SYSTEM
• Moving Object Detection braking will not operate or
will stop operating and only a warning chime will sound
under the following conditions:
- When driving with a tire that is not within normal tire conditions (pressure, wear, chain, spare, etc.)
- When the vehicle is equipped with non-original brake parts or suspension parts.
• Do not use the MOD system when towing a trailer.
• Excessive noise such as the audio system will inte rfere with the chime sound, and it may not be heard.

Precautions for Moving Objects DetectionINFOID:0000000009464892
REAR VIEW CAMERA HANDLING
• The rear view camera which is located on the back
of the trunk performs the Moving Object Detection sys-
tem.
• Always keep the rear view camera lens clean.
• Do not attach a sticker (including transparent material ), install an accessory or paint work over the camera
lens.
• Do not strike or scratch the lens causing physical damage to the camera or the surrounding area.
MOVING OBJECT DETECTION
• The Moving Object Detection system is not a repl acement for proper driving procedure and is not designed
to prevent contact with vehicles or objects. When backing up, always look in the direction driver will move to
ensure it is safe to proceed. Never rely solely on the Moving Object Detection system.
• Using the Moving Object Detection system under some road or weather conditions could lead to improper
system operation. Always rely on driver's own steering and braking operation to avoid accidents.
• The Moving Object Detection system may not provide a warning for vehicles that pass through the detection
zone quickly.
• Do not use the Moving Object Detection system when towing a trailer.
• Excessive noise (e.g., audio system volume, open v ehicle window) will interfere with the chime sound, and it
may not be heard.
• The rear view camera may not be able to detect and activate Moving Object Detection when certain objects are present such as:
- Pedestrians, bicycles, animals.
- A vehicle passing at a speed greater than approximately 15 MPH (24km/h).
• Severe weather or road spray conditions may reduce the ability of the radar to detect other vehicles.
• Do not use the MOD system under the following condi tions because the system may not function properly:
- When driving with a tire that is not within normal tire condition (example: tire wear, low pressure, spare tire, chain, non-standard wheels).
- When the vehicle is equipped with non-original brake parts or suspension parts.

COMPONENT PARTS
The mass air flow sensor is placed in the stream of intake air. It
measures the intake flow rate by measuring a part of the entire
intake flow. The MAF sensor controls the temperature of the heater
in sensing element to a certain amount. The temperature distribution
around the heater changes according to the increase in intake air
volume. The change is detected by a thermistor and the air volume
data is sent to ECM by the MAF sensor.
INTAKE AIR TEMPERATURE SENSOR
The intake air temperature sensor is built-into mass air flow sensor. The sensor detects intake air temperature
and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor wh ich is sensitive to the change in temperature.
*: These data are reference values on the diagnosis tool.
Manifold Absolute Pressure SensorINFOID:0000000009462062
The manifold absolute pressure (MAP) sensor is placed at intake
manifold collector. It detects intake manifold pressure and sends the
voltage signal to the ECM.
The sensor uses a silicon diaphragm which is sensitive to the
change in pressure. As the pressure increases, the voltage rises.
NOTE:
The sensor is equipped, but used for trouble diagnosis only.
Engine Coolant Te mperature SensorINFOID:0000000009462063
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The elec trical resistance of the ther-
mistor decreases as temperature increases.

The mass air flow sensor (1) is plac
ed in the stream of intake air. It
measures the intake flow rate by measuring a part of the entire
intake flow. The mass air flow sens or controls the temperature of the
hot wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.
INTAKE AIR TEMPERATURE SENSOR
The intake air temperature sensor is built-into mass air flow sensor. The sensor detects intake air temperature
and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical
resistance of the thermistor decreases in response to the temperature rise.
*: These data are reference values and are measured between ECM terminals.
Oil Pressure Warning LampINFOID:0000000009462506
Oil pressure warning lamp is located on the combination meter.
It indicates the low pressure of the engine oil and the malfunction of
the engine oil pressure system.
Combination meter turns the oil pressure warning lamp ON/OFF
according to the oil pressure warning lamp signal received from
ECM via CAN communication.
For details, refer to EC-583, "ENGINE PROTECTION CONTROL AT
LOW ENGINE OIL PRESSURE : System Description".
Power Valve Actuator 1 and 2INFOID:0000000009462507
The power valves are used to control the suction pa ssage of the variable induction air control system. They
are set in the fully closed or fully opened position by t he power valve actuators operated by the vacuum stored
in the vacuum tank. The vacuum to power valve actuat ors is controlled by the VIAS control solenoid valves.
