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 minimum.
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 station pumps.
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
 


¾ 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.
 


¾ 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.
 


¾ Never add fuel system additives, otherwise the emission control system could be damaged.
Consult an Authorized Mazda Dealer for details.
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 warranty.
 


y Gasohol containing more than 10 % ethanol.



y Gasoline or gasohol containing methanol.



y Leaded fuel or leaded gasohol.

WARNING
Adjust the brightness or the display position while paying attention to safe driving:
If you do not pay attention to your driving while trying to make the adjustments, it could
lead to an unexpected accident.
CAUTION
 


¾ Do not try to adjust the angle or open/close the active driving display manually.
Fingerprints on the display will make it diffi cult to view and using excessive force when
operating it could cause damage.
 


¾ Do not place objects in the vicinity of the active driving display. The active driving display
may not operate or any interference with its operation could cause damage.
 


¾ Do not place beverages near the active driving display. If water or other liquids are
splashed on the active driving display, it could cause damage.
 


¾ Do not place objects above the active driving display screen or apply stickers to the
combiner as they will cause interference.
 


¾ A sensor is integrated to control the display's luminosity. If the optical receiver is covered,
the display's luminosity will lower making the display diffi cult to view.




¾ Do not allow intense light to hit the optical receiver. Otherwise, it could cause damage.
NOTE




y It may be diffi cult to view the display when wearing sunglasses. Take off your sunglasses
or adjust the luminosity.
 


y If the battery has been removed and re-installed or the battery voltage is low, the adjusted
position may deviate.
 


y The display may be diffi cult to view or temporarily affected by weather conditions such
as rain, snow, light, and temperature.
 


y If the audio system is removed, the active driving display cannot be operated.

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.

Switches and Controls
CAUTION
 


¾ Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 




¾ The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wiper lever is in the
position and the
ignition is switched ON as fi ngers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
 


y The headlights, other exterior lights and dashboard illumination may not turn off
immediately even if the surrounding area becomes well-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffi c jams inside tunnels, or in indoor parking lots.

 In this case, the lights turn off if the light switch is turned to the position.



y(Without auto headlight off function)
 When the headlight switch is in the position and the ignition is switched to ACC or
the ignition is switched off, the headlights, other exterior lights and dashboard
illumination will turn off.
 


y The dashboard illumination can be adjusted by rotating the knob in the instrument
cluster. Also, the day/night mode can be changed by rotating the knob until a beep sound
is heard. To adjust the brightness of the dashboard illumination:
Refer to Dashboard Illumination on page 4-16 .
 

y The sensitivity of the AUTO lights may be changed by an Authorized Mazda Dealer.
Refer to Personalization Features on page 9-12 .
