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 always assume full
responsibility for driving safely by always paying careful attention to the sur-
rounding conditions and operate the steering wheel to correct the 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 system off.
■Preventing LDA system malfunctions and operations performed by
mistake
●Do not modify the headlights or place stickers, etc., on the surface of the
lights.
●Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
●Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).
●If your windshield needs repairs, contact your Toyota dealer.
