WARNING
Before using LDA system
■
Do not rely solely upon the LDA system. The LDA system does not automatically 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 pay-
ing careful attention to the surrounding 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.
