Instrument panel brightness control.
Turn the lamp control dial clockwise (to the first
position) to turn on the parking lamps, front and rear
sidemarker lamps, taillamps, license plate lamps, ashtray
lamps, instrument panel lights and backlighting to the
center console controls. Turn the lamp control dial all
the way clockwise (to the second position) to turn on
the low
-beam headlamps.
Turn the lamp control dial counterclockwise to turn
the lamps off.
Headlamps
Turn the lamp control dial all the way to the right to turn
on the low
-beam headlamps.
To turn on the high
-beam headlamps, the low-beam
headlamps must already be on. Push the turn signal lever on
the left side of the steering wheel away from you to engage
the high
-beam headlamps. Pull the lever toward you to
return to the low
-beam headlamps. For more information,
see ªHeadlamp High/Low Beamº in the Index.
Turn the lamp control dial all the way to the left to turn
the headlamps off.
Please note that if the headlamps are activated while
driving and then you turn your vehicle's ignition off
while the lamp dial is still turned on, the headlamps will
turn off. If, however, you open the driver's door while
the lamp dial is still turned on, a warning chime will
sound reminding you to turn the lamp control dial to
OFF. This will stop the warning chime from sounding.
(If you want the headlamps to remain on, you must
manually turn the lamp control dial off and then back
on to the headlamp position. The headlamps will stay
on until manually turned off again.)

2-43
Your vehicle may be equipped with High Intensity
Discharge (HID) headlamps. Your headlamps come on at
a lower intensity and gradually increase to full brightness.
Wiper
-Activated Headlamps
This feature activates the low
-beam headlamps,
parking lamps, sidemarker lamps and taillamps after
the windshield wipers have been in use for about
20 seconds.
The wiper
-activated headlamps light the way in poor
weather and also make your vehicle more visible to
other drivers. If the wipers are on and the ignition switch
is turned off, the headlamps will immediately turn off.
The headlamps will also deactivate if the windshield
wipers have been turned off for about 20 seconds.
Perimeter Lighting
This feature turns on the low-beam headlamps,
parking lamps, sidemarker lamps and taillamps for
about 20 seconds after the unlock button on the
remote keyless entry transmitter is pressed. Perimeter
lighting immediately ends when your vehicle's ignition
is turned to ON or START.
Lamps On Reminder
You will hear a warning chime if you open the door
while leaving the lamps on, if the manual headlamp
control is activated. An exception to this is when
you're using the 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:

your vehicle's ignition is in ON or START,

the low
-beam headlamps are off (the manual lamp
switch is in the off or park lamp position) and

your vehicle's transmission is shifted out of
PARK (P).
When DRL are on, only the 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. The instrument panel
won't be lit up either.

2-44
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 cluster 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.

2-45 Fog Lamps
Use the fog lamps for better
vision in foggy or misty
conditions. Press this button
to turn the fog lamps on
and press the button again
to turn the lamps off.
(The fog lamps only work
when the parking lamps or
the low
-beam headlamps
are on and the ignition
is on.)
This light on the
instrument panel will
come on when the fog
lamp button is pressed.
If you turn on the high
-beam headlamps, the fog
lamps will turn off. They'll turn back on again when
you switch to low
-beam headlamps.
Cornering Lamps
The cornering lamps come on when the headlamps
or parking lamps are on and you signal a turn.
They provide more light for cornering.
Twilight Sentinel

The control for this feature
is located below the lamp
control dial on the left side
of the instrument panel.
It automatically switches
the parking lamps and
low
-beam headlamps on
and off by sensing how
dark it is outside.
To operate the Twilight Sentinel, the ignition must be
in ON or START and the Twilight Sentinel must be
turned on by pressing the OFF button (an indicator
light in the button will be off when the Twilight Sentinel
is activated). If the system senses it is dark enough
outside, the lamps will turn on. The lamps turn off
when the system detects that it is bright outside.

2-46
If you turn the control dial all the way up, the lamps will
remain on for about three minutes after the ignition has
been turned to OFF or LOCK. If you turn the control
dial all the way down, the lamps will go off quickly.
You can adjust the delay time from a few seconds
up to three minutes.
To turn the Twilight Sentinel off, press the OFF button
again. The indicator light in the button will be on. This
lets the driver know that the system has been turned off.
The Twilight Sentinel also turns off if the ignition is
turned to OFF or to LOCK.
This light in the instrument
panel cluster will come on
if the ignition is on and:

the headlamps have not been manually turned on,

the Twilight Sentinel senses it is dark enough outside,

the Twilight Sentinel is OFF and

the transmission is not in PARK (P).Light Sensor
The light sensor for the
Twilight Sentinel is located
in the center of the front
defogger grille.
If you cover the sensor, it will read ªdarkº and the
parking lamps and low
-beam headlamps will come on.

4-17
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50
-year-old
driver may require at least twice as much light to see the
same thing at night as a 20
-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you're
driving, don't wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to readjust to the dark.
When you are faced with severe glare (as from a driver
who doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren't even aware of it.

6-31 High Intensity Discharge (HID) Lighting
(If Equipped)
CAUTION:
The low beam High Intensity Discharge lighting
system operates at a very high voltage. If you
try to service any of the system components,
you could be seriously injured. Have your dealer
or a qualified technician service them.
Halogen Bulbs
CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
Headlamps
1. With a screwdriver, unscrew the fastener on the
headlamp cover and then remove the cover to gain
access to the headlamps. Note that the inner bulb is
for the high
-beam headlamp and the outer bulb is for
the low
-beam headlamp.
