i-ACTIVSENSE

The timing in which the system switches the headlights changes under the following conditions. If the system does not switch the headlights appropriately, manually switch between high and low beams according to the visibility as well as road and traffic conditions.

• When there are sources of light in the area such as street lamps, illuminated signboards, and traffic signals.

• When there are reflective objects in the surrounding area such as reflective plates and signs.

• When visibility is reduced under rain, snow and foggy conditions.

• When driving on roads with sharp turn or hilly terrain.

• When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim or not illuminated.

• When there is sufficient darkness such as at dawn or dusk.

• When the luggage compartment is loaded with heavy objects or the rear passenger seats are occupied.

• When visibility is reduced due to a vehicle in front of you spraying water from its tyres onto your windscreen.

• If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and indicator light). Steer the vehicle adequately to drive the vehicle to the centre of the lane.

• When the direction indicator lever is operated for a lane change, the LDWS warning is automatically cancelled. The LDWS warning becomes operable when the direction indicator lever is returned and the system detects the white or yellow lines.

• If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the vehicle moves close to a white or yellow line, the system determines that the driver is making a lane change and the LDWS warning is automatically cancelled.

• The LDWS may not operate during the period immediately after the vehicle has deviated from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly within a short period of time.

• The LDWS does not operate if it does not detect the white or yellow lines of the traffic lane.

• Under the following conditions, the LDWS may not be able to detect white or yellow lines correctly and the LDWS may not operate correctly.

  • If an object placed on the instrument panel is reflected in the windscreen and picked up by the camera.

  • Heavy luggage is loaded in the luggage compartment or on the rear seat and the vehicle is inclined.

  • The tyre pressures are not adjusted to the specified pressure.

  • When the vehicle is driven on the entry and exit to or from the rest area or tollgate of a highway.

  • The white or yellow lines are less visible because of dirt or paint flaking.

  • The vehicle ahead is running near a white or yellow line and the line is less visible.

  • A white or yellow line is less visible because of bad weather (rain, fog, or snow).

  • The vehicle is driven on a temporary lane or section with a closed lane due to construction.

  • A misleading line is picked up on the road such as a temporary line for construction, or because of shade, lingering snow, or grooves filled with water.

  • The surrounding brightness suddenly changes such as when entering or exiting a tunnel.

  • The illumination of the headlights is weakened because of dirt or the optical axis is deviated.

  • The windscreen is dirty or foggy.

  • Back-light is reflecting from the road surface.

  • The road surface is wet and shiny after rain, or there are puddles on the road.

  • The shade of a guardrail parallel to a white or yellow line is on the road.

  • The width of a lane is excessively narrow or wide.

  • The road is excessively uneven.

  • The vehicle is shaken after hitting a road bump.

  • There are two or more adjacent white or yellow lines.

  • There are various road markings or lane markings of various shapes near an intersection.

• The Blind Spot Monitoring (BSM) system will operate when all of the following conditions are met:

  • The ignition is switched ON.

  • 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 5 km/h (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.

• 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.

  • 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.

• The Blind Spot Monitoring (BSM) warning lights may turn on in reaction to stationary objects on the road or the roadside such as guardrails, tunnels, sidewalls, and parked vehicles.



• 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.

• For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork, and replacement near the radar sensors, consult an Authorised Mazda Dealer.

• Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will be blocked causing the system to not operate normally.
