WARNING
Do not increase the total seated weight on the front passenger seat:
When an infant or small child sits on the front passenger seat, increasing the total
seated weight on the front passenger seat from the total seated weight of
approximately 30 kg (66 lb) is dangerous. The front passenger seat weight sensors will
detect the increased total seated weight, which could result in the unexpected
deployment of the front passenger front and side air bags and seat belt pretensioner
system in an accident and may cause serious injury. Increasing the total seated weight
on the front passenger seat beyond the total seated weight of approximately 30 kg (66
lb) could result in the front passenger front and side air bags and seat belt
pretensioner system deployment in an accident under the following conditions, for
example:
lLuggage or other items are placed on the seat with the child in the child-restraint
system.
lA rear passenger or luggage push or pull down on the front passenger seatback.lA rear passenger steps on the front passenger seat rails with the feet.lLuggage or other items are placed on the seatback or hung on the head restraint.lThe seat is washed.lLiquids are spilled on the seat.lThe front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
lThe front passenger seatback contacts the rear seat.lLuggage or other items are placed between the front passenger seat and driver seat.lAny accessories which might increase the total seated weight on the front passenger
seat are attached to the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the front passenger seat is close to 30 kg (66 lb)
and they will reactivate before the weight exceeds 42 kg (93 lb).

WARNING
Do not operate a vehicle with damaged air bag/seat belt pretensioner system
components:
Expended or damaged air bag/seat belt pretensioner system components must be
replaced after any collision which caused them to deploy or damage them. Only a
trained Authorized Mazda Dealer can fully evaluate these systems to see that they will
work in any subsequent accident. Driving with an expended or damaged air bag or
pretensioner unit will not afford you the necessary protection in the event of any
subsequent accident which could result in serious injury or death.
Do not remove interior air bag parts:
Removing any components such as the front seats, front dashboard, the steering wheel
or parts on the front and rear window pillars and along the roof edge, containing air
bag parts or sensors is dangerous. These parts contain essential air bag components.
The air bag could accidentally activate and cause serious injuries. Always have an
Authorized Mazda Dealer remove these parts.
Dispose of the air bag properly:
Improper disposal of an air bag or a vehicle with live air bags in it can be extremely
dangerous. Unless all safety procedures are followed, injury can result. Ask an
Authorized Mazda Dealer how to safely dispose of an air bag or how to scrap an air
bag equipped vehicle.
NOTE

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.
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 and deteriorate shift
quality during its use. Refueling the vehicle with the correct octane fuel a couple of times
will restore vehicle performance and shift quality.
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.
Gasoline blended with oxygenates such as alcohol or ether compounds 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 containing 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 Mazda warranty.
lGasohol containing more than 10% ethanol.
lGasoline or gasohol containing methanol.
lLeaded fuel or leaded gasohol.

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.TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
CAUTION
lEach tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the 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-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces 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 tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.

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.
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.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 7-6).
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 TPMS 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 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 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.When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.
1. After tires have been changed, turn the
ignition switch to the ON position, then
turn it back to the ACC or LOCK
position.
2. Wait for about 15 minutes.
3. After about 15 minutes, drive the
vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID signal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15
minutes of changing tires, the tire
pressure monitoring system warning
light will flash because the sensor ID
signal code would not have been
registered. If this happens, park the
vehicle for about 15 minutes, after
which the sensor ID signal code will
register upon driving the vehicle for 10
minutes.
