▼Rear Side Radar Sensor
Your vehicle is equipped with rear side
radar sensor. The following systems
also use the rear side radar sensor.
Blind Spot Monitoring (BSM)Rear Cross Traffic Alert (RCTA)Smart Brake Support (SBS) reverse
drive detection
The rear side radar sensors emit radio
waves and detect the radio waves
reflected off a vehicle approaching
from the rear or an obstruction.
1. Rear side radar sensor

The rear side radar sensors are installed
inside the rear bumper, one on each
side.
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.
CAUTION
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

“Mismatched Tire Diameters. Vehicle
Now in Front Wheel Drive” is
displayed/When the light is turned on
The indication is displayed/the light
turns on under the following
conditions. Inspect the tire sizes or tire
pressures on all 4 wheels. Contact an
Authorized Mazda Dealer if the
indication remains on or the warning
light remains illuminated.
When any of the tire diameter isdifferent.
When any of the tire pressure is
incorrect.
▼ TCS/DSC Indication/Indicator
Light (Turns on)
If the light stays on, the TCS, DSC or
the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
▼Air Bag/Front Seat Belt
Pretensioner System Warning
Indication/Warning Light
A system malfunction is indicated if the
warning light constantly
flashes,
constantly illuminates or does not
illuminate at all when the ignition is
switched ON. If any of these occur,
consult an Authorized Mazda Dealer
as soon as possible. The system may
not operate in an accident.
WARNING
Never tamper with the air bag/
pretensioner systems and always have
an Authorized Mazda Dealer perform
all servicing and repairs:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally
activate or become disabled causing
serious injury or death.
▼ 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.
