Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is about 30 km/h (19 mph ) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is ap propriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the active
driving display is indicated to advise you to keep a safe dista nce from the vehicle ahead.
WA R N I N G
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limite d depending on the type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming vehicles.
NOTE
•The DRSS operates when all of the following conditions are met:
•The ignition is switched ON.
•The DRSS is on.
•The selector lever is in a position other than reverse (R).
•The vehicle speed is 30 km/h or faster (19 mph or faster).
•The objects which activate the system are 4-wheeled vehicles.
•The DRSS may also operate in the presence of motorcycles and bicycles.
•The DRSS may not operate normally under the following conditions:
•The Dynamic Stability Control (DSC) has a malfunction.
•The vehicle ahead is traveling at an extremely slow speed.
•The system does not operate with the following objects:
•Vehicles approaching in the opposite direction.
•Stationary objects (stopped vehicles, obstructions)
▼ Indication on Display
The DRSS operation status is indicated in the active driving di
splay or multi-information
display. Regarding malfunctions, check the vehicle conditions o r have it inspected by an
Authorized Mazda Dealer according to the content of the display ed message.

Rear Cross Traffic Alert (RCTA)*
The 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 alertin g the driver to the presence of
vehicles approaching the rear of the vehicle.
The RCTA system detects vehicles approaching from the left and right sides of the vehicle,
and the rear of the vehicle while the vehicle is being reversed out of a parking space, and
notifies the driver of possible danger using the Blind Spot Mon itoring (BSM) warning
indicator lights and the warning buzzer.
Detection areas
Your vehicle
RCTA operation
1. The RCTA system operates when the selector lever is shifted t o the reverse (R) position.
2. If there is the po ssibility of a collision with an approachin g vehicle, the Blind Spot
Monitoring (BSM) warning indicator lights flashes and the warni ng beep is activated
simultaneously.

The RCTA warning indication in the rearview monitor also synchronizes with the Blind
Spot Monitoring (BSM) warning ind icator light on the door mirrors.
WA R N I N G
Always check the surrounding area visually before actually putting the vehicle in reverse:
The system is only designed to assist you in ch ecking for vehicles at the rear when putting the
vehicle in reverse. Due to certain limitations wi th the operation of this system, the Blind Spot
Monitoring (BSM) warning indicator lights may not
flash 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 Authorized Mazda Dealer as
soon as possible.
•Some problem with the system including the Blind Spot Monitoring (BSM) warning
indicator lights has occurred.
•A large deviation in the installation position of a radar sensor (rear) on the vehicle has
occurred.
•There is a large accumulation of snow or ice on the rear bumper near a radar sensor
(rear).
•Driving on snow-covered roads for long periods.
•The temperature near the radar sensors becomes extremely hot due to driving for long
periods on slopes during the summer.

•The battery voltage has decreased.
•Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
•The vehicle speed when reversing is about 15 km/h (9 mph) or faster.
•The radar sensor (rear) detection area is obstructed by a nearby wall or parked vehicle.
(Reverse the vehicle to a position where the radar sensor detection area is no longer
obstructed.)
Your vehicle
•A vehicle is approaching directly from the rear of your vehicle.
Your vehicle
•The vehicle is parked on a slant.
Your vehicle
•Directly after the Blind Spot Monitoring (BSM) system becomes operable using the
personalization feature.
•Radio wave interference from a radar sensor equipped on a nearby parked vehicle.
•In the following cases, it may be difficult to view the illumination/flashing of the Blind
Spot Monitoring (BSM) warning indicator lights equipped on the door mirrors.
•Snow or ice adheres to the door mirrors.
•The front door glass is fogged or covered in snow, frost or dirt.
•Turn off the RCTA system while pulling a trailer or while an accessory such as a bicycle
carrier is installed to the rear of the vehic le. Otherwise, the radio waves emitted by the
radar will be blocked causing the system to not operate normally.

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is to o low in one or more tires, 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 4-32.
Refer to Tire Inflation Pressu re Warning Beep on page 7-50.

The tire pressure sensors installed on each wheel send tire pre ssure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and con dition of all four tires
regularly.
