2023 MAZDA MODEL CX-50 brake sensor

Front Radar Sensor*
▼Front Radar Sensor
Your vehicle is equipped with a front
radar sensor.
1. Front radar sensor

The following systems also use the
front radar sensor.
Distance & Speed Alert (DSA)Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
Tra ffi c
Jam Assist (TJA)Smart Brake Support (SBS) forward
drive detection
The front radar sensor functions by
detecting the radio waves reflected off
a vehicle ahead or an obstruction sent
from the radar sensor.
CAUTION
Heed the following precautions to
assure correct operation of each
system.
 Do not apply a sticker (including a
transparent one) to the front radar
sensor cover or replace the front
radar sensor cover with a product
other than a genuine product.
The front radar sensor includes a
function for detecting soiling of the
radar sensor's front surface and
informing the driver, however,
depending on the conditions, it may
require time to detect or it may not
detect plastic shopping bags, ice or
snow. If this occurs, the system may
not operate correctly, therefore
always keep the front radar sensor
clean.
 If “Safety and Driver Support Systems
Temporarily Disabled. Front Radar
Obscured. Drive Safely” is displayed
on the multi-information display of
the instrument cluster, clean the area
around the front radar sensor.
 Do not install a grille guard.
 If the front part of the vehicle has
been damaged in a vehicle accident,
the position of the front radar sensor
may have moved. Stop the system
immediately and always have the
vehicle inspected at an Authorized
Mazda Dealer.
 Do not use the front bumper to push
other vehicles or obstructions such
as when pulling out of a parking
space. Otherwise, the front radar
sensor could be hit and its position
deviated.
 For repairs, replacement or paint
work around the front radar sensor,
consult an Authorized Mazda Dealer.
 Always use tires for all wheels that
are of the specified size, and the
same manufacturer, brand, and tread
pattern. In addition, do not use tires
with significantly different wear
patterns on the same vehicle as the
system may not operate normally.
NOTE
If the battery power is weak, the
system may not operate correctly.

Rear Side Radar Sensor*
▼Rear Side Radar Sensor
Your vehicle is equipped with rear side
radar sensor.
1. Rear side radar sensor

The following systems also use the rear
side radar sensor.
Blind Spot Monitoring (BSM)Rear Cross
Tra ffi c Alert (RCTA)Smart Brake Support (SBS) reverse
drive detection
Emergency Lane Keeping (ELK)
The rear side radar sensors emit radio
waves and detect the radio waves
reflected off a vehicle approaching
from the rear or an obstruction.
CAUTION
Heed the following precautions to
assure correct operation of each
system.
 Always keep the surface of the rear
bumper near the rear side radar
sensors clean so that they operate
normally. Also, do not apply items
such as stickers.
Refer to Exterior Care on page
6-43.
If the rear bumper receives a severe
impact, the system may no longer
operate normally. Stop the system
immediately and have the vehicle
inspected at an Authorized Mazda
Dealer.
 Vehicles are shipped with the
direction of the rear side radar
sensor adjusted for each vehicle to a
loaded vehicle condition so that the
rear side radar sensor detect
approaching vehicles correctly. If the
direction of the rear side radar
sensor has deviated for some reason,
have the vehicle inspected at an
Authorized Mazda Dealer.
 For repairs or replacement of the rear
side radar sensor, or bumper repairs,
paintwork, and replacement near the
radar sensors, consult an Authorized
Mazda Dealer.
NOTE
The radar sensors are regulated by the
relevant radio wave laws of the country
in which the vehicle is driven. If the
vehicle is driven abroad, authorization
from the country in which the vehicle is
driven may be required.
When any of the following conditions
is met, the detection ability of the rear
side radar sensors may decrease and
each system may not operate normally.
Under bad weather conditions (rain,
fog , and snow).
The rear bumper around a rear side
radar sensor is deformed.
Foreign matter (such as ice, snow,
and mud) is adhering to the rear
bumper around a rear side radar
sensor.
The rear side radar sensors may not
detect the following target objects.
Small motorcycles

Anything which generates ultrasonic waves such as another vehicle's horn, the
engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors approaches the vehicle.
The vehicle is driven in heavy rain or in road conditions causing water-splash.A commercially-available fender pole or an antenna for a radio transmitter is
installed to the vehicle.
The vehicle is moving towards a tall or square curbstone, or a steep grade.An obstruction is too close to the sensor.The vehicle is moving towards an uneven wall or stairs.There are multiple obstructions.The vehicle is driven in a place with low ceilings.Obstructions under the bumper cannot be detected. Obstructions which are
lower than the sensor or thin may not be detected even though they were
detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or polesThings which absorb sonic waves easily such as cotton or snowAngular shaped objectsVery tall objects, and those which are wide at the topSmall, short objectsAlways have the system inspected at an Authorized Mazda Dealer if any shock is
applied to the bumpers, even in a minor accident. If the sensors are deviated, they
cannot detect obstructions.
The system may have a malfunction if a sound is not activated or the detection
indication is not displayed even when th e parking sensor OFF switch is pressed
and the parking sensor is operable. Have your vehicle inspected by an Authorized
Mazda Dealer.
The system may have a malfunction if th e indicator light does not turn on even
when the parking sensor OFF switch is turned on. Have your vehicle inspected by
an Authorized Mazda Dealer.
The system may have a malfunction if a message indicating a system malfunction is
displayed. Have your vehicle inspected by an Authorized Mazda Dealer.
A message may be displayed even when the ambient temperature is extremely
cold, or mud, ice, or snow adheres to the sensor area. Remove any foreign matter
from the sensor area.
When installing a trailer hitch, consult an Authorized Mazda Dealer.If a Mazda genuine trailer hitch is used, th e rear side of the parking sensor system

▼Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Flashing)
If there is a problem with the TPMS or
the voltage of a tire pressure sensor
decreases, the TPMS warning light
flashes and a message is displayed on
the multi-information display. Have
your vehicle inspected by an
Authorized Mazda Dealer.
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or flashes:
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 brakes to lower the
vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive 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.
▼ KEY Warning Indication/Warning
Light (Red)
“Keyless Entry System Malfunction.
Have the Vehicle Inspected” is
displayed
This message is displayed if the
advanced keyless entry & push button
start system has a problem.
Contact an Authorized Mazda Dealer.
CAUTION
If the message is indicated, or the push
button start indicator light (amber)
flashes, the engine may not start. If the
engine cannot be started, try starting it
using the emergency operation for
starting the engine, and have the
vehicle inspected at an Authorized
Mazda Dealer as soon as possible.
Refer to Emergency Operation for
Starting the Engine on page 4-9.
“Key Not Detected” is displayed
If the presence of the key cannot be
detected (dead battery, battery
malfunction, no key), it is displayed
when the driver attempts to start the
engine (push button start operation,
brake pedal depression).
Displayed when it is determined that
a key that was in the vehicle has
been removed from the vehicle. (Key
taken out warning. Other than
IG-OFF).
