2003 CADILLAC DEVILLE Owners Manual

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.

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things
that can burn.
Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:
·Your exhaust system sounds strange or
different.
·Your vehicle gets rusty underneath.
·Your vehicle was damaged in a collision.
·Your vehicle was damaged when driving
over high points on the road or over road
debris.
·Repairs weren't done correctly.
·Your vehicle or exhaust system had been
modi®ed improperly.
If you ever suspect exhaust is coming into your
vehicle:
·Drive it only with all the windows down to
blow out any CO; and
·Have your vehicle ®xed immediately.

Running Your Engine While You
Are Parked
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust Ð with CO Ð can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
ªWinter Drivingº in the Index.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake ®rmly set. Your vehicle can
roll. Don't leave your vehicle when the engine
is running unless you have to. If you've left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won't move, even when
you're on fairly level ground, always set your
parking brake after you move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See
Shifting Into Park (P) on page 2-34.
If you are parking on a hill and if you're pulling a trailer,
also see
Towing a Trailer on page 4-34.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
ž
Your vehicle may have an automatic dimming rearview
mirror with OnStaržsystem controls. For more
information about OnStarž, seeOnStaržSystem on
page 2-45.
When the automatic dimming feature is turned on, the
mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the mirror senses
when it is becoming dark outside. Another photocell
built into the mirror face senses when headlamps
are behind you.
At night, when the glare is too bright, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear,
daytime state when the glare is reduced.
Mirror Operation
O
(On/Off):This is the on/off button, located on the
lower left side of the mirror face.
To turn the automatic dimming feature on or off, press
the on/off button. The indicator light will be illuminated
when the automatic dimming feature is on.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Automatic Dimming Rearview Mirror
with OnStar
žand Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
žcontrols. For more information seeOnStaržSystem on page 2-45.
The automatic dimming feature functions the same as
that of the automatic dimming rearview mirror without a
compass. See
Automatic Dimming Rearview Mirror
with OnStaržon page 2-40.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.
2-40

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.
2-41

3. Once the zone number appears in the display,
press the on/off button quickly until the correct
zone number appears in the display. Stop pressing
the button and the mirror will return to normal
operation. If C appears in the compass window, the
compass may need calibration. See
Compass
Calibrationlisted previously.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Outside Power Mirrors
The control on the driver's
door armrest operates both
outside rearview mirrors.
Press (R) on the selector switch to choose the right
mirror or (L) to choose the left mirror. The center position
is off and will not allow the mirrors to move if the
control pad is touched.
To adjust a mirror, press the arrows on the control pad
to move the mirror in the direction you want the
mirror to go. Adjust each mirror so you can see the side
of your vehicle and the area behind your vehicle.
2-42

The mirrors can be manually folded inward to prevent
damage when going through an automatic car wash.
To fold, push the mirror toward the vehicle. To return the
mirror to its original position, push outward. Be sure
to return both mirrors to their original unfolded positions
before driving.
The mirrors also have an arrow on the mirror face that
¯ashes in the direction of the turn when the turn
signal is used. See
Turn Signal/Multifunction Lever on
page 3-8.
The mirrors can also be programmed for personalization
and the parallel parking feature if you have the
optional memory package. For more information, see
Memory Seat, Mirrors and Steering Wheel on page 2-55andDIC Vehicle Personalization on page 3-67.
Outside Automatic Dimming Mirror
If your vehicle is equipped with this feature, the
driver's side mirror will adjust for the glare of headlamps
behind you. This feature is controlled by the on and
off settings on the automatic dimming rearview mirror.
See
Automatic Dimming Rearview Mirror with OnStarž
on page 2-40.
Outside Curb View Assist Mirror
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist mirror
feature. This feature will cause the passenger's mirror
to tilt to a factory programmed position when the vehicle
is in REVERSE (R). This feature may be useful in
allowing you to view the curb when you are parallel
parking.
When the vehicle is shifted out of REVERSE (R) and a
®ve-second delay has occurred, the passenger's
mirror will return to its original position.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used.
This feature can be enabled/disabled through the Driver
Information Center (DIC). See
DIC Vehicle
Personalization on page 3-67for more information.
2-43

Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat. This mirror does not have a dimming
feature.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Heated Mirrors
When you operate the rear window defogger, it also
warms both outside mirrors to help clear them of fog or
ice. See
Dual Climate Control System on page 3-29for more information.
