2005 Pontiac Grand Prix Owner ManualM

5. The SECURITY 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 SECURITY DISABLED DUE
TO 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 SECURITY 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.
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 speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
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. SeeTowing
a Trailer on page 4-40for more information.
2-21

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). SeeShifting Into Park (P)
on page 2-31. If you are pulling a trailer, see
Towing a Trailer on page 4-40.
Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transaxle shift lock control system. The regular
brakes must be fully applied and the shift control
button, located on the front of the shift lever,
must be pressed before the vehicle can be shifted
from PARK (P) when the ignition is in RUN.
2-25

The vehicle will shift down to the next gear and have
more power.
Notice:If your vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive your vehicle that way, you
could damage the transaxle. Have your vehicle
serviced right away. You can drive in SECOND (2)
when you are driving less than 35 mph (55 km/h)
and AUTOMATIC OVERDRIVE (D) for higher speeds
until then.
THIRD (3):This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (D).
Here are some times THIRD (3) could be used instead
of AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
When driving in non-highway scenarios
(i.e. city streets, etc.).SECOND (2):This position gives the vehicle more
power but lower fuel economy than THIRD (3).
SECOND (2) can be used on hills. It can help control
the vehicle’s speed as it goes down steep mountain
roads, but then you would also want to use the brakes
off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
FIRST (1):This position gives the vehicle even more
power but lower fuel economy than SECOND (2). It can
be used on very steep hills, or in deep snow or mud.
If the shift lever is moved to FIRST (1), the transaxle will
not shift into rst gear until the vehicle is going slowly
enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
2-27

Parking Brake
The parking brake is
located to the left of the
brake pedal near the
driver’s door. To set the
parking brake, hold
the regular brake pedal
down with the right
foot. Push down on the
parking brake pedal,
with the left foot.
To release the parking brake, hold the regular brake
pedal down with the right foot and push the parking
brake pedal with the left foot. When the left foot is lifted,
the parking brake pedal will lift to the released position.
A warning chime will sound if the parking brake is
set, the ignition is on, and the shift lever is not in
PARK (P) or NEUTRAL (N).The brake light will also appear on the instrument panel
cluster when the parking brake is set. It will stay on if
the parking brake does not release fully.
The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If the vehicle is towing a trailer and parked on a hill,
seeTowing a Trailer on page 4-40. That section shows
what to do rst to keep the trailer from moving.
2-30

Shifting Into Park (P)
{CAUTION:
It can be 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.
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, use
the steps that follow. If you are pulling a trailer,
seeTowing a Trailer on page 4-40.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) by holding in the
button on the shift lever and pushing the shift lever
all the way toward the front of the vehicle.
3. Turn the ignition key to OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pushing
the button.
If you can, it means that the shift lever was not fully
locked in PARK (P).
2-31

Running Your Engine While
You Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-33.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the climate control fan is at the highest
setting. One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-28.
{CAUTION:
It can be 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).
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) on page 2-31.
If you are parking on a hill and if you are pulling a trailer,
also seeTowing a Trailer on page 4-40.
2-34

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part
can still work and stop the vehicle. For good braking,
though, both parts should be working well.
This light should come on briey when the ignition
key is turned to RUN. If it does not come on then,
have it xed so it will be ready to warn you if there
is a problem.When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means the vehicle has a brake problem.
The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set and the vehicle is going faster than 5 mph.
SeeDIC Warnings and Messages on page 3-69for
more information.
The brake warning light may also come on when the
brake uid is low. If this occurs, the LOW BRAKE FLUID
message will also appear in the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 3-69for more information.
If the brake warning light comes on while the vehicle
is being driven, pull off the road and stop carefully.
The brake pedal may be harder to push, or it may go
closer to the oor. It may also take the vehicle longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-38. United States
