▼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:

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:

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.

Liftgate/Trunk Lid
▼Liftgate/Trunk Lid
WA R N I N G
Never allow a person to ride in the luggage
compartment/trunk:
Allowing a person to ride in the luggage
compartment/trunk is dangerous. The
person in the luggage compartment/trunk
could be seriously injured or killed during
sudden braking or a collision.
Do not drive with the liftgate/trunk lid
open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate/trunk lid in a
moving vehicle will cause exhaust gas to be
drawn into the cabin. This gas contains CO
(carbon monoxide), which is colorless,
odorless, and highly poisonous, and it can
cause loss of consciousness and death.
Moreover, an open lift
gate/trunk lid could
cause occupants to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage compartment:
Otherwise, the luggage may move or
collapse, resulting in injury or an accident.
In addition, do not load luggage higher
than the seatbacks. It may affect the side or
rear field of view.
CAUTION
 Before opening the liftgate/trunk lid,
remove any snow and ice accumulation
on it. Otherwise, the liftgate/trunk lid
could close under the weight of the snow
and ice resulting in injury.
 Be careful when opening/closing the
liftgate/trunk lid during strong winds. If a
strong gust blows against the liftgate/
trunk lid, it could close suddenly resulting
in injury.
 Fully open the liftgate/trunk lid and
make sure that it stays open. If the
liftgate/trunk lid is only opened partially,
it could slam shut by vibration or wind
gusts resulting in injury.
 When loading or unloading luggage in
the luggage compartm ent/trunk, turn off
the engine. Otherwise, you could get
burned by the heat of the exhaust gas.
 Be careful not to apply excessive force to
the damper stay on the liftgate such as
by putting your hand on the stay.
Otherwise, the damper stay may bend
and
affect the liftgate operation.

▼ Luggage Compartment
Luggage compartment cover (5-door)
WA R N I N G
Do not place anything on top of the cover:
Placing luggage or other cargo on top of
the luggage compartment cover is
dangerous. During sudden 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 sight;
it will not retain heavy objects 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.
Make sure luggage and cargo are 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.
The luggage compartment can be accessed
by opening the liftgate when the straps are
attached to the sides of the liftgate.

Driving In Flooded Area
▼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 when 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 grades 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. Desce nd slowly, using the
brakes only occasionally to prevent them
from overheating.
