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
To decrease the vehicle speed with the cruise control system when the system is not running, follow the
procedures below.
Push down the cruise control switch lever to DECEL side and hold it until the desired speed is
reached while the vehicle speed is over 36 km/h.
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.

(3) Tap-down while the cruise control system is running
To decrease the vehicle speed in stages while the cruise control system is running, follow the
procedures below.
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 for 1.0 km/h below the previous set speed.
If you want to decelerate for 10 km/h, operate the tap-down switching ten times without the brake pedal
intervention. 1.

4) Recovery of Set Speed (RESUME)
Even if the cruise control is cancelled, the previous set cruise speed can be recovered by pulling up the
cruise control lever when the current vehicle speed is over 36 km/h without an acceleration intervention.
But if you turn off the ignition switch, the memorized set speed is cleared and you cannot recover the
previous set speed.
But the driver should know the previous set speed to react to the changed vehicle speed properly. If the
vehicle speed increases abruptly, depress the brake pedal to adjust the vehicle speed properly.

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 or When ESP is activated.
When the cruising speed is downed less than 34 km/h
When applying the parking brake during driving.
When using the clutch in order to shift (M/T only). 1.

4.
Keep the main cruise control switch in the neutral position when not using the cruise control.

Do not move the shift lever to Neutral position while driving with the cruise control turned on.
Otherwise, it may result in system malfunction or accidents.
Always be prepared to use the brake or accelerator pedal for safe driving while the cruise control
system is running.
The actual speed can be different from the set speed momentarily when driving on a uphill or
downhill. So, it is recommended to disable the cruise control function on a uphill or downhill. hen
driving on a steep hill use the engine brake and foot brake properly to protect the vehicle system
and for a safe driving.
Ensure that the safe distance is maintained and use the brake pedal if needed. 1.

4.
(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.
When the cruise control lever is faulty.
When the brake switch and the brake light switch input signal are implausible. 1.
2.
3.
When the cruise control function is cancelled abnormally or intermittent problems occur, stop the vehicle
and turn off the ignition switch and remove the key to reset the system. After a while, turn on the ignition
switch again to operate the cruise control system.

3. ENGINE COMPARTMENT LAYOUT
Do not work on the engine compartment while the engine, radiator, exhaust manifold, muffler or
catalytic converter is hot. Always turn the engine off and allow it to cool before starting the
maintenance.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine. -

3. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value
Compression ratio16.5 : 1
Test condition
Compression pressureStandard32 bar
Minimum18 bar
Differential limit between cylindersMaximum 3 bar
The compression pressure test is to check the conditions of internal components (piston, piston ring,
intake and exhaust vale, cylinder head gasket). This test provides current engine operating status.
Before cranking the engine, make sure that the test wiring, tools and persons are keeping away
from moving components of engine (e.g., belt and cooling fan).
Park the vehicle on the level ground and apply the parking brake.
Do not allow anybody to be in front of the vehicle. -

Measurement
Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
Remove the air cleaner duct and glow plugs. -

Place the diagram sheet to compression
pressure tester and install it into the plug hole. 1.

Brake booster and naster
cylinderVacuum pump
Pump capacity: 210 cc/rev
Camshaft speed: 375 to 3,000 rpm
Lubrication temperature: -40 to
Oil: 5W30
Drive type: Driven by exhaust
Camshaft sprocket
2. VACUUM PUMP
Vacuum pump generates the vacuum pressure and supplies it to EGR cooler bypass solenoid. This
pump is single vane type and displacement is 210 cc/rev. The lubrication oil is supplied through the hole
in hollow shaft.
Components
EGR cooler bypass valve
This valve is controlled by ECU.
When the engine is cooled, the
exhaust gas goes to combustion
chamber without passing through
EGR cooler because the valve is
closed by vacuum pressure.

2. MAINTENANCE
1) Level Check
Park the vehicle on a level ground and apply the parking brake. Stop the engine and wait more than 5
minutes.
Pull out the dipstick and wipe it with a clean cloth. Reinsert it all the way.
Pull out it again and check the oil level.
The oil level should be between the maximum (Max) mark and minimum (Min) mark on the oil dipstick.
Oil should be replenished before the level goes below the minimum mark. -
-
-
Operating vehicle with insufficient amount of oil can damage the engine. Make sure the engine oil
level is correct and add oil if necessary.
2) Replenishment
If the level gets to the lower point, open the filler cap on top of the cylinder block and add the genuine oil
without exceeding the level of the upper mark.
Recheck the oil level after 5 minutes.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine.
The oil should not go above the upper mark on the dipstick.
The engine oil may be consumed more if the engine is new. -
