Radar Sensor (Front) *
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
 


 Mazda Radar Cruise Control (MRCC)



 Distance Recognition Support System (DRSS)



 Smart Brake Support (SBS)
The radar sensor (front) functions by detecting the radio waves reÀ ected off a vehicle ahead
or an obstruction sent from the radar sensor.
The radar sensor (front) is mounted behind the front emblem.

When Driving
i-ACTIVSENSE
NOTE
  Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
 


 The rear surface of a vehicle ahead does not reÀ 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 reÀ 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. 

 Under the following conditions, the radar sensor (front) 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 speci¿ ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use
tyres with signi¿ 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. 
 If the vehicle is driven on a road with little traf¿ c and few vehicles ahead or
obstructions for the radar sensor (front) to detect, the sensor detects that the radar
sensor (front) is dirty and the Smart Brake Support/Smart City Brake Support (SBS/
SCBS) Warning Light (amber) may be temporarily turned on. However, it does not
indicate a malfunction.

When Driving
i-ACTIVSENSE
*Some models.
Laser Sensor *
The Smart City Brake Support (SCBS) laser sensor is installed at the top of the windscreen
near the rearview mirror.



Always keep the surface of the windscreen around the laser sensor clean to assure proper
operation of the Smart City Brake Support (SCBS) system.
WARNING
As there is the possibility of eye damage occurring from the laser, always heed the
following precautions:
 
 Never remove the sensor. 
 A removed sensor will not meet the conditions for a class 1M laser under the IEC
60825-1 speci¿ cation and therefore eye safety cannot be assured.

 Do not peer into the sensor using optical instruments with a magni¿ cation function
such as magnifying glasses, and microscopic and objective lenses within a distance
of 100 mm (3.94 in) from the sensor.

Cruise Control
*Some models.
Cruise Control *
With cruise control, you can set and automatically maintain any speed of more than about
25 km/h (16 mph).
WARNING
Do not use the cruise control under the following conditions:
Using the cruise control under the following conditions is dangerous and could result
in loss of vehicle control.
 
 Hilly terrain 
 Steep inclines 
 Heavy or unsteady traf¿ c 
 Slippery or winding roads 
 Similar restrictions that require inconsistent speed

Cruise main indication (white)
The cruise main indication (white) is
displayed in the instrument cluster when
the cruise control system is activated.


Cruise set indication (white)/indicator
light (green)
The cruise set indication (white) is
displayed in the instrument cluster and the
cruise set indicator light (green) turns on
when a cruising speed has been set.


Activation/Deactivation
With adjustable speed limiter
To activate the system, press the MODE
switch. The cruise main indication (white)
is displayed.
To deactivate the system, press the OFF/
CAN switch.
The cruise main indication (white) turns
off.
NOTE
When the MODE switch is pressed
while the cruise control system is
operating, the cruise control system
switches to the adjustable speed limiter.
Without adjustable speed limiter
To activate the system, press the ON
switch. The cruise main indication (white)
is displayed.
To deactivate the system, press the OFF/
CAN switch.
The cruise main indication (white) turns
off.
WARNING
Always turn off the cruise control
system when it is not in use:
Leaving the cruise control system in an
activation-ready state while the cruise
control is not in use is dangerous as
the cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.

When Driving
Tyre Pressure Monitoring System
*Some models.
Tyre Pressure Monitoring System *
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the speci¿ ed
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-192 .
The warning light À ashes when the system has a malfunction.
Refer to Warning Lights on page 4-38 .

When Driving
Tyre Pressure Monitoring System
NOTE
Because this system detects slight changes in tyre conditions, the timing of the warning
may be faster or slower in the following cases:
 
 The size, manufacturer, or the type of tyres is different from the speci¿ cation. 
 The size, manufacturer, or the type of a tyre is different from the others, or the level of
tyre wear is excessively different between them.
  A run-À at tyre, studless tyre, snow tyre, or tyre chains are used. 
 An emergency tyre is used (The tyre pressure monitoring system warning light may
À ash and then continue illuminating).

 A tyre is repaired using the emergency À at tyre repair kit. 
 The tyre pressure is excessively higher than the speci¿ ed pressure, or the tyre pressure
is suddenly lowered for some reason such as a tyre burst during driving.
  The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle
is stopped), or the drive period is shorter than 5 minutes.
  The vehicle is driven on an extremely rough road or a slippery, icy road. 
 Hard steering and rapid acceleration/deceleration are repeated such as during
aggressive driving on a winding road.
  Load on the vehicle is applied to a tyre such as by loading heavy luggage to one side of
the vehicle.
  System initialization has not been implemented with the speci¿ ed tyre pressure.
Tyre Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
 


 A tyre pressure is adjusted.



 Tyre rotation is performed.



 A tyre or wheel is replaced.



 The battery is replaced or completely
drained.
 


 The tyre pressure monitoring system
warning light is illuminated.

Initialization method

1. Park the car in a safe place and ¿ rmly
apply the parking brake.
2. Let the tyres cool, then adjust the tyre
pressure of all four (4) tyres to the
speci¿ ed pressure indicated on the tyre
pressure label located on the driver's
door frame (door open).
Refer to Tyres on page 9-10 .
3. Switch the ignition ON.

Tyre Pressure Monitoring System
4. Press and hold the tyre pressure
monitoring system set switch and
verify that the tyre pressure monitoring
system warning light in the instrument
cluster À ashes twice and a beep sound
is heard once.


Type A
Type B

CAUTION
If the system initialization is performed
without adjusting the tyre pressure, the
system cannot detect the normal tyre
pressure and it may not illuminate the
tyre pressure monitoring system warning
light even if a tyre pressure is low, or
it may illuminate the light even if the
pressures are normal.
Adjust the tyre pressure on all four
tyres and initialize the system when
the warning light is turned on. If the
warning light turns on for a reason other
than a À at tyre, the tyre pressure of all
four tyres may have decreased naturally.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.
