*Some models.
Smart Brake Support (SBS) *
Smart Brake Support (SBS) is a system which alerts the driver of a possible collision using
an indicator and warning sound in the instrument cluster while the vehicle is being driven at
about 15 km/h or faster (10 mph or faster) and the system's radar sensor (front) determines
that your vehicle may hit a vehicle ahead. Furthermore, if the radar sensor (front) determines
that a collision is unavoidable, the automatic brake control is performed to reduce damage in
the event of a collision.
In addition, when the driver depresses the brake pedal, the brakes operate more quickly to
assist the driver.
WARNING
Do not rely completely on the Smart Brake Support (SBS) system and always drive
carefully:
The Smart Brake Support (SBS) is designed to reduce damage in the event of a collision,
not avoid an accident. The ability to detect an obstruction is limited depending on the
obstruction, weather conditions, or traffi c conditions. Therefore, if the accelerator pedal
or brake pedal is mistakenly operated it could result in 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.
CAUTION
If the vehicle is towed or you are towing something, switch the Smart Brake Support (SBS)
system off to prevent a mistaken operation.

The Smart Brake Support (SBS) system operates when all of the following conditions are
met:
The ignition is switched ON.
The Smart Brake Support (SBS) system is on.
The vehicle speed is about 15 km/h or faster (10 mph or faster).
The relative speed between your vehicle and the vehicle ahead is about 15 km/h or
faster (10 mph or faster).
The Dynamic Stability Control (DSC) is not operating.
The Smart Brake Support (SBS) system may not operate under the following conditions:
If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.
The vehicle is driven at the same speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
The turn signal is being used.
When the vehicle ahead is not equipped with taillights or the taillights are turned off.
When warnings and messages, such as a dirty windshield, related to the Forward
Sensing Camera (FSC)/laser sensor (front) are being displayed in the multi-
information display.
Although the objects which activate the system are four-wheeled vehicles, the radar
sensor (front) could detect the following objects, determine them to be an obstruction, and
operate the Smart Brake Support (SBS) system.
Objects on the road at the entrance to a curve (including guardrails and snow banks).
A vehicle appears in the opposite lane while cornering or rounding a curve.
When crossing a narrow bridge.
When passing under a low gate or through a tunnel or narrow gate.
When entering an underground parking area.
Metal objects, bumps, or protruding objects on the road.
If you suddenly come close to a vehicle ahead.
When driving in areas where there is high grass or forage.
Two-wheeled vehicles such as motorbikes or bicycles.
Pedestrians or non-metallic objects such as standing trees.
When the system operates, the user is notifi ed by the multi-information display.
The Smart Brake Support (SBS) warning indication (amber) turns on when the system has

*Some models.
Radar Sensor (Front) *
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
Distance Recognition Support System (DRSS)
Mazda Radar Cruise Control (MRCC)
Smart Brake Support (SBS)
The radar sensor (front) functions by detecting the radio waves refl ected off a vehicle ahead
or an obstruction sent from the radar sensor.
The radar sensor (front) is mounted behind the front emblem.
Radar sensor (front)
If “Front Radar Sensor Blocked” is displayed in the multi-information display of the
instrument cluster, clean the area around the radar sensor (front).

*Some models.
Laser Sensor (Front) *
Your vehicle is equipped with a laser sensor (front). The laser sensor (front) is positioned
near the rearview mirror and used by the following systems.
Smart City Brake Support (SCBS)
Smart Brake Support (SBS)
CAUTION
Heed the following precautions to assure correct operation of the system.
Keep the windshield clean at all times.
Do not apply stickers to the surface of the windshield (including transparent stickers).
If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor
(front), stop using the system immediately and have your vehicle inspected by an
Authorized Mazda Dealer.
Refer to the Personalization Features on page 9-11 on how to turn off the system.
Do not apply a coating agent to the windshield.
When replacing the windshield wipers or windshield, consult an Authorized Mazda
Dealer.
Never remove the sensor.
A removed sensor will not meet the conditions for a class 1M laser under the IEC
60825-1 specifi cation and therefore eye safety cannot be assured.
Do not peer into the sensor using optical instruments with a magnifi cation function
such as magnifying glasses, and microscopic and objective lenses within a distance of
100 mm (3.94 in) from the sensor.

When Driving
Parking Sensor System
The system may not operate normally 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, or grass covered roads.
Anything which generates ultrasound is near the vehicle, such as another vehicle's
horn, the engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors.
The vehicle is driven in heavy rain or in road conditions causing water-splash.
A commercially-available fender pole or an antenna for a radio transmitter is installed
to the vehicle.
The vehicle is moving towards a tall or square curbstone.
An obstruction is too close to the sensor.
Obstructions under the bumper may not be detected. Obstructions that are lower than the
bumper or thin which may have been initially detected but are no longer detected as the
vehicle approaches more closely.
The following types of obstructions may not be detected:
Thin objects such as wire or rope
Things which absorb sonic waves easily such as cotton or snow
Angular shaped objects
Very tall objects, and those which are wide at the top
Small, short objects
Always have the system inspected at an Authorized Mazda Dealer if any shock is applied
to the bumpers, even in a minor accident. If the sensors are deviated, they cannot detect
obstructions.
The system may have a malfunction if the beep does not operate or the indicator
light does not illuminate when the park assist sensors switch is turned on. Consult an
Authorized Mazda Dealer.
The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the indicator light fl ashes. Consult an Authorized Mazda Dealer.
The beeper which indicates a system malfunction may not be heard if the ambient
temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove
any foreign material from the sensor area.
When installing a trailer hitch, consult an Authorized Mazda Dealer.

(SBS/SCBS) Warning
Light
* The light turns on if the windshield or
the radar sensor are dirty, or there is a
malfunction in the system. Verify the reason why the warning light
is illuminated on the center display.
If the reason why the warning light is
illuminated is due to a dirty windshield,
clean the windshield.
If the warning light is illuminated
because of a dirty radar sensor, clean the
front emblem.
For any other reasons, have the vehicle
inspected at an Authorized Mazda
Dealer.
Low Fuel Warning
Indication/Warning Light The light turns on when the remaining fuel
is about 9.0 L (2.3 US gal, 1.9 Imp gal). NOTE
The light illumination timing may vary
because fuel inside the fuel tank moves
around according to the driving conditions
and the vehicle posture.
Add fuel.
Check Fuel Cap Warning
Indication/Warning Light
* If the check fuel cap warning light
illuminates while driving, the fuel-fi ller cap
may not be installed properly. Stop the engine and reinstall the fuel-
fi ller cap.
Refer to Fuel-Filler Cap on page 3-31
