Battery Replacement
Replace the battery if the Replace Battery In Remote
Key message displays in the DIC. See “Replace Battery
In Remote Key” underDIC Warnings and Messages
on page 3-56for additional information.
A weak battery may also cause the DIC to display
Electronic Key Not Detected when you try to start the
vehicle. If this happens, place the transmitter in the
center console storage area transmitter pocket with the
buttons facing to the front of the vehicle. Then, with
the vehicle in PARK (P) or NEUTRAL (N), press
the brake pedal and the ignition control knob. See
Starting the Engine on page 2-35, for additional
information about your vehicle’s electronic keyless
ignition with push start. Although this will start the
vehicle, it is recommended that you replace the
transmitter battery as soon as possible.
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.To replace the battery:
1. Separate the halves of the transmitter with a at,
thin object inserted into the slot on the side or

Remote Vehicle Start
This vehicle may have a remote starting feature that
starts the engine from outside of the vehicle. It may also
start the vehicle’s automatic climate control system.
When the remote start system is active, the climate
control system heats and cools the inside of the vehicle
according to the previous settings of the system
before turning the vehicle off. The windshield defroster
or rear window defogger turn on if it is cold outside.
If the vehicle has heated seats, they also turn on. See
Heated and Ventilated Seats on page 1-6for additional
information. Normal operation of the climate control
system returns after the ignition is turned to ON/RUN.
SeeDual Climate Control System on page 3-24.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if the vehicle is low
on fuel. The vehicle may run out of fuel.
If this vehicle has the remote start feature, the RKE
transmitter functions have an increased range of
operation. However, the range may be less while
the vehicle is running.There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-6orKeyless Access
System on page 2-9for additional information.
/(Remote Start):Press and release the lock button
and then press and hold this button to use the remote
start feature.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the transmitter’s
remote start button until the turn signal lights ash or
if the vehicle’s lights are not visible, press and hold
the remote start button for at least four seconds.
The vehicle’s doors lock. Pressing the remote start
button again after the vehicle has started turns off
the ignition.
When the vehicle starts, the parking lamps turn on
and remain on while the vehicle is running.
3. If it is the rst remote start since the vehicle has
been driven, repeat these steps, while the engine is
still running, to extend the engine running time by
10 minutes. Remote start can be extended one time.
After entering the vehicle during a remote start, press
the brake pedal and turn the ignition to ON/RUN to drive
the vehicle.
2-16

If the vehicle is left running it automatically shuts off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the remote
start button is pressed and held again before the rst
10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote
start buttons are pressed again after ve minutes of
the engine run time, 10 minutes are added and you
now have 15 minutes of engine running. The added
ten minutes are considered a second remote vehicle
start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the keyless access ignition control knob before
the remote start feature can be used again.The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.
A keyless access transmitter is inside the vehicle.
The hood is open.
There is an emission control system malfunction.
The remote start feature is not enabled.
See “Remote Start” underDIC Vehicle
Customization on page 3-69.
The engine turns off during a remote vehicle start if the
coolant temperature gets too high, or the oil pressure
is too low.
This vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).
See “Remote Start” underDIC Vehicle Customization
on page 3-69for additional information.
SeeEngine Exhaust on page 2-48for important safety
information when using remote start in a closed garage.

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the Remote Keyless Entry
(RKE) or Keyless Access System transmitter, if
the vehicle has one, the power door lock switch,
or the rear door manual lock.
2. 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. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If the power door lock switch is pressed when the key
is in the ignition and a door is open, all the doors will lock
and only the driver’s door will unlock. If you close the
doors, they can be locked by using the Remote Keyless
Entry (RKE) 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 RKE transmitter or by pressing the power
lock switch a second time.
On vehicles with a Keyless Access System, the system
can be programmed to alert you when all the doors
are closed and a transmitter has been left inside of the
vehicle. SeeDIC Vehicle Customization on page 3-69
for more information.
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.

Immobilizer Operation (Key Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The theft-deterrent system is disarmed when the key is
turned to ON/RUN.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The key uses a transponder that matches an immobilizer
control unit in your vehicle and automatically disarms
the system. 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, there may be
a problem with your theft-deterrent system. 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 5-123. 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/retailer 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 keys can be programmed for the vehicle.
The following procedure is for programming additional
keys only.
To program a new key do the following:
1. Verify that the new key has
1stamped 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/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to
ON/RUN within ve seconds of the ignition being
turned to LOCK/OFF in Step 3.
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.
In an emergency, contact Cadillac Roadside Service.
SeeRoadside Service on page 7-7.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Immobilizer Operation
(Keyless Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is disarmed when the ignition
control knob is pushed in and a valid transmitter is
found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access
transmitters that are matched to an immobilizer control
unit in your vehicle. Only a correctly matched keyless
access transmitter will start the vehicle. If the keyless
access transmitter 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, there may be
a problem with your immobilizer system. Turn the
ignition control knob off and try again.If the ignition control knob does not rotate, and the
keyless access transmitter appears to be undamaged,
try another keyless access transmitter. Or, you may try
placing the transmitter in the transmitter pocket located in
the center console. See “Electronic Key Not Detected”
underDIC Warnings and Messages on page 3-56. At this
time, you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-123. If the ignition control
knob still does not rotate with the other transmitter, your
vehicle needs service. If the ignition control knob does
rotate, the rst transmitter may be faulty. See your
dealer/retailer who can service the theft-deterrent system
and have a new keyless access transmitter programmed
to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-10.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
