Twilight
Sentinel
Twilight Sentinel provides a period of exterior
illumination as you leave the vicinity of your vehicle.
The feature is activated when your vehicle’s headlamps
are on due to the automatic headlamp control feature
described previously
in
this section, and when your
vehicle’s ignition is turned off. Your headlamps will
then remain
on
until the headlamp switch is moved from
OFF
to the parklamp position or until a
90
second
illumination period has elapsed.
If you turn off the ignition with the headlamp switch in
the parklamp or headlamp position, the Twilight
Sentinel cycle will not occur.
You can customize the vehicle
to
activate the Twilight
Sentinel when your vehicle’s ignition is turned off under
the conditions described above, or you may choose not
to activate this feature under any conditions. The
enabled/disabled state of this feature will be toggled
when you perform the following sequence with the
doors closed and the ignition key
in
the RUN position:
Press and hold
the
power door lock switch. While
holding
the
door lock switch, cycle the headlamp switch
on
and then off two times. Release the power door lock
switch. These operations must be carried out
in
a
time
period
of
less than
10
seconds, followed by a delay
period of no more than
10
seconds. Then, press and hold
the power door unlock switch. While holding the door
unlock switch, cycle the headlamp switch on and then
off two times. Release the courtesy door unlock switch.
These operations must be carried out
in
a time period
of
less than
10
seconds.
After releasing the door unlock switch, a single chime
will be heard if the Twilight Sentinel function has been
disabled; two chimes
will
be heard
if
the
feature has
been enabled. This feature will be enabled when your
vehicle is shipped from the factory. Disconnecting the
vehicle’s battery for up to a year will not change the
programmed operation of this feature.
