²and the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system wiring (including the
passenger air bag deactivation switch, the system wiring, the air bag
system readiness light, the air bag back up power and the air bag
ignitors).
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster and the
passenger air bag deactivate switch or a tone to indicate the condition of
the system. Refer to theAir bag readinesssection in the
Instrumentationchapter orPassenger air bag deactivate switch
section in this chapter. Routine maintenance of the air bag is not
required.
A difficulty with the system is indicated by one or more of the following:
²The readiness lights will either
flash or stay lit.
²The readiness lights will not
illuminate immediately after
ignition is turned on.
²A 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 air bags and air bag equipped vehicles (including
safety belt pretensioners)
For disposal of safety belt pretensioners, air bags, or air bag equipped
vehicles, see your authorized Mazda dealership or qualified technician.
Air bags MUST BE disposed of by qualified personnel.
Seating and Safety Restraints

WARNING: You must turn the passenger air bag Off if you have
a rear facing child seat in the front seat of the pickup (the
center lapbelt on front split seats or the center facing rear
seats do not accommodate child seats). Statistics show that
children under 12 are more likely to suffer minor injuries in the
front passenger seats than adults. If you must have a child in
the front passenger seat, place the largest child in the front
seat, make sure that the child is belted, the vehicle seat is all
the way back, and the passenger airbag is turned OFF. The front
seat center lap belt and the center facing rear seats do not
accommodate child seats; therefore, you may not be able to put
a larger child in the front passenger seat if a child seat is
involved.
WARNING: If the OFF light fails to illuminate when the
passenger air bag switch is in the OFF position and the ignition
switch is in the ON position, have the passenger air bag switch
serviced at your authorized Mazda dealership.
WARNING: In order to avoid inadvertent activation of the
switch, always remove the ignition key from the passenger air
bag ON/OFF switch.
Turning the passenger air bag back on
The passenger air bag remains OFF until you turn it back ON.
1. Insert the ignition key and turn
the switch to ON.
2. The OFF light will briefly
illuminate when the ignition is
turned to ON. This indicates
that the passenger air bag is
operational.

WARNING: If the light is illuminated when the passenger air
bag ON/OFF switch is in the ON position and the ignition switch
is ON, have the passenger air bag ON/OFF switch serviced at
your authorized Mazda dealership immediately.
The passenger side air bag should always be ON (the air bag OFF light
shouldnotbe illuminated) except for certain vulnerable persons. See
guidance on following pages.
WARNING: The safety belts for the driver and right front
passenger seating positions have been specifically designed to
function together with the air bags in certain types of crashes.
When you turn OFF your air bag, you not only lose the
protection of the air bag, you also may reduce the effectiveness
of your safety belt system, which was designed to work with the
air bag. Most vehicles with full back seats do not have cut-off
switches, but NHTSA and Transport Canada will allow a cut-off
switch to be installed on request for a certain category of
persons who must ride up front and there is a concern about
riding there. Please see the guidance below.
WARNING: Always use safety belts and child restraints
properly. If a child in a rear facing infant seat must be
transported in front, the passenger air bagmustbe turned OFF.
This is because the back of the infant seat is too close to the
inflating air bag and the risk of a fatal injury to the infant when
the air bag inflates is substantial.
The vast majority of drivers and passengers over the age of 12 years are
much safer with an air bag than without. To do their job and reduce the
risk of life threatening injuries, air bags must open with great force, and
this force can pose a potentially deadly risk in some situations,
particularly when a front seat occupant is not properly buckled up. The
most effective way to reduce the risk of unnecessary air bag injuries
without reducing the overall safety of the vehicle is to make sure all
occupants are properly restrained in the vehicle, especially in the front
seat. This provides the protection of safety belts and permits the air bags
to provide the additional protection they were designed to provide. If
you choose to deactivate your air bag, you are losing the very significant
risk reducing benefits of the air bag and you are also reducing the

²steering wheel is turned when getting in or out of the vehicle
Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
²If the driver's safety belt is fastened, the
light may not illuminate.
Refer to theInstrument Clusterchapter for more information.
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:
²the front wheels are turned
²a 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 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
This vehicle is equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system.
NOTE:The ABS performs a self-check after you start the engine and
begin to drive away.
A brief mechanical noise may be heard during this test. This is normal. If
a malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized Mazda dealership.

The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
WARNING: The Anti-Lock system does not decrease the time
necessary to apply the brakes or always reduce stopping
distance. Always leave enough room between your vehicle and
the vehicle in front of you to stop.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle's stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.
ABS warning lamp
ABS
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned to ON. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.)

Driving while you tow
When towing a trailer:
²Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5±speed automatic transmissionsection in this
chapter.)
²Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument cluster
chapter.
²Anticipate stops and brake gradually.
²Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your service maintenance section for
more information.
Trailer towing tips
²Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.

13. Unblock the wheels.
Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel partially under the vehicle and install the wire and
retainer through the center of the wheel.
3. Turn the jack handle clockwise until the tire is raised to its original
position underneath the vehicle. The effort to turn the jack handle
increases significantly as the tire contacts the frame. The spare tire
carrier will ratchet when the tire is in the fully stowed position. The
spare tire carrier has a built-in ratchet feature that will not allow you
to overtighten. If the spare tire carrier ratchets with very little effort,
take the vehicle to your dealer for assistance at your earliest
convenience.
4. Check that the tire lies flat against the frame assembly. Push against
the tire to make sure it is tightly sealed under the vehicle. Loosen
and retighten, if necessary. Failure to properly stow the spare tire
may result in failure of the winch cable and loss of the spare tire.
5. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, per service maintenance section), or at
any time that the spare tire is disturbed through service of other
components.
6. Install the spare tire lock (if equipped) into the access hole above
the rear bumper with the spare tire lock key (if equipped) and jack
handle.
