2004 CADILLAC SEVILLE Owners Manual

When trying to start the
vehicle, if the engine does
not start and the
SECURITY light comes on,
the key may have a
damaged transponder.
Turn the ignition off and try
again.
If the engine does not start, and the key appears to be
undamaged, try another ignition key. At this time,
you may also want to check the fuse. SeeFuses and
Circuit Breakers on page 5-97. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may be
faulty. See your dealer who can service the PASS-Key
®
III to have a new key made.
It is possible for the PASS-Key
®III decoder to learn the
transponder value of a new or replacement key. Up to 10
additional keys may be programmed for the vehicle. This
procedure is for learning additional keys only.Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-Key
®III to
have new keys made. To program additional keys you
will require two current driver’s keys (black in color). You
must add a step to the following procedure. After
Step 2, repeat Steps 1 and 2 with the second current
driver’s key. Then continue with Step 3.
To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the current driver’s key in the ignition
and start the engine. If the engine will not start see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to ON
within 10 seconds of removing the previous key.
5. The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.
6. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
2-23

If you are ever driving and the SECURITY light comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS- Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, contact
your dealer to have a new key made.
In an emergency, contact Cadillac Roadside Assistance.
SeeRoadside Service on page 7-6.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
•Do not drive at any one speed — fast or
slow — for the first 500 miles (805 km). Do not
make full-throttle starts.
•Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
•Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-37for more information.
2-24

Ignition Positions
With the key in the ignition
switch, located on the
instrument panel, you can
turn the key to four
different positions:
Notice:If your key seems stuck in OFF and you
can not turn it, be sure you are using the correct
key; if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of this works, then
your vehicle needs service.
OFF:This is the only position in which you can insert
or remove the key. This position also locks the transaxle.
It’s a theft-deterrent feature.ACC (Accessory):This position lets you use things
like the radio, windshield wipers, power windows
and optional sunroof when the engine is off. Use ACC if
you must have your vehicle in motion while the engine
is off, for example, if your vehicle is being pushed
or towed.
ON:This is the position for driving.
START:This position starts the engine.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned
from ON to OFF:
•Cellular Phone (If Equipped)
•Radio
•Power Windows
•Audio Steering Wheel Controls
•Sunroof (Option)
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another 10
minutes, close all the doors and turn the ignition key to
ON and then back to OFF. If the cellular phone is
being used while retained accessory power is active,
the timer is suspended to avoid interruption of the call.
The timer resets to 10 minutes at the end of the call.
2-25

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about 15
seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it does not start within 10 seconds, hold your key
in START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.3. If your engine still will not start, or starts but then
stops, it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.

Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
A. Engine Oil Dipstick Location
B. Engine Coolant Heater Cord
C. Transaxle Dipstick/Fluid Fill LocationIn very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required.
2-27

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine, behind the transaxle dipstick/fluid fill
location (C) and next to the engine.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a fire. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
Automatic Transaxle Operation
There are several different
positions for the shift lever,
which is located on the
console between the seats.
PARK (P):This position locks the front wheels. It is the
best position to use when you start the engine
because your vehicle cannot move easily.
2-28

{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (P) on
page 2-32. If you are pulling a trailer, see
Towing a Trailer on page 4-37.Ensure the shift lever is fully in PARK (P) before starting
the engine. 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)
while the ignition key is in ON. If you cannot shift the
shift lever all the way into PARK (P), ease pressure on
the shift lever and push the shift lever all the way
into PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. See
Shifting Out of Park (P) on page 2-34.
REVERSE (R):Use this gear to backup.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
Also use this gear to rock your vehicle back and forth to
get out of snow, ice or sand without damaging your
transaxle. SeeIf You Are Stuck: In Sand, Mud, Ice or
Snow on page 4-28for additional information.
2-29

NEUTRAL (N):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is firmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
AUTOMATIC OVERDRIVE (
X):This position is for
normal driving. If you need more power for passing, and
you are:
•Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transaxle. Have your vehicle
serviced right away. You can drive in SECOND (2)
when you are driving less than 35 mph (55 km/h) and
AUTOMATIC OVERDRIVE (D) for higher speeds
until then.
THIRD (3):This position is also used for normal driving,
however, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (
X).
Here are examples for using THIRD (3) instead of
AUTOMATIC OVERDRIVE (
X):
•When driving on hilly, winding roads.
•When going down a steep hill.
SECOND (2):This position gives you more power. You
can use SECOND (2) on hills. It can help control your
speed as you go down steep mountain roads, but then
you would also want to use your brakes off and on.
Notice:Do not shift into SECOND (2) unless you
are going slower than 65 mph (105 km/h), or you can
damage your engine.
FIRST (1):This position gives you even more power
than SECOND (2). You can use it on very steep hills, or
in deep snow or mud.
