Cadillac 2009 STS, Owner'S Manual

Page: 121 / 514

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 or off,
press the CONFIG hard key located on the navigation
radio, then press
@
. See “Configure Menu” in the index
of the Navigation System manual. The symbol will be
highlighted when the feature is active.
When the vehicle is started, the LDW symbol that is
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.
LDW is not currently operating and will not warn you if
the LDW symbol does not appear.
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. For cleaning instructions, see
Washing Your Vehicle on page 5-118.
LDW warnings may occasionally occur due to tar marks,
shadows, cracks in the road, or other road imperfections.
This is normal system operation, the vehicle does not
need service.
