qHow the Side and Curtain Air Bags Workí
When air bag crash sensors detect a side impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the side and curtain air bags and after the inflation, the side
and curtain air bags quickly deflate. However, the side bag system for the front passenger
is designed to only deploy in accordance with the total seated weight on the front passenger
seat.
The side and curtain air bags will function only once. After that,the side and curtain air
bags will not work again and must be replaced.Only an Authorized Mazda Dealer can
replace the systems.
The side and curtain air bags will deploy only on the
side the vehicle receives the force of the impact.
qAir Bag Activation/Deactivation
NOTE
If the front passenger seat weight sensors detect a total seated weight on the front
passenger seat is less than approximately 42 kg (93 lb), the front passenger front and side
air bags and seat belt pretensioner may not deploy (page 2-49), but the curtain air bags
may deploy.

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.
2.3-liter turbocharger engine
Your Mazda will perform best with fuel listed in the table.
Fuel Octane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed for and requires use of premium unleaded fuel. If 91 octane fuel [
(R+M)/2 method] (96RON) is not available, gasoline as low as 87 octane [ (R+M)/2
method] (91RON) can be used temporarily for emergency purposes. Use of gasoline lower
than 91 octane [ (R+M)/2 method] (96RON) can decrease performance during its use.
Refueling the vehicle with the correct octane fuel a couple of times will restore vehicle
performance.
Except 2.3-liter turbocharger engine
Your Mazda 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) could cause the emission control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
CAUTION
lUSE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will
accumulate on the oxygen sensor and the catalyst inside the converter. This will result
in a malfunction of the emission control system, causing poor performance.
lYour vehicle can only use oxygenated fuels containing no more than 10% ethanol by
volume. Damage to your 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.
lNever add fuel system additives. Never add cleaning agents other than those specified
by Mazda. Other cleaning agents and additives may damage the system. Consult an
Authorized Mazda Dealer.

Press the switch again to turn the TCS/
DSC back on. The DSC OFF indicator
light will go out.
NOTE
lWhen DSC is on and you attempt to
free the vehicle when it is stuck, or
drive it out of freshly fallen snow,
the TCS (part of the DSC system)
will activate. Depressing the
accelerator will not increase engine
power and freeing the vehicle may
be difficult.
When this happens, turn off the TCS/
DSC.
lIf the TCS/DSC is off when the
engine is turned off, it automatically
activates when the ignition switch is
turned on.
lLeaving the TCS/DSC on will
provide the best stability.
Tire Pressure Monitoring
System
í
The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low in one or more
tires, the system will inform the driver via
the warning light in the instrument panel
and by the warning beep sound.
The tire pressure sensors installed on each
wheel send tire pressure data by radio
signal to the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low
due to seasonal changes, tire
temperatures are also lower. If the tire
temperature lowers, the air pressure
lowers as well, and the TPMS warning
light illuminates more frequently.
Inspect the tire pressure dailybefore
driving, and check the tire pressures
monthly with a tire pressure gauge.
When checking the tire pressures, use
of a digital tire pressure gauge is
recommended.

Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-8).
CAUTION
When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.
NOTE
lPerform tire pressure adjustment
when the tires are cold. Tire pressure
will vary according to the tire
temperature, therefore let the vehicle
stand for 1 hour or only drive it
1.6 km (1 mile) or less before
adjusting the tire pressures. When
pressure is adjusted on hot tires to
the cold inflation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops
below specification.
Also, an illuminated TPMS warning
light, resulting from the tire air
pressure dropping due to cold
ambient temperature, may go out if
the ambient temperature rises. In this
case, it will also be necessary to
adjust the tire air pressures. If the
TPMS warning light illuminates due
to a drop in tire air pressure, make
sure to check and adjust the tire air
pressures.
NOTE
lAfter adjusting the tire air pressures,
it may require some time for the
TPMS warning light to go out. If the
TPMS warning light remains
illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph)
for 10 minutes, and then verify that it
goes out.
lTires can loose a little air quite
naturally over time and the TPMS
cannot tell if the tires are getting too
soft over time or you have a flat.
However, when you find one low tire
in a set of four - that is an indication
of trouble; you should have someone
drive the vehicle slowly forward so
you can inspect any low tire for cuts
and any metal sticking through tread
or sidewall. Put a few drops of water
in the valve stem to see if it bubbles
indicating a bad valve. Leaks need to
be addressed by more than simply
refilling the trouble tire as leaks are
dangerous - take it to an Authorized
Mazda Dealer which has all the
equipment to fix tires, TPMS
systems and order the best
replacement tire for your vehicle.
If the warning light illuminates again even
after the tire pressures are adjusted, there
may be a tire puncture. Replace the
punctured tire with the temporary spare
tire (page 7-7).
NOTE
A tire pressure sensor is not installed to
the temporary spare tire. The warning
light will flash continuously while the
temporary spare tire is being used.

Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
qSystem 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:
lWhen there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
lWhen a large metallic object (e.g. a
large electric household appliance or a
desk-top computer) is placed on the
right side of the rear seat, which may
block radio signals from the tire
pressure sensor to the receiver unit.
lWhen using the following devices in
the vehicle that may cause radio
interference with the receiver unit.
lA digital device such as a personal
computer.
lA current converter device such as a
DC-AC converter.
lWhen excess snow or ice adheres to
the vehicle, especially around the
wheels.
lWhen the tire pressure sensor batteries
are exhausted.
lWhen using a wheel with no tire
pressure sensor installed.
lWhen using tires with steel wire
reinforcement in the side walls.
lWhen using tire chains.
qTires and Wheels
CAUTION
When inspecting or adjusting the tire air
pressures, do not apply excessive force
to the stem part of the wheel unit. The
stem part could be damaged.
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure sensor's
unique ID signal code whenever tires or
wheels are changed, such as changing to
and from winter tires.
NOTE
Each tire pressure sensor has a unique
ID signal code. The signal code must be
registered with the TPMS before it can
work. The easiest way to do it is to have
an Authorized Mazda Dealer change
your tire and complete ID signal code
registration.
When having tires changed at an
Authorized Mazda Dealer
Tire pressure sensor ID signal code
registration is completed when an
Authorized Mazda Dealer changes your
vehicle's tires.
