Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-41)
carefully.
Front Passenger Occupant Classification Sensor
Your vehicle is equipped with a front passenger occupant classification 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 b\
ags and seat belt
pretensioner system from deploying if the front passenger air bag deacti\
vation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the front passen\
ger air bag,
the system deactivates the front passenger front and side air bags and a\
lso the seat belt
pretensioner system when the front passenger air bag deactivation indica\
tor 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 flashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a p\
ossible malfunction.
If this happens, the front passenger front and side air bags and seat be\
lt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light turns on to remind you that the front passenger fro\
nt and side air bags
and seat belt pretensioner will not deploy during a collision.
If the front passenger occupant classification sensor is normal, the indicator light turns
on when the ignition is switched ON. The light turns off after a few seconds. Then, the
indicator light turns on or is off under the following conditions:

WARNING
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 detect the occupant correctly is dangerous.
If the front passenger occupant classification 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 (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 classification 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 figure:
 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.

NOTE
 The system requires about 10 seconds to alternate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off. The front passenger air bag deactivation indicator 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 indicator light may turn on for 10 se\
conds if the
electrostatic capacity on the front passenger seat changes. The air bag/fr ont 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 afte\
r 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 turn on, install the chi\
ld-restraint system on
the rear seat and consult an Authorized Mazda Dealer as soon as possible.
 If the front passenger air bag deactivation indicator light turns on when an occu\
pant
is seated directly in the front passenger seat, have the passenger re-adjust their posture
by sitting with their feet on the floor, and then re-fastening the seat belt. If the front
passenger air bag deactivation indicator light remains turned on, move the passenger to
the rear seat. If sitting in the rear seat is not possible, slide the front passenger seat as far
back as possible. Consult an Authorized Mazda Dealer as soon as possible.

CAUTION
Radio equipment like this is governed
by laws in the United States.
Changes or modifications not expressly
approved by the party responsible
for compliance could void the user's
authority to operate the equipment.
NOTE
 The keyless entry system operation may
vary due to local conditions. The keyless entry system is fully
operational (door/liftgate/trunk lid lock/
unlock) when the ignition is switched
off. The system does not operate if the
ignition is switched to any position
other than off.
 If the key does not operate when
pressing a button or the operational
range becomes too small, the battery
may be weak. To install a new battery,
refer to Key Battery Replacement (page
6-38). Battery life is about one year. Replace
the battery with a new one if the KEY
indicator light (green) flashes in the
instrument cluster. Replacing the battery
about once a year is recommended
because the KEY warning light/
indicator light may not illuminate or
flash depending on the rate of battery
depletion.
 Additional keys can be obtained at
an Authorized Mazda Dealer. Up to
6 keys can be used with the keyless
functions per vehicle. Bring all keys
to an Authorized Mazda Dealer when
additional keys are required.
