i-ACTIVSENSE

The system is only designed to assist you in checking for vehicles at your rear when making a lane change. Due to certain limitations with the operation of this system, the Blind Spot Monitoring (BSM) warning light may not flash or it might be delayed even though a vehicle is in an adjacent driving lane. Always make it your responsibility as a driver to check the rear.

• The ignition is switched ON.

• The Blind Spot Monitoring (BSM) switch is pressed and the Blind Spot Monitoring (BSM) OFF indication/indicator light in the instrument cluster is turned off.

• The vehicle speed is about 10 km/h (6.3 mph) or faster.

The Blind Spot Monitoring (BSM) system will not operate under the following circumstances.

• The vehicle speed falls below about 10 km/h (6.3 mph) even though the Blind Spot Monitoring (BSM) OFF indicator light is turned off.

• The shift lever (manual transaxle)/selector lever (automatic transaxle) is shifted to reverse (R) and the vehicle is reversing.

In the following cases, the Blind Spot Monitoring (BSM) OFF indicator light turns on and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF indicator light remains illuminated, have the vehicle inspected at an Authorised Mazda Dealer as soon as possible.

• Some problem with the system including the Blind Spot Monitoring (BSM) warning lights is detected.

• A large deviation in the installation position of a radar sensor (rear) on the vehicle has occurred.

• There is a large accumulation of snow or ice on the rear bumper near a radar sensor (rear). Remove any snow, ice or mud on the rear bumper.

• Driving on snow-covered roads for long periods.

• The temperature near the radar sensors (rear) becomes extremely hot due to driving for long periods on slopes during the summer.

• The battery voltage has decreased.

The radar sensors may not detect all types of vehicles around your vehicle, especially the following types of vehicles:

• Motorcycles

• Vehicles with body shapes that radar may not reflect such as a flatbed trailer with no cargo.

• Vehicles with lower body height such as sports cars.

Under the following conditions, the radar sensors (rear) cannot detect target objects or it may be difficult to detect them.

• A vehicle is in the detection area at the rear in an adjacent driving lane but it does not approach. The Blind Spot Monitoring (BSM) system determines the condition based on radar detection data.

• A vehicle is travelling alongside your vehicle at nearly the same speed for an extended period of time.

• Vehicles approaching in the opposite direction.

• A vehicle in an adjacent driving lane is attempting to pass your vehicle.

• A vehicle is in an adjacent lane on a road with extremely wide driving lanes. The detection area of the radar sensors (rear) is set at the road width of expressways.

In the following cases, the activation of the Blind Spot Monitoring (BSM) warning lights and the warning beep may not occur or they may be delayed.

• A vehicle makes a lane change from a driving lane two lanes over to an adjacent lane.

• Driving on steep slopes.

• Crossing the summit of a hill or mountain pass.

• The turning radius is small (making a sharp curve, turning at intersections).

• When there is a difference in the height between your driving lane and the adjacent lane.

• Directly after pressing the Blind Spot Monitoring (BSM) switch and the system becomes operable.

If the road width is extremely narrow, vehicles two lanes over may be detected. The detection area of the radar sensors (rear) is set according to the road width of expressways.

Although the system may detect objects on the road side such as parked vehicles or guardrails and operate the warning light/beep, it does not indicate a malfunction.

A Blind Spot Monitoring (BSM) warning light may flash or the warning beep may be activated several times when making a turn at a city intersection.

Turn off the Blind Spot Monitoring (BSM) system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radar's radio waves will be blocked causing the system to not operate normally.

In the following cases, it may be difficult to view the illumination/flashing of the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors.

• Snow or ice is adhering to the door mirrors.

• The front door glass is fogged or covered in snow, frost or dirt.

The system switches to the Rear Cross Traffic Alert function when the shift lever (manual transaxle) or the selector lever (automatic transaxle) is shifted to the reverse (R) position.
