Front seat belt usage sensors
The front seat belt usage sensors detect whether or not the driver and
front outboard passenger seat belts are fastened. This information allows
your Personal Safety System™ to tailor the airbag deployment and seat
belt pretensioner activation depending upon seat belt usage. Refer to
Seat belt usage sensorslater in this chapter.
Front outboard seat belt pretensioners
The seat belt pretensioners at the front outboard seating positions are
designed to tighten the seat belts firmly against the occupant’s body
during frontal collisions. This helps increase the effectiveness of the seat
belts. In frontal collisions, the seat belt pretensioners can be activated
alone or, if the collision is of sufficient severity, together with the front
airbags.
Front outboard seat belt energy management retractors
The front seat belt energy management retractors allow webbing to be
pulled out of the retractor in a gradual and controlled manner in
response to the occupant’s forward momentum. This helps reduce the
risk of force-related injuries to the occupant’s chest by limiting the load
on the occupant. Refer toEnergy management retractorssection in
this chapter.
Determining if the Personal Safety System™ is operational
The Personal Safety System™ uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System™ is not
required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
seat belt pretensioners, front seat belt buckle sensors, front passenger
sensing system, and the driver seat position sensor. In addition, the RCM
also monitors the restraints warning light in the instrument cluster. A
difficulty with the system is indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.

The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, it may also
cause minor abrasions, swelling or temporary hearing loss. Because
airbags must inflate rapidly and with considerable force, there is the risk
of death or serious injuries such as fractures, facial and eye injuries or
internal injuries, particularly to occupants who are not properly
restrained or are otherwise out of position at the time of airbag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the airbag module as possible while
maintaining vehicle control.
WARNING: Several airbag system components get hot after
inflation. Do not touch them after inflation or you may be
burned.
WARNING: If the air bag has deployed, the air bag will not
function again and must be replaced immediately. If the air bag
is not replaced, the unrepaired area will increase the risk of
injury in a collision.
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAirbag readiness
section in theInstrumentationchapter. Routine maintenance of the
airbag is not required.

A difficulty with the system is indicated by one or more of the following:
•The readiness lights will either
flash or stay lit.
•The readiness lights will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your authorized Mazda dealership immediately.
WARNING: Unless serviced, the system may not function
properly in the event of a collision.
Disposal of airbags and airbag equipped vehicles
(including seat belt pretensioners)
For disposal of seat belt pretensioners, airbags, or airbag equipped
vehicles, see your authorized Mazda dealership or qualified technician.
Airbags MUST BE disposed of by qualified personnel.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The driver’s frontal air bag is not
part of the front passenger sensing system. The front passenger sensing
system works with sensors that are part of the front passenger’s seat and
seat belt. The sensors are designed to detect the presence of a properly
seated occupant and determine if the front passenger’s frontal air bag
should be enabled (may inflate) or not.
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to turn off the front passenger’s frontal air bag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat,
•the system determines that a small child is present in a rear-facing
child seat that is installed according to the manufacturer’s instructions.
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions,

malfunctionIf your tires are properly
inflated and your spare tire is
not in use and the TPMS
warning light still flashes, have
the system inspected by your
authorized dealer.
When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being significantly
lower than the recommended inflation pressure and activate the TPMS
warning for low tire pressure. If the low tire pressure warning light is
ON, visually check each tire to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check air pressure in the road tires. If

WARNING: Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not
have enough braking power and your chances of having a
collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
authorized dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.
Using a step bumper
The optional step bumper is equipped with an integral hitch and requires
only a ball with a 3/4 inch (19 mm) shank diameter. The bumper has a
2,000 lb. (907 kg) trailer weight and 200 lb. (91 kg) tongue weight
capability.
The rated capacities (as shown in this guide) for trailer towing with the
factory bumper are only valid when the trailer hitch ball is installed
directly into the ball hole in the bumper. Addition of bracketry to either
lower the ball hitch position or extend the ball hitch rearward will
significantly increase the loads on the bumper and its attachments. This
can result in the failure of the bumper or the bumper attachments. Use
of any type of hitch extensions should be considered abuse.
Trailer tow connector
The trailer tow connector is located
under the rear bumper, on the
driver’s side of the vehicle.

steering wheel. This position also allows the automatic transmission
shift lever to be moved from the P (Park) position without the brake
pedal being depressed.
WARNING: When the key is in the ignition and in the OFF
position, the automatic transmission shift lever can be moved
from the P (Park) position without the brake pedal depressed.
To avoid unwanted vehicle movement, always set the parking
brake.
Note:On some vehicles, when the key is in the OFF position, the
brake-shift interlock feature will prevent the automatic transmission shift
lever from being moved out of the P (Park) position without the brake
pedal being depressed.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle

Some warning lights will briefly illuminate. SeeWarning lights and
chimesin theInstrument Clusterchapter for more information
regarding the warning lights.
Starting the engine
Note:Whenever you start your vehicle, release the key as soon as the
engine starts. Excessive cranking could damage the starter.
1. Turn the key to 4 (ON) without
turning the key to 5 (START). If
there is difficulty in turning the
key, rotate the steering wheel
until the key turns freely. This
condition may occur when:
•the front wheels are turned
•a front wheel is against the curb
Turn the key to 5 (START), then
release the key as soon as the
engine starts. Excessive cranking could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to OFF, wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING: If you smell exhaust fumes inside your vehicle,
have your dealer inspect your vehicle immediately. Do not drive
if you smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.

Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems, try a different brand of unleaded gasoline. “Premium”
unleaded gasoline is not recommended for vehicles designed to use
“Regular” unleaded gasoline because it may cause these problems to
become more pronounced. If the problems persist, see your authorized
dealer.
Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.
Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from OFF to ON several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than 1
gallon (3.8L) may be required.
•The
indicator may come on. For more information on the “check
engine” or the “service engine soon” indicator, refer toWarning lights
and chimesin theInstrument Clusterchapter.
