Seat Belt Precautions
▼Seat Belt Precautions
Seat belts help to decrease the possibility
of severe injury during accidents and
sudden stops. Mazda recommends that the
driver and all passengers always wear seat
belts.

(Mexico)
All the seats have lap/shoulder belts.
These belts have retractors with inertia
locks that keep them
out of the way when
not in use. The locks allow the belts to
remain comfortable on users, but they will
lock in position du ring a collision.

(Except Mexico)
All of the seat belt retractors are designed
to keep the lap/shoulder belts out of the
way when not in use.
The driver's seat belt has no provisions for
child-restraint systems and has only an
emergency locking mode. The driver may
wear it comfortably, and it will lock during
a collision.
However, the front passenger's seat and all
rear lap/shoulder belt retractors operate in
two modes: emergency locking mode, and
for child-restraint systems, automatic
locking mode. While we recommend you
put all children in the rear seats, if you
must use the front passenger seat for a
child, slide the front passenger seat as far
back as possible and make sure any
child-restraint system is secured properly.
WA R N I N G
Always wear your seat belt and make sure
all occupants are properly restrained:
Not wearing a seat belt is extremely
dangerous. During a collision, occupants
not wearing seat belts could hit someone
or things inside the vehicle or even be
thrown out of the vehicle. They could be
seriously injured or even killed. In the same
collision, occupants wearing seat belts
would be much safer.
Do not wear twisted seat belts:
Twisted seat belts are dangerous. In a
collision, the full width of the belt is not
available to absorb the impact. This puts
more force on the bones beneath the belt,
which could cause serious injury or death.
So, if your seat belt is twisted, you must
straighten the seat belt to remove any
twists and to allow the full width of the belt
to be used.
Never use one seat belt on more than one
person at a time:
Using one seat belt for more than one
person at a time is dangerous. A seat belt
used in this way cannot spread the impact
forces properly and the two passengers
could be crushed together and seriously
injured or even killed. Never use one belt for
more than one person at a time and always
operate the vehicle with each occupant
properly restrained.

NOTE
The system may not operate normally
under the following conditions.
The white (yellow) lane lines are less
visible because of dirt or paint flaking.
White (yellow) lane lines are 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
might be multiple white (yellow) lane
lines, or they are interrupted.
The camera picks up an obscure line,
such as a temporary line being used for
construction, or because of shade,
unmelted snow, or grooves filled with
water.
The surrounding brightness suddenly
changes such as when entering or
exiting a tunnel.
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 width of a lane is excessively
narrow.
The vehicle is driven on roads with tight
curves.
Heavy luggage is loaded in the luggage
compartment or on the rear seat causing
the vehicle to tilt.
The vehicle is driven through a fork in
the road or a junction.
The shade of a guardrail parallel to a
white (yellow) lane line is cast on the
road.

weakened because of dirt or the optical
axis is deviated at night.
The road is excessively uneven.
The vehicle is shaken after hitting a
road bump.
A vehicle in front of your vehicle is
running near a white (yellow) lane line
making it less visible.
The windshield is dirty or foggy.

▼When the System Operates
When the ignition is switched ON, the
i-ACTIVSENSE status symbol (warning/
risk avoidance suppor
t system) (white)
turns on and the system goes on standby.
NOTE
If the i-ACTIVSENSE status symbol
(warning/risk avoidance support system)
(white) does not turn on, the system is
canceled using the i-ACTIVSENSE switch
or the personalization feature.
Operation conditions
When all of the foll owing conditions are
met, the i-ACTIVSENSE status symbol
(warning/risk avoidance support system)
on the multi-information display changes
from white to green and the system
becomes operational.

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 rear
side radar sensor is set at the road
width of expressways.

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
