Head Restraints
▼ Head Restraints
Your vehicle is equipped with head
restraints on all outboard seats and the
rear center seat. The head restraints are
intended to help protect you and the
passengers from neck injury.
WARNING
Always drive with the head restraints
installed when seats are being used
and make sure they are properly
adjusted:
Driving with the head restraints
adjusted too low or removed is
dangerous. With no support behind
your head, your neck could be
seriously injured in a collision.
▼
Height Adjustment
Adjust the head restraint so that the
center is even with the top of the
passenger's ears.

To raise a head restraint, pull it up to
the desired position.
To lower the head restraint, press the
stop-catch release, then push the head
restraint down.

CAUTION
When installing a head restraint,
make sure that it is installed correctly
with the front of the head restraint
facing forward. If the head restraint is

result in injury.
 The head restraints on each of the
front and rear seats are specialized to
each seat. Do not switch around the
head restraint positions. If a head
restraint is not installed to its correct
seat position, the e ffectiveness of the
head restraint during a collision will
be compromised which could cause
injury.

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 during 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.
WARNING
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.

Do not operate a vehicle with a
damaged seat belt:
Using a damaged seat belt is
dangerous. An accident could damage
the belt webbing of the seat belt in
use. A damaged seat belt cannot
provide adequate protection in a
collision. Have an Authorized Mazda
Dealer inspect all seat belt systems in
use during an accident before they are
used again.
Have your seat belts changed
immediately if the pretensioner or
load limiter has been expended:
Always have an Authorized Mazda
Dealer immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, the seat
belt pretensioners and load limiters
will only function once and must be
replaced after any collision that caused
them to deploy. A seat belt with an
expended pretensioner or load limiter
is still better than wearing no seat belt
at all; however, if the seat belt
pretensioners and load limiters are not
replaced, the risk of injury in a collision
will increase.
Positioning the Shoulder Portion of
the Seat Belt:
Improper positioning of the shoulder
portion of the seat belt is dangerous.
Always make sure the shoulder portion
of the seat belt is positioned across
your shoulder and near your neck, but
never under your arm, on your neck, or
on your upper arm.Positioning the Lap Portion of the Seat
Belt:
The lap portion of the seat belt worn
too high is dangerous. In a collision,
this would concentrate the impact
force directly on the abdominal area,
causing serious injury. Wear the lap
portion of the belt snugly and as low as
possible.
CAUTION
Belt retraction may become difficult if
the belts and rings are soiled, so try to
keep them clean. For more details
about cleaning the seat belts, refer to
"Seat Belt Maintenance" (page
6-54).

▼Pregnant Women and Persons with
Serious Medical Conditions
Pregnant women should always wear
seat belts. Ask your doctor for
specific
recommendations.
The lap belt should be worn SNUGLY
AND AS LOW AS POSSIBLE OVER THE
HIPS.
The shoulder belt should be worn
across your shoulder properly, but
never across the stomach area.
Persons with serious medical
conditions also should wear seat belts.
Check with your doctor for any special
instructions regarding speci fic medical
conditions.
▼ Emergency Locking Mode
When the seat belt is fastened, it will
always be in the emergency locking
mode.
In the emergency locking mode, the
belt remains comfortable on the
occupant and the retractor will lock in
position during a collision.
If the belt is locked and cannot be
pulled out, retract the belt once, and
then try pulling it out slowly. If this
fails, pull the belt strongly 1 time and
loosen, then pull it out again slowly.
(Seat Belt with Automatic Locking
Mode)
When the seat belt is fastened, it will
always be in the emergency locking
mode until it is switched to automatic
locking mode by pulling it all the way
out to its full length. If the belt feels
tight and hinders comfortable
movement while the vehicle is stopped
or in motion, it may be in the
automatic locking mode because the
belt has been pulled too far out. To
return the belt to the more
comfortable emergency locking mode,
wait until the vehicle has stopped in a
safe, level area, retract the belt fully to
convert it back to emergency locking
mode and then extend it around you
again.
▼
Automatic Locking Mode (Except
Mexico)
Always use the automatic locking
mode to keep the child-restraint
system from shifting to an unsafe
position in the event of an accident. To
enable seat belt automatic locking
mode, pull it all the way out and
connect it as instructed on the
child-restraint system. It will retract
down to the child-restraint system and
stay locked on it. See the section on
child restraint (page 2-44).
