Heated Front Seats
{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns
even at low temperatures. 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.On vehicles with heated front seats,
the controls are located on the
center console. To operate the
heated seats the engine must be
running.

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 5‑14for 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 3‑59or
Securing Child Restraints (Right
Front Passenger Seat)
on
page 3‑61. 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.
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.

Seats and Restraints 3-41
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 thesystem 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 specific
vehicle. See Adding Equipment to
the Airbag-Equipped Vehicle
on
page 3‑43for more information
about modifications that can affect
how the system operates.

Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto 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, overhead console, front
sensors, side impact sensors,
rollover sensor module, 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
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 3‑38.
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.
If the vehicle has rollover
roof-rail airbags, see
Different
Size Tires and Wheels
on
page 10‑53for additional
important information.
Q: Because I have a disability, I have to get my vehicle
modified. How can I find out
whether this will affect my
airbag system?
A: 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.
In addition, your dealer/retailer and
the service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.

6-6 Lighting
Lighting Features
Entry Lighting
For vehicles with courtesy lamps,
they come on and stay on for a set
time whenever the unlock symbol is
pressed on the Remote Keyless
Entry (RKE) transmitter, if the
vehicle has one.
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 the unlock
symbol is 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

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.
Delayed Exit Lighting
Delayed exit lighting illuminates the
interior for a period of time after the
key is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
.The ignition is in ON/RUN.
.The power door locks are
activated.
.An illumination period of
20 seconds has elapsed.
