If your vehicle is also equipped with a driver and front passenger occupant
classification system, refer to the Driver and Front Passenger Occupant Classification
System (page 2-56) for details.
If your vehicle is equipped with a driver and front passenger occupant classification
system, the front passenger air bag deactivation indicator light illuminates for a specified
time after the ignition is switched ON.
Small children must be protected by a child-restraint system as stipulated by law in every
state and province. In certain states and provinces, larger children must use a child-restraint
system (page 2-26).
Carefully consider which child-restraint system is necessary for your child and follow the
installation directions in this Owner's Manual as well as the child-restraint system
manufacturer's instructions.
WARNING
Seat belts must be worn in air bag equipped vehicles:Depending only on the air bags for protection during an accident is dangerous.
Alone, air bags may not prevent serious injuries. The appropriate air bags can be
expected to inflate only in the first accident, such as frontal, near frontal, side
collisions that are at least moderate. Vehicle occupants should always wear seat
belts.
Children should not ride in the front passenger seat: Placing a child, 12 years or under, in the front seat is dangerous. The child could be
hit by a deploying air bag and be seriously injured or even killed. Even if the front
passenger air bag deactivation indicator light illuminates, always move the front
passenger seat as far back as possible. A sleeping child is more likely to lean against
the door and be hit by the side air bag in a moderate collision to the front-passenger
side of the vehicle. Whenever possible, always secure a child 12 years and under on
the rear seat with an appropriate child-restraint system for the child's age and size.

Do not increase the total seated weight on the front passenger seat:When an infant or small child sits on the front passenger seat, increasing the total
seated weight on the front passenger seat is dangerous. The front passenger seat
weight sensors will detect the increased total seated weight, which could result in the
unexpected deployment of the front passenger front and side air bags and seat belt
pretensioner system in an accident and may cause serious injury. Increasing the total
seated weight on the front passenger seat could result in the front passenger front
and side air bags and seat belt pretensioner system deployment in an accident under
the following conditions, for example:
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage push or pull down on the front passenger seatback.
Ø A rear passenger steps on the front passenger seat rails with their feet.
Ø Luggage or other items are placed on the seatback or hung on the head restraint.
Ø Heavy items are placed in the seatback map pocket.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
Ø The front passenger seatback contacts the rear seat.
Ø Luggage or other items are placed between the front passenger seat and driver
seat.
Ø Any accessories which might increase the total seated weight on the front
passenger seat are attached to the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the front passenger air bag deactivation indicator light illuminates.
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the front seat bottoms:
ØDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the front seats or under the front seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf 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
2-35).

NOTElThe 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.
lThe front passenger air bag deactivation indicator light may illuminate repeatedly if luggage or
other items are put on the front passenger seat, or if the temperature of the vehicle's interior
changes suddenly.
lThe front passenger air bag deactivation indicator light may illuminate for 10 seconds if the total
seated weight on the front passenger seat changes.
lThe air bag/front seat belt pretensioner system warning light might illuminate if the front
passenger seat receives a severe impact.
lIf the front passenger air bag deactivation indicator light does not illuminate 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 illuminate, install the child-restraint system on the rear
seat and consult an Authorized Mazda Dealer as soon as possible.
lIf the front passenger air bag deactivation indicator light illuminates when an adult is seated 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
still illuminates, 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.
qDriver and Front Passenger Buckle Switches
The buckle switches on the front seat belts detect whether or not the front seat belts are
securely fastened and further control the deployment of the air bags.

WARNING
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the shift lever is
in P (automatic transaxle) or in 1st gear
or R (manual transaxle):Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the shift
lever to P (automatic transaxle) or to
1st gear or R (manual transaxle) is
dangerous. Unexpected vehicle
movement could occur which could
result in an accident.
In addition, if your intention is to
leave the vehicle for even a short
period, it is important to switch the
ignition off, as leaving it in another
position will disable some of the
vehicle's security systems and run the
battery down.
ACC (Accessory)
Some electrical accessories will operate
and the indicator light (ACC) illuminates.
In addition, for vehicles equipped with the
steering column lock function, the
steering wheel unlocks.
NOTE
The advanced keyless entry system does not
function while the push button start has been
pressed to ACC, and the doors will not lock/
unlock even if they have been locked manually.
ON
This is the normal running position after
the engine is started. The indicator light
(ON) turns off. (The indicator light (ON)
illuminates when the ignition is switched

The warning lights (except brakes) should
be inspected before the engine is started
(page 5-41).
NOTE
(With headlight auto-leveling)
When the push button start is pressed to the
ON position, the sound of the headlight
leveling motors operating at the front of the
engine compartment can be heard. This does
not indicate an abnormality.

qLuggage Compartment
WARNING
Do not place anything on top of the

braking or a collision, the cargo
could become a projectile that could
hit and injure someone. The vehicle
has a light weight luggage
compartment cover to keep the
contents of your luggage area out of

that are not tied down in an accident
such as a rollover. Tie down all heavy
objects, whether luggage or cargo,
using the tie down hooks.

secured before driving: Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury.
CAUTION
Make sure the luggage compartment
cover is firmly secured. If it is not
firmly secured, it could unexpectedly
disengage resulting in injury.
