Five-Speed Automatic TransmissionThe electronically-controlled transmission pro-
vides a precise shift schedule. The transmis-
sion 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.
Gear Ranges
NOTE:
After selecting any gear range, wait a mo-
ment to allow the selected gear to engage
before accelerating. This is especially im-
portant when the engine is cold. If there is a
need to restart the engine, be sure to turn
the ignition switch to the LOCK position
before restarting. Transmission gear en-
gagement may be delayed after restarting
the engine if the ignition switch is not turned
to the LOCK position first.
PARK
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never use PARK while the
vehicle is in motion. Apply the parking brakewhen leaving the vehicle in this range. Always
apply the parking brake first, then place the
shift lever into the PARK position.
WARNING!
•
Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
• It is dangerous to move the shift lever out of
PARK or NEUTRAL if the engine speed is
higher than idle speed. If your foot is not
firmly on 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
when your right foot is firmly on the brake
pedal.
REVERSE
This range is for moving the vehicle backward.
Use only after the vehicle has come to a
complete stop. NEUTRAL
This range is used when vehicle is standing for
prolonged periods with engine running. Engine
may be started in this range. Set the parking
brake if you must leave the vehicle.
NOTE:
Towing the vehicle, coasting, or driving for
any other reason with the shift lever in
NEUTRAL can result in severe transmission
damage. Refer to “Recreational Towing” in
“Starting and Operating” and “Towing a Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE
This range should be selected only when the
vehicle is at a complete stop and the brakes
are firmly applied. The transmission automati-
cally upshifts through fifth gear. The DRIVE
position provides optimum driving characteris-
tics under all normal operating conditions.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows you to move the shift lever left (-) or right
(+) when the shift lever is in the DRIVE position,
allowing you to limit the highest available gear.
206

The “TOW/HAUL Indicator Light” will illuminate
in the instrument cluster to indicate when the
switch has been activated. Pressing the switch
a second time restores normal operation. If the
TOW/HAUL mode is desired, the switch must
be pressed each time the engine is started.
In high ambient temperatures with sustained
high engine speed and load, an upshift, fol-
lowed shortly thereafter by a downshift, may
occur. The “TOW/HAUL Indicator Light” will
turn off. This is a normal part of the overheat
protection strategy when operating in the TOW/
HAUL mode.
Transmission Limp Home Mode
Transmission function is monitored for abnor-
mal conditions. If a condition is detected that
could result in transmission damage, the Trans-
mission Limp Home Mode will be engaged. In
this mode, the transmission will remain in the
current gear (3.6L and 3.0L Diesel engine) or in
direct gear (5.7L engine) until the vehicle is
brought to a stop.To reset the transmission, use the following
procedure:
1. Stop the vehicle.
2. Move the shift lever into the PARK position.
3. Turn the engine off, and be sure to turn the
ignition switch to the LOCK position.
4. Wait approximately 10 seconds, then restart
the engine.
5. Move the shift lever to the desired gear
range.
If the problem is no longer detected, the trans-
mission will return to normal operation. If the
problem persists, PARK, REVERSE, and NEU-
TRAL will continue to operate. Only second
gear (3.6L and 3.0L Diesel engine) or third gear
(5.7L engine) will be available in the DRIVE
position. Have the transmission checked at
your authorized dealer as soon as possible.
Torque Converter Clutch
A feature, designed to improve fuel economy,
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically, at a cali-brated speed, at light throttle. It engages at
higher speeds under heavier acceleration. This
may result in a slightly different feeling or
response during normal operation in high gear.
When the vehicle speed drops below a cali-
brated speed, or during acceleration, the
clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not en-
gage until the transmission fluid and en-
gine coolant are warm [usually after 1 to
3 miles (1.6 to 4.8 km) of driving]. Because
the engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting into Overdrive when cold. This is
normal. Manually shifting (using the ERS
shift control) between 4 (direct gear) and
5/D (Overdrive gear) positions will dem-
onstrate that the transmission is able to
shift into and out of Overdrive. For ve-
hicles with 5.7L engines (which have two
Overdrive gears), the transmission may
not shift into the top Overdrive gear (nor-
mal fifth gear) until the transmission fluid
and engine coolant are warm.
209

When additional traction is required, the 4WD
LOW position can be used to lock the front and
rear driveshafts together and force the front
and rear wheels to rotate at the same speed.
The 4WD LOW position is intended for loose,
slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may
cause increased tire wear and damage to
driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that
of the 4WD HI position at a given road speed.
Take care not to overspeed the engine and do
not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause damage
to the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in
the N (Neutral) position without first fully en-
gaging the parking brake. The transfer case N
(Neutral) position disengages both the front
and rear driveshafts from the powertrain and
will allow the vehicle to move regardless of the
transmission position. The parking brake
should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.NOTE:
Refer to “Selec-Terrain
– If Equipped” in
“Starting and Operating” for further infor-
mation on the various positions and their
intended usages.
NEUTRAL
This range disengages both the front and rear
driveshafts from the powertrain. It is to be used
for flat towing behind another vehicle. Refer to
“Recreational Towing” in “Starting and Operat-
ing” for further information.
4WD LOW
This range is for low speed four-wheel drive. It
locks the front and rear driveshafts together
and forces the front and rear wheels to rotate at
the same speed. It provides additional traction
and maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:
Refer to “Selec-Terrain – If Equipped” for
further information on the various positions
and their intended usages.
211

Shifting Procedures
4WD HI to 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster
will begin to flash and remain on solid when the
shift is complete.
NOTE:
If shift conditions/interlocks are not met, or
a transfer case motor temperature protec-tion condition exists, a “For 4x4 Low Slow
Below 3 MPH or 5 KPH Put Trans in N Press
4 Low” message will flash from the Elec-
tronic Vehicle Information Center (EVIC). Re-
fer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.
4WD LOW to 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster
will flash and go out when the shift is complete.
NOTE:
•
If shift conditions/interlocks are not met,
or a transfer case motor temperature pro-
tection condition exists, a “For 4x4 High
Slow Below 3 MPH or 5 KPH Put Trans in
N Press 4 Low” message will flash from
the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Infor- mation Center (EVIC)” in “Understanding
Your Instrument Panel” for further infor-
mation.
• Shifting into or out of 4WD LOW is pos-
sible with the vehicle completely stopped;
however, difficulty may occur due to the
mating clutch teeth not being properly
aligned. Several attempts may be re-
quired for clutch teeth alignment and shift
completion to occur. The preferred
method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is
moving faster than 3 mph (5 km/h), the
transfer case will not allow the shift.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position,
engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with
a pen, etc.) for four seconds until the LED light
by the switch starts to blink indicating shift in
progress. The light will stop blinking (stay on
solid) when the NEUTRAL shift is complete. A

sink into deeper water. Determine exit point(s)
that are downstream of your entry point to allow
for drifting.
Standing Water
Avoid driving in standing water deeper than
20 in (51 cm), and reduce speed appropriately
to minimize wave effects. Maximum speed in
20 in (51 cm) of water is less than 5 mph
(8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil, trans-
mission oil, axle, transfer case) to assure the
fluids have not been contaminated. Contami-
nated fluid (milky, foamy in appearance) should
be flushed/changed as soon as possible to
prevent component damage.
Driving in Snow, Mud and SandIn heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Oper-
ating” for further information. Do not shift to a
lower gear than necessary to maintain forwardmotion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery
roads, because engine braking may cause
skidding and loss of control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine
the conditions at the crest and/or on the
other side.
Before climbing a steep hill,
shift the trans-
mission to a lower gear and shift the transfer
case to 4WD LOW. Use first gear and 4WD
LOW for very steep hills.
If you stall or begin to lose forward motion
while climbing a steep hill, allow your vehicle to
come to a stop and immediately apply the
brakes. Restart the engine, and shift into RE-
VERSE. Back slowly down the hill, allowing the
compression braking of the engine to help
regulate your speed. If the brakes are required
to control vehicle speed, apply them lightly and
avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion,
or cannot make it to the top of a steep hill or
grade, never attempt to turn around. To do so
may result in tipping and rolling the vehicle.
Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in
NEUTRAL using only the brake.
Remember, never drive diagonally across a
hill always drive straight up or down.
If the wheels start to slip as you approach the
crest of a hill, ease off the accelerator and
maintain forward motion by turning the front
wheels slowly. This may provide a fresh “bite”
into the surface and will usually provide traction
to complete the climb.
Traction DownhillShift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the
vehicle go slowly down the hill with all four
wheels turning against engine compression
drag. This will permit you to control the vehicle
speed and direction. 219

High Range (Four-Wheel Drive Models)
On
This is the normal operating mode for ESC in
4WD HIGH range. Whenever the vehicle is
started or the transfer case (if equipped) is
shifted from 4WD LOW range or NEUTRAL
back to 4WD HIGH range, the ESC system will
be in this “On” mode. This mode should be
used for most driving situations. ESC should
only be turned to “Partial Off” mode for specific
reasons as noted below.
Partial Off
This mode is entered by momentarily pressing
the “ESC OFF” switch. When in “Partial Off”
mode, the TCS portion of ESC, except for the
BLD feature described in the TCS section, has
been disabled and the “ESC Off Indicator
Light” will be illuminated. All other stability
features of ESC function normally. This mode is
intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more
wheel spin than ESC would normally allow is
required to gain traction. To turn ESC on again,
momentarily press the “ESC OFF” switch. This
will restore the normal “ESC On” mode of
operation.NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or starting off in deep
snow, sand, or gravel, it may be desirable to
switch to the “Partial Off” mode by pressing
the “ESC OFF” switch. Once the situation
requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by
momentarily pressing the “ESC OFF”
switch. This may be done while the vehicle
is in motion.4WD Low Range
Partial Off
This is the normal operating mode for ESC in
4WD LOW range. Whenever the vehicle is
started in 4WD LOW range, or the transfer case
(if equipped) is shifted from 4WD HIGH range
or NEUTRAL to 4WD LOW range, the ESC
system will be in the “Partial Off” mode.
Trailer Sway Control (TSC)TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and
apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will
become active automatically once an exces-
sively swaying trailer is recognized. No driver
action is required. Note that TSC cannot stop all
trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Tow-
ing” in “Starting and Operating” for further
information. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and
you may feel the brakes being applied toESC OFF Switch
226

individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC
system is in the “Partial Off” mode.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.
Hill Start Assist (HSA)The HSA system is designed to assist the driver
when starting a vehicle from a stop on a hill.
HSA will maintain the level of brake pressure
the driver applied for a short period of time after
the driver takes their foot off of the brake pedal.
If the driver does not apply the throttle during
this short period of time, the system will release
brake pressure and the vehicle will roll down
the hill. The system will release brake pressure
in proportion to the amount of throttle applied
as the vehicle starts to move in the intended
direction of travel.HSA Activation Criteria
The following criteria must be met in order for
HSA to activate:
•
Vehicle must be stopped.
• Vehicle must be on a 6% (approximate)
grade or greater hill.
• Gear selection matches vehicle uphill direc-
tion (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE
gear).
HSA will work in REVERSE and all forward
gears when the activation criteria have been
met. The system will not activate if the vehicle is
placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills (i.e.,
less than 8%), with a loaded vehicle, or while
pulling a trailer, when the system will not
activate and slight rolling may occur. This
could cause a collision with another vehicle or
object. Always remember the driver is respon-
sible for braking the vehicle. Towing with HSA
HSA will provide assistance when starting on a
grade when pulling a trailer.
WARNING!
•
If you use a trailer brake controller with your
trailer, your trailer brakes may be activated
and deactivated with the brake switch. If so,
when the brake pedal is released, there
may not be enough brake pressure to hold
the vehicle and trailer on a hill and this
could cause a collision with another vehicle
or object behind you. In order to avoid
rolling down the hill while resuming accel-
eration, manually activate the trailer brake
prior to releasing the brake pedal. Always
remember the driver is responsible for
braking the vehicle.

WARNING!(Continued)
• Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the ve-
hicle is stopped in an open area with the
engine running for more than a short pe-
riod, adjust the ventilation system to force
fresh, outside air into the vehicle.
• Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
• Keep the liftgate closed when driving your
vehicle to prevent carbon monoxide and
other poisonous exhaust gases from enter-
ing the vehicle.FUEL REQUIREMENTS — DIESEL
ENGINE
Use good quality diesel fuel from a reputable
supplier. For most year-round service, No. 2
diesel fuel, meeting ASTM specification D-975
Grade S15, will provide good performance. If
the vehicle is exposed to extreme cold (below
20° F or -7° C), or is required to operate at
colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1
diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel
filters. This vehicle must only use premium
diesel fuel that meets the requirements of
EN 590. Biodiesel blends that meet EN 590
may also be used.
CAUTION!
The manufacturer requires that you must fuel
this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and
prohibits the use of Low Sulfur Highway Die-
sel fuel (500 ppm Sulfur maximum) to avoid
damage to the emissions control system.
WARNING!
Do not use alcohol or gasoline as a fuel-
blending agent. They can be unstable under
certain conditions and hazardous or explosive
when mixed with diesel fuel.
Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the accu-
mulated water from the fuel/water separator
using the provided fuel/water separator drain. If
you buy good quality fuel and follow the cold
weather advice above, fuel conditioners should
not be required in your vehicle. If available in
your area, a high cetane “premium” diesel fuel
may offer improved cold-starting and warm-up
performance.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located behind the locking fuel
filler door, on the driver’s side of the vehicle. If
the gas cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
1. Press the fuel filler door release switch (lo-
cated under the headlamp switch).
242

Check the trailer tires for proper tire inflationpressures before trailer usage.
Check for signs of tire wear or visible tire damage before towing a trailer. Refer to
“Tires – General Information” in “Starting and
Operating” for proper inspection procedure.
When replacing tires, refer to “Tires – Gen- eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying
capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
Do notinterconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury.
An electronically-actuated trailer brake con- troller is required when towing a trailer with
electronically-actuated brakes. When towing
a trailer equipped with a hydraulic surge-
actuated brake system, an electronic brake
controller is not required. Trailer brakes are recommended for trailers
over 1,000 lbs (454 kg), and required for
trailers in excess of 1,654 lbs (750 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs
(454 kg) loaded, it should have its own brakes
and they should be of adequate capacity.
Failure to do this could lead to accelerated
brake lining wear, higher brake pedal effort,
and longer stopping distances.
WARNING!
• Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system and cause it to fail. You
might not have brakes when you need
them and could have an accident.
• Towing any trailer will increase your stop-
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an accident. Towing Requirements – Trailer Lights and
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stop lights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package includes a 13 pin
wiring harness. Use a factory approved trailer
harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.
