Before Driving
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) will negatively affect the emission control
system performance and 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.

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.

N O T E
 


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, traf¿ 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 4-19 .



y The sensitivity of the AUTO lights may be changed by an Authorized Mazda Dealer.

When Driving
Switches and Controls
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 upward for higher sensitivity
(faster response) or rotate it downward for
less sensitivity (slower response).

CAUTION
 


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

 


¾ When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 


¾ If the windshield above the rain
sensor is touched or wiped with a
cloth.
 


¾ If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
  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 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 most likely
that the engine is left running) this is
particularly important when clearing ice
and snow.

Switches and Controls
N O T E
 


y Switching the auto-wiper lever from the

to the position while driving
activates the windshield wipers once,
after which they operate according to
the rainfall amount.
 


y The auto-wiper control may not operate
when the rain sensor temperature is
about -10 °C (14 °F) or lower, or about
85 °C (185 °F) or higher.
 


y If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.
 


y If dirt or foreign matter (such as ice or
matter containing salt water) adheres
to the windshield above the rain sensor,
or if the windshield is iced, it could
cause the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the auto-
wiper control will stop operation. In
this case, set the wiper lever to the low
speed position or high speed position
for manual operation, or remove the ice,
dirt or foreign matter by hand to restore
the auto-wiper operation.
 


y If the auto-wiper lever is left in the
position, the wipers could operate
automatically from the effect of strong
light sources, electromagnetic waves, or
infrared light because the rain sensor
uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the
position other
than when driving the vehicle under
rainy conditions.
 


y If the headlight switch and the
windshield wiper switch are in
,
and the wipers are operated at low or
high speed by the auto wiper control for
several seconds, bad weather conditions
are determined and the headlights may
be turned on.
 


y The auto-wiper control functions can
be turned off. Refer to Personalization
Features on page 9-10 .

Windshield Washer
Pull the lever toward you and hold it to
spray washer À uid.


Washer OFF

N O T E
If the windshield washer is turned on when
the windshield wipers are not operating,
the windshield wipers operate a few times.

If the washer does not work, inspect the
À uid level (page 6-32 ). If the À uid level
is normal, consult an Authorized Mazda
Dealer.
