STARTING AND OPERATING 417

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!
•When leaving the vehicle, always make sure the
ignition is in the OFF position, 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 trans-
mission gear selector.
(Continued)
WARNING!(Continued)
•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
controls, or move the vehicle.
Automatic Transmission
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.

STARTING AND OPERATING 421

and START. To change the ignition positions without
starting the vehicle and use the accessories follow these
steps:
•Starting with the ignition in the OFF position,
•Push the ENGINE START/STOP button once to place
the ignition to the ACC position (DID will display
“ACC”),
•Push the ENGINE START/STOP button a second time
to place the ignition to the RUN position (DID will
display “ON/RUN”),
•Push the ENGINE START/STOP button a third time to
return the ignition to the OFF position (DID will
display “OFF”).
Extreme Cold Weather (Below –20°F Or−29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
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.
(Continued)
424 STARTING AND OPERATING

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.
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.
(Continued)
426 STARTING AND OPERATING

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
transmission is locked in PARK, securing the ve-
hicle against unwanted movement.
•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.
(Continued)
WARNING!(Continued)
•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 parking brake, brake pedal
or the transmission 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 position.
A child could operate power windows, other con-
trols, or move the vehicle.

STARTING AND OPERATING 427

CAUTION!
Damage to the transmission may occur if the follow-
ing 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, 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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placing
the transmission in PARK.
This system also locks the transmission in PARK when-
ever the ignition switch is in the OFF position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever 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
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
428 STARTING AND OPERATING

•The torque converter clutch may engage at lower
engine speeds and remain on longer.
•The overall driving performance will be more conser-
vative.
•Vehicles with Quadra-Lift™ air suspension will oper-
ate in#Aero#mode over a broader speed range. Refer
to#Quadra-Lift™#in#Starting and Operating#for
further information.
•Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation — Summit Models Only
Your vehicle is equipped with an Active Noise Cancella-
tion System. This system uses four microphones embed-
ded in the headliner to detect undesirable exhaust noise.
An onboard frequency generator creates counteracting
sound waves through the audio system to help keep the
vehicle quiet.
Eight–Speed Automatic Transmission
The electronic shift lever in this vehicle does not slide like
a conventional shifter. Instead, the shift lever is spring
loaded and moves forward and rearward, always return-
ing to the center position after each gear is selected. The
transmission gear (PRND) is displayed both on the shift
lever and in the Driver Information Display (DID). To
select a gear range, press the lock button on the shift lever
and move the lever rearward or forward. You must also
press the brake pedal to shift the transmission out of
PARK, or to shift from NEUTRAL into DRIVE or RE-
VERSE when the vehicle is stopped or moving at low
speeds (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). To shift past multiple gear ranges at
once (such as PARK to DRIVE), move the lever past the
first (or second) detent. Select the DRIVE range for
normal driving.
430 STARTING AND OPERATING

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.
NOTE:On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
•Your vehicle could move and injure you and others
if it is not in PARK. Check by trying to move the
shift lever out of PARK with the brake pedal
released. Make sure the transmission is in PARK
before leaving the vehicle.
