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. To turn off automatic dimming, press OFF.
The green indicator light will be illuminated when this
feature is active.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.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary.
Manual Remote Control Mirror
The outside rearview mirror should be adjusted so you
can just see the side of your vehicle when you are sitting
in a comfortable driving position.
Adjust the driver's side outside mirror with the control
lever on the driver's door.
To adjust your passenger's side mirror, sit in the driver's
seat and have a passenger adjust the mirror for you.

The HUD controls are located to the left of the
steering column.
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
whether the headlamp switch is on or off, and where you
have set the HUD dimmer control.2. Adjust the seat, if necessary, before setting the
height control.
Slide the IMAGE (image height) control all the way up,
raising the image as far as possible. Then slide the HUD
image height control down so the image is as low as
possible but in full view.
3. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn the HUD
off, slide the HUD dimmer control all the way down.
If the sun comes out, or it becomes cloudy, or if you turn
on your headlamps, you may need to adjust the HUD
brightness using the HUD dimmer control. Polaroid
sunglasses could make the HUD image harder to see.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
Spray household glass cleaner on a soft, clean cloth.
Wipe the HUD lens gently, then dry it. Do not spray
cleaner directly on the lens, because the cleaner fluid
could leak inside the unit if you do.

If you can't see the HUD image when the ignition is on,
check to see if:

The headlamps are on

The HUD unit is covered

The HUD dimmer control is adjusted correctly

The HUD image is adjusted to the proper height

A fuse in the fuse panel may be blown. See ªFuses
and Circuit Breakersº in the Index.
If the HUD image is not clear, it could be too bright.
Move the HUD dimmer control further downward. You
may need to clean the windshield and HUD lens.
Your windshield is part of the HUD system. If you ever
have to have a new windshield, be sure to get one
designed for HUD. If you don't, the HUD image may
look blurred and out of focus.Driver Information Center (Option)
If you have the Driver Information Center (DIC), it
gives you important safety and maintenance facts. When
you turn the ignition on, the entire center lights up for a
few seconds. Then it goes to work.

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.
Night Vision
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.

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

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.
H±44±0008±V
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.

Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your dealer's service department.
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.
If you go through a high pressure car wash, or it is very
humid, your headlamps may ªfog up.º This is normal.
The lenses should clear by themselves in time.
Headlamps
For the proper bulb type, see ªReplacement Bulbsº in
the Index.Driver's Side Replacement
