WARNING
Before using LDA system
■
● Do not rely solely upon the LDA sys-
tem. 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 pay-
ing 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.
When not using the LDA system, use
●
the LDA switch to turn the system off.
