Trailer towing tips
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective. Also, see the information on tow/haul mode operation
underAutomatic transmission operationin theDrivingchapter.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•Do not allow the static water level to rise above the bottom edge of
the rear bumper.
•Do not allow waves to break higher than 6 in (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•Causing internal damage to the components.
•Affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.

RECREATIONAL TOWING
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to theClimate
Controlschapter.
Follow these guidelines if you need to tow your vehicle behind another
vehicle, such as a motor home. The guidelines are designed to prevent
damage to your vehicle and its transmission after it is hooked-up to the
tow vehicle or tow dolly.
2WD vehiclescannot be towed with any wheels on the ground as
vehicle or transmission damage may occur. The vehicle must be towed
with all four wheels off the ground (i.e. with a car-hauling trailer).
4WD vehiclescan only be towed with all wheels on the ground by
placing the transfer case in its neutral position and engaging the
four-wheel-down towing feature. Perform the steps outlined in the
Four-wheel-down towingsection after positioning your vehicle behind
the tow vehicle and properly securing them together
Four-wheel-down towing
1. Turn the ignition to the on position; do not start the engine.
2. Press and hold the brake pedal.
3. Shift the 4WD switch to 2H.
4. Shift the transmission to N (Neutral).
5. Rotate the 4WD switch from 2H to 4L and back to 2H five times
within seven seconds.
•If completed successfully, the instrument cluster displaysNEUTRAL
TOW LEAVE IN NorNEUTRAL TOW ENABLED LEAVE
TRANSMISSION IN NEUTRAL, indicating that the vehicle is safe
to tow with all wheels on the ground.
•If the message is not shown in the display, the procedure must be
performed again from the beginning.
•An audible noise may be heard as the transfer case shifts into its
neutral position; this is normal.
6. Leave the transmission in N (Neutral) and turn the ignition as far as it
will go toward the off position (it will not turn fully off when the
transmission is in N [Neutral]). The key must be left in the ignition while
towing. To lock and unlock your vehicle, use the keyless entry keypad or
extra set of keys.
7. Release the brake pedal.

WARNING:Do not disconnect the battery during recreational
towing. Doing so will prevent the transfer case from shifting
properly and may cause the vehicle to roll even if the transmission is in
P (Park).
WARNING:Shifting the transfer case to its neutral position for
recreational towing may cause the vehicle to be able to roll even
if the transmission is in P (Park). The driver or others could be
injured. Make sure the foot brake is depressed and the vehicle is in a
secure and safe position while the transfer case is being shifted to its
neutral position.
WARNING:Failing to put the transfer case in its neutral
position will damage vehicle components.
Note:Four-wheel-down towing status can be checked at any time by
opening the driver’s door or turning the ignition to the accessory or on
position and verifying the NEUTRAL TOW ENABLED message is
displayed in the cluster.
To exit four-wheel-down towing and return the transfer case to its 2H
position:
1. With the vehicle still properly secured to the tow vehicle, press and
hold the brake pedal.
2. Turn the ignition to the on position; do not start the engine.
3. Shift the transmission out of N (Neutral) and into any gear.
4. Release the brake pedal.
•If completed successfully, the instrument cluster displays4X2,and
NEUTRAL TOW DISABLED.
•If the indicator light and message do not display, the procedure must
be performed again from the beginning.
•An audible noise may be heard as the transfer case shifts out of its
neutral position; this is normal.
5. Apply the parking brake, then disconnect the vehicle from the tow vehicle.
6. Release the parking brake, start the engine, and shift the transmission
to D (Drive) to make sure the transfer case is out of N (Neutral).
7. If the transfer case will not successfully shift out of N (Neutral), set
the parking brake until the vehicle can be serviced.

WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracwith RSCsystem is an indication that
at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTracwith RSCsystem
activates, SLOW DOWN.
WARNING:When a failure has been detected with the
AdvanceTracwith RSCsystem, the stability control light will
illuminate steadily. AdvanceTracwith RSCcan be disabled manually
by pressing the stability control off button located on the center of the
instrument panel. When the system is disabled, the stability control off
light will illuminate. If the stability control light still illuminates
steadily, have the system serviced by an authorized dealer immediately.
Operating your vehicle with AdvanceTracwith RSCdisabled could
lead to an increased risk of loss of vehicle control, vehicle rollover,
personal injury and death.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.
The AdvanceTracwith RSC
system includes a stability control
off button located on the center of
the instrument panel.
There are two stability control lights
in the instrument cluster. The stability control light in the instrument
cluster will flash if a driving situation causes the AdvanceTracwith
RSCsystem to operate. If the stability control light illuminates steadily,
have the system serviced by an authorized dealer immediately.
Note:If the system cannot be turned off, refer toMyKeyin theLocks
and Securitychapter for more information.

Electronic stability control (ESC)
Electronic stability control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely or
avoiding objects in the roadway. ESC operates by applying brakes to one or
more of the wheels individually and, if necessary, reducing engine power if
the system detects that the vehicle is about to skid or slide laterally.
During ESC events, the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate the ESC system, which
include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).
The Electronic Stability Control system may be deactivated in certain
situations. See theSwitching off AdvanceTracwith RSCsection
following.
Roll Stability Control™ (RSC)
Roll Stability Control™ (RSC) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSCoperates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the Roll Stability Control™ (RSC), the
stability control light in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the Roll Stability
Control™ system, which include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
The Roll Stability Control™ system may be deactivated in certain situations.

If the steering wanders or pulls equipped with either an EPS or a
hydraulic steering system, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited-slip axle functions like a standard rear axle. The axle may exhibit
a slight noise or vibration in tight turns with low vehicle speed. This is
normal behavior and indicates the axle is working.
Electronic locking differential (ELD) (if equipped)
The electronic locking differential provides added traction on slippery
and/or off-road surfaces, particularly when one wheel is on a poor
traction surface. In normal driving conditions, the rear axle functions as
a standard axle. The ELD may be locked or unlocked by the vehicle
operator. Refer toFour-wheel drive (4WD) operationsection in this
chapter for further details on ELD function and usage. When the axle is
unlocked, it will function like a standard rear axle. When the axle is
locked, it will not allow the rear wheels to rotate at different speeds
when turning. The ELD axle is not recommended for use on good
traction surfaces such as dry pavement. Doing so may result in abnormal
driving behavior while cornering and excessive tire wear.
PREPARING TO DRIVE
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground clearance,
giving the vehicle a higher center of gravity than a passenger car.

4. Drive off in the normal manner. The brakes will be released automatically.
If your vehicle gets stuck in mud or snow
Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note:Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING:To help avoid personal injury, always use caution
when in reverse and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.

The RSS detects obstacles up to
6 feet (2 meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
While receiving a warning the radio
volume may be reduced to a
predetermined level. After the
warning goes away, the radio will return to the previous volume.
The RSS may have reduced performance or an increased chance of false
detection if the tailgate is not locked and in the upright position. If the
tailgate is down, the RSS tone may be heard intermittently or
continuously. The tone may also be heard if items in the truck bed
protrude rearward outside the bed.
The RSS automatically turns on when the gearshift lever is placed in R
(Reverse) and the ignition is on. A control in the message center allows
the driver to disable the system, refer toMessage center and Rear park
aidin theInstrument Clusterchapter for more information.
Note:If the system cannot be turned off, refer toMyKeyrestricted
featuresin theLocks and Securitychapter for more information.
Note:If your vehicle is equipped with a fully integrated electronic trailer
brake controller (TBC) and a trailer with electric trailer brakes is
connected to your vehicle, the RSS will be disabled. When the vehicle is
shifted into reverse, the message center display will remain in the Rear
Park Aid Off selection. For more information on the TBC, refer to the
Tires, Wheels and Loadingchapter.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
