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.
ENGINE START/STOP Button Functions — With
Driver ’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 positions, OFF, ACC, RUN. To change the ignition switch positions without starting the
vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Push the ENGINE START/STOP button once to change
the ignition to the ACC position.
3. Push the ENGINE START/STOP button a second time to change the ignition to the RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF position.
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 (available
from your authorized dealer) is recommended.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the

STARTING AND OPERATING 327

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.
Gasoline Engine Only
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 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 reverse. 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.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the upper
switch bank just below the radio.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming traffic
of an emergency. Push the switch a second time to turn off
the Hazard Warning flashers.
This is an emergency warning system and it should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down. •
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
430 WHAT TO DO IN EMERGENCIES

Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to gain access
to the positive battery post. Do not jump off fuses. Only
jump directly off positive post which has a positive (+)
symbol on or around the post.
WARNING!
• Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Apply the parking brake, shift the automatic transmis- sion into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
