Work Procedure (Target Setting)INFOID:0000000009464667
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)
Right distance (R

FAIL-SAFE CONTROL BY DTC
If a malfunction occurs in the rear view camera, ITS control unit cancels control, and turns ON the lane depar-
ture warning lamp in the combination meter.
BSW/LDW TEMPORARY DISABLED STATUS
Under the following condition, the BSW and/or LDW system is turned off temporarily, the BSW light (white)
and /or LDW light (white) will blink, and either of the following messages will appear in the vehicle information
display:
• ”trunk is open”
• ”washer fluid is low”
When the above condition no longer exists, the BSW and /or LDW system will resume automatically.

HANDLING PRECAUTION
HANDLING PRECAUTION
Precautions for Lane Departure WarningINFOID:0000000009464727
REAR VIEW CAMERA HANDLING
The rear camera unit “1” for the LDW/BSW syst
ems is located above the rear license plate.
To keep the proper operation of the LDW systems and pr event a system malfunction, be sure to observe the
following:
• Always keep the camera lens clean. Be careful not to damage the nozzle of the automatic washer and
blower.
• Do not attach ”license plate accessories” that reflect light.
• Do not strike or damage the areas around the camera unit.
LANE DEPARTURE WARNING (LDW)
• LDW system is only a warning device to inform the dr iver of a potential unintended lane departure. It will not
steer the vehicle or prevent loss of cont rol. It is the driver’s responsibility to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in control of the vehicle at all times.
• The camera unit may not detect properly under the following conditions:
- When towing a trailer.
- When strong light enters the camera unit. (For exampl e, direct sunlight or headlight from the rear.)
- When ambient light changes instantly. (For example, when the vehicle enters or exits a tunnel or passes
under a bridge.)
• Automatic washer and blower may not be able to secure detection capability when excessive dirt adheres on the camera lens.
• Excessive noise (e.g. audio system volume, open vehi cle window) will interfere with the chime sound, and it
may not be heard.
• The camera unit may not be able to detect properly under the following conditions:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt or snow,
etc.
- On roads where the 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. (The LDW syst em could detect these items as lane markers.)
- On roads where the traveling lane merges or separates.
- When the vehicle's traveling direction does not align with the lane marker.
- When the road surface is very dark due to scarce ambient light or impaired tail lamp.
• When driving on a curved road, warning will be late on the outside of the curve due to the nature of the sys-
tem.
