2019 MAZDA MODEL 3 HATCHBACK engine

To assure the correct operation of the
SBS-RC, heed the following cautions.
Do not apply a sticker to a rear radar and
rear camera. Otherwise, the rear radar
and rear camera may not be able to
detect vehicles or obstructions which
could result in an accident.
 Do not disassemble a rear radar and rear
camera.
 If cracks or damage caused by flying
gravel or debris is visible around a rear
radar and rear camera, stop using the
SBS-RC system immediately and have
your vehicle inspected by an Authorized
Mazda Dealer. If the vehicle continues to
be driven with cracks or scratch marks
left around an ultrasonic sensor, the
system may operate unnecessarily and
cause an unexpected accident.
Refer to Stopping the Smart Brake
Support [Rear Crossing] (SBS-RC) System
Operation on page 4-164.
 Consult an Authorized Mazda Dealer for
rear bumper replacement.
Do not modify the suspension:
If the vehicle height or inclination is
changed, the SBS-RC system may not
operate correctly because it cannot detect
obstructions correctly.Do not apply a strong force to a rear radar
and rear camera:
When washing the vehicle, do not spray
highly pressurized water against a rear
radar and rear camera, or rub it strongly. In
addition, do not hit the rear bumper
forcefully when loading and unloading
cargo Otherwise, the sensors may not
detect obstructions correctly which could
cause the SBS-RC system to not operate
normally, or it could operate unnecessarily.

CAUTION
Do not install any accessories within the detection ranges of the sensors. It may
affect the
system operation.
 Depending on the type of obstruction and th e surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
NOTE
The system may not operate norma lly under the following conditions:
Mud, ice, or snow is adhering to the sensor area (Returns to normal operation when
removed).
The sensor area is frozen (Returns to normal operation when the ice is thawed).
The sensor is covered by a hand.
The sensor is excessively shocked.
The vehicle is excessively tilted.
Under extremely hot or cold weather conditions.
The vehicle is driven on bumps, inclines, gravel, grating, or grass covered roads.

Operating Tips
▼Operating Tips
Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
switch on for a long
period of time with
the ignition switched ON when the
engine is not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
Use the climate control system to defog
the windows and dehumidify the air.
The recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
(With A/C switch)
Run the air conditioner about 10
minutes at least once a month to keep
internal parts lubricated.
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If the
wrong type of refrigerant is used, it
could result in a ser ious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.
