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

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).
