2000 CADILLAC DEVILLE Owners Manual

2-44
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin, the
cruise control will automatically disengage. (See
ªTraction Control Systemº in the Index.) When road
conditions allow you to safely use it again, you may turn
the cruise control back on.Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Press the CRUISE ON/OFF button to turn cruise
control on. (The button is located on the bottom left
of the steering wheel.) An indicator light will come
on to show that the cruise control is on.
2. Get up to the speed you want.
3. Press the SET/CST (coast) button. (The button is
located on the bottom right of the steering wheel.)
The CRUISE ENGAGED message will display on
the Driver Information Center (DIC).
4. Remove your foot from the accelerator pedal.

2-45
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
the cruise control. But you don't need to reset it.
Once the vehicle is traveling approximately 25 mph
(40 km/h) or more, you can press RES/ACC
(resume/accelerate) button to return to your desired
preset speed. Also note that the DIC will display the
CRUISE ENGAGED message again.
The vehicle will return to and stay at your preset speed.
If you press and hold the RES/ACC button briefly, the
vehicle speed will increase until you release the button
or apply the brake. Again, unless you want to go faster,
do not press and hold the RES/ACC button.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Press the SET/CST button, then release the button
and the accelerator pedal. You will now cruise at the
higher speed.
Press the RES/ACC button. Hold it there until you
get up to the speed that you want, and then release
the button. To increase your speed in very small
amounts, briefly press the RES/ACC button and then
release it. Each time you do this, your vehicle will
speed up approximately 1 mph (1.6 km/h) faster.
The accelerate feature will only work after you have
set the cruise control speed by pressing the
SET/CST button.
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Press the SET/CST button until you reach the lower
speed you want, then release it. A CRUISE
ENGAGED message will then be displayed in
the DIC.

To slow down in very small amounts, push the
SET/CST button briefly. Each time you do this,
the vehicle will slow down approximately 1 mph
(1.6 km/h).

2-46
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
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. Applying the brake or shifting
into a lower gear will take you out of cruise control. If
you need to apply the brake or shift to a lower gear due
to the grade of the downhill slope, you may not want to
attempt to use your cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the CRUISE ON/OFF button on the
steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.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

2-47
Parking Lamps
Turn the lamp control knob clockwise to the first stop,
to turn on the parking, taillamps, sidemarker lamps. If it
is night, the instrument panel switch backlighting will
also illuminate. Turn the control knob counterclockwise
all the way back to turn the lamps and lights off.
Headlamps
Turn the control knob clockwise all the way to turn on
the parklamps and headlamps. Turn the control knob
counterclockwise to turn the lamps off.
Wiper
-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds.
In order to operate the wiper
-activated headlamps, the
Twilight Sentinel
must be turned on; the ignition key
in the ON position and the windshield wipers on, or in a
delay setting. If the windshield wipers are active while
the ignition key is in ON, but the Twilight Sentinel
switch is off, a ªHeadlamps Suggestedº message will be
displayed on the Driver Information Center. This
message informs the driver that turning on the exterior
lamps is recommended.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, Twilight Sentinel, or the wipers are turned off,
the wiper
-activated headlamps will immediately
turn off.
Lamps on Reminder
If the manual headlamp control is left on and a door is
opened, a warning chime will sound. An exception is
when the Twilight Sentinel function is active.
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.

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.

2-50
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. If you move
the control so it is just on, the lamps will go off quickly
when you turn the ignition switch out of OFF. You can
adjust the delay time from only a few seconds to about
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.Light Sensor
The light sensor for the DRL and the Twilight Sentinel
is located in the center of the front defogger grille. If
you cover the sensor, it will read ªdarkº and the lamps
will come on.

2-51
Exterior Lighting Battery Saver
If the headlamp or manual parking lamp control
has been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is turned to
OFF. This protects draining the battery in case you have
accidentally left the headlamps or parking lamps on. If
you need to purposely leave the lamps on for more than
10 minutes with the ignition in OFF or ACCESSORY,
turn the manual control knob off and then back on.
To delay the lamps from turning off, see ªTwilight
Sentinelº in the Index.
If the headlamp switch is turned on after the ignition key
is moved to either OFF or ACCESSORY, the lamps will
not time out.
Interior Lamps
Instrument Panel
Intensity/Brightness Control
The displays automatically dim when it becomes dark
outside and your lights are on. The displays
automatically brighten when it becomes light outside.
Backlighting will only remain active as long as the
parking lamps are on and it is dark outside.
Courtesy Lamps
The courtesy lamps are located on the ceiling above the
rear seat. These lamps come on with the control lamp
knob or when any door is opened and it is dark outside.
Puddle lamps are located on the bottom of the front and
rear door trim.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the
illuminated entry system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn on.
The courtesy lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.
