This procedure only changes the mode for the
transmitter used to change this setting. The procedure
will need to be repeated for the second transmitter.
If your vehicle is equipped with the Driver Information
Center (DIC), you must program this feature through
the DIC. See ªDriver Information Centerº in the Index.
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 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,
rear window defogger, high blower fan, heated seats
(if equipped) and engine cooling fans.
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the blower fan,
rear defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Exterior Lighting Battery Saver
If the manual lamp control has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to LOCK and any door has been
opened. This protects draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to leave the lamps on for more than
10 minutes, use the manual control to turn the lamps
back on after the ignition is turned to LOCK and any
door is opened. To delay the lamps from turning off,
see ªTwilight Sentinel

º in the index.

2-50 Front Reading Lamps
Front seat reading lamps are turned on or off by pressing
one of the lamp's buttons.
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 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. To restore power back to
the cigarette lighters the ignition must be turned back
to RUN.
Mirrors
Day/Night Manual Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. The day
-night adjustment allows you to adjust
the mirror to avoid glare from the headlamps behind you.

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.

2-55
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Automatic Dimming/Heated Outside
Rearview Mirror (If Equipped)
If you have this feature, the outside driver's mirror will
adjust for the glare of headlamps behind you. This
feature is controlled using the on and off settings on
the automatic electrochromic day/night rearview mirror.
See ªElectrochromic Day/Night Rearview Mirrorº
earlier in this section.
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's outside
rearview mirrors to help clear them of ice and snow.
Storage Compartments
Glove Box
Use the door key to lock and unlock the glove box.
To open, lift the latch release on the left side of the
glove box door.
Front Storage Armrest
You may have a fold-down armrest between the front
seats that opens into a storage area. Press the buttons
on either side of the armrest to open the storage area for
cassette tapes, gloves, etc.
Front Center Console (Option)
Your vehicle may have a center console that opens to
two storage compartments. The front of the console has
two cupholders that can be unfolded for use. Flip the
center of the console forward to use the built
-in writing
surface on top of the lid.
You will also find an auxiliary power outlet located
inside the storage compartment and one on the lower
front edge of the console. These outlets can be used for
accessories requiring electrical power, such as a cellular
phone or fax machine. See ªAuxiliary Power Outletsº
in the Index.
The console also contains a coinholder as well as
storage for cassette tapes and compact discs.

The information may be displayed in English or metric
units and appears as a reflection in the windshield.
The HUD consists of the following information:

Speedometer Reading

Turn Signal Indicators

High
-Beam Headlamp Indicator

Check Gages Message
The HUD shows these images when they are lighted on
the instrument panel cluster.
Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel, you may not see something important, such as
a warning light.
NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose.
If you try to use the display as a marker for the
front of your vehicle, such as in a parking lot,
you may misjudge distance and hit an obstacle
or another vehicle.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

Since you can't see as well, you may need to
slow down and keep more space between you and
other vehicles.

Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.

In remote areas, watch for animals.

If you're tired, pull off the road in a safe place
and rest.

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.

4-29

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators.
The aim has been pre
-set at the factory and should
need no further adjustment. This is true even though
your horizontal aim indicators may not fall exactly on
the ª0º (zero) marks on their scales.
