Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the

Section 2 Features and Controls
2-1

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 not 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.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-39.
Trunk Lock Release
The remote trunk release
button is located on the
lower portion of the
driver’s door.
To use this feature, an automatic transmission must be
in PARK (P) or NEUTRAL (N) and your manual
transmission must be in NEUTRAL with the parking
brake set.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the remote
keyless entry transmitter to open the trunk.
If your vehicle is ever without power, you can still
access the trunk area. Use one of the following
procedures to open the trunk manually.
If your vehicle is equipped with the rear seat
pass-through door, do the following:
1. Fold the rear armrest down and open the
pass-through door. See “Rear-Seat Pass Through”
following for more information.
2-12

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.
Your vehicle has a special key that works with the
theft-deterrent system. There is a transponder in the key
head. 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 5-100. 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.
2-20

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 Assistance.
SeeRoadside Service on page 7-6.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 4-39for more information.
2-21

Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
Notice:If your key seems stuck in OFF and you
can’t turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the key
hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.A (OFF):This is the only position in which you can
insert or remove the key. This position locks the
ignition, steering wheel and transmission. It’s a
theft-deterrent feature.
B (ACCESSORY):This position allows you to use
things like the radio and the windshield wipers when the
engine is off. This position will allow you to turn off
the engine, but still turn the steering wheel.
C (ON):This position is for driving. If your vehicle has
an automatic transmission and you turn off the
engine, the transmission will lock. If you need to shift
the transmission out of PARK (P), the ignition key has to
be in ON.
D (START):This position starts the engine.
2-22

3. Insert a narrow, pointed object into the hole in the
steering column cover and press the spring.
4. Then, turn the ignition switch to OFF and remove
the key.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned
from ON to OFF:
Radio
Power Windows
Audio Steering Wheel Controls (if programmed)
Sunroof (Option)
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition key
to ON and then back to OFF.
Starting Your Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
2-24

Manual Transmission
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the oor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a
safety feature.
1. With your foot off the accelerator pedal, turn your
ignition key to START. Then, let go of the key; the
engine will start automatically. The idle speed
will go down as your engine gets warm.
2. If your engine will not start, or starts but then stops,
it could be ooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
oor and holding it there as you turn the key
to START. If the vehicle starts briey but then stops
again, do the same thing.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
Engine Coolant Heater
Your vehicle may be equipped with an engine
coolant heater.
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You’ll get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required.
2-25

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
on the driver’s side of the vehicle near the engine
oil dipstick. SeeEngine Compartment Overview
on page 5-12for more information on location.
You must remove the plastic cap to access
the plug.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
If your vehicle has an automatic transmission, the
shift lever is located on the center console between the
front seats.
There are several different positions for the shift lever.
2-26

PARK (P):This position locks the rear wheels. It’s the
best position to use when you start the engine
because your vehicle can’t move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (P) (Automatic
Transmission) on page 2-36. If you are pulling
a trailer, seeTowing a Trailer on page 4-39.Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. You must fully apply your
regular brakes before you can shift from PARK (P) when
the ignition key is in ON. If you cannot shift out of
PARK (P), ease pressure on the shift lever. Push the shift
lever all the way into PARK (P) while pressing the button
on the shift lever as you maintain brake application. Then
move the shift lever into the gear you wish. SeeShifting
Out of Park (P) (Automatic Transmission) on page 2-38.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered by
your warranty. Shift to REVERSE (R) only after
your vehicle is stopped.
REVERSE (R):Use this gear to back up.
At low vehicle speeds, you can also use REVERSE (R)
to rock your vehicle back and forth to get out of
snow, ice or sand without damaging your transmission.
SeeIf You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-32for additional information.
