ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door, on the left side of
the vehicle. If the gas cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
After removing the gas cap, place the gas cap tether cable
over a hook on the inside of the fuel door. This keeps the
gas cap suspended away from and protects the vehicle’s
surface.
CAUTION!
•Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler cap. A poorly fitting cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the “Mal-
function Indicator Light (MIL)” to turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.

hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further infor-
mation.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of
the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The trailer sway control can be a mechanical telescoping
link that can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable friction
associated with the telescoping motion to dampen any
unwanted trailer swaying motions while traveling.
If equipped, the electronic Trailer Sway Control (TSC)
recognizes a swaying trailer and automatically applies
individual wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some other
connecting point of the vehicle. These kinds of hitches are the

WARNING!(Continued)
cause a loss of control, poor performance, or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure, or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross
the chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. Always, block or chockthe trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
CAUTION!
• Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Manual Transmission — If Equipped
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. However,
if frequent shifting or changes in engine speed occur while
in this range, use the AutoStick shift control (if equipped)
to select a lower gear ratio.
NOTE:
•Using a lower gear ratio while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
• If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified for police, taxi, fleet,
or frequent trailer towing. Refer to the Maintenance
Plan for the proper maintenance intervals.

AutoStick — If Equipped
When using the AutoStick shift control, select the highest
gear that allows for adequate performance and avoids
frequent downshifts. For example, choose4if the desired
speed can be maintained. Choose 3or2 if needed to
maintain the desired speed.
To prevent excess heat generation, avoid continuous driv-
ing at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear or vehicle speed when grade and road conditions
allow.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
When stopped for short periods, shift the transmission into
NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

STARTING AND OPERATING 231

When To Use Low (L Off-Road) With The 4WD Lock
Lever Engaged — If Equipped
When driving off-road, shift into low (L Off-Road [if
equipped] ) and activate the 4WD LOCK. This will provide
additional traction and activates the numerous off-road
features to improve handling and control on slippery or
difficult terrain. Due to the sustained lower gearing, low (L
Off-Road [if equipped] ) with 4WD LOCK engaged will
allow the engine to operate in a higher power range. This
will allow you to cross over obstacles and descend hills,
with improved control and less effort.
NOTE:For maximum off-road performance, premium
fuel is recommended. While the vehicle will operate on
regular fuel when in L Off-Road mode (if equipped), the
engine has been calibrated for maximum performance
using premium fuel.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore, you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum. Snow
In heavy snow or for additional control and traction at
slower speeds, activate the 4WD LOCK and shift the
transaxle to low (L Off-Road [if equipped] ) if necessary. Do
not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels and
traction will be lost. If you start to slow to a stop, try
turning your steering wheel no more than a 1/4 turn
quickly back and forth, while still applying throttle. This
will allow the tires to get a fresh
biteand help maintain
your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPM’s or vehicle speeds because engine brak-
ing may cause skidding and loss of control.
Mud
Deep mud creates a great deal of suction around the tires
and is very difficult to get through. You should use low (L
Off-Road [if equipped] ) with the 4WD LOCK engaged and
maintain your momentum. If you start to slow to a stop, try
turning your steering wheel no more than a 1/4 turn
quickly back and forth for additional traction. Mud holes

low (L Off-Road [if equipped]) with the 4WD LOCK
engaged and proceed with caution maintaining your mo-
mentum as you climb the hill.
Driving Up Hill
Once you have determined your ability to proceed and
have shifted into the appropriate gear, line your vehicle up
for the straightest possible run. Accelerate with an easy
constant throttle and apply more power as you start up the
hill. Do not race forward into a steep grade; the abrupt
change of grade could cause you to lose control. If the front
end begins to bounce, ease off the throttle slightly to bring
all four tires back on the ground. As you approach the crest
of the hill, ease off the throttle and slowly proceed over the
top. If the wheels start to slip as you approach the crest of
a hill, ease off the accelerator and maintain headway by
turning the steering wheel no more than a 1/4 turn quickly
back and forth. This will provide a freshbiteinto the
surface and will usually provide enough traction to com-
plete the climb. If you do not make it to the top, place the
vehicle in REVERSE and back straight down the grade
using engine resistance along with the vehicle brakes.WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases
the risk of a rollover, which may result in severe injury.
Driving Down Hill
Before driving down a steep hill you need to determine if
it is too steep for a safe descent. What is the surface
traction? Is the grade too steep to maintain a slow con-
trolled descent? Are there obstacles? Is it a straight descent?
Is there plenty of distance at the base of the hill to regain
control if the vehicle descends to fast? If you feel confident
in your ability to proceed then make sure you are in low (L
Off-Road [if equipped] ) with the 4WD LOCK engaged and
proceed with caution. Allow engine and hill descent brak-
ing to control the descent and apply your brakes if neces-
sary, but do not allow the tires to lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.
236 STARTING AND OPERATING

Driving Across An Incline
If at all possible avoid driving across an incline. If it is
necessary, know your vehicle’s abilities. Driving across an
incline places more weight on the down-hill wheels, which
increases the possibilities of a down-hill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible transverse the incline at an angle
heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll-
over, which may result in severe injury.
If You Stall Or Begin To Lose Headway
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift to REVERSE.
Back slowly down the hill allowing engine and hill descent
braking to control the descent and apply your brakes if
necessary, but do not allow the tires to lock.
WARNING!
If the engine stalls or you lose headway 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, which may result in severe injury.
Always back carefully straight down a hill in RE-
VERSE gear. Never back down a hill in NEUTRAL
using only the vehicle brakes. Never drive diagonally
across a hill, always drive straight up or down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible, and only be
attempted when necessary in a safe responsible manner.
You should only drive through areas which are designated
and approved. You should tread lightly and avoid damage
to the environment. You should know your vehicles abili-
ties and be able to recover it if something goes wrong. You
should never stop or shut a vehicle off when crossing deep
water unless you ingested water into the engine air intake.
If the engine stalls, do not attempt to restart it. Determine
if it has ingested water first. The key to any crossing is low
and slow. You want to use low (L Off-Road [if equipped] )
with the 4WD LOCK engaged and proceed very slowly
6
STARTING AND OPERATING 237

with a constant slow speed (3-5 mph [5–8 km/h] maxi-
mum) and light throttle. Keep the vehicle moving; do not
try to accelerate through the crossing. After crossing any
water higher than the bottom of the axle differentials, you
should inspect all of the vehicle fluids for signs of water
ingestion.
CAUTION!
Water ingestion into the transaxle, transfer case, engine
or vehicle interior can occur if you drive too fast or
through too deep of water. Water can cause permanent
damage to engine, driveline or other vehicle compo-
nents and your brakes will be less effective once wet
and/or muddy.
Before You Cross Any Type Of Water
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick.
You need to be sure of its depth, approach angle, current
and bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure you will not
be intruding on any wildlife, and you can recover the vehicle if necessary. The key to a safe crossing is the water
depth, current and bottom conditions. On soft bottoms, the
vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to
entering. This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
CAUTION!
Muddy waters can reduce the cooling system effective-
ness by depositing debris onto the radiator.
