*Some models.
Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS)*
The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) alerts the
driver that the vehicle may be deviating from its lane and it provides s\
teering assistance to
help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yellow line\
s) of the vehicle
lane in which the vehicle is traveling and if the system determines that\
the vehicle may
deviate from its lane, it operates the electric power steering to assist\
the driver's steering
operation. The system also alerts the driver by activating a lane departure warning\
sound,
vibrating the steering wheel, and indicating an alert in the display.
Refer to Forward Sensing Camera (FSC) on page
4-136.

WARNING
Do not rely completely on the Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS):
 The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) is not an
automatic driving system. In addition, the system is not designed to compensate for a
driver's lack of caution, and over-reliance on the system could lead to an accident.
 The detection ability of the Lane-keep Assist System (LAS) & Lane Departure Warning
System (LDWS) is limited. Always stay on course using the steering wheel and drive
with care.
Do not use the Lane-keep Assist System (LAS) & Lane Departure Warning System
(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 heav y traffic and insufficient distance between vehicles. Roads with no whit e (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.
 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 Lane-keep Assist System (LAS) & Lane Departure
Warning System (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 Lane-keep \
Assist System
(LAS) & Lane Departure Warning System (LDWS) is automatically disabled. The
Lane-keep Assist System (LAS) & Lane Departure Warning System (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 abr\
uptly and the vehicle
moves close to a white (yellow) line, the system determines that the d\
river is making a lane
change and the Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
operation is temporarily canceled. The Lane-keep Assist System (LAS) & Lane Departure
Warning System (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 repeatedly within a short period of time, the Lane-
keep Assist System (LAS) & Lane Departure Warning System (LDWS) may not operate. When white (yellow) lane lines ar e not detected, the Lane-keep Assist System (LAS) &
Lane Departure Warning System (LDWS) does not operate. Under the following conditions, the Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS) may not be able to detect white (yellow) lane l\
ines 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. Heavy luggage is loaded in the luggage compartment or on the r ear seat and the
vehicle is tilted. The tire pressures are not adjusted to the specified pressure. Tires other than conventional tires are equipped. When the vehicle is driven on the guiding branch to or from the rest area or tollgate of
a highway. The white (yellow) lane lines are less visible because of dirt or fading/patchiness. A vehicle in front of your vehicle is running near a white (yellow) lane line making \
it
less visible. A white (yellow) lane line is less visible because of bad weather (rai\
n, fog, or snow). The vehicle is driven on a temporary lane or section with a closed lane \
resulting from
construction where there may be multiple white (yellow) lane lines or they are interrupted.
 A misleading line is picked up on the road such as a temporary line for construction,
or because of shade, lingering snow, or grooves filled with water. The surrounding brightness suddenly changes such as when entering or exiting a t\
unnel. The illumination of the headlights is weakened because of dirt or the op\
tical axis is
deviated. The windshield is dirty or foggy . The windshield, camera is fogged (water dr oplets). Back-light is reflected off the road surface. The road surface is wet and shiny after rain, or there are puddles on the road. The shade of a guar drail parallel to a white (yellow) lane line is cast on the road. The width of the driving lane is narr ow (less than about 2.5 m (98 in)) or wide (more
than about 4.5 m (178 in)) Driving on roads with tight curves. The road is excessively uneven. The vehicle is shaken after hitting a r oad bump. There are two or more adjacent white (yellow) lane lines. There are various road markings or lane markings of various shapes near an intersection.

The Lane-keep Assist System (LAS) & Lane Departure Warning System (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 of f 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.
NOTE
 The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) does not
operate until the system detects white (yellow) lane lines on either t\
he left or right. When the system detects a white (yellow) lane line on one side only , the system will not
activate warnings for the lane line on the side that is not being detect\
ed. The warning is
only for a lane deviation on the side that is being detected.
 If you take your hands off the steering wheel (not holding the steering\
wheel), the warning
sound is activated and an alert is indicated in the active driving displ\
ay.

If the steering wheel is held lightly, or depending on the road conditions, the system may
detect that you have released the steering wheel (not holding the steering wheel) even if
you are holding it, and display a message in the active driving display.
 The timing at which the lane departur e warning is activated and the steering wheel
operation assist is performed varies. The following settings for the Lane-keep Assist System (LAS) & Lane Departure Warning
System (LDWS) can be changed. Refer to Personalization Features on page 9-12.
