(FAB) 0294.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
unintentional lane departures at
speeds of 56 km/h (35 mph) or
greater. LDW uses a camera sensor
to detect the lane markings. The
LDW light,
@, is green if a lane
marking is detected. If the vehicle
departs the lane, the light will
change to amber and flash. In
addition, beeps will sound or the
driver seat will pulse.
See Lane Departure Warning (LDW)
(2500/3500 Series) 0295.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the vehicle approaches a detected lane
marking without using a turn signal
in that direction. It may also provide
a Lane Departure Warning (LDW)
alert as the lane marking is crossed.
The system will not assist or alert if
it detects that you are actively
steering. Override LKA by turning
the steering wheel. LKA uses a
camera to detect lane markings
between 60 km/h (37 mph) and
180 km/h (112 mph).
