NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose. If
you try to use the display as a marker for the
front of your vehicle, such as in a parking lot, you
may misjudge distance and hit an obstacle or
another vehicle.
The HUD controls
are located in the
overhead console.1. Start your engine and slide the HUD dimmer switch
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where you
have the HUD dimmer switch set.
2. Adjust the seat to a comfortable driving position.
Keep pressing the top of the image height adjuster to
raise the image as far as possible.
3. Keep pressing the bottom of the image height
adjuster to move the image as low as possible, while
still keeping it in full view.
4. Slide the dimmer switch downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer switch all
the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer switch. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of the
steering column.

2-99 Care of the HUD
Clean the inside of the windshield as necessary to
remove any dirt or film that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
If You Can't See The HUD Image When the
Ignition is On
If the ignition is on and you can't see the HUD image,
check to see if:

The headlamps are on.

Something is covering the HUD unit.

The HUD dimmer control is adjusted properly.

The HUD image is adjusted to the proper height.

A fuse is blown. See ªFuses and Circuit Breakersº in
the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred or out of focus.
Ultrasonic Rear Parking Assist
(URPA) (Option)
Ultrasonic rear parking assist can help you to determine
how close an object is to your rear bumper within a
given area, making parking easier.
The URPA display is located inside the vehicle, above
the rear window. It has three color
-coded lights that can
be seen through the rearview mirror.
How the System Works
Ultrasonic rear parking assist comes on automatically
when the shift lever is moved into REVERSE (R) and
the vehicle speed is less than 3 mph (5 km/h). When the
system comes on, the three lights on the display will
illuminate to let you know that the system is working.
URPA senses how close your vehicle is to an object. The
distance is determined by the four rear sensors located
on the bumper. When shifting into REVERSE (R) and
an object is detected, one of the following will occur:

At 5 ft. (1.5 m) an amber light will come on.

At 40 in. (1.0 m) two amber lights will come on.

At 20 in. (0.5 m) two amber lights and a red light
will come on and a continuous chime will sound.

At 1 ft. (0.3 m) the chime will still be going
continuously and all three lights will flash.

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.

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.

4-17
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.

4-29

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
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.

6-36 Headlamps
Each headlamp is attached by thumb screws.
1. Remove the thumb screws by turning
them counterclockwise.

6-37
2. Pull the headlamp assembly away from the vehicle.
3. Remove the bulb socket
by turning it one
-quarter
turn counterclockwise,
while pressing it firmly.
Then pull it out. You can
use a tool to remove the
bulb socket if you are
unable to do it by hand.
4. Remove the wire connector from the bulb by
lifting the lock tab and pulling it away from the
plastic base.
5. Replace the old bulb with a new bulb. Make sure not
to touch the new bulb element with your fingers, as
the oils on your hands will reduce bulb life.
6. Reverse Steps 1 through 4 to reassemble the
headlamp assembly.

6-38
When reassembling, make sure to align the pin at the
outboard edge of the headlamp assembly to the plastic
retainer at the outboard edge of the vehicle.Headlamp Aiming
The headlamp aiming device is under the hood, directly
behind the headlamps.
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre
-set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on the
ª0º (zero) marks on their scales.

6-39
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment 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 it 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.
To check the aim, the vehicle should be properly
prepared as follows:

The vehicle must have all four tires on a perfectly
level surface.

If necessary, pads may be used on an uneven 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.

There should not be any cargo or loading of the
vehicle, except it should have a full tank of fuel and
one person or 160 lbs. (75 kg) on the driver's seat.

Close all doors.

Tires should be properly inflated.

Rock the vehicle to stabilize the suspension.
Start with the horizontal aim. The adjustment
screws can be turned with an E8 Torx
 socket or
T15 Torx screwdriver.
Once the horizontal aim is adjusted, then adjust the
vertical aim.

6-40
1. Turn the horizontal
aiming screw (A)
until the
indicator (B) is
lined up with zero.
2. Turn the vertical aiming screw (C) until the level
bubble (D) is lined up with zero.Front Turn Signal
1. Once the headlamp assembly has been removed,
reach down from the top of the vehicle and, while
pressing the lock tab on the socket, turn the socket
one
-quarter turn counterclockwise and pull it out.
2. Remove the old bulb by
pulling it straight out of
the socket.
3. Replace the bulb and turn the bulb assembly back
into place.
