2-52
Interior Lamps
Brightness Control
Turn the switch next to the headlamp switch up to make
your instrument panel lights brighter. Turn the switch all
the way up to turn on the interior lamps.
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When a door is opened, the dome lamps will come on if
the DOME OVERRIDE button is in the ªoutº position.
When the doors are closed, or the front door handles are
lifted and released, the lamps will stay on for a short
period of time and will turn off automatically. If you use
your keyless entry transmitter to unlock your vehicle,
the interior lights will come on for a short time whether
or not the DOME OVERRIDE button is in the
ªoutº position.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition to help you see
while exiting the vehicle. If the DOME OVERRIDE
button is in the ªoutº position, these lights will stay on
for a short period of time and then will go out.
Front Reading Lamps (If Equipped)
Press the button near each lamp on the overhead console
to turn the reading lamps on and off. The lamps can be
swiveled to point in the desired direction.
If you have the mini console, press the lens on each
lamp to turn it on or off.
Front Map Lamps (If Equipped)
If your vehicle has optional front map lamps, they
are located on the inside rearview mirror. They will
automatically come on for approximately 40 seconds
when the doors are unlocked with the keyless entry
transmitter (if equipped) or until the ignition key is
turned to RUN or ACCESSORY. The lamps will also
stay on for approximately 40 seconds after you exit
the vehicle unless you lock the doors with the keyless
entry transmitter.
You can also turn the lamps on and off by pressing the
switch near each lamp.

2-53 Dome Lamps
The dome lamps will come on when you open a door.
You can also turn the dome lamps on by rotating the
thumbwheel, located next to the parking/headlamps
knob, all the way up to the top detent position. In this
position, the dome lamps will remain on until they are
turned off.
You can use the DOME OVERRIDE button, located
below the parking/headlamp knob, to set the dome
lamps to come on automatically when a door is opened,
or to remain off. To turn the lamps off, press the button
into the ªinº position. With the button in this position,
the dome lamps will remain off when a door is open.
To return the lamps to automatic operation, press the
button again and return it to the ªoutº position.
With the button in this position, the dome lamps will
come on when you open a door. This will override the
illuminated entry feature, unless you use your remote
keyless entry transmitter to unlock the vehicle.
Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box and underhood lamps if they are left
on for more than 20 minutes when the ignition is off.
This will keep your battery from running down.If the battery run
-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:

Shut off all lamps and close all doors, or

turn the ignition key to RUN.
Mirrors
Inside Day/Night Rearview Mirror
Pull the tab under the mirror toward you to reduce glare
from headlamps behind you after dark. Push the tab
away from you for normal daytime operation.

2-54 Electrochromic Day/Night Inside Rearview
Mirror (If Equipped)
This mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the back of the
mirror senses when it is becoming dark outside. Another
photocell built into the mirror surface 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. The mirror will also
return to its clear daytime state when the vehicle is put
into REVERSE (R).Press the AUTO button at the base of the mirror to turn
on the automatic feature. The button has an indicator
light to show it is on. Press the OFF button to turn the
automatic feature off.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.

2-56 Electrochromic Outside Rearview Mirror
(If Equipped)
Only the driver's side outside mirror will adjust for
the glare of headlamps behind you. See ªElectrochromic
Day/Night Inside Rearview Mirrorº earlier in
this section.
Heated Outside Rearview Mirror
(If Equipped)
When you operate the rear window defogger, a defogger
also warms the heated outside rearview mirrors to help
clear them of ice, snow and condensation. See ªRear
Window Defoggerº in the Index for more information.
Storage Compartments
Glove Box
To open your glove box, lift the lever on the front of the
glove box and lower the door. The glove box should not
be open while driving.
Overhead Console (If Equipped)
The overhead console includes reading lamps, a
compartment for a garage door opener, a temperature
and compass display and a storage compartment
for sunglasses.
Some models have a driver information system in the
console. See ªDriver Information Systemº later in
this section.

4-21 Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.

Use a low gear and get a firm grip on the
steering wheel.

Get a smooth start up the hill and try to maintain
your speed. Don't use more power than you need,
because you don't want your wheels to start spinning
or sliding.

Try to drive straight up the hill if at all possible.
If the path twists and turns, you might want to find
another route.
CAUTION:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up hills,
always try to go straight up.

Ease up on your speed as you approach the top
of the hill.

Attach a flag to the vehicle to make you more visible
to approaching traffic on trails or hills.

Sound the horn as you approach the top of the hill to
let opposing traffic know you're there.

Use your headlamps even during the day. They make
you more visible to oncoming traffic.
CAUTION:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop
-off,
embankment, cliff, or even another vehicle. You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.

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.
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.

4-31
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.
Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can't stop, accelerate or turn as well because
your tire
-to-road traction isn't as good as on dry roads.
And, if your tires don't have much tread left, you'll get
even less traction. It's always wise to go slower and be
cautious if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.

4-43
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.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
