4-5. Using the driving support systems
WARNING
Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
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 fatigued, such as
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.

The system may not operate properly and lead to an accident, resulting in
death or serious injury.

sure is low.
