CAUTION
Heed the following cautions to assure the correct operation of the Forward Sensing
Camera (FSC).
 
 Do not remove the Forward Sensing Camera (FSC) cover. 
 Do not place objects on the instrument panel which refl ect light. 
 Do not apply accessories, stickers or fi lm to the windscreen near the Forward Sensing
Camera (FSC). If there are objects in front of the Forward Sensing Camera (FSC) lens,
even a transparent sticker, they will cause the system to not operate correctly.
  Always keep the windscreen glass around the camera clean by removing dirt or
fogging. Use the windscreen defroster to remove fogging on the windscreen.
  When cleaning the windscreen, do not allow glass cleaners or similar cleaning agent to
get on the Forward Sensing Camera (FSC) lens. In addition, do not touch the Forward
Sensing Camera (FSC) lens.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning the interior side of the windscreen around the Forward Sensing Camera
(FSC).
  Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get
dirty. Also, do no take the camera apart. Otherwise, it could result in damage or
malfunction.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer before
performing repairs around the Forward Sensing Camera (FSC).
  The Forward Sensing Camera (FSC) is installed to the windscreen. Consult an expert
repairer, we recommend an Authorised Mazda Repairer for windscreen repair and
replacement.
  When performing repairs around the rearview mirror, consult an expert repairer, we
recommend an Authorised Mazda Repairer.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning of the Forward Sensing Camera (FSC) lens.
  Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area
around it. If strong force is applied, stop using the Lane Departure Warning System
(LDWS) and the High Beam Control System (HBC), and consult an expert repairer,
we recommend an Authorised Mazda Repairer.

*Some models.4–150
When Driving
i-ACTIVSENSE
Radar Sensor (Front) *
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
 


 Smart Brake Support (SBS)



 Mazda Radar Cruise Control (MRCC)



 Distance Recognition Support System (DRSS)
The radar sensor (front) functions by detecting the radio waves refl ected off a vehicle ahead
or an obstruction sent from the radar sensor (front).
The radar sensor (front) is mounted behind the front emblem.
Radar sensor (front)
If the Smart Brake Support (SBS) warning light (amber) is illuminated, the area around the
radar sensor (front) may be dirty. Refer to “Warning Guidance” in the centre display (Type
B audio).
Refer to If a Warning Light Turns On or Flashes on page 7-32 .

When Driving
i-ACTIVSENSE
NOTE
  In the following cases, the radar sensor (front) may not be able to detect vehicles ahead
or obstructions.
 


 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
tyres and onto your windscreen.
 


 The boot/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. 

 In the following cases, the radar sensor (front) may detect vehicles in the opposite
lane or surrounding obstructions, or it 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 tyres of the same specifi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use
tyres with signifi cantly different wear patterns or tyre pressures on the same vehicle.
(Including the temporary spare tyre)
  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, Smart Brake Support/Smart City Brake Support (SBS/
SCBS) warning light (amber) temporarily illuminates, however, this does not indicate
a problem.

the cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.
NOTE

system status before it was turned off is
maintained. For example, if the ignition
is switched OFF with the cruise control
system operable, the system will be
operable when the ignition is switched
ON the next time.

  On a steep grade, the vehicle may
momentarily slow down while
ascending, or speed up while
descending.
NOTE
  Cruise control will cancel if the
vehicle speed decreases below
21 km/h (13 mph) when cruise is
activated, such as when climbing a
steep grade.
  Cruise control may cancel at about
15 km/h (9 mph) below the preset
speed (such as may happen when
climbing a long, steep grade).
To Increase Cruising Speed
Follow either of these procedures.
To increase speed using cruise control
switch
Press the SET
switch and hold it. Your
vehicle will accelerate. Release the switch
at the speed you want.
Press the SET
switch and release it

When Driving
Cruise Control
NOTE
Accelerate if you want to speed up
temporarily when the cruise control is
on. Greater speed will not interfere with
or change the set speed. Take your foot
off the accelerator to return to the set
speed.
To Decrease Cruising Speed
Press the SET switch and hold it. The
vehicle will gradually slow.
Release the switch at the speed you want.
Press the SET
switch and release it
immediately to adjust the preset speed.
Multiple operations will decrease the
preset speed according to the number of
times it is operated.
Decreasing speed with a single SET
switch operation
Meter display for vehicle speed indicated
in km/h: 1 km/h (0.6 mph)
Meter display for vehicle speed indicated
in mph: 1 mph (1.6 km/h)
To Resume Cruising Speed at
More Than 25 km/h (16 mph)
If some other method besides the OFF
switch was used to cancel cruising speed
(such as applying the brake pedal) and the
system is still activated, the most recent
set speed will automatically resume when
the RESUME switch is pressed.
If vehicle speed is below 25 km/h (16
mph), increase the vehicle speed up to
25 km/h (16 mph) or more and press the
RESUME switch.
To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
 


 Slightly depress the brake pedal.



(Manual transaxle)
 Depress the clutch pedal.



 Press the CANCEL switch.
If the RESUME switch is pressed when
the vehicle speed is 25 km/h (16 mph) or
higher, the system reverts to the previously
set speed.
NOTE
  If any of the following conditions
occur, the cruise control system is
temporarily cancelled.
 


 The parking brake is applied.



(Vehicles with adjustable speed
limiter)
  The ON/OFF switch for the
adjustable speed limiter is pressed.
 


(Automatic transaxle)
 The selector lever is in the P or N
position.
 


(Manual transaxle)
 The shift lever is in the neutral
position.
 
 When the cruise control system is
temporarily cancelled by even one of
the applicable cancel conditions, the
speed cannot be re-set.
 (Automatic transaxle) The cruise control cannot be
cancelled while driving in manual
mode (selector lever shifted from
D to M position). Therefore, engine
braking will not be applied even
if the transaxle is shifted down
to a lower gear. If deceleration is
required, lower the set speed or
depress the brake pedal.
