2021 MAZDA MODEL MX-5 MIATA RF warning

Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detec ts a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the bra ke control (Smart City Brake
Support (SCBS) brake) when the system determines that a collisi on is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/ h (2 to 18 mph). It may also
be possible to avoid a collision if the relative s peed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to assist. (Brake Ass ist (Smart City Brake Support
(SCBS) brake assist))

WARNING
Do not rely completely on the SCBS system:
 The SCBS system is only designed to reduce da mage in the event of a collision. Over reliance
on the system leading to the accelerator pe dal or brake pedal being mistakenly operated
could result in an accident.
 The SCBS is a system which operates in respon se to a vehicle ahead. The system may not be
able to detect or react to 2- wheeled vehicles or pedestrians.

Forward Sensing Camera (FSC)*
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near t he rearview mirror and used by the following systems.
High Beam Control System (HBC)
Lane Departure Warning System (LDWS)
Traffic Sign Recognition System (TSR)
Smart City Brake Support (SCBS)
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
traveling at night and detects traffic lanes. The distance in w hich the Forward Sensing
Camera (FSC) can detect objects varies depending on the surroun ding conditions.
WARNING
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly detect
vehicles ahead. This will result in the system not operating normally or mistakenly operating,
which could cause a serious accident.
CAUTION
 Do not apply accessories, stickers or film to the windshield near the Forward Sensing
Camera (FSC).
If the area in front of the Forward Sensing Came ra (FSC) lens is obstructed, it will cause the
system to not operate correctly. Consequently, each system may not operate normally
which could lead to an unexpected accident.
 Do not disassemble or modify th e Forward Sensing Camera (FSC).
Disassembly or modification of the Forward Sensing Camera (FSC) will cause a malfunction
or mistaken operation. Consequently, each sy stem may not operate normally which could
lead to an unexpected accident.

Heed the following cautions to assure the correct operation of the Forward Sensing Camera
(FSC).
 Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty.
 Do not remove the Forward Sensing Camera (FSC) cover.
 Do not place objects on the dashboard which reflect light.
 Always keep the windshield glass around the camera clean by removing dirt or fogging.
Use the windshield defroster to remove fogging on the windshield.
 Consult an Authorized Mazda Dealer regardi ng cleaning the interior side of the
windshield around the Forw ard Sensing Camera (FSC).
 Consult an Authorized Mazda Dealer before performing repairs around the Forward
Sensing Camera (FSC).
 The Forward Sensing Camera (FSC) is installe d to the windshield. Consult an Authorized
Mazda Dealer for windshield repair and replacement.
 When cleaning the wind shield, do not allow glass cleaners or similar cleaning fluids to
get on the Forward Sensing Camera (FSC) le ns. In addition, do not touch the Forward
Sensing Camera (FSC) lens.
 When performing repairs around the rearv iew mirror, consult an Authorized Mazda
Dealer.
 Consult an Authorized Mazda Dealer regarding cleaning of the camera lens.
 Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area around
it. If the Forward Sensing Camera (FSC) is severely hit or if there are cracks or damage
caused by flying gravel or debris in the area around it, stop using the following systems
and consult an Authorized Mazda Dealer.
 High Beam Control System (HBC)
 Lane Departure Warning System (LDWS)
 Traffic Sign Recognition System (TSR)
 Smart City Brake Support (SCBS)
 The direction in which the Forward Sensing Camera (FSC) is pointed has been finely
adjusted. Do not change the installation posi tion of the Forward Sensing Camera (FSC) or
remove it. Otherwise, it could result in damage or malfunction.
 Always use tires for all wheels that are of the specified size, and the same manufacturer,
brand, and tread pattern. In addition, do no t use tires with significantly different wear
patterns on the same vehicle as the system may not operate normally.
 The Forward Sensing Camera (FSC) includes a function for detecting a soiled windshield
and informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windshield. In such cases, the system cannot accurately
determine a vehicle ahead and may not be able to operate normally. Always drive carefully
and pay attention to the road ahead.

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 Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-36.
Refer to Taking Action on page 7-40.
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.
