applied immediately.

a.Using the camera located in the windscreen,
the L
ane Assist syst
em det
ects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with a
corrective steering movement. The purpose is
not only to warn the driver, but also to keep
the vehicle inside the lane. This movement
can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required. Control lamp "
