•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.

Power is supplied to all four wheels
through a transfer case or power
transfer unit. 4WD vehicles allow
you to select different drive modes
as necessary. Information on shifting
procedures and maintenance can be
found in yourOwner’s Guide.You
should become thoroughly familiar
with this information before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
WARNING: Do not become overconfident in the ability of 4WD
and AWD vehicles. Although a 4WD or AWD vehicle may
accelerate better than two-wheel drive vehicle in low traction
situations, it won’t stop any faster than two-wheel drive
vehicles. Always drive at a safe speed.
How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
•Higher–to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
•Shorter–to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle quicker to respond to steering
inputs than a vehicle with a longer wheelbase.

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.

Information on“T”type tires
“T”type tires have some additional
information beyond those of“P”
type tires; these differences are
described below:
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example.
1.T:Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service
on cars, SUVs, minivans and
light trucks.
2.145: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.
3.80:Indicates the aspect ratio which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
4.D:Indicates a“diagonal”type tire.
R:Indicates a“radial”type tire.
5.16:Indicates the wheel or rim diameter in inches. If you change
your wheel size, you will have to purchase new tires to match the
new wheel diameter.
Location of the tire label
You will find a tire label containing tire inflation pressure by tire size and
other important information located on the B-Pillar or the edge of the
driver’s door.
TIRE CARE
Improper or inadequate vehicle maintenance can also cause tires to wear
abnormally. Here are some of the important maintenance items:
Tire wear
Measure and inspect the tire tread on all your tires periodically.
Advanced and unusual tire wear can reduce the ability of tread to grip

Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Scheduled maintenancesection of theMaintenance and
Specificationschapter) will help your tires wear more evenly, providing
better tire performance and longer tire life.

Driving while you tow
When towing a trailer:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To 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 the
Drivingchapter.)
•Under 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.
•Anticipate stops and brake gradually.
•Do 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 yourService Maintenance Section
for more information.

5. Check the coolant level. If it is low, look for leaks in the radiator
hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an Authorized Mazda dealer.
SeeAdding coolantin theMaintenance and specificationssection. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note:If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
JUMP STARTING YOUR VEHICLE
WARNING: The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING: Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; doing so may
damage the catalytic converter.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
