Inside Trunk Release

Lever (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 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.

WARNING

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.

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 minimum.

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 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 serious engine damage.

CAUTION

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.

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 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 alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems 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 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 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)

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.

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 open 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 vehicle 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.

Fuel-Filler Lid and Cap

WARNING

When removing the fuel-filler cap, loosen
the cap slightly and wait for any hissing to
stop, then remove it:
Fuel spray is dangerous. Fuel can burn skin
and eyes and cause illness if ingested. Fuel
spray is released when there is pressure in
the fuel tank and the fuel-filler cap is
removed too quickly.

Before refueling, stop the engine, and
always keep sparks and flames away from
the filler neck:
Fuel vapor is dangerous. It could be ignited
by sparks or flames causing serious burns
and injuries.
Additionally, use of the incorrect fuel-filler
cap or not using a fuel-filler cap may result
in a fuel leak, which could result in serious
burns or death in an accident.

Do not continue refueling after the fuel
pump nozzle shuts off automatically:
Continuing to add fuel after the fuel pump
nozzle has shut off automatically is
dangerous because overfilling the fuel tank
may cause fuel overflow or leakage. Fuel
overflow and leakage could damage the
vehicle and if the fuel ignites it could cause
a fire and explosion resulting in serious
injury or death.

CAUTION

(U.S.A. and Canada)
Always use only a genuine Mazda fuel-filler
cap or an approved equivalent, available at
an Authorized Mazda Dealer. The wrong
cap can result in a serious malfunction of
the fuel and emission control systems. It
may also cause the check engine light in
the instrument cluster to illuminate.

reinstall it correctly. After the cap has been
correctly installed, the fuel cap warning
light may continue to illuminate until a
number of driving cycles have been
completed. A drive cycle consists of starting
the engine (after four or more hours with
the engine off) and driving the vehicle on
city and highway roads.
Continuing to drive with the check fuel cap
warning light illuminated could cause the
check engine light to illuminate as well.

Power Windows

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 holding up the power window switch:
Blocking the power window just before it
reaches the fully closed position or while
holding up the power window switch is
dangerous.
In this case, the jam-safe function cannot
prevent the window from closing all the
way. If fingers are caught, serious injuries
could occur.

NOTE
When driving with only one of the rear
windows open, your ears might experience
a resonating sound. However, this does not
indicate a problem. The sound can be
