NOTE
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not reflect radio waves effectively, such as an
unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for reflecting radio waves.
Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its tires
and onto your windshield.
The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
Ice, snow, or soiling is on the front surface of the front emblem.
During inclement weather such as rain, snow, or sand storms.
When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
Narrow lane roads due to road construction or lane closures.
The vehicle ahead enters the radar sensor's blind spot.
The vehicle ahead is running abnormally due to accident or vehicle damage.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more t ires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-31.
Refer to Taking Action on page 7-37.
Refer to Tire Inflation Pressure Warning Beep on page 7-50.

The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illuminate more frequently. Vi sually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.
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.)

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.
WA R N I N G
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 9-7) 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.
▼ Tire Inflation Pressure
WA R N I N G
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 9-7.
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 recomm ended pressures for
the best ride, handli ng, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequen tly needs inflating,
have it inspected.

▼Replacing a Wheel
WA R N I N G
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.

Changing a Flat Tire
NOTE
If the following occurs while driving, it
could indicate a flat tire.
Steering becomes difficult.
The vehicle begins to vibrate
excessively.
The vehicle pulls in one direction.
If you have a flat tire, drive slowly to a
level spot that is well off the road and out
of the way of traffic to change the tire.
Stopping in traffic or on the shoulder of a
busy road is dangerous.
WA R N I N G
Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not done
properly. The vehicle can slip off the jack
and seriously injure someone.
No person should place any portion of their
body under a vehicle th at is supported by a
jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a vehicle
supported by a jack is dangerous. The
occupant could cause the vehicle to fall
resulting in serious injury.
NOTE
Make sure the jack is well lubricated
before using it.
1. Park on a hard, level surface off the right-of-way and firmly set the parking
brake.
2. Shift into Park (P ) 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
WA R N I N G
When jacking-up a vehicle, always shift the
selector lever to P, 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 select lever is in P, which could result in
an accident.
