System Description
Blind-Spot Collision Warning (BCW)
The Blind-Spot Collision Warning (BCW) system uses radar sensors in the rear bumper to monitor and warn the driver of an approaching vehicle in the driver's blind spot area.
1) Blind-Spot Area

The blind spot detection range varies relative to vehicle speed.
Note that if your vehicle is traveling much faster than the vehicles around you, the warning will not occur.
2) Closing at high speed

The Lane Change Assist feature will alert you when it detects a vehicle is approaching in an adjacent lane at a high rate of speed. If the driver activates the turn signal when the system detects an oncoming vehicle, the system sounds an audible alert.
