Pedestrians
Stationary objects (stopped vehicles, obstructions)
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel
even if the selector lever is operated and any intended engine braking will not occur. If
deceleration is required, lower the vehicle speed setting or depress the brake pedal.
The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating.

Cruise Control Function
While this function is operating, the
headway control operation is canceled and
only the cruise control function operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
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 traffi c is heavy and there is
insuffi cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
Steep down slopes (Set speed may
be exceeded because suffi cient
engine braking cannot be applied)
Slippery roads such as ice or snow-
bound roads (Tires could spin
causing you to lose vehicle control)
Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is canceled and the

*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 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.
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 heavy traffi c and insuffi cient 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.
The tire pressures are not adjusted to the specifi ed pressure.
Tires of a diff erent specifi ed 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 specifi ed 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 abruptly and the
vehicle moves close to a white (yellow) line, the system determines that the driver 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.
