Liftgate
WA R N I N G
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.
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.
Damper stay

Do not modify or replace the liftgate
damper stay. Consult an Authorized
Mazda Dealer if a liftgate damper stay is
deformed or damaged for reasons such
as a collision or if there is some other
problem.

Do not place anything on top of the cover:
Placing luggage or other cargo on top of
the luggage compartment cover is
dangerous. During sudden braking or a
collision, the cargo could become a
projectile that could hit and injure
someone. The vehicl
e has a light weight
luggage compartment cover to keep the
contents of your luggage area out of sight;
it will not retain heavy objects that are not
tied down in an accident such as a rollover.
Tie down all heavy objects, whether
luggage or cargo, using the tie down
hooks.
Make sure luggage and cargo are secured
before driving:
Not securing cargo while driving is
dangerous as it could move or be crushed
during sudden braking or a collision and
cause injury.

Fuel and Engine Exhaust Precautions
▼Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use O
NLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

This vehicle will per form 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 gaso line station 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 ser ious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 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.
 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 compo unds 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 conta ining alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability pr oblems resulting from the use of the following may not be
covered by the warranty.
•Gasohol containing more than 10 % ethanol.
•Gasoline or gasohol containing methanol.
•Leaded fuel or leaded gasohol.

▼Emission Control System
This vehicle is equipp
ed with an emission co ntrol system (the catalytic converter is part of
this system) that enables the ve hicle to comply with existing exhaust emissions
requirements.
WA R N I N G
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 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)
WA R N I N G
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas contai
ns 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 a ll 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.
Open the windows or adjust the heating or cooling system to draw fresh air when idling the
engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows closed and the
engine running for a long time even in an op en area, exhaust gas, which contains poisonous
carbon monoxide, could enter the cabin. Loss of consciousness or even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe, before
starting the engine:
Running the engine when a vehi cle is stopped in deep snow is dangerous. The exhaust pipe
could be blocked by the snow, allowing exhaust gas to enter the cabin. Because exhaust gas
contains poisonous carbon monoxide, it could cause loss of consciousness or even death to
occupants in the cabin.
