Tire Pressure Monitoring System
lThe 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 by
indicating the tire pressure monitoring system warning light in the instrument cluster
(the warning is also indicated in the display on the type A
*1instrument 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 correctly, the system needs to be initialized with the
specified tire pressure (value on the tire pressure label). Follow the procedure and
perform the initialization.
*1 Refer to Type A on page 4-23.
lFor vehicles with the type A*1instrument cluster, check the vehicle condition or have
the vehicle inspected at an Authorized Mazda Dealer according to the indication.
*1 Refer to Type A on page 4-23.
lA system malfunction or operation conditions are indicated by a warning.

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.
Please note that the TPMS is not a substitute 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 with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. 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 instantaneously 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:
lThe size, manufacturer, or the type of tires is different from the specification.lThe size, manufacturer, or the type of a tire is different from the others, or the level of tire wear is
excessively different between them.
lA run-flat tire, studless tire, snow tire, or tire chains are used.lAn emergency tire is used (The tire pressure monitoring system warning light may flash and then
continue illuminating).
lA tire is repaired using the emergency flat tire repair kit.lThe 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.
lThe 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.
lThe vehicle is driven on an extremely rough road or a slippery, icy road.lHard steering and rapid acceleration/deceleration are repeated such as during aggressive driving
on a winding road.
lLoad on the vehicle is applied to a tire such as by loading heavy luggage to one side of the
vehicle.
lSystem initialization has not been implemented with the specified tire pressure.
qTire Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that
the system operates normally.
lA tire pressure is adjusted.lTire rotation is performed.lA tire or wheel is replaced.lThe battery is replaced or completely
drained.
lThe tire pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe 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 door jamb
of the driver's door (door open). Refer
to Tires on page 9-7.
3. Switch the ignition ON.

4. While the vehicle is parked, 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.
With instrument cluster type A, a
message indicating that the
initialization has been completed is
indicated in the instrument cluster.
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.
The system initialization will not be
performed if the switch is pressed
while the vehicle is being driven.

Blind Spot Monitoring (BSM) Systemí
The Blind Spot Monitoring (BSM) system is designed to assist the driver by monitoring
blind spots on both sides of the vehicle to the rear in certain situations such as when
changing lanes on roads and freeways or reversing the vehicle from a parking garage.
A system malfunction or operation conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page 4-23.
Refer to Blind Spot Monitoring (BSM) System Warning Beep on page 7-41.
The Blind Spot Monitoring (BSM) System consists of the Blind Spot Monitoring (BSM)
and Rear Cross Traffic Alert (RCTA).
WARNING
Do not rely completely on the Blind Spot Monitoring (BSM) system. Always look over
your shoulder before changing lanes or reversing the vehicle from a parking garage:
The Blind Spot Monitoring (BSM) system can assist the driver in confirming the
safety of the surroundings but is not a complete substitute. The driver is responsible
for assuring lane changes and other maneuvers. Always pay attention to the
direction in which the vehicle is traveling and the vehicle's surroundings.

NOTElThe detectability of the radar sensors has its limitations. The Blind Spot Monitoring (BSM) System
may not operate properly under the following conditions:
lIce, snow, or soil adheres to the rear bumper surface around the radar sensors.lDuring adverse weather conditions such as rain or snow, or under conditions where water is
sprayed.
lThe rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
lThe radar sensors do not detect human, animal, shopping cart, bicycle, or static objects such as
fences.
lThe radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
lMotorcycleslVehicles with body shapes that radar may not reflect such as a flatbed trailer with no cargo.lVehicles with lower body height such as sports cars.lAlthough the system may detect objects on the road side such as parked vehicles or guardrails and
operate the warning light/beep, it does not indicate a malfunction.
lIf the vehicle is driven on a road with less traffic and few vehicles that the radar sensors can
detect, the system may pause (the Blind Spot Monitoring (BSM) OFF indicator light in the
instrument panel flashes). However, it does not indicate a malfunction.
lThe following conditions may affect the visibility of the Blind Spot Monitoring (BSM) warning
lights on the outside mirror, making it difficult to confirm the illumination of the lights:
lIce or snow adheres to the surface of the outside mirrors.lThe door window glass is tinted.lThe radar sensors are equipped inside the rear bumper. (page 4-129)lHave the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied to the
rear bumper, even in a minor accident. If the vehicle is driven with a damaged radar sensor, the
system may not operate properly resulting in an accident.
lFor repairs or paintwork around the radar sensors, or replacement of the bumper, consult an
Authorized Mazda Dealer.
lThe radar sensors of the Blind Spot Monitoring (BSM) system may be regulated under the radio
wave related laws of the country where the vehicle is driven. The sensors in this system are
approved for use in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a
Blind Spot Monitoring (BSM) system is driven in a country other than the U.S.A., Canada, or
Mexico, the system has to be turned off using the Blind Spot Monitoring (BSM) OFF switch.

qBlind Spot Monitoring (BSM)
The Blind Spot Monitoring (BSM) system monitors the detection areas on both sides of the
vehicle to the rear and when there are vehicles in the detection area it notifies the driver by
illuminating the Blind Spot Monitoring (BSM) warning light while the vehicle speed is
about 10 km/h (6.2 mph) or faster and driving forward.
If the turn signal lever is operated to the side the Blind Spot Monitoring (BSM) warning
light is illuminated, the Blind Spot Monitoring (BSM) warning light flashes and the system
warns the driver of the vehicle in the detection area using a BSM warning beep sound.

NOTElThe Blind Spot Monitoring (BSM) does not operate when the vehicle speed is lower than about 10
km/h (6.2 mph).
lThe detection area of the Blind Spot Monitoring (BSM) has been determined based on the lane
width of general freeways. Therefore on a road with a narrower lane width, the system may detect
vehicles on a lane next to the adjacent lane and operate the warning light/beep. On a road with
wider lane width, the system may not detect vehicles on the adjacent lane and may not operate the
warning light/beep.
lUnder the following conditions, the system may be unable to detect vehicles, or detection may be
delayed.
lThe vehicle accelerates from a standing-start with a vehicle alongside.lA vehicle moves from a lane two lanes over to the adjacent lane.lThe difference in vehicle speed between your vehicle and another vehicle is larger when
passing or being passed, and the vehicle passes the detection area within a short period of
time.
lOn a steep incline, or when there is a difference in height between lanes.lImmediately after the system has been activated by pressing the Blind Spot Monitoring (BSM)
OFF switch again after it has been turned off (Blind Spot Monitoring (BSM) OFF indicator
light in instrument panel illuminates) by pressing the switch.
l(Automatic transaxle vehicles)
The selector lever is shifted to the R position, or directly after being shifted from the R position.
lThe system may not operate normally when towing a trailer. Turn off the system by operating the
Blind Spot Monitoring (BSM) OFF switch when towing a trailer.
lThe system switches to the Rear Cross Traffic Alert function when the shift lever (Manual
transaxle) or the selector lever (Automatic transaxle) is shifted to the R position.
