Section 2 Features and Controls
2-1

Mirrors
Manual Rearview Mirror
You can adjust the mirror for day or night driving. Press
the tab forward (away from you) for day driving. Pull
the tab back (toward you) for night driving.
Outside Manual Mirror
Adjust your outside rearview mirrors so you can see a
little of the side of your vehicle and the area beside and
behind your vehicle, from a comfortable driving
position.
You can fold the mirrors inward before entering a car
wash. Pull the mirrors toward the vehicle. Push the
mirrors back out when nished. After pushing the mirror
out, the adjustment will be maintained.
Outside Power Mirrors
Your vehicle may have this feature.
To adjust the outside rearview mirror, move the selector
switch in the middle of the control to L for the driver’s
side mirror or to R for the passenger’s side mirror. Then
use the arrows located on the four-way control pad to
move the mirror in the desired direction. To make
sure you do not accidentally move a mirror, return the
selector switch to the middle position (off) after adjusting
the mirrors.

Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot 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 are 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
are driving, do not 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 re-adjust to the dark. When
you are faced with severe glare, as from a driver
who does not 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 lm caused by dust. Dirty glass makes
lights dazzle and ash 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 is 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
are not even aware of it.
