Section 2 Features and Controls
2-1

There is a master key that works all of the lock cylinders
(driver's door, trunk, ignition and glove box).
There is also a VALET key which only operates the
driver's door and the ignition.
Your vehicle has the PASS-Key
žIII vehicle theft
system. Both the master and VALET key have 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 this
key 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.Any new PASS-Key
žIII key must be programmed
before it will start your vehicle. SeePASS-KeyžIII on
page 2-21for more information on programming
your new key.
Notice:Your vehicle has a number of 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 spare keys.
In an emergency, contact Cadillac Roadside Assistance.
See
Roadside Service on page 7-6.
If your vehicle is equipped with the OnStar
žsystem with
an active subscription and you lock your keys inside
the vehicle, OnStar
žmay be able to send a command to
unlock your vehicle. SeeOnStaržSystem on page 2-45for more information.

frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.

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. Master Key
Valet Key
2-4

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 modi®cations to this system by other than
an authorized service facility could void authorization to

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 ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System

The parking lamps will not ¯ash if they have been
turned on manually. Remote con®rmation is not
operational if a door is open.

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.
Vehicles are delivered with two transmitters. See your
dealer for information on how to obtain additional
transmitters.

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.
1. Use an object like a coin to pry open the transmitter.2. Once the transmitter is separated, use an object
like a pencil to remove the old battery. Do not use
a metal object.
3. Insert the new battery as the instructions under the
cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð 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.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use the
manual lock levers located
at the top of the door
panel near the window.
Push down the manual lock lever to lock the door.
To unlock the door, pull up on the lever.
2-8

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
edge of each rear
door. You must open the
doors to access them.
To use these locks, do the following:
1. Turn the knob located on the passenger's side rear
door clockwise to engage the lock.
2. Close the door.
3. Turn the knob located on the driver's side rear door
counterclockwise to engage the lock.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.When you want to open a rear door while the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the front door power lock switch or
by lifting the rear door manual lock.
2. Then open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Turn the knob on the passenger's side of the rear
door counterclockwise all the way back to the
original position.
3. Turn the knob on the driver's side of the rear door
clockwise all the way back to the original position.
The rear door locks will now work normally.
2-10

Lockout Protection
Leaving your key in any ignition position with any door
open will disable the power door lock switches as
well as the lock button on the remote keyless entry
transmitter. If you close the doors, you can lock them
using the remote keyless entry transmitter. It is
always recommended that you remove the ignition key
when locking your vehicle.
The anti-lockout feature can be overridden by holding
the power door lock switch for three seconds or longer.
Leaving Your Vehicle
If you are leaving your vehicle, open the door, set the
locks from the inside, get out and close the door.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't 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 ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
