the brake while stopped on an incline, HSA will continue
to hold the brake pressure for a short period. If the driver
does not apply the throttle before this time expires, the
system will release brake pressure and the vehicle will
roll down the hill as normal.
The following conditions must be met in order for HSA to
activate:
•The feature must be enabled.
•The vehicle must be stopped.
•Park brake must be off.
•Driver door must be closed.
•The vehicle must be on a sufficient grade.
•The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).•HSA will work in REVERSE gear and all forward
gears. The system will not activate if the transmission
is in PARK or NEUTRAL. For vehicles equipped with
a manual transmission if the clutch is pressed HSA will
remain active.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or
while pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the driver ’s
responsibility to be attentive to distance to other
vehicles, people, and objects, and most importantly
brake operation to ensure safe operation of the ve-
hicle under all road conditions. Your complete atten-
tion is always required while driving to maintain

STARTING AND OPERATING 623
WARNING!(Continued)
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive
shaft from the powertrain, and will allow the vehicle
to roll, even if the automatic transmission is in PARK
(or manual transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop, with the engine
running. Firmly apply the parking brake.2. Shift the transmission to NEUTRAL.
NOTE:If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. With manual shift transfer case, shift the transfer case
lever into NEUTRAL (N).
•With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button. Some models
have a small, recessed “N” button (at the center of
the transfer case switches) that must be pushed using
a ballpoint pen or similar object. Other models have
a rectangular NEUTRAL switch, below the rotary
transfer case control knob. The NEUTRAL (N) indi-
cator light will blink while the shift is in progress.
The light will stop blinking (stay on solid) when the
718 STARTING AND OPERATING
shift to NEUTRAL (N) is complete. After the shift is
completed and the NEUTRAL (N) light stays on,
release the NEUTRAL (N) button.
6. Release the parking brake.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual
transmissions) for five seconds and ensure that there is
no vehicle movement.
9. Repeat steps 7 and 8 with automatic transmission in
DRIVE or manual transmission in first gear.
10. Shift the transmission to NEUTRAL. Firmly apply
the parking brake. Turn OFF the engine. For vehicles
with Keyless Enter-N-Go, push and hold the EN-
GINE START/STOP button until the engine shuts off.11. Shift the transmission into PARK or place manual
transmission in gear (NOT in Neutral). On 8-speed
transmissions the shifter will automatically select
PARK when the engine is turned off.
12. Turn the ignition switch to the OFF position, then
cycle the Key or the Keyless Enter-N-Go button to the
RUN position and back to the OFF position. Remove
the Key Fob from the ignition switch.
13. Attach the vehicle to the tow vehicle using a suitable
tow bar.
14. Release the parking brake.
NOTE:With electronic shift transfer case:
•Steps 2 through 4 are requirements that must be met
before pushing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met before push-
ing the NEUTRAL (N) button or are no longer met
5
STARTING AND OPERATING 719
during the shift, the NEUTRAL (N) indicator light will
flash continuously until all requirements are met or
until the NEUTRAL (N) button is released.
•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
•A flashing NEUTRAL (N) position indicator light
indicates that shift requirements have not been met.
•If the vehicle is equipped with air suspension, the
engine should be started and left running for a mini-
mum of 60 seconds (with all the doors closed) at least
once every 24 hours. This process allows the air
suspension to adjust the vehicle’s ride height to com-
pensate for temperature effects.Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine. Shift the transmission into NEU-
TRAL. Depress the clutch pedal on a manual trans-
mission.
•With manual shift transfer case, shift the transfer
case lever to the desired position.
•With electronic shift transfer case with rotary selector
switch, push and hold the transfer case NEUTRAL
(N) button until the NEUTRAL (N) indicator light
turns off. After the NEUTRAL (N) indicator light
turns off, release the NEUTRAL (N) button. After the
720 STARTING AND OPERATING
NEUTRAL (N) button has been released, the transfer
case will shift to the position indicated by the selec-
tor switch.
•With electronic shift transfer case with push-button
selector switch, push and hold the switch for the
desired transfer case position, until the NEUTRAL
(N) indicator light turns off and the desired position
indicator light turns on.
NOTE:When shifting out of transfer case NEUTRAL (N),
turning the engine OFF is not required, but may be
helpful to avoid gear clash. With the 8-speed automatic
transmission, the engine must remain running, since
turning the engine OFF will shift the transmission to
PARK (and the transmission must be in NEUTRAL for
the transfer case to shift out of NEUTRAL).5. Turn the engine OFF. Shift automatic transmission into
PARK. On 8-speed transmissions the shifter will auto-
matically select PARK when the engine is turned off.
6. Release the brake pedal (and clutch pedal on a manual
transmission).
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake
pedal (and clutch pedal on manual transmissions),
and check that the vehicle operates normally.

STARTING AND OPERATING 721
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE (with automatic transmission) or 2nd gear
and REVERSE (with manual transmission), while gently
pressing the accelerator. Use the least amount of accel-
erator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the en-
gine.
NOTE:For trucks equipped with 8-speed automatic
transmission: Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph (8 km/h) or
less. Whenever the transmission remains in NEUTRAL
for more than two seconds, you must push the brake
pedal to engage DRIVE or REVERSE.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
NOTE:Push theESC Offswitch, to place the Electronic
Stability Control (ESC) system inPartial Offmode,
before rocking the vehicle. Refer to “Electronic Brake
Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, push theESC
Offswitch again to restoreESC Onmode.
