Lamps On Reminder
If the manual headlamp control is activated, you will
hear a warning chime if you open either door while
leaving the lamps on. An exception to this is when
you’re using Twilight Sentinel.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make the high
-
beam headlamps
come on at reduced brightness when:
D the ignition is on,
D the headlamp switch is off and
D the transaxle is not in PARK (P).
When DRL are on, only your high
-
beam headlamps (at
reduced brightness) will be on. No other exterior lamps
such as the parking lamps, taillamps, etc. will be on
when the DRL are being used. Your instrument panel
won’t be lit up either.
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 for the DRL.
If it’s dark enough outside and the Twilight Sentinel
control is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended even though the DRL
are still illuminated (it’s become dark enough outside to
require the headlamps and/or other exterior lamps).
Turning on the Twilight Sentinel, the headlamp switch
or the fog lamp switch will remove the HEADLAMPS
SUGGESTED message.
To idle your vehicle with the DRL off, turn off the
Twilight Sentinel switch 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).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
