CAUTION!
•ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
If it’s necessary to keep the trailer hitch and hitch ball
assembly mounted for a long period, it is possible to filter
out the trailer hitch and hitch ball assembly presence in
sensor field of view. The filtering operation must be
performed only by an authorized dealer.
LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at speeds above
37 mph (60 km/h) and below 112 mph (180 km/h). The LaneSense system uses a forward looking camera to detect
lane markings and measure vehicle position within the
lane boundaries.
When both lane markings are detected and the driver
unintentionally drifts out of the lane (no turn signal
applied), the LaneSense system provides a haptic warning
in the form of torque applied to the steering wheel to
prompt the driver to remain within the lane boundaries. If
the driver continues to unintentionally drift out of the lane,
the LaneSense system provides a visual warning through
the instrument cluster display to prompt the driver to
remain within the lane boundaries.
The driver may manually override the haptic warning by
applying torque into the steering wheel at any time.
When only a single lane marking is detected and the driver
unintentionally drifts across the lane marking (no turn
signal applied), the LaneSense system provides a visual
warning through the instrument cluster display to prompt
the driver to remain within the lane. When only a single
lane marking is detected, a haptic (torque) warning will not
be provided.

NOTE:If snow, ice, mud, or any foreign substance builds
up on the camera lens, clean the lens, rinse with water, and
dry with a soft cloth. Do not cover the lens.
WARNING!
Drivers must be careful when backing up even when
using the Rear Back Up Camera. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible for
the safety of your surroundings and must continue to
pay attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
• To avoid vehicle damage, Rear Back Up Camera
should only be used as a parking aid. The Rear Back
Up Camera is unable to view every obstacle or object
in your drive path.
• To avoid vehicle damage, the vehicle must be driven
slowly when using the Rear Back Up Camera to be
able to stop in time when an obstacle is seen. It is

CAUTION! (Continued)
recommended that the driver look frequently over
his/her shoulder when using the Rear Back Up
Camera.
FOUR WHEEL DRIVE — JEEP ACTIVE DRIVE
(4WD) AND JEEP ACTIVE DRIVE LOW (4WD LOW)
Your vehicle may be equipped with a Power Transfer Unit
(PTU). This system is automatic with no driver inputs or
additional driving skills required. Under normal driving
conditions, the front wheels provide most of the traction. If
the front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.
Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a preemptive effort to improve vehicle launch
and performance characteristics.

STARTING AND OPERATING 287
•An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated 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 (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have a collision.
• Towing any trailer will increase your stopping dis-
tance. 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 a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
(Continued)
CAUTION! (Continued)
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
(If Equipped)
Whenever you pull a trailer, regardless of the trailer size,
stoplights 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 vehicles 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.
302 STARTING AND OPERATING
NOTE:
•Disconnect trailer wiring connector from the vehicle
before launching a boat (or any other device plugged
into vehicle’s electrical connect) into water.
• Be sure to reconnect after clear from water area.
Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing the trailer in an area located away from heavy
traffic.

STARTING AND OPERATING 303
Automatic Transmission — If Equipped
Select the DRIVE 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, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve performance
and extend transmission life by reducing excessive shifting
and heat build up. This action will also provide better
engine braking.
AutoStick
• When using the AutoStick shift control, select the high-
est gear that allows for adequate performance 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.
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 of time, shift the transmis-
sion into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
304 STARTING AND OPERATING
Standing Water — Trailhawk Only
Avoid driving in standing water deeper than 19 inches (48
cm), and reduce speed appropriately to minimize wave
effects. Maximum speed in 19 inches (48 cm) of water is
less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
Unit and Rear Drive Module) to assure they have not been
contaminated. Contaminated fluids and lubricants (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 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-Wheel
Drive Operation” in “Starting And Operating” for further
information. 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.
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 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
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 brakes. Restart the engine and shift
to REVERSE. 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 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. Always back straight down a hill in
REVERSE gear carefully. Never back down a hill in
NEUTRAL using only the brake.
308 STARTING AND OPERATING
If a tire is punctured, you can make a first emergency repair
using the Tire Service Kit located in the rear storage
compartment inside the storage container.
1. Remove the Tire Service Kit from the vehicle, take it outfrom the bag and place it near the punctured tire. Screw
the clear flexible filling tube to the tire valve.
2. Insert the power plug into the vehicle power outlet socket. Start the vehicle engine.
3. Push the Tire Service Kit power button to the “I” position. The electric compressor will be turned on,
sealant and air will inflate the tire.
Minimum 26 psi (1.8 bar) of pressure should be reached within
20 minutes. If the pressure has not been reached turn off and
remove the Tire Service Kit, drive the vehicle 30 feet (10 meters)
back and forth, to better distribute the sealant inside the tire.
4. Attach the clear flexible filling tube of the compressordirectly to the tire valve and repeat the inflation process.
When the correct pressure has been reached, start driving the
vehicle to uniformly distribute the sealant inside the tire.
After 10 minutes, stop and check the tire pressure. If the
pressure is below 19 psi (1.3 bar), do not drive the vehicle, as
the tire is too damaged, contact the nearest authorized dealer.
WARNING!
Tire Service Kit is not a permanent flat tire repair. Have
the tire inspected and repaired or replaced after using
Tire Service Kit. Do not exceed 65 mph (110 km/h) until
the tire is repaired or replaced. Failure to follow this
warning can result in injuries that are serious or fatal
to you, your passengers, and others around you. Have
the tire checked as soon as possible at an authorized
dealer.
If the pressure is at 19 psi (1.3 bar) or above repeat the
inflation process to reach the correct tire pressure and
continue driving.
5. Peel off the warning label from the bottle and place it on the dashboard as a reminder to the driver that the tire
has been treated with Tire Service Kit.
WARNING!
The metal end fitting from Power Plug may get hot
after use, so it should be handled carefully.

IN CASE OF EMERGENCY 359
Disconnecting The Jumper Cables
1. Disconnect the negative(-)end of the jumper cable from
the engine ground of the vehicle with the discharged
battery.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the positive (+)post of the vehicle with the
discharged battery.
If frequent jump starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if plugged
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
REFUELING IN EMERGENCY
The fuel filling procedure in case of emergency is described
in the “Emergency Refueling Procedure”. Refer to “Adding
Fuel” in “Starting And Operating” for further information.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating your engine by taking the appro-
priate action.
• On the highways — slow down.
• In city traffic — while stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads “H,” pull over
and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H” and you hear continuous chimes, turn the engine
off immediately and call for service.
