PRECAUTIONS FOR BLIND SPOT WARNING (BSW)

• The BSW system is not a replacement for proper driving procedure and are not designed to prevent contact

with vehicles or objects. When changing 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 BSW system.

• The BSW system may not provide a warning for vehicles that pass through the detection zone quickly.
• Do not use the BSW system when towing a trailer because the system may not function properly.
• Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it

may not be heard.

• The side radar may not be able to detect and activate BSW 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 accelerate from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- A vehicle which vehicle overtakes rapidly.
• Severe weather or road spray conditions may reduce the ability of the side radar to detect other vehicles.
• The side radar detection zone is designed based on a standard lane width. When driving in a wider lane, the

side radar may not detect vehicles in an adjacent lane. When driving in a narrow lane, the side radar may
detect vehicles driving two lanes away.

• The side radar are 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.
