LANE DEPARTURE WARNING SYSTEM
Precaution for Lane Depa rture Warning (LDW) systemINFOID:0000000001328492
WARNING:
Lane Departure Warning (LDW) is only a warning d evice 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 u nder the following conditions:
- At speeds below approx. 72 km/h (45 MPH).
- If it cannot detect lane markers.
 LDW system may not function proper ly 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 marker s 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 sunse t) is directly shining on the front of the vehicle.
- When entering or exiting a tunnel wher e 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 ch ime sound and the chime may not be heard.
CAUTION:
To keep the LDW system operating proper ly, be sure to observe the following:
 Always keep the windshield clean. The sensing capability of the camera unit depends on the condi-
tion of the windshield. See “Appearan ce 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 mate rial) or install an accessory near the camera unit.
 Never place reflective materials, such as a white pape r or mirrors on the instrument panel. Reflection
of the sunlight may adversely affect the camera unit's lane marker detection capability.
System DescriptionINFOID:0000000001328493
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 camera
unit detects that the vehicle is traveli ng close to either the left or the right of the traveling lane, the LDW indi-
cator 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 t he LDW switch. When the system is on, the LDW sys-
tem ON indicator illuminates.
 The LDW system has an automatic mode and manual mode.
In the automatic mode
- LDW system automatically turns on, when the i gnition switch is turned to the ON position.
- LDW system ON indicator located on the LDW swit ch illuminates, indicating that the system is on.
- To cancel LDW system, push the LDW switch to turn off LDW system ON indicator.
- To turn on the system, push LDW switch again.
In the manual mode- LDW system is still off when the igniti on switch is turned to the ON position.
