BCW (Blind-spot Collision Warning)
Operating Conditions

To operate:
Press the BCW switch when the engine Start/Stop button is in the ON position.
The indicator on the BCW switch will illuminate.
To cancel:
Press the BCW switch again. The indicator on the switch will turn off. When the system is not in use, turn it off by pressing the switch.
Information
- If the engine Start/Stop button is turned off and then back on, the BCW system returns to its previous state.
- When the system is on, the warning light on the outside rearview mirror illuminates for 3 seconds.
The function is activated when:
1. The system is turned on.
2. The vehicle speed is approximately 30 km/h or higher.
3. An approaching vehicle is detected in the blind spot.

If a vehicle is detected within the system's detection zone, the warning light (amber) will illuminate on the outside rearview mirror.
Once the detected vehicle is no longer in the blind spot, the warning turns off depending on driving conditions.
Second-Stage Warning

The warning chime to alert the driver sounds when:
1. The radar sensor detects a vehicle in the blind spot (i.e., the warning light illuminates on the outside rearview mirror) (i.e., in the first warning stage) and
2. The turn signal indicator turns on (on the same side where the vehicle is detected).
When this warning is activated, the warning indicator on the outside rearview mirror illuminates and also flashes.
When the turn signal is turned off, the second stage warning (warning chime and flashing warning indicator on the outside rearview mirror) will be deactivated.
• The second stage warning may be deactivated.
