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. 518)
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 understanding his/her surround-
ings, 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.
