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 display 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.
4. If the gear selector is in NEUTRAL, push and release the ENGINE START/STOP button with the vehicle speed
below 5 mph (8 km/h) before the engine will shut off.
The ignition will remain in the ACC position. NOTE:
If the ignition 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.
ENGINE START/STOP Button Functions — With

Keyless Enter-N-Go Starting Procedure — Engine
Manifold Air Temperature 0° F To 66° F (–18° C to
19° C)
NOTE:The temperature displayed in the instrument clus-
ter does not necessarily reflect the engine manifold air
temperature. Refer to “Instrument Cluster Display” in
“Understanding Your Instrument Panel” for further infor-
mation. When engine temperatures fall below 66°F (19°C)
the “Wait To Start Light” will remain on indicating the
intake manifold heater system is active.
Follow the steps in the “Normal Starting” procedure
except:
1. Pushing the engine start button with the driver ’s foot on the brake will move the ignition from OFF or ACC to
RUN, and will illuminate the Wait To Starttelltale. The
engine will not immediately crank, this is normal op-
eration.
2. The “Wait To Start telltale will remain on for a period of
time that varies depending on the engine temperature. 3. While the
Wait to Start telltale is on, the instrument
cluster will additionally display a gauge or bar whose
initial length represents the full Wait to Starttime
period. Its length will decrease until it disappears when
the Wait to Start time has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for further
information.
4. After the engine “Wait To Start” telltale goes off, the engine will automatically crank.
CAUTION!
The engine may automatically crank when the “Wait
To Start” time has elapsed. To abort the automatic
starting process, ensure the driver ’s foot is fully re-
moved from the brake pedal prior to pushing the
START/STOP button to cycle the ignition off.

be noticeable at speeds below 20 mph (32 kmh). This
operating mode may last for up to an hour of idle time, or
around 20 minutes of driving time.
Your truck may have been ordered with an optional
voltage monitoring idle up feature. If a load is placed on
the electrical system while the truck is in park, this feature
will attempt to maintain normal system voltage by auto-
matically increasing engine idle speed. You may notice
several consecutive increases in idle speed, up to a maxi-
mum of 1450 RPM, as the system will attempt to utilize the
smallest increase in idle speed necessary to maintain
normal system voltage. The idle speed will return to
normal when either the electrical load is removed, or when
the brake pedal is applied.
NOTE:For instrument cluster display messages related to
the vehicle’s exhaust system, refer to “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.
Idle-Up Feature — Automatic Transmission Only
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional cab
heat, however, excessive idling may still cause the exhaust
aftertreatment system to not properly regenerate. Extended
periods of idle time should be avoided. The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehicle’s
interior.
1. With the transmission in PARK, the parking brake
applied, and the engine running, push the speed control
switch to the ON position, then push the SET switch.
2. The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the ACCEL/RESUME switch and
the idle speed will increase to approximately 1500 RPM.
To decrease the RPM, push and hold the DECEL switch
and the idle speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL switch, push the ON/OFF switch, or press the brake
pedal.
Stopping The Engine
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially important
for turbocharged, charge air-cooled engines.
134 STARTING AND OPERATING

NOTE:
•During engine shut down on vehicles equipped with
manual transmissions, it is normal for the diesel engine
to resonate heavily for a moment during engine shut off.
When the engine is connected to a manual transmission,
this resonance causes load gear rattle from the transmis-
sion. This is commonly referred to as “shut down rattle.”
The manufacturer recommends performing engine shut
down with the clutch pedal pushed to the floor (clutch
disengaged). When engine shut down is performed in
this manner the rattle is reduced (not eliminated).
• Refer to the following chart for proper engine shutdown.

Idle Shutdown
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.

Programmable Maximum Vehicle Speed (Chassis
Cab Only)
This feature allows the owner to set a maximum vehicle
speed for the vehicle. The 3500 Series maximum vehicle
speed can be set between 40 mph (64 km/h) and 87 mph
(140 km/h). The 4500/5500 Series maximum vehicle speed
can be set between 40 mph (64 km/h) and 85 mph
(136 km/h). See your local authorized dealer to enable this
feature.
NOTE:DO NOT set the maximum vehicle speed to a value
greater than what the vehicle tires are rated for.
Operating Precautions
Avoid Overheating The Engine
The temperature of the engine coolant (antifreeze) (a
mixture of 50% ethylene-glycol and 50% water) must not
exceed the normal range of the temperature gauge 240°F
(116°C) with a 21 psi (145 kPa) coolant pressure cap.
Usually the engine coolant (antifreeze) temperature indi-
cated during operation will be to the left of center in the
normal range of the gauge.
Avoid Low Coolant Temperature Operation
Continual operation at low engine coolant (antifreeze)
temperature below the normal range on the gauge 140°F
(60°C) can be harmful to the engine. Low engine coolant
(antifreeze) temperature can cause incomplete combustion
which allows carbon and varnish to form on piston rings
and injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the lubricating oil and causing rapid
wear to the engine.
Cooling System Tips — Automatic Transmission
To reduce potential for engine and transmission overheat-
ing in high ambient temperature conditions, take the
following actions:
• City Driving —
When stopped, shift the transmission into NEUTRAL and
increase engine idle speed.
• Highway Driving —
Reduce your speed.
• Up Steep Hills —
Select a lower transmission gear.
• Air Conditioning —
Turn it off temporarily.
136 STARTING AND OPERATING

pressure from the accelerator pedal. Exhaust braking is
most effective when the engine RPM is higher. The auto-
matic transmission will downshift more aggressively in
TOW/HAUL mode when the exhaust brake is enabled to
increase brake performance.
CAUTION!
Use of aftermarket exhaust brakes is not recommended
and could lead to engine damage
WARNING!
Do not use the exhaust brake feature when driving in
icy or slippery conditions as the increased engine
braking can cause the rear wheels to slide and the
vehicle to swing around with the possible loss of
vehicle control, which may cause an accident possibly
resulting in personal injury or death.
NOTE: For optimum braking power it is recommended to
use the exhaust brake while in TOW/HAUL mode. The exhaust brake feature can also be used to reduce the
engine warm up time. To use the exhaust brake as a
warm-up device, the vehicle must be stopped or moving
less than 5 mph (8 km/h), the
Exhaust Brake Indicator
must be on, and the coolant temperature must be below
180°F (82°C) and ambient temperature below 60°F (16°C).
Automatic Smart Exhaust Brake (Auto)
Automatic Exhaust Brake technology delivers smoother,
less aggressive exhaust braking characteristics during
downhill descents. Although it can apply full exhaust
braking force if needed, Automatic Exhaust Brake may not
apply obvious braking if the vehicle speed is not increas-
ing. Automatic Exhaust Brake is intended to maintain
vehicle speed, while Full Exhaust Brake is intended to
reduce vehicle speed.
Automatic Exhaust Brake can be enabled by pushing the
exhaust brake button again anytime after the normal Full
Exhaust Brake has been turned on. The “Exhaust Brake
Indicator” in the instrument cluster display will change
from Yellow to Green when Automatic Exhaust Brake is
enabled. Pushing the exhaust brake button again will
toggle the exhaust brake mode to off.

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 (in 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.
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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Interlock
which requires the transmission to be in PARK before the ignition 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 is in the LOCK/OFF position.
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 the
transmission out of PARK, the ignition must be turned to
the ON/RUN mode (engine running or not) and the brake
pedal must be pressed.
Six-Speed Automatic Transmission — If Equipped
Chassis Cab models (with automatic transmission) use the
AS69RC transmission (which is equipped with a Power
Take-Off [PTO] access cover on the side of the transmission
case). Pickup models may use either the AS69RC transmis-
sion, or the 68RFE transmission (which has no PTO access
cover).
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The gear selector is mounted on the right side of the
steering column. You must press the brake pedal to move
5
STARTING AND OPERATING 141

the gear selector out of PARK (refer to “Brake/
Transmission Shift Interlock System” in this section). To
drive, move the gear selector from PARK or NEUTRAL to
the DRIVE position. Pull the gear selector toward you
when shifting into REVERSE or PARK, or when shifting
out of PARK.
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 shift positions. Manual downshifts
can be made using the Electronic Range Select (ERS) shift
control (refer toElectronic Range Select (ERS) Operation
in this section for further information). Pressing the ERS
(-/+) switches (on the gear selector) 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. Some models 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, otherwise the load on
the transmission locking mechanism may make it difficult
to move the gear selector out of PARK. As an added
