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.
•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” in “What To Do In Emergen-
cies” for further information.

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.
•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.WARNING!
•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 shift lever is
locked in PARK, securing the vehicle against un-
wanted movement.

446 STARTING AND OPERATING

WARNING!(Continued)
•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.
•When leaving the vehicle, always remove the key
fob and lock your vehicle.
•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.
(Continued)
WARNING!(Continued)
•Children should be warned not to touch the park-
ing 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), and do not
leave Keyless Enter-N-Go™ in the ACC or ON/
RUN position. A child could operate power win-
dows, other controls, or move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be in PARK before
the ignition switch can be turned to the OFF position. The
key fob can only be removed from the ignition when the
ignition is in the OFF position, and the shift lever is
locked in PARK whenever the ignition switch is in the
OFF position.

STARTING AND OPERATING 447

NOTE:If a malfunction occurs, the system will trap the
key fob in the ignition switch to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key fob cannot be removed until you
obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission
shifter 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.
In 8-speed vehicles, 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.
Five-Speed Automatic Transmission
(3.6L Engine) — If Equipped
The shift lever position display (located in the instrument
cluster) indicates the transmission gear range. You must
press the brake pedal to move the shift lever out of PARK
(refer to “Brake/Transmission Shift Interlock System” in
this section). To drive, move the shift lever from PARK or
NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
448 STARTING AND OPERATING

Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
moving the shift lever between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (refer to “Electronic Range Select (ERS)
Operation” in this section). Moving the shift lever to the
left or right (-/+) while in the DRIVE position will select
the highest available transmission gear, and will display
that gear in the instrument cluster as 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.

STARTING AND OPERATING 449

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.
•If there is a need to restart the engine, be sure to cycle
the ignition to the OFF position before restarting.
Transmission gear engagement may be delayed after
restarting the engine if the key is not cycled to the OFF
position first.
PARK
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 place the shift
lever in PARK first, and then apply the parking brake.When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of 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.
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 completely 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.

could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, firmly move the shift lever
all the way forward and to the left until it stops and is
fully seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
•With brake pedal released, verify that the shift lever
will not move out of PARK.
