2) Inspection of Turbocharger
When problem occurs with the turbocharger, it could cause engine power decline, excessive discharge
of exhaust gas, outbreak of abnormal noise and excessive consumption of oil.
On-board Inspection 1.
Check the bolts and nuts foe looseness or missing
Check the intake and exhaust manifold for looseness or damage
Check the oil supply pipe and drain pipe for damages
Check the housing for crack and deterioration -
-
-
-
Inspection of turbine 2.
Remove the exhaust pipe at the opening of the turbine and check, with a lamp, the existence of
interference of housing and wheel, oil leakage and contamination (at blade edge) of foreign materials.
Interference: In case where the oil leak sign exists, even the small traces of interferences on the
turbine wheel mean, most of times, that abrasion has occurred on the journal bearing. Must
inspect after overhauling the turbocharger.
Oil Leakage: Followings are the reasons for oil leakage condition -
-
Problems in engine: In case where the oil is smeared on inner wall section of the exhaust gas
opening.
Problems in turbocharger: In case where the oil is smeared on only at the exhaust gas
outlet section. *
*
Idling for long period of time can cause oil leakage to the turbine side due to low pressure of exhaust
gas and the rotation speed of turbine wheel. Please note this is not a turbocharger problem.
Oil Drain Pipe Defect
In case where oil flow from the turbocharger sensor housing to the crank case is not smooth
would become the reason for leakage as oil builds up within the center housing. Also, oil thickens
(sludge) at high temperature and becomes the indirect reason of wheel hub section. In such case,
clogging and damage of the oil drain pipe and the pressure of blow-by gas within the crank case
must be inspected.
Damages due to Foreign Materials.
When the foreign materials get into the system, it could induce inner damage as rotating balance
of the turbocharger gets out of alignment. -

3) Inspection of Turbine
Thoroughly check the followings.
Must absolutely not operate the turbocharger with the compressor outlet and inlet opened as it
could damage the turbocharger or be hazardous during inspection.
Interference: In case where is trace of interference or smallest damage on the compressor wheel
means, most of times, that abrasion has occurred on the journal bearing. Must inspect after the
overhaul.
Oil Leakage: The reason for oil leakage at the compressor section is the air cleaner, clogged by
substances such as dust, causes the compressor inlet negative pressure. -
-
Rotating in high speed at no-load for extended period of time can cause oil leakage to the
compressor section as oil pressure within the center housing gets higher than pressure within
the compressor housing.
Overuse of engine break (especially in low gear) in down hill makes significantly low exhaust gas
energy compared to the time where great amount of air is required during idling conditions of the
engine. Therefore, amount of air in the compressor inlet increases but the turbocharge pressure
is not high, which makes negative a.
b.
No problem will occur with the turbocharger if above conditions are found in early stage but oil
leaked over long period of time will solidify at each section causing to breakout secondary defects.
Damages by foreign materials: In case where the compressor wheel is damaged by foreign materials
requires having an overhaul. At this time, it's necessary to check whether the foreign materials have
contaminated intake/exhaust manifold or inside of engine.

3. CAUTIONS AND WARNING FOR SAFETY
Ssangyong is not liable for any personal injury and material damage, caused by violation of traffic
regulations or neglect of observing actual traffic and driving situations.
Colors on display figures in this manual may differ from actual display due to publication concerns. -
-
Do not disassemble or modify this system.
If doing so, it may cause an accident, fire or electric shock.
Do not use the system if it is malfunctioning (sound or video output problem).
Doing so may lead to an accident or electric shock.
Please contact a Ssangyong service dealer immediately.
The system should be used only when the engine is started.
Using the system for an extended period of the with the engine off may discharge the battery.
Do not leave beverages or foreign materials around the system.
If they enter the system, they may cause a fire.
The system may break down if a disc not supported by this system is inserted.
Do not apply impact to or drop this system.
It might cause malfunction.
Never leave the system in a hot or cold place for an extended period of time. Therefore, do not park
the vehicle in a hot or cold place. The ambient temperature should be -30℃ ~ +80℃ for
proper operation. -

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.
ABS features an enhanced algorithm which includes control of the brake force distribution between the
front and rear axles. This is called Electronic Brake Distribution. In an unloading car condition the brake
efficiency is comparable to the conventional system but for a fully loaded vehicle the efficiency of the
EBD system is higher due to the better use of rear axle braking capability.
▶Advantages
Elimination of conventional proportioning valve EBD utilizes the existing rear axle wheel speed
sensor to monitor rear wheel slip.
Based on many variables in algorithm a pressure hold, increase and/or decrease pulsetrain may
be triggered at the rear wheels insuring vehicle stability.
Vehicle approaches the ideal brake force distribution (front to rear).
Constant brake force distribution during vehicle lifetime.
EBD function is monitored via ABS safety logic (conventional proportioning valves are not
monitorable). -

3) Important Notice
The modulators for production line are not filled with the brake fluid (dry type). But, for after service, they
are filled with the brake fluid (wet type).
Make sure to keep the procedures in service manual when bleeding the air from the brake lines.
Be familiar with the lamp ON conditions to provide the correct information and reliability to customers.
ECU monitors the valve and motor for ABS when the vehicle speed approaches 5 km/h. At this time,
you can hear the clattering noise. 1.

How to use the Top Tether ▶
The top tether anchors for securing the child
seat are located on the back side of second
row seat.
Remove the headrest from the second row
seat.
Place the child restraint on the second row
seat.
Connect the tether connector in child
restraint to the rear anchor. Securely tighten
the child restraint by adjusting the webbing of
the tether connector. -
-
-
-
The rear anchor is the supplemental device to secure the child restraint system after engaging it
by the lower latches. Therefore, do not secure the child restraint system only with the seatback
anchors. The increased load may cause the hooks or anchors to break, causing serious injury or
death.
If a child restraint is not properly secured to the vehicle and a child is not properly restrained in
the child restraint, the child could be seriously injured or killed in a collision. Always follow the
instructions provided by the manufacturer for installation.
Make sure the latches of the child restraint system are latched to the lower latches. In this case,
you can hear the “click” sound.
Incorrectly installed child restraint system may cause an unexpected personal injury.
Child restraint anchorages are designed to withstand only those loads imposed by correctly fitted
child restraints.
The tether strap may not work properly if attached somewhere other than the correct rear
anchor.
Rock the child restraint to check if it is securely installed. Refer to instructions provided by the
manufacturer of the child restraint.
Do not install the child restraint if it hinders the operations of front seat. -
