▼Front Passenger Seat Weight
Sensors
Your vehicle is equipped with a front
passenger seat weight sensors as a part of
the supplemental restraint system. These
sensors are located under both of the front
passenger seat rails. These sensors
determine the total
seated weight on the
front passenger seat and monitor the seat
belt buckle for the front passenger seat.
The SAS unit is designed to prevent the
front passenger front and side air bags and
knee air bags, and seat belt pretensioner
system from deploying if the front
passenger air bag deactivation indicator
light illuminates.
To reduce the chance of injuries caused by
deployment of the fr ont passenger air bag,
the system deactivates the front passenger
front and side air bags and knee air bags,
and also the seat belt pretensioner system
when the front passenger air bag
deactivation indicator light illuminates.
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 knee air bags,
and seat belt pretensioner system, so make
sure the front passenger air bag
deactivation indicator light illuminates
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
possible malfunction. If this happens, the
front passenger front and side air bags and
knee air bags, and seat belt pretensioner
system will not deploy.
Front passenger air bag deactivation
indicator light
This indicator light illuminates to remind
you that the front passenger front and side
air bags and knee air bags, and seat belt
pretensioners will not deploy during a
collision.
If the front passenger weight sensors are
normal, the indicator light illuminates
when the ignition is switched ON. The
light turns off after a few seconds. Then,
the indicator light illuminates or is off
under the following conditions:

If the front passenger air bag deactivation
indicator light does not illuminate when
the ignition is switched ON and does not
illuminate as indicated in the front
passenger air bag deactivation indicator
light on/off condition chart, do not allow a
child to sit in the front passenger seat and
consult an Authorized Mazda Dealer as
soon as possible. The system may not
work properly in an accident.
WA R N I N G
Do not decrease the total seated weight on
the front passenger seat:
When an adult or large child sits on the
front passenger seat, decreasing the total
seated weight on the front passenger seat
required for air bag deployment is
dangerous. The front passenger seat
weight sensors will de tect the reduced total
seated weight condition and the front
passenger front and side air bags and knee
air bags, and the seat belt pretensioner
system will not deploy during an accident.
The front passenger will not have the
supplementary protection of the air bag,
which could result in serious injury.
Decreasing the total seated weight on the
front passenger seat could result in an air
bag not deploying under the following
conditions, 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.
 Any accessories which might decrease
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 knee air bags, and the seat belt
pretensioner system will deactivate if the
front passenger air bag deactivation
indicator light illuminates.

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 th e 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 knee
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 knee 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.

▼Driving In Flooded Area
WA R N I N G
Dry off brakes that have become wet by
driving slowly, releasing the accelerator
pedal and lightly applying the brakes
several times until the brake performance
returns to normal:
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.
CAUTION
Do not drive the vehicle on flooded roads
as it could cause short circuiting of
electrical/electronic parts, or engine
damage or stalling from water absorption.
If the vehicle has been immersed in water,
consult an Authorized Mazda Dealer.
Overloading
▼ Overloading
WA R N I N G
Be careful not to overload your vehicle:
The gross axle weight rating (GAWR) and
the gross vehicle weight rating (GVWR) of
the vehicle are on the Motor Vehicle Safety
Standard Label on the driver's door frame.

Driving Tips
▼Driving Tips
WA R N I N G
Do not let the vehicle move in a direction
opposite to the direction selected by the
selector lever:
Do not let the vehicle move backward with
the selector lever in a forward position, or
do not let the vehicle move forward with
the selector lever in the reverse position.
Otherwise, the engine may stop, causing
the loss of the power brake and power
steering functions, and make it
difficult to
control the vehicle which could result in an
accident.
Passing
For extra power wh en passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transmission will
shift to a lower gear, depending on vehicle
speed.
NOTE
The accelerator pedal may initially feel
heavy as it is being depressed, then feel
lighter as it is depressed further. This
change in pedal force aids the engine
control system in determining how much
the accelerator pedal has been
depressed for performing kickdown, and
functions to control whether or not
kickdown should be performed.
While the selector lever is in the M
position and the DSC is turned off,
manual shift mode does not switch to
automatic shift mode even if the
accelerator pedal is completely
depressed. Operate the selector lever.
Climbing steep gra des from a stop
To climb a steep grade from a stopped
position:
1. Depress the brake pedal.
2. Shift to D or M1, depending on the load weight and grade steepness.
3. Release the brake pedal while gradually accelerating.
Descending steep grades
When descending a steep grade, shift to
lower gears, depending on load weight and
grade steepness. Descend slowly, using the
brakes only occasionally to prevent them
from overheating.
