Cadillac 2009 CTS-V Automobile User Manual


 
When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL turns off and the low-beam
headlamps will turn on. When it is bright enough outside,
the low-beam headlamps will go off, and the DRL will turn
back on. If the vehicle is started in a dark garage, the
automatic headlamp system comes on immediately.
Once the vehicle leaves the garage, it takes about one
minute for the automatic headlamp system to change to
DRL if it is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness lever is in the full bright
position. See Instrument Panel Brightness on page 3-20.
Turning the exterior lamp control to off or to the
low-beam headlamp position will turn off the DRL.
If the parking lamps or the fog lamps were turned
on instead, the DRL will still turn off.
This will work regardless of gear position and whether
or not the parking brake is set.
Light Sensor
The light sensor for the
DRL and AUTO headlamp
feature is located on top of
the instrument panel.
If the sensor is covered, it will prevent it from sensing
light, and the exterior lamps or the Headlamps Suggested
message will appear on the DIC whenever the ignition
is on.
