Replacing LATCH System
Parts After a Crash
{WARNING
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint,
resulting in serious injury or even
death in a crash. To help make
sure the LATCH system is
working properly after a crash,
see your dealer to have the
system inspected and any
necessary replacements made
as soon as possible.
If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at the
time of the crash.
Securing Child Restraints
(Rear Outboard Seating
Position)
When securing a child restraint in
a rear seating position, study the
instructions that came with the
child restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for how and
where to install the child restraint
using LATCH. If a child restraint is
secured in the vehicle using a
safety belt and it uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System)
on
page 3‑51for top tether anchor
locations. Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
If the child restraint does not have
the LATCH system, you will be
using the safety belt to secure
the child restraint in this position.
Be sure to follow the instructions
that came with the child restraint.
Secure the child in the child restraint
when and as the instructions say.

3-60 Seats and Restraints
If more than one child restraint
needs to be installed in the rear
seat, be sure to readWhere to Put
the Restraint on page 3‑49.
1. Put the child restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
3. For H3T models, tilt the latchplate to adjust the belt if needed.
4. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.5. For H3 models, pull the rest ofthe shoulder belt all the way out
of the retractor to set the lock.

Seats and Restraints 3-61
6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint,
it may be helpful to use your
knee to push down on the child
restraint as you tighten the belt. 7. If the child restraint has a top
tether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for more
information.
For H3T models, if the headrest
interferes with the installation of
the child restraint, remove the
headrest by pressing the button
on the headrest post, at the
top of the seatback, and lift to
remove. Store the headrest
under the outboard side of the
rear seat.
8. Push and pull the child restraint in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it. If the
headrest has been removed,
reinsert it onto the seatback.
Securing Child Restraints
(Rear Center Seating
Position)
Many child restraints are too wide to
be correctly secured in the center
rear seat, although some of them
will fit there. If the center seat
position is too narrow for the child
restraint, secure it in a rear outside
seat position.
If a child restraint is secured in the
center seat position, follow the
instructions in Securing Child
Restraints (Rear Outboard Seating
Position)
on page 3‑59or Securing
Child Restraints (Rear Center
Seating Position)
on page 3‑61or
Securing Child Restraints (Right
Front Seat Position) on page 3‑62.

3-62 Seats and Restraints
Securing Child Restraints
(Right Front Seat
Position)
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on
page 3‑49.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right front
passenger frontal airbag under
certain conditions. See Passenger
Sensing System
on page 3‑35and Passenger Airbag Status
Indicatoron page 5‑11for more
information, including important
safety information.
A label on the sun visor says,
“Never put a rear-facing child seat
in the front.” This is because the risk
to the rear-facing child is so great,
if the airbag deploys.
{WARNING
A child in a rear-facing child
restraint can be seriously
injured or killed if the right
front passenger airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
(Continued)
WARNING (Continued)
Secure rear-facing child
restraints in a rear seat, even if
the airbag is off. 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.
SeePassenger Sensing System
on page 3‑35for additional
information.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for how and
where to install the child restraint
using LATCH. If a child restraint is
secured using a safety belt and it
uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System)
on page 3‑51for
top tether anchor locations.

Seats and Restraints 3-63
Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as itwill go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag, the off indicator on
the passenger airbag status
indicator should light and stay
lit when the vehicle is started.
See Passenger Airbag Status
Indicator on page 5‑11. 2. Put the child restraint on
the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
4. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
5. Pull the rest of the shoulder beltall the way out of the retractor to
set the lock.

Lighting 6-9
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce
the power demands of some
accessories.Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑18.Battery Power Protection
The dome lamp is shut off if it is left
on for more than 20 minutes when
the ignition is in LOCK/OFF. This
helps to prevent the battery from
being drained.

center and on the side of the
instrument panel to direct the
airflow.
Move the louvers up or down to
change the direction of the airflow.
Use the thumbwheel under the
outlets to change the direction of
the airflow from left to right.Operation Tips.Use the recirculation mode for
maximum air conditioning
performance.
.Clear away any ice, snow or
leaves from the air inlets at the
base of the windshield that may
block the flow of air into the
vehicle.
.Use of non-HUMMER approved
hood deflectors may adversely
affect the performance of the
