Exterior Lamps
The control located on
the left side of the
instrument panel operates
these lamp systems:

Parking Lamps

Headlamps

Taillamps

Sidemarker Lamps

License Plate Lamp

Underhood Lamp

Fog Lamps (STS Only)

Instrument Panel Lights
Instrument panel backlighting will dim only when it is
dark enough outside.
Parking Lamps
Turn the exterior lamps knob once clockwise to turn on
the parking lamps, taillamps, sidemarker lamps, license
plate lamp and underhood lamp. Turn the control
counterclockwise to turn these lamps off. The parking
brake indicator light will be on if the parking lamps are
on (with the engine off and the ignition in ACC or ON).
Headlamps
Turn the exterior lamps knob all the way clockwise to
turn the headlamps on. Turn the knob all the way
counterclockwise to turn the headlamps off.
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.

2-47
Wiper-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds. To operate, the Twilight
Sentinel

feature must be turned on. See ªTwilight
Sentinelº in the Index for more information.
When the exterior lamp control is in the off or parking
lamp position and the wiper control is on (INT, LO or
HI), the HEADLAMPS SUGGESTED message will
appear on the Driver Information Center (DIC).
When the ignition is turned to OFF, the wiper
-activated
headlamps will immediately turn off. The wiper
-activated
headlamps will also turn off if the Twilight Sentinel or
the windshield wipers are turned off.
Lamps On Reminder
You will hear a warning chime if you open the driver's
door while leaving the lamps on and the exterior lamps
control is activated. An exception to this is when you're
using Twilight Sentinel or if the ignition is on.
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. Fully
functional daytime running lights are required on all
vehicles first sold in Canada.
The DRL system will make the high
-beam headlamps
come on at reduced brightness when the following
conditions are met:

The ignition is on,

the headlamp switch is off and

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.

2-48
When the Twilight Sentinel
lever 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 lever 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 enough outside and the Twilight Sentinel
lever 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.

2-49
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

This lever is located
below the exterior
lamps control knob.
It automatically turns
the lamps on and off
by sensing how dark
it is outside.
To operate the Twilight Sentinel, leave the exterior
lamps control knob off and slide the TWILIGHT lever
to any position but OFF.If you slide the lever all the way to the right, the lamps
will remain on for approximately three minutes after the
ignition has been turned to OFF or ACC. If you slide the
lever so it is just on, the lamps will go off quickly when
you turn the ignition out of ON. You can adjust the
delay time from only a few seconds to three minutes.
If it's dark enough outside and Twilight Sentinel is
turned 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 (it has become dark
enough outside to require the headlamps and/or other
exterior lamps). Turning on the Twilight Sentinel, the
headlamps or the fog lamps will remove the
HEADLAMPS SUGGESTED message.

2-50
Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel is located on the driver's side
of the front defogger grille. If you cover the sensor, it
will read ªdarkº and the lamps will come on.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately
ten minutes after the ignition is turned to OFF.
This protects against draining the battery in case you
have accidentally left the headlamps or parking lamps
on. The battery saver does not work if the headlamps
are turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamps control knob to
turn the lamps back on. To delay the lamps from
turning off, see ªTwilight Sentinelº in the Index.

2-51
Interior Lamps
Instrument Panel
Intensity/Brightness Control
With the parking lamps on, the instrument panel lighting
automatically dims when it becomes dark outside and
brightens when it becomes light outside. When it's dark,
and if the parking lamps are on, the brightness control
can be manually adjusted by using the instrument panel
brightness control.
The button is located to
the right of the Twilight
Sentinel control. Push the
button in to release it to the
outward position.
Turn the button counterclockwise to dim and clockwise
to brighten the lighting. Push the button in to return it to
the original storage position.
Interior Lamps Control
The interior lamps control,
located in the overhead
console, has three positions:
OFF, AUTO and ON.
With the control at AUTO and the front door opened,
the overhead console light, front hush panel lamps and
rear footwell lamps in the door will automatically come
on. When the rear door is opened, all the front door
lighting and rear overhead lamps will come on.
When the control is in ON, the courtesy lamps are
turned on. When the control is in OFF, the lamps are
turned off. (All automatic interior lighting functions are
terminated.) When the interior lamp control is in OFF,
only the driver's door controls and ignition switch
backlighting functions will operate.

2-52
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the driver's door switches
and to the ignition key when a door is opened or if you
press the Remote Keyless Entry (RKE) transmitter
unlock button. The illuminated entry system works with
the light sensor and it must be dark outside in order for
the courtesy lamps or backlighting to turn on. The
courtesy lamps turn off approximately 25 seconds after
the last door is closed or after the ignition key is turned
to ON or if the RKE transmitter lock button is pressed.
The courtesy lamps turn off approximately 40 seconds
after the doors are unlocked with the RKE transmitter if
no door is opened.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the parking lamps are
on. This feature works with the light sensor and is fully
automatic. When the light sensor reads darkness outside,
the instrument panel lights can be adjusted by following
the steps under ªInstrument Panel Intensity/Brightness
Control.º Backlighting to the instrument panel will also
turn on.
Reading Lamps
The reading lamps are located in the roof. These lamps
and the interior courtesy lamps come on when any door
is opened and it is dark outside. The rear lamps come on
when a rear door is opened. Press the button near the
lamps to turn them on and off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical loads
may occur when several of the following are on:
headlamps, high beams, fog lamps, rear window
defogger, high blower fan, heated seats and engine
cooling fans.

2-53
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to
clear the glass, the heated seats may not get as warm as
they usually do and the fan blower may cut back to a
lower speed. For more battery saving information, see
ªBattery Saver Active Messageº in the Index.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, cigarette lighters or the garage door
opener. When the ignition is turned off, the power to
these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened
or the courtesy lamp switch is turned on.
Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass
Your vehicle has an electrochromic inside rearview
mirror with a compass. Your vehicle's mirror also
contains OnStar

controls and may contain passenger
airbag ON and OFF indicators for the Automatic
Occupant Sensor (AOS) System (If Equipped). For
more information about these features, see ªOnStarº and
ªAutomatic Occupant Sensor Systemºin the Index.
