Tire Pressure MonitoringSystem (TPMS)
The TPMS monitors the air pressure of
each tire and informs the driver of a
decrease in the tire air pressure when it
becomes lower than the specified air
pressure.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.

Warning and Cautions forUsing the Tire Pressure Monitoring System
(TPMS)
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light
is
turned on or flashing.
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 brake and reduce
the vehicle 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.

Radar Sensors*
The radar sensor detects objects by
sending radio waves in a specific
direction and receiving the reflected
waves back.

CAUTION
 Heed the following cautions so that
the radar sensors can function
normally.
 Do not modify the suspensions.
 Always use tires of the specified
size and the same manufacturer,
brand, and tread pattern on all 4
wheels. In addition, do not use
tires with significantly different
wear patterns or tire pressures on
the same vehicle (including
temporary spare tire).
Do not spray highly pressurized
water against the radar sensors or
rub them strongly.
 Do not apply stickers on parts near
the radar sensors.
 If foreign matter adheres to parts
near the radar sensors, remove it
and switch the vehicle power OFF.
The foreign matter detection status
is reset by switching the vehicle
power OFF.
 Consult an Authorized Mazda
Dealer if you need to repair,
replace, or paint parts near the
radar sensors.
 Do not install any parts that cover
the front of the radar sensors.
 Do not replace the radiator grille
and emblem with anything other
than genuine products.
 If strong force is applied to parts near
the radar sensors, the direction of
the radar sensor may become
deviated and each system may not
operate normally. Stop each system
immediately and have the vehicle
inspected by an Authorized Mazda
Dealer.
NOTE
The radar sensors include a function
for detecting abnormalities in the

How to Use the Rear
Cross Traffic Alert (RCTA)
Operating the RCTA
The RCTA operates when all of the
following conditions are met.
The vehicle is about to be driven in
reverse.
The system detects an approaching
vehicle.
When the RCTA operates, the driver is
notified of the danger by flashing of
the BSM warning lights, a warning
indication, and a warning sound.
NOTE
The system may operate even if a
vehicle is not approaching
depending on the conditions around
your vehicle.
The RCTA may not operate normally
if any of the following conditions is
met.
The rear side radar sensors cannot
detect an object.
Refer to Radar Sensors on page
5-131.
The vehicle speed when reversing
is about 15 km/h (9 mph) or
faster.
A vehicle is approaching directly
from the rear of your vehicle.
A vehicle is approaching at an
angle from the rear of your vehicle.
If a Mazda genuine trailer hitch is
used, the RCTA is automatically
turned off when the trailer's
electrical connector is connected.
When pulling a trailer other than
with a Mazda genuine trailer hitch,
or while an accessory such as a
bicycle carrier is installed to the rear
of the vehicle, turn off the RCTA.
Otherwise, the radar’s radio waves
will be blocked causing the RCTA to
not operate normally.
The brightness of the BSM warning
lights is linked to the panel light
control.
Refer to Dashboard Illumination on
page 5-35.
Turning off the RCTA
There are 2 ways to turn off the RCTA.
Turn off the RCTA using Mazda
Connect.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
Turn off the RCTA using the
i-ACTIVSENSE OFF switch.
