Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
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.

8.U.S. DOT Tire Identification Number (TIN):This begins with
the letters“DOT”and indicates that the tire meets all federal
standards. The next two numbers or letters are the plant code
designating where it was manufactured, the next two are the tire
size code and the last four numbers represent the week and year the
tire was built. For example, the numbers 317 mean the 31st week of
1997. After 2000 the numbers go to four digits. For example, 2501
means the 25th week of 2001. The numbers in between are
identification codes used for traceability. This information is used to
contact customers if a tire defect requires a recall.
9.M+S or M/S:Mud and Snow, or
AT:All Terrain, or
AS:All Season.
10.Tire Ply Composition and Material Used:Indicates the number
of plies or the number of layers of rubber-coated fabric in the tire
tread and sidewall. Tire manufacturers also must indicate the ply
materials in the tire and the sidewall, which include steel, nylon,
polyester, and others.
11.Maximum Load:Indicates the maximum load in kilograms and
pounds that can be carried by the tire. Refer to the tire label or the
safety certification label, which is located on the B-Pillar or the edge
of the driver’s door, for the correct tire pressure for your vehicle.

Four-wheel anti-lock brake system (ABS)
Since your 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 four wheel ABS
•In an emergency or when maximum efficiency from the ABS is
required, apply continuous force on the brake. The ABS will be
activated immediately, thus allowing you to retain steering control of
your vehicle and, providing there is sufficient space, will enable you to
avoid obstacles and bring the vehicle to a controlled stop.
NOTE:We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.

Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
NOTE:
•If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
•When driving through water,
determine the depth; avoid water
higher than the bottom of the
hubs (if possible) and proceed
slowly. If the ignition system gets wet, the vehicle may stall.
•Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
After driving through mud, clean off residue stuck to rotating
driveshafts, halfshafts and tires. Excess mud on tires and rotating
driveshafts causes an imbalance that could damage drive
components.
NOTE:
If the transaxle Power Take Off unit or rear axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the rear axle is submerged in water, the axle lubricant should be
checked and changed, if necessary. The rear axle is filled with a lubricant
that does not normally require a lubricant change for the life of the
vehicle. Rear axle lubricant quantities should not need to be checked
unless a leak is suspected.

“Tread Lightly”is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Mazda Motor
Corporation joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by“treading lightly.”
Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Avoid driving crosswise or turning on steep
slopes or hills. A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill,
start in a lower gear rather than
downshifting to a lower gear from a
higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of stalling.
If you do stall out, Do not try to
turnaround because you might roll
over. It is better to back down to a
safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.

•4WD vehicles should be driven with traction devices as referred to in
Using snow tires and traction devicesin theTires, Wheels and
Loadingchapter.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Mazda Motor
Corporation strongly recommends that you do not make modifications
such as adding or removing parts (such as lift kits or stabilizer bars) or
by using replacement parts not equivalent to the original factory
equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Mazda Motor Corporation recommends that caution be used with any
vehicle equipped with a high load or device (such as ladder racks or
pickup box cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the
depth is unknown. Traction or brake capability may be limited
and if the ignition system gets wet, your engine may stall. Water
may also enter your engine’s air intake and severely damage your
engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage. Have the fluid checked and, if
water is found, replace the fluid.
