High Voltage Safety
Information
{Warning
Exposure to high voltage can
cause shock, burns, and even
death. The high voltage
components in the vehicle can
only be serviced by technicians
with special training.
High voltage components are
identified by labels. Do not
remove, open, take apart,
or modify these components.
High voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring.
This vehicle has a high voltage
battery and a standard 12-volt
battery. If the vehicle is in a crash, the
sensing system may shut down the
high voltage system. When this
occurs, the high voltage battery is
disconnected and the vehicle will
not start. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer.
{Warning
Damage to the high voltage
battery or high voltage system
can create a risk of electric shock,
overheating, or fire.
If the vehicle is damaged from a
moderate to severe crash, flood,
fire, or other event, the vehicle
should be inspected as soon as
possible. Until the vehicle has
been inspected, store it outside at
least 15 m (50 ft) from any
structure or anything that can

burn. Ventilate the vehicle by
opening a window or a door.
Contact Customer Assistance as
soon as possible to determine
whether an inspection is needed.
SeeCustomer Assistance Offices
on page 13-3.
See Battery on page 10-23 for
important safety information. If an
airbag has inflated, see What Will
You See after an Airbag Inflates? on
page 3-24.
Only a trained service technician
with the proper knowledge and tools
should inspect, test, or replace the
high voltage battery. See your
dealer if the high voltage battery
needs service.

Important Information About
Portable Electric Vehicle Charging
.Charging an electric vehicle can
stress a building’ s electrical
system more than a typical
household appliance.
.Before you plug in to any
electrical outlet, have a qualified

3-30 Seats and Restraints
{Warning
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13-11.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 12‐
volt battery is disconnected, an
airbag can still inflate during
improper service. You can be
injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag
system. Be sure to follow proper
service procedures, and make
sure the person performing work
for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal, may keep the airbag system
from working properly. The
operation of the airbag system can
also be affected by changing any
parts of the front seats, safety belts,the airbag sensing and diagnostic
module, steering wheel, instrument
panel, any of the airbag modules,
ceiling or pillar garnish trim,
overhead console, front sensors,
side impact sensors, or airbag
wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard 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

5-16 Instruments and Controls
While the vehicle is moving, if a
second row passenger who was
previously buckled becomes
unbuckled, the corresponding safety
belt symbol will change to flashing
red for several seconds and a chime
may sound.
Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), passenger
sensing system, the pretensioners,
the airbag modules, the wiring, and
the crash sensing and diagnostic
module. For more information on the
airbag system, seeAirbag System
on page 3-19.
The airbag readiness light comes on
for several seconds when the
vehicle is started. If the light does
not come on then, have it fixed
immediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on.
See Airbag System Messages on
page 5-49.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. See Passenger
Sensing System on page 3-25 for
important safety information. The
passenger airbag status indicator is
in the overhead console.
United States
Canada
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds

outlet serviced by a qualified
electrician.
.When outdoors, plug into an
electrical outlet that is
weather-proof while in use.
.Mount the charging cord to
reduce strain on the electrical
outlet/plug.
{Warning
Improper use of portable electric
vehicle charge cords may cause
a fire, electrical shock, or burns,
and may result in damage to
property, serious injury, or death.
.Do not use extension cords,
multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
.Do not use an electrical outlet
that is worn or damaged,
or one that will not hold the
plug firmly in place.

Warning (Continued)
High voltage components are
identified by labels. Do not
remove, open, take apart,
or modify these components.
High voltage cable or wiring has
orange covering. Do not probe,

voltage cable or wiring.
{Warning
It can be dangerous to work on
your vehicle if you do not have
the proper knowledge, service
manual, tools, or parts. Always
follow owner manual procedures
and consult the service manual
for your vehicle before doing any
service work.
If doing some of your own service
work, use the proper service
manual. It tells you much more about how to service the vehicle
than this manual can. To order the
proper service manual, see
Service
Publications Ordering Information
on page 13-11.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Airbag System
Check on page 3-31.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records on
page 11-14.{Caution
Even small amounts of
contamination can cause damage
to vehicle systems. Do not allow
contaminants to contact the fluids,
reservoir caps, or dipsticks.
Hood
To open the hood:
1. Turn the vehicle off before opening the hood. If the vehicle
is on, the engine will start when
the hood is opened. See Electric
Mode on page 9-21 and
Extended Range Mode on
page 9-22.
2. Pull the release handle with this
symbol. It is below the
instrument panel outboard of the
steering wheel.
