2006 PONTIAC GRAND PRIX wiring

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if equipped, the power door lock
switch, or by lifting the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
The lockout protection feature makes it more difficult to
lock the key in the vehicle. If the driver’s door is
open while the key is in the ignition, the door cannot be
locked with the power door lock switch.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in
the ignition, or, if the manual door lock pin is used, the
key could still be locked inside the vehicle. Always
remember to take the key with you.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-33.
To unlock and open the trunk from the outside, press the
trunk button on the remote keyless entry transmitter. See
Remote Keyless Entry System Operation on page 2-4.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light indicates if there is an electrical problem.
The system check includes the airbag sensors,
the airbag modules, the wiring, and the diagnostic
module. For more information on the airbag system, see
Airbag System on page 1-52.
This light will come on
when the vehicle is
started, and it will ash for
a few seconds. Then
the light should go out.
This means the system is
functioning properly.
If the airbag readiness light stays on after the vehicle is
started, or comes on as the vehicle is being driven,
the airbag system may not work properly. Have
the vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should ash for a few
seconds when the ignition key is turned to RUN. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Before starting, check the trailer hitch and platform (and
attachments), safety chains, electrical connector,
lamps, tires, and mirror adjustment. If the trailer has
electric brakes, start the vehicle and trailer moving and
then apply the trailer brake controller by hand to be
sure the brakes are working. This lets you check
the electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
when driving the vehicle without a trailer. This can
prevent situations that require heavy braking and
sudden turns.
Passing
More passing distance is needed up ahead when
towing a trailer. And, because the vehicle and trailer are
a good deal longer, distances between any vehicles
that are passed must be greater, before returning to
the proper lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, move that hand
to the left. To move the trailer to the right, move that
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When turning with a trailer, make wider turns than
normal. Do this so the trailer will not strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When towing a trailer, the vehicle may need a different
turn signal asher and/or extra wiring. Check with
your dealer. The arrows on the instrument panel will
ash whenever signaling a turn or lane change. Properly
hooked up, the trailer lamps will also ash, telling
other drivers the vehicle and trailer are about to turn,
change lanes, or stop.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your vehicle
unless you check with your dealer rst. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-65.
Headlamp Wiring
The headlamp circuit is protected by individual fuses in
the underhood fuse block. An electrical overload will
cause the fuse to blow. If this happens, have the
headlamp system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it xed.
Power Windows and Other Power
Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is xed.
5-111

Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
greatly reduces the chance of res caused by electrical
problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure to
replace a bad fuse with a new one of the identical
size and rating. Spare fuses and a fuse puller are
located in the underhood fuse block. SeeUnderhood
Fuse Blocklater in this section.
Instrument Panel Fuse Block
Some fuses are in a fuse
block located on the end
of the instrument panel on
the passenger side.
To get to the fuse block lift up on the side panel. A fuse
usage chart is on the inside of this panel.
