2009 PONTIAC G8 heater

The passenger sensing system is
designed to turn on (may inate) the
right front passenger frontal airbag
anytime the system senses that
a person of adult size is sitting
properly in the right front passenger
seat. When the passenger sensing
system has allowed the airbags
to be enabled, the on indicator will
light and stay lit to remind you
that the airbag is active.
For some children who have
outgrown child restraints and for very
small adults, the passenger sensing
system may or may not turn off the
right front passenger frontal airbag,
depending upon the person’s seating
posture and body build. Everyone in
the vehicle who has outgrown child
restraints should wear a safety belt
properly — whether or not there is an
airbag for that person.{CAUTION
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away.
SeeAirbag Readiness Light on
page 4-13for more information,
including important safety
information.
If the On Indicator is Lit for a
Child Restraint
If a child restraint has been installed
and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from
the vehicle.
3. Remove any additional items
from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.4. Reinstall the child restraint
following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints
(Rear Seat) on page 1-48or
Securing Child Restraints
(Right Front Seat) on page 1-50.
5. If, after reinstalling the child
restraint and restarting the
vehicle, the on indicator is
still lit, turn the vehicle off.
Then slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to
make sure that the vehicle
seatback is not pushing the child
restraint into the seat cushion.
6. Restart the vehicle.
If the on indicator is still lit,
secure the child in the child
restraint in a rear seat position
in the vehicle, and check
with your dealer/retailer.
Seats and Restraints 1-29

If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in
the right front passenger seat, but
the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,use the following steps to allow the
system to detect that person and
enable the right front passenger
frontal airbag:
1. Turn the vehicle off.
2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
3. Place the seatback in the fully
upright position.
4. Have the person sit upright in the
seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the
person remain in this position for
two to three minutes after the
on indicator is lit.
Additional Factors Affecting
System Operation
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.
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 except when approved
by GM for your specic vehicle.

Adding Equipment to
Your Airbag-Equipped
Vehicle
Q:Is there anything I might add to
or change about the vehicle
that could keep the airbags
from working properly?
A:Yes. If you add things that
change the vehicle’s frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. 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, the
inside rearview mirror, ceiling
headliner or pillar garnish trim,
front sensors, or airbag wiring
can affect the operation of the
airbag system.In addition, the vehicle has a
passenger sensing system for the
right front passenger position,
which includes sensors that are
part of the passenger’s seat.
The passenger sensing system
may not operate properly if the
original seat trim is replaced
with non-GM covers, upholstery
or trim, or with GM covers,
upholstery or trim designed for
a different vehicle. Any object,
such as an aftermarket seat
heater or a comfort enhancing
pad or device, installed under or
on top of the seat fabric, could
also interfere with the operation of
the passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger
Sensing System on page 1-27.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. SeeCustomer
Satisfaction Procedure on
page 12-1.
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:If you have questions, call
Customer Assistance.

addresses for Customer
Assistance are in Step Two

Driving and Operating 8-1

Wait at least 15 seconds between
each try, to allow the cranking
motor to cool. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briey but then stops again,
repeat the procedure. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Notice:The engine is designed
to work with the electronics
in the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.Engine Coolant Heater
The engine coolant heater, if
available, can help in cold weather
conditions at or below 0°F (−18°C)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting your
vehicle. An internal thermostat in the
plug-end of the cord will prevent
engine coolant heater operation at
temperatures above 0°F (−18°C).
To Use The Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is located on
the driver side of the engine
compartment, behind the
air cleaner for V8 models.
The electrical cord is located
on the passenger side of
the engine compartment, behind
the engine compartment fuse
block for V6 models.3. Plug it into a normal, grounded
110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep
it away from moving engine
parts. If you do not it could be
damaged.
Driving and Operating 8-5

The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Automatic Transmission
Operation
The shift lever is located on the
center console between the
front seats.
There are several different positions
for the shift lever. When the
position of the shift lever is changed,a message is shown in the Driver
Information Center (DIC). The
selected gear is magnied in the
DIC, and changes according to the
shift lever’s movement. There
are also messages for Sport Shift
Mode, Normal Shift Mode and Driver
Shift Control.
P (Park):This position locks the
rear 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 the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you have
to. If you have left the engine
(Continued)
CAUTION (Continued)
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, always set the
parking brake and move the shift
lever to P (Park). SeeShifting Into
Park (Automatic Transmission) on
page 8-12. If you are pulling a
trailer, seeTowing a Trailer on
page 9-89.
Make sure the shift lever is fully
in P (Park) before starting the
engine. The vehicle has an
automatic transmission shift lock
control system. Fully apply the brake
pedal rst and then press the shift
lever button before shifting from
P (Park) when the ignition key is in
ON/RUN or ACC/ACCESSORY.
If you cannot shift out of P (Park),
8-6 Driving and Operating

{CAUTION
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is
a leak. If you run the engine, it
could lose all coolant. That could
cause an engine re, and you
could be burned. Get any leak
xed before you drive the vehicle.Notice:Using coolant other
than DEX-COOL
®can cause
premature engine, heater core, or
radiator corrosion. In addition,
the engine coolant could require
changing sooner, at 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.
Engine Coolant
The cooling system in the vehicle is
lled with DEX-COOL®engine
coolant. This coolant is designed to
remain in the vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
seeEngine Overheating on
page 9-20.
Vehicle Service and Care 9-15

What to Use
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
The vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
Gives freezing protection down
to−34°F (−37°C), outside
temperature.
Gives boiling protection up to
265°F (129°C), engine
temperature.
Protects against rust and
corrosion.
Will not damage aluminum parts.
Helps keep the proper engine
temperature.Notice:If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or
additives are used in the vehicle’s
cooling system, the vehicle
could be damaged. Use only the
proper mixture of the engine
coolant listed in this manual
for the cooling system. See
Recommended Fluids and
Lubricants on page 11-12for
more information.
