Warning messages for LKA
Warning messages are used to indicate a system malfunction or to inform the
driver of the need for caution while driving. (P. 832)
CAUTION

Before using the LKA system
Do not rely solely on the LKA system. The LKA system 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 under-
standing his/her surroundings, for operating the steering wheel to correct
the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.

To avoid operating the LKA by mistake
Switch the LKA off using the LKA switch when not in use.
