1-5 Heated Front Seats (If Equipped)
If your vehicle is equipped
with heated front seats, the
buttons are located on the
climate control panel.There is a button for the driver and one for the front
passenger. Each button has the following three settings:
LO, HI and off. The active setting appears on the
climate control panel display. The LO setting warms the
seatback and cushion until the seat approximates normal
body temperature. The HI setting has a slightly higher
temperature.
To turn on the heated seats, press the button once. The
seat will heat to the HI setting. Press the button again to
switch to the LO setting. Pressing the button a third time
turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press the
button again.

How to Wear Safety Belts Properly
Adults
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different rules
for smaller children and babies. If a child will be riding
in your vehicle, see the part of this manual called
ªChildren.º Follow those rules for everyone's
protection.
First, you'll want to know which restraint systems your
vehicle has.
We'll start with the driver position.
Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see ªSeatsº in the Index.
3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
The shoulder belt may lock if you pull the belt across
you very quickly. If this happens, let the belt go back
slightly to unlock it. Then pull the belt across you
more slowly.

Theft-Deterrent System
The security light is located
on the instrument panel
cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft
-deterrent
system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the remote keyless entry
transmitter or the power door lock switch. The
security light should come on and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.
If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will flash for up to 30 seconds.The theft
-deterrent system won't arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the remote keyless entry
transmitter.
To avoid activating the alarm by accident do the
following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry transmitter disables the
theft
-deterrent system. Unlocking a door any other
way will activate the alarm when a door or the trunk
is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.

2-21
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock switch or the
remote keyless entry transmitter and close the door.
Wait approximately 30 seconds until the security
light goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
exterior lamps will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the
remote keyless entry transmitter or by starting the car
with a valid key.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see ªFuses and Circuit Breakersº in the
Index. If the fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft
-deterrent system when leaving your vehicle.
Immobilizer
Your vehicle is equipped
with a passive
theft
-deterrent system.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation.

2-22
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 modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
The system works when you turn the key to ON (II).
The key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Your vehicle has a special key that works with the
theft
-deterrent system. There is a transponder in the key
head. If the key is ever damaged, you may not be able to
start your vehicle.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 still 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. See ªFuses and
Circuit Breakersº in the Index. 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 theft
-deterrent
system to have a new key made.
It is possible for the theft
-deterrent system 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.

2-23
Canadian Owners: If you lose or damage your keys,
only a GM dealer can service the theft
-deterrent system
to have new keys made. To program additional keys you
will require two current driver's keys. 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 a 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 ten 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.
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. The theft
-deterrent system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
theft
-deterrent system at this time.
In an emergency, contact Cadillac Roadside Assistance.
See ªRoadside Assistanceº in the Index.

New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the
long run if you follow these guidelines for the
first 500 miles (805 km):

Don't drive at any one speed -- fast or slow.

Do not exceed 70 mph (113 km/h).

Don't make full
-throttle starts, also refrain
from using the full throttle while driving.
If these procedures are not followed your engine,
axle or other parts could be damaged.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't 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.
Don't tow a trailer during break-in. See ªTowing
a Trailerº in the Index for more information.
Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
