Function for cancelling illumination dimmer
If the BSM warning indicator lights turn on when the parking lights are turned on, the
brightness of the BSM warning indicator lights is dimmed.
If the BSM warning indicator lights are diffic ult to see due to glare from surrounding
brightness when traveling on snow-covered roads or under foggy conditions, press the
dimmer cancellation button to cancel the dimmer and increase the brightness of BSM
warning indicator lights when they turn on.
Refer to Dashboard Illumination on page 4-14.
Display indicato r (Vehicles with active driving display)
The detected approaching vehicle and warning are displayed in the active driving display
when the vehicle is moving forward (BSM operational).

Smart Brake Support
(SBS)
*
The SBS system alerts the driver of a
possible collision using a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there is the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is pe rformed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, the brakes are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WA R N I N G
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.

1. Activate the cruise control system by
pressing the ON switch. The cruise
main indication (white) is displayed.
2. Accelerate to the desired speed, which
must be more than 25 km/h (16 mph).
3. Set the cruise control by pressing the SET/
switch at the desired speed. The
cruise control is set at the moment the
SET/
switch is pressed. Release the
accelerator pedal simultaneously. The
cruise set indication (white) is
displayed and the cruise set indicator
light (green) turns on.
NOTE
ï‚·The cruise control speed setting cannot
be performed under the following
conditions:
ï‚·(Automatic transaxle)
The selector lever is in the P or N
position.
ï‚·(Manual transaxle)
The shift lever is in the neutral
position.
ï‚·The parking brake is applied.
ï‚·Release the SET/ or RES/ switch at
the desired speed, otherwise the speed
will continue increasing while the RES/
switch is pressed and held, and
continue decreasing while the SET/
switch is pressed and held (except when
the accelerator pedal is depressed).
ï‚·On a steep grade, the vehicle may
momentarily slow down while
ascending, or speed up while
descending.
ï‚·The cruise control will cancel if the
vehicle speed decreases below 21 km/h
(13 mph) when climbing a steep grade.
ï‚·The cruise control may cancel at about
15 km/h (9 mph) below the preset speed
such as when climbing a long, steep
grade.
â–¼ To Increase Cruising Speed
Follow either of these procedures.
To increase speed using cruise control
switch
Press the RES/ switch and hold it. Your
vehicle will accelerate. Release the switch
at the desired speed.

speed indicated in mph: 1 mph (1.6 km/h)
To increase speed using accelerator
pedal
Depress the accelerator pedal to accelerate
to the desired speed. Press the SET/
switch and release it immediately.
NOTE
Accelerate if you want to speed up
temporarily when the cruise control is on.

â–¼To Decrease Cruising Speed
Press the SET/ switch and hold it. The
vehicle will gradually slow.
Release the switch at the desired speed.

Press the SET/
switch and release it

speed indicated in mph: 1 mph (1.6 km/h)
â–¼ To Resume Cruising Speed at More
Than 25 km/h (16 mph)
If the cruise control system temporarily
canceled (such as applying the brake
pedal) and the system is still activated, the
most recent set speed will automatically
resume when the RES/
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 RES/
switch.
â–¼ To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
ï‚·Slightly depress the brake pedal.
ï‚·(Manual transaxle)
Depress the clutch pedal.
ï‚·Press the OFF/CAN switch.
If the RES/
switch is pressed when the
vehicle speed is 25 km/h (16 mph) or
higher, the system reverts to the previously
set speed.
NOTE
ï‚·If any of the following conditions occur,
the cruise control system is temporarily
canceled.
ï‚·The parking brake is applied.
ï‚·(Automatic transaxle)
The selector lever is in the P or N
position.
ï‚·(Manual transaxle)
The shift lever is in the neutral
position.
ï‚·When the cruise control system is
temporarily canceled by even one of the
applicable cancel conditions, the speed
cannot be re-set.
ï‚·(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.
â–¼ To Deactivate
When a cruising speed has been set
(cruise set indication (white) is
displayed/cruise set indicator light
(green) turns on)
Long-press the OFF/CA
N switch or press
the OFF/CAN switch 2 times.
When a cruising speed has not been set

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-29.
Refer to Taking Action on page 7-33.
Refer to Tire Inflation Pressure Warning Beep on page 7-44.

The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in flation pressure label, you should determine
the proper tire inflation pressure for those tires.)
