Limitations to SRS Air Bag
▼Limitations to SRS Air Bag
In severe collisions such as those
described previously in "SRS Air Bag
Deployment Criteria", the applicable
SRS air bag equipment will deploy.
However, in some accidents, the
equipment may not deploy depending
on the type of collision and its severity.

Limitations to front/near front
collision detection:
The following illustrations are
examples of front/near front collisions
that may not be detected as severe
enough to deploy the SRS air bag
equipment.

Impacts involving trees or poles

Frontal offset impact to the vehicle

Rear-ending or running under a
truck's tail gate
Limitations to side collision detection:
The following illustrations are
examples of side collisions that may
not be detected as severe enough to
deploy the SRS air bag equipment.

Side impacts involving trees or poles

A front passenger is seated as shown
in the following figure:A rear passenger pushes up on the
front passenger seat with their feet.
 Luggage or other items placed under
the front passenger seat or between
the front passenger seat and driver
seat that push up the front passenger
seat bottom.
 Any accessories which might
decrease the total seated weight on
the front passenger seat are attached
to the front passenger seat.
The front passenger front and side air
bags and knee air bags, and the seat
belt pretensioner system will
deactivate if the front passenger air
bag deactivation indicator light
illuminates.

Do not increase the total seated
weight on the front passenger seat:
When an infant or small child sits on
the front passenger seat, increasing the
total seated weight on the front
passenger seat is dangerous. The front
passenger seat we ight sensors will
detect the increased total seated
weight, which could result in the
unexpected deployment of the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system in an accident and
may cause serious injury. Increasing the
total seated weight on the front
passenger seat could result in the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system deployment in an
accident under the following
conditions, for example:
 Luggage or other items are placed on
the seat with the child in the
child-restraint system.

Liftgate
▼Liftgate
WARNING
Never allow a person to ride in the
luggage compartment:
Allowing a person to ride in the
luggage compartment is dangerous.
The person in the luggage
compartment could be seriously
injured or killed during sudden braking
or a collision.
Do not drive with the liftgate open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate in a
moving vehicle will cause exhaust gas
to be drawn into the cabin. This gas
contains CO (carbon monoxide),
which is colorless,
odorless, and highly
poisonous, and it can cause loss of
consciousness and death. Moreover,
an open liftgate could cause occupants
to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage
compartment:
Otherwise, the luggage may move or
collapse, resulting in injury or an
accident. In addition, do not load
luggage higher than the seatbacks. It
may affect the side or rear field of view.
Additionally, if the air bags deploy, the
cargo may scatter which could result in
serious injury or death.
CAUTION
 Before opening the liftgate, remove
any snow and ice accumulation on it.
Otherwise, the liftgate could close
under the weight of the snow and ice
resulting in injury.
 Be careful when opening/closing the
liftgate during strong winds. If a
strong gust blows against the liftgate,
it could close suddenly resulting in
injury.
 Fully open the liftgate and make sure
that it stays open. If the liftgate is
only opened partially, it could slam
shut by vibration or wind gusts
resulting in injury.
 When loading or unloading luggage
in the luggage compartment, turn
off
the engine. Otherwise, you could get
burned by the heat of the exhaust
gas.
 Be careful not to apply excessive
force to the damper stay on the
liftgate such as by putting your hand
on the stay. Otherwise, the damper
stay may bend and
affect the liftgate
operation.

▼Emission Control System
This vehicle is equipped with an
emission control system (the catalytic
converter is part of this system) that
enables the vehicle to comply with
existing exhaust emissions
requirements.
WARNING
Never park over or near anything
flammable:
Parking over or near anything
flammable, such as dry grass, is
dangerous. Even with the engine
turned off, the exhaust system remains
very hot after normal use and could
ignite anything
flammable. A resulting
fire could cause serious injury or death.
CAUTION
Ignoring the following precautions
could cause lead to accumulate on the
catalyst inside the converter or cause
the converter to get very hot. Either
condition will dama ge the converter
and cause poor performance.
 USE ONLY UNLEADED FUEL.
 Do not drive your Mazda with any
sign of engine malfunction.
 Do not coast with the ignition
switched off.
 Do not descend steep grades in gear
with the ignition switched off.
 Do not operate the engine at high
idle for more than 2 minutes.
 Do not tamper with the emission
control system. All inspections and
adjustments must be made by a
qualified technician.
 Do not push-start or pull-start this
vehicle.
NOTE
Under U.S. federal law, any
modification to the
original-equipment emission control
system before the first sale and
registration of a vehicle is subject to
penalties. In some states, such modification made on a used vehicle
is also subject to penalties.
While the engine is off, the sound of
a valve opening and closing can be
heard at the rear of the vehicle,
however this does not indicate an
abnormality. The vehicle has a
self-checking device and it operates
while the engine is off.
▼ Engine Exhaust (Carbon
monoxide)
WARNING
Do not drive your vehicle if you smell
exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This
gas contains carbon monoxide (CO),
which is colorless, odorless, and
poisonous. When inhaled, it can cause
loss of consciousness and death. If you
smell exhaust gas inside the vehicle,
keep all windows fully open and
contact an Authorized Mazda Dealer
immediately.
Do not run the engine when inside an
enclosed area:
Running the engine inside an enclosed
area, such as a garage, is dangerous.
Exhaust gas, which
contains poisonous
carbon monoxide, could easily enter
the cabin. Loss of consciousness or
even death could occur.

▼Po we r Wi n d o w s
The windows can be opened/closed
by operating the power window
switches.
WARNING
Make sure the opening is clear before
closing a window:
Closing a power window is dangerous.
A person's hands, head, or even neck
could be caught by the window and
result in serious injury or even death.
This warning applies especially to
children.
Never allow children to play with
power window switches:
Power window switches that are not
locked with the power window lock
switch would allow children to operate
power windows unintentionally, which
could result in serious injury if a child's
hands, head or neck becomes caught
by the window.
Make sure nothing blocks the window
just before it reaches the fully closed
position or while fully holding up the
power window switch:
Blocking the power window just before
it reaches the fully closed position or
while fully holding up the power
window switch is dangerous.
In this case, the jam-safe function may
not prevent the window from closing
all the way. If
fingers are caught,
serious injuries could occur.
Do not let a child put a hand or head
out of the window while driving the
vehicle:
If the person's hand or head hits
something outside the vehicle, or
sudden braking is applied, it could
result in serious injury or death.
NOTE
When driving with only 1 of the rear
windows open, your ears might
experience a resonating sound.
However, this does not indicate a
problem. The sound can be reduced
by slightly opening a front window or
by changing the size of the rear
window opening.
