PRECAUTIONS FOR LANE DEPARTURE WARNING (LDW)

• LDW system is only a warning device to inform the driver of a potential 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 will not operate at speeds below approximately 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 markers; 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 contrasting objects, such as shadows, snow, water, wheel ruts, seams or

lines remaining after road repairs. (The LDW system 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 windshield 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 unit. (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 example, when the vehicle enters or exits a tunnel or

under a bridge.) 

PRECAUTIONS FOR 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-developed 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 unexpected system operation. In such conditions, driver needs
to correct the vehicle's direction with driver'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 approximately 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 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.
- When driving with a tire that is not within normal tire conditions (for example, tire wear, low tire pressure,

installation of spare tire, tire chains, non-standard wheels).

- When the vehicle is equipped with non-original brake parts or suspension parts.
• Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
• The functions of the LDP system (warning and brake control assist) may or may not operate properly under

the following conditions:

- On roads where there are multiple parallel lane markers; 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 discontinued lane markers are still detectable.
- On roads where there are sharp curves.

NORMAL OPERATING CONDITION

- On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or

lines remaining after road repairs (The LDP system 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 windshield 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 unit (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 example, when the vehicle enters or exits a tunnel or

under a bridge.)

• While the LDP system is operating, driver may hear a sound of brake operation. This is normal and indicates

that the LDP system is operating properly.
