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.
▼ 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.

4. Insert the refueling nozzle all the wayand begin refueling. Pull out the
refueling nozzle a fter the refueling
stops automatically.
5. To close the fuel-filler cap, turn it clockwise until a click is heard.
6. To close, press the fuel-filler lid until a
click sound is heard.

7. Make sure to lock both the doors whenleaving the vehicle.
Refer to Door Locks on page 3-12.
NOTE
Lock the doors after closing the
fuel-filler lid.
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.

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-9) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-9.
Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly when the
tires are cold. Maintain recommended
pressures for the best
ride, handling, and
minimum tire wear.
Refer to the specification charts (page
9-9).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequen tly needs inflating,
have it inspected.

Pretensioner System Warning Light A system malfunction is indicated
if the warning light constantly flashes, constantly illu‐
minates or does not illuminate a t all when the ignition is switched ON. If any of these oc‐
cur, consult an Authorized Mazda Dealer as soon as possible. The system may not operate
in an accident.WA R N I N G
Never tamper with the air bag/pretensioner systems and always have an Authorized Mazda
Dealer perform all servicing and repairs:
Self-servicing or tampering with the systems is dangerous. An air bag/pretensioner could
accidentally activate or become disabled causing serious injury or death.
