Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.

If your vehicle has an automatic transmission,
the vehicle must be in PARK (P) to recall
the stored driving positions.
If your vehicle has a manual transmission and the
engine is running, the parking brake must be
set to recall the memory seat driving positions.
The stored driving positions can be recalled
without setting the parking brake if the vehicle
is off.
Press one of the numbered memory buttons to
recall the stored setting. Each time a memory
button is pressed, a single beep will sound.
Three chimes will sound and the setting will not
be recalled if you press button 1 or 2 when
the vehicle is not in PARK (P) on an automatic
transmission or the parking brake is not set on a
manual transmission.If you would like the stored driving positions to be
recalled when unlocking your vehicle with the
Remote Keyless Entry transmitter or after the
key is placed in the ignition, seeDIC Vehicle
Personalization on page 242.
To stop recall movement of the memory feature at
any time, press one of the power seat or mirror
controls.
Two personalized exit positions can also be
programmed. Use the following steps to program
exit positions:
1. Press memory seat button 1 or the unlock
button on the RKE transmitter, that has the
number 1 on the back of it, to recall the
driving position.
2. Adjust the driver’s seat to the desired exit
position.

Two beeps will sound to conrm that the exit
position has been saved.
4. Repeat the procedure for a second driver
using memory seat button 2 or the RKE
transmitter, that has the number 2 on the
back of it.
To recall the stored exit positions, press and
release the exit button. One beep will sound, and
the seat will move to the stored exit position
for that driver. If an exit position has not been
stored for this driver, the seat will move all the way
back. The position of the outside mirrors does
not change for the exit position.If your vehicle has an automatic transmission,
the vehicle must be in PARK (P) to recall the
exit positions. If your vehicle has a manual
transmission and the engine is running, the parking
brake must be set to recall the stored exit
positions.
Three chimes will sound and the exit setting will
not be recalled if you press the exit button when
the vehicle is not in PARK (P) on an automatic
transmission or the parking brake is not set on a
manual transmission.
If you would like your stored exit position to be
recalled when unlocking the vehicle with the
RKE transmitter, or when the ignition is turned

Lockout Protection
If you press the power door lock switch when the
key is in the ignition and any door is open, all
the doors will lock and only the driver’s door will
unlock. If you close the doors, you can lock
them using the remote keyless entry transmitter.
Be sure to remove the key from the ignition
when locking your vehicle.
This feature can be overridden by pressing
the lock button on the remote keyless entry
transmitter or by pressing the power lock switch
a second time.
Trunk
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle.
You cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or
if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle.
See Climate Control System.
If you have air outlets on or under
the instrument panel, open them all
the way.
SeeEngine Exhaust on page 134.

Immobilizer Operation
Your vehicle has a
passive theft-deterrent
system.
The system works when the key is turned to ON.
The key uses a transponder that matches an
immobilizer control unit in your vehicle. Only the
correct key will start the vehicle. 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. SeeFuses and Circuit Breakers on
page 447. If the engine still does not start with the
other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty.
See your dealer who can service the
theft-deterrent system and 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. The following
procedure is for programming additional keys only.
114

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 the security light comes on and stays on while
driving, you will be able to restart the 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

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
for the rst 500 miles (805 km):
Do not drive at any one constant speed,
fast or slow.
Do not exceed 70 mph (113 km/h).
Do not make full-throttle starts; also refrain
from using the full throttle while driving.
Avoid downshifting to brake, or slow,
the vehicle.
If these procedures are not followed, your
engine, axle, or other parts could be damaged.Avoid making hard stops for the rst 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 break-in
guideline every time you get new linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 328for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
