WARNING
Always check the surrounding area visually before making an actual lane change:
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 indicator light, the warning sound and the
warning screen indicator display may not activate or they 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.
NOTE
The Blind Spot Monitoring (BSM) will operate when all of the following conditions
are met:
The ignition is switched ON.
The Blind Spot Monitoring (BSM) OFF indicator light in the instrument cluster is
turned off.
The vehicle speed is about 30 km/h (19 mph) or faster.
The Blind Spot Monitoring (BSM) will not operate under the following circumstances.
The vehicle speed falls below about 25 km/h (15 mph) even though the Blind Spot
Monitoring (BSM) OFF switch 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
Repairer as soon as possible.
Some problem with the system including the Blind Spot Monitoring (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.

When Driving
i-ACTIVSENSE
NOTE
Under the following conditions, the radar sensors (rear) cannot detect target objects or
it may be dif ¿ cult 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) 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 case, the À ashing of the Blind Spot Monitoring (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.
The turning radius is small (making a sharp turn, turning at intersections).
When there is a difference in the height between your driving lane and the adjacent
lane.
Directly after the Blind Spot Monitoring (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.

NOTE
Speed limit signs (including auxiliary signs)
When the vehicle speed is about 1 km/h (0.6 mph) or faster, the speed limit sign is
displayed when any one of the following conditions are met.
The Forward Sensing Camera (FSC) recognises a speed limit sign as a sign targeted
for your vehicle and the vehicle passes it.
The speed limit sign stored in the navigation system is read (if the Forward Sensing
Camera (FSC) does not recognise a speed limit sign).
Inclement weather speed limit signs are displayed when all of the following conditions
are met.
The vehicle speed is about 1 km/h (0.6 mph) or more.
The Forward Sensing Camera (FSC) recognises an inclement weather speed limit
sign as a sign targeted for your vehicle and the vehicle passes it.
The inclement weather speed limit sign is lower than the currently displayed speed
limit sign.
The windscreen wipers are operated.
In the following cases, display of the speed limit sign stops.
The Forward Sensing Camera (FSC) recognises the speed limit sign and the vehicle
is driven for a certain distance after passing the sign.
Each sensor determines that the vehicle has changed direction of travel. (The display
of a speed limit sign does not stop even if the vehicle changes lanes while a "ZONE"
auxiliary sign is displayed.)
The Forward Sensing Camera (FSC) recognises a new speed limit sign which differs
from the previous one (displays the new speed limit sign).
The speed limit sign stored in the navigation system is not read within a certain
period of time (if the Forward Sensing Camera (FSC) does not recognise a speed
limit sign, the speed limit sign stored in the navigation system is displayed).
The vehicle speed exceeds the displayed speed limit sign by 30 km/h (19 mph)
or more after a certain period of time has elapsed since the speed limit sign
was displayed. (Except when there is information for the speed limit sign in the
navigation system)

*Some models.
Distance Recognition Support System (DRSS) *
The Distance Recognition Support System (DRSS) measures the distance between your
vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is about 30
km/h (19 mph) or faster, and if your vehicle approaches a vehicle ahead more closely than
what is appropriate for maintaining distance between the vehicles according to the vehicle
speed, a noti ¿ cation in the active driving display is indicated to advise you to keep a safe
distance from the vehicle ahead.
WARNING
Do not rely completely on the Distance Recognition Support System (DRSS) and always
drive carefully:
The Distance Recognition Support System (DRSS) provides advice for safer driving and
noti ¿ es the driver of a recommended, safer distance to maintain with a vehicle ahead.
The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead,
the weather conditions, and the traf ¿ c conditions. Therefore, if the accelerator and
brake pedals are not operated correctly it could lead to an accident. Always verify the
safety of the surrounding area and depress the brake pedal or accelerator pedal while
keeping a safer distance from vehicles ahead or on-coming vehicles.
NOTE
The Distance Recognition Support System (DRSS) operates when all of the following
conditions are met:
The ignition is switched ON.
The Distance Recognition Support System (DRSS) is on.
The selector lever is in a position other than reverse (R).
The vehicle speed is 30 km/h or faster (19 mph or faster).
The objects which activate the system are 4-wheeled vehicles.
The Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
The Distance Recognition Support System (DRSS) system may not operate normally
under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.
The vehicle ahead is travelling at an extremely slow speed.
The system does not operate with the following objects:
Vehicles approaching in the opposite direction.
Stationary objects (stopped vehicles, obstructions)
