Front passenger seat weight sensors
Your vehicle is equipped with front passenger seat weight sensors as a part of the
supplemental restraint system. These sensors are located under both of the front passenger
seat rails. These sensors determine the total seated weight on the front passenger seat. The
sensors are also designed to prevent the front passenger air bag from inflating if the total
seated weight is less than approximately 30 kg (66 lb).
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when:
•There is no passenger in the front passenger seat. (The front passenger air bag
deactivation indicator light does not illuminate.)
•The total seated weight on the front passenger seat is less than approximately 30 kg (66
lb). (The front passenger air bag deactivation indicator light illuminates.)
This system shuts off the front passenger front and side air bags and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light illuminates
according to the chart below.
The air bag/front seat belt pretensioner system warning light flashes and the front
passenger air bag deactivation indicator light illuminates if the sensors have a possible
malfunction. If this happens, the front passenger front and side air bags and seat belt
pretensioner system will not deploy.
Front passenger air bag deactivation indicator light
This indicator light illuminates to remind you that the front passenger front and side air
bags and seat belt pretensioner will not deploy during a collision.
If the front passenger weight sensors are normal, the indicator light illuminates when the
ignition switch is turned to the ON position. After about 6 seconds it goes out.

Decreasing the Total Seated Weight on the Front Passenger Seat:
When an adult or large child sits on the front passenger seat, decreasing the total
seated weight on the front passenger seat from the total seated weight of
approximately 42 kg (93 lb) required for air bag deployment is dangerous. The front
passenger seat weight sensors will detect the reduced total seated weight condition and
the front passenger front and side air bags and seat belt pretensioner system will not
deploy during an accident. The front passenger will not have the supplementary
protection of the air bag, which could result in serious injury. Decreasing the total
seated weight on the front passenger seat from the total seated weight of
approximately 42 kg (93 lb) could result in an air bag not deploying under the
following conditions, for example:
•A rear passenger pushes up on the front passenger seat with the feet.
•Luggage or other items placed under the front passenger seat or between the front
passenger seat and front passenger seat side table that push up the front passenger
seat bottom.
•The front passenger seat occupant sits in a manner that does not place the entire
weight of the occupant on the seat such as by sitting too close to the door, grasping
the assist grip or the rim of the sunroof.
•The front passenger seatback contacts the second-row seat.
•Any accessories such as decreasing the total seated weight on the front passenger
seat are attached to the front passenger seat.

Increasing 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 serious injury. Increasing the total seated weight on the
front passenger seat from 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:
•Luggage or other items are placed on the seat with the child in the child-restraint
system.
•A rear passenger or luggage push or pull down on the front passenger seatback.
•A rear passenger steps on the front passenger seat rails with the feet.
•Luggage or other items are placed on the seatback or hung on the assist grip, head
restraint or armrest.
•The seat is washed.
•Liquids are spilled on the seat.
•The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
•The front passenger seatback contacts the second-row seat.
•Luggage or other items are placed between the front passenger seat and front
passenger seat side table.
•Any accessories such as increasing the total seated weight on the front passenger
seat are attached to the front passenger seat.
•To assure proper deployment of the front air bag and to prevent damage to the sensors
in the front seat bottoms:
Do not place sharp objects on the front seat bottoms or leave heavy luggage on them.
Do not spill any liquids on the front seats or under the front seats.
•To allow the sensors to function properly, always perform the following:
Adjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
If you place your child on the front passenger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-51).

Driver and front passenger buckle switches
The buckle switches on the front seat belts detect whether or not the front seat belts are
securely fastened and further control the deployment of the air bags on the front seats.

How the Side Air Bags Work*
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 air bags and after the inflation, the side air bags
quickly deflate.
The side air bags will function only once. After that, the side air bags will not work again
and must be replaced.
Only an Authorized Mazda Dealer can replace the systems.
NOTE
•The system requires about 10 seconds to alternate between turning the front
passenger front and side air bags and seat belt pretensioner system on or off.
•The front passenger air bag deactivation indicator light may illuminate repeatedly if
luggage or other items are put on the front passenger seat, or if the temperature of the
vehicle’s interior changes suddenly.
•The front passenger air bag deactivation indicator light may illuminate for 10 seconds
if the total seated weight on the front passenger seat changes.
•If the front passenger air bag deactivation indicator light does not illuminate after
installing a child-restraint system on the front passenger seat, install the child-
restraint system on the rear seat and consult an Authorized Mazda Dealer as soon as
possible.
To prevent damage to the side air bag wiring, don’t place luggage or other objects under
the front seats.
The side air bag will deploy
only on the side the vehicle receives
the force of the impact.

Damaged Air Bag System
Components:
Driving with damaged air bag system
components is dangerous. A collision,
even one not strong enough to inflate
the air bags, could damage the system
components. If there was a
subsequent collision, a damaged
component would not inflate the air
bags. Always have an Authorized
Mazda Dealer inspect the air bag
systems after a collision.
Removing Interior Parts:
Removing any components such as
the front seats (if side air bags are
equipped), front dashboard, the
steering wheel or parts 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.
Air Bag Disposal:
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.

Before Driving Your Mazda
Form No. 8S06-EA-03H
Fuel and Engine Exhaust Precautions
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.
*U.S. federal law requires that octane ratings be posted on gasoline station pumps.
Ecuador, Venezuela
Use only premium unleaded fuel:91 [ (R+M)/2 method] or above (96 RON or above)
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.
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.
•Gasohol containing more than 10% ethanol.
•Gasoline or gasohol containing methanol.
•Leaded fuel or leaded gasohol.
Fuel Requirements
Fuel Octane Rating* (Anti-knock index)
Regular unleaded fuel 87 [ (R+M)/2 method] or above (91 RON or above)
•USE 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.
•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.
•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.
