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 7-6.
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 on page 2-40
for more information.

Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the remote keyless entry transmitter and
close the door. Wait approximately 30 seconds until
the security light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will ash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers on
page 5-94. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

Immobilizer Operation
Your vehicle is equipped
with a passive
theft-deterrent system.
The system works when you turn the key to ON. The
key uses a transponder that matches an immobilizer
control unit in your vehicle. 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 5-94. 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 to 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. This procedure is for learning additional
keys only.
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.

Service Steering System
Your vehicle may be equipped with a speed variable
assist steering system. SeeSteering on page 4-12.
The Service Steering System message will be displayed
if a problem is detected with the speed variable assist
steering system. When this message is displayed,
you may notice that the effort required to steer
the vehicle increases or feels “heavier,” but you will still
be able to steer the vehicle.

This message is displayed to indicate that the
suspension system is not operating properly. Have your
vehicle serviced at your GM dealer.

This message means there is a problem with the
immobilizer. SeeImmobilizer on page 2-18for more
information. A fault has been detected in the system
which means that the system is disabled and is
not protecting the vehicle. The vehicle usually restarts,
however, you may want to take your vehicle to your
GM dealer before turning off the engine.

This message will appear if the Tire Pressure Monitor
(TPM) system is not working properly. Have your vehicle
serviced at your GM dealer as soon as possible. See
Tire Pressure Monitor System on page 5-61for
more information.

There is a problem with the transmission of your
vehicle. Have your vehicle serviced at your GM dealer.

related powertrain malfunction occurs. Have your vehicle
serviced at your GM dealer as soon as possible.
Speed Limited to XXX
This message indicates that your vehicle speed is
limited to XXX (mph in English mode and km/h in Metric
mode) because the vehicle detects a problem in the
