440 STARTING AND OPERATING

After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal will automatically
re-start the vehicle.
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 5 mph (8 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 Electronic Vehicle Information Center (EVIC)/
Driver Information Display (DID) within the Stop/
Start section. Refer to “Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID)”
in “Understanding 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 illumi-
nate indicating you are in an Autostop. While in an
5
STARTING AND OPERATING 447

Autostop, the Climate Controls system may automati-
cally adjust airflow to maintain cabin comfort. Customer
settings will be maintained 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 stop:
•Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• Battery temperature too warm or cold
• The vehicle is on a steep grade •
Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
• HVAC is set to full defrost mode at a high blower
speed
• Engine has not reached normal operating temperature
• Battery discharged
• The transmission is not in DRIVE
• Hood is open
• Vehicle is in 4LO transfer case mode
Other factors which can inhibit AutoStop include: fuel
level, accelerator pedal input, engine temp too high and
steering angle.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
448 STARTING AND OPERATING

After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual. •
Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
544 STARTING AND OPERATING

OFF-ROAD DRIVING TIPS
Care should be taken when attempting to climb steep
hills or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diago-
nally across the hill.
When driving over sand, mud, and other soft terrain,
shift to low gear and drive steadily. Apply the accelerator
slowly to avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.

CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
FUEL SAVER TECHNOLOGY 5.7L/6.4L 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.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the
transmission in PARK.
The foot operated parking brake is located below the
lower left corner of the instrument panel. To apply the
park brake, firmly push the park brake pedal fully. To
release the parking brake, pull the parking brake release
handle.
572 STARTING AND OPERATING

NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light.” •
Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the receiver module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four TPM sensors

will no longer be displayed, and a pressure value will
display in place of the dashes. A system fault can occur
due to any of the following:
•Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains
materials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
General Information
This device complies with Part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions: 1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired op-
eration.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded “regular” gaso-
line having an octane rating of 87. The use
of higher octane premium gasoline will not provide any
benefit over regular gasoline in these engines.
