2003 PONTIAC GRAND PRIX start

Canadian Owners: If you lose or damage your keys,
only a
GM dealer can service PASS-Key@ Ill to
have new keys made.
To program additional keys, you
will need two current driver’s keys (black in color).
You must add a step to the following procedure. After
Step
2, repeat Steps 1 and 2 with the second current
driver’s key (black
in color). Then continue with Step 3.
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 five seconds
of removing the original 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 Steps 1 through 5 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. Your PASS-Key@ Ill system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key@
Ill system at this time.
If you lose or damage your PASS-Key@ Ill key, see your
dealer or a locksmith who can service PASS-Key@
Ill
to have a new key made.

Starting and Operating Your
Vehicle
New Vehicle Break-In Ignition Positions
With
the key in the ignition switch, you can turn it to
five different positions. The ignition switch is located
on the right side of the steering column.
Notice: Your vehicle doesn’t need an elaborate
“break-in.” But
it will perform better in the long
run if you follow these guidelines:
e
e
e Don’t drive at any one speed - fast or
slow
- for the first 500 miles (805 km).
Don’t make full-throttle starts.
Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren’t 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.
Don’t tow a trailer during break-in.
See “Towing a Trailer”
in the Index for
more information. A
(ACCESSORY): This position lets
you use things like
the radio and windshield wipers while the engine is
off. To use accessory, push in the key and turn it toward
you. The steering wheel will stay locked.
3-1 9

Notice: If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key;
if
so, is it all the way in? 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.
B (LOCK): This position locks the ignition, steering
wheel and transaxle. It’s a theft-deterrent feature. It’s also
the only position from which you can remove the key.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK. Use
OFF if you must have
the vehicle pushed or towed.
D (RUN): This position is where the key returns to after
you start the vehicle. With the engine
off, you can use
RUN to display some of the warning and indicator lights.
E (START): This position starts the engine.
A warning chime will sound
if you open the driver’s door
while the ignition is in
OFF, LOCK or ACCESSORY
and the key is in the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power, (RAP), the power
windows, audio system and sunroof will continue to work
up to
10 minutes after the ignition key is turned to
OFF and none of the doors are opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position - that’s a
safety feature. To restart while you’re already moving,
use NEUTRAL
(N) only.
Nofice: Don’t try to shift to PARK (P) if your
vehicle is moving.
If you do, you could damage the
transaxle. Shift to
PARK (P) only when your
vehicle is stopped.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to
do the following:
Prevent ignition key removal unless the shift lever is
in PARK (P) with the shift lever button fully released.
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than
OFF or
LOCK. The shift lock release is always functional
except in the case
of a dead or low voltage
(less than
9 V) battery.
2-20

If your vehicle has a dead battery or a battery with low
voltage, there is an override access slot that will
allow you to override the shift lock release.
. ": The override access slot is
located on the upper right
side of the console
shift panel.
To use the slot, do the following:
1. Verify that the shift lever is in PARK (P) and that
2. Locate the override access slot on the upper right

unless the shift lever is in the PARK (P) position with
the shift lever button fully released.
Starting Your 3100 V6 Engine
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine gets warm.
Notice: Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor. Wait about
15 seconds
between each try to help avoid draining your battery
or damaging your starter.
2-21

2. If your engine won’t start (or starts but then stops),
it could be flooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key
in START for not more than 15 seconds at a time.
This clears the extra gasoline from the engine.
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 don’t, your engine might not perform properly.
Starting Your 3800 Series II V6 Engine

15 seconds
between each try to help avoid draining your battery
or damaging your starter.
2. If it doesn’t start within 10 seconds, hold your key in
START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.
3. If your engine still won’t start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
This time keep the pedal down for five or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
Notice: Your engine is designed to work with the
electronics in your vehicle.

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
(OOC), use of the coolant
heater
is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located below the engine air
cleaner/filter near the coolant reservoir bottle. See
Engine Comparfment Overview on page
5-12
for more information on location.
3. Plug
it into a normal, grounded 1 IO-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the
wrong kind of extension cord could overheat
and cause a fire. You could be seriously injured. Plug the cord into a properly grounded
three-prong 110-volt
AC outlet. If the cord
won’t 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.
2-23

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 Transaxle Operation
Maximum engine speed is limited when your 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’s
the best position to
use when you start the engine
because the vehicle can’t move easily.
The automatic transaxle has a shift lever on the console
between the seats. There is also a display of the gear
positions on the instrument panel cluster near the
speedometer and tachometer.
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t 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 won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the
shift lever to PARK (P). See “Shifting
Into Park (P)”
in the Index. If you’re pulling a
trailer, see “Towing a Trailer”
in the Index.
2-24

Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transaxle shift lock control system. You must fully apply
the regular brakes and press the shift control button
located on the front of the shift lever, before you
can shift from PARK (P) when the ignition is in RUN.
If you cannot shift out of PARK (P), ease pressure
on the shift lever by pushing
it all the way into PARK (P)
while keeping the brake pedal pushed down. Release
the shift lever button. Then move the shift lever out
of PARK (P), being sure to press the shift lever button.
See Shifting
Out of Park (P) on page 2-30.
REVERSE (R): Use this gear to back up.
Notice: Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transaxle.
Shift to REVERSE (R) only after your vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice or sand without damaging the transaxle, see If
You Are Stuck: In Sand, Mud, ice or Snow on
page
4-32.
NEUTRAL (N): In this position, the engine doesn’t
connect with the wheels. To restart when you’re already
moving, use NEUTRAL (N) only. Also, use
NEUTRAL
(N) when the vehicle is being towed.
ini a d ‘e gea your enc_ e is
“racing” (running at high speed) is dangerous.
Unless your foot
is firmly on the brake pedal,
your vehicle could move very rapidly. You
could lose control and
hit people or objects.
Don’t shift into a drive gear while your engine
is racing.
Notice: Damage to your transaxle caused by
shifting into a drive gear with the engine racing
isn’t
covered by your warranty.
AUTOMATIC OVERDRIVE
(a): This position is for
normal driving. If you need more power
