’hrn and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the
way up or down. The lever returns
automatically when the turn is complete.
I A I 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
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 “Fuses and Circuit Breakers”
in the Index) and check
for burned-out bulbs
if the arrow fails to work when signaling
a turn.
Headlamp High/Low-Beam Changer
Flash-To-Pass
When the headlamps are on,
push the lever to turn the headlamp high beams on, and pull it to the center
position
to turn on the low
beams. This light on the
instrument panel will be on,
indicating high-beam usage.
This lets
you use the high-beam headlamps to signal the
driver in front
of you that you want to pass.
Pull the turn signal lever toward you briefly to
flash-to-pass. 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 low beam, low beam will
remain active and high beam will also illuminate
until you release the lever.

Turn the lamp control once to the right to turn on the
parklamps, taillamps, markerlamps, license lamp and
underhood lamp. The lights
on indicator will be on if the
parklarnp switch
is on. Turn to the left to turn these
lights off.
Lamps On Reminder
You will hear a warning chime if you open the driver’s
door while leaving the lamps on and the manual
headlamp or parklamp control is activated. An exception
to this is when you’re using twilight sentinel, or if the
ignition is
on.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can
be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make the high-beam headlamps
come on at reduced brightness when:
the ignition is on,
When DRL are on, only your high-beam headlamps (at
reduced brightness) 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 switch is
on and it’s dark
enough outside, the high-beam headlamps (at reduced
intensity) will turn off and normal low-beam headlamp
operation will occur. When the twilight sentinel switch
is on and it’s bright enough outside, the regular lamps
will go off, and the high-beam headlamps at reduced
brightness will take over.
If it’s dark outside and the twilight sentinel control is
off, a HEADLAMPS SUGGESTED message will
display on the DIC. This message informs the driver that
turning on the exterior lamps is recommended even
though the DRL are still illuminated. It has become dark
enough outside to require the headlamps and/or other
exterior lamps. Turning on the twilight sentinel or the
headlamp switch will deactivate the
DRL and remove
the HEADLAMPS SUGGESTED message.
If the
parking lamps or the fog lamps were turned on instead,
the DRL will still deactivate and the HEADLAMPS
SUGGESTED message will continue to be displayed.
0 the headlamp switch is off and
0 the transaxle is not in PARK (P).

Downloaded from www.Manualslib.com manuals search engine To idle your vehicle 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 with the DlU 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.
Fog Lamps (STS Only)
Use the fog lamps for better vision in foggy or misty
conditions. When you push the fog lamp switch located
next to the headlamp switch, a small indicator light and
the LIGHTS
ON and FOG LAMP ON telltales on the
instrument panel cluster will tell you that the fog lamps
and the parking lamps
are on. Pushing the fog lamp
switch again will turn them off.
If you switch on the high-beam headlamps, the fog
lamps will turn off. They’ll turn back
on again when you
switch
to low-beam headlamps. You can use the fog
button to turn the fog lamps on or off when the
parklamps
or headlamps are on. When the twilight sentinel
is on and the fog lamp switch
is activated, the
fog lamps, headlamps and parking
lamps will remain
on.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are
on and you signal a turn. They
provide more light for cornering.
Twilight Sentinel
The control is below the
headlamp
knob. It
automatically turns 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 slider control to any position
but
OFF.

The illuminated entry system turns on the courtesy
lamps and the backlighting to the driver's door switches
and to the ignition key when a door is opened or if you
press the
RKE transmitter unlock button. The
illuminated entry system works with the light sensor and
it must be dark outside in order for the courtesy lamps or
backlighting to turn on. The courtesy lamps turn off
approximately
25 seconds after the last door is closed or
after the ignition key is placed in the
RUN position or if
the
RKE transmitter lock button is pressed.
Reading Lamps
The reading lamps are located in the roof. These lamps
and the interior courtesy lamps come on when any door
is opened and it is dark outside. The rear lamps come
on when a rear door
is opened. Press the button to turn
them on. Press it again to turn them off.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the parking lamps are
on. This feature works with the light sensor and is fully
automatic. When the light sensor reads darkness outside,
the instrument panel lights can be adjusted. Backlighting
to the instrument panel will also turn on. If
the reading lamps are left on, they automatically shut
off
10 minutes after the ignition has been turned 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
R€" 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.

Downloaded from www.Manualslib.com manuals search engine Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.
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.
Night Vision
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.
