Door Locks
WA R N I N G
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep all doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close all the windows and
moonroof, lock the doors and the liftgate
and take the key with you when leaving
your vehicle unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors and the liftgate,
always verify that they are securely closed:
Doors and the liftgate not securely closed
are dangerous, if the vehicle is driven with
a door and the liftgate not securely closed,
the door and the liftgate could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the liftgate is
dangerous. A passing vehicle or a
pedestrian could be hit and cause an
accident.
CAUTION
 Always confirm the conditions around
the vehicle before opening/closing the
doors and the liftgate and use caution
during strong winds or when parked on
an incline. Not being aware of the
conditions around the vehicle is
dangerous because fingers could get
caught in the door and the liftgate or a
passing pedestrian could be hit, resulting
in an unexpected accident or 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 perform best w ith 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 negativel y 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 us ing gasohol of any kind if your vehicle engine
is performing poorly.
 Never add fuel system additive s, 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 problems resulting from the use of the following may not be
covered by the warranty.
•Gasohol containing mo re 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 e xhaust 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 le ad to accumulate on the catalyst inside the
converter or cause the converter to get very ho t. 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 hi gh idle for more than 2 minutes.
 Do not tamper with the emission control syst em. 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 oper ates while the engine is off.
