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. Don't
leave the keys in a vehicle with children.

2-6
One key works all
of the lock cylinders
on the vehicle.
Your vehicle has an Immobilizer vehicle theft system.
The key has 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 it 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.
NOTICE:
Your vehicle has a number of new 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 extra keys.
In an emergency, contact Cadillac Roadside Assistance.
See ªRoadside Assistanceº in the Index.
If your vehicle is equipped with the OnStar system with
an active subscription and you lock your keys inside the
vehicle, OnStar may be able to send a command to
unlock your vehicle. See ªOnStarº in the Index for more
information.

Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- 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. If the
windows are down and the doors are locked, don't reach
in to manually unlock the vehicle because you will set
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 on the door panels
near the windows.
Push down on the manual lock lever to lock the door.
To unlock the door, pull up on the lever.

2-8
Central Door Unlocking System
Your vehicle has a central door unlocking feature. When
unlocking the driver's door, you can unlock the other
doors by holding the key in the turned position for a
few seconds or by quickly turning the key twice in the
lock cylinder.
Power Door Locks
The power door lock
switches are located on
the front door panels.
Press the bottom part of the power door lock switch
to lock or the top of the switch to unlock all the doors
at once.
The rear doors do not have power door lock switches.
You must use the manual levers to lock and unlock the
rear doors when riding in the rear seat.
Last Door Closed Locking Feature
With this feature, you can delay the actual locking of
the doors.
When the power door lock switch or the lock button on
the remote keyless entry transmitter is pressed when the
key is not in the ignition and the driver's door is opened,
a chime will sound three times indicating that last door
closed feature is active.
When all the doors are closed, the doors will lock
automatically after five seconds. If a door is reopened
before five seconds have elapsed, the five second timer
will reset itself once all the doors are closed again.
You can press the door lock switch or the lock button on
the remote keyless entry transmitter again to override
this feature and lock the doors immediately.
You can turn this feature off using the Driver
Information Center (DIC). When the last door closed
locking feature is off, the doors will lock immediately
when you press the power door lock switch or the lock
button on the remote keyless entry transmitter. See
ªVehicle Programming and Personalization Featuresº in
the Index for more information.

2-9
Automatic Door Locks
If your vehicle has an automatic transmission, your
vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved out
of PARK (P), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever back into PARK (P).
If your vehicle has a manual transmission, the doors
will lock automatically after the vehicle speed reaches
5 mph (8 km). The doors will not automatically unlock
until the ignition is turned off and the key is removed
from the ignition switch.
If someone needs to exit the vehicle once the doors have
locked, have that person use the manual lever or power
door lock switch. When the door is closed again, it will
not lock automatically. Use the manual lever or power
lock switch to lock the door.
Programmable Automatic Door Locks
The power door locks can be programmed through
prompts displayed on the Driver Information Center
(DIC). These prompts allow you to choose various
lock and unlock settings. For more information on
programming, see ªVehicle Programming and
Personalization Featuresº in the Index.
Rear-Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security locks
are located on the inside
edge of each rear door. You
must open the rear doors to
access them.
To use these locks, do the following:
1. Insert your key into the slot next to the rear door
security lock label and turn it to engage the lock.
2. Close the door.
3. Repeat the steps for the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.

2-10

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.
The anti
-lockout feature can be overridden by pressing
the lock button on the remote keyless entry transmitter.
Leaving Your Vehicle
If you are leaving your vehicle, open the door, lock the
vehicle from the inside; then get out and close the door.
Remote Keyless Entry System
With this feature, you can lock and unlock the doors or
the trunk and turn on your vehicle's interior lamps from
about 10 feet (3 m) away using the remote keyless entry
transmitter supplied with your vehicle.

2-11
Changes or modifications 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 the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation

doors with the remote keyless entry transmitter. See
ªVehicle Programming and Personalization Featuresº

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.
