Increasing 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 from the total seated weight of
approximately 30 kg (66 lb) 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 serious injury. Increasing the total seated weight on the
front passenger seat from the total seated weight of approximately 30 kg (66 lb) 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:
•Luggage or other items are placed on the seat with the child in the child-restraint
system.
•A rear passenger or luggage push or pull down on the front passenger seatback.
•A rear passenger steps on the front passenger seat rails with the feet.
•Luggage or other items are placed on the seatback or hung on the head restraint.
•The seat is washed.
•Liquids are spilled on the seat.
•The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
•The front passenger seatback contacts the rear seat.
•Luggage or other items are placed between the front passenger seat and driver seat.
•Any accessories which might increase the total seated weight on the front
passenger seat are attached to the front passenger seat.
•To assure proper deployment of the front air bag and to prevent damage to the sensors
in the front seat bottoms:
Do not place sharp objects on the front seat bottoms 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 possible 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 2-29).

Driver 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 on the front seats.

How the Side and Curtain Air Bags Work*
When air bag crash sensors detect a side impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the side and curtain air bags and after the inflation, the side
and curtain air bags quickly deflate.
The side and curtain air bags will function only once. After that, the side and curtain air
bags will not work again and must be replaced.
Only an Authorized Mazda Dealer can
replace the systems.
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 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.
•The front passenger air bag deactivation indicator light may illuminate for 10 seconds
if the total seated weight on the front passenger seat changes.
•
If the front passenger air bag deactivation indicator light does not illuminate after
installing a child-restraint system on the front passenger seat, install the child-restraint
system on the rear seat and consult an Authorized Mazda Dealer as soon as possible.
To prevent damage to the side and curtain air bag wiring, don’t place luggage or other
objects under the front seats.
The side air bag will deploy only on the side
the vehicle receives the force of the impact.The curtain air bag will deploy only on the side
the vehicle receives the force of the impact.

Driving In Flooded Area
Driving with Wet Brakes:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
affected. Dry the brakes by driving
very slowly and applying the brakes
lightly until brake performance
returns to normal.
Make sure water does not enter the
vehicle interior or the engine area. The
vehicle interior could become wet or
the engine could be damaged.
WARNING
CAUTION
Overloading
Vehicle Load Weight:
The gross axle weight rating (GAWR)
and the gross vehicle weight rating
(GVWR) of your vehicle are on the
Motor Vehicle Safety Standard Label
on the driver’s door frame. Exceeding
these ratings can cause an accident or
vehicle damage. You can estimate the
weight of your load by weighing the
items (or people) before putting them
in the vehicle. Be careful not to
overload your vehicle.
