PRECAUTIONS FOR BLIND SPOT WARNING (BSW)
• The Blind Spot Warning system is not a replacem
ent for proper driving procedure and are not designed to
prevent contact with vehicles or objects. When c hanging lanes, always use the side and rear mirrors and
turn and look in the direction driver will move to ensure it is safe to change lanes. Never rely solely on the
Blind Spot Warning system.
• The Blind Spot Warning system may not provide a warn ing for vehicles that pass through the detection zone
quickly.
• Do not use the Blind Spot Warning 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 Blind Spot Warning when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- Vehicles remaining in the detection zone when driver accelerates from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- Another vehicle which overtakes this vehicle rapidly.
• Severe weather or road spray conditions may reduce the abi lity of the rear view camera to detect other vehi-
cles.
• The rear view camera detection zone is designed based on a standard lane width. When driving in a wider
lane, the rear view camera may not detect vehicles in an adjacent lane. When driving in a narrow lane, the
rear view camera may detect vehicles driving two lanes away.
• The rear view camera is designed to ignore most stationary objects, however objects such as guardrails,
walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition.
PRECAUTIONS FOR BLIND SPOT WARNING
• Do not use the Blind Spot Warning system under the following conditions because the system may not func-
tion properly:
- During bad weather (e.g., rain, fog, snow, wind, etc.)
- When driving on slippery roads, such as on ice or snow, etc.
- When driving on winding or uneven roads.
- When there is a lane closure due to road repairs.
- When driving in a makeshift lane.
- When driving on roads where the lane width is too narrow.
- When driving with a tire that is not within normal tire c onditions (e.g., tire wear, low tire pressure, installation
of spare tire, tire chains, non-standard wheels).
- When the vehicle is equipped with non-original brake parts or suspension parts.
• The rear view camera may not detect lane markers in the following situations and the Blind Spot Warning
system may not operate properly:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; nonstandard lane markers; lane markers covered with water, dirt, snow, etc.
- On roads where discontinued lane markers are still detectable.
- On roads where there are sharp curves.
- On roads where there are sharply c ontrasting objects, such as shadows, snow, water, wheel ruts, seams or
lines remaining after road repairs.
- On roads where the traveling lane merges or separates.
- When the vehicle traveling direction does not align with the lane markers.
- When rain, snow or dirt adheres to the lens of a the rear view camera unit.
- When a sudden change in brightness occurs. (e.g., when the vehicle enters or exits a tunnel or under a
bridge.)
- When steering quickly.
- When the hazard warning flashers are operated.
- When driving on a curve at a high speed.

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.

ECMINFOID:0000000009462054
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.
Accelerator Pedal Position SensorINFOID:0000000009462055
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelera-
tor position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometers which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of
the accelerator pedal and feed the voltage signals to the ECM. The
ECM judges the current opening angle of the accelerator pedal from
these signals and controls the throttle control motor based on these
signals.
Idle position of the accelerato r pedal is determined by the ECM
receiving the signal from the acce lerator pedal position sensor. The
ECM uses this signal for the engine operation such as fuel cut.
Electric Throttle Control ActuatorINFOID:0000000009462056
Electric throttle control actuator cons ists of throttle body, throttle valve, throttle control motor and throttle posi-
tion sensor.

The ECM activates the fuel pump for 1 second after the ignition
switch is turned ON to improve engine start ability. If the ECM
receives a engine speed signal from the camshaft position sensor
(PHASE), it knows that the engine is rotating, and causes the pump
to operate. If the engine speed signal is not received when the igni-
tion switch is ON, the engine stalls. The ECM stops pump operation
and prevents battery discharging, thereby improving safety. The
ECM does not directly drive the fuel pump. It sends the control signal
to the fuel pump control module, which in turn controls the fuel
pump.
FUEL LEVEL SENSOR
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and tr ansmits a signal to the combination meter. The combina-
tion meter sends the fuel level sensor signal to the ECM via the CAN communication line.
It consists of two parts, one is mechanical float and the ot her is variable resistor. Fuel level sensor output volt-
age changes depending on the movement of the fuel mechanical float.
Fuel Tank Temperature SensorINFOID:0000000009462060
The fuel tank temperature sensor is used to detect the fuel tempera-
ture inside the fuel tank. The sensor modifies a voltage signal from
the ECM. The modified signal returns to the ECM as the fuel temper-
ature input. The sensor uses a ther mistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.

SYSTEM
When starting the engine by cold start, ECM judges the
locked/unlocked state when ignition switch is turned
ON. When judged as locked state (fixed at the intermedi ate phase), the intake valve timing intermediate lock
control solenoid valve is activated. Since oil pre ssure does not act on the lock key even when the engine is
started, the cam phase is fixed at the intermediate phas e and the intake valve timing control is not performed.
When the engine stops without locking the cam phase at the intermediate phase due to an engine stall and the
state is not judged as locked, the intake valve timing intermediate lock control solenoid valve and the intake
valve timing control solenoid valve are activated and the cam phase shifts to the advanced position to be
locked at the intermediate phase. Even when not locked in the intermediate lock phase due to no oil pressure
or low oil pressure, a ratchet structure of the camshaft sprocket (INT) rotor allows the conversion to the inter-
mediate phase in stages by engine vibration.
When engine coolant temperature is more than 60 °C, the intake valve timing is controlled by deactivating the
intake valve timing intermediate lock control so lenoid valve and releasing the intermediate phase lock.
When the engine is started after warming up, ECM releas es the intermediate phase lock immediately after the
engine start and controls the intake valve timing.
