Twilight Sentinel Automatic Lamp
Control (Optional, Standard in Canada)
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 isn't covered.
You can customize your vehicle to turn Twilight
Sentinel on or off (except for vehicles first sold in
Canada). See ªDriver Information Center (DIC)º in the
Index to turn this feature on or off.
When Twilight Sentinel is turned on, you will see the
following happen:

When it's 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's bright enough outside, the headlamps will
go off, and the front turn signal lamps (DRL) will
come on, as long as the headlamp switch is in the
OFF position.
With Twilight Sentinel turned on, you can idle the
vehicle with the lamps off, even when it's dark outside.
First set the parking brake while the ignition is in OFF.
Then start the vehicle. The lamps will stay off until you
release the parking brake.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 headlamp switch is moved from OFF to the
parking lamp position, or

a delay time that you select has elapsed.
See ªDriver Information Center (DIC)º in the Index to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition with the headlamp 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.
