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 tires onto your windshield.

• 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 indicator light is turned off.

  • The selector lever is shifted to reverse (R) 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 two 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 two 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 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 by changing the setting on the center display.

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

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

• When the turn signal lever is operated for a lane change, the LAS & LDWS is automatically disabled. The LAS & LDWS becomes operational again when the turn signal lever is returned and the system detects white (yellow) lane lines while the vehicle is being driven normally within its vehicle lane.

• If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the vehicle moves close to a white (yellow) line, the system determines that the driver is making a lane change and the LAS & LDWS operation is temporarily canceled. The LAS & LDWS becomes operational again when the system detects white (yellow) lane lines while the vehicle is being driven normally within its vehicle lane.

• If the vehicle deviates from its lane repeatedly within a short period of time, the LAS & LDWS may not operate.

• When white (yellow) lane lines are not detected, the LAS & LDWS does not operate.

• Under the following conditions, the LAS & LDWS may not be able to detect white (yellow) lane lines correctly and it may not operate normally.

  • If an object placed on the dashboard is reflected in the windshield and picked up by the camera.

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

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

  • Tires other than conventional tires are equipped.

  • Vehicle is driven on an intersection or junction, or on a forked road.

  • The white (yellow) lane lines are less visible because of dirt or fading/patchiness.

  • A vehicle in front of your vehicle is running near a white (yellow) lane line making it less visible.

  • A white (yellow) lane 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 resulting from construction where there may be multiple white (yellow) lane lines or they are interrupted.

  • 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 windshield is dirty or foggy.

  • The windshield, camera is fogged (water droplets).

  • Back-light is reflected off 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 (yellow) lane line is cast on the road.

  • The width of the driving lane is narrow or wide.

  • Driving on roads with tight curves.

  • The road is excessively uneven.

  • The vehicle is shaken after hitting a road bump.

  • There are 2 or more adjacent white (yellow) lane lines.

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