LANE DEPARTURE WARNING SYSTEM 

Precaution for Lane Departure Warning (LDW) system

INFOID:0000000001328492

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 condi-

tion 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. Reflection

of the sunlight may adversely affect the camera unit's lane marker detection capability.

System Description

INFOID: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 traveling 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 the 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 ignition switch is turned to the ON position. 
- LDW system ON indicator located on the LDW switch 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 ignition switch is turned to the ON position.

DI-70

< SERVICE INFORMATION >

LANE DEPARTURE WARNING SYSTEM

- The LDW switch must be pushed to turn on the system.

To the change modes

- Push and hold LDW switch for more than 4 seconds, when LDW system ON indicator is off.
- Then LDW chime sounds and blinking of LDW system ON indicator informs that the mode change is com-

pleted.

• Temporary disabled status at high temperature
- If the vehicle is parked in direct sunlight under high temperature conditions [approximately over 104

°

F

(40

°

C)] and then started, the LDW system may sound a chime and cancel automatically. Then LDW system

ON indicator will blink.

- When the interior temperature is reduced, the system will resume to operate automatically and the LDW sys-

tem ON indicator illuminates.
