2003 CADILLAC DEVILLE ignition

Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transaxle. You may ®nd it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver's seat. To ®nd out how, see
Shifting Into Park (P)
on page 2-34.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transaxle,
so you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is ON. See
Automatic Transaxle Operation
on page 2-27.
If you cannot shift out of PARK (P), ease the pressure
on the shift lever. Push the shift lever all the way
into PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want. If you
ever hold the pedal down but still can't shift out of
PARK (P), try the following:
1. Turn the ignition key to ACCESSORY. Open and
close the driver's door to turn off the RAP feature.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear you
want.
5. Have the vehicle ®xed as soon as you can.

Mirror Operation
O
(On/Off):The on/off button is located on the lower
left side of the mirror face for the automatic dimming and
compass functions of the rearview mirror.
To turn on the automatic dimming feature, press and hold
the on/off button for about three seconds. To turn off
automatic dimming, press and hold the on/off button for
about three seconds again. The indicator light will
illuminate when this feature is active. The automatic
dimming feature is active each time the vehicle is started.
Compass Operation
Press the on/off button once to turn the compass on
or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
If after two seconds, the display does not show a
compass heading (for example, N for North), there may
be a strong magnetic ®eld interfering with the compass.
Such interference may be caused by a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. If the letter C should ever appear in the compass
window, the compass may need calibration.The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button until
a C is shown in the compass display.
Compass Variance
The zone is set to zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain circumstances, as during
a long distance cross-country trip, it will be necessary to
adjust for compass variance. Compass variance is
the difference between earth's magnetic north and true
geographic north. If not adjusted to account for
compass variance, your compass could give false
readings.
To adjust for compass variance do the following:
1. Find the current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.

Sunroof
Your vehicle may have a sunroof. The two switches that
operate the sunroof are located on the overhead
console and include VENT, ROOF, open and close.
Press and hold the ROOF switch rearward to the ®rst
position to open the glass panel and sunshade. The
sunshade also can be opened or closed manually.
To close the glass panel, press and hold the ROOF
switch forward. As the sunroof reaches the closed
position, it will open slightly toward the vent position and
then drop down to the closed position to provide a
better seal.Press and release the ROOF switch rearward to the
second position to express-open the glass panel to the
comfort stop position, approximately half-way open.
The comfort stop position is designed to help reduce
noise and make the rear seat passengers more
comfortable.
The glass panel may then be fully opened by pressing
the ROOF switch again.
If you press and hold and the ROOF switch in the
express-open position for more than one second, the
express-open operation will be over-ridden and the
sunroof will stop when the switch is released.
To stop the glass panel when express opening, press
the ROOF or VENT switch forward or rearward and
release.
To vent the glass panel, press and hold the VENT
switch in the open position. The sunshade must
be opened manually when using the vent position.
To close the glass panel, press and hold the VENT
switch in the close position.
The ROOF and VENT switches work only when the
ignition is on or when RAP is active. See ªRetained
Accessory Powerº under
Ignition Positions on page 2-23.

Vehicle Personalization
Memory Seat, Mirrors and Steering
Wheel
Your vehicle may be
equipped with the memory
package. The controls
for these features
are located on the driver's
door panel, and are
used to program and recall
memory settings for the
driver's seating positions.
Use the following steps to program each button:
1. Adjust the driver's seat including the seatback
recliner, lumbar and head restraint, both outside
mirrors and the steering wheel to a comfortable
position.
2. Press the SET button.
3. Within ®ve seconds, press button 1. After a brief
delay, a single beep will sound through the driver's
side front speaker to let you know that the
position has been stored.A second mirror, seating and steering wheel position
can be programmed by repeating the above steps and
pressing button 2 (for driver 2). Each time a memory
button is pressed, a single beep will sound. Each time
button 1 or 2 is pressed and released while the
vehicle is in PARK (P), the memory positions will be
recalled after a brief delay. If the vehicle is not in PARK
(P), the memory buttons must be pressed and held
to recall the stored positions.
If you use the remote keyless entry transmitter to enter
your vehicle, automatic seat and mirror movement
will occur. The numbers on the back of the transmitters,

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

The exterior lamp control
is located to the left of the
steering wheel on the
instrument panel.
O(Exterior Lamp Control):Turn the control with
this symbol on it to operate the exterior lamps.
The exterior lamp control has three positions:
9(Off):Turn the control to this position to turn off all
lamps except the Daytime Running Lamps (DRL).
;(Parking Lamp):Turn the control to this position
to turn on the parking lamps together with the following:
·Sidemarker Lamps
·Taillamps
·License Plate Lamps
·Instrument Panel Lights
The parking brake indicator light will come on and stay
on while the parking lamps are on with the engine
off and the ignition in ACCESSORY or ON.
5(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
Wiper-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds. To operate, the Twilight
Sentinel
žfeature must be turned on.
When the exterior lamp control is in the off position or
parking lamp position and the wiper control is on delay,
LO or HI, the HEADLAMPS SUGGESTED message
will appear on the Driver Information Center (DIC).
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. The wiper-activated
headlamps will also turn off if the Twilight Sentinel
žor
the windshield wipers are turned off.

Lamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.
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. Fully functional daytime running
lamps are required on all vehicles ®rst sold in Canada.
The DRL system will make the low-beam headlamps
come on at reduced intensity when the following
conditions are met:
·It is still daylight and the ignition is on,
·the exterior lamp control is in the off position and
·the transaxle is not in PARK (P).
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
žlever 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
žlever 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 you start your vehicle in a dark garage, the
automatic headlamp system will come on immediately.
Once you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
knob is in the full bright position. See ªInstrument Panel
Brightnessº under
Interior Lamps on page 3-19.
If it's dark enough outside and the Twilight
Sentinel
žlever is off, a HEADLAMPS SUGGESTED
message will display on the Driver's Information Center
(DIC). This message informs the driver that turning
on the exterior lamps is recommended even though the
DRL are still illuminated.
Turning on the Twilight Sentinel
žor the headlamps 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.
To idle your vehicle with the DRL off at night, turn off the
Twilight Sentinel
žand 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).
