LANE CAMERA UNIT HANDLING
To keep the proper operation of the LDW/LDP systems and prevent a system malfunction, be sure to observe
the following:
Always keep the windshield clean.
Do not attach a sticker (including transparent materi al) or install an accessory near the lane camera unit.
Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of
sunlight may adversely affect the lane camera unit capability of detecting the lane markers.
Do not strike or damage the areas around the lane camera unit.
Do not touch the camera lens.
Do not remove the screw located on the lane 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.
LDW system will not operate at speeds below approximat ely 70 km/h (45 MPH) or if it cannot detect lane
markers.
Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
LDW system may not function 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 traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection
range.
- When rain, snow or dirt adheres to the wi ndshield in front of the lane camera unit.
- When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
- When strong light enters the lane camera uni t. (For example, the light directly shines on the front of the vehi-
cle at sunrise or sunset.)
- When a sudden change in brightness occurs. (For exampl e, when the vehicle enters or exits a tunnel or
under a bridge.)
LANE DEPARTURE PREVENTION (LDP)
LDP system will not steer the vehicle or prevent loss of control. It is the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the traveling lane, and be in control of vehicle at all times.
LDP system is primarily intended for use on well-dev eloped freeways or highways. It may not detect the lane
markers in certain roads, weather or driving conditions.
Using the LDP system under some conditions of road, lane marker or weather, or when driver change lanes
without using the turn signal could lead to an unexpect ed system operation. In such conditions, driver needs
to correct the vehicle's direction with dr iver's steering operation to avoid accidents.
When the LDP system is operating, avoid excessive or sudden steering maneuvers. Otherwise, driver could
lose control of the vehicle.
The LDP system will not operate at speeds below approxim ately 70 km/h (45 MPH) or if it cannot detect lane
markers.
The LDP system may not function properly under the following conditions, and do not use the LDP system:
- During bad weather (rain, fog, snow, wind, etc.).
- When driving on slippery roads, such as on ice or snow, etc.
- When driving off-road such as on sand or rock, 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.

DescriptionINFOID:0000000006223734
Always adjust the camera aiming after removing
and installing or replacing the lane camera unit.
CAUTION:
Place the vehicle on level ground when th e camera aiming adjustment is operated.
Follow the CONSULT-III when performing the came ra aiming. (Camera aiming adjustment cannot be
operated without CONSULT-III.)
Work Procedure (Preparation)INFOID:0000000006223735
1.PERFORM SELF-DIAGNOSIS
Perform self-diagnosis of ADAS control unit and lane camera unit.
Is any DTC detected?
Except “C1B01”>>Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to
DAS-310, "
DTC Index" (ICC/ADAS) or DAS-316, "DTC Index" (LANE CAMERA).
“C1B01” or no DTC>>GO TO 2.
2.PREPARATION BEFORE CAMERA AIMING ADJUSTMENT
1. Perform pre-inspection for diagnosis. Refer to DAS-335, "
Inspection Procedure".
2. Adjust the tire pressure to the specified pressure value.
3. Maintain no-load in vehicle.
4. Check if coolant and engine oil are filled up to correct level and fuel tank is full.
5. Shift the selector lever to “P” position and release the parking brake.
6. Clean the windshield.
7. Completely clear off the instrument panel.
>> GO TO 3.
3. PREPARATION OF AIMING ADJUSTMENT JIG
Prepare the aiming adjustment jig according to the following procedure and the figure.
1. Print out the target mark attached in this service manual. Refer to DAS-343, "
Work Procedure (Target
Mark Sample)".
2. Stick a printed target mark on the board with a scotch tape or a piece of double-sided tape.
