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.

To achieve maximum engine performance, use the specified fuel.
Fuel
Octane Rating*1 (Anti-knock index)
Regular unleaded fuel 87 [(R+M)/2 method] or above (91 RON or above)
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
Fuel with a rating lower than 87 octane (91 R ON) will negatively affect the emission control
system performance and could also cause engine knocking and serious 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 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 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.
Gasohol containing more than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

CAUTION
If the engine coolant temperature gauge
needle is in the red range, there is the
possibility of overheating. Drive slowly to
reduce engine load until you can find a safe
place to stop the vehicle and wait for the
engine to cool down.
Refer to Overheating on page 7-23.
NOTE
If the engine coolant temperature is high
or the engine is hot, the engine output
may be limited.
▼Fuel Gauge
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.

Full
1/4 Full
Empty
If the low fuel warning light illuminates or
the fuel level is very low, refuel as soon as
possible.
If inconsistency in engine performance or
stalling occurs due to low fuel level
conditions, refuel the vehicle as soon as
possible and add at least 10 L (2.7 US gal,
2.2 Imp gal) of fuel.
Refer to Taking Action on page 7-37.
NOTE
After refueling, it may require some time
for the indicator to
stabilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.
The direction of the arrow () indicates
that the fuel-filler lid is on the left side
of the vehicle.
▼ Dashboard Illumination
When the lights are tu
rned 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 lights are turned on in the
daytime, the dashboard illumination does
not dim.
NOTE
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 dimming may cancel after
the brightness is detected.
When the lights are turned on, the
lights-on indicator light in the
instrument cluster turns on.

Active Driving Display*
Optical receiverDust-proof sheet
WA R N I N G
Always adjust the display brightness and position with the vehicle stopped:
Adjusting the display brightness and position while driving the vehicle is dangerous as doing
so could distract your attention from the road ahead and lead to an accident.
CAUTION
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.
 Do not place objects above the active driving display or apply stickers to the dust-proof
sheet/optical receiver as they will cause interference.
 A sensor is integrated to control the display' s luminosity. If the optical receiver is covered,
the display's luminosity will lower ma king the display difficult to view.
 Do not allow intense light to hit the optical receiver. Otherwise, it could cause damage.
NOTE
Wearing polarized sunglasses will reduce the visi bility of the active driving display due to
the characteristics of the display.
If the battery has been removed and re-installed or the battery voltage is low, the adjusted
position may deviate.
The display may be difficult to view or temporarily affected by weather conditions such as
rain, snow, light, and temperature.
If the audio system is removed, the active driving display cannot be operated.
The active driving display indica tes the following information:

Shift-Lock System
The shift-lock system prevents shifting out
of P unless the brake pedal is depressed.

To shift from P:
1. Depress and hold the brake pedal.
2. Start the engine.
3. Press and hold the lock-release button.
4. Move the selector lever.
NOTE
When the ignition is switched to ACC or
the ignition is switched off, the selector
lever cannot be shifted from P position.
The ignition cannot be switched to OFF
if the selector lever is not in P position.
▼ Shift-Lock Override
If the selector lever will not move from P
using the proper shift procedure, continue
to hold down the brake pedal.
1. Remove the shift-lock override cover
using a cloth-wr apped flat head
screwdriver.
2. Insert a screwdriver and push it down.

3. Press and hold the lock-release button.
4. Move the selector lever.
Take the vehicle to an Authorized Mazda
Dealer to have the system checked.
Transaxle Ranges
The shift position indication in the
instrument cluster illuminates.
Refer to Indication/Indicator Lights on
page 4-25, 4-40, 4-53.
The selector lever must be in P or N
position to operate the starter.
P (Park)
WA R N I N G
Always set the selector lever to P position
and set the parking brake:
Only setting the selector lever to the P
position without using the parking brake to
hold the vehicle is dangerous. If P fails to
hold, the vehicle could move and cause an
accident.
CAUTION
 Shifting into P, N or R while the vehicle is
moving can damage your transaxle.
 Shifting into a driving gear or reverse
when the engine is running faster than
idle can damage the transaxle.
R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete stop
before shifting to or from R, except under
rare circumstances as explained in
Rocking the Vehicle (page 3-51).

When the selector lever is shifted to the R
position with the ignition switched ON, the
parking sensor system is activated and a
beep sound is heard.
Refer to Parking Sensor System on page
4-272.
N (Neutral)
WARNING
If the engine is running faster than idle, do
not shift from N or P into a driving gear:
It's dangerous to shift from N or P into a
driving gear when the engine is running
faster than idle. If this is done, the vehicle
could move suddenly, causing an accident
or serious injury.
Do not shift into N when driving the
vehicle:
Shifting into N while driving is dangerous.
Engine braking cannot be applied when
decelerating which could lead to an
accident or serious injury.
CAUTION
Do not shift into N when driving the
vehicle. Doing so can cause transaxle
damage.
NOTE
Apply the parking brake or depress the
brake pedal before moving the selector
lever from N position to prevent the
vehicle from moving unexpectedly.
D (Drive)
D is the normal driving position. From a
stop, the transaxle will automatically shift
through a 6-gear sequence.
M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the selector lever. Refer to
Manual Shift Mode on page 4-62.
