3. OPERATION
1) Setting a Desired Speed
To operate the cruise control, accelerate to the desired speed, which must be more than 36
km/h and less than 150 km/h.
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.
Now, the vehicle is cruised by this system with the set speed. You don't need to use the
accelerator pedal.
Refer to the following pages for details of operation. 1.
2.
3.
4.
Never use the cruise control system until you get used to it.
Improper use or not fully aware of this function could result in collision and/or personal injuries.

12-8
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 leve 1.
2.
(2) When the cruise control system is not running
To increase the speed with the cruise control system while the system is not running, follow the
procedures below.
Accelerate using the accelerator pedal over 36 km/h.
Push up the ACCEL switch of the cruise control lever and hold it. And then release the
accelerator pedal slowly.
When the desired speed is reached, release the lever. 1.
2.
3.
(3) Tap-up while the cruise control system is running
To increase the vehicle speed in stages while the cruise control system is running, follow the
procedures below.
Push up the ACCEL 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-up switching. When you operate a tap-
up switching, the vehicle is accelerated for 1.3 km/h over the previous set speed.
If you want to accelerate for 13 km/h, operate the tap-up switching ten times without
accelerating with the cruise control system. 1.
2.

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.
2.
3.
(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.
2.

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.

12-118511-23
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 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.
2.
3.
4.
Keep the main cruise control switch in the neutral position when not using the cruise control.

12-12
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.
2.
3.
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.

1. SYSTEM DESCRIPTION
1) Overview
The EGR (Electric-Exhaust Gas Recirculation) valve reduces the NOx emission level by
recirculating some of the exhaust gas to the intake system.
To meet Euro-V regulation, the capacity and response rate of E-EGR valve in D20DTR engine
have been greatly improved. The EGR cooler with high capacity reduces the Nox, and the bypass
valve reduces the CO and HC due to EGR gas before warming up.
Also, the engine ECU adjusts the E-EGR opening by using the air mass signal through HFM
sensor. If the exhaust gas gets into the intake manifold when the EGR valve is open, the amount
of fresh air through HFM sensor should be decresed.
Benefits of E-EGR valve ▶
Improved accuracy and response through electric control
Feedback function (Potentiometer)
Preventing chattering of EGR valve and improved durability
Self-cleaning function -

EGR pipe
Transports the exhaust gas from the EGR
cooler and EGR bypass valve to the intake
duct.E-EGR valve
Receives the electric signal from the ECU to
control the valve.
E-EGR cooler and bypass valve
The cooler lowers the high temperature of the
exhaust gas and the bypass valve directly
supplies the exhaust gas to the intake duct
without passing through the EGR cooler to
reduce the emission of exhaust gas before
warming up the engine.HFM sensor
Used as a main map value to control the EGR.
The coolant temperature, engine rpm, engine
load, intake air temperature (HFM: decreased
at 60˚C or more), atmospheric pressure
(atmospheric pressure sensor: altitude
compensation) are used as auxiliary map
values.
