Do not use the front bumper to push other vehicles or obstructions such as when pulling
out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or modify the radar sensor (front).
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
 Do not modify the suspension. If the suspension are modified, the vehicle's posture could
change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.
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 trunk/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
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly.

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver b y indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate c orrectly, the system needs to be initialized with the specified
tire pressure (value on the tire pressure label). Follow the pr ocedure and perform the
initialization.
Refer to Tire Pressure Monitorin g System Initialization on page 4-148.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on page 4-24.

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 in flation 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 pressu re 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-infla ted 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.
Please note that the TPMS is not a substitu te for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined wi th the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for approximately one minute and then
remain continuously illuminate d. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
 To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantane ously register a rapid tire
deflation or blow out.
NOTE
Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases:
The size, manufacturer, or the type of
tires is different from the specification.
The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them.
A run-flat tire, studless tire, snow tire, or tire chains are used.

An emergency tire is used (The tire pressure monitoring system warning light may flash
and then continue illuminating).
A tire is repaired using the emergency flat tire repair kit.
The tire pressure is excessively higher than the specified pressure, or the tire pressure is
suddenly lowered for some reason such as a tire burst during driving.
The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle is
stopped), or the drive period is shorter than 5 minutes.
The vehicle is driven on an extremely rough road or a slippery, icy road.
Hard steering and rapid acceleration/decelera tion are repeated such as during aggressive
driving on a winding road.
Load on the vehicle is applied to a tire such as by loading heavy luggage to one side of
the vehicle.
System initialization has not been implem ented with the specified tire pressure.
▼Tire Pressure Monitoring System
Initialization
In the following cases, system
initialization must be
performed so that the
system operates normally.
A tire pressure is adjusted.
Tire rotation is performed.
A tire or wheel is replaced.
The battery is repl aced or completely
drained.
The tire pressure monitoring system
warning light is illuminated.

Initialization method
1. Park the car in a sa fe place and firmly
apply the parking brake.
2. Let the tires cool, then adjust the tire pressure of all four (4) tires to the
specified pressure indicated on the tire
pressure label located on the driver's
door frame (door open).
Refer to Tires on page 9-10.
3. Switch the ignition ON.
4. Press and hold the tire pressure monitoring system set switch and
verify that the tire pressure monitoring
system warning light in the instrument
cluster flashes twice and a beep sound
is heard once.

CAUTION
If the system initialization is performed
without adjusting the tire pressure, the
system cannot detect the normal tire
pressure and it may not illuminate the tire
pressure monitoring system warning light
even if a tire pressure is low, or it may
illuminate the light even if the pressures are
normal.
Adjust the tire pressure on all four tires and
initialize the system when the warning
light is turned on. If the warning light turns
on for a reason other than a flat tire, the
tire pressure of all four tires may have
decreased naturally.
The system initialization will not be
performed if the switch is pressed while the
vehicle is being driven.
