CHEVROLET CORVETTE 2005 - Manual (Page 143)

Twilight Sentinel ®
Twilight Sentinel ® can turn your lamps on and off
for you. A light sensor on top of the instrument panel
makes the Twilight Sentinel
® work, so be sure it is
not covered.
With Twilight Sentinel ® , you will see the
following 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 AUTO position.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave 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, your instrument panel
cluster may not be as bright as usual. Make sure
your instrument panel brightness control is in full bright
position. See Instrument Panel Brightness on
page 3-18.
You can idle the vehicle with the lamps off, even when
it is dark outside.
After starting the vehicle, turn the exterior lamp control
band on the multifunction lever to off and then
release it. The lamps will remain off until you turn the
control band to off again.
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, your lamps
will remain on until:
• The exterior lamp switch is moved from off to the
parking lamp position, or
• a delay time that you select has elapsed.
See “Personal Options” under DIC Vehicle
Personalization on page 3-67 to select the delay time
that you want. You can also select no delay time.
If you turn off the ignition 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, you should turn on the regular
headlamp system when you need it.
