- When driving without 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-origi nal brake parts or suspension parts.
- When towing a trailer or other vehicle.
 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 marker s; 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.
- On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or
lines remaining after road repairs (The LDP syste m 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 exampl e, 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.

PRECAUTIONS FOR LANE DEPARTURE WARNING (LDW)
 LDW system is only a warning devic e to inform the driver of a potential unintended lane departure. It will not
steer the vehicle or prevent loss of c ontrol. 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 s peeds 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 marker s; 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 syst em 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 exampl e, 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-devel oped 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 unexpect ed system operation. In such conditions, driver needs
to correct the vehicle's direction with dr iver'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 approximat ely 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 c onditions (for example, tire wear, low tire pressure,
installation of spare tire, tire chains, non-standard wheels).
- When the vehicle is equipped with non-origi nal 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 marker s; 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.
