If the retractor is not
locked, repeat
Steps 4 and 5.
6. 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) 080.
7. Before placing a child in the child restraint, make
sure it is securely held in
place. To check, grasp the
child restraint at the seat
belt path and attempt to
move it side to side and
back and forth. When the
child restraint is properly
installed, there should be
no more than 2.5 cm (1 in)
of movement.
To remove the child restraint,
unbuckle the vehicle seat belt
and let it return to the stowed
position. If the top tether is
attached to a top tether
anchor, disconnect it.Securing Child
Restraints (With the
Seat Belt in the
Front Seat)
This vehicle has airbags.
A rear seat is a safer place to
secure a forward-facing child
restraint. See Where to Put
the Restraint 079.
In addition, the vehicle has a
passenger sensing system
which is designed to turn off
the front outboard passenger
frontal airbag and knee airbag
under certain conditions. See
Passenger Sensing System
0 66 and
Passenger Airbag Status
Indicator 0117 for more
information, including
important safety information.
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 front
outboard passenger frontal
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 front
outboard passenger frontal
airbag inflates and the
passenger seat is in a
forward position.
Even if the passenger
sensing system has turned
off the front outboard
passenger airbag(s), no
system is fail-safe. No one
can guarantee that an
airbag will not deploy under

some unusual circumstance,
even though the airbag(s)
are off.
Secure rear-facing child
restraints in a rear seat,
even if the airbag(s) are off.
If you secure a
forward-facing child
restraint in the front
outboard passenger seat,
always move the seat as far
back as it will go. It is better
to secure the child restraint
in a rear seat.
See Passenger Sensing
System066 for additional
information.
If the child restraint uses a top
tether, see Lower Anchors
and Tethers for Children
(LATCH System) 080 for 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
tether must be anchored.
In Canada, the law requires
that forward-facing child
restraints have a top tether,
and that the tether be
attached.
When using the lap-shoulder
belt to secure the child
restraint in this position, follow
the instructions that came
with the child restraint and the
following instructions:
1. Move the seat as far back as it will go before
securing the
forward-facing child
restraint. Move the seat
upward or the seatback to
an upright position,
if needed, to get a tight
installation of the child
restraint. There must be
finger clearance between
the push button and the
child restraint. When the passenger
sensing system has turned
off the front outboard
passenger frontal airbag
and knee airbag, the OFF
indicator on the passenger
airbag status indicator
should light and stay lit
when you start the vehicle.
See Passenger Airbag
Status Indicator
0117.
2. Put the child restraint on the seat.
3. Pick up the latch plate and run the lap and shoulder
portions of the vehicle
seat belt through or
around the restraint.
Ensure the seat belt
webbing is routed as direct
as possible and is not
caught on seat handles or
plastic trim. The child
restraint instructions will
show you how.

Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
estimates the battery's
temperature and state of
charge. It then adjusts the
voltage for best performance
and extended life of the
battery.
When the battery's state of
charge is low, the voltage is
raised slightly to quickly bring
the charge back up. When thestate of charge is high, the
voltage is lowered slightly to
prevent overcharging. If the
vehicle has a voltmeter gauge
or a voltage display on the
Driver Information Center
(DIC), you may see the voltage
move up or down. This is
normal. If there is a problem,
an alert will be displayed.
The battery can be discharged
at idle if the electrical loads
are very high. This is true for
all vehicles. This is because
the generator (alternator) may
not be spinning fast enough at
idle to produce all the power
that is needed for very high
electrical loads.
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, 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 DIC message
might be displayed. If a battery
message is displayed, it is
recommended that the driver
reduce the electrical loads as
much as possible. See Driver
Information Center (DIC) (Base
Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132.

Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at
the base of the windshield
that could block the flow of
air into the vehicle.
.Clear snow off the hood to
improve visibility and help
decrease moisture drawn
into the vehicle.
.Keep the path under the
front seats clear of objects
to help circulate the air
inside of the vehicle more
effectively.
.Use of non-GM approved
hood deflectors can
adversely affect the
performance of the system.
Check with your dealer
before adding equipment to
the outside of the vehicle.
.Do not attach any devices to
the air vent slats. This
restricts airflow and may
cause damage to the air
vents.
Maintenance
Passenger
Compartment Air
Filter
The filter reduces dust, pollen,
and other airborne irritants
from outside air that is pulled
into the vehicle. The filter
should be replaced as part of
routine scheduled
maintenance. See
Maintenance Schedule0469.
See your dealer regarding
replacement of the filter.
Service
All vehicles have a label
underhood that identifies the
refrigerant used in the vehicle.
The refrigerant system should
only be serviced by trained
and certified technicians. The
air conditioning evaporator
should never be repaired or
replaced by one from a
salvage vehicle. It should only be replaced by a new
evaporator to ensure proper
and safe operation.
During service, all refrigerants
should be reclaimed with
proper equipment. Venting
refrigerants directly to the
atmosphere is harmful to the
environment and may also
create unsafe conditions
based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system
requires periodic maintenance.
