Failure to drive safely and use the system prop-
erly could result in personal injury and/or death
and severe property damage.
Lane Departure Warning (LDW)
Safety Notes
The system may be impaired or may not operate in
the following situations:
•
when there is low visibility due to insufficient
road illumination, or due to snow, rain, fog or
heavy spray
•
when there is glare due to oncoming traffic,
direct sunlight, or reflections from wet road sur-
faces
•
when the windshield in the area of the camera
is dirty, misted up, damaged or covered by a
sticker
•
when no lane markings or several varied lane
markings are present, such as in a construc-
tion zone
•
when the lane markings are worn, dark, or cov-
ered, such as by sand, dirt, or snow
•
when the distance from the vehicle in front is
too small and this prevents the lane markings
from being detected
•
when the lane markings change rapidly, when
lanes branch off, or when they cross or merge
•
when lanes are very narrow or winding
•
when shade conditions on the road surface
change greatly
The driver must adapt their driving style to current
conditions. Lane departure warning cannot take the
road and weather conditions into account, nor the
prevailing traffic situation. The driver is responsible
for the distance to the vehicle in front, for vehicle
speed, braking in good time and remaining in the
lane.
Lane Departure Warning (LDW)
Functions and Activation Conditions
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 de-
parture warning. No lane markings or outlined lane
markings indicate that LDW is off. Solid white or red
lane markings indicate LDW is active.
Lane departure warning only issues warnings if the
speed is above approximately 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.
NOTE: While the LDW audio alert is expected
to sound through the radio speakers on any unit
with a properly installed system, the LDW alert
will only mute the radio output if the radio is
both capable of supporting a mute feature and
is properly configured.
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)
NOTE: There is no audible self-test of the
"rumble-strip noise" of the LDW when the key is
turned on.
When the engine is turned on, LDW is automatically
activated.
Pressing the LDW OFF switch will deactivate lane
departure warning temporarily. See
Fig. 5.9.
Lane departure warning 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. 5.10.
