15 seconds, then repeat the “Normal Starting”
procedure.
COLD WEATHER OPERATION
(BELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
STARTING THE ENGINE — DIESEL ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and fasten
your seat belts.The starter should not be operated for more than
25-second intervals. Waiting a few minutes
between such intervals will protect the starter from
overheating.
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 auto
-
matic transmission 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 Ú page 320.

STARTING FLUIDS
The engine is equipped with an automatic electric
air preheating system. If the instructions in this
manual are followed, the engine should start in all
conditions.
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the engine is
operating.
All message center lights are off.
Malfunction Indicator Light (MIL) is off.
Engine oil pressure is above 10 psi (69 kPa) at
idle.
Voltmeter operation:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling
operation is caused by the post-heat cycle of the
intake manifold heater system. The number of
cycles and the length of the cycling operation is
controlled by the engine control module. Post-heat
operation can run for several minutes, and then
the electrical system and voltmeter needle will
stabilize.
The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a
noticeable reduction in blower motor speed.
WARNING!
Starting fluids or flammable liquids must never
be used in the Cummins® diesel engine (see
Warning label). Never pour diesel fuel,
flammable liquid, starting fluids (ether) into the
air cleaner canister, air intake piping, or
turbocharger inlet in an attempt to start the
vehicle. This could result in a flash fire and
explosion causing serious personal injury and
engine damage.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up
may cause serious injury or death.
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 chil -
dren 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 chil -

120STARTING AND OPERATING
DIESEL EXHAUST BRAKE
(ENGINE BRAKING)
The purpose of the exhaust brake (engine braking)
feature is to supply negative (braking) torque from
the engine. Typically, the engine braking is used
for, but not limited to, vehicle towing applications
where vehicle braking can be achieved by the
internal engine power, thereby sparing the
mechanical brakes of the vehicle.
Benefits of the exhaust brake are:
Vehicle driving control.
Reduced brake fade.
Longer brake life.
Faster cab warm-up.
The exhaust brake feature will only function when
the driver toggles it on by pushing the exhaust
brake button until the Exhaust Brake Indicator is
illuminated. Normal (Full Strength) exhaust brake
mode is indicated by a yellow Exhaust Brake
Indicator.
Exhaust Brake Switch

Once the Exhaust Brake Indicator is illuminated
and the vehicle is moving faster than 5 mph
(8 km/h); the exhaust brake will automatically
operate when the driver removes pressure from
the accelerator pedal. Exhaust braking is most
effective when the engine RPM is higher. The
automatic transmission will downshift more
aggressively in TOW/HAUL mode when the exhaust
brake is enabled to increase brake performance.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving unat -
tended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave a vehicle equipped with Keyless
Enter ‘n Go™ in the ACC or ON/RUN position.
A child could operate power windows, other
controls, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle or it may roll and cause
damage or injury. Also, be certain to leave the
transmission in PARK. Failure to do so may
cause the vehicle to roll and cause damage or
injury.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
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.

STARTING AND OPERATING121
(Continued)
(Continued)
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
Automatic “Smart” Exhaust Brake technology
delivers smoother, less aggressive exhaust
braking characteristics during downhill descents.
Although it can apply full exhaust braking force if
needed, Automatic “Smart” Exhaust Brake may
not apply obvious braking if the vehicle speed is
not increasing. Automatic “Smart” Exhaust Brake
is intended to maintain vehicle speed, while Full
Exhaust Brake is intended to reduce vehicle speed.
Automatic “Smart” Exhaust Brake can be enabled
by pushing the exhaust brake button (on the center
stack) 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
“Smart” Exhaust Brake is enabled. Pushing the
exhaust brake button again will toggle the exhaust
brake mode to off.AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
CAUTION!
Use of aftermarket exhaust brakes is not recom
-
mended and could lead to engine damage.
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.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
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 come to a complete stop, then 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 posi -
tion) the transmission is locked in PARK,
securing the vehicle against unwanted move -
ment.
When leaving the vehicle, always make sure
the ignition is in the OFF position, 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 exiting the vehicle to
guard against vehicle movement 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 gear selector out of PARK with the
brake pedal released. Make sure the trans -
mission is in PARK before exiting the vehicle.
WARNING!

122STARTING AND OPERATING
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK before the ignition can be turned to the OFF
position. This helps the driver avoid inadvertently
leaving the vehicle without placing the
transmission in PARK. This system also locks the
transmission in PARK whenever the ignition is in
the OFF position.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC position (even though the
engine will be off). Ensure that the transmission is
in PARK, and the ignition is OFF (not in ACC
position) before exiting the vehicle.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI system that
holds the transmission gear selector in PARK
unless the brakes are applied. For vehicles with
8-speed transmission, to shift the transmission out
of PARK, the engine must be running and the brake
pedal must be pressed. 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. For vehicles with 6-speed
transmission, to shift the transmission out of
PARK, the ignition must be in the ON/RUN position (engine running or not) and the brake pedal must
be pressed.
The BTSI will timeout if brake pedal is pressed for
three minutes or longer continuously while in park.
It can be reset by releasing the brake for more then
three seconds, then reapplying the brake pedal or
cycling the ignition.
8-SPEED AUTOMATIC TRANSMISSION —
I
F EQUIPPED
The transmission is controlled using a rotary
electronic gear selector located on the instrument
panel. The transmission 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
NEUTRAL, when the vehicle is stopped or moving at
low speeds). 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.
NOTE:In the event of a mismatch between the gear
selector position and the actual transmission gear
(for example, driver selects PARK while driving),
the position indicator will blink continuously until
the selector is returned to the proper position, or
the requested shift can be completed.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren 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 transmis -
sion 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 (in a vehicle equipped
with Keyless Enter ‘n Go™) in the ACC or ON/
RUN position. A child could operate power
windows, other controls, or move the vehicle.
CAUTION!
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.
WARNING!

22_DPF_OM_EN_USC_t.book Page 122

STARTING AND OPERATING123
(Continued)
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions. 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. Pushing 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
Ú
page 125. Some models will display both the
selected gear limit, and the actual current gear,
while in ERS mode.
Electronic Transmission Gear Selector

Gear Ranges
Do not press the accelerator pedal 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 acceler
-
ating. 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 exiting the vehicle in this range. When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, 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.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the engine off.
Remove the key fob.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement 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
exiting the vehicle.
