When the Twilight Sentinel is on and it's dark enough
outside, the high
-beam headlamps (at reduced intensity)
will change to low
-beam headlamps. When it's bright
enough outside, the regular lamps will go off, and the
high
-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the headlamps off, turn off the
Twilight Sentinel switch and shift the transmission into
PARK (P). Placing your vehicle in PARK (P) disables
the DRL. The DRL will stay off until you shift out of
PARK (P).
If you're not in PARK (P)
and the Twilight Sentinel
system is turned off (and it's
dark enough outside), the
DRL will remain active and
this light on the instrument
panel will appear.
This is a reminder that headlamps are required.The following conditions will override the DRL:

your vehicle's transmission is shifted back into
PARK (P) with the ignition in ON or START,

the low
-beam headlamps are turned on (using the
manual lamp control dial),

the wiper
-activated headlamps are in use (DRL will
come back on 20 seconds after wipers have
turned off),

using the flash
-to-pass feature and

turning on the Twilight Sentinel.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

is pressed.
If you turn on the high

on by pressing the OFF button (an indicator light in the

activated). If the system senses it is dark outside, the
lamps will turn on. The lamps turn off when the system
detects that it is bright outside.

seconds up to three minutes.

the ashtrays. Hot cigarettes or other smoking
materials could ignite them, causing a
damaging fire.

your vehicle's ignition has been turned off.
NOTICE:

while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
