Maintenance and Care
Owner Maintenance
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inÀ ation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Diff erent Tire Types:
Driving your vehicle with diff erent
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.

Using Wrong-Sized Tires:
Using any other tire size than what is
specifi ed for the vehicle (page 9-8 )
is dangerous. It could seriously aff ect
ride, handling, ground clearance,
tire clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specifi ed for the
vehicle.

Tire InÀ ation Pressure
WARNING
Always infl ate the tires to the correct
pressure:
Overinfl ation or underinfl ation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-8 .

Use only a Mazda-genuine tire valve
cap:
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease which
could result in a serious accident. Do
not use any part for the tire valve cap
that is not a Mazda-genuine part.

Inspect all tire pressures monthly when
the tires are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tire wear.
Refer to the speci¿ cation charts (page
9-8 ).
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 .
N O T E
 


y Always check tire pressure when tires
are cold.
 


y Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.

Taking Action
Take the appropriate action and verify that the warning light turns off.

Signal Warning Action to be taken


Seat Belt Warning Light
Except Mexico
The seat belt warning light turns on if the driver
or passenger's seat is occupied and the seat belt
is not fastened with the ignition switched ON.
If the driver or passenger's seat belt is
unfastened (only when the passenger's seat is
occupied) and the vehicle is driven at a speed
faster than about 20 km/h (12 mph), the warning
light À ashes. After a short time, the warning
light stops À ashing, but remains illuminated.
N O T E
y The warning light À ashes for about 6 seconds
if the driver's seat belt is not fastened when the
ignition is switched ON.
y To allow the passenger occupant classi¿ cation
sensor to function properly, do not place
and sit on an additional seat cushion on the
passenger's seat. The sensor may not function
properly because the additional seat cushion
could cause sensor interference.
y If a small child is seated on the passenger's
seat, the warning light may not operate.
Mexico
The seat belt warning light turns on if the driver
or passenger's seat is occupied and the seat belt
is not fastened with the ignition switched ON.
If the driver or passenger's seat belt is
unfastened (only when the passenger's seat is
occupied) and the vehicle is driven at a speed
faster than about 20 km/h (12 mph), the warning

may cause the passenger's seat belt warning
function to operate depending on the weight
of the item.
y To allow the passenger seat weight sensor to
function properly, do not place and sit on an
additional seat cushion on the passenger's
seat. The sensor may not function properly
because the additional seat cushion could
cause sensor interference.
y If a small child is seated on the passenger's
seat, the warning light may not operate.
Fasten the seat belts.

P215/65R15 95H is an example of a tire size and load index rating. Here is an explanation
of the various components of that tire size and load index rating. Note that the tire size and
load index rating may be different from the example.
P
Indicates a tire that may be installed on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
N O T E
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).

215
“215” is the nominal width of the tire in millimeters. This three-digit number gives the
width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.
6 5
“65” is the aspect ratio. This two-digit number indicates the tire's ratio of height to width.
R
“R” is the tire construction symbol. R indicates “Radial ply construction”.
1 5
“15” is the wheel rim diameter in inches.
9 5
“95” is the Load Index. This two-or three-digit number indicates how much weight each tire
can support.

U.S. DOT Tire Identi¿ cation Number (TIN)
This begins with the letters “DOT” which indicates the tire meets all federal standards. The
next two numbers or letters are the plant code where it was manufactured, and the last four
numbers represent the week and year the tire was manufactured. For example, the numbers
457 means the 45st week of 1997. After 2000 the numbers go to four digits. For example,
the number 2102 means the 21th week of 2002. The other numbers are marketing codes
used at the manufacturer's discretion. This information is used to contact consumers if a tire
defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-coated fabric in the tire.
In general, the greater the number of plies, the more weight a tire can support. Tire
manufacturers also must indicate the tire materials, which include steel, nylon, polyester,
and other.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by the
tire.

Vehicle Loading
WARNING
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is dangerous because it has not been designed to tow a
trailer and doing so will aff ect the drive system which could result in vehicle damage.

This section will guide you in the proper loading of your vehicle, to keep your loaded
vehicle weight within its design rating capability. Properly loading your vehicle will provide
maximum return of vehicle design performance. Before loading your vehicle, familiarize
yourself with the following terms for determining your vehicle's weight ratings, from the
vehicle's Safety Certi¿ cation Label and Tire and Load Information Label:
WARNING
Overloaded Vehicle:
Overloading a vehicle is dangerous. The results of overloading can have serious
consequences in terms of passenger safety. Too much weight on a vehicle's suspension
system can cause spring or shock absorber failure, brake failure, handling or steering
problems, irregular tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also increases the distance
required for stopping. In cases of serious overloading, brakes can fail completely,
particularly on steep grades. The load a tire will carry safely is a combination of the size of
the tire, its load range, and corresponding infl ation pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certifi cation and Tire and Load Information labels.
