Inside Trunk ReleaseLever
*
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, do not allow children to
play inside the trunk:
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 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 trunk unlocked.
â–¼ 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
â–¼Fuel 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.

To achieve maximum engine performance, use the specified fuel.
Fuel Octane Rating*1 (Anti-knock index)
Premium unleaded fuel 91 [(R+M)/2 method] or above (96 RON or ab ove)
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
Regular unleaded fuel with an octane rating from 87 to 90 (91 t o 95 RON) can be used, but
this will reduce perform ance slightly, such as reduced engine o utput, and engine knocking.
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 other than a Mazda genuine product, 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.
ï‚·Gasohol containing more than 10 % ethanol.
ï‚·Gasoline or gasohol containing methanol.
ï‚·Leaded fuel or leaded gasohol.

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
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.
(U.S.A. and Canada)
It may also cause the check engine light in
the instrument cluster to illuminate.
â–¼ Refueling
Before refueling, close both the doors,
windows, and the trunk lid, and switch the
ignition OFF.
1. To open the fuel-filler lid, pressed the
edge of the lid with the doors
unlocked.

NOTE
The fuel-filler lid operates in
conjunction with the door locking/
unlocking mechanism.
2. To remove the fuel-filler cap, turn it
counterclockwise.

If the fuel-filler lid is closed after
locking the doors, the fuel-filler lid
cannot be locked.
CAUTION
(U.S.A. and Canada)
If the check fuel cap warning light
illuminates, the fuel-filler cap may not be
properly installed. If the warning light
illuminates, park your vehicle safely off the
right-of-way, remove the fuel-filler cap and
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.
