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.

This vehicle will perform best w ith 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 gaso
line station pumps.
Fuel with a rating lower than 87 octane (91 RON) will negativel y 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 us ing gasohol of any kind if your vehicle engine
is performing poorly.
 Never add fuel system additive s, 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 problems resulting from the use of the following may not be
covered by the warranty.
•Gasohol containing mo re than 10 % ethanol.
•Gasoline or gasohol containing methanol.
•Leaded fuel or leaded gasohol.

•During normal driving, the engine
coolant temperature stabilizes at 100 °C
(210 °F) or less, and the gauge indicates
a range lower than 100 °C (210 °F).
•If the engine load increases and the
engine coolant temperature exceeds
100 °C (210 °F), the gauge indicates the
engine coolant temperature.
▼Fuel Gauge (Without
Multi-information Display)
The fuel gauge shows approximately how
much fuel is remaining in the tank when
the ignition is
switched ON. We
recommend keeping the tank over 1/4 full.

If the low fuel warnin g light illuminates or
the fuel level is very low, refuel as soon as
possible.
Refer to Taking Action on page 7-38 .
NOTE
•After refueling, it may require some time
for the indicator to st abilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.
•The display indicating a quarter or less
remaining fuel has more segments to
show the remaining fu el level in greater
detail.
•The direction of the arrow () indicates
that the fuel-filler lid is on the left side

CAUTION
Do not shade the light sensor by adhering a st icker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 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 fingers could be pinche d or the wipers and wiper blades could be
damaged when the wipers activa te automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is partic
ularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
•The headlights and other exterior lights 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 minute s such as inside long
tunnels, traffic jams inside tunn els, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the
position.
•If the headlight switch and the windshield wiper switch are in , and the wipers are
operated at low or high speed by the auto wi per control for several seconds, bad weather
conditions are determined and the headlights may be turned on.
•The sensitivity of the auto-light control may be changed.

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
Do not shade the rain sensor by adhering
a sticker or a label on the windshield.
Otherwise the rain sensor will not
operate correctly.
When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched or wiped with a cloth.
 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 fingers 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.

NOTE
•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.
•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.
•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.
•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 wi ll 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.
•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.
•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.
•The auto-wiper control functions can be
turned off. Refer to Personalization
Features on page 9-11.
