Tire Pressure MonitoringSystem (TPMS)
▼Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
specified
value, the system
notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensors

In addition, the current tire pressures
can be checked using the center
display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
NOTE
When the ambient temperature is
low, the tire temperatures also
decrease. If the tire temperatures
decrease, the air pressure in the tires
will also decrease which could turn
on the TPMS warning light.
Before driving, visually inspect the
tires for abnormalities. Additionally,
inspect the tire pressures monthly. A
digital type air pressure gauge is
recommended for inspecting the tire
pressures.
The TPMS is not a substitute for your
own periodic inspection of the tires.
Always inspect the tires yourself
periodically.
CAUTION
 Each tire, including the spare (if
provided), should be checked
monthly when cold and
inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-inflated. Accordingly, when
the low tire pressure telltale
illuminates, you should stop and
check your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a significantly
under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.

Tires
▼Tires
For reasons of proper performance,
safety, and better fuel economy, always
maintain recommended tire
inflation
pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
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
specified for the vehicle (page 9-10)
is dangerous. It could seriously affect
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 specified for the
vehicle.

▼Replacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling could
be affected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:

Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
NOTE
When replacing a wheel, make sure
the new one is the same as the
original factory wheel in diameter,
rim width, and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

1. Park on a hard, level surface off theright-of-way and firmly set the
parking brake.
2. Put a vehicle with an automatic transmission in Park (P), a manual
transmission in Reverse (R) or 1,
and turn off the engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle and away from the vehicle
and traffic.
5. Remove any luggage, the jack, tools, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When
blocking a wheel, place a tire block
both in front and behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.
▼Removing a Flat Tire
WARNING
When jacking-up a vehicle, always
shift the shift lever to 1st or R position
(manual transmission vehicle) or shift
the selector lever to P position
(automatic transmission vehicle),
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a
flat tire without using
wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the shift lever in 1st or R
position, or the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a wheel cover, pry off the wheel
cover with the beveled end of the
jack lever.

NOTE
Force the end of the jack lever
firmly between wheel and cover, or
removal will be difficult.

Tire Labeling
▼Tire Labeling
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 tire
identification
number for safety
standard certification and in case of a
recall.
