If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
• 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” in “What To Do In Emergencies” for
further information.
Clearing A Flooded Engine (Using ENGINE
START/STOP Button)
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather procedures,
it may be flooded. To clear any excess fuel: 1. Press and hold the brake pedal.
2. Press the accelerator pedal all the way to the floor and
hold it.
3. Push and release the ENGINE START/STOP button once.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
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 was developed to reduce fuel
consumption. The system will stop the engine automati-
cally during a vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing the accelerator
pedal will automatically restart the engine.
382 STARTING AND OPERATING

Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time, the
system will go into STOP/START READY and if
all other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must Occur:
• The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start section.
Refer to “Instrument Cluster” in “Understanding Your
Instrument Panel” for further information.
• The vehicle must be completely stopped.
• The shifter must be in a forward gear 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
indicating you are in Autostop. 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.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations, the engine
will not stop:
• Driver ’s seat belt is not buckled.
• Driver ’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable
cabin temperature has not been achieved.
• HVAC is set to full defrost mode at a high blower speed.
• HVAC set to MAX A/C.
• Engine has not reached normal operating temperature.
• The transmission is not in a forward gear.
• Hood is open.

STARTING AND OPERATING 383

•Brake pedal is not pressed with sufficient pressure.
Other Factors Which Can Inhibit Autostop Include:
• Accelerator pedal input.
• Engine temp too high.
• 5 MPH threshold not achieved from previous AU-
TOSTOP.
• Steering angle beyond threshold.
• ACC is on and speed is set.
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 conditions of the
items listed above.To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon en-
gine restart.
Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode:
• The transmission selector is moved out of DRIVE.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode.
• HVAC system temperature or fan speed is manually
adjusted.
• Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake pedal appli-
cations).
• STOP/START OFF switch is pressed.
• A STOP/START system error occurs.

ment Panel” for further information.
3. At the next vehicle stop (after turning off the STOP/ START system), the engine will not be stopped. 4. The STOP/START system will reset itself back to an ON
condition every time the ignition is turned off and back
on.
To Manually Turn On The Stop/Start System
Push the STOP/START OFF switch (located on the switch
bank). The light on the switch will turn off.
System Malfunction
If there is a malfunction in the STOP/START system, the
system will not shut down the engine. A “SERVICE STOP/
START SYSTEM” message will appear in the instrument
cluster display within the Stop/Start section. Refer to
“Instrument Cluster” in “Understanding Your Instrument
Panel” for further information.
If the “SERVICE STOP/START SYSTEM” message appears
in the instrument cluster display, have the system checked
by your authorized dealer.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.

STARTING AND OPERATING 385

The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is located:
•3.6L Engine — Coiled and strapped to the engine oil
dipstick tube.
• 5.7L Engine — Bundled and fastened to the injector
harness.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
(Continued)
WARNING! (Continued)
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
park brake, shift the transmission into PARK and,
turn the ignition OFF. When the ignition is in the
OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the park brake, brake pedal or the transmis-
sion gear selector.
• Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave

the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
•Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK (P).
Ignition Park Interlock
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned off. This helps the driver avoid inadvertently leaving the vehicle without placing the trans-
mission in PARK. This system also locks the transmission
in PARK whenever the ignition is in the OFF mode.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed.
The brake pedal must also be pressed to shift from NEU-
TRAL into DRIVE or REVERSE when the vehicle is stopped
or moving at low speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehicle’s
overall fuel economy during normal driving conditions.
Push the “eco” switch in the center stack of the instrument
panel to activate or disable ECO mode. An amber light on
the switch indicates when ECO mode is disabled.
5
STARTING AND OPERATING 387

The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual shifts can
be made using the AutoStick shift control (shift paddles
mounted on the steering wheel). Pressing the shift paddles
(-/+) while in the DRIVE range will manually select the
transmission gear, and will display the current gear in the
instrument cluster. Refer to “AutoStick” in this section for
further information.Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.

STARTING AND OPERATING 389

NOTE:On vehicles equipped with the electronically
shifted transfer case, ensure that the transfer case is in
AWD AUTO or LOW RANGE position on the AWD
Control Switch. Ensure that the NEUTRAL position light is
NOT illuminated.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the ignition OFF.
• Remove the key fob from the vehicle.
WARNING!
•Never use the PARK position as a substitute for the
park brake. Always apply the park brake fully when
parked to guard against vehicle movement and pos-
sible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before leav-
ing the vehicle.

of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the park brake, brake pedal or the transmis-
sion gear selector.
• Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
NOTE:
• Before moving the transmission gear selector out of
PARK, you must start the engine and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
• DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range, as this can damage
the drivetrain.
The following indicators should be used to ensure that you
have engaged the transmission into the PARK position: •
Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
• With brake pedal released, verify that the gear selector
will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must leave the
vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
5
STARTING AND OPERATING 391

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies” for
further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to AutoStick in this section for further information) to
select a lower gear. Under these conditions, using a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup. During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter clutch
is inhibited until the transmission fluid is warm. Normal
operation will resume once the transmission temperature
has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
