When the DRL are on, only your high-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps won't be on.
When it is dark enough outside, your low
-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and your
high
-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel control all the way toward OFF. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps (If Equipped)
The cornering lamps are designed to turn on when
you signal a turn. This will provide more lighting
when cornering.
Twilight Sentinel
Twilight Sentinel turns your
lamps on and off by sensing
how dark it is outside.
To operate it, leave the lamp switch off.
If you move the control all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you move the control
toward OFF, the headlamps will turn off more quickly
when you move your key from RUN. You can change
this delay time from only a few seconds to three minutes.
The exterior lamps can be completely shut off while the
vehicle is in PARK (P) by sliding the Twilight Sentinel
control all the way toward OFF, and releasing it. To turn the
exterior lamps back on, slide the control all the way toward
OFF again, and release it; or, shift out of PARK (P).

2-51 Electrochromic Day/Night Rearview Mirror
(If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror. Your vehicle's mirror may
also contain OnStar
controls.
This is the on/off button for mirrors equipped with
OnStar controls.
When this feature is turned on, the mirror automatically
changes to reduce glare from headlamps behind you.
A photocell on the mirror senses when it is becoming
dark outside. Another photocell built into the mirror
face senses when headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare is reduced.
Mirror Operation
To turn on the automatic dimming feature, press AUTO
(or the on/off button for mirrors equipped with OnStar
controls). To turn off automatic dimming, press OFF
(or the on/off button for mirrors equipped with OnStar
controls). The indicator light will be illuminated when
this feature is active.
Electrochromic Day/Night Rearview Mirror
with Compass (If Equipped)
Your vehicle may have an electrochromic inside
rearview mirror with a compass. Your vehicle's mirror
may also contain OnStar
controls.
This is the on/off button for mirrors equipped with
OnStar controls.
Pressing the MIRROR button (or the on/off button
for mirrors equipped with OnStar controls) located at
the bottom of the mirror, turns the automatic dimming
feature on or off.
The mirror also includes an eight
-point compass
display in the upper right corner of the mirror face.
When on, the compass automatically calibrates as the
vehicle is driven.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.

Sun Visors
Illuminated Visor Vanity Mirrors
When you open the cover to either the passenger's
or driver's visor vanity mirror, the lamps will turn on.
The brightness of the lamp can be adjusted by sliding
the switch up or down.
Dual Sun Visors
Each sun visor has two parts, so that both the windshield
and door glass can be shaded at the same time. To use
the dual sun visors, flip the first visor down and turn it
toward the window. Then, flip the second visor down
toward the windshield.
Auxiliary Power Outlets
Your vehicle may have one or three power outlets
depending on the type of front seat you have. If your
vehicle has front bucket seats with a center console,
you will find one outlet inside the storage compartment
and the other on the lower front edge of the console.
(An extra power outlet can be found in the ashtray.)
The power outlets can be used to plug in electrical
equipment such as a cellular telephone or CB radio.
Follow the proper installation instructions that are
included with the equipment you install.Certain power accessory plugs may not be compatible
to the auxiliary power outlet and could result in blown
vehicle or adapter fuses. If you experience a problem
see your dealer for additional information on the power
accessory plugs.
The auxiliary power outlets will only operate when the
ignition key is in RUN and for 10 minutes after turning
the ignition off. If you would like the outlets to operate
regardless of ignition position, and for unlimited periods
of time, see ªEngine Compartment Bussed Electrical
Centerº in the Index or see your dealer.
NOTICE:
When using an auxiliary outlet:
The maximum load of any electrical
equipment should not exceed 15 amps.
Be sure to turn off any electrical
equipment when not in use. Leaving
electrical equipment on for extended
periods of time can drain your battery.

Sunroof (Option)
If your vehicle has this
option, the switch for the
sunroof is located between
the sun visors.
The sunroof switch can be operated in four directions to
control sunroof movement. The switch will only work
when the ignition is on or when the retained accessory
power is active.
The sunroof has both manual and express features for
opening the glass panel and sunshade.Press and hold the switch rearward to the first position
to open the glass panel and sunshade. The sunshade can
also be opened by hand. To close the glass panel, press
and hold the switch forward. As the glass panel closes,
it will open slightly towards the vent position to provide
a better seal. The sunshade can only be closed by hand.
Press and release the switch rearward to the second
position to express open the glass panel. It will stop in
a partially open position. The glass panel may be fully
opened by pressing the switch rearward again. When
the glass panel is express opening, pressing the switch
in any direction will stop it. If you press and hold the
switch in the express open position for more than one
and a half seconds, the express open operation will be
overridden and the sunroof will operate manually.
To vent open the glass panel, press and hold the
switch upward. The sunshade must be opened by
hand. To close the glass panel, pull and hold the
switch downward.

2-73 Battery System Warning Light
When you turn the key
to RUN, this light will
turn on briefly to show
that the generator and
battery charging systems
are working.
If the light stays on, a chime will sound indicating that
the vehicle needs service. You should take your vehicle
to the dealer as soon as possible. To save the battery
until you get there, turn off all accessories and set the
climate control system to OFF.
Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on when you turn the key to
RUN. If it doesn't come on then, have it fixed so it
will be ready to warn you if there's a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the

CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn't
release fully. If you try to drive off with the parking
brake set, a chime will also come on until you release
the parking brake. If the light stays on after your
parking brake is fully released, it means you have a
brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when your
engine is started and may
stay on for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you're driving, your vehicle needs
service. If the regular brake system warning light isn't
on, you still have brakes, but you don't have anti
-lock
brakes. If the regular brake system warning light is
also on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section.
The anti
-lock brake system warning light should
come on briefly when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so it will
be ready to warn you if there is a problem.

NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
