2018 MAZDA MODEL 3 HATCHBACK brake

Do not use the LAS&LDWS in the following cases:
The system may not operate adequately according to the actual driving conditions, resulting
in an accident.
Driving on roads with tight curves.
 Driving under bad weather conditions (rain, fog, and snow).
 Slippery roads such as ice or snow-bound roads.
 Roads with heavy
traffic and
insufficient distance between vehicles.
 Roads with no white (yellow) lane lines.
 Narrow roads resulting from road construction or lane closures.
 The vehicle is driven on a temporary lane or section with a closed lane resulting from road
construction where there may be multiple white (yellow) lane lines or they are interrupted.
 Vehicle is driven on roads other than expressways and highways.
 The tire pressures are not adjusted to the specified pressure.
 Tires of a different specified size are used, such as an emergency spare tire.
CAUTION
Heed the following cautions so that the LAS&LDWS can operate normally.
Do not modify the suspensions.
 Always use wheels of the
specified type and size for the front and rear wheels. Consult an
Authorized Mazda Dealer for tire replacement.
NOTE
When the turn signal lever is operated for a lane change, the LAS&LDWS is
automatically disabled. The LAS&LDWS becomes operational again when the turn signal
lever is returned and the system detects white (yellow) lane lines while the vehicle is being
driven normally within its vehicle lane.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white (yellow) line, the system determines that the driver is
making a lane change and the LAS&LDWS operation is temporarily canceled. The
LAS&LDWS becomes operational again when the system detects white (yellow) lane lines
while the vehicle is being driven normally within its vehicle lane.
If the vehicle deviates from its lane repe atedly within a short period of time, the
LAS&LDWS may not operate.
When white (yellow) lane lines are not detected, the LAS&LDWS does not operate.
Under the following conditions, the LAS&LDWS may not be able to detect white (yellow)
lane lines correctly and it may not operate normally.
If an object placed on the dashboard is reflected in the windshield and picked up by the
camera.

▼System Operation
If the LAS&LDWS OFF indicator li
ght in the instrument cluster turns off when the ignition
is switched ON, the system goes on standby.

If the LAS&LDWS OFF indicator li ght in the instrument cluster turns on when the ignition
is switched ON, press the LAS&LDWS OFF switch so that the syste m goes on standby.

system becomes operational when all of the following conditions are met.
The engine is running.
The vehicle speed is about 60 km/h (37 mph) or faster.
The system detects white (yellow) lane lines.
(If the system only detects a wh ite (yellow) line on either the left or right the system only
operates for a departure in the direction being detected.)
The driving lane is neither narrow nor wide.

The LAS&LDWS goes on stand-by status in the following cases:
The system cannot detect white (yellow) lane lines.
The vehicle speed is less than about 60 km/h (37 mph).
The ABS/TCS/DSC is operating.
The DSC is turned off.
(If the DSC is turned off while the system is operational, a warning beep is heard and the
system goes on standby.)
The vehicle is making a sharp curve.
The steering wheel is operated abruptly.
The brake pedal is depressed.
The width of a lane is excessively narrow or wide.

Auto cancel
In the following cases, the LAS&LDWS is automatically canceled and the vehicle lane lines
(stand-by) are indicated in the active driving display. In addi tion, when the LAS&LDWS
becomes operational, the system turns back on automatically and the vehicle lane lines
(operational) are indicated in the active driving display.
The temperature inside the camera is high or low.
The windshield around the camera is foggy.
The windshield around the camera is blocked by an obstruction, causing poor forward
visibility.
Auto cancel of warning/steering assist
When the following operations are performed, the LAS&LDWS opera tion is automatically
canceled. The LAS&LDWS is automat ically re-enabled after the operation.

The brake pedal is depressed.
The accelerator pedal is suddenly depressed.
(To cancel the automatic sensitivity cancel function, deselect “Cancel sensitivity” in the
personalization features setting.)
The turn signal lever is operated.
The vehicle crosses a lane line.
NOTE
After the operation, the LAS&LDWS operation may not operate for a period of 5 seconds
at the most until the lane lines are detected.
Under the following conditions, the LAS& LDWS cancels the warning/steering assist
automatically.
The driver takes his/her hands off the steering wheel.
(The LAS&LDWS is designed to assist the driver's steering operation and it will resume
operation automatically when the driver holds the steering wheel.)
The DSC OFF switch is pressed to cancel the DSC.

Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detec ts a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the bra ke control (Smart City Brake
Support (SCBS) brake) when the system determines that a collisi on is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/ h (2 to 18 mph). It may also
be possible to avoid a collision if the relative speed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is i n the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to assist. (Brake Ass ist (Smart City Brake Support
(SCBS) brake assist))

Do not rely completely on the SCBS system:
 The 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.
