PONTIAC GRAND PRIX 2007 Owners Manual

Arming with the Power Lock Switch
The vehicle’s content theft-deterrent alarm system
can be activated when the key is removed from
the ignition and the power door lock switch
of either the driver’s or front passenger’s door is
used to lock the vehicle. The door needs to
be in the open position when pressing the power
door lock switch. The alarm system will not
activate if the door is closed and the power door
lock switch is pressed. This system can be
activated through the Driver’s Information
Center (DIC). See “Lock Switch Arm” under the
Personal Programming Mode Screens inDIC
Vehicle Customization on page 226.
When the doors are locked using the power door
lock switch of either front door, the red light,
on top of the instrument panel will start ashing
indicating that the system is arming. After all
the doors are closed there will be a time delay and
then the red light will begin to ash at a very
slow rate indicating the system is armed.
Arming with the Remote Keyless Entry
Transmitter
The alarm system will arm when the remote keyless
entry transmitter is used to lock the doors after the
key is removed from the ignition. The red light will
come on to indicate that the system is arming. After
all doors are closed and locked, and after a time
delay, the red light will begin ashing at a very slow
rate to show the system is armed.
Arming Conrmation
A red light located on top of the instrument panel,
towards the center of the vehicle and near the
windshield, will ash slowly to conrm when
the system is armed.
Disarming with the Remote Keyless
Entry Transmitter
The alarm system will disarm when the remote
keyless entry transmitter is used to unlock
the doors. The red light will go out to show that
the system is disarmed.
101

Disarming with Your Key
The alarm system will disarm when the key is
used to unlock the doors. The red light will stop
ashing when the system is disarmed. If you would
like the key to disarm the alarm system, see
“Personal Programming Mode Screens” underDIC
Vehicle Customization on page 226for more
information.

PASS-Key®III uses a radio frequency transponder
in the key that matches a decoder in your
vehicle.
102

PASS-Key®III Operation
The vehicle is
equipped with
PASS-Key
®III
(Personalized
Automotive Security
System) theft-deterrent
system. PASS-Key
®III
is a passive
theft-deterrent
system.
This means nothing special needs to be done to
arm or disarm the system. It works when the key is
inserted or removed from the ignition.
PASS-Key
®III uses a transponder in the ignition
key that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the
wrong key has been inserted into the ignition, it
shuts down the vehicle’s starter and fuel systems.The starter will not work and fuel will stop owing to
the engine. If someone tries to start the vehicle
again with the wrong key, the vehicle will not start.
Anyone using a trial-and-error method to start the
vehicle will be discouraged to do so because of the
high number of electrical key codes.
When trying to start the vehicle, if the engine does
not start and the STARTING DISABLED DUE TO
THEFT SYSTEM warning message on the Driver
Information Center (DIC) 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 460.Ifthe
engine still does not start with the other key, the
vehicle needs service. If the vehicle does start, the
rst key may be faulty. See your dealer who can
service the PASS-Key
®III to have a new key made.
In an emergency, contact Roadside Assistance.
SeeRoadside Assistance Program on page 498for
more information.
103

It is possible for the PASS-Key®III decoder
to accept the transponder value of a new or
replacement key. Up to 10 keys may be
programmed for the vehicle. If all the programmed
keys are lost or do not operate, see your GM dealer
or a locksmith who can service PASS-Key
®III to
have keys made and programmed to the system.
Canadian Owners: If all the keys are lost or
damaged, only a GM dealer can service
PASS-Key
®III to have new keys made and
programmed to the system.
The following procedure is for programming a new
or replacement key when you have at least one
already programmed key. To program the new key
do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master 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
RUN within ve seconds of removing the
original key.
5. The STARTING DISABLED DUE TO THEFT
SYSTEM warning message on the DIC will
turn off, once the key has been programmed.
It may not be apparent that the SERVICE
THEFT SYSTEM warning message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.
If the STARTING DISABLED DUE TO THEFT
SYSTEM warning message appears and stays on
the DIC while the vehicle is being driven, the
engine will be able to be restarted if it is turned
off. Your PASS-Key
®III system, however, is
not working properly and must be serviced by
your dealer. The vehicle is not protected by
the PASS-Key
®III system at this time.
If the PASS-Key
®III key is lost or stolen, see
your dealer or a locksmith who can service
PASS-Key
®III to have a new key made.
104

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:
Do not drive at any one constant speed, fast
or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
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 breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 324for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
Ignition Positions
The ignition switch is located on the instrument
panel, to the right of the steering column.
There are four different
positions. Insert the key
in the ignition and
turn it to the right for
each position.
9(OFF):This position locks the ignition,
steering wheel and transaxle. It is a theft-deterrent
feature. This is the only position from which the
key can be removed.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
105

ACC (ACCESSORY):This position allows things
like the radio and windshield wipers to operate
while the engine is off.
R(RUN):This position is where the key returns
to after the vehicle is started. With the engine
off, the RUN position displays some of the warning
and indicator lights.
The battery could be drained if you leave the key
in the ACC or RUN position with the engine
off. You may not be able to start your vehicle if
the battery is allowed to drain for an extended
period of time.
/(START):This position starts the engine. Let
go of the key when the engine starts. The key will
return to the RUN for normal driving.
A continuous warning chime will sound and a KEY
IN IGNITION message will display on the Driver
Information Center (DIC) if the key is turned
to OFF or ACC and the driver’s door is opened.
Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
If the vehicle has Retained Accessory
Power (RAP), certain features will continue to
operate for up to 10 minutes after the ignition key
is turned to OFF unless a door is opened.
106

Starting the Engine
Place the transaxle in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position — this is a safety feature.
To restart when you are already moving,
use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. Do not
race the engine immediately after starting it.
Operate the engine and transaxle gently
to allow the oil to warm up and lubricate all
moving parts.Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine will continue
cranking for a few seconds or until the vehicle
starts. If the engine does not start and the
key is held in START for many seconds,
cranking will be stopped after 15 seconds to
prevent cranking motor damage. To prevent
gear damage, this system also prevents
cranking if the engine is already running.
Engine cranking can be stopped by turning the
ignition switch to the ACC or OFF position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.
107

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts briey but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transaxle gently until the
oil warms up and lubricates all moving parts.
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. Any resulting damage
would not be covered by your vehicle’s
warranty.Engine Coolant Heater
The 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.
The vehicle will start easier and get better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum
of four hours prior to starting the vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also
have an internal thermostat in the plug end of the
cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.
108

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located above the engine
air cleaner/lter. SeeEngine Compartment
Overview on page 346for more information on
location.
3. Plug the cord 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, making
sure to keep it away from moving engine parts.
If this is not done, the cord could be damaged.
How long should the coolant heater be kept
plugged in? The answer depends on the outside
temperature, the kind of oil that is in the vehicle,
and some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where the vehicle will be parked.
The dealer can give you the best advice for that
particular area.
Active Fuel Management™
Your vehicle’s engine may be equipped with
Active Fuel Management™. This system allows
the engine to operate on either all or half of
its cylinders, depending on your driving conditions.
When less power is required, such as cruising
at a constant vehicle speed, the system will
operate in the half cylinder mode, allowing your
vehicle to achieve better fuel economy. When
greater power demands are required, such
as accelerating from a stop, passing, or merging
onto a freeway, the system will maintain
full-cylinder operation.
109

Automatic Transaxle Operation
The shift lever for the automatic transaxle is
located on the console between the seats.
Maximum engine speed is limited when the vehicle
is in PARK (P) or NEUTRAL (N) to protect
driveline components from improper operation.
There are several
different positions for
the shift lever.
PARK (P):This position locks the front wheels.
It is the best position to use when the engine
is started because the vehicle cannot 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). See
Shifting Into Park (P) on page 116.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 324.
