First, please read“Supplemental Restraint System (SRS) Precautions ”(page 2-29)
carefully.
q Driver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position sensor as a part of the
supplemental restraint system. The sensor is located under the driver seat. The sensor
determines whether the driver seat is fore or aft of a reference position and sends the seat
position to the diagnostic module (SAS unit). The SAS unit is designed to control the
deployment of the driver air bag depending on how close the driver seat is to the steering
wheel.
The air bag/seat belt pretensioner system warning light flashes if the sensor has a possible
malfunction (page 2-36).
qPassenger Seat Weight Sensors
Your vehicle is equipped with a passenger seat weight sensors as a part of the supplemental
restraint system. These sensors are located under both of the passenger seat rails. These
sensors determine the total seated weight on the passenger seat. The SAS unit is designed
to prevent the passenger front and side air bags and seat belt pretensioner system from
deploying if the total seated weight is less than approximately 30 kg (66 lbs).
To reduce the chance of injuries caused by deployment of the passenger air bag, the system
deactivates the passenger front and side air bags and also the seat belt pretensioner system
when:
lThere is no passenger in the passenger seat. (The passenger air bag deactivation
indicator light does not illuminate.)
lThe total seated weight on the passenger seat is less than approximately 30 kg (66 lbs).
(The passenger air bag deactivation indicator light illuminates.)
This system shuts off the passenger front and side air bags and seat belt pretensioner
system, so make sure the passenger air bag deactivation indicator light illuminates
according to the following table.
The air bag/seat belt pretensioner system warning light flashes and the passenger air bag
deactivation indicator light illuminates if the sensors have a possible malfunction. If this
happens, the passenger front and side air bags and seat belt pretensioner system will not
deploy.

WARNING
Do not decrease the total seated weight on the passenger seat:When an adult or large child sits on the passenger seat, decreasing the total seated
weight on the passenger seat from the total seated weight of approximately 42 kg
(93 lbs) required for air bag deployment is dangerous. The passenger seat weight
sensors will detect the reduced total seated weight condition and the passenger front
and side air bags and seat belt pretensioner system will not deploy during an
accident. The passenger will not have the supplementary protection of the air bag,
which could result in serious injury. Decreasing the total seated weight on the
passenger seat from the total seated weight of approximately 42 kg (93 lbs) could
result in an air bag not deploying under the following conditions, for example:
ØLuggage or other items placed under the passenger seat or between the passenger
seat and center console that push up the passenger seat bottom.
Ø The passenger seat occupant sits in a manner such that the occupant's entire
weight is not placed on the seat sitting too close to the door.
Ø Any accessories which might decrease the total seated weight on the passenger
seat are attached to the passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the passenger seat is close to 30 kg (66 lbs)
and they will reactivate before the weight exceeds 42 kg (93 lbs).

Do not increase the total seated weight on the passenger seat:When an infant or small child sits on the passenger seat, increasing the total seated
weight on the passenger seat from the total seated weight of approximately 30 kg
(66 lbs) is dangerous. The passenger seat weight sensors will detect the increased
total seated weight, which could result in the unexpected deployment of the
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 passenger
seat beyond the total seated weight of approximately 30 kg (66 lbs) could result in
the passenger front and side air bags and seat belt pretensioner system deployment
in an accident under the following conditions, for example:
ØThe total seated weight of the child with the child-restraint system on the
passenger seat is approximately 30 kg (66 lbs) or more.
Ø Luggage or other items are placed on the seat with the child in the child-restraint
system.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The passenger seat is moved backward, and it is pushed into luggage or other
items placed behind it.
Ø Luggage or other items are placed between the passenger seat and center
console.
Ø Any accessories which might increase the total seated weight on the passenger
seat are attached to the passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the passenger seat is close to 30 kg (66 lbs)
and they will reactivate before the weight exceeds 42 kg (93 lbs).
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the seat bottoms:
ØDo not place sharp objects on the seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the seats or under the seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf you place your child on the passenger seat, secure the child-restraint system
properly and slide the passenger seat as far back as possible.

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 seats, 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.
FuelOctane 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.
You may use a regular unleaded fuel with an Octane Rating from 87 to 90 (91 to 95 RON)
but this will slightly reduce performance, such as reduced engine output, and engine
knocking.
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
Ø USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead
to deterioration of the emission control system and or failures.
Ø Your 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.
Ø Never 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.
