When Driving
i-ACTIVSENSE
NOTE
  The Mazda Radar Cruise Control (MRCC) system operates when all of the following
conditions are met.
 


 The vehicle speed is as follows:
(European models)
 About 30 km/h (19 mph) to 200 km/h (124 mph)
(Except European models)
 About 30 km/h (19 mph) to 145 km/h (90 mph)



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



 The parking brake is not applied.



 The Dynamic Stability Control (DSC) is operating normally.
(Manual transaxle)




 The shift lever is in a position other than reverse (R) or neutral (N).



 The clutch pedal is not depressed.

(Automatic transaxle)



 The selector lever is in the drive (D) position or manual (M) position (manual
mode).
 
 In the following cases, the warnings may not activate even if your vehicle starts
closing in on the vehicle ahead.
 


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



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



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


 Another vehicle cuts into the driving lane. 

 The following are not detected as physical objects.




 Vehicles approaching in the opposite direction



 Pedestrians



 Stationary objects (stopped vehicles, obstructions) 

 If a vehicle ahead is travelling at an extremely low speed, the system may not detect it
correctly.
  During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
  Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in
which the close proximity warnings are frequently activated.
  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.

NOTE
  While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel
even if the selector lever (automatic transaxle)/shift lever (manual transaxle) is
operated and any intended engine braking will not occur. If deceleration is required,
lower the vehicle speed setting or depress the brake pedal.
  The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating, however, they may not be illuminated while the
vehicle is on a down slope at the set vehicle speed or travelling at a constant speed and
following a vehicle ahead.
  The Mazda Radar Cruise Control (MRCC) warning light (amber) turns on when the
system has a malfunction.
 Refer to Warning/Indicator Lights on page 4-36 .
Mazda Radar Cruise Control (MRCC) Display Indication
The setting status and operation conditions of the Mazda Radar Cruise Control (MRCC)
system are indicated in the active driving display.

Close Proximity Warning
If your vehicle rapidly closes in on the vehicle ahead because the vehicle applies the brakes
suddenly while you are travelling in headway control, the warning sound activates and
the brake warning is indicated in the display. Always verify the safety of the surrounding
area and depress the brake pedal while keeping a safer distance from the vehicle ahead.
Additionally, always keep a safer distance from the vehicles behind you.

NOTE
For example, the set vehicle speed is
changed by pressing the SET switch
four times as follows:
(European models)
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
(Except European models)
The vehicle speed accelerates or
decelerates by 20 km/h (20 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
operated, the system returns to the set
speed when you release your foot from the
accelerator pedal.
CAUTION
The warnings and brake control do not
operate while the accelerator pedal is
depressed.
NOTE
  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 speed. Check the set
vehicle speed by viewing the set
vehicle speed display in the active
driving display.
  When depressing the accelerator
pedal, the inter-vehicle distance
display in the active driving display
changes to the white-line display.
  The minimum settable speed is 30
km/h (19 mph). If the set vehicle
speed reaches 30 km/h (19 mph)
using the switch operation, constant
speed travel is maintained at about
30 km/h (19 mph) even if the SET
switch is pressed. The Mazda Radar
Cruise Control (MRCC) system is
not cancelled.
To Deactivate
With adjustable speed limiter
The Mazda Radar Cruise Control (MRCC)
is cancelled when the ON/OFF switch is
pressed.
Without adjustable speed limiter
The Mazda Radar Cruise Control (MRCC)
is cancelled when the OFF switch is
pressed.

NOTE

 The Mazda Radar Cruise Control
(MRCC) system may be cancelled
during rain, fog, snow or other
inclement weather conditions, or the
front surface of the radiator grille is
dirty.
  If you have temporarily cancelled
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.
  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.
Shift-up/Shift-down Request
Display (Manual Transaxle)

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))

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 tyre 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:
 
 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 windscreen 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 windscreen. 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 expert repairer, we recommend
an Authorised Mazda Repairer. If the vehicle continues to be driven with cracks or
scratch marks left on the windscreen 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 4-143 .
 

 
 When replacing the windscreen wipers or windscreen, consult an expert repairer,
we recommend an Authorised Mazda Repairer.
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.
