NOTE
 


y The Mazda Radar Cruise Control (MRCC) system operates when all of the following
conditions are met.
 


y The vehicle speed is about 30 km/h (19 mph) to 145 km/h (90 mph).



y The Mazda Radar Cruise Control (MRCC) system is turned on.



y The parking brake is not applied.



y The Smart Brake Support (SBS) is not malfunctioning.



y The Dynamic Stability Control (DSC) is operating normally.



y The selector lever is in the drive (D) position or manual (M) position (manual mode).




y In the following cases, the warnings may not activate even if your vehicle starts closing in
on the vehicle ahead.
 


y You are driving at the same speed as the vehicle ahead.



y Directly after the Mazda Radar Cruise Control (MRCC) system has been set.



y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 


y Another vehicle cuts into the driving lane.




y The following are not detected as physical objects.




y Vehicles approaching in the opposite direction



y Pedestrians



y Stationary objects (stopped vehicles, obstructions)




y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 


y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 


y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 


y During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
 


y While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel
even if the selector lever is operated and any intended engine braking will not occur. If
deceleration is required, lower the vehicle speed setting or depress the brake pedal.
 


y The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating.

How to Set the Distance Between
Vehicles During Headway Control
The distance between vehicles is set to a
shorter distance each time the
switch is
pressed. The distance between vehicles is
set to a longer distance by pressing the
switch. The distance-between-vehicles can
be set to 4 levels; Long, medium, short,
and extremely short distance.
Distance-between-
vehicles guideline
(at 80 km/h (50 mph)
vehicle speed) Indication on display
Long (about 50 m (164
ft))
Medium (about 40 m
(131 ft))
Short (about 30 m (98
ft))
Extremely short (about
25 m (82 ft))
NOTE
 


y The distance between vehicles differs
depending on the vehicle speed, and the
slower the vehicle speed, the shorter the
distance.
 


y When the ignition is switched to ACC
or OFF and then the engine is started
again, the system automatically sets
the distance between vehicles to the
previous setting.
Changing the Set Vehicle Speed
Changing the set vehicle speed using the
SET switch

NOTE
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To accelerate using the accelerator
pedal
Depress the accelerator pedal and press
and release the SET
or SET switch at
the desired speed. If a switch cannot be

NOTE
 


y When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle

NOTE
 


y The Mazda Radar Cruise Control
(MRCC) system may be canceled during
rain, fog, snow or other inclement
weather conditions, or the front surface
of the radiator grille is dirty.
 


y If you have temporarily canceled the
Mazda Radar Cruise Control (MRCC),
you can return to your previously set
speed by pressing the RES switch and
after all of the operation conditions
have been met.
 


y If the OFF switch is pressed to cancel
the Mazda Radar Cruise Control
(MRCC), the system does not return to
the previously set speed even if the RES
switch is pressed.
Cruise Control Function
While this function is operating, the
headway control operation is canceled and
only the cruise control function operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
 


¾ Roads with sharp curves and where
vehicle traffi c is heavy and there is
insuffi cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
 


¾ Steep down slopes (Set speed may
be exceeded because suffi cient
engine braking cannot be applied)
 


¾ Slippery roads such as ice or snow-
bound roads (Tires could spin
causing you to lose vehicle control)

Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is canceled and the
system is switched to only the cruise
control function. Depress the brake
pedal to decelerate according to the
surrounding conditions while keeping
a safer distance from the vehicle ahead
and always driving carefully.

Switching to cruise control function
When the ON switch is pressed
continuously for about 2 seconds while
the Mazda Radar Cruise Control (MRCC)
system is turned on, the system is switched
to the cruise control function.
The Mazda Radar Cruise Control (MRCC)
indicator light (green) in the instrument
cluster turns off and the cruise control
indication is displayed in the active
driving display.
WARNING
Always turn off the cruise control
function when it is not in use:
Leaving the cruise control function
turned on when it is not in use
is dangerous as it could operate
unexpectedly, resulting in an accident.
How to set the speed
Adjust the system to the desired vehicle
speed using the accelerator pedal.
Cruise control function begins when the
SET
or SET switch is pressed.
NOTE
 


y The system may not be able to maintain
the set speed constantly depending on
driving conditions such as steep up or
down slopes.
 


y The speed will continue increasing
while the SET
switch is pressed and
held. The speed will continue
decreasing while the SET
switch is
pressed and held.
How to increase the set speed
The set speed can be increased using the
following operations:
To increase speed using the SET
switch
Press and hold the SET
switch and
release the switch at the desired speed.
The set speed can be adjusted
incrementally (1 km/h (1 mph)
increments) by pressing the switch and
releasing it immediately. For example, if
the switch is pressed 4 times, the set speed
increases by about 4 km/h (4 mph).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press the
SET
or SET switch at the desired
speed.
If the switch is not operated, the system
returns to the set speed after you release
your foot from the accelerator pedal.
How to Decrease the Set Speed
Press the SET
switch continuously and
release the switch at the desired speed.
The set speed can be adjusted
incrementally (1 km/h (1 mph) increments)

Smart City Brake Support (SCBS) *
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
(front) 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 fi rmly 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.
