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.

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may have to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down. Of course, applying the brakes
or downshifting into FIRST (1) takes you out of cruise
control. Many drivers find this to be too much trouble
and don't use cruise control on steep hills.
Ending Cruise Control
There are two ways to end cruise control:

Step lightly on the brake pedal.

Move the CRUISE switch to OFF.
Erasing Speed Memory
The cruise control set speed memory is erased when you
turn off the cruise control or the ignition.Exterior Lamps
This control on the left
side of the instrument
panel controls these
lamp systems:

Headlamps

Taillamps

Parking Lamps

Sidemarker Lamps

License Plate Lamp

Underhood Lamp

Fog Lamps (DeVille Concours Only)

Instrument Panel Lights

Interior Courtesy Lamps

the parking and taillamps, sidemarker lamps and
instrument panel lights. Push the control knob all the
way back in to turn the lamps and lights off.
Headlamps

Cluster lighting will dim only when it is dark outside.
The instrument panel backlighting will activate
whenever the lamps or lights or turned on.
Wiper
-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately 20 seconds.
In order to operate the wiper
-activated headlamps, the
Twilight Sentinel
must be turned on. This feature lights
the way in poor weather and it also makes your vehicle
more visible to other drivers. If the wiper
-activated
headlamps are on and the ignition switch is turned off, the
wiper
- activated headlamps will immediately turn off.The wiper
-activated headlamps will deactivate if you
turn off the Twilight Sentinel or if the windshield wipers
have been turned off for a period of one or two seconds.
Lamps on Reminder
You will hear a warning chime if you open any door
while leaving the lamps on, if the manual headlamp
control is activated. An exception to this is when you're
using Twilight Sentinel.
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 low
-beam headlamps
come on at reduced brightness when:

the ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
When DRL are on, only your low
-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.

yellowblue
2-44
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.

2-45 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

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.If you move the control all the way to the right, the
lamps will remain on for approximately three minutes
after the ignition has been turned to OFF or LOCK. If
you move the control so it is just on, the lamps will go
off quickly when you turn the ignition switch out of
RUN. You can adjust the delay time from only a few
seconds to three minutes.
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 (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.
