Mazda Radar Cruise Control (MRCC)í
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 distance to a
vehicle ahead, and by presetting the vehicle speed between 30 km/h (19 mph) and 145
km/h (90 mph), the driver is freed from having to constantly use the accelerator or brake
pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for example,
the vehicle ahead brakes suddenly, a warning sound and a warning indication in the display
are activated simultaneously to alert you to maintain a sufficient distance between the
vehicles.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other 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 specifically, 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 sufficiently 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 safer distance from vehicles ahead or on-coming vehicles.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
ØRoads with sharp curves and where vehicle traffic is heavy and there is insufficient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
ØWhen entering and exiting interchanges, service areas, and parking areas of
highways (If you exit a highway while headway control is in use, the vehicle
ahead will no longer be tracked and your vehicle may accelerate to the set speed).
ØSlippery roads such as ice or snow-bound roads (The tires could spin causing you
to lose vehicle control).
ØLong descending slopes (to maintain distance between vehicles, the system
automatically and continuously applies the brakes which could result in the loss
of brake power).
For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.
CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.

Smart City Brake Support (SCBS)í
The Smart City Brake Support (SCBS) system is designed to reduce damage in the event of
a collision by operating the brake control (SCBS brake) when the system's laser sensor
detects a vehicle ahead and determines that a collision with a vehicle ahead is unavoidable.
It may also be possible to avoid a collision if the relative speed between your vehicle and a
vehicle ahead 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 Assist (SCBS brake assist))
Laser Sensor (Front)
WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safer
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.

Do not rely completely on the Smart City Brake Support (SCBS) system:
ØThe 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.
ØThe 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.
ØThe laser sensor 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.
ØDo not apply stickers to the surface of the windshield near the laser sensor
(including transparent stickers). Otherwise, the laser sensor may not be able to
detect vehicles ahead which could result in an accident.
ØDo not apply coating agent to the windshield. Otherwise, the laser sensor may
not be able to detect vehicles in front which could result in an accident.
ØDo not disassemble the laser sensor.
ØIf cracks or damage caused by flying gravel or debris is visible near the laser
sensor, 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, the system may operate unnecessarily and cause an
unexpected accident.
Refer to Stopping the Smart City Brake Support (SCBS) System Operation on
page 4-130.
ØWhen 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. See the next page on
how to turn off the Smart City Brake Support (SCBS).
Refer to Stopping the Smart City Brake Support (SCBS) System Operation on page
4-130.

CAUTION
ØWhen driving off-road in areas where there is grass or forage, it is recommended
that the Smart City Brake Support (SCBS) system be turned off.
ØAlways use tires for all wheels that are of the specified size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tires with
significantly different wear patterns on the same vehicle as the Smart City Brake
Support (SCBS) system may not operate normally.
ØThe laser sensor 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.
