When the passenger sensing
system has turned off the right
front passenger’s frontal airbag and
seat-mounted side impact airbag,
the off indicator will light and stay lit
to remind you that the airbags are
off. SeePassenger Airbag Status
Indicator on page 4-15.
If a child restraint has been installed
and the on indicator is lit, turn
the vehicle off. Remove the child
restraint from the vehicle and
reinstall the child restraint following
the child restraint manufacturer’s
directions and refer toSecuring
Child Restraints (Rear Seat) on
page 1-50orSecuring Child
Restraints (Right Front Seat)
on page 1-53.If, after reinstalling the child restraint
and restarting the vehicle, the on
indicator is still lit, check to make
sure that the vehicle’s seatback is
not pressing the child restraint into
the seat cushion. If this happens,
slightly recline the vehicle’s seatback
and adjust the seat cushion if
possible. Also make sure the child
restraint is not trapped under
the vehicle head restraint. If this
happens, adjust the head restraint.
SeeHead Restraints on page 1-5.
Remove any additional material from
the seat such as blankets, cushions,
seat covers, seat heaters, or seat
massagers before reinstalling or
securing the child restraint.
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.The passenger sensing system is
designed to enable (may inate)
the right front passenger’s frontal
airbag and seat-mounted side impact
airbag anytime the system senses
that a person of adult size is sitting
properly in the right front passenger’s
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
airbags are 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’s frontal
airbag and seat-mounted side impact
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.

If a person of adult-size is sitting
in the right front passenger’s seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,
turn the vehicle off, remove any
additional material from the seat,
such as blankets, cushions, seat
covers, seat heaters or seat
massagers and ask the person
to place the seatback in the fully
upright position, then sit upright
in the seat, centered on the seat
cushion, with the person’s legs
comfortably extended. Restart the
vehicle and have the person remain
in this position for two to three
minutes. This will allow the system
to detect that person and then enable
the right front passenger’s frontal
airbag and seat-mounted side
impact airbag.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 4-14for 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 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,
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). See
Passenger Sensing System
on page 1-30.

the seat cushion. If this happens,
slightly recline the vehicle’s seatback
and adjust the seat cushion if
possible. Also make sure the child
restraint is not trapped under the
vehicle head restraint. If this
happens, adjust the head restraint.Remove any additional material from
the seat such as blankets, cushions,
seat covers, seat heaters or seat
massagers before reinstalling or
securing the child restraint.
If the on indicator is still lit, secure
the child in the child restraint in
a rear seat position in the vehicle

Your vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for a
few seconds or until the vehicle
starts. If the engine does not start
and the key is held in START for
many seconds, cranking will be
stopped after 15 seconds to
prevent cranking motor damage.
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch to
STEERING UNLOCKED/
IGNITION OFF or LOCK/OFF.
Notice:Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain thebattery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after
5-10 seconds, especially in very
cold weather (below 0°F or
−18°C), it could be ooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the oor and holding it there as
you hold the key in START for up
to a maximum of 15 seconds.
Wait at least 15 seconds between
each try, to let the cranking motor
cool down. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briey but then stops again, do
the same thing. 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 Heater
The engine heater can provide
easier starting and better fuel
economy during engine warm-up
in cold weather conditions at or
below−4°F (−20°C). Vehicles with
an engine heater should be plugged
in at least four hours before starting.
8-4 Driving and Operating
ProCarManuals.com

To Use the Engine Heater
1. Turn off the engine.
2. The engine heater connector is
located in the passenger side
lower front grille. Open the cover
and insert the 110-volt AC
adapter delivered in the vehicles
glove box.
3. Plug the other end of the adapter
into a 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 both ends of
the adapter and store the adapter
to prevent damage.
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
If your vehicle has an automatic
transmission, the shift lever is
located on the console between
the seats.
Your vehicle may also have an
electronic shift position indicator that
displays the position of the shift
lever. This indicator is located above
the trip odometer on the instrument
panel cluster.

{CAUTION
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside.
CO could overcome you and
kill you. You cannot see it or
smell it, so you might not know
it is in your vehicle. Clear away
snow from around the base of
your vehicle, especially any
that is blocking the exhaust
pipe. And check around again
from time to time to be sure
snow does not collect there.
Open a window just a little on
the side of the vehicle that is
away from the wind. This will
help keep CO out.Run your engine only as long as you
must. This saves fuel. When you run
the engine, make it go a little faster
than just idle. That is, push the
accelerator slightly. This uses less
fuel for the heat that you get and it
keeps the battery charged. You will
need a well-charged battery to
restart the vehicle, and possibly
for signaling later on with the
headlamps. Let the heater run
for a while.
Then, shut the engine off and close
the window almost all the way to
preserve the heat. Start the engine
again and repeat this only when
you feel really uncomfortable from
the cold. But do it as little as
possible. Preserve the fuel as long
as you can. To help keep warm,
you can get out of the vehicle and
do some fairly vigorous exercises
every half hour or so until help
comes.
If Your Vehicle is
Stuck in Sand, Mud, Ice,
or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 8-30.
{CAUTION
If you let your vehicle’s tires
spin at high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment re or
other damage. Spin the wheels
as little as possible and avoid
going above 35 mph (55 km/h)
as shown on the speedometer.

chains on the vehicle, seeTire
Chains on page 9-59.
