Alternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.
1. SYSTEM DESCRIPTION
1) Overview
The charge system is designed to supply electrical energy to the vehicle while driving, and supplies a
constant direct current voltage by converting mechanical rotational movement to electrical energy.
The voltage regulator on the back of the alternator controls the generated voltage in all rotating ranges and
adjusts the system voltage according to the electric load and ambient temperature change.
2) System Layout (Locations)
Battery
It converts the chemical energy to the
electrical energy and supplies power to the
corresponding electric units when starting
the engine.

1. CRUISE CONTROL SWITCH
The cruise control is an automatic speed control system that maintains a desired driving speed without
using the accelerator pedal.
The vehicle speed must be greater than 36 km/h to engage the cruise control. This feature is
especially useful for motorway driving.
The cruise control system is a supplementary system, which helps the driver to drive the vehicle at
a desired speed without using the accelerator pedal under the traffic condition where the vehicle-to-
vehicle distance meets the legal requirement.

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;
Keep the main cruise control switch in the neutral position when not using the cruise control.When the brake pedal is depressed.
When the cruising speed is downed less than 38 km/h.
When the OFF switch is operated by pulling the cruise control lever (Type A) or by pushing the ON-
OFF switch of the cruise control lever (Type B).
When ESP is activated.
When applying the parking brake when driving.
When using the clutch in order to shift (M/T only).
And the cruise control system can be operated again in driving state. 1.

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 -
