Cadillac 2009 Automobile User Manual


 
With Twilight Sentinel the following will happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch
is in the off position.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it will take about one minute
for the automatic headlamp system to change to DRL
if it is light outside. During that delay, the instrument
panel cluster might not be as bright as usual. Make sure
the instrument panel brightness control is in full bright
position. See Instrument Panel Brightness on page 3-40
for more information.
You can idle the vehicle with the lamps off, even when
it is dark outside. First set the parking brake while the
ignition is in OFF/ACCESSORY. Then start the vehicle.
The lamps will stay off until the parking brake is released.
Twilight Sentinel also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel has turned on
the lamps when you turn off the ignition, the lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position.
A delay time that you select has elapsed.
See Vehicle Personalization on page 2-61 to select the
delay time needed. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel delay will not occur. The lamps will turn off
as soon as the switch is turned off.
As with any vehicle, the regular headlamp system
should be turned on when needed.
