Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is complete.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it's released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs if the
arrow fails to work when signaling a turn.
Headlamp High/Low Beam
Push forward for high beam to change the headlamps
from low beam to high. Pull the lever back and then
release it to change from high beam to low.
This light located on the
instrument panel will be on,
indicating high
-beam usage.
Flash-To-Pass
This lets you use the high beam headlamps to signal the
driver in front of you that you want to pass.
Pull and hold the turn signal lever toward you to use.
When you do:

If the headlamps are either off or in the DRL mode,
the high beam headlamps will turn on. They'll stay
on as long as you hold the lever there. Release the
lever to turn them off.

If the headlamps are on highbeam, they will switch
to low beam. To return to high beam, push the lever
away from you.

2-48
The DRL system will make the high-beam headlamps
come on at reduced intensity when:

it is still daylight and the ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
When DRL are on, only your high
-beam headlamps
(at reduced intensity) will be on. No other exterior
lamps such as the parking lamps, taillamps, etc. will be
on when the DRL are being used. Your instrument panel
won't be lit up either.
When the Twilight Sentinel control is on and it's dark
enough outside, the high
-beam headlamps (at reduced
intensity) will turn off and automatic high
-beam
headlamp operation will occur. When the Twilight
Sentinel switch is on and it's bright enough outside, the
automatic lamps will go off, and the high
-beam
headlamps at reduced intensity will take over.If it's dark enough outside and the Twilight Sentinel
control is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended even though the DRL
are still illuminated (it's become dark enough outside to
require the headlamps and/or other exterior lamps).
Turning on the Twilight Sentinel, the headlamp switch
or the fog lamp switch will remove the HEADLAMPS
SUGGESTED message.
To idle your vehicle at night with the DRL off, turn
off the Twilight Sentinel and shift the transaxle into
PARK (P). Placing your vehicle in PARK (P) disables
the DRL. The DRL will stay off until you shift out
of PARK (P).
To drive your vehicle at night with the DRL off, turn
off the Twilight Sentinel and manually turn on the
parking lamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-49
Fog Lamps (If Equipped)
Use the fog lamps for better
vision in foggy or misty
conditions. When you press
the fog lamp button, a fog
lamp symbol located in the
instrument panel will come
on to indicate that the fog
lamps and the parking
lamps are on.
Press the button again to turn them off.
If you turn on the high
-beam headlamps, the fog lamps
will turn off. They'll turn back on again when you
switch to low
-beam headlamps.
When the Twilight Sentinel is on and the fog lamp
switch is activated, the fog lamps will remain on as well
as the headlamps and parking lamps.
Cornering Lamps
The cornering lamps come on when the headlamps
or parking lamps are on and you signal a turn with
the multifunction lever. They provide more light
for cornering.
Twilight Sentinel

This control is next to
the headlamp knob. It
automatically switches the
lamps on and off by sensing
how dark it is outside.
To operate the Twilight Sentinel, leave the lamp knob
off and move the TWILIGHT control to any position
but OFF.

Battery Load Management
The battery load management feature is designed to
monitor the vehicle 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 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, high blower fan, heated
seats and engine cooling fans.
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.
Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass (If Equipped)
Your vehicle may have an electrochromic inside
rearview mirror with a compass.
By pressing the MIRROR side of the button located at
the bottom of the mirror, the mirror automatically
darkens to reduce the glare from headlamps behind you.
The mirror also includes an eight
-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.

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.
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.

6-39
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 flash their
high beams at you (for vertical aim). If you believe your
headlamps 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
flat surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat 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.

Allow the headlamps to warm up for one to
two minutes before beginning.

Tires should be properly inflated.

Start the vehicle to level the suspension.
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 under the hood near
the headlamps.
