Outline<\/p>\n

\u2022 The Lane Departure Warning System (LDWS) recognizes vehicle lane lines on a road using the forward sensing camera (FSC) installed to the windshield, and if the vehicle departs from its lane unknowingly by the driver, the system alerts the driver of the lane departure using a warning indication and warning sound.<\/div>\n
\n
\n
Warning<\/div>\n<\/dd>\n
\n
\n
\u2022 The lane departure warning system (LDWS) is only a supplementary system for the prevention of a lane departure, however the lane departure warning system (LDWS) functions have limitations. Relying solely on the lane departure warning system (LDWS) and neglecting prudent steering wheel operation could cause an unexpected accident resulting in death or serious injury. Do not rely solely on the lane departure warning system (LDWS). Always make lane corrections using the steering wheel and drive safely.<\/div>\n
\u2022 The lane departure warning system (LDWS) may not operate normally under the following conditions:<\/div>\n
\n
\n
\u2015 Poor vehicle lane line visibility due to adverse weather (rain, snow, fog)<\/div>\n
\u2015 Poor vehicle lane line visibility due to backlight, snow on the road, water puddles, road ruts<\/div>\n
\u2015 Poor vehicle lane line visibility due to cracks and fissures in the vehicle lane<\/div>\n
\u2015 Vehicle lane lines intersect with complexity due to additions or reductions of travel lanes<\/div>\n
\u2015 Vehicle lane marking is not completely erased after road maintenance, and there two or more lane lines next to each other<\/div>\n
\u2015 Vehicle lane lines not recognized due to vehicle ahead<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Caution<\/div>\n<\/dd>\n
\n
\n
\u2022 If the forward sensing camera (FSC) aiming is not completed correctly, the forward sensing camera (FSC) cannot record the camera shooting angle and the lane departure warning system (LDWS) may not operate normally. When performing the following servicing, always perform the forward sensing camera (FSC) aiming. In addition, for the forward sensing camera (FSC) aiming procedure, refer to the [FORWARD SENSING CAMERA (FSC) AIMING] in the Workshop Manual.<\/div>\n

Functions<\/p>\n

\u2022 The body control module (BCM) sets warning-trigger lines based on the vehicle lane lines recognized by the forward sensing camera (FSC), and if the vehicle contacts one of these warning-trigger lines it activates the warning indicator and warning sound. For details on the forward sensing camera (FSC) and warning-trigger lines, refer to [FORWARD SENSING CAMERA (FSC)]. (See FORWARD SENSING CAMERA (FSC) [(US)]<\/a>.)<\/div>\n

\u2022 The warning is triggered when all of the following conditions are met:<\/div>\n
\n
\n
\u2015 LDWS system is on<\/div>\n
\u2015 Vehicle speed signal of approx. 64 km\/h {40 mph} or more<\/span> is received from DSC<\/div>\n

Operation<\/p>\n

\n
\n
\u2022 The period of time in which the warning is triggered differs by the period of time in which the vehicle is contacting the warning-trigger line.<\/div>\n
\n
\n
\u2015 Vehicle contacts warning-trigger line for less than 1 sec<\/span>: Warning triggers for approx. 1 sec<\/span><\/div>\n<\/dd>\n<\/dl>\n
\u2022 The following three types of warnings can be selected using the personalization feature.<\/div>\n

\n
1. The forward sensing camera (FSC) sends the vehicle lane line information (1) to the body control module (BCM).<\/div>\n
2. When the body control module (BCM) receives the vehicle lane line information (1) from the forward sensing camera (FSC), it determines (2) the warning sound and the warning indication.<\/div>\n
3. If the body control module (BCM) determines that the warning sound and the warning indication are needed, it sends (3) the warning indication request signal to the instrument cluster, and outputs (3) the warning sound signal to the Notification and Warning Speaker (Front).<\/div>\n
4. When the instrument cluster receives the warning indication request signal from the body control module (BCM), it displays (4) the warning indication in the multi-information display.<\/p>\n\n\n\n
