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
Pull the turn signal lever all the way toward you and
then release it to change the headlamps from low beam
to high or from high beam to low.
This light 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 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 low beam, they will shift to
high beam and stay there. Pull the lever toward you
to return to low beam.

If the headlamps are on high beam, they will switch
to low beam. To return to high beam, pull the lever
toward you.
Windshield Wipers
WIPER: Turn the band on the turn signal lever to
control the wipers.
MIST: Turn the band toward you and then release it for
a single wiping cycle. For more cycles, hold the band on
MIST longer.LO or HI: Turn the band away from you to either LO
(low speed) or to HI (high speed), depending on the
wiper speed you want.
DELAY: You can set the wiper speed for a long or short
delay between wipes with this setting. Turn the band to
the DELAY position. The closer you move it to LO, the
shorter the delay. (DeVille Only)
OFF: Turn the band to OFF to turn off the wipers.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If the blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Rainsense Wipers (DeVille d'Elegance
and DeVille Concours Only)
This moisture sensor is mounted on the passenger's
interior side of the windshield behind the rearview
mirror and is used to automatically operate the wipers
by monitoring the amount of moisture that is on
the windshield.

When the Twilight Sentinel switch is on and it's dark
enough outside, the low
-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 low
-beam headlamps at reduced
brightness will take over for the DRL.
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 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 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.
Fog Lamps (DeVille Concours Only)
Use the fog lamps for better
vision in foggy or misty
conditions. When you press
the fog lamp button, a small
indicator light will tell you
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.

Here are some tips on night driving.

Drive defensively.

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.

5. Reinstall the headlamp housing socket back into the
headlamp assembly.Headlamp Aiming
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.
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.
