The engine block heater cord is routed through the grille
by the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not
in use for the winter months. During winter months,
remove the heater cord wiring assembly from itself on
the c-clip.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
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 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.

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.
• 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 shift an
automatic transmission into PARK, or a manual
transmission into FIRST gear or REVERSE, turn
the engine OFF, apply the parking brake, and
remove the ignition key. When the ignition is in the
(Continued)
WARNING! (Continued)
LOCK/OFF (key removal) position, an automatic
transmission is locked in PARK, securing the ve-
hicle against unwanted movement.
• When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle. If
equipped with Keyless Enter-N-Go, always make
sure the keyless ignition node is in “OFF” mode,
remove the Key Fob from the vehicle and lock the
vehicle.
• 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
transmission gear selector out of PARK with the

brake pedal released. Make sure the transmission
is in PARK before leaving the 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. Children should be
warned not to 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.
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 ignition switch can be turned to the LOCK/
OFF (key removal) position. The Key Fob can only be
removed from the ignition when the ignition is in the
LOCK/OFF position, and the transmission is locked in
PARK whenever the ignition switch is in the LOCK/OFF
position.
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 gear
selector in PARK unless the brakes are applied. To shift
5

the transmission out of PARK, the ignition switch must
be turned to the ON/RUN position (engine running, for
vehicles with eight-speed transmission) 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.
Eight-Speed Automatic Transmission — If
Equipped
The transmission is controlled using a rotary electronic
gear selector located on the instrument panel. The trans-
mission gear range (PRND) is displayed both above the
gear selector and in the Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID). To
select a gear range, simply rotate the gear selector. You
must press the brake pedal to shift the transmission out
of PARK, or to shift from NEUTRAL into DRIVE orREVERSE, 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), simply rotate the gear
selector to the appropriate detent. Select the DRIVE range
for normal driving.
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).
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
shifting between these gears.
490 STARTING AND OPERATING
Page 493 of 919
The transmission gear selector has only PARK, RE-
VERSE, NEUTRAL, and DRIVE positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (refer toElectronic Range Select (ERS)
Operation in this section for further information). Press-
ing the GEAR-/GEAR+ switches (on the steering wheel)
while in the DRIVE position will select the highest
available transmission gear, and will display that gear
limit in the instrument cluster as 1, 2, 3, etc. Models with
the Driver Information Display (DID) will display both
the selected gear limit, and the actual current gear, while
in ERS mode.
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. Make sure the transmission is
in PARK before leaving the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL

CAUTION!
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
• Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
The following indicator should be used to ensure that
you have engaged the transmission into PARK:
• With brake pedal released, look at the transmission
gear position display and verify that it indicates the
PARK position (P). REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking
brake and shift the transmission into PARK if you must
leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
