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.
See
Battery on page 10‑28 for
important safety information. If an
airbag has inflated, see What Will
You See after an Airbag Inflates? on
page 3‑31.
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.
See Battery on page 10‑28.
Charging
The high voltage battery can
be charged using a household
electrical outlet. There are three
ways to program how the vehicle
is charged. See Charging on
page 5‑33 for more information.
This section explains the process
for charging the high voltage battery.
Do not allow the vehicle to remain
in temperature extremes for long
periods without being driven or
plugged in. It is recommended that
the vehicle be plugged in when
temperatures are below 0°C (32°F)
and above 32°C (90°F) to maximize
high voltage battery life.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned
off. Additional unexpected clicking
sounds may be experienced caused
by the electrical devices used while
charging.

3-38 Seats and Restraints
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,
seeService Publications Ordering
Information on page 13‑12.
{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
Q: Is there anything I might add
to or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
rollover sensor module, or airbag
wiring can affect the operation of
the airbag system.

Seats and Restraints 3-39
In addition, the vehicle has a
passenger sensing system
for the right front 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 passenger sensing system.
This could either prevent proper
deployment of the passengerairbag(s) or prevent the
passenger sensing system
from properly turning off
the passenger airbag(s).
See
Passenger Sensing
System on page 3‑33.

Procedure on page 13‑1.
If the vehicle has rollover
roof‐rail airbags, see Different
Size Tires and Wheels on
page 10‑65 for additional
important information. Q: Because I have a disability,
I have to get my vehicle
modified. How can I find out
whether this will affect my
airbag system?
A: If you have questions,
call Customer Assistance.
The phone numbers and
addresses for Customer
Assistance are in Step Two
of the Customer Satisfaction
Procedure in this manual.
See Customer Satisfaction
Procedure on page 13‑1.

Instruments and Controls 5-19
Second Row Passenger Safety
Belt Reminder Light
Second row seating positions
monitored for safety belt use
are represented by a colored
symbol indicating safety belt
status. When the vehicle is started,
two safety belt symbols come on
and stay on for several seconds inthe instrument cluster to alert the
driver that passengers may need to
fasten their safety belts. After the
passenger safety belt is buckled,
the corresponding safety belt
symbol in the instrument cluster
turns green. If a safety belt is not
initially buckled, the instrument
cluster displays a red safety belt
symbol. While the vehicle is moving,
if a second row passenger that
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. The system
check includes the airbag sensor,
the pretensioners, the airbag
modules, the wiring, and the crash
sensing and diagnostic module.
For more information on the airbag
system, see
Airbag System on
page 3‑25.
The airbag readiness light comes on
and stays on for several seconds
when the vehicle is started.
Then the light goes out.

Wiring
{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

voltage cable or wiring.
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed.
This greatly reduces the chance
of circuit overload and fire caused
by electrical problems.
Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and other
Power Accessories
Replace a bad fuse with a new one
of the identical size and rating.
