STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
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 shift lever. Do not leave the
key fob in or near the vehicle, or in a location accessible
to children. A child could operate power windows, other
controls, or move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Turn the key fob to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key fob to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
pressed to shift out of PARK.

Tip Start Feature
Do notpress the accelerator. Turn the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.
Keyless Enter-N-Go™
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
Using The ENGINE START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pressing 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, press 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 shift lever/shift selector in PARK, then pressand release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the shift lever/shift selector is not in PARK, the ENGINE START/STOP button must be held for two
seconds and vehicle speed must be above 5 mph
(8 km/h) before the engine will shut off. The ignition
switch position will remain in the ACC position until
the shift lever/shift selector is in PARK and the button
is pressed twice to the OFF position. If the shift
lever/shift selector is not in PARK and the ENGINE
START/STOP button is pressed once, the EVIC (if
equipped) will display a “Vehicle Not In Park” mes-
sage 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.
ENGINE START/STOP Button Functions – With
Driver ’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 positions, OFF, ACC, RUN
and START. To change the ignition switch positions
without starting the vehicle and use the accessories
follow these steps.
1. Starting with the ignition switch in the OFF position:
2. Press the ENGINE START/STOP button once to change the ignition switch to the ACC position (EVIC
displays “ACC”),

To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. ASTOP/START READY message will be displayed in
the Electronic Vehicle Information Center (EVIC)
within the Stop/Start section. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understand-
ing 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 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 AUTO
STOP
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 grade5
STARTING AND OPERATING 347
Page 350 of 743

•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.To Start The Engine While In Autostop Mode
While in DRIVE the engine will start when the brake
pedal is released or the throttle pedal is depressed. The
transmission will automatically reengage upon engine
restart. During this transition the brakes will hold the
vehicle to avoid undesired vehicle movement.
Conditions that will cause the engine to start automati-
cally while in Autostop mode
The Engine Will Start Automatically When:
• The transmission selector is moved from DRIVE to
REVERSE or NEUTRAL
• To maintain cabin temperature near the HVAC settings
• HVAC is set to full defrost mode
• Autostop time exceeds 5 minutes
• Battery voltage drops too low

WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•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.
(Continued)
CAUTION! (Continued)
•Do not shift between PARK, REVERSE, NEU-
TRAL, 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.
352 STARTING AND OPERATING
Page 355 of 743
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.
(Continued)
WARNING! (Continued)
•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
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the key fob. When
the ignition is in the OFF position, the transmis-
sion is locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always remove the key
fob and lock your vehicle.
