PRECAUTIONS FOR BLIND SPOT WARNING (BSW)
• The Blind Spot Warning system is not a replacem
ent for proper driving procedure and are not designed to
prevent contact with vehicles or objects. When c hanging lanes, always use the side and rear mirrors and
turn and look in the direction driver will move to ensure it is safe to change lanes. Never rely solely on the
Blind Spot Warning system.
• The Blind Spot Warning system may not provide a warn ing for vehicles that pass through the detection zone
quickly.
• Do not use the Blind Spot Warning system when towing a trailer.
• Excessive noise (e.g., audio system volume, open v ehicle window) will interfere with the chime sound, and it
may not be heard.
• The rear view camera may not be able to detect and activate Blind Spot Warning when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- Vehicles remaining in the detection zone when driver accelerates from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- Another vehicle which overtakes this vehicle rapidly.
• Severe weather or road spray conditions may reduce the abi lity of the rear view camera to detect other vehi-
cles.
• The rear view camera detection zone is designed based on a standard lane width. When driving in a wider
lane, the rear view camera may not detect vehicles in an adjacent lane. When driving in a narrow lane, the
rear view camera may detect vehicles driving two lanes away.
• The rear view camera is designed to ignore most stationary objects, however objects such as guardrails,
walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition.
PRECAUTIONS FOR BLIND SPOT WARNING
• Do not use the Blind Spot Warning system under the following conditions because the system may not func-
tion properly:
- During bad weather (e.g., 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 (e.g., 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.
• The rear view camera may not detect lane markers in the following situations and the Blind Spot Warning
system may not operate properly:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; nonstandard lane markers; lane markers covered with water, dirt, snow, etc.
- On roads where 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.
- On roads where the traveling lane merges or separates.
- When the vehicle traveling direction does not align with the lane markers.
- When rain, snow or dirt adheres to the lens of a the rear view camera unit.
- When a sudden change in brightness occurs. (e.g., when the vehicle enters or exits a tunnel or under a
bridge.)
- When steering quickly.
- When the hazard warning flashers are operated.
- When driving on a curve at a high speed.
