When Driving

Your vehicle is equipped with radar sensors (rear). The following systems also use the radar
sensors (rear).
Blind Spot Monitoring system (BSM)

Rear Cross Traffic Alert (RCTA)

The radar sensors (rear) function by detecting the radio waves reflected off a vehicle
approaching from the rear or an obstruction sent from the radar sensor.
Radar sensors (rear)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Always keep the surface of the rear bumper near the radar sensors (rear) clean so that the
radar sensors (rear) operate normally. Also, do not apply items such as stickers.
Refer to Exterior Care on page 6-59.
CAUTION
If the rear bumper receives a severe impact, the system may no longer operate normally.
Stop the system immediately and have the vehicle inspected at an Authorized Mazda
Dealer.
