running alongside the vehicle.Places where the width between guardrails or
walls on each side of the vehicle narrows.
The walls at the entrance and exits of tunnels,
turnouts.
  A Blind Spot Monitoring (BSM) warning light may À ash or the warning beep may be
activated several times when making a turn at a city intersection.
  Turn off the Blind Spot Monitoring (BSM) while pulling a trailer or while an accessory
such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radar’s
radio waves will be blocked causing the system to not operate normally.

Warning Beep
The Blind Spot Monitoring (BSM) or Rear Cross Traf¿ c Alert (RCTA) system noti¿ es the
driver of the presence of vehicles in adjacent lanes to the rear of your vehicle using the
Blind Spot Monitoring (BSM) warning lights and the warning beep while the systems are
operational.
Blind Spot Monitoring (BSM) warning lights
The Blind Spot Monitoring (BSM) warning lights are equipped on the left and right door
mirrors. The warning lights turn on when a vehicle approaching from the rear in an adjacent

Forward driving (Blind Spot Monitoring (BSM) system operation)
The Blind Spot Monitoring (BSM) system detects vehicles approaching from the rear and
turns on the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors
according to the conditions. Additionally, while a Blind Spot Monitoring (BSM) warning
light is illuminated, if the direction indicator lever is operated to signal a turn in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the Blind Spot
Monitoring (BSM) warning light À ashes.
Reverse driving (Rear Cross Traf¿ c Alert (RCTA) system operation)
The Rear Cross Traf¿ c Alert (RCTA) system detects vehicles approaching from the left and
right of your vehicle and À ashes the Blind Spot Monitoring (BSM) warning lights.
Function for cancelling illumination dimmer
If the Blind Spot Monitoring (BSM) warning lights turn on when the position lights are
turned on, the brightness of the Blind Spot Monitoring (BSM) warning lights is dimmed.
If the Blind Spot Monitoring (BSM) warning lights are dif¿ cult to see due to glare from
surrounding brightness when travelling on snow-covered roads or under foggy conditions,
press the dimmer cancellation button to cancel the dimmer and increase the brightness of
Blind Spot Monitoring (BSM) warning lights when they turn on.
Refer to Instrument Panel Illumination on page 4-28 .

Rear Cross Traf¿ c Alert (RCTA) *
T h e R e a r C r o s s T r a f¿ c Alert (RCTA) system is designed to assist the driver in checking the
area to the rear of the vehicle on both sides while the vehicle is reversing by alerting the
driver to the presence of vehicles approaching the rear of the vehicle.
The Rear Cross Traf¿ c Alert (RCTA) system detects vehicles approaching from the left and
right sides of the vehicle while the vehicle is being reversed out of a parking space, and
noti¿ es the driver of possible danger using the Blind Spot Monitoring (BSM) warning lights
and the warning buzzer.

transmission) or the selector lever (automatic transmission) is shifted to the reverse (R)
position.
2. If there is the possibility of a collision with an approaching vehicle, the Blind
Spot Monitoring (BSM) warning light À ashes and the warning beep is activated
simultaneously.

WARNING
Always check the surrounding area visually before actually putting the vehicle in
reverse:
The system is only designed to assist you in checking for vehicles at the rear when
putting the vehicle in reverse. Due to certain limitations with the operation of this
system, the Blind Spot Monitoring (BSM) warning light may not À ash or it might be
delayed even though a vehicle is behind your vehicle. Always make it your responsibility
as a driver to check the rear.
NOTE
  In the following cases, the Blind Spot Monitoring (BSM) OFF indicator light turns
on and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF
indicator light remains illuminated, have the vehicle inspected at an Authorised Mazda
Dealer as soon as possible.

Tyre Pressure Monitoring System
*Some models.
Tyre Pressure Monitoring System (Vehicle with
Conventional Tyres)
*
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre 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 speci¿ ed
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-143 .
The warning light À ashes when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-42 .

Tyre Pressure Monitoring System
*Some models.
Tyre Pressure Monitoring System (Vehicle with Run-À at
Ty r e s )
*
The Tyre Pressure Monitoring System (TPMS) monitors the pressure for each tyre.
If tyre pressure is too low in one or more tyres, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights on page 4-42 .
Refer to Tyre InÀ ation Pressure Warning Beep on page 7-53 .
The tyre pressure sensors installed on each wheel send tyre pressure data by radio signal to
the receiver unit in the vehicle.
Tyre pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tyre temperatures are also
lower. When the tyre temperature decreases, the air pressure decreases as well. The TPMS
warning light may illuminate more frequently. Visually inspect the tyres daily before
driving, and check tyre pressures monthly with a tyre pressure gauge. When checking tyre
pressures, use of a digital tyre pressure gauge is recommended.
TPMS does not alleviate your need to check the pressure and condition of all four tyres
regularly.
