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.

(Except Mexico)
All of the seat belt retractors are designed to keep the lap/sh oulder belts out of the way when
not in use.
The driver's seat belt has no provisions for child-restraint sy stems 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 b elt retractors operate in two
modes: emergency locking mode, and for child-restraint systems, automatic locking mode.
While we recommend you put all chi ldren in the rear seats, if you must use the front
passenger seat for a child, slide the front passenger seat as f ar back as possible and make
sure any child-restraint sy stem is secured properly.

(Mexico)
All the seats have lap/shoulder belts. These belts have retract ors 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.
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 dangerou s. During a collision, occupants not wearing
seat belts could hit someone or things inside th e 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 wea
r 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 b elts. Check with your doctor
for any special instructions regarding specific medical conditi ons.
▼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 pos ition during a collision.
If the belt is locked and cannot be pulled out, retract the bel t once, and then try pulling it out
slowly. If this fails, pull the belt strongly one time and loos en, then pull it out again slowly.
(Seat Belt with Autom atic 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 ou t to its full length. If the belt
feels tight and hinders comforta ble 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 u ntil the vehicle has stopped
in a safe, level area, retract t he belt fully to convert it back to emergency locking mode and
then extend it around you again.
▼ Automatic Locking Mode*
Always use the automatic locking mode to keep the child-restrai
nt 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 chi ld-restraint system. It will retract
down to the child-restraint system and stay locked on it. See t he section on child restraint
(page 2-20).

(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 when the front passenger occupant
classification sensor detects a passenger
sitting on the front passenger's seat.
For details, refer to the front passenger
occupant classification sensor (page 2-
61).

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, the 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 driver and front
passenger seat belts is dangerous. Without
proper positioning, the pretensioner and
load limiting systems cannot provide
adequate protection in an accident and
this could result in serious injury. For more
details about wearing seat belts, refer to
"Fastening the seat belts" (page 2-15).
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.
Do not modify the components or wiring,
or use electronic testing devices on the
pretensioner system:
Modifying the components or wiring of the
pretensioner system, including the use of
electronic testing devices is dangerous. You
could accidentally activate it or make it
inoperable which would prevent it from
activating in an accident. The occupants or
repairers could be seriously injured.
Properly dispose of the pretensioner
system:
Improper disposal of the pretensioner
system or a vehicle with non-deactivated
pretensioners is dangerous. Unless all
safety procedures are followed, injury could
result. Have an Authorized Mazda Dealer
safely dispose of the pretensioner system or
scrap a pretensioner system equipped
vehicle.

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 2-10.
▼ Using Automatic Locking Mode*
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 2-40).
NOTE
Follow the child-restraint system
manufacturer's instru ctions 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 Restra ints on page 2-10.
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.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-44) carefully.
▼Front Passenger Occupant Classification Sensor
Your vehicle is equipped with a front passenger occupant classi
fication sensor as a part of
the supplemental restraint system. This sensor is equipped in t he front passenger's seat
cushion. This sensor measures th e electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front passenger front and s ide air bags and seat belt
pretensioner system from deployi ng if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivati on indicator light turns on.
Refer to the following table for the front passenger air bag deactivation indicator light
illumination conditions.

This system shuts off the front passenger front and side air ba gs and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light turns on
according to the following table.

The air bag/front seat belt pretensioner system warning light f lashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction. If
this happens, the front passenger front and side air bags and s eat belt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light turns on to r emind you that the front passenger front and side air bags
and seat belt pretensioner will not deploy during a collision.
If the front passenger occupant classification sensor is normal, the indicator light turns on
when the ignition is switched ON. The light turns off after a f ew seconds. Then, the
indicator light turns on or is off under the following conditio ns:

Inside Trunk ReleaseLever (4-Door)
*
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 locki ng 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.
Always keep the car from being a tempting
place to play by latching the rear seats,
doors and the trunk, and keeping the keys
where children can not play with them:
Leaving children or animals unattended in
a parked vehicle is dangerous. Babies left
sleeping and children who lock themselves
in cars or trunks can die very quickly from
heat prostration. Do not leave your
children or pets alone in a car at any time.
Do not leave the car, the rear folding seats
or the trunk unlocked.
▼ Opening the Trunk Lid from the
Inside
Slide the inside trunk release lever in the
direction of the arrow. The lever is made
of material that will
glow for hours in the
darkness of the trunk following a brief
exposure to ambient light.

The inside trunk release lever is located on
the inside of the trunk lid.
