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.

When Driving
i-ACTIVSENSE
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.
