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. -

1) Coolant Level Check
Park the vehicle on level ground and apply the parking brake. Stop the engine and wait until it is
cooled down.
The coolant level should be between the MAX and MIN mark on the coolant reservoir.
Check the coolant level. If the level is below the “MIN” mark, immediately add coolant. 1.
2.
Scalding hot coolant and steam could be blown out under pressure, which could cause serious
injury. Never remove the coolant reservoir cap when the engine and radiator are hot.
Avoid any direct contact of the coolant to the painted body of the vehicle. -

4) Operation
Glow plug is installed in the cylinder head. It enhances the cold starting performance and reduces the
exhaust gas during cold starting.
ECU receives the data (engine rpm, coolant temperature, vehicle speed) through CAN lines. Based on
the data, GCU controls the pre-glow, cranking and post-glow. It also checks the glow plugs, and sends
the result to ECU.
(1) Temperature/Current Properties of GCU
GCU increases the temperature of glow plug very rapidly (approx. 2 seconds up to
1000°C)
FETs (similar to transistor) for each cylinder are integrated in GCU. During the pre-glow
period, battery voltage is supplied to the glow plugs directly to heat them rapidly.
After getting the desired temperature by pre-glowing, the temperature is controlled by duty
ratio. Step 1:
Step 2 & 3:
Step 4:
This shows the supplying voltage and time by GCU in each step. The step 4 is the period to keep
the temperature. -Step 1: I1
Step 2: I2
Step 3: I3
Step 4: I4

1. CAUTIONS
1) Standard pattern of soot accumulation
Abnormal Soot Accumulation ▶
Normal Soot Combustion ▶
Cautions to protect the catalyst filter ▶
Use the designated fuel only.
Observe the recommended service intervals of engine oil.
Check the engine oil level frequently and add if necessary.
Do not idle the vehicle unnecessarily.
Do not turn off the engine while the vehicle is running.
Do not shift the gear selector lever to neutral when going downhill.
Do not use improper engine oil or fuel additives.
Do not drive for a long time when the warning lamp is illuminated.
Make sure no flammable material, such as dry grass or tissue paper, contacts with the catalyst filter
while the vehicle is parked.
For the vehicles used in urban traffic, driving on the expressways for more than 1 hour at least once
per week is needed so that the PM inside CDPF isn't collected to one side only. -

Overload of CDPF

5) Warning Lamp Related to CDPF
CDPF regeneration process (warning lamp NOT illuminated) ▶
The CDPF system enters the regeneration mode
when the driving distance becomes approx. 600 to
1,200 km (may differ by the driving condition and
driving style). Then, the engine ECU performs the
CDPF regeneration operation. However, the driver
is not informed with this operation by any engine
warning lamp or vehicle signal, so he/she may not
detect this operation. The control logic at the post-
injection dur-ing the regeneration process is to
increase the fuel injection volume and control the
intake air volume (by the throttle body) in order to
increase the temperature of the exhaust gas. The
driver may not feel any particular difference from
the vehicle.
If the CDPF cannot reach the regeneration
temperature due to low speed driving or other
reason during the regeneration process, the soot is
continuously accumulated in the CDPF. W hen this
condition continues and the CDPF is overloaded
with soot, the engine warning lamp blinks to inform
this situation to the driver.
In order to solve this problem, drive the vehicle at a
speed of approx. 80 km/h for 15 to 20 minutes to
perform the CDPF regeneration process.
If the engine warning lamp on the instrument
cluster blinks, the CDPF is overloaded. In this
case, perform the step 2. 1.
2.
3.If the vehicle is driven at a speed of 5 to 10 km/h
for an extended period of time, the soot
accumulated in the CDPF cannot be burned as the
CDPF cannot reach the regeneration temperature.
Then, an excessive amount of soot can be
accumulated in the CDPF.
This case is much worse than the simple over-load
of the CDPF. To inform this to the driver, the
engine warning lamp comes on and the engine
power is decreased to protect the system.
To solve this problem, blow soot between the
engine and exhaust system several times and
erase the related DTC. Then, check if the same
DTC is regenerated again. If so, check the DTC
related to the differential pressure sensor. 1.

D. Bypass control for EGR cooler
Cooler temperature ▶
When the coolant temperature is below 70℃, the exhaust gas is bypassed the EGR cooler.
Exhaust gas temperature ▶
When the exhaust gas tem
perature is below 300℃, the exhaust gas is bypassed the EGR cooler
Otherwise, PM could be increased due to too low exhaust gas temperature.
E. Control elements for EGR system
Accelerator pedal (engine load) - Indicates the driver's intention and engine load. If the load goes
up, the EGR ratio is decreased.
T-MAP (boost pressure map stored in ECU) - Compensates the difference in boost pressure by
adjusting EGR ratio.
Engine rpm - Used as the signal for determining EGR operating range.
Coolant temperature - When the coolant temperature is low, NOx is decreased but PM could be
increased. So, to reduce PM, decrease EGR ratio when the coolant temperature is low.
Intake air mass and temperature - HFM sensor measures the intake air mass to calculate the
actual EGR volume. If the air mass is larger than programmed value in map, EGR ratio will be
higher.
EGR position sensor - Detects the actual opening angle of EGR valve and performs feedback
function according to PWM control by ECU.
Wide band oxygen sensor - Detects the oxygen volume in exhaust gas to check if the EGR ratio is
proper.
Electronic throttle body - Keeps EGR ratio to optimized level by controlling the throttle body in EGR
operating range (decreasing pressure in intake manifold). -

(14) Immobilizer control
A. Overview
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is
turned to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if
correct, allows the vehicle to start the engine.
