depending on the person's physique.
The curtain air bag is ready for inflating regardless of what the front passenger air bag
deactivation indicator light on/off condition chart indicates.
If the front passenger air bag deactivation indicator light doe s not turn on when the ignition
is switched ON and does not turn on as indicated in the front p assenger air bag deactivation
indicator light on/off condition chart, do not allow an occupan t to sit in the front passenger
seat and consult an Authorized M azda Dealer as soon as possible. The system may not work
properly in an accident.
WA R N I N G
Do not allow an occupant in the front passenger's seat to sit with a posture which makes it
difficult for the front passenger occupant classification sensor to detect the occupant
correctly:
Sitting in the front passenger's seat with a posture which makes it difficult for the front
passenger occupant classification sensor to dete ct the occupant correctly is dangerous. If the
front passenger occupant classification sensor ca nnot detect the occupant sitting on the front
passenger's seat correctly, the front passenge r front and side air bags and pretensioner
system may not operate (non-deploy) or they may operate (deploy) accidentally. The front
passenger will not have the su pplementary protection of the air bags or the accidental
operation (deployment) of the air bags could result in serious injury or death.
Under the following conditions, the front passe nger occupant classification sensor cannot
detect a passenger sitting on the front passe nger's seat correctly and the deployment/
non-deployment of the air bags cannot be contro lled as indicated in the front passenger air
bag deactivation indicator light on /off condition chart. For example:

The front passenger front and side air bags and seat belt pretensioner systems will deactivate
if the front passenger air bag deactivation indicator light turns on.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 Do not place sharp objects on the front seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the front seats or under the front seats.
 To allow the sensors to function properly, always perform the following:
 Adjust the front seats as far back as possibl e and always sit upright against the seatbacks
with seat belts worn properly.
 If you place your child on the front passenger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-44).
NOTE
•The system requires about 10 seconds to alte rnate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off.
•The front passenger air bag deactivation indicato r light may turn on repeatedly if luggage
or other items are put on the front passenger seat, or if the temperature of the vehicle's
interior changes suddenly.
•The front passenger air bag deactivation indicato r light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
•The air bag/front seat belt pretensioner system warning light might turn on if the front
passenger seat receives a severe impact.
•If the front passenger air bag deactivation indicator light does not turn on after installing
a child-restraint system on the front passenger seat, first, re-install your child-restraint
system according to the procedure in this owner's manual. Then, if the front passenger air
bag deactivation indicator light still does not tu rn on, install the child-restraint system on
the rear seat and consult an Authorized Mazda Dealer as soon as possible.
•If the front passenger air bag deactivation i ndicator light turns on when an occupant is
seated directly in the front passenger seat, have the passenger re-adjust their posture by
sitting with their feet on the floor, and th en re-fastening the seat belt. If the front
passenger air bag deactivation i ndicator light remains turned on, move the passenger to
the rear seat. If sitting in the rear seat is no t possible, slide the front passenger seat as far
back as possible. Consult an Authorized Mazda Dealer as soon as possible.

CAUTION
Sensors are installed on both ends of the
power liftgate. Be careful not to allow the
sensors to be scratched or damaged by
sharp objects, otherwise the liftgate may
no longer open/close automatically. In
addition, if the sensor is damaged while the
liftgate is closing automatically, the system
will stop.
Sensor
NOTE
The jam-safe equipment does not activate
during easy closure operation when the
power liftgate is between the near-shut
position and fully closed position.
When the power liftgate is moving in the
open/close direction and an obstruction is
detected, the beep sound will be heard and
the liftgate mo ves in the reverse direction
and stops.
Liftgate easy closure
The Easy Closure system automatically
closes the liftgate completely from the
near-shut position.
This system also opera tes when the liftgate
is closed manually.
WA R N I N G
When closing a liftgate, always keep hands
and fingers away from the liftgate:
Placing hands or fingers around a liftgate is
dangerous because the liftgate closes
automatically from the near-shut position,
which could cause hands and fingers to be
pinched and injured.
NOTE
•If the electric liftgate opener is pressed
while the easy closure function is
operating, the liftgate can be opened.
•If the liftgate is opened/closed
repeatedly in a short period of time, the
easy closure function may not operate.
Wait for about 2 seconds and then try
again.

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.

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
of the vehicle.
▼ Dashboard Illumination
(Without auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dash
board illumination is
dimmed.
(With auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dash board illumination is
dimmed. However, when the light sensor
detects that the surrounding area is bright
such as when the position lights are turned
on in the daytime, the dashboard
illumination does not dim.
NOTE
•(With auto-light control)
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 dimmer may cancel after
the brightness is detected.
