Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS)
*
The LAS & LDWS alerts the driver that the vehicle may be deviating from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yellow lines) 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. Use the system when you
drive the vehicle on roads with white (yello w) lines such as expressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-201.

Do not rely completely on the LAS & LDWS:
 The LAS & 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 LAS & LDWS is limited. Always stay on course using the steering
wheel and drive with care.
Do not use the LAS & LDWS in the following cases:
The system may not operate adequately accordin g 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 oth er 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 repeatedly 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.
Heavy luggage is loaded in the luggage compartment or on the rear seat and the
vehicle is tilted.
The tire pressures are not adjusted to the specified pressure.
