•and 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:
•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 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.

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

and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
NOTE:The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
WARNING: The temperature grade for this tire is established
for a tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and
possible tire failure.
TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.

INSPECTING AND INFLATING YOUR TIRES
Safe operation of your vehicle requires that your tires are properly
inflated. Remember that a tire can lose up to half of its air pressure
without appearing flat.
Every day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to check
pressure of all tires and adjust if
required.
At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge (including spare, if equipped).
Inflate all tires to the inflation
pressure recommended by Mazda.
Inspecting your tires
Periodically inspect the tire treads for uneven or excessive wear and
remove stones, nails, glass or other objects that may be wedged in the
tread grooves. Check for holes or cuts that may permit air leakage from
the tire and make necessary repairs.
Also inspect the tire sidewalls for cuts, bruises and other damage. If
internal damage to the tire is suspected, have the tire demounted and
inspected in case it needs to be repaired or replaced. For your safety,
tires that are damaged should not be used because they are more likely
to blow out or fail. Tires can be damaged during off-road use, so
inspection after off-road use is also recommended.
Inflating your tires
Use a tire gauge to check the tire inflation pressure, including the spare
(if equipped), at least monthly and before long trips. You are strongly
urged to buy a reliable tire pressure gauge, as automatic service station
gauges may be inaccurate. Mazda recommends the use of a digital or dial
type tire pressure gauge rather than a stick type tire pressure gauge.
Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.
NOTE:If you are driving the vehicle at its maximum weight load, make
sure the tire inflation pressure is correct for the weight load on the tires.

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 seated 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, perService 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.

WARNING: When a wheel is installed, always remove any
corrosion, dirt and foreign materials present on the mounting
surfaces of the wheel and the surface of the front disc brake
hub and rotor that contacts the wheel. Installing wheels
without correct metal-to-metal contact at the wheel mounting
surfaces can cause the wheel nuts to loosen and the wheel to
come off while the vehicle is in motion, resulting in loss of
control.
Note:If there is corrosion on the area where the wheel contacts the
hub, apply a thin film of grease or anti-seize compound on that area.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires. This information identifies and
describes the fundamental characteristics of the tire and also provides a
U.S. DOT Tire Identification Number for safety standard certification and
in case of a recall.
Information on“P”type tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
1.P:Indicates a tire, designated
by the Tire and Rim Association
(T&RA), that may be used for
service on cars, SUVs, minivans
and light trucks.
Note:If your tire size does not
begin with a letter this may mean it
is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire
Manufacturing Association).
2.215:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.

•Temperature:The temperature grades are A (the highest), B and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel.
13.Maximum Permissible Inflation Pressure:Indicates the tire
manufacturers’maximum permissible pressure and/or the pressure at
which the maximum load can be carried by the tire. This pressure is
normally higher than the manufacturer’s recommended cold inflation
pressure which can be found on either the tire label or certification
label which is located on the B-Pillar or the edge of the driver’s door.
The cold inflation pressure should never be set lower than the
recommended pressure on the vehicle label.
The tire suppliers may have additional markings, notes or warnings such
as standard load, radial tubeless, etc.
Additional information contained on the tire sidewall for“LT”type
tires
“LT”type tires have some additional
information beyond those of“P”
type tires; these differences are
described below:
1.LT:Indicates a tire, designated
by the Tire and Rim Association
(T&RA), that is intended for
service on light trucks.
2.Load Range/Load Inflation
Limits:Indicates the tire’s
load-carrying capabilities and its
inflation limits.
3.Maximum Load Dual lb. (kg)
at psi (kPa) cold:Indicates
the maximum load and tire
pressure when the tire is used as a dual; defined as four tires on the
rear axle (a total of six or more tires on the vehicle).
4.Maximum Load Single lb. (kg) at psi (kPa) cold:Indicates the
maximum load and tire pressure when the tire is used as a single;
defined as two tires (total) on the rear axle.
