WA R N I N G
Do not allow an occupant in the passenger's seat to sit with a posture which makes it difficult
for the passenger occupant classification sensor to detect the occupant correctly:
Sitting in the passenger's seat with a posture which makes it difficult for the passenger
occupant classification sensor to detect the occupant correctly is dangerous. If the passenger
occupant classification sensor cannot detect the occupant sitting on the passenger's seat
correctly, the passenger front and side air bags and pretensioner system may not operate
(non-deploy) or they may operate (deploy) accidentally. The passenger will not have the
supplementary protection of the air bags or the accidental operation (deployment) of the air
bags could result in serious injury or death.
Under the following conditions, the passenger occupant classification sensor cannot detect a
passenger sitting on the passenger's seat co rrectly and the deployment/non-deployment of
the air bags cannot be controlled as indicated in the passenger air bag deactivation indicator
light on/off condition chart. For example:
 A passenger is seated as shown in the following figure:

Luggage or other items placed under the passe nger seat or between the passenger seat and
driver seat that push up the passenger seat bottom.
 An object, such as a seat cushion, is put on the passenger's seat or between the passenger's
back and the seatback.
 A seat cover is put on the passenger's seat.
 Luggage or other items are placed on the seat with the child in the child-restraint system.
 The seat is washed.
 Liquids are spilled on the seat.
 The passenger seat is moved backward, pushing into luggage or other items placed behind
it.
 Luggage or other items are placed between the passenger seat and driver seat.
 An electric device is put on the passenger's seat.
 An additional electrical device, such as a seat warmer is installed to the surface of the
passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will deactivate if the
passenger air bag deactivation indicator light turns on.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the seat cushion:
 Do not place sharp objects on the seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the seats or under the seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the seats as far back as possible an d always sit upright against the seatbacks with
seat belts worn properly.
 If you place your child on the passenger seat , secure the child-restraint system properly
and slide the passenger seat as far back as possible.

Constant Monitoring
The following components of the air bag systems are monitored by a diagnostic system:

Front air bag sensors
Crash sensors, and diagnostic module (SAS unit)
Side crash sensors
Air bag modules
Seat belt pretensioners
Air bag/Seat belt pretensioner system warning light
Related wiring
Passenger occupant classification sensor
Passenger occupant classification module
Passenger air bag deactivation indicator light

The diagnostic module continuously monitors the system's readin ess. This begins when the
ignition is switched ON and contin ues while the vehicle is being driven.

Fuel and Engine Exhaust Precautions
▼Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use O
NLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

To achieve maximum engine performance, use the specified fuel.
Fuel Octane Rating*1 (Anti-knock index)
Premium unleaded fuel 91 [(R+M)/2 method] or above (96 RON or ab ove)
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
Regular unleaded fuel with an octane rating from 87 to 90 (91 t o 95 RON) can be used, but
this will reduce perform ance slightly, such as reduced engine o utput, and engine knocking.
Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission control
system performance and could also cause engine knocking and ser ious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the 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 other than a Mazda genuine product, otherwise the
emission control system could be damaged. Consult an Authorized Mazda Dealer for
details.
Gasoline blended with oxygenates such as alcohol or ether compo unds 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 conta ining alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability pr oblems resulting from the use of the following may not be
covered by the warranty.
Gasohol containing more than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

▼ Dashboard Illumination
(Without auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dashboard illumination is
dimmed.
(With auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dashboard illumination is
dimmed. However, when the light sensor
detects that the surrounding area is bright
such as when the position lights are turned
on in the daytime, the dashboard
illumination does not dim.
NOTE
(With auto-lig
ht control)
When the ignition is switched ON in the
early evening or at dusk, the dashboard
illumination is dimmed for several
seconds until the light sensor detects the
brightness of the surrounding area,
however, the dimmer may cancel after
the brightness is detected.
When the position lights are turned on,
the position lights indicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-45.
The brightness of the instrument cluster
and dashboard illuminations can be
adjusted by rotating the knob.
The brightness decreases by rotating the
knob to the left. A beep sound will be
heard when the knob has been rotated to
the maximum dim position.
The brightness increases by rotating the
knob to the right.
Dim

Function for cancelling illumination
dimmer
The illumination dimmer can be canceled
by rotating the dashboard illumination
knob to the right until a beep sound is
heard while the instrument cluster is
dimmed with the ignition switched ON. If
the instrument cluster's visibility is
reduced due to glare from surrounding
brightness, cancel the illumination
dimmer.
NOTE
When the illumination dimmer is
canceled, the instrument cluster cannot
be dimmed even if the position lights are
turned on.
When the illumination dimmer is
canceled, the screen in the center
display switches to constant display of
the daytime screen.
