Section 2 Features and Controls
2-1

Mirrors
Manual Rearview Mirror
To reduce glare from lamps behind you, move the lever
toward you to the night position.
Outside Remote Control Mirror
The outside rearview
mirror should be adjusted
so you can see a little
of the side of your vehicle
when you are sitting in
a comfortable driving
position.
Adjust the driver's outside mirror with the control lever
on the driver's door.To adjust your passenger's outside mirror, sit in the
driver's seat and have a passenger adjust the mirror
for you.
The mirror is a spring-loaded breakaway design.
Outside Power Mirrors
If your vehicle has this
feature, the power mirror
control is located on
the driver's door.
Turn the control clockwise or counterclockwise to
choose the mirror you want to adjust. Then move the
control in the direction you want the mirror to move.
Adjust each mirror so you can see a little of the side of
your vehicle when you are sitting in a comfortable
driving position.
The mirror has a spring-loaded breakaway design.

Entry Lighting
When you open either a front door or a rear door, the
lamps inside your vehicle will go on. In addition, if
your vehicle is equipped with remote keyless entry, the
light will come on when the remote keyless entry
UNLOCK button is pressed.
After you exit the vehicle and all of the doors have been
closed, the lamps will stay on for an additional
20 seconds before fading off. The lamps will also fade
to off when the key is inserted and turned to RUN
or ACCESSORY, or the LOCK button on the remote
keyless entry transmitter is pressed.
Front Reading Lamps
If your vehicle has this feature, these lamps are located
on the rearview mirror. Turn each one on and off by
pressing its button.
Map Lamps
If your vehicle has this feature, these lamps are located
in front of the dome lamp. To turn the lamps on,
press the button. Press the button again to turn
them off.
Battery Run-Down Protection
Your vehicle is equipped with a battery saver feature
designed to protect your vehicle's battery.
When any interior lamp (trunk, reading, dome, etc.) is
left on and the ignition is turned off, the battery rundown
protection system will automatically turn the lamp off
after 20 minutes. This will avoid draining the battery.
This system does not protect against leaving on
the headlamps or parking lamps.
To reactivate the interior lamps, do one of the following:
·The ignition must be turned on, or
·the activated interior lamp must be turned off, then
on, or
·any door must be opened.
The battery rundown protection feature will also be
activated when any door is left open.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired Ð 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. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.

Highway Hypnosis
Is there actually such a condition as ªhighway
hypnosisº? Or is it just plain falling asleep at the wheel?
Call it highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Don't
let it happen to you! If it does, your vehicle can leave
the road in
less than a second,and you could crash and
be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
·Make sure your vehicle is well ventilated, with a
comfortably cool interior.
·Keep your eyes moving. Scan the road ahead and
to the sides. Check your rearview mirrors and your
instruments frequently.
·If you get sleepy, pull off the road into a rest,
service or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in ¯at or rolling terrain.
