First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-48 )
carefully.
Front Passenger Occupant Classifi cation Sensor
Your vehicle is equipped with a front passenger occupant classifi cation sensor as a part
of the supplemental restraint system. This sensor is equipped in the front passenger's seat
cushion. This sensor measures the electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front passenger front and side air bags and seat belt
pretensioner system from deploying if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the front passenger air bag,
the system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivation indicator light turns
on. Refer to the following table for the front passenger air bag deactivation indicator light
illumination conditions.

This system shuts off the front passenger front and side air bags and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light turns on
according to the following table.

The air bag/front seat belt pretensioner system warning light fl ashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction.
If this happens, the front passenger front and side air bags and seat belt pretensioner system
will not deploy.

WARNING
Do not allow an occupant in the front passenger's seat to sit with a posture which
makes it diffi cult for the front passenger occupant classifi cation sensor to detect the
occupant correctly:
Sitting in the front passenger's seat with a posture which makes it diffi cult for the front
passenger occupant classifi cation sensor to detect the occupant correctly is dangerous.
If the front passenger occupant classifi cation sensor cannot detect the occupant sitting
on the front passenger's seat correctly, the front passenger 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 supplementary 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 passenger occupant classifi cation sensor
cannot detect a passenger sitting on the front passenger's seat correctly and the
deployment/non-deployment of the air bags cannot be controlled as indicated in the
front passenger air bag deactivation indicator light on/off condition chart. For example:




 A front passenger is seated as shown in the following fi gure:

 

 A rear passenger pushes up on the front passenger seat with their feet.



 Luggage or other items placed under the front passenger seat or between the front
passenger seat and driver seat that push up the front passenger seat bottom.

Before Driving
Doors and Locks
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 moves 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 operates when the liftgate
is closed manually.
WARNING
When closing a liftgate, always keep
hands and fi ngers away from the
liftgate:
Placing hands or fi ngers around a
liftgate is dangerous because the
liftgate closes automatically from the
near-shut position, which could cause
hands and fi ngers 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 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
 


 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.
 


 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.
 


 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.
 


 Gasohol containing more than 10 % ethanol.

