2-56 Delayed Headlamp Illumination
Delayed headlamp illumination provides a period of
exterior lighting as you leave the area. The feature is
activated when the headlamps are on due to the
automatic headlamp control feature described previously
in this section, and when the ignition is turned off. Your
headlamps will then remain on until the exterior lamps
control is moved from OFF to the parking lamp position
or until either a 30 second or 60 second lighting period
has ended.
If you turn off the ignition with the headlamp switch in
the parking lamp or headlamp position, the delayed
headlamp illumination cycle will not occur.
To disable the delayed headlamp illumination feature or
change the time of delay, see ªVehicle Customization
Settingsº in the Index.
Fog Lamps (If Equipped)
The fog lamps button is
located on the instrument
panel next to the exterior
lamps control wheel to the
left of the steering column.
Your ignition must be in ON for the fog lamps
to illuminate.
To turn the fog lamps on, press the FOG button. A light
will glow in the button to let you know that the fog
lamps are on. Press the Fog button again to turn the fog
lamps off.
Your parking lamps must be on or your fog lamps won't
come on.
The fog lamps will go off whenever you change to
high
-beam headlamps. When you return to low beams,
the fog lamps will come on again.

Parade Mode
The instrument panel has an added feature called parade
mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you'll still be able to
see the displays.
Rearview Mirror Reading Lamps
Use the switch next to each lamp to turn them
on and off.
Reading Lamps (If Equipped)
The reading lamps are located on the assist handles in
the headliner. These lamps and the interior courtesy
lamps come on when any door is opened. Press the lens
to turn them on. Press it again to turn them off.
Dome Lamp (If Equipped)
The dome lamp will come on when you open a door.
You can also turn this lamp on by turning the exterior
lamps control clockwise as far as it will go. Vehicles that
have the optional sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor vanity
lamps, trunk lamp or glove box lamps.. If you leave any
of these lamps on, they will automatically turn off after
10 minutes, if the ignition is moved to OFF. The lamps
won't come back on again until you do the following:

Turn the ignition on, or

turn the exterior lamps control off, then on again.
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.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.

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. 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
Recreational vehicle towing means towing your vehicle
behind another vehicle
-- such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as ªdinghy towingº (towing your
vehicle with all four wheels on the ground) and ªdolly
towingº (towing your vehicle with two wheels on the
ground and two wheels up on a device known as
a ªdollyº).With the proper preparation and equipment, many
vehicles can be towed in these ways. See ªDinghy
Towingº and ªDolly Towing,º following.
Here are some important things to consider before
you do recreational vehicle towing:

What's the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer's recommendations.

How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.

Do you have the proper towing equipment? See your
dealer or trailering professional for additional advice
and equipment recommendations.

Is your vehicle ready to be towed? Just as you would
prepare your vehicle for a long trip, you'll want to
make sure your vehicle is prepared to be towed.
See ªBefore Leaving on a Long Tripº in the Index.

Bulb Replacement
For the proper type of replacement bulb, see
ªReplacement Bulbsº in the Index.
For any bulb changing procedure not listed in this
section, contact your dealer.
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.
Headlamps
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.
