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 selector lever to P position,
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 selector lever is in P
position, which could result in an
accident.
1. Loosen the lug nuts by turning them counterclockwise one turn each,
but do not remove any lug nuts
until the tire has been raised off the
ground.
NOTE
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a
special key must be used to unlock
the locking lug nut for each wheel.
For details, refer to “Locking Lug
Nuts” below.
2. Place the jack on the ground.
3. Turn the jack screw in the direction shown in the figure and adjust the
jack head so that it is close to the
jack-up position.
4. Place the jack under the jack-upposition closest to the tire being
changed with the jack head
squarely under the jack-up point.
5. Continue raising the jack headgradually by rotating the screw with
your hand until the jack head is
inserted into the jack-up position.

AWD Warning Light
The light turns on if the system has a
problem or if the tire sizes do not
match.
Check the contents of the message
displayed and take the necessary
action.
Tire Pressure MonitoringSystem (TPMS) Warning Light (Flashing)
The light flashes if there is a
malfunction in the system.
Contact an Authorized Mazda Dealer.
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or flashes:
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brakes to lower the
vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.

Inspecting the Tires
About Tires
For reasons of proper performance,
safety, and better energy efficiency,
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
10-71)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.

Inspecting tire inflation pressure
WARNING
Always inflate the tires to the correct
pressure.
Overinflation or underinflation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 10-71.
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
(including the spare) when the tires are
cold. Maintain recommended
pressures for the best ride, handling ,
and minimum tire wear.
Refer to the specification charts (page
10-71).
NOTE
Cold inflation pressure
The cold inflation pressure is the
pressure measured under ambient
temperatures before the vehicle is
driven.
Maximum inflation pressure
The maximum inflation pressure is
the upper limit of the cold inflation
pressure designated by the tire
manufacturer.
Recommended inflation pressure
The recommended inflation pressure
is the cold inflation pressure
necessary for maintaining the
performance of your Mazda.
Underinflation or overinflation can
cause a harsh ride, reduced fuel
economy, a greater possibility of
damage from road hazards, uneven
and accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.
