i-ACTIVSENSE

The BSM will operate when all of the following conditions are met:

• The ignition is switched ON.

• The BSM OFF indicator light in the instrument cluster is turned off.

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

The BSM will not operate under the following circumstances.

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

• The selector lever is shifted to R position and the vehicle is reversing.

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

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

• Some problem with the system including the BSM warning indicator 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.

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 BSM determines the condition based on radar detection data.

• A vehicle is traveling 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 case, the flashing of the BSM warning indicator light, and the activation of the warning sound and the warning screen indicator display may not occur or they may be delayed.

• A vehicle makes a lane change from a driving lane 2 lanes over to an adjacent lane.

• Driving on steep slopes.

• Crossing the summit of a hill or mountain pass.

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

• Directly after the BSM system becomes operable by changing the setting.

If the road width is extremely narrow, vehicles 2 lanes over may be detected. The detection area of the radar sensors (rear) is set according to the road width of expressways.

The BSM warning indicator light may turn on and the vehicle detection screen may be displayed in the display in reaction to stationary objects (guardrails, tunnels, sidewalls, and parked vehicles) on the road or the roadside.

A BSM warning indicator light may flash or the warning beep and the warning screen indicator display may be activated several times when making a turn at a city intersection.

Turn off the BSM 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 BSM warning indicator 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 radar sensors (rear) of the BSM may be regulated under the radio wave related laws of the country where the vehicle is driven. The sensors in this system are approved for use in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a BSM is driven in a country other than the U.S.A., Canada, or Mexico, the system has to be turned off using the BSM OFF switch.

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

Refer to Rear Cross Traffic Alert (RCTA) (Search).

The SCBS system will operate under the following conditions.

• The engine is running.

• The Smart Brake Support/Smart City Brake Support (SBS/SCBS) system warning indication (amber) does not illuminate.

• (Rear-end collision warning)

  The vehicle speed is about 4 to 80 km/h (2 to 50 mph).

• (Brake control (Smart City Brake Support (SCBS) brake))

  The vehicle speed is about 4 to 30 km/h (2 to 18 mph).

• The SCBS system is not turned off.

Under the following conditions, the SCBS system may not operate normally:

• The SCBS system will not operate if the driver is deliberately performing driving operations (accelerator pedal and steering wheel).

• If there is the possibility of partial contact with a vehicle ahead.

• The vehicle is driven on a slippery road surface such as wet roads or icy or snow-bound roads.

• The braking performance is adversely affected due to cold temperatures or wet brakes.

• The vehicle is driven at the same speed as the vehicle ahead.

• The accelerator pedal is depressed.

• The brake pedal is depressed.

• The steering wheel is being operated.

• The selector lever is being operated.

In the following cases, the Forward Sensing Camera (FSC) determines that there is a vehicle ahead and the SCBS may operate.

• Objects on the road at the entrance to a curve.

• Vehicles passing in the opposite lane while making a curve.

• Metal objects, bumps, or protruding objects on the road.

• When passing through a toll gate.

• When passing through low gates, narrow gates, car washing machines, or tunnels.

• If you suddenly come close to a vehicle ahead.

• 2-wheeled vehicles, pedestrians, animals or standing trees.

• Vehicle is driven with some of the tires having significant wear.
