2003 Cadillac DeVille Owner ManualM

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's safety
belt properly, seeDriver Position on page 1-14.
The right front passenger's safety belt works the same
way as the driver's safety belt Ð except for one
thing. If you ever pull the lap portion of the belt out all
the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
Center Front Passenger Position
Lap Belt
If your vehicle has a front bench seat, someone can sit
in the center position.
When you sit in the center front seating position, you
have a lap safety belt, which has no retractor. To make
the belt longer, tilt the latch plate and pull it along the belt.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service
manual have information about servicing your vehicle
and the air bag systems. To purchase a service manual,
see
Service Publications Ordering Information on
page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still in¯ate during improper
service. You can be injured if you are close to
an air bag when it in¯ates. Avoid yellow
connectors. They are probably part of the air
bag systems. Be sure to follow proper service
procedures, and make sure the person
performing work for you is quali®ed to do so.
The air bag systems do not need regular maintenance.

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
If they turned the ignition to ACCESSORY or
ON and moved the shift lever out of PARK (P),
that would release the parking brake.
Don't leave the keys in a vehicle with children.
2-3

There is a master key that works all of the lock cylinders
(driver's door, trunk, ignition and glove box).
There is also a VALET key which only operates the
driver's door and the ignition.
Your vehicle has the PASS-Key
žIII vehicle theft
system. Both the master and VALET key have a
transponder in the key head that matches a decoder in
the vehicle's steering column. If a replacement key
or any additional key is needed, you must purchase this
key from your dealer. The key will have PK3 stamped
on it. Keep the bar code tag that came with the original
keys. Give this tag to your dealer if you need a new
key made.Any new PASS-Key
žIII key must be programmed
before it will start your vehicle. SeePASS-KeyžIII on
page 2-21for more information on programming
your new key.
Notice:Your vehicle has a number of features that
can help prevent theft. You can have a lot of trouble
getting into your vehicle if you ever lock your keys
inside. You may even have to damage your vehicle to
get in. So be sure you have spare keys.
In an emergency, contact Cadillac Roadside Assistance.
See
Roadside Service on page 7-6.
If your vehicle is equipped with the OnStar
žsystem with
an active subscription and you lock your keys inside
the vehicle, OnStar
žmay be able to send a command to
unlock your vehicle. SeeOnStaržSystem on page 2-45for more information.
Remote Keyless Entry System
Your keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device. Master Key
Valet Key
2-4

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement is
necessary. See ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System

The parking lamps will not ¯ash, however, if the manual
parking lamps are left on. Remote con®rmation is not
operational if a door is open.
You can program your vehicle so the parking lamps will
not ¯ash and the horn will not sound. For more
information, see
DIC Vehicle Personalization on
page 3-67.
2-5

W(Unlock):Press this symbol to unlock the driver's
door. The parking lamps on your vehicle will ¯ash twice.
The parking lamps will not ¯ash if they have been
turned on manually. Remote con®rmation is not
operational if a door is open.
Press this button again within one to ®ve seconds
to unlock the other doors. It will also disarm the

For more information, see
DIC Vehicle Personalization
on page 3-67andMemory Seat, Mirrors and Steering
Wheel on page 2-55.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Vehicles are delivered with two transmitters. See your
dealer for information on how to obtain additional
transmitters.
2-6

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Use an object like a coin to pry open the transmitter.2. Once the transmitter is separated, use an object
like a pencil to remove the old battery. Do not use
a metal object.
3. Insert the new battery as the instructions under the
cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors aren't locked. So,
wear safety belts properly and lock the
doors whenever you drive.
·Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
·Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
Because your vehicle has the theft-deterrent system,
you must unlock the doors with the key or remote
keyless entry transmitter to avoid setting off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use the
manual lock levers located
at the top of the door
panel near the window.
Push down the manual lock lever to lock the door.
To unlock the door, pull up on the lever.
