closed. When the brake is applied under these conditions, the brake fluid will be sent to each wheel via the separation valve and inlet valve.
Page 671
09-25 4891-01 ▶DUMP (ESP is working) Mode The pressure decreases just before the wheel speed drops and the wheels are locked. The inlet valve closes and the outlet valve opens as in the ESP HECU and the oil is gathered at the low pressure chamber while no additional oil is being supplied.
Page 672
09-26 ▶HOLD (ESP is working) Mode The Inlet valve and outlet valve will be closed to maintain the pressure in the hydraulic circuit applied at the wheels. By closing the valves, the hydraulic pressure at the wheels will not be lost or supplied any more.
Page 673
09-27 4891-01 ▶RISE (ESP is working) Mode The shuttle valve and inlet valve will be open and the separation valve and outlet valve will be closed. Then, the pump is operated. When ESP operates while the ABS is operating, the pressure will be increased continuously until just before the corresponding wheel gets locked.
10-3 4891-01 1. SYSTEM OVERVIEW When braking suddenly or braking on slippery roads, the vehicle keeps moving forward but the wheels are locking and not rotating. If these happen, the vehicle may lose stability or rotate resulting in an accident. ABS helps to maintain directional stability and control of the vehicle. ABS is designed to secure more safety and increase the control of steering wheel during emergency braking situation.
Page 677
10-4 2) Maximum Brake Force FBmax = wheel load FR x coefficient of friction (Mh) The braking process cannot be described sufficiently accurately with the brake forces calculated. The values calculated only apply if the wheel is not locked. In the case of a locking wheel, the static friction turns into lower sliding friction, with the result that the stopping distance is increased.
10-5 4891-01 2. COMPONENTS AND LAYOUT The basic functions of ABS system are same with previous version. However, the wheel speed sensing type is different from previous version. Front Active Wheel Speed Sensor Rear Active Wheel Speed Sensor ABS HECU Warning Lamps EBD warning lamp ABS warning lamp...
10-7 4891-01 2) EBD (Electronic Brake Force Distribution) System ▶System description As an add-on logic to the ABS base algorithm, EBD works in a range in which the intervention thresholds for ABS control are not reached yet. EBD ensures that the rear wheels are sensitively monitored for slip with respect to the front axle. If slip is detected, the inlet valves for the rear wheels are switched to pressure hold to prevent a further increase in pressure at the rear-wheel breaks, thus electronically reproducing a pressure-reduction function at the rear-wheel brakes.
10-8 4. HYDRAULIC CIRCUIT DIAGRAM 1) Hydraulic Circuit of ABS The vehicle equipped only with the ABS controls the wheel’s braking force using three 3- channel 4-sensor method. The front wheels that are the primary circuit of the brake system is composed of two wheel speed sensors and two channel valves system with two inlet valves and two outlet valves.
Page 682
10-9 4891-01 2) ABS Circuit Per ABS Operation Range ▶Hydraulic Pressure Circuit when ABS is Not Operating The hydraulic pressure in the master cylinder increases through the vacuum booster and it is delivered to the wheel via the normal open inlet valve. At this moment, the normally-closed outlet valve is closed. The speed of the wheel that hydraulic pressure is delivered reduces gradually.
Page 683
10-10 ▶Pressure Decreases in the Circuit when ABS is Operating Even when the hydraulic pressure on each circuit is stable, the wheel can be locked as the wheel speed decreases. This is when the ABS ECU detects the wheel speed and the vehicle speed and gives the optimized braking without locking the wheels.

Page 692
11-10 ▶ Air Bleeding The air bleeding should be done after servicing the power steering system and when the difference between two measurements (cooled and normal temperature) is prominent. Lift up the vehicle very carefully. Turn the steering wheel to its both ends several times and add the oil up to MAX line in the steering oil reservoir.
Page 693
11-11 4610-00 ▶ Oil Pump Pressure Check Check the oil pump pressure to locate any defect in oil pump. Before checking the pressure, check the oil level and belt tension. Prepare the empty container to collect the spilled oil during the service.
Page 694
11-12 Measure the oil pressure with the gauge valve fully open. Pressure at no load 3 ~ 5 bar If the pump pressure is in specified range, the pump is normal. If not, replace the power steering pump Turn the steering wheel right or left until it stops with the engine idling and valve fully open.

12-7 4170-01 2. ABNORMAL TIRE SYMPTOM 1) Standing Wave 35 psi Specified tire inflation pressure During driving, the rotating tire repeats deformation and restoring movement in is tread. This happens when the tire pressure is low in high speed driving. However, when the wheel rotating speed is fast, the tire is deformed even before it is restored to its original shape and the trembling wave appears on the tread portion.
Page 703
12-8 2) Hydroplaning When the vehicle is driven on a road surface covered with water at high speed, tires do not contact with the road surface but rotate floating on a thin film of water. It causes brake failure, lower traction force and losing the steering performance. To prevent this, increase the tire inflation pressure, use tires with leaf shape tread which is not worn.
12-9 4170-01 3. WHEEL BALANCE If weight is not equally distributed around the wheel, unbalance centrifugal force by the wheel rotation produces vibration. As the centrifugal force is produced proportional to the square of the rotating speed, the wheel weight should be balanced even at high speed. There are two types of the tire and wheel balancing: static and dynamic.
