EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system. Failure
to pass could prevent vehicle registration.For states that require an Inspection and Mainte -
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a depleted battery or a battery replace -
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following: 1. Cycle the ignition switch to the ON position, but do not
crank or start the engine.
NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi -
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the igni -
tion or start the engine. This means that your vehicle's
OBD II system is not ready and you should not proceed
to the I/M station.
• The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off position
or start the engine. This means that your vehicle's OBD
II system is ready and you can proceed to the I/M
station.

If your OBD II system is not ready, you should see an autho -
rized dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you may
need to do nothing more than drive your vehicle as you
normally would in order for your OBD II system to update.
A recheck with the above test routine may then indicate that
the system is now ready. Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle oper
-
ation you should have your vehicle serviced before going to
the I/M station. The I/M station can fail your vehicle
because the MIL is on with the engine running.

246 SAFETY
The air bag system must be ready to protect you in a colli-
sion. The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated with
the electrical Air Bag System Components. Your vehicle may
be equipped with the following Air Bag System Compo -
nents:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
• Occupant Classification System Air Bag Warning Light
The ORC monitors the readiness of the electronic
parts of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If the
ignition switch is in the OFF position or in the ACC position,
the air bag system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the instru-
ment panel for approximately four to eight seconds for a
self-check when the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag Warning Light will
turn off. If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will sound to
alert you if the light comes on again after initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnostics
also record the nature of the malfunction. While the air bag

262 SAFETY
However, if you haven’t healed significantly within a few
days, or if you have any blistering, see your doctor imme-
diately.
• As the air bags deflate, you may see some smoke-like parti -
cles. The particles are a normal by-product of the process
that generates the non-toxic gas used for air bag inflation.
These airborne particles may irritate the skin, eyes, nose, or
throat. If you have skin or eye irritation, rinse the area with
cool water. For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If these particles
settle on your clothing, follow the garment manufacturer’s
instructions for cleaning.
Do not drive your vehicle after the air bags have deployed. If
you are involved in another collision, the air bags will not be
in place to protect you. NOTE:
• Air bag covers may not be obvious in the interior trim, but
they will open during air bag deployment.
• After any collision, the vehicle should be taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on
the nature of the event, the ORC will determine whether to
have the Enhanced Accident Response System perform the
following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor (If Equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as the battery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System
• Unlock the power door locks
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assemblies
replaced by an authorized dealer immediately. Also,
have the Occupant Restraint Controller System serviced
as well.

NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g. headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be changed
from ignition START or ON/RUN to ignition OFF. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag system could cause it to fail when you need it. You could be injured
if the air bag system is not there to protect you. Do not
modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
body structure, or add aftermarket side steps or
running boards.

296 STARTING AND OPERATING
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking with
the accelerator pedal pushed all the way to the floor. Release
the accelerator pedal and the ignition button/key once the
engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held to
the floor, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Cold Weather Operation (Below –22°F Or −30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a stan-
dard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
The engine block heater cord is routed under the hood on the
passenger side of the vehicle near the right head lamp
assembly. It is located between the front grill and the radi -
ator, but underneath the black upper seal.
• If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery or
the battery in another vehicle. This type of start can be
dangerous if done improperly. Refer to “Jump Starting
Procedure” in “In Case Of Emergency” for further
information.
CAUTION!
To prevent damage to the starter, do not crank the engine
for more than 10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING! (Continued)
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.

POWER STEERING
Electric Power Steering
The electric power steering system will give you effective
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and proper feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
If the Steering icon is flashing, it indicates that the vehicle
needs to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance.
If the Steering icon is displayed and the “POWER STEERING
SYSTEM OVER TEMP” message is displayed on the instru-
ment cluster screen, they indicate that extreme steering
maneuvers may have occurred which caused an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle idle
for a few moments until the icon and message turn off. Refer
to “Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
If the Steering icon is displayed and the “SERVICE POWER
STEERING – ASSIST OFF” message is displayed the instru-ment cluster screen, they indicate the vehicle needs to be
taken to the dealer for service. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.
NOTE:
• Even if the power steering assistance is no longer opera
-
tional, it is still possible to steer the vehicle. Under these
conditions there will be a substantial increase in steering
effort, especially at low speeds and during parking
maneuvers.
• If the condition persists, see your authorized dealer for service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES ONLY —
IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine's eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE:
This system may take some time to return to full function -
ality after a battery disconnect.

334 STARTING AND OPERATING
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and reduce
emissions. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or shifting out of DRIVE will auto-
matically restart the engine.
Vehicles equipped with eTorque contain a heavy duty motor
generator and an additional hybrid electric battery to store
energy from vehicle deceleration for use on engine startup
after a stop as well as providing launch torque assist.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START NOT
READY until you drive forward with a vehicle speed greater
than 2 mph (3 km/h). At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into an STOP/START AUTO STOP ACTIVE
“Autostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. A STOP/START READY message will be displayed in the instrument cluster within the Stop/Start section. Refer to
“Instrument Cluster Display” in “Getting To know Your
Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in DRIVE and the brake pedal depressed.
The engine will shut down, the tachometer will move to the
zero position and the stop/start telltale will illuminate indi -
cating you are in an Autostop. While in an Autostop, the
Climate Controls system may automatically adjust airflow to
maintain cabin comfort. Customer settings will be main -
tained upon return to an engine running condition.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many safety
and comfort conditions to see if they are fulfilled. In
following situations, the engine will not Autostop:
• Driver’s seat belt is not buckled
• Driver’s door is not closed
• The vehicle is on a steep grade
• Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved
