Cadillac DTS Owner Manual - 2011
How the System Works
LDW uses a camera located between the inside
rearview mirror and the windshield to detect the lane
markings.
@ (Lane Departure Warning): To turn LDW on and
off, press the LDW control, located by the exterior
headlamp control. An indicator on the control will light to
indicate that LDW is on.
When the vehicle is started, the LDW symbol, located
in the instrument panel cluster, will briefly come on to
indicate that the light is operational.
LDW only operates at speeds of 35 mph (56 km)
or greater. If LDW is turned on when traveling at
these speeds, the LDW symbol will appear green
if the system detects a left or right lane marking.
This symbol will change to amber and flash and
three beeps will sound if you cross a detected lane
marking without using the turn signal.
If the LDW symbol does not appear, LDW is not
currently operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume under DIC Vehicle Customization
on page 4‑77
for more information.
When the System Does Not Seem To Work
Properly
The LDW symbol will not appear when the system is
having difficulty seeing the lines on the road or if the
view of the camera on the windshield is blocked with
mud, dirt, snow, ice, or slush, if the windshield is
damaged, or when weather limits visibility, such as
while driving in fog, rain, or snow conditions. This is
normal operation, the vehicle does not need service.
