Automatic Transmission
Start the engine with the transmission in PARK position.
Apply the brake before shifting into any driving range.
NOTE:
•This vehicle is equipped with a transmission shift inter-
locking system. The brake pedal must be pressed to shift
out of PARK.
• If equipped with an 8 speed transmission starting the
vehicle in NEUTRAL is not possible unless the Manual
Park Release has been activated. For the Manual Park
Release operation refer to Manual Park Release in “What
To Do In Emergencies”.
Tip Start Feature
Do not press the accelerator. Cycle 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 — Ignition
This feature allows the driver to operate
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
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.
382 STARTING AND OPERATING
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 switch will return to the OFF position.
3. If the gear selector is not in PARK, the ENGINE START/ STOP button must be held for two seconds or three short
pushes in a row with the vehicle speed above 5 mph
(8 km/h) before the engine will shut off. The ignition
switch position will remain in the ACC position until the
gear selector is in PARK and the button is pushed twice
to the OFF position. If the gear selector is not in PARK
and the ENGINE START/STOP button is pushed once,
the instrument cluster will display a “Vehicle Not In
Park” message 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.Idle Shutdown — 6.4L Engine Only
This feature can be enabled so that the truck will automati-
cally shutdown when the truck has been idling for a set
period of time when the engine is at operating tempera-
ture. Idle time can be set in 5 minute increments between 5
and 60 minutes. See your local authorized dealer to enable
this feature.
NOTE: The idle shut down timer is disabled while the PTO
is active.5
STARTING AND OPERATING 383
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 following
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, NEUTRAL,
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 apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the key fob. When
the ignition is in the LOCK/OFF (key removal)
position, (or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the vehicle.

386 STARTING AND OPERATING
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 instrument cluster. 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 or REVERSE, when the
vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). 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 pre-
cise 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.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE positions. Manual downshifts can
be made using the Electronic Range Select (ERS) shift
control (refer to
Electronic Range Select (ERS) Operation
in this section for further information). Pressing the
GEAR-/GEAR+ switches (on the steering wheel) while in
the DRIVE position will select the highest available trans-
mission gear, and will display that gear limit in the
instrument cluster as 1, 2, 3, etc. Some models will display
both the selected gear limit, and the actual current gear,
while in ERS mode.
388 STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), select TOW/HAUL mode or use
the Electronic Range Select (ERS) shift control (refer to
Electronic Range Select (ERS) Operationin this section for
further information) to select a lower gear range. Under
these conditions, using a lower gear range will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
NOTE: In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
