WARNING

Before using the LDA

■
Do not over rely on the LDA. The LDA does not drive the vehicle automatically, nor
does it reduce the amount of care you need to take. As such, the driver must always
assume full responsibility for understanding his/her surroundings, for operating the
steering wheel to correct the driving line, and for driving safely. Also, take occasional
rests from fatigue due to driving over long periods of time, etc.
Inappropriate or negligent driving could lead to an unexpected accident.

Do not drive without holding the steering wheel

■
While the steering control function is operating, when the system judges that the vehi-
cle is being driven without holding the steering wheel, a warning message is displayed.
(P. 262)
Inappropriate steering wheel operations and/or negligent driving could lead to an
unexpected accident. When driving, firmly hold the steering wheel and keep safe driv-
ing in mind.

To avoid operating the LDA by mistake

■
Switch the LDA off using the LDA switch when not in use. (P. 263)
