FORWARD COLLISION WARNING (FCW)
 FCW system is intended to warn the driver before a collis ion but will not avoid a collision. It is the drive's
responsibility to stay alert, drive safely and be in control of the vehicle at all times.
 As there is a performance limit, the FCW system ma y not provide a warning in certain conditions.
 The FCW system will not detect the following objects.
- Pedestrians, animals, or obstacles in the roadway.
- Oncoming vehicles in the same lane
 FCW system will not detect under the following conditions.
- When the sensor gets dirty, it is impossibl e to detect the distance from the vehicle ahead.
- When driving into a strong light (i.e. sunlight)
 The sensor generally detects signals returned from t he reflectors on a vehicle ahead. Therefore, the FCW
system may not warn properly under the following conditions:
- When the reflectors of the vehicle ahead are positioned high or close to each other (including a small vehicle such as motorcycles).
- When the sensor gets dirty or it is impossible to detect the distance to the vehicle ahead.
- When the reflectors on the vehicle ahead is missing, damaged or covered.
- When the reflector of the vehicle ahead is covered with dirt, snow or road spray.
- When visibility is low (such as rain, fog, snow, etc.).
- When snow or road spray from traveling vehicles are splashed.
- When dense exhaust or other smoke (black smoke) from vehicles reduces the visibility of the sensor.
- When excessively heavy baggage is loaded in the rear seat or the luggage room of own vehicle.
- When abruptly accelerating or decelerating.
- On steep downhill or roads with sharp curves.
- When there is a highly reflective object near the vehicle ahead.
i.e.) very close to other vehicle, signboard, etc.
- When own vehicle are towing a trailer.
 Depending on certain road conditions (curved, beginning of a curve), vehicle conditions (steering position,
vehicle position), or preceding vehicle's conditions (pos ition in lane, etc.), the FCW system may not function
properly. The FCW system may detect highly reflective obj ects such as reflectors, signs, white markers, and
other stationary objects on the road or near the traveling lane, and provide unnecessary warning.
 The FCW system may not function in offset conditions.
 The FCW system may not function when the dist ance to the vehicle ahead is extremely close.
 The FCW system is designed to automat ically check the sensor's functionality. If the sensor is covered with
ice, a transparent or translucent pl astic bag, etc., the system may not detect them. In these instances the
FCW system may not be able to warn properly. Be sure to check and clean the sensor regularly.
 Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
 A sudden appearance of the vehicle in front (i.e.: w hen a vehicle abruptly cuts in) may not be detected and
the system may not warn soon enough.
 The FCW system will be canceled automatically with a chime sound and the IBA OFF indicator light will illu-
minate under the following conditions:
- When the sensor window is dirty
- When the FCW system malfunctions

Precautions for Lane Departure Wa
rning/Lane Departure PreventionINFOID:0000000006223714
LANE CAMERA UNIT HANDLING
To keep the proper operation of the LDW/LDP systems and prevent a system malfunction, be sure to observe
the following:
 Always keep the windshield clean.
 Do not attach a sticker (including transparent materi al) or install an accessory near the lane camera unit.
 Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of
sunlight may adversely affect the lane camera unit capability of detecting the lane markers.
 Do not strike or damage the areas around the lane camera unit.
 Do not touch the camera lens.
 Do not remove the screw located on the lane camera unit.
LANE DEPARTURE WARNING (LDW)
 LDW system is only a warning device to inform the dr iver of a potential unintended lane departure. It will not
steer the vehicle or prevent loss of cont rol. 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 approximat ely 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 c ontrasting 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 wi ndshield 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 uni t. (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.)
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-dev eloped 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 approxim ately 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 off-road such as on sand or rock, 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 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.
