Radar Sensor
NOTE
 y In the following cases, the radar sensor may not be able to detect vehic\
les ahead or
obstructions.
 y 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.
 y Vehicles ahead with low vehicle height and thus less area for refl ecting radio waves. y Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
 y The trunk/luggage compartment is loaded with heavy objects or the rear passenger
seats are occupied.
 y Ice, snow, or soiling is on the front surface of the front emblem. y During inclement weather such as rain, snow, or sand storms. y When driving near facilities or objects emitting strong radio waves.
 y In the following cases, the radar sensor may detect vehicles in the oppo\
site lane or
surrounding obstructions, or it may not be able to detect vehicles ahead or \
obstructions.
 y The beginning and end of a curve. y Roads with continuous curves. y Narrow lane roads due to road construction or lane closures. y The vehicle ahead enters the radar sensor's blind spot. y The vehicle ahead is running abnormally due to accident or vehicle damag\
e.  y Roads with repeated up and down slopes y Driving on poor roads or unpaved roads. y The distance between your vehicle and the vehicle ahead is extremely short. y A vehicle suddenly comes close such as by cutting into the lane.
 y 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)
 y If the battery power is weak, the system may not operate correctly. y When driving on roads with little traffi c and few vehicles ahead or obstructions for the
radar sensor to detect, Forward Obstruction Warning/Smart City Brake Support (FOW/
SCBS) warning light (amber) temporarily illuminates, however, this does not indicate a
problem.

When Driving
Brake
Smart City Brake Support (SCBS) *
The Smart City Brake Support (SCBS) system is designed to reduce damag\
e in the event
of a collision by operating the brake control (SCBS brake) when the sy\
stem's laser sensor
detects a vehicle ahead and determines that a collision with a vehicle a\
head is unavoidable.
It may also be possible to avoid a collision if the relative speed betwe\
en your vehicle and a
vehicle ahead is less than about 15 km/h (9.3 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 fi\
rmly and quickly to
assist. (Brake Assist (SCBS brake assist))
Laser sensor
WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safe
driving: The Smart City Brake Support (SCBS) system cannot compensate for unsafe and reckless
driving, excessive speed, tailgating (following another vehicle too closely), and driving on
slippery roads such as wet, snowy, and icy roads (reduced tire friction and road contact
because of water on the road surface). You can still have an accident.

When Driving
Mazda Radar Cruise Control (MRCC)
Mazda Radar Cruise Control (MRCC) *
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control *1
according to the vehicle speed using a radar sensor to detect the distan\
ce to a vehicle ahead,
and by presetting the vehicle speed between 30 km/h (19 mph) and 145 k\
m/h (90 mph), the
driver is freed from having to constantly use the accelerator or brake p\
edals.
*1 Headway Control: Control of the distance between your vehicle and the ve\
hicle ahead detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for ex\
ample, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a suffi cient distance between the vehicles.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and ot\
her highways
which do not require a lot of repeated acceleration and deceleration.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully: The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifi cally, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate suffi ciently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which could result in an accident. Always verify the safety of the surrounding area
and depress the brake pedal or accelerator pedal while keeping a safe distance from
vehicles ahead or on-coming vehicles.

When Driving
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) *
Forward Obstruction Warning (FOW) 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
determines that your vehicle may hit a vehicle or obstruction ahead.
WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully: Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. 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 safe
distance from vehicles ahead or on-coming vehicles.
NOTE
 y  The Forward Obstruction Warning (FOW) system operates when all of the following
conditions are met:
 y The ignition is switched ON. y The Forward Obstruction Warning (FOW) system is on. y The vehicle speed is about 15 km/h (10 mph) or faster. y The relative speed between your vehicle and the vehicle or obstruction ahead \
is about
15 km/h (10 mph) — 145 km/h (90 mph).
 y The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
 y If there is the possibility of hitting only a part of a vehicle or obstruction \
ahead. y If the vehicle is accelerated rapidly and it comes close to a vehicle ah\
ead. y The DSC is malfunctioning. y The vehicle is driven at the same speed as the vehicle ahead. y The accelerator pedal is depressed. y The brake pedal is depressed. y The steering wheel is being operated. y The selector lever is being operated. y The turn signal is being used.

If Trouble Arises
Warning/Indicator Lights and Warning Sounds
Signal Warning Action to be taken
Tire
Pressure
Monitoring System
Warning Light
*
When the warning light illuminates, and the
warning beep sound is heard (about 3 seconds),
tire pressure is too low in one or more tires.
WARNING
If the tire pressure monitoring system
warning light illuminates or fl ashes, or the
tire pressure warning beep sound is heard,
decrease vehicle speed immediately and
avoid sudden maneuvering and braking: If the tire pressure monitoring system
warning light illuminates or fl ashes, or the
tire pressure warning beep sound is heard,
it is dangerous to drive the vehicle at high
speeds, or perform sudden maneuvering
or braking. Vehicle drivability could worsen
and result in an accident.
To determine if you have a slow leak or a
fl at, pull over to a safe position where you
can check the visual condition of the tire
and determine if you have enough air to
proceed to a place where air may be added
and the system monitored again by an
Authorized Mazda Dealer or a tire repair
station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken care of
as soon as possible before it develops into
a more serious situation that could lead to
tire failure and a dangerous accident. Inspect the tires and adjust to the specifi
ed
infl ation pressure (page 6-42 ).
NOTE
yPerform tire pressure adjustment when the tires
are cold. Tire pressure will vary according to
the tire temperature, therefore let the vehicle
stand for 1 hour or only drive it 1.6 km (1 mile)
or less before adjusting the tire pressures.
When pressure is adjusted on hot tires to the
cold infl ation pressure, the TPMS warning
light/beep may turn on after the tires cool and
pressure drops below specifi cation.
Also, an illuminated TPMS warning light,
resulting from the tire air pressure dropping
due to cold ambient temperature will remain
illuminated even if the ambient temperature
rises. In this case, it will also be necessary
to adjust the tire air pressures. If the TPMS
warning light illuminates due to a drop in tire
air pressure, make sure to check and adjust the
tire air pressures.
y Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over
time or you have a fl at. However, when you
fi nd one low tire in a set of four-that is an
indication of trouble; you should have someone
drive the vehicle slowly forward so you can
inspect any low tire for cuts and any metal
objects sticking through tread or sidewall. Put
a few drops of water in the valve stem to see if
it bubbles indicating a bad valve. Leaks need
to be addressed by more than simply reinfl ating
the tire as leaks are dangerous — take it to an
Authorized Mazda Dealer.

Warning Light
*
The light turns on if the windshield and 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 (page 7-24 ).
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.
