RECOMMENDED DISTRIBUTION HITCH

ADJUSTMENT

1. Verify that the vehicle is at the normal ride

height.

NOTE:

The vehicle must remain in the engine run position

with all doors closed while attaching a trailer for

proper leveling of the air suspension system.
2. Position the vehicle to be ready to connect to

the trailer (do not connect the trailer).

3. For vehicles equipped with Quadra-Lift air

suspension, using the touchscreen radio

settings, enable tire jack mode. Tire jack mode

will be canceled and procedure must be

restarted if the vehicle is driven at speeds

above 5mph (8 km/h).

4. Measure the height from the top of the front

wheel opening on the fender to the ground;

this is height H1.

Measuring Height (H)

5. Attach the trailer to the vehicle without the

weight distribution bars connected.

6. Measure the height from the top of the front

wheel opening on the fender to the ground;

this is height H2.

7. Install and adjust the tension in the weight

distributing bars per the manufacturers’

recommendations so that the height of the

front fender is approximately (H2-H1)/2+H1

(about 1/2 the difference between H2 and H1

above normal ride height [H1]).

8. Use the touchscreen radio settings and switch

off tire jack mode. Make sure the truck returns

to normal ride height. Perform a visual

inspection of the trailer and weight distributing

hitch to confirm the manufacturers’

recommendations have been met.

Your vehicle may be equipped with a trailer hitch

receiver cover, this must be removed to access the

trailer hitch receiver (if equipped). This hitch

receiver cover is located at the bottom center of

the rear fascia.
1. Turn the two locking retainers located at the

bottom of the hitch receiver cover a quarter

turn counterclockwise.

NOTE:

Use a suitable tool such as a coin in the slot of the

locking retainer if needed for added leverage.

To reinstall the hitch receiver cover after towing

repeat the procedure in reverse order.

NOTE:

Be sure to engage all tabs of the hitch receiver

cover in the bumper fascia prior to installation.

RAILER

ONGUE

EIGHT

Never exceed the maximum tongue weight

stamped on your bumper or trailer hitch.

Weight Distribution

1 — Hitch Receiver Cover
2 — Locking Retainers

CAUTION!

Always load a trailer with 60% of the weight in

the front of the trailer. This places 10% of the

GTW on the tow hitch of your vehicle. Loads

balanced over the wheels or heavier in the rear

can cause the trailer to sway severely side to

side which will cause loss of control of the

vehicle and trailer. Failure to load trailers heavier

in front is the cause of many trailer collisions.

142

STARTING AND OPERATING

(Continued)

Consider the following items when computing the

weight on the rear axle of the vehicle:



The tongue weight of the trailer.



The weight of any other type of cargo or equip

ment put in or on your vehicle.



The weight of the driver and all passengers.

NOTE:

Remember that everything put into or on the trailer

adds to the load on your vehicle. Also, additional

factory-installed options or dealer-installed options

must be considered as part of the total load on

your vehicle. Refer to the Tire And Loading Infor

mation placard for the maximum combined weight

of occupants and cargo for your vehicle

page 296.

OWING

EQUIREMENTS

To promote proper break-in of your new vehicle

drivetrain components, the following guidelines

are recommended.

Perform the maintenance listed in Scheduled

Servicing

page 257. When towing a trailer,

never exceed the Gross Axle Weight Rating or

Gross Combined Weight Rating.

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.

WARNING!



Make certain that the load is secured in the

trailer and will not shift during travel. When

trailering cargo that is not fully secured,

dynamic load shifts can occur that may be

difficult for the driver to control. You could lose

control of your vehicle and have a collision.



When hauling cargo or towing a trailer, do not

overload your vehicle or trailer. Overloading

can cause a loss of control, poor performance

or damage to brakes, axle, engine, transmis

sion, steering, suspension, chassis structure

or tires.

CAUTION!



Safety chains must always be used between

your vehicle and trailer. Always connect the

chains to the 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. For four-wheel drive

vehicles, make sure the transfer case is not in

NEUTRAL. Always, block or "chock" the 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:



GVWR



GTW



GAWR



Tongue weight rating for the trailer hitch

utilized.

Towing Requirements — Tires



Do not attempt to tow a trailer while using a

compact spare tire.



Do not drive more than 50 mph (80 km/h) when

towing while using a full size spare tire.



Proper tire inflation pressures are essential to

the safe and satisfactory operation of your

vehicle.



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.



Replacing tires with a higher load carrying

capacity will not increase the vehicle's GVWR

and GAWR limits.



For further information

page 291.

Towing Requirements — Trailer Brakes



Do not interconnect the hydraulic brake system

or vacuum system of your vehicle with that of

the trailer. This could cause inadequate braking

and possible personal injury.



An electronically actuated trailer brake

controller 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 lb (453 kg) and required for trailers

in excess of 2,000 lb (907 kg).

WARNING!



Do not connect trailer brakes to your vehicle'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 stopping

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.

CAUTION!

If the trailer weighs more than 1,000 lb (453 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.

144

STARTING AND OPERATING

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 may include a four- and

seven-pin wiring harness. Use a factory approved

trailer harness and connector.

NOTE:

Do not cut or splice wiring into the vehicle’s wiring

harness.
The electrical connections are all complete to the

vehicle but you must mate the harness to a trailer

connector. Refer to the following illustrations.

NOTE:



Disconnect trailer wiring connector from the

vehicle before launching a boat (or any other

device plugged into vehicle’s electrical connect)

into water.

OWING

IPS

Before towing, practice turning, stopping, and

backing up the trailer in an area located away from

heavy traffic.

Automatic Transmission

Select the DRIVE (D) range when towing. The

transmission controls include a drive strategy to

avoid frequent shifting when towing. However, if

frequent shifting does occur while in DRIVE, select

TOW mode (if equipped), or use the AutoStick shift

control to manually select a lower gear.

NOTE:

Using TOW mode (if equipped), or selecting a lower

gear (using the AutoStick shift control) while oper

ating the vehicle under heavy loading conditions,

will improve performance and extend transmission

life by reducing excessive shifting and heat

buildup. This action will also provide better

engine braking.

AutoStick



When using the AutoStick shift control, select

the highest gear that allows for adequate perfor

mance and avoids frequent downshifts. For

example, choose “5” if the desired speed can be

maintained. Choose “4” or “3” if needed to

maintain the desired speed.



To prevent excess heat generation, avoid

continuous driving 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.

Cruise Control — If Equipped



Do not use on hilly terrain or with heavy loads.



When using the Cruise Control, if you experience

speed drops greater than 10 mph (16 km/h),

disengage until you can get back to cruising

speed.



Use Cruise Control in flat terrain and with light

loads to maximize fuel efficiency.

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

pushing the N (NEUTRAL) button or are no

longer met during the shift, then the N

(NEUTRAL) indicator light will flash continu

ously until all requirements are met or until

the N (NEUTRAL) button is released.



The ignition 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

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 N (NEUTRAL) position indicator

light indicates that shift requirements have

not been met.



If the vehicle is equipped with Quadra-Lift

air suspension, the engine should be

started and left running for a minimum 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 compensate for

temperature effects.

5. Using a ballpoint pen or similar object, push

and hold the recessed transfer case N

(NEUTRAL) button (located by the selector

switch) for four seconds. The light behind the

DRIVING TIPS

-R

OAD

RIVING

IPS

Utility vehicles have higher ground clearance and a

narrower track to make them capable of

performing in a wide variety of off-road

applications. Specific design characteristics give

them a higher center of gravity than conventional

passenger cars.
An advantage of the higher ground clearance is a

better view of the road, allowing you to anticipate

problems. They are not designed for cornering at

the same speeds as conventional passenger cars

any more than low-slung sports cars are designed

to perform satisfactorily in off-road conditions.

Avoid sharp turns or abrupt maneuvers. As with

other vehicles of this type, failure to operate this

vehicle correctly may result in loss of control or

vehicle rollover.

STARTING AND OPERATING

Quadra-Lift — If Equipped

When off-roading, it is recommended that the

lowest useable vehicle height that will clear the

current obstacle or terrain be selected. The vehicle

height should then be raised as required by the

changes in terrain.
The Selec-Terrain system will automatically change

the vehicle to the optimized height based on the

Selec-Terrain switch position. The vehicle height

can be changed from the default height for each

Selec-Terrain mode by normal use of the air

suspension switches

page 101.

When To Use 4WD LOW Range —

If Equipped

When off-road driving, shift to 4WD LOW for

additional traction. This range should be limited to

extreme situations such as deep snow, mud, or

sand where additional low speed pulling power is

needed. Vehicle speeds in excess of 25 mph

(40 km/h) should be avoided when in 4WD LOW

range.

Driving Through Water

Although your vehicle is capable of driving through

water, there are a number of precautions that

must be considered before entering the water.

NOTE:

Your vehicle is capable of water fording in up to

20 inches (51 cm) of water, while crossing small

rivers or streams. To maintain optimal perfor

mance of your vehicle's heating and ventilation

system it is recommended to switch the system

into recirculation mode during water fording.

Driving through water more than a few inches/

centimeters deep will require extra caution to

ensure safety and prevent damage to your vehicle.

If you must drive through water, try to determine

the depth and the bottom condition (and location

of any obstacles) prior to entering. Proceed with

caution and maintain a steady controlled speed

less than 5 mph (8 km/h) in deep water to

minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm

run-off), avoid crossing until the water level

recedes and/or the flow rate is reduced. If you

must cross flowing water avoid depths in excess of

9 inches (23 cm). The flowing water can erode the

streambed, causing your vehicle to 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 inches (51 cm), and reduce speed

appropriately to minimize wave effects. Maximum

speed is 5 mph (8 km/h).

WARNING!

Do not drive in 4WD LOW on dry pavement;

driveline damage may result. 4WD-LOW locks

front and rear drivelines together and does not

allow for differential action between the front to

rear driveshafts. Driving in 4WD LOW on

pavement will cause driveline binding; use only

on wet or slippery surfaces.

CAUTION!

When driving through water, do not exceed

5 mph (8 km/h). Always check water depth

before entering as a precaution, and check all

fluids afterward. Driving through water may

cause damage that may not be covered by the

New Vehicle Limited Warranty.

STARTING AND OPERATING

153

Maintenance
After driving through deep water, inspect your

vehicle fluids and lubricants (engine oil,

transmission oil, axle, transfer case) to ensure the

fluids have not been contaminated. Contaminated

fluid (milky, foamy in appearance) should be

flushed/changed as soon as possible to prevent

component damage.

Driving In Snow, Mud And Sand

In 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

page 101. Only

shift into a lower gear to maintain forward motion.

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 transmission

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 REVERSE (R). 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.

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 Downhill

When descending mountains or hills, use Hill

Descent Control or Selec-Speed Control to avoid

repeated heavy braking.
If not equipped with Hill Descent Control or

Selec-Speed Control use the following procedure:
Shift 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.
When descending mountains or hills, repeated

braking can cause brake fade with loss of braking

control. Avoid repeated heavy braking by

downshifting the transmission whenever possible.

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.
