The variable swirl valve actuator operates when
turning the ignition switch ON/OFF position to
open/close the swirl valve. In this period, the soot
will be removed and the learning for swirl valve
position is performed.
Swirl valve
Swirl: This is the twisted (radial) air flow along the cylinder wall during the intake stroke. This
stabilizes the combustion even in lean air-fuel mixture condition.
3) Features
Swirl and air intake efficiency
To generate the swirl, the intake port should be serpentine design. This makes the resistance in air
flow. The resistance in air flow in engine high speed decreases the intake efficiency. Eventually, the
engine power is also decreased, Thus, the swirl operation is deactivated in high speed range to
increase the intake efficiency.
Relationship between swirl and EGR
To reduce Nox, it is essential to increase EGR ratio. However, if EGR ratio is too high, the PM also
could be very higher. And, the exhaust gas should be evenly mixed with newly aspired air. Otherwise,
PM and CO are dramatically increased in highly concentrated exhaust gas range and EGR ratio
could not be increased beyond a certain limit. If the swirl valve operates in this moment, the limit of
EGR ratio will be higher. -

4) Relationship between swirl and fuel injection pressure
The injector for DI engine uses the multi hole design. For this vehicle, there are 8 holes in injector. If the
swirl is too strong, the injection angles might be overlapped and may cause the increased PM and
insufficient engine power. Also, if the injection pressure is too high during strong swirl, the injection angles
might be overlapped. Therefore, the system may decreases the fuel injection pressure when the swirl is
too strong.

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.

Sharp acceleration or deceleration
- 50 km/h faster than set speed
- 25 km/h faster than set speed for one minute
- 70 km/h slower than set speed
- 65 km/h slower than set speed for 3 minutes
When the cruise control lever is faulty.
When the brake switch and the brake light switch input signal are implausible. 1.

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.

4) Operating Process By Power Supply
(1) Rear wiper relay
(2) Rear fog lamp relay
The rear wiper motor relay is turned on when the rear wiper switch is turned on with the ignition key ON.
This relay is turned off when the rear wiper switch is turned off.
The power is supplied to the ICM no. B6 connector through the SB4 and no. 39.
The power for the rear fog lamp relay is supplied through the memory fuse in the engine compartment
CE box and fuse no. 52 in the interior IP box. This relay is controlled (ON/OFF) by the relay operation
signal which is connected to the no. A11 of the BCM.
The rear fog lamp is turned on when the rear fog lamp switch is turned on with the headlamp turned
on (i.e. IGN2 switch ON).
Turning on the rear fog lamp switch again when the relay is activated turns off the fog lamp.
The rear fog lamps do not come ON when the IGN2 switch is turned to OFF position or the light
switch is OFF.
The rear fog lamp should not automatically come on again if it has been turned off by any methods
other than the rear fog lamp switch. 1.

Rain sensor coupled wiper (LIN) ▶
System layout 1.
Data recognition & operation 2.
Data recognition time
The system performs LIN communication regardless of the conditions of wiper and light switch when
the ignition switch is in ON position. If the intermittent/automatic wiper switch is in "AUTO" and the
light switch is in "AUTO" position, the wiper system operates according to the LIN data.
The data received from the rain sensor is recognized for 2 times consecutively.
Operation when recognizing data
No data: wiper low/high relay OFF
Low speed signal: low relay ON (ON for at least one cycle), but high relay OFF
High speed signal: high relay ON (ON for at least one cycle), but low relay OFF
The washer switch signal is overridden during continuous operation of the wiper.
(Washer coupled wiper function is available only during intermittent operation) -

16) Time Lag Power Window Control
When turning the ignition switch to ON position, the power window relay is turned ON.
The power window relay keeps ON for 30 seconds even when stopping the engine.
However, the power window relay is turned OFF when opening a front door.
When locking the door (activation of theft deterrent mode), the power window relay is
immediately turned OFF. 1.

17) Sleep Mode
If the driver door/passenger door/rear doors/tailgate lock switch is not changed for 6 seconds with all
driver door/passenger door/rear doors/tailgate closed, key removed, IGN1 and IGN2 OFF, the
vehicle enters into sleep mode for system power down.
If any of conditions in Step (1) is not satisfied, the System Wake-up mode is activated.
When output such as room lamp, key hole illumination, tail lamps and power window is activating or
all the doors keep closed for 30 seconds after door is unlocked for conditions in Step (1), the system
is in normal mode. Then, if there is no change within 6 seconds with all output conditions and ready
conditions released and all the doors closed, the sleep mode is activated.
When turning on the overhead room lamp switch, the overhead room lamps come on for 10 minutes
and go off, and the sleep mode is activated after 6 seconds.
When the coming home light OFF conditions are satisfied, the sleep mode is activated.
In this condition, when opening a door or inserting the ignition key into key hole, the sleep mode is
deactivated. 1.

19) DRL (Daytime Running Light) Control
When receiving the DRL activation signal, the tail lamps are turned ON when turning the ignition
switch to ON position, and the headlamps are turned ON when the engine speed is 300 rpm or
higher.
When turning ON the tail lamp switch during engine running, the headlamps are turned OFF.
The headlamps do not come ON when the engine speed is above 300 rpm with the tail lamp switch
ON.
The auto light sensor is not available in the vehicle with DRL system.
If there is no DRL activation signal, the light system operates in normal conditions. 1.

20) Fog Lamp Control
When pressing the rear fog lamp switch with IGN2 ON (headlamp ON condition), the rear fog lamps
are turned ON. When pressing the rear fog lamp switch again during the operation, the rear fog lamps
are turned OFF.
The rear fog lamps do not come ON when the IGN2 switch is turned to OFF position or the light
switch is OFF.
The rear fog lamps should not automatically come on again if they have been turned OFF by any
other way other than the switch. 1.
