2007 GMC ACADIA instrument panel

Safety belts help keep the passenger in position
on the seat during vehicle maneuvers and braking,
which helps the passenger sensing system
maintain the passenger airbag status. See “Safety
Belts” and “Child Restraints” in the Index for
additional information about the importance of
proper restraint use.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system. If
this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the airbag(s). SeeAirbag
Readiness Light on page 217for more on
this, including important safety
information.
A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the
exterior of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. See Customer
Satisfaction Procedure.
If your vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on
page 452for additional important information.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, roof-rail airbag modules,
ceiling headliner, and pillar garnish trim, side
impact sensors, rollover sensor module,
or airbag wiring can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers
and addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 518.
Your dealer/retailer and the service manual have
information about the location of the airbag
sensors, sensing and diagnostic module and
airbag wiring.

Liftgate
{CAUTION:
It can be dangerous to drive with the
liftgate 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 liftgate open, or
if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 199.
CAUTION: (Continued)
CAUTION: (Continued)

If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeePower Liftgate on page 110.
If your vehicle has a power liftgate, seePower
Liftgate on page 110.
To unlock the liftgate, use the power door lock
switch or press the door unlock button on
the Remote Keyless Entry (RKE) transmitter twice.
SeeRemote Keyless Entry (RKE) System
Operation on page 100.
To open the liftgate, press the touchpad on the
underside of the liftgate handle. The vehicle must
be in PARK (P) to open the liftgate. To close
the liftgate, use the pull cup or pull strap as an aid.
109

The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate
will not open. The liftgate will resume operation
when the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate still will not
function, your vehicle should be taken to a
dealership for service.

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
PASS-Key
®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you transition the key
to ON, ACCESSORY or START from the OFF
position.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents the
vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.If the engine does not start and the security light
on the instrument panel comes on when trying
to start the vehicle, 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 490. If the engine still does not start with the
other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See
your dealer/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to
learn the transponder value of a new or
replacement key. Up to nine additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.

Ignition Positions
With the key in the ignition, you can turn it to four
different positions.
A (OFF):This is the only position in which you
can remove the key. This position locks the ignition
and transmission.
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.B (ACCESSORY):This position allows you to use
things like the radio and the windshield wipers
while the engine is off. This position will also allow
you to turn off the engine. Use ACCESSORY if
you must have your vehicle in motion while
the engine is off, for example, if your vehicle is
being pushed or towed.
C (ON):This is the position that the switch
returns to after you start your engine and release
the key. The switch stays in ON when the
engine is running. But even when the engine is
not running, you can use ON to operate your
electrical power accessories, and to display some
instrument panel warning lights.
The battery could be drained if you leave the key
in the ACCESSORY or ON 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.
D (START):This position starts the engine. When
the engine starts, release the key. The ignition
switch will return to ON for normal driving.
124

Automatic Transmission Operation
Your vehicle has an electronic shift position
indicator within the instrument panel cluster.
When using the Electronic Range Select Mode a
number will display next to the L, indicating
the current gear that has been selected.
See Electronic Range Select mode in this section
for more information.
Your automatic transmission has a shift lever
located on the console between the seats.
PARK (P):This position locks your front wheels. It
is the best position to use when you start your
engine because your 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 135.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 371.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
