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.

WA R N I N G
Do not rely completely on the LDWS:
The LDWS system is not designed to
compensate for a driver’s lack of caution
and relying too much on the system
could lead to an accident.
 The functions of the LDWS have
limitations. Always stay on course using
the steering wheel and drive with care.
CAUTION
Heed the following cautions so that the
LDWS can operate normally.
Do not modify the vehicle's suspensions.
 Always use wheels of the
specified type
and size for the front and rear wheels.
Consult an Authorized Mazda Dealer for
tire replacement.
NOTE
The system may not operate normally
under the following conditions.

visible because of di rt 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.

Rear Cross Traffic Alert (RCTA)
If there is the possibility of a collision
with an approaching vehicle while the
rear view/rear wide view is displayed, a
warning is displayed on the center
display.
The Rear Cross Traffic Alert (RCTA)
uses rear side radar sensor to detect
vehicles approaching from the rear left
and right sides of the vehicle, and it
assists the driver in checking the rear of
the vehicle while reversing by flashing
the Blind Spot Monitoring (BSM)
warning lights and activating the
warning sound.
Refer to Rear Cross Traffic Alert
(RCTA) on page 4-114.
360°View Monitor Range
1. Cameras
2. Ultrasonic sensors
3. Front/Rear side radar sensors
WA R N I N G
Always confirm the safety of the area
around the vehicle with the mirrors and
directly with your eyes when driving:
The 360°View Monitor is an auxiliary device
which assists the driver in checking the
safety of the area around the vehicle.
The shooting range of the cameras and
detection range of the sensors are limited.
For example, the areas in black at the front
and rear of the vehicle image and the
seams where each of the camera images
merge are blind spots where an obstruction
may not be visible. In addition, the
extended vehicle width lines and projected
vehicle path lines are only to be used as
references, and the images on the screen
may differ from the actual conditions.
CAUTION
 Do not use the 360°View Monitor under
any of the following conditions.
 Icy or snow-covered roads.
 Tire chains or a te mporary spare tire is
installed.
 The front doors or the rear doors is not
fully closed.
 The vehicle is on a road incline.
 The door mirrors are retracted.
 Do not hit the front/rear camera, front/
rear bumper, and door mirrors forcefully.
The camera position or installation angle
may shift.
 The cameras are of a waterproof
structure. Do not disassemble, modify, or
remove a camera.
