Seats and Restraints 123
Securing Child Restraints
(With the Seat Belt in the
Front Passenger Seat)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint0110.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions.
See Passenger Sensing System
0 98 and Passenger Airbag Status
Indicator 0152 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 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.
Secure rear-facing child restraints
in a rear seat, even if the airbag
is off. If you secure a
(Continued)
Warning (Continued)
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.
SeePassenger Sensing System
0 98 for additional information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 0111 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.

Features
Cargo Tie-Downs
There are four cargo tie-downs in
the rear cargo area. These can be
used to strap cargo down and keep
it from moving inside the vehicle.
Convenience Net
Use the convenience net, located in
the rear, to store small loads as far
forward as possible. The net should
not be used to store heavy loads.
Roof Rack System
{Warning
If something is carried on top of
the vehicle that is longer or wider
than the roof rack—like paneling,
plywood, or a mattress —the
wind can catch it while the vehicle
is being driven. The item being
carried could be violently torn off,
and this could cause a collision
and damage the vehicle. Never
carry something longer or wider
than the roof rack on top of the
vehicle unless using a GM
certified accessory carrier.
If equipped, the roof rack can be
used to load items. For roof racks
that do not have crossrails included,
GM Certified crossrails can be
purchased as an accessory. See
your dealer for additional
information.

may occur depending on how long
the windshield washer had been
activated. See Washer Fluid0315
for information on filling the
windshield washer fluid reservoir.

seats, can be configured to
operate using Retained
Accessory Power (RAP) or
battery power modes. If these
power outlets are used while in
the battery power mode, this
could cause interference
between the Remote Keyless
Entry (RKE) transmitter and the
vehicle, and the vehicle may not
start.

. The power outlets in the third
row seat area or in the rear
cargo area are powered at all
times. The power outlets inside
the storage area, on the rear of
the console, or on the bench
seat are only powered when the
ignition is on or in ACC/
ACCESSORY, or when RAP is
active.{Warning
Power is always supplied to the
outlet, if configured accordingly.
Do not leave electrical equipment
plugged in when the vehicle is not
in use because the vehicle could
catch fire and cause injury or
death.
Caution
Leaving electrical equipment
plugged in for an extended period
of time while the ignition is off will
drain the battery. Always unplug
electrical equipment when not in
use and do not plug in equipment
that exceeds the maximum
15 amp rating.
Certain power accessory plugs may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If a problem is experienced, see
your dealer. When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See
Add-On
Electrical Equipment 0294.
Caution
Hanging heavy equipment from
the power outlet can cause
damage not covered by the
vehicle warranty. The power
outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
Power Outlet 110/120-Volt
Alternating Current
If equipped with this power outlet, it
can be used to plug in electrical
equipment that uses a maximum
limit of 150 watts.
For vehicles with a center console,
the 110/120-volt power outlet is on
the rear of the center console.

Instruments and Controls 139
For vehicles with bench seats, the
110/120-volt power outlet is on the
center stack below the climate
controls.
An indicator light on the outlet turns
on to show it is in use. The light
comes on when the ignition is on,
equipment requiring less than 150
watts is plugged into the outlet, and
no system fault is detected.
The indicator light does not come on
when the ignition is off or if the
equipment is not fully seated into
the outlet.
If equipment is connected using
more than 150 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the
indicator light turns off. To reset the
circuit, unplug the item and plug it
back in or turn the ignition off and
then back to on. The power restarts
when equipment using 150 watts or
less is plugged into the outlet and a
system fault is not detected.The power outlet is not designed for
the following, and may not work
properly if they are plugged in:
.
Equipment with high initial peak
wattage, such as
compressor-driven refrigerators
and electric power tools
. Other equipment requiring an
extremely stable power supply,
such as
microcomputer-controlled
electric blankets and touch
sensor lamps
. Medical equipment
Wireless Charging
The vehicle may have wireless
charging on top of the center
console. See Center Console
Storage 0128. The system
operates at 145 kHz and wirelessly
charges one Qi compatible
smartphone. The power output of
the system is capable of charging at
a rate up to 1 amp (5W), as
requested by the compatible
smartphone. See Radio Frequency
Statement 0421.
{Warning
Wireless charging can affect the
operation of an implanted
pacemaker or other medical
devices. If you have one, it is
recommended to consult with
your doctor before using the
wireless charging system.
The vehicle must be on, in ACC/
ACCESSORY, or Retained
Accessory Power (RAP) must be
active. The wireless charging
feature may not correctly indicate
charging when the vehicle is in RAP.
See Retained Accessory Power
(RAP) 0224.
The operating temperature is −20 °C
(−4 °F) to 60 °C (140 °F) for the
charging system and 0 °C (32 °F) to
35 °C (95 °F) for the smartphone.

{Warning
Remove all objects from the
charging pad before charging
your compatible smartphone.
Objects, such as coins, keys,
rings, paper clips, or cards,
between the smartphone and
charging pad will become very
hot. On the rare occasion that the
charging system does not detect
an object, and the object gets
wedged between the smartphone
and charger, remove the
smartphone and allow the object
to cool before removing it from
the charging pad, to prevent
burns.
To charge a compatible smartphone:1. Remove all objects from the charging pad. The system may
not charge if there are any
objects between the
smartphone and charging pad.
2. Place the smartphone face up against the alignment rib on the
charge pad.
To maximize the charge rate,
ensure the smartphone is fully
seated and centered in the
holder with nothing under it.
A thick smartphone case may
prevent the wireless charger
from working, or may reduce the charging performance. See
your dealer for additional
information.
3. The

This indicates that the
smartphone is properly
positioned and charging. If a
