2008 Pontiac Grand Prix Owner ManualM

Passenger Folding Seatback
{CAUTION:
If you fold the seatback forward to carry longer
objects, such as skis, be sure any such cargo
is not near an airbag. In a crash, an inating
airbag might force that object toward a person.
This could cause severe injury or even death.
Secure objects away from the area in which
an airbag would inate. For more information,
seeWhere Are the Airbags? on page 1-55and
Loading Your Vehicle on page 4-22.
{CAUTION:
Things you put on this seatback can strike and
injure people in a sudden stop or turn, or in a
crash. Remove or secure all items before
driving.If the vehicle has this feature, the front passenger seat
can be folded at for more cargo space.
To fold the front passenger seatback at, pull up on the
lever located on back of the seat. Push the seatback
forward until it locks in place.
To return the seatback to the upright position, pull up on
the lever on the back of the seat. Push the seatback
up until it locks in place.
1-8

{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatback to be sure it is
locked.
Push and pull on the seatback to make sure it is locked.
Rear Seats
Split Folding Rear Seat
Both sides of the rear seatback can be folded down.
This gives direct access to the trunk. Make sure the front
seats are not reclined. If they are, the rear seatback(s)
may not fold down all the way.
Notice:Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.To lower the rear seatback,
pull the tab located on the
outboard side of the
seatback and fold the
seatback forward.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatback to be sure it is
locked.
To raise the rear seatback, lift the seatback up until it
latches. Push and pull on the seatback to be sure it is
locked in position.
The seatbacks should be kept in the upright, locked
position when they are not being used to extend the
cargo area.
1-9

{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their neck
and the safety belt continues to tighten.
Secure any unused safety belts behind the
child restraint so children cannot reach them.
Pull the shoulder belt all the way out of the
retractor to set the lock, if your vehicle has
one, after the child restraint has been installed.
Be sure to follow the instructions of the child
restraint manufacturer.
Notice:Contact between the child restraint LATCH
attachment parts and the vehicle’s safety belt
assembly may cause damage to these parts.
Make sure when securing unused safety belts
behind the child restraint that there is no contact
between the child restraint LATCH attachment parts
and the vehicle’s safety belt assembly.Folding an empty rear seat with the safety belts
secured may cause damage to the safety belt or the
seat. When removing the child restraint, always
remember to return the safety belts to their normal,
stowed position before folding the rear seat.
1. Attach and tighten the lower attachments to the
lower anchors. If the child restraint does not have
lower attachments or the desired seating position
does not have lower anchors, secure the child
restraint with the top tether and the safety belts.
Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on
the child restraint to the lower anchors.
2. If the child restraint manufacturer recommends that
the top tether be attached, attach and tighten the
top tether to the top tether anchor, if equipped.
Refer to the child restraint instructions and
the following steps:
2.1. Find the top tether anchor.
2.2. Pull open the top tether anchor cover to
expose the anchor.
1-44

What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from
the inator. Gas from the inator lls the airbag
causing the bag to break out of the cover and deploy.
The inator, the airbag, and related hardware are all part
of the airbag module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with
roof-rail airbags, there are airbag modules in the ceiling
of the vehicle, near the side windows that have
occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-57for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an Airbag
Inates?
After the frontal airbags inate, they quickly deate, so
quickly that some people may not even realize an
airbag inated. Roof-rail airbags may still be at least
partially inated for some time after they deploy.
Some components of the airbag module may be hot for
several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-58.
The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in the
deated airbags. Airbag ination does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people from
leaving the vehicle.
1-58

The passenger sensing system may suppress the
airbag deployment when liquid soaks into the seat.
If this happens, the off indicator in the passenger airbag
status indicator and the airbag readiness light on the
instrument panel will be lit. The system should resume
normal operation after the seat is allowed to dry. If
the system operates incorrectly after the seat has dried,
have your dealer/retailer check the system.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle and
the airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is turned
off and the battery is disconnected, an airbag
can still inate during improper service. You
can be injured if you are close to an airbag when
it inates. Avoid yellow connectors. They are
probably part of the airbag system. Be sure to
follow proper service procedures, and make
sure the person performing work for you is
qualied to do so.
1-64

Your vehicle may have
a red light located on top
of the instrument panel,
toward the center of
the vehicle and near
the windshield, that will
ash slowly when the
system is armed.
The theft-deterrent alarm system needs to be
activated through the Driver’s Information Center (DIC).
See “Theft Deterrent” under the Personal Programming
Mode Screens inDIC Vehicle Customization on
page 3-89. While armed, the doors will not unlock with
the power door lock switch. The remote alarm will
sound if someone tampers with the trunk or enters
the vehicle without using the Remote Keyless
Entry (RKE) transmitter or key to unlock the doors.
The horn will sound and the headlamps will ash for
up to two minutes. The system will also cut off the fuel
supply, preventing the vehicle from being driven.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 in
DIC Vehicle Customization on page 3-89.
When the doors are locked using the power door
lock switch of either front door, the red light, if your
vehicle has one, 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,
if your vehicle has one, will begin to ash at a very
slow rate indicating the system is armed.
2-19

Arming with the RKE Transmitter
The alarm system will arm when the RKE transmitter
is used to lock the doors after the key is removed
from the ignition. The red light, if your vehicle has
one, 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, if your vehicle
has one, will begin ashing at a very slow rate
to show the system is armed.
Arming Conrmation
Your vehicle may have a red light located on top
of the instrument panel, towards the center of the
vehicle and near the windshield, that will ash
slowly to conrm when the system is armed.
Disarming with the RKE Transmitter
The alarm system will disarm when the RKE transmitter
is used to unlock the doors. The red light, if your
vehicle has one, will go out to show that the system
is disarmed.
Disarming with Your Key
The alarm system will disarm when the key is used
to unlock the doors. The red light, if your vehicle has
one, will stop ashing when the system is disarmed.
If you would like the key to disarm the alarm system,
see “Personal Programming Mode Screens” under
DIC Vehicle Customization on page 3-89for more
information.

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 the 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 4-29for 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.
In order to shift out of PARK (P), ignition must be in the
ON/RUN and the regular brake pedal must be applied.
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 none of
this works, then your vehicle needs service.
9(LOCK/OFF):This position locks the ignition,
steering wheel and transmission. It is a theft-deterrent
feature. This is the only position from which the key
can be removed.
2-23

{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 2-34. If you are pulling a trailer,
seeTowing a Trailer on page 4-29.Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brakes rst and then press the
shift lever button, located on the front of the shift lever,
before you can shift from PARK (P) when the ignition
key is in RUN. If the vehicle cannot be shifted out
of PARK (P), ease pressure on the shift lever by pushing
it all the way into PARK (P) as you maintain brake
application. Then press the shift lever button and move
the shift lever into another gear. SeeShifting Out of
PARK (P) on page 2-35.
REVERSE (R):Use this gear to back up.
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.
To rock the vehicle back and forth to get out of snow,
ice or sand without damaging the transmission, see
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-21.
