2008 Pontiac G5 Owner ManualM

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.
We recommend that you not use seat covers or other
aftermarket equipment other than any that GM has
approved for your specic vehicle. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 1-65for more information about modications that
can affect how the system operates.
{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 7-16.
{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.

4. Insert the key to be programmed and turn it to the
ON/RUN position within ve seconds of the original
key being turned to the LOCK/OFF position.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security light comes on
and stays on, you may be able to restart your engine if
you turn it off. Your PASS-Key
®III+ system, however,
is not working properly and must be serviced by
your dealer/retailer. Your vehicle is not protected by the
PASS-Key
®III+ system at this time.
If you lose or damage your PASS-Key
®III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
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. SeeTowing
a Trailer (Manual Transmission) on page 4-32or
Towing a Trailer (Automatic Transmission) on
page 4-32for the trailer towing capabilities
of your vehicle and more information.
Following break-in, engine speed and load can be
gradually increased.

Automatic Transmission Operation
If your vehicle has an automatic transmission, the
shift lever is located on the console between the seats.
There are several different
positions for the automatic
transmission.
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).
SeeShifting Into PARK (P) (Automatic
Transmission) on page 2-33. If you are pulling
a trailer, seeTowing a Trailer (Manual
Transmission) on page 4-32orTowing a Trailer
(Automatic Transmission) on page 4-32.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have to
fully apply your regular brakes rst and then press
the shift lever button before you can shift from
PARK (P) when the ignition key is in ON/RUN.
2-27

DRIVE (D):This position is for normal driving with the
automatic transmission. It provides the best fuel
economy for your vehicle. If you need more power for
passing, and you are:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push your
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-15.
INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces vehicle speed
without using your brakes for slight downgrades where
the vehicle would otherwise accelerate due to
steepness of grade. If constant upshifting or
downshifting occurs while driving up steep hills, this
position can be used to prevent repetitive types of shifts.
You might choose INTERMEDIATE (I) instead of
DRIVE (D) when driving on hilly, winding roads and
when towing a trailer, so that there is less shifting
between gears.LOW (L):This position reduces vehicle speed more
than INTERMEDIATE (I) without actually using
your brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in LOW (L),
the transmission will not shift into LOW (L) 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 transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
2-29

Shifting Into PARK (P) (Automatic
Transmission)
{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 (Manual
Transmission) on page 4-32orTowing a Trailer
(Automatic Transmission) on page 4-32.To shift into PARK (P), do the following:
1. Hold the brake pedal down with your right foot and
set the parking brake. SeeParking Brake on
page 2-32for more information.
2. Move the shift lever into PARK (P) by holding in the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the key in your hand, your
vehicle is in PARK (P).
2-33

Shifting Out of PARK (P) (Automatic
Transmission)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in PARK (P) with the shift lever button fully
released, and
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in ON/RUN or ACC/
ACCESORY and the regular brake pedal is applied.
The shift lock release is always functional except in the
case of a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-34for more
information.To shift out of PARK (P):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of PARK (P):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift
lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from PARK (P),
consult your dealer/retailer or a professional towing
service.
Parking Your Vehicle
Before leaving your vehicle, fully press the clutch pedal
down, move the shift lever into REVERSE (R), and
rmly apply the parking brake. Once the shift lever has
been placed in REVERSE (R) with the clutch pedal
pressed down, you can turn the ignition key to
OFF/LOCK, remove the key and release the clutch
pedal. SeeManual Transmission Operation on
page 2-30.
2-35

Running the Vehicle While 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 2-36.
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. See
Winter Driving on page 4-20.
{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 the
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) (Automatic
Transmission) on page 2-33.

trailer, also seeTowing a Trailer (Manual Transmission)
on page 4-32orTowing a Trailer (Automatic
Transmission) on page 4-32.
