264 STARTING AND OPERATING

STARTING PROCEDURES — GASOLINE ENGINES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•Before exiting a vehicle, always shift the automatic
transmission into PARK and apply the parking
brake. Always make sure the keyless ignition node 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. Leaving children 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 parking brake, brake pedal or the 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 of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could

WARNING! (Continued)
operate power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Normal Starting
To Turn On The Engine Using The ENGINE START/
STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
3. The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will disengage
automatically after 10 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.6
STARTING AND OPERATING 265

To Turn Off The Engine Using ENGINE START/STOP
Button
1. Place the gear selector in PARK, then push and releasethe ENGINE START/STOP button.
2. The ignition will return to the OFF mode.
3. If the gear selector is not in PARK, the ENGINE START/ STOP button must be held for two seconds or three short
pushes in a row with the vehicle speed above 5 mph
(8 km/h) before the engine will shut off. The ignition
will remain in the ACC mode until the gear selector is in
PARK and the button is pushed twice to the OFF mode.
If the gear selector is not in PARK and the ENGINE
START/STOP button is pushed once, the instrument
cluster will display a “Vehicle Not In Park” message and
the engine will remain running. Never leave a vehicle
out of the PARK position, or it could roll.
NOTE: If the ignition is left in the ACC or RUN (engine not
running) mode and the transmission is in PARK, the
system will automatically time out after 30 minutes of
inactivity and the ignition will cycle to the OFF mode. ENGINE START/STOP Button Functions — With Driv-
er ’s Foot OFF The Brake Pedal (In PARK Or NEUTRAL
Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has four modes, OFF, ACC, RUN and
START. To change the ignition modes without starting the
vehicle and use the accessories follow these steps:
•
Starting with the ignition in the OFF mode,
• Push the ENGINE START/STOP button once to place
the ignition to the ACC mode (instrument cluster will
display “ACC”),
• Push the ENGINE START/STOP button a second time to
place the ignition to the RUN mode (instrument cluster
will display “ON/RUN”),
• Push the ENGINE START/STOP button a third time to
return the ignition to the OFF mode (instrument cluster
will display “OFF”).
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.
266 STARTING AND OPERATING

After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
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 Procedures” in “In Case Of Emer-
gency” for further information.
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 reduce fuel con-
sumption. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or pressing the accelerator pedal
will automatically re-start the engine.
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 Display” in “Getting To
Know Your Instrument Panel” for further information.

STARTING AND OPERATING 267

•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.
• Vehicle is in 4LO transfer case mode.
• 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.

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. 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.
ENGINE BREAK-IN RECOMMENDATIONS — 3.6L &
5.7L ENGINES
For vehicles equipped with the 3.6L or 5.7L use the
following engine break-in recommendations:A long
break-in period is not required for the drivetrain (engine,
transmission, clutch, and rear axle) in your new vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
