Essential Safety Equipment
Seats
Always leave your car locked and keep the car keys safely away from children (4–
Door):Leaving your car unlocked or the keys in reach of children is dangerous. Children who find
their way into the trunk through an unlocked rear seatback or an open trunk can become
accidentally locked in the trunk. This could result in death or brain damage from heat
prostration, particularly in the summer. Always lock the doors and the trunk, and as an
added measure, keep the rear seatbacks locked, whether you have children in your home
or not.
CAUTION
 When operating a seat, be careful not to put your hands or fingers near the moving parts of
the seat or on the side trim to prevent injury. When moving the seats, make sure there is no cargo in the surrounding area. If the cargo
gets caught it could damage the cargo. (Manual Seat)
When moving the seats forward and rearward or returning a rear-reclined seatback to its
upright position, make sure you hold onto the seatback with your hand while operating. If
the seatback is not held, the seat will move suddenly and could cause injury.
NOTE
 When returning a rear seat to its original position, place the seat belt in its normal
position. Verify that the seat belt pulls out and retracts.
 (Power Seat)
The seat-bottom power adjustment is operated by motors. Avoid extended operation
because excessive use can damage the motors.
 To prevent the battery from running down, avoid using the power adjustment when the
engine is stopped. The adjuster uses a large amount of electrical power. Do not use the switch to make more than one adjustment at a time.

Doors and Locks
Liftgate/Trunk Lid
WARNING
Never allow a person to ride in the
luggage compartment/trunk:Allowing a person to ride in the
luggage compartment/trunk is
dangerous. The person in the luggage
compartment/trunk could be seriously
injured or killed during sudden braking
or a collision.
Do not drive with the liftgate/trunk lid
open: Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate/trunk lid
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/trunk lid 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.
CAUTION
 Before opening the liftgate/trunk lid,
remove any snow and ice accumulation
on it. Otherwise, the liftgate/trunk lid
could close under the weight of the snow
and ice resulting in injury.
 Be careful when opening/closing the
liftgate/trunk lid during strong winds.
If a strong gust blows against the
liftgate/trunk lid, it could close suddenly
resulting in injury.
 Fully open the liftgate/trunk lid and
make sure that it stays open. If the
liftgate/trunk lid 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/trunk, 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.

Fuel and Emission
Fuel and Engine Exhaust Precautions
Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a min\
imum.

This vehicle will perform best with fuel listed in the table.

Fuel Octane Rating * (Anti-knock index)
Regular unleaded fuel 87 [(R
M)/2 method] or above (91 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline stat\
ion pumps.

Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission control
system performance and could also cause engine knocking and serious engi\
ne damage.
CAUTION
 ¾ USE ONLY UNLEADED FUEL. Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 ¾ This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or
if the gasoline contains any methanol. Stop using gasohol of any kind if your vehicle engine
is performing poorly.
 ¾  Never add fuel system additives, otherwise the emission control system could be damaged.
Consult an Authorized Mazda Dealer for details.

Gasoline blended with oxygenates such as alcohol or ether compounds are \
generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline containing alc\
ohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the fol\
lowing may not be
covered by the warranty.
 y  Gasohol containing more than 10 % ethanol. y Gasoline or gasohol containing methanol. y Leaded fuel or leaded gasohol.

Before Driving
Fuel and Emission
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 e\
xhaust 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 damage 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 your 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\
hear d 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.
