WARNING
■Before using the LDA system
Do not rely solely upon the LDA system. LDA is not a system which auto-
matically drives the vehicle or reduces the amount of attention that must be
paid to the area in front of the vehicle. The driver must alway s assume full
responsibility for driving safely by always paying careful atte ntion to the sur-
rounding conditions and operate the steering wheel to correct t he path of
the vehicle. Also, make sure to 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 the LDA by mistake
When not using the LDA system, use the LDA switch to turn the s ystem off.
■ Preventing LDA system malfunctio ns and operations performed by
mistake
