Heated and Ventilated
Front Seats
{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns. To
reduce the risk of burns, people
with such a condition should use
care when using the seat heater,
especially for long periods of
time. Do not place anything on
the seat that insulates against
heat, such as a blanket, cushion,
cover, or similar item. This may
cause the seat heater to
overheat. An overheated seat
heater may cause a burn or may
damage the seat.

3-32 Seats and Restraints
.A front outboard passenger
takes his/her weight off of the
seat for a period of time.
.There is a critical problem with
the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the front
outboard passenger frontal airbag,
the off indicator will light and stay lit
as a reminder that the airbag is off.
See Passenger Airbag Status
Indicator on page 5‑15.
The passenger sensing system is
designed to turn on the front
outboard passenger frontal airbag
anytime the system senses that a
person of adult size is sitting
properly in the front outboard
passenger seat.
When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit as a reminder that the
airbag is active. For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not turn
off the front outboard 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.
{WARNING
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. See Airbag Readiness
Light on page 5‑14 for 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 (Front
Passenger Seat) on page 3‑53
orSecuring Child Restraints
(Rear Seat) on page 3‑51.

Seats and Restraints 3-33
5. If, after reinstalling the childrestraint 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.
Also make sure the child
restraint is not trapped under the
vehicle head restraint. If this
happens, adjust the head
restraint. See Head Restraints
on page 3‑2.
6. Restart the vehicle.
The passenger sensing system
may or may not turn off the
airbag for a child in a child
restraint depending upon the
child’s seating posture and body
build. It is better to secure the
child restraint in a rear seat.If the Off Indicator Is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. Use the
following steps to allow the system
to detect that person and enable the
front outboard passenger frontal
airbag:
1. Turn the vehicle off. 2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, seat massagers,
laptops, or other electronic
devices.
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 specific
vehicle. SeeAdding Equipment to
the Airbag-Equipped Vehicle on
page 3‑35 for more information
about modifications that can affect
how the system operates.
A wet seat can affect the
performance of the passenger
sensing system. Here is how:
.The passenger sensing system
may turn off the passenger
airbag when liquid is soaked into
the seat. If this happens, the off indicator will be lit, and the
airbag readiness light on the
instrument panel will also be lit.
.Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will turn on the
passenger airbag while a child
restraint or child occupant is on
the seat. If the passenger airbag
is turned on, the on indicator will
be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. See Airbag
Readiness Light on page 5‑14 for
important safety information.
The on indicator may be lit if an
object, such as a briefcase,
handbag, grocery bag, laptop or
other electronic device, is put on an
unoccupied seat. If this is not
desired remove the object from
the seat.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13‑16.

{WARNING
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. 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 qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal may keep the airbag system
from working properly.
The operation of the airbag system
can also be affected by changing
any parts of the front seats, safetybelts, airbag sensing and diagnostic
module, steering wheel, instrument
panel, roof-rail airbag modules,
ceiling or pillar garnish trim,
overhead console, front sensors,
side impact sensors, airbag wiring,
or the front center console if the
vehicle has a front center airbag.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system that
includes sensors as part of the front
outboard passenger 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 thepassenger 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 3‑30.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels on page 10‑54 for
additional information.
If your vehicle needs to be modified
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.

Lighting Features
Entry Lighting
For vehicles with courtesy lamps,
they come on and stay on for a set
time whenever
Kis pressed on the
Remote Keyless Entry (RKE)
transmitter.
If a door is opened, the lamps stay
on while it is open and then turn off
automatically about 20 seconds
after the door is closed. If
Kis
pressed and no door is opened, the
lamps turn off after about
20 seconds.
Entry lighting includes a feature
called theater dimming. With theater
dimming, the lamps do not turn off
at the end of the delay time.
Instead, they slowly dim and then
go out. The delay time is canceled if
the ignition key is turned to ON/RUN
or the power door lock switch is
pressed. The lamps will dim
right away. When the ignition is on, illuminated
entry is inactive, which means the
courtesy lamps will not come on
unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates
the interior for a period of time after
all the doors have been closed.
The ignition must be off for delayed
entry lighting to work. Immediately
after all the doors have been closed,
the delayed entry lighting feature
continues to work until one of the
following occurs:
.The ignition is in ON/RUN.
.The doors are locked.
.An illumination period of about
25 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period is canceled and
the interior lamps remain on.

Driving and Operating 9-17
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
the ACC/ACCESSORY or
LOCK/OFF position.
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 the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor 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
allow the cranking motor to cool
down. When the engine starts,
let go of the key and accelerator.
If the vehicle starts briefly but
then stops again, repeat these
steps. 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. 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 coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater
should be plugged in at least four
hours before starting. Some models
may have an internal thermostat in
the cord which 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 bundled cord
is located on the driver side of
the engine compartment,
between the engine air cleaner
and the windshield washer fluid
reservoir. See Engine
Compartment Overview on
page 10‑5.
