LANE DEPARTURE WARNING SYSTEM
Revision: 2006 January2006 M35/M45
LANE DEPARTURE WARNING SYSTEM PFP:28442
Precautions for Lane Departure Warning (LDW) systemNKS003VF
WAR NING :
Lane Departure Warning (LDW) is only a warning device to inform the driver of an unintended lane
departure. It 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 the vehicle at all times.
LDW system does not operate under the following conditions:
–At speeds below approx. 72 km/h (45 MPH).
–If it cannot detect lane markers.
LDW system may not function properly under the following conditions:
–On roads where a water puddle, dirt or snow is covering the lane markers.
–On roads where the lane markers are faded or are not painted clearly.
–On roads where the lane markers are painted yellow.
LDW system may not monitor the lane markers in certain road, weather or driving conditions.
–On roads where there are sharp curves.
–Where the traveling lane merges or separates.
–On roads where the discontinued lane markers are present, such as near tollgates, etc.
–On roads where there are not general lane markers.
–On roads where the lane width is too narrow.
–During bad weather (rain, fog, snow, etc.).
–When strong light (for example, at sunrise or sunset) is directly shining on the front of the vehicle.
–When entering or exiting a tunnel where sudden changes in brightness occur.
–When traveling close to the vehicle in front of you, which causes obstruction of the camera unit
range.
–When the vehicle's traveling direction does not align with the lane marker.
–When rain, snow or dirt adhere to the windshield in front of the camera unit.
Excessive noise interferes with warning system chime sound and the chime may not be heard.
CAUTION:
To keep the LDW system operating properly, be sure to observe the following:
Always keep the windshield clean. The sensing capability of the camera unit depends on the con-
dition of the windshield. See “Appearance and care” for cleaning instruction.
Never strike or damage the areas around the camera unit.
Never touch the camera lens.
Never attach a sticker (including transparent material) or install an accessory near the camera
unit.
Never place reflective materials, such as a white paper or mirrors on the instrument panel. Reflec-
tion of the sunlight may adversely affect the camera unit's lane marker detection capability.
System DescriptionNKS003VG
LDW SYSTEM OPERATION
The Lane Departure Warning (LDW) system warns the driver when the vehicle is traveling close to either
the left or the right of the traveling lane.
The system monitors lane markers of the traveling lane using the LDW camera unit. When the LDW cam-
era unit detects that the vehicle is traveling close to either the left or the right of the traveling lane, the
LDW indicator lamp flashes and a chime sounds to alert the driver.
NOTE:
When activating turn signal, LDW system does not give a warning to the lane marker on the turn signal
side.
The LDW system can be turned on or off by pushing the LDW switch. When the system is on, the LDW
system ON indicator illuminates.
The LDW system has an automatic mode and manual mode.

through grounds M16 and M70.
Action TestNKS003VH
LDW SYSTEM RUNNING TEST
WAR NING :
Be careful when performing road test.
Understand “Precautions” and “System Description” well before the road test. Refer to DI-78,
"Precautions for Lane Departure Warning (LDW) system" and DI-78, "System Description" .
Function Check
Check the LDW system operation according to the condition that the warning function works. Refer to DI-78,
"LDW SYSTEM OPERATION" .
PKIC0698E
Component Description
LDW camera unitDetects the lane marker by the built-in camera, gives judgement for the warning according to the
result of detection and signals from each unit, and transmits the operation signal to LDW chime and
LDW indicator lamp.
LDW switch
Selects ON/OFF of the system.
Indicates ON/OFF of the signal with LDW system ON indicator.
LDW chime Gives a warning chime according to the direction from LDW camera unit.
LDW indicator lampInstalled in combination meter, and indicates the system condition.
Blinks when LDW system is functioning to alert the driver.
Stays on when LDW system is malfunctioning.*
BCM Transmits turn indicator signal to LDW camera unit with CAN communication signal.
ABS actuator and electric unit
(control unit)Transmits vehicle speed signal to LDW camera unit with CAN communication signal.

OUTLINE
Adjust the camera aiming every time the LDW camera unit is removed or installed.
CAUTION:
Place the vehicle on the level ground when the camera aiming adjustment is operated.
Follow the CONSULT-II when adjusting the camera aiming. (Camera aiming adjustment cannot be
operated without CONSULT-II.)
PREPARATION
Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.
There is no-load in vehicle. Check if coolant, engine oil are filled up to correct level and fuel tank is full.
Shift the gear into “P” position and release the parking brake.
Clean the windshield.
NOTE:
Do not place anything reflective on the upper surface of instrument panel.
TARGET SETTING

“FW”.
CAUTION:
Make sure that “E” through “X” is equal to “F” through “X”.
8. Position the center of the right target to the point of “X”.
VEHICLE HEIGHT CHECK
Measure the wheel arch height. And calculate “Dh”.
NOTE:
“Dh” may be calculated as a minus value.
AIMING ADJUSTMENT
Operation Procedure
CAUTION:
Perform the adjustment under unloaded vehicle condition.
LDW indicator is turned off after the removal/installation, and blinks after replacement.

SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Start the engine, wait for at least 10 seconds, and touch “START
(NISSAN BASED VHCL)”.
