STARTING PROCEDURES
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

WARNING! (Continued)
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 operate power windows, other con-
trols, 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.
Automatic Transmission
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
456 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
• Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Keyless Enter-N-Go — Ignition
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the Remote
Start/Keyless Enter-N-Go Key Fob is
in the passenger compartment.
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.

STARTING AND OPERATING 457

3. The system takes over and attempts to start thevehicle. 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.
To Turn Off The Engine Using ENGINE
START/STOP Button
1. Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
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 switch position will remain in the ACC
position until the gear selector is in PARK and the
button is pushed twice to the OFF position. If the gear
selector is not in PARK and the ENGINE START/
STOP button is pushed once, the Driver Information
Display (DID) 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 switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.
458 STARTING AND OPERATING

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 DID 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 accept-
able 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 AUTO-
STOP.
462 STARTING AND OPERATING

•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 condi-
tions 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
applications).
• STOP/START OFF switch is pressed.
• A STOP/START system error occurs.
• 4WD system is put into 4LO mode.

STARTING AND OPERATING 463

If the “SERVICE STOP/START SYSTEM” message ap-
pears in the DID, 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.
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 engine is idling normally and your foot is
firmly pressing the brake pedal.
