lines, this function alerts the driver when the vehicle might d epart from
its lane or course
* and provides assistance by operating the steering
wheel to keep the vehicle in its lane or course
*.

paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigu ed, such
as from driving for a long period of time.
● Failure to perform appropriate driving operations and pay caref ul attention
may lead to an accident, resulting in death or serious injury.
● When not using the LDA system, use the LDA switch to turn the system
off.
■ Situations unsuitable for LDA system
In the following situations, use the LDA switch to turn the sys tem off. Failure
to do so may lead to an accident, resulting in death or serious injury.
● Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
● Vehicle is driven on a snow-covered road.
● White (yellow) lines are difficult to see due to rain, snow, fo g, dust, etc.
