Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if
worn during a more severe crash, then you need
new parts.If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If an airbag in ates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
If the frontal airbags in ate, you will also need to
replace the driver’s and right front passenger’s safety
belt buckle assembly. Be sure to do so. Then the
new buckle assembly will be there to help protect you in
a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt buckle assemblies, even if
the frontal airbags have not deployed. The driver
and front passenger’s safety belt buckle assemblies
contain the safety belt pretensioners. Have your safety
belt pretensioners checked if your vehicle has been
in a collision, or if your airbag readiness light stays on
after you start your vehicle or while you are driving. See
Airbag Readiness Light on page 3-37.

Liftgate
To unlock the liftgate from the outside, turn the key in the
driver’s door cylinder counterclockwise or use the remote
keyless entry transmitter. To lock the liftgate using the
key, turn the key clockwise in the driver’s door.
Open the liftgate using the handle located below the
license plate. Once slightly opened, the liftgate will rise
by itself.{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the liftgate
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
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. SeeDual Climate Control
System on page 3-25.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-33.
To close the liftgate, pull down on the handle, then
rmly shut the liftgate. Don’t drive with the liftgate open,
even slightly. SeeEngine Exhaust on page 2-33.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
The security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent
system.
To arm the system, do the following:
1. Lock the door using the remote keyless entry
transmitter or the power door lock switch.
2. Close all the doors. The security light will illuminate.
It should go off within approximately 30 seconds.If a door or a liftgate is opened without a key or a
remote keyless entry transmitter, the horn will sound
and the lamps will ash for up to 30 seconds.
The theft-deterrent system will not arm if you lock the
doors with a key, use the manual door lock or if
the liftgate is ajar. It activates only if you use the remote
keyless entry transmitter or the power door lock.
To avoid activating the alarm by accident do the
following:The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don’t want to arm the theft-deterrent system.
Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry transmitter disarms the
theft-deterrent system. Unlocking a door any other
way while the system is armed will activate the alarm
when a door or the liftgate is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.
2-17

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.

2-18

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.
2-19

To program a new key do the following:
1. Verify that the new key has PK3+ stamped 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 for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.
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.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Cadillac Roadside Service
®.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines for the rst 500 miles
(805 km):
Do not drive at any one speed, fast or slow.
Do not exceed 70 mph (113 km/h).
Do not make full-throttle starts; also refrain
from using the full throttle while driving.
If these procedures are not followed, your engine,
axle, or other parts could be damaged.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this break-in guideline every
time you get new linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-52for more information.

AUTOMATIC OVERDRIVE (D):This position is for
normal driving. If you need more power for passing,
and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to a lower gear
and have more power.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
FOURTH (4):This position is also used for normal
driving. However, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are examples for using FOURTH (4) instead of
AUTOMATIC OVERDRIVE (D).
When driving on hilly, winding roads.
When going down a steep hill.
This position may also offer improved trailer towing
performance in certain driving conditions.
Driver Shift Control (DSC)
Your automatic transmission has a Driver Shift Control
(DSC) feature that allows you to change gears
similar to a manual transmission. To use the DSC
feature:
1. Slide the shift lever over from AUTOMATIC
OVERDRIVE (D) to the right into the DSC area.
When the transmission is
in DSC mode the sport
mode light in the
instrument panel cluster
will come on.
If you do not move the shift lever forward or
rearward, the vehicle will be in sport mode. While
driving in sport mode, the transmission may remain
in a gear longer than it would in normal driving
mode based on braking, throttle input and vehicle
lateral acceleration.
2. Press the shift lever forward to upshift or rearward
to downshift.
