2-48 Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior courtesy lamps, reading/map lamps, visor vanity
lamps, trunk lamp or glove box lamps on. If you leave
any of these lamps on, they will automatically turn off
after 10 minutes, if the ignition is in OFF. The lamps
won't come back on again until you:

turn the ignition on,

turn the lamp switch off, then on, or

open a door.
Note that if your vehicle has less than 15 miles (25 km)
on the odometer, the battery saver will turn off the lamps
after only three minutes.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
flash three times. They will remain on for one more
minute before being turned off automatically.
Retained Accessory Power
With retained accessory power, your power windows,
audio system and sunroof will continue to work up to
10 minutes after the ignition key is turned to OFF and
none of the doors are opened.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.
Inside Day/Night Rearview Mirror
To reduce glare from lamps behind you, pull the lever
at the bottom of the mirror toward you (to the night
position). To return the mirror back to the day position,
push the lever away from you.

2-49 Electrochromic Automatic Dimming
Rearview Mirror (If Equipped)
Your vehicle may have an electrochromic day/night
rearview mirror. Push the button in the center of the
mirror to turn this feature on. The mirror will darken
gradually to reduce glare from headlamps behind you.
This may take a few moments.
The mirror's two outer buttons operate the lights on the
bottom sides of the mirror.
One photocell on the front of the mirror senses when it
is becoming dark outside. Another photocell, facing
rearward, senses headlamps behind you. To turn the electrochromic feature off, press the button
in the center of the mirror again.
To keep the photocells operating well, occasionally
clean them with a cotton swab and glass cleaner.
Power Outside Mirrors
The power mirror control
switch is located near the
driver's side window, on
the armrest.
To choose either the left or right outside mirror, press the
top switch. Press any of the four buttons located below the
top switch to move the mirrors in the desired direction.
Adjust each mirror so you can see the side of your
vehicle and the area behind your vehicle.

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.

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.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.
Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire
-Loading Information label
is on the inside of the trunk lid. The label tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also gives you
important information about the number of people that
can be in your vehicle and the total weight you can
carry. This weight is called the vehicle capacity weight
and includes the weight of all occupants, cargo and all
nonfactory
-installed options.

Headlamp Aiming
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, we recommend that you
take your vehicle to the dealer for service. However, it is
possible for you to re
-aim your headlamps by following
the procedure in the service manual for your vehicle.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
