Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Pressure Warning Lamp will turn ON if the tire pressure is
significantly low. Once the light is illuminated, your tires are under
inflated and need to be inflated to the manufacturer’s recommended tire
pressure. Even if the light turns ON and a short time later turns OFF,
your tire pressure still needs to be checked. Visit www.checkmytires.org
for additional information.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
spare, the TPMS system will continue to identify an issue to remind you
that the damaged road wheel/tire needs to be repaired and put back on
your vehicle.
To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer toChanging tires with TPMS
in this section.

When you believe your system is not operating properly
The main function of the Tire Pressure Monitoring System is to warn you
when your tires need air. It can also warn you in the event the system is no
longer capable of functioning as intended. Please refer to the following

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being significantly
lower than the recommended inflation pressure and activate the TPMS
warning for low tire pressure. If the low tire pressure warning light is
ON, visually check each tire to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check air pressure in the road tires. If
any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.

During Trailer Sway Control events theicon in the instrument cluster
will flash momentarily. In some cases when trailer sway is detected, the
vehicle speed is too high and may be at or above a speed at which trailer
sway will grow continuously. This may cause the system to activate
multiple times, causing a gradual reduction in speed.
Disabling Trailer Sway Control
Trailer sway control can be disabled during any key cycle. Pressing and
holding the Electronic Stability Control button for more than five
seconds will disable the Trailer Sway Control feature and the
icon will
flash momentarily and then illuminate solid for that ignition cycle. Trailer
Sway Control can be re-enabled by momentarily pressing the Electronic
Stability Control button. Trailer Sway Control will also be re-enabled at
each new key cycle.
WARNING: Turning off Trailer Sway Control increases the risk
of loss of vehicle control, serious injury, or death. Mazda does
not recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
STEERING
Your vehicle is equipped with an Electric Power-Assisted Steering
(EPAS) system. There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

•The over drive cancel and grade
assist lamp in the instrument
cluster is illuminated.
2. Grade Assist
• Improves driving experience in hilly terrain or mountainous areas by
providing additional grade (engine) braking and extends lower gear
operation on uphill climbs.
• Provides additional engine braking through the automatic transmission
shift strategy which reacts to vehicle inputs (vehicle acceleration,
accelerator pedal, brake pedal and vehicle speed).
• Allows the transmission to select gears that will provide the desired
engine braking based on the vehicle inputs mentioned above. This will
increase engine RPM during engine braking.
Overdrive Cancel with Grade Assist is designed to provide optimal gear
selection in hilly terrain or mountainous areas. It is recommended that
you return to O/D (overdrive mode) on flat terrain to provide the best
fuel economy and transmission function.
To return to O/D (overdrive mode), press the transmission control switch
again.
• The over drive cancel and grade assist lamp in the instrument cluster
will not be illuminated.
• The transmission will operate in gears one through six.
O/D (overdrive mode) is automatically returned each time the engine is
turned off.
L (Low)
• Provides maximum engine braking.
• Will downshift to the lowest available gear for the current vehicle
speed; allows for first gear when vehicle reaches slower speeds.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
• do not brake heavily.
• gradually decrease the vehicle’s speed.
• hold the steering wheel firmly.
• slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). This temporary spare tire is
not equipped with a Tire Pressure Monitor System (TPMS) sensor.
Note: The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, refer to Tire Pressure Monitoring System
(TPMS) in theTires, Wheels, and Loading chapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
WARNING: The use of tire sealants may damage your Tire
Pressure Monitoring System and should not be used.

5. Use the lug wrench to removethe lug nut from the spare tire
tether.
6. If not replacing the spare or flat tire to the underbody storage
area, raise winch up into the
installed position.
7. Use the attached fastener strap (2) to tie the tether end to the
winch actuator shaft (if
equipped).
Tire change procedure
WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park) (automatic
transmission) or R (Reverse) (manual transmission).
WARNING: To prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block both
sides of the wheel that is diagonally opposite (other side and end of
the vehicle) to the tire being changed.
WARNING: Changing a tire is dangerous if not done properly. If
the vehicle slips off the jack, you or someone else could be
seriously injured. Be sure to follow the directions for changing a tire,
and never get under a vehicle that is supported only by a jack.

Never use the differentials as a
jacking point.
WARNING:To lessen the
risk of personal injury, do
not put any part of your body
under the vehicle while changing a
tire. Do not start the engine when
your vehicle is on the jack. The
jack is only meant for changing
the tire. Be sure any occupants
are out of the vehicle and in a safe
place.
4. Remove the lug nuts with the lug nut wrench.
5. Replace the flat tire with the spare tire, making sure the valve stem is facing outward. Reinstall lug nuts until the wheel is snug against
the hub. Do not fully tighten the lug nuts until the wheel has been
lowered.
6. Lower the wheel by turning the jack handle counterclockwise.
7. Remove the jack and fully tighten the lug nuts in the order
shown. Refer to Wheel lug nut
torque specifications later in
this chapter for the proper lug
nut torque specification.
