Adjustable Speed Limiter *
The adjustable speed limiter is a function to prevent the vehicle from being driven at a
vehicle speed faster than a set speed. The vehicle speed is controlled to kept it below the set
speed even if the accelerator pedal is depressed.
The adjustable speed limiter can be set between 30 km/h (20 mph) and 200 km/h (125 mph).
The vehicle speed may exceed the set speed when the vehicle is driven on a down slope,
however, the system notifi es the driver by fl ashing the display and operating a warning
sound.
WARNING
Always turn off the system when changing drivers:
If the driver is changed and the new driver is unaware of the adjustable speed limiter
function, the vehicle may not accelerate when the driver depresses the accelerator
pedal, leading to an accident.
The system consists of the adjustable speed limiter display and the speed limiter switch on
the steering wheel.

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.

CAUTION
  When 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.
  Always use tyres for all wheels that are of the specifi ed size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tyres with signifi cantly
different wear patterns on the same vehicle as the Smart City Brake Support (SCBS)
system may not operate normally.
  The laser sensor (front) includes a function for detecting a soiled windscreen and
informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windscreen. 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.
NOTE
  The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering wheel).

NOTE
  The detection ability of the radar sensors (rear) has limitations. In the following cases,
the detection ability may lower and the system may not operate normally.
 


 The rear bumper near the radar sensors (rear) has become deformed.



 Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper.



 Under bad weather conditions such as rain, snow and fog. 

 Under the following conditions, the radar sensors (rear) cannot detect target objects or
it may be diffi cult to detect them.




 Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.
 


 Vehicle shapes which do not refl ect radar waves well such as empty trailers with a
low vehicle height and sports cars.
 
 Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an Authorised Mazda Dealer.
  For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork,
and replacement near the radar sensors, consult an Authorised Mazda Dealer.
  Turn off the system while pulling a trailer or while an accessory such as a bicycle
carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the
radar will be blocked causing the system to not operate normally.
  The radar sensors are regulated by the relevant radio wave laws of the country in
which the vehicle is driven. If the vehicle is driven abroad, authorization from the
country in which the vehicle is driven may be required.

Tyre Pressure Monitoring System
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 specifi 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 4-166 .
The warning light fl ashes when the system has a malfunction.

When Driving
Tyre Pressure Monitoring System
CAUTION
  Each tyre, including the spare (if provided), should be checked monthly when cold
and infl ated to the infl ation pressure recommended by the vehicle manufacturer on the
vehicle placard or tyre infl ation pressure label. (If your vehicle has tyres of a different
size than the size indicated on the vehicle placard or tyre infl ation pressure label, you
should determine the proper tyre infl ation pressure for those tyres.)
 As an added safety feature, your vehicle has been equipped with a tyre pressure
monitoring system (TPMS) that illuminates a low tyre pressure telltale when one or
more of your tyres is signifi cantly under-infl ated. Accordingly, when the low tyre
pressure telltale illuminates, you should stop and check your tyres as soon as possible,
and infl ate them to the proper pressure. Driving on a signifi cantly under-infl ated tyre
causes the tyre to overheat and can lead to tyre failure. Under-infl ation also reduces
fuel effi ciency and tyre tread life, and may affect the vehicle's handling and stopping
ability.
 Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the
driver's responsibility to maintain correct tyre pressure, even if under-infl ation has not
reached the level to trigger illumination of the TPMS low tyre pressure telltale.
 Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly.
 The TPMS malfunction indicator is combined with the low tyre pressure telltale.
When the system detects a malfunction, the telltale will fl ash for approximately
one minute and then remain continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the malfunction exists. When the
malfunction indicator is illuminated, the system may not be able to detect or signal
low tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tyres or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tyres or wheels on your vehicle to ensure that the
replacement or alternate tyres and wheels allow the TPMS to continue to function
properly.
  To avoid false readings, the system samples for a little while before indicating a
problem. As a result it will not instantaneously register a rapid tyre defl ation or blow
out.

When Driving
Tyre Pressure Monitoring System
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 fi rmly
apply the parking brake.
2. Let the tyres cool, then adjust the tyre
pressure of all four (4) tyres to the
specifi ed pressure indicated on the tyre
pressure label located on the door jamb
of the driver's door (door open).
Refer to Tyres on page 9-9 .
3. Switch the ignition ON.
4. While the vehicle is parked, press
and hold the tyre pressure monitoring
system set switch and verify that
the tyre pressure monitoring system
warning light in the instrument cluster
fl ashes twice and a beep sound is heard
once.
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 fl 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.
