When the Twilight Sentinel switch is on and it’s dark
enough outside, the high
-beam headlamps (at reduced
intensity) will turn off and normal low
-beam headlamp
operation will occur. When the Twilight Sentinel switch
is on and it’s bright enough outside, the regular lamps
will go off, and the high
-beam headlamps at reduced
brightness will take over.
If it’s dark outside and the Twilight Sentinel control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are still
illuminated. This message indicates that it has become
dark enough outside to require the headlamps and/or
other exterior lamps. Turning on the Twilight Sentinel
or the headlamps will deactivate the DRL and remove
the HEADLAMPS SUGGESTED message. If the
parking lamps or the fog lamps were turned on instead,
the DRL will still deactivate and the HEADLAMPS
SUGGESTED message will continue to be displayed.
To idle your vehicle with the DRL off, turn off the
Twilight Sentinel and shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).
To drive your vehicle with the DRL off, turn off the
Twilight Sentinel and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps (STS Only)
Use the fog lamps for better vision in foggy or misty
conditions. When you push the fog lamp button located
next to the exterior lamps control, a small indicator light
in the fog lamp button and the LIGHTS ON and fog
lamp indicator lights on the instrument panel cluster will
tell you that the fog lamps and the parking lamps are on.
Pushing the fog lamp button again will turn them off.
If you turn on the high
-beam headlamps, the fog lamps
will turn off. They’ll turn back on again when you
change to low-beam headlamps. You can use the fog
lamp button to turn the fog lamps on or off when the
parking lamps or headlamps are on.
When the Twilight Sentinel
is on and the fog lamps are
turned on, the fog lamps, headlamps and parking lamps
will remain on.
