252 STARTING AND OPERATING

STARTING THE ENGINE — GAS
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.

CAUTION!(Continued)
•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.
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.
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 will return to the OFF mode.
3. If the gear selector is not in PARK (with vehicle stopped) and the ENGINE START/STOP button is pushed once,
the transmission will automatically select PARK and the
engine will turn off, however the ignition will remain in
the ACC mode (NOT the OFF mode). Never leave a
vehicle out of the PARK position, or it could roll.
4. If the gear selector is in NEUTRAL, and the vehicle speed is below 5 mph (8 km/h), pushing the START/
STOP button once will turn the engine off. The ignition
will remain in the ACC mode.
254 STARTING AND OPERATING

5. If the vehicle speed is above 5 mph (8 km/h), theENGINE START/STOP button must be held for two
seconds (or three short pushes in a row) to turn the
engine off. The ignition will remain in the ACC mode
(NOT the OFF mode) if the engine is turned off when
the transmission is not in PARK.
NOTE: The system will automatically time out and the
ignition will cycle to the OFF mode after 30 minutes of
inactivity if the ignition is left in the ACC or RUN (engine
not running) mode and the transmission is in PARK.
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 three modes: OFF, ACC, and RUN.
To change the ignition modes without starting the vehicle
and use the accessories, follow these steps:
1. Starting with the ignition in the OFF mode,
2. Push the ENGINE START/STOP button once to place the ignition to the ACC mode (instrument cluster will
display “ACC”), 3. Push the ENGINE START/STOP button a second time
to place the ignition to the RUN mode (instrument
cluster will display “ON/RUN”),
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF mode (instrument cluster
will display “OFF”).
NOTE: Only press one pedal at a time while driving the
vehicle. Torque performance of the vehicle could be re-
duced if both pedals are pressed at the same time. If
pressure is detected on both pedals simultaneously, a
warning message will display in the instrument cluster. For
further information, refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”.
AutoPark
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK.
The conditions under which AutoPark will engage are
outlined on the following pages.
6
STARTING AND OPERATING 255

WARNING!
•Driver inattention could lead to failure to place the
vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the instrument
cluster display and on the gear selector. If the P
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not de-
signed to replace the need to shift your vehicle into
PARK. It is a back up system and should not be
relied upon as the primary method by which the
driver shifts the vehicle into PARK.
If the vehicle is not in PARK and the driver turns off the
engine, the vehicle may AutoPark.
AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with an 8-speed transmission
• Vehicle is not in PARK
• Vehicle Speed is 1.2 MPH (1.9 km/h) or less
• Ignition switched from RUN to ACC NOTE:
For Keyless Go equipped vehicles, The engine will
turn off and the ignition switch will change to ACC mode.
After 30 minutes the ignition switches to OFF automati-
cally, unless the driver turns the ignition switch OFF.
If the vehicle is not in PARK and the driver exits the
vehicle with the engine running, the vehicle may Au-
toPark.
AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with an 8-speed transmission
• Vehicle is not in PARK
• Vehicle Speed is 1.2 MPH (1.9 km/h) or less
• Driver ’s seat belt is unbuckled
• Driver ’s door is ajar

displayed in the instrument cluster. In these cases, the
shifter must be returned to “P” to select desired gear.
256 STARTING AND OPERATING

If the driver shifts into PARK while moving, the vehicle
may AutoPark.
AutoPark will engageONLYwhen vehicle speed is
1.2 MPH (1.9 km/h) or less.
The MESSAGE “ Vehicle Speed is Too High to Shift to
P”will be displayed in the instrument cluster if vehicle
speed is above 1.2 MPH (1.9 km/h).

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 Procedure” in “In Case Of Emergency” for
further information.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 25 seconds at a time.
Wait 60 seconds before trying again.
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.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
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.
