It's dangerous to shift from N or P into a
driving gear when the engine is running
faster than idle. If this is done, the vehicle
could move suddenly, causing an accident
or serious injury.
Do not shift into N when driving the
vehicle:
Shifting into N while driving is dangerous.
Engine braking cannot be applied when
decelerating which could lead to an
accident or serious injury.

¾Do not shade the light sensor by adhering a sticker or a label on the windscreen. Otherwise
the light sensor will not operate correctly.

¾The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windscreen when the wiper lever is in the AUTO position and the
ignition is switched ON as fingers could be pinched or the wipers and wiper blades
damaged when the wipers activate automatically. If you are going to clean the windscreen,
be sure the wipers are turned off completely Š this is particularly important when clearing
ice and snow Š when it is particularly tempting to leave the engine running.
NOTE
xThe headlights, other exterior lights and instrument panel illumination may not turn off
immediately even if the surrounding area becomes well-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffic jams inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the OFF position.
xWhen the headlight switch is in the AUTO position and the ignition is switched to ACC or
the ignition is switched off, the headlights, other exterior lights and instrument panel
illumination will turn off.
xThe instrument panel illumination can be adjusted by rotating the knob in the instrument
cluster. Also, the antidazzle mode can be changed by rotating the knob until a beep sound
is heard. To adjust the brightness of the instrument panel illumination: Refer to
Instrument Panel Illumination on page 4-30.
xThe sensitivity of the AUTO lights may be changed by an Authorised Mazda Repairer.
Refer to Personalisation Features on page 9-15.

¾When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
¾If the windscreen above the rain sensor
is touched or wiped with a cloth.
¾If the windscreen is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windscreen when the wiper lever is in the
AUTO position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windscreen,
be sure the wipers are turned
off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.
NOTE
xSwitching the auto-wiper lever from the
OFF to the AUTO position while driving
activates the windscreen wipers once,
after which they operate according to
the rainfall amount.
xThe auto-wiper control may not operate
when the rain sensor temperature is
about –10 °C (14 °F) or lower, or about
85 °C (185 °F) or higher.
xIf the windscreen is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and auto-wiper control may
not operate properly.
xIf dirt or foreign matter (Such as ice or
matter containing salt water) adheres to
the windscreen above the rain sensor or
if the windscreen is iced, it could cause
the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the
auto-wiper control will stop operation.
In this case, set the wiper lever to the
low speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper
operation.
xIf the auto-wiper lever is left in the
AUTO position, the wipers could
operate automatically from the effect of
strong light sources, electromagnetic
waves, or infrared light because the rain
sensor uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the OFF position other
than when driving the vehicle under
rainy conditions.
xThe auto-wiper control functions can be
turned off.
Refer to Personalisation Features on
page 9-15.

Do not rely completely on the SCBS R system:
¾The SCBS R 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.
¾To assure the correct operation of the SCBS R, heed the following cautions.
¾Do not apply a sticker to an ultrasonic sensor (rear) (including transparent stickers).
Otherwise, the ultrasonic sensor (rear) may not be able to detect vehicles or obstructions
which could result in an accident.
¾Do not disassemble an ultrasonic sensor (rear).
¾If cracks or damage caused by flying gravel or debris is visible around an ultrasonic
sensor (rear), stop using the SCBS R 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 around an ultrasonic sensor, the
system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping the Smart City Brake Support [Reverse] (SCBS R) System Operation on
page 4-176.
¾Consult an expert repairer (we recommend an Authorised Mazda Repairer) for rear
bumper replacement.
Do not modify the suspension:
If the vehicle height or inclination is changed, the SCBS R system may not operate correctly
because it cannot detect obstructions correctly.
Do not apply a strong force to an ultrasonic sensor (rear):
When washing the vehicle, do not spray highly pressurised water against an ultrasonic sensor
(rear), or rub it strongly. In addition, do not hit the rear bumper forcefully when loading and
unloading cargo Otherwise, the sensors may not detect obstructions correctly which could
cause the SCBS R system to not operate normally, or it could operate unnecessarily.
&$87,21
¾When driving off-road in areas where there is grass or foliage, it is recommended that the
SCBS R system be turned off.
¾Always use tyres of the
specified size and the same manufacturer, brand, and tread pattern
on all 4 wheels. In addition, do not use tyres with significantly different wear patterns on the
same vehicle. Otherwise, the SCBS R system may not operate normally.
:KHQ'ULYLQJ
L$&7,96(16(


¾If ice or snow is stuck on the ultrasonic sensors (rear) they may not be able to detect
obstructions correctly depending on the conditions. In such cases, the system may not be
able to perform controls correctly. Always drive carefully and pay attention to the rear of
the vehicle.
NOTE
xThe vehicle posture changes depending on the accelerator pedal, brake pedal and
steering wheel operations, which could make it difficult for the system to recognise an
obstruction, or it could facilitate unnecessary detection. In such cases, the SCBS R may or
may not operate.
xThe SCBS R system will operate under the following conditions.
xThe Smart City Brake Support (SCBS) warning light (amber) does not illuminate.
xThe engine is running.
xThe change lever (manual transaxle vehicle) or the selector lever (automatic transaxle
vehicle) is in the R (reverse) position.
xThe vehicle speed is between about 2 to 8 km/h (2 to 4 mph).
xThe SCBS R is not turned off.
xThe DSC is not malfunctioning.
xThe SCBS R operates using ultrasonic sensors (rear) which detect obstructions at the rear
by emitting ultrasonic waves and then receiving the returning waves reflected off the
obstructions.
xIn the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
SCBS R may not operate.
xThe height of the obstruction is low such as low walls or trucks with low loading
platforms.
xThe height of the obstruction is high such as trucks with high loading platforms.
xThe obstruction is small.
xThe obstruction is thin such as a signpost.
xThe obstruction is positioned away from the centre of the vehicle.
