Essential Safety Equipment
SRS Air Bags
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 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 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:

Constant Monitoring
The following components of the air bag systems are monitored by a diagn\
ostic system:
 y Crash sensors, and diagnostic module (SAS unit) y Front air bag sensors y Air bag modules y Side crash sensors y Air bag/Front seat belt pretensioner system warning light y Front seat belt pretensioners y Related wiring
(With Front Passenger Occupant Classifi cation System)
 y  Front passenger air bag deactivation indicator light y Front passenger seat weight sensors y Front passenger seat weight sensor control module y Front passenger seat belt buckle switches
The diagnostic module continuously monitors the system's readiness. This begins when the
ignition is switched ON and continues while the vehicle is being driven.\

Fuel and Emission
Fuel and Engine Exhaust Precautions
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 min\
imum.
This vehicle 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 stat\
ion pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the emiss\
ion control system
to lose effectiveness. It could also cause engine knocking and serious engine dama\
ge.

*1 The light turns on when the ignition is switched on for an operation che\
ck, and turns off a few seconds later or when the engine is started. If the light does not turn on or remains tur\
ned on, have the vehicle inspected at an
Authorized Mazda Dealer.
Wrench Indicator Light
When the ignition is switched ON, the
wrench indicator light is illuminated and
then turns off after a few seconds.
The wrench indicator light is illuminated
when the preset maintenance period
arrives. Verify the content and perform
maintenance.
Refer to Maintenance Monitor on page
6-20 .
Low Engine Coolant Temperature Indicator Light (Blue)
The light illuminates continuously when
the engine coolant temperature is low and
turns off after the engine is warm.
If the low engine coolant temperature
indicator light remains illuminated after
the engine has been suffi ciently warmed
up, the temperature sensor could have
a malfunction. Consult an Authorized
Mazda Dealer.

sensor senses the surrounding lightness or darkness and automatically tu\
rns the headlights,
other exterior lights and dashboard illumination on or off (see chart above).

Auto-wiper control
When the wiper lever is in the
position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically (off—
intermittent—low speed—high speed).
The sensitivity of the rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch downward for higher sensitivity
(faster response) or rotate it upward for
less sensitivity (slower response).

Tire Pressure Monitoring System
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent fr\
om the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-64 .
The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-17 .
