Functions and Activation Conditions
for Lane Departure Warning (LDW)
The Detroit Assurance LDW system is designed to
warn the driver as the vehicle crosses the outer
boundary of the lane marking. This may differ from
other LDW systems which issue a warning as the
driver approaches the inside of the lane marking. If
the system warns at, or just beyond the outer edge
of the lane marking, the system is performing as de-
signed. If the warning does not occur, or occurs after
an excessive lane departure, the system may not be
operating properly.
In addition to acting as a warning, lane markings on
the driver display screen show the status of Lane
Departure Warning. No lane markings or outlined
lane markings indicate the Lane Departure Warning
is off. Solid white or red lane markings indicate Lane
Departure Warning is active.
LDW only issues warnings if the speed is above ap-
proximately 37 mph (60 km/h).
When driving over lane markings unintentionally, the
volume of audio equipment like the radio and/or
hands-free systems is muted and a direction-related
"rumble-strip noise" sounds from either the left or
right door speaker.
Lane Departure Warning does not issue a warning if:
•
the turn signals are switched on;
•
there is braking or acceleration; or
•
a driving safety system such as Active Brake
Assist (ABA), Stability Control, or Adaptive
Cruise Control (ACC) intervenes.
Activating or Deactivating Lane
Departure Warning (LDW)
When the engine is turned on, Lane Departure Warn-
ing (LDW) is automatically activated.
NOTE: There is no audible self-test of the
"rumble-strip noise" of the LDW when the key is
turned on.
Pressing the physical LDW OFF switch will deacti-
vate Lane Departure Warning for fifteen minutes.
See
Fig. 6.8 . When the LDW is deactivated, the
switch will illuminate.
A driver might want to turn off Lane Departure Warn-
ing on winding roads or when driving through con-
struction zones or other areas where lane markings
are not clear.
NOTE: Vehicles equipped with D.A. 5.0 and an
MPC2 camera, but no LDW system may have a
permanently illuminated LDW OFF switch as
LDW has been disabled.
LDW is not active if:
•
the driver presses the LDW OFF switch; or
•
the system is searching for a lane.
If there is a system error, the LDW telltale will illumi-
nate in the driver display. See
Fig. 6.9 .
Cleaning the Windshield in the Area
of the Camera
Make sure that the windshield is always kept clean
and unobstructed in the area of the camera. The
driver should switch on the windshield wiper to clean
the windshield and remove snow and ice to avoid
incorrect lane detection.
If the area of the windshield is damaged, Lane De-
parture Warning may not work as intended. If this
happens, the windshield must be replaced.
