LANE DEPARTURE WARNING SYSTEM PFP:28442
Precautions for Lane Departure Warning (LDW) systemNKS003VF
WARNING:
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.
