Section 2 Features and Controls
2-1

One key works all of the
lock cylinders on the
vehicle.
Your vehicle has an Immobilizer Vehicle Theft-Deterrent
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:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
In an emergency, contact Cadillac Roadside Service
®.
SeeRoadside Service on page 7-5.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. SeeOnStar®System (CTS) on
page 2-44for more information.

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 “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System

will ash when you unlock the doors with the remote
keyless entry transmitter. SeeDIC Vehicle
Personalization on page 3-74for more information on

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.
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.

transmitter to resynchronize the transmitter.

Doors and Locks
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 will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not 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 from the outside 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 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.

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 doors.
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.
Delayed Locking
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
delayed locking is active.
When all the doors are closed, the doors will lock
automatically after ve seconds. If a door is reopened
before ve seconds have elapsed, the ve 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 delayed locking 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. SeeDIC Vehicle Personalization on
page 3-74for more information.

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 in the Index.
