Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in a rear seat including an infant
riding in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding in a
booster seat. Never put a child in a rear-facing child
restraint in the right front passenger seat unless
your vehicle has the passenger sensing system and/or
an AIR BAG OFF switch and the air bag status
indicator shows off. Never put a rear facing child
restraint in the right front passenger seat unless the air
bag is off. Here's why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because the
back of the rear-facing child restraint would be
very close to the in¯ating air bag. Be sure the air
bag is off before using a rear-facing child
restraint in the right front seat position.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the Passenger Sensing System
and/or AIR BAG OFF switch are designed to
turn off the passenger's frontal air bag under
certain conditions, no system is fail-safe, and
no one can guarantee that an air bag will not
deploy under some unusual circumstance,
even though it is turned off. General Motors
therefore recommends that rear-facing child
restraints be transported in vehicles with a
rear seat that will accommodate a rear-facing
child restraint, whenever possible.
If you secure a forward-facing child restraint in
the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.

To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
Securing a Child Restraint in the
Right Front Seat Position (Regular
and Extended Cab Models)
Your vehicle has a right front passenger air bag. There
is a switch on the instrument panel that you can use
to turn off the right front passenger's air bag when you
need to secure a rear-facing child restraint at the
right front passenger's position. See the following
illustration. Your switch may vary slightly. See
Air Bag
Off Switch on page 1-71for more on this, including
important safety information and illustrations of alternate
switch designs.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because
the back of the rear facing child restraint
would be very close to the in¯ating air bag. Be
sure the air bag is off before using a
rear-facing child restraint in the right front seat
position.
Even though the Passenger Sensing System
and/or AIR BAG OFF switch are designed to
turn off the passenger's frontal air bag under
certain conditions, no system is fail-safe, and
no one can guarantee that an air bag will not
deploy under some unusual circumstance,
even though it is turned off. General Motors
therefore recommends that rear-facing child
restraints be transported in vehicles with a
rear seat that will accommodate a rear-facing
child restraint, whenever possible.

When Should an Air Bag In¯ate?
An air bag is designed to in¯ate in a moderate to severe
frontal, or near-frontal crash. The air bag will in¯ate
only if the impact speed is above the system's designed
ªthreshold level.º
In any particular crash, no one can say whether an air
bag should have in¯ated simply because of the damage
to a vehicle or because of what the repair costs were.
In¯ation is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See
Off-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-22
for more tips on off-road driving.
Single Stage vs. Dual Stage Air Bags
Depending on the weight of your vehicle you will
have either ªSingle Stage Air Bagsº or ªDual Stage Air
Bagsº. Vehicles that have a passenger sensing
system also have dual stage air bags. If the rearview
mirror in your vehicle has a passenger air bag
status indicator printed on it, your vehicle has the
passenger sensing system and therefore, it has dual
stage air bags. If the rearview mirror in your vehicle does
not have a passenger air bag status indicator printedon it, then your vehicle does not have the passenger
sensing system and it has single stage air bags.
See
Passenger Air Bag Status Indicator on page 3-40orPassenger Sensing System on page 1-76.
Dual Stage Air Bags
If your vehicle has frontal air bags with dual stage
deployment, the amount of restraint will adjust according
to crash severity. For moderate frontal impacts, these
air bags in¯ate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level for the
reduced deployment is about 10 to 16 mph
(16 to 25 km/h), and the threshold level for a full
deployment is about 20 to 25 mph (32 to 40 km/h). The
threshold level can vary, however, with speci®c
vehicle design, so that it can be somewhat above or
below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The air bag is not designed to in¯ate in
rollovers, rear impacts, or in many side impacts because
in¯ation would not help the occupant.

This switch should only be turned to AIR BAG OFF if
the person in the right front passenger's position is
a member of a passenger risk group identi®ed by the
national government as follows:
Infant. An infant (less than 1 year old)
must ride in the front seat because:
·
my vehicle has no rear seat;
·my vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
·the infant has a medical condition which, according
to the infant's physician, makes it necessary for the
infant to ride in the front seat so that the driver
can constantly monitor the child's condition.
Child age 1 to 12. A child age 1 to 12 must
ride in the front seat because:
·
my vehicle has no rear seat;
·although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space
is available in the rear seat(s) of my vehicle; or
·the child has a medical condition which, according
to the child's physician, makes it necessary for the
child to ride in the front seat so that the driver
can constantly monitor the child's condition. Canada without Passenger Sensing System
1-73

Medical Condition. A passenger has a
medical condition which, according to his
or her physician:
·
causes the passenger air bag to pose a special risk
for the passenger; and
·makes the potential harm from the passenger air
bag in a crash greater than the potential harm
from turning off the air bag and allowing the
passenger, even if belted, to hit the dashboard or
windshield in a crash.
{CAUTION:
If the right front passenger's air bag is turned
off for a person who isn't in a risk group
identi®ed by the national government, that
person won't have the extra protection of an
air bag. In a crash, the air bag wouldn't be able
to in¯ate and help protect the person sitting
there. Don't turn off the passenger's air bag
unless the person sitting there is in a risk
group.United States with

To turn the right front passenger's air bag on again,
insert your ignition key into the switch, push in,
and move the switch to the ON or AUTO position.
Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key to RUN or START. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. See
Passenger Air Bag Status Indicator on
page 3-40. If your rearview mirror does not have either of
the indicators pictured below, then your vehicle does not
have the passenger sensing system.The passenger sensing system will turn off the right
front passenger's frontal air bag under certain
conditions. The driver's air bag and the side air bags
are not part of the passenger sensing system. In
addition to the passenger sensing system, your vehicle
also has an air bag off switch located on the instrument
panel as required by the government.
The passenger sensing system works with sensors that
are part of the right front passenger's seat and safety
belt. The sensors are designed to detect the presence of
a properly seated occupant and determine if the
passenger's frontal air bag should be enabled (may
in¯ate) or not.

Q:What if I added a snow plow? Will it keep the
air bags from working properly?
A:We've designed our air bag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles equipped
with the optional Snow Plow Prep Package (RPO
VYU). But don't change or defeat the snow
plow's²tripping mechanism.²If you do, it can
damage your snow plow and your vehicle, and it
may cause an air bag in¯ation.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob to the off position to turn off the fan. If
the knob is in off outside air will still enter the vehicle,
and will be directed based on the position of the
mode knob. The temperature can also be adjusted
using the temperature levers.
Turn the right knob clockwise or counterclockwise to
direct the air¯ow inside of your vehicle.To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel vents.
)(Bi-Level):This mode directs half of the air to the
instrument panel vents; then directs most of the
remaining air to the ¯oor vents. A little air is directed
toward the windshield and the side window vents. Cooler
air is directed to the upper vents and warmer air to
the ¯oor vents.
6(Floor):This mode directs most of the air to the
¯oor vents with a little air directed to the windshield and
the side window vents.
h(Recirculation):The recirculation mode is used to
recirculate the air inside of your vehicle. Use this mode to
help prevent outside odors and/or dust from entering your
vehicle or to help cool the air inside of your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. The light on the recirculation button will
illuminate. Recirculation cannot be used in ¯oor, blend or
defrost modes. An indicator on the button will light up,
¯ash three times and turn off when recirculation is
selected in these modes.The air-conditioning compressor
will also come on when this mode is activated. While in
recirculation mode the windows may fog when the
weather is cold and damp. To clear the fog, select either
the blend or defrost mode and increase fan speed.
3-22

Temperature Control
Driver's Side:The lever on the left side of the climate
control panel is used to raise or lower the temperature
on the driver's side of the vehicle. This lever also adjusts
the temperature to the center console outlets (if
equipped).
Passenger's Side:The lever on the right side of the
climate control panel is used to raise or lower the
temperature on the passenger's side of the vehicle.
#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When the button is
pressed, an indicator light will come on and the system
will begin to cool and dehumidify the air inside of your
vehicle. You may notice a slight change in engine
performance when the air conditioning compressor shuts
off and turns on again. This is normal.
Defogging and Defrosting
Fog on the inside of the windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to choose
from to clear fog or frost from your windshield. Use
the defog mode to clear the windows of fog or moisture
and warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
Turn the right knob clockwise or counterclockwise
to select one of the following modes:
-(Defog):This mode directs the air to the ¯oor
outlets, windshield and the side window vents. The air
conditioning compressor will run automatically to
dehumidify the air to prevent window fogging. The
recirculation mode cannot be selected while in the defog
mode.
1(Defrost):This mode directs most of the air to the
windshield and the side window vents, with only a
little air directed to the ¯oor vents. The air conditioning
compressor will run automatically to dehumidify the
air to prevent window fogging. The recirculation mode
cannot be selected while in defrost mode.
Do not drive the vehicle until all the windows are clear.

Operation Tips
·
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
·Keep the air path under the front seats clear
of objects. This helps air to circulate throughout your
vehicle.
·Adding outside equipment to the front of your
vehicle, such as hood-air de¯ectors, etc., may affect
the performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
Dual Automatic Climate Control
System
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also
has a ¯ow-through ventilation system described later in
this section.
You can select different climate control settings for the
driver and passengers.
