Fuel-Filler Lid and Cap
WA R N I N G
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 ge nuine 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 all the doors,
windows, and the liftgate, and switch the
ignition OFF.
1. To open the fuel-filler lid, pull the
remote fuel-filler lid release.

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pre ssure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when th e low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduce s fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct ti re pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale wi ll flash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle th at prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
 To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously regi ster a rapid tire deflation or blow out.
▼System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire
pressure sensor to
the receiver unit.
When using the following devices in the
vehicle that may cause radio
interference with the receiver unit.
A digital device such as a personal
computer.
A current converter device such as a
DC-AC converter.
When excess snow or ice adheres to the
vehicle, especially around the wheels.
When the tire pressu re sensor batteries
are exhausted.
When using a wheel with no tire
pressure sensor installed.
When using tires with steel wire
reinforcement in the sidewalls.
When using tire chains.

Remarks:
*1 The engine oil and filter must be changed at least once a year or within 12,000 km (7,500 miles) since last
engine oil and filter change. Re set the engine oil data whenever replacing the engine oil regardless of the
message/wrench indicator light display.
*2 Use of FL-22 is recommended when replacing engine coolant. Using engine coolant other than FL-22 may
cause serious damage to the engine and cooling system.
*3 According to state/provincial and federal regulations, failure to perform maintenance on these items will not
void your emissions warranties. H owever, Mazda recommends that all maintenance services be performed at
the recommended time or mileage/kilometer period to ensure long -term reliability.
*4 If this component has been submerged in water, the oil should be replaced.*5 Check the tire repair fluid expiration date every year when performing the periodic maintenance. Replace the
tire repair fluid bottle with ne w one before the expiration dat e.

Owner Maintenance Precautions
The owner or a qualified service technician should make these vehicle inspections at the
indicated intervals to ensure safe and dependable operation.

Bring any problem to the attention of an Authorized Mazda Deale r or qualified service
technician as soon as possible.
When Refueling
Brake fluid level (page 6-27)
Engine coolant level (page 6-25)
Engine oil level (page 6-24)
Washer fluid level (page 6-27)
At Least Monthly
Tire inflation pressures (page 6-38)
At Least Twice a Year (For Example, Every Spring and Fall)
You can do the following schedu led maintenance items if you hav e some mechanical ability
and a few basic tools and if you closely follow the directions in this manual.
Engine coolant (page 6-25)
Engine oil (page 6-23)

Improper or incomplete service may result in problems. This sec tion gives instructions only
for items that are easy to perform.

As explained in the Introduction (page 6-2), several procedures can be done only by a
qualified service technician with special tools.

Improper owner maintenance during the warranty period may affec t warranty coverage.
Refer to Introduction (page 6-2) for owner's responsibility in protecting your investment.
For details, read the separate Mazda Warranty statement provide d with the vehicle. If you
are unsure about any servicing or maintenance procedure, have i t done by an Authorized
Mazda Dealer.

There are strict environmental laws regarding the disposal of w aste oil and fluids. Please
dispose of your waste properly and with due regard to the envir onment.

We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized
Mazda Dealer.

6. Insert a new battery with the positivepole facing up, and then cover the
battery with the battery cap.
7. Close the cover.
8. Reinsert the auxiliary key.
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 9-8) 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 9-8.
