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.

▼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 specific 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 a
nd 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 to o 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 Lockin
g 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).

Front Seat Belt
Pretensioner and Load Limiting Systems
▼Front Seat Belt
Pretensioner and
Load Limiting Systems
For optimum protection, the driver and
front passenger seat belts are equipped
with pretensioner and load limiting
systems. For both these systems to work
properly you must wear the seat belt
properly.

Pretensioners:
When a collision is detected, the
pretensioners deploy simultaneously with
the air bags.
For vehicles with t he front passenger
occupant classification system, the
pretensioners deploy simultaneously with
the air bags when a roll-over is also
detected.
For deployment details, refer to the SRS
Air Bag Deployment Criteria (page
2-68).

The seat belt retractors remove slack
quickly as the air bags are expanding. Any
time the air bags and seat belt
pretensioners have fired they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning Indication/
Warning Light on page 7-32.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning Beep on
page 7-41.
(With Front Passenger Occupant
Classification System)
In addition, the pretensioner system for the
front passenger, like the front and side
passenger air bag, is designed to only
deploy in accordance with the total seated
weight on the front passenger seat.
For details, refer to the front passenger
seat weight sensors (page 2-72).

Load limiter:
The load limiting system releases belt
webbing in a controlled manner to reduce
belt force on the occupant's chest. While
the most severe load on a seat belt occurs
in frontal collisions, th e load limiter has an
automatic mechanical function and can
activate in any accident mode with
sufficient occupant movement.
Even if the pretensioners have not fired,
the load limiting function must be checked
by an Authorized Mazda Dealer.
WA R N I N G
Wear seat belts only as recommended in
this owner's manual:
Incorrect positioning of the seat belts is
dangerous. Without pr oper positioning, the
pretensioner and load limiting systems
cannot provide adequate protection in an
accident and this could result in serious
injury. For more deta ils about wearing seat
belts, refer to "Fastening the Seat Belt"
(page 2-26).

(5–Door)
1. Tether strap
2. Anchor bracket
3. Forward

Always install the head restraint and adjust
it to the appropriate position after
removing the child-restraint system:
Driving with the head restraint removed is
dangerous as impact to the occupant's
head cannot be prevented during
emergency braking or in a collision, which
could result in a serious accident, injury or
death.
Refer to Head Restraints on page 2-17.
▼Using Automatic Locking Mode
(Except Mexico)
Follow these instructions when using a
child-restraint system, unless you are
attaching a LATCH-equipped
child-restraint syst
em to the rear LATCH
lower anchors. Refer to “Using LATCH
Lower Anchor” (page 2-50).
NOTE
Follow the child- restraint system
manufacturer's instructions carefully. If
you are not sure whether you have a
LATCH system or tether, check in the
child-restraint system manufacturer's
instructions and follow them accordingly.
Depending on the type of child-restraint
system, it may use LATCH system instead
of seat belts or if the belt goes across the
child's chest, may recommend against
using automatic locking mode.
1. Make sure the seatback is securely latched by pushing it back until it is
fully locked.
2. Remove the head restraint. However,
when installing a backless booster seat,
always install the vehicle head restraint
to the seat where the backless booster
seat is installed.
Refer to Head Restraints on page 2-17.
3. Secure the child-restraint system with the lap portion of the lap/shoulder belt.
See the manufacturer's instructions on
the child-restraint system for belt
routing instructions.

Inside Trunk Release
Lever (4-door)
*
▼Inside Trunk Release Lever
Your vehicle is equipped with an inside
trunk release lever that provides a means
of escape for children and adults in the
event they become locked inside the trunk.

No matter how careful adults might be
with keys and locking their cars, parents
should be aware that children may be
tempted to play around vehicles and use
the trunk as a hiding place.

Adults are advised to familiarize
themselves with the
operation and location
of the inside trunk release lever so that all
children can be told about it in an
appropriate way, keeping in mind that
most vehicles do not have such levers.
WA R N I N G
Close the trunk lid, be sure the seat backs
are latched and do not allow children to
play inside the vehicle:
Leaving the trunk lid open or leaving
children in the vehicle with the keys is
dangerous. Children could open the trunk
lid and climb inside resulting in possible
injury or death from heat exposure.
