DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
CONSULT Function (AVM)INFOID:0000000009951646
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and no-start condition.

Work Procedure (Target Setting)INFOID:0000000009464827
CAUTION:
• Perform this operation in a horizontal position wh ere there is a clear view for 3 m (9.84 ft) backward
and 4 m (13.12 ft) wide.
• Place the target in a well-lig hted location. (Poor lighting may make it hard to adjust.)
• The target may not be detected when it shines by the reflected light of the sun or lighting.
• The target may not be detected when there is the same pattern of black and white as the target when
the pattern is within 0.5 m (1.64 ft) from either si de and upward/downward position from the target. (It
is desirable that the vehicle is pos itioned on a single-color floor.)
1.TARGET SETTING
1. Mark points “A”, “B”, “C” and “D” at the center of the lateral sur- face of each wheel.
NOTE:
Hang a string with a cone from the fender so as to pass through
the center of wheel, and then mark a point at the center of the
lateral surface of the wheel.
2. Draw line “LH” passing through points “A” and “B” on the left side of vehicle.
NOTE:
Approximately 2.2 m (7.22 ft) or more at the rear from the rear
axle.
3. Mark point “E” on the line “LH” at the positions 2125 mm (83.66
in) from point “B”.
4. Draw line “RH” passing through points “C” and “D” on the right side of vehicle in the same way as step 2.
5. Mark point “F” on the line “RH” at the positions 2125 mm (83.66 in) from point “D”.
6. Draw line “RW” passing through the points “E” and “F” on the rear of the vehicle. NOTE:
Approximately 1.8 m (5.91 ft) or more at bot h left and right sides from vehicle center.
7. Mark point “C
t” at the center of point “E” and “F” on the line “RW”.
CAUTION:
Make sure that “E” to “C
t” is equal to “F” to “Ct”.
8. Mark point "Lt" and "Rt" on the line "RW" at t he positions 1500 mm (59.06 in) from point "Ct".
9. Position the center of the ta rget mark to point of “Ct”.
Side distance (S
d): “B”–“E” (“D”–“F”) : 2125 mm (83.66 in)
Left distance (L
d): “Ct”–“Lt” : 1500 mm (59.06 in)

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.

HANDLING PRECAUTION

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.
