76GETTING TO KNOW YOUR VEHICLE
There is also a second 115 Volt (400 Watts
Maximum) power inverter located on the rear of
the center console. This inverter can power
cellular phones, electronics and other low
power devices requiring power up to 400 Watts.
Certain high-end video game consoles exceed
this power limit, as will most power tools.
All power inverters are designed with built-in
overload protection. If the power rating of
400 Watts is exceeded, the power inverter
shuts down. Once the electrical device has
been removed from the outlet the inverter
should reset.

Rear Center Console Power Inverter Outlet
NOTE:
400 Watts is the maximum for the inverter, not
each outlet. If three outlets are in use, 400 Watts
is shared amongst the devices plugged in.
If equipped with a front bench seat, there may
be a 115 Volt (400 Watts Maximum) inverter
located to the right of the center stack, just
below the climate controls. This inverter can
power cellular phones, electronics and other
low power devices requiring power up to
400 Watts. Certain high-end video game
consoles exceed this power limit, as will most
power tools.

device. The outlet turns off when the device is
unplugged.
NOTE:
The Center Stack Power Inverter is only avail
-
able on vehicles equipped with a front bench
seat.
The power inverter only turns on if the ignition
is in the ACC or ON/RUN position.
Due to built-in overload protection, the power
inverter shuts down if the power rating is
exceeded.
WARNING!
To avoid serious injury or death:
Do not insert any objects into the recepta -
cles.
Do not touch with wet hands.
Close the lid when not in use.

STARTING AND OPERATING175
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
functionality after a battery disconnect.
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
automatically 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.
AUTOSTOP 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.

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
Ú
page 114.

2. The vehicle must be completely stopped.
3. The transmission gear selector must be in DRIVE and the brake pedal pressed.
The engine will shut down, the tachometer will
move to the zero position and the stop/start
telltale will illuminate indicating 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 maintained upon return to an
engine running condition.

SAFETY371
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness.
Check the tires (including spare) for proper cold
inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
EXHAUST GAS The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have an authorized dealer inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each time
the vehicle is raised for lubrication or oil
change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.

460SERVICING AND MAINTENANCE
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. For
these reasons, they wear at unequal rates.
These effects can be reduced by timely rotation
of tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such
as those on all season type tires. Rotation will
increase tread life, help to maintain mud, snow
and wet traction levels and contribute to a
smooth, quiet ride.
For the proper maintenance intervals
Úpage 395. More frequent rotation is
permissible if desired. The reasons for any rapid or unusual wear should be corrected prior to
rotation being performed.
The suggested rotation method is the “rearward
cross” shown in the following diagram. This
rotation pattern does not apply to some
directional tires that must not be reversed.

Tire Rotation (Rearward Cross)

DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer’s if it is less
than 30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION!
