not require a lot of repeated acceleration
and deceleration.
WA R N I N G
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
 Roads with sharp curves and where
vehicle
traffic is heavy and there is
insufficient space between vehicles.
(Driving under these conditions using the
cruise control function is not possible)
 Steep down slopes (Set speed may be
exceeded because
sufficient engine
braking cannot be applied)

Lane-keep Assist System (LAS) & Lane DepartureWarning System (LDWS)
*
The LAS&LDWS alerts the driver th at 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 (yello w lines) of the vehicle
lane in which the vehicle is traveling and if the system determ ines 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 la ne departure warning sound,
vibrating the steering wheel, and indicating an alert in the di splay. Use the system when you
drive the vehicle on ro ads with white (yellow) lines such as ex pressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-131.

Camera (FSC)
WA R N I N G
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 limi ted. Always stay on course using the steering
wheel and drive with care.
When Driving

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.
