Parade Dimming
This feature prohibits dimming of the digital displays
and backlighting during daylight hours when the key is
in the ignition and the headlamps are on. This feature
operates with the light sensor for the Twilight Sentinel
and is fully automatic. When the light sensor reads
darkness outside and the parking lamps are active, the
digital displays can be adjusted by turning the
instrument panel brightness knob counterclockwise to
dim and clockwise to brighten lighting.
Reading Lamps
The reading lamps are located on the overhead console
on the headliner and in the rear door opening. These
lamps come on automatically when any door is opened
and it is dark outside.
For manual operation, press the button to turn them on.
Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.

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 revolutions per minute (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, fog lamps, rear window
defogger, the climate control fan at high speeds,
heated seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to
clear the glass, the heated seats may not get as warm as
they usually do and the fan may cut back to a lower
speed. For more battery saving information, see ªBattery
Saver Active Messageº in the Index.
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 the garage
door opener. When the ignition is turned off, the
power to these features will automatically turn off after
10 minutes (three minutes if a new car has 15 miles
(24 km) or less). 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.

The mirrors can be manually folded inward to prevent
damage when going through an automatic car wash. To
fold, push the mirror toward the vehicle. To return the
mirror to its original position, push outward. Be sure to
return both mirrors to their original unfolded position
before driving.
The mirrors can also be programmed for personalization
and parallel parking feature if you have the optional
memory package. For more information, see ªMemory
Seat, Mirrors and Steering Wheelº and ªVehicle
Programming and Personalization Featuresº in
the Index.
Driver's Outside Auto-Dimming
Rearview Mirror
The driver's side outside mirror will adjust for the glare
of headlamps behind you. This feature is controlled by
the on and off settings on the electrochromic mirror.
See ªElectrochromic Day/Night Rearview Mirror with
Compassº in the Index.
Curb View Assist Mirror (If Equipped)
If your vehicle is equipped with memory mirrors, it
will also be capable of performing the curb view assist
mirror feature. This feature will cause the passenger's
mirror to tilt to a preselected position when the vehicle
is in REVERSE (R). This feature may be useful
in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
five
-second delay has occurred, the passenger's mirror
will return to its original position.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used.
This feature can be enabled/disabled through the
Driver Information Center. See ªVehicle Programming
and Personalization Featuresº in the Index for
more information.

Night Vision System (Option)
The Night Vision System can help you see better when
you drive at night. The system works by sensing heat
given off by objects in its field of view. Warmer objects,
such as pedestrians, animals and other moving vehicles,
will appear whiter. Colder objects, such as the sky, signs
and parked vehicles, will appear darker.
Use this system as an aid to help you in seeing objects
beyond the headlamps. Do this by occasionally glancing
at the image as you would a rearview mirror. Do not
stare at the image.
The Night Vision System can be operated if:

The instrument panel brightness knob is in any
position except OFF

it is dark enough outside,

the headlamps or fog lamps (if equipped) are on and

the ignition is turned to ON.

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.

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.
