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.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as on
dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is always wise to
go slower and be cautious if rain starts to fall while
you are driving. The surface may get wet suddenly when
your reexes are tuned for driving on dry pavement.

Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators. The aim
has been preset at the factory and should need no
further adjustment. This is true even though your
horizontal aim indicators may not fall exactly on the “0”
(zero) marks on their scales.
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 ash their high
beams at you (for vertical aim). If you believe yourheadlamps need to be re-aimed, we recommend that
you take your vehicle to your dealer for service.
However, it is possible for you to re-aim your headlamps
as described in the following procedure.
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.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps
are 25 ft (7.6 m) from a light colored wall or
other at surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other at surface.
The vehicle should be placed so it is perpendicular
to the wall or other at surface.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg) on
the driver’s seat.
Tires should be properly inated.

Headlamp aiming is done with the vehicle low-beam
lamps. The high-beam lamps will be correctly aimed if
the low-beam lamps are aimed properly.
The headlamp aiming devices are located under the
hood near the headlamps.
If you believe your headlamps need horizontal (left/right)
adjustment, follow the horizontal aiming procedure. If
you believe your headlamps need only vertical
(up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx
®
socket or T15 Torx®screwdriver.
Headlamp Horizontal Aiming
To adjust the horizontal aim, do the following:
1. Open the hood. SeeHood Release on page 5-11
for more information.
2. Locate the horizontal aiming screw (A).
3. Turn the horizontal aiming screw (A) until the
indicator (B) is lined up with zero.
Once the horizontal aim is adjusted, then adjust the
vertical aim.
5-46

Headlamp Vertical Aiming
Notice:Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim rst will result in an
incorrect headlamp aim.
To adjust the vertical aim, do the following:
1. Follow the steps listed underHeadlamp
Horizontal Aiming on page 5-46rst before
adjusting the vertical aim if horizontal aiming needs
to be performed.
2. Find the aim dot on the lens of the
low-beam lamps.
3. Measure the distance from the ground to the aim
dot on each lamp; if left low beam, subtract
2 inches (5 cm). Record this distance.4. At the wall or other at surface, measure from the
ground upward the recorded distance from Step 3
and draw or tape a horizontal line the width of
the vehicle.
5. Turn on the low-beam headlamps.
Notice:Do not cover a headlamp to improve beam
cut-off when aiming. Covering a headlamp may
cause excessive heat build-up which may cause
damage to the headlamp.
6. Place a piece of cardboard or equivalent in front of
the headlamp not being aimed. This should allow
only the beam of light from the headlamp being
aimed to be seen on the at surface.
5-47

7. Turn the vertical aiming
screw (C) until the
headlamp beam
is aimed to the
horizontal tape line.
The top edge of the cut-off should be positioned at
the bottom edge of the horizontal tape line.
8. Repeat the steps for the opposite headlamp.Bulb Replacement

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Wiper Blade

Replacement blades come in different types and are
removed in different ways.
To replace the wiper blade assembly, do the following:
1. Lift the windshield wiper arm away from
the windshield.2. Push the tab on the wiper blade assembly and pull
the assembly down enough to release it from the
U-hooked end of the wiper arm. Slide the assembly
away from the arm.
3. Remove the blade.
4. To reinstall the wiper blade assembly, slide it over
the wiper arm to engage the U-hooked end on the
wiper blade assembly. Pull up on the assembly
to lock it into place.
For the proper windshield wiper blade replacement
length and type, seeNormal Maintenance Replacement
