Do not rely completely on the Smart City Brake Support (SCBS) system:
The Smart City Brake Support (SCBS) system is only designed to reduce damage in the
event of a collision. Over reliance on the system leading to the accelerator pedal or
brake pedal being mistakenly operated could result in an accident.
The Smart City Brake Support (SCBS) is a system which operates in response to a
vehicle ahead. The system may not be able to detect or react to two-wheeled vehicles
or pedestrians.
The laser sensor (front) for the Smart City Brake Support (SCBS) system is installed near
the rearview mirror. To assure the correct operation of the Smart City Brake Support
(SCBS), heed the following cautions.
Do not apply stickers to the surface of the windshield near the laser sensor (front)
(including transparent stickers). Otherwise, the laser sensor (front) may not be able
to detect vehicles ahead which could result in an accident.
Do not apply coating agent to the windshield. Otherwise, the laser sensor (front)
may not be able to detect vehicles or obstructions in front which could result in an
accident.
Do not disassemble the laser sensor (front).
If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor
(front), stop using the Smart City Brake Support (SCBS) 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 on the windshield near the laser sensor
(front), the system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping the Smart City Brake Support (SCBS) System Operation on page
4-132 .
When replacing the windshield wipers or windshield, consult an Authorized Mazda
Dealer.
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 Smart City Brake Support (SCBS) system not
operating normally or mistakenly operating, which could cause a serious accident.
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation when
the vehicle is running on a chassis roller or being towed.
Refer to the Stopping the Smart City Brake Support (SCBS) System Operation on page
4-132 on how to turn off the Smart City Brake Support (SCBS) system.

NOTE
In the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally.
The height of the vehicle ahead is low.
You drive your vehicle at the same speed as the vehicle ahead.
Headlights are not turned on during the night or when going through a tunnel.
In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly.
When driving next to walls with no patterning (including fences and longitudinally
striped walls).
The taillights of the vehicle ahead are turned off.
A vehicle is outside the illumination range of the headlights.
The vehicle is making a sharp turn, or ascending or descending a steep slope.
Entering or exiting a tunnel.
Heavy luggage is loaded causing the vehicle to tilt.
Strong light is shone at the front of the vehicle (back light or high-beam light from on-
coming vehicles).
There are many light emitters on the vehicle ahead.
When the vehicle ahead is not equipped with taillights or the taillights are turned off at
nighttime.
The vehicle ahead has a special shape. For example, a vehicle towing a trailer house
or a boat, or a vehicle carrier carrying a vehicle with its front pointed rearward.

NOTE
Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not refl ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for refl ecting radio waves.
Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
Ice, snow, or soiling is on the front surface of the front emblem.
During inclement weather such as rain, snow, or sand storms.
When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
Narrow lane roads due to road construction or lane closures.
The vehicle ahead enters the radar sensor's blind spot.
The vehicle ahead is running abnormally due to accident or vehicle damage.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specifi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with signifi cantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly.
When driving on roads with little traffi c and few vehicles ahead or obstructions for
the radar sensor (front) to detect, “Front Radar Sensor Blocked” may be temporarily
displayed, however, this does not indicate a problem.
