INTRODUCTION
Dear Customer, congratulations on selecting your new
vehicle. Be assured that it represents precision workman-
ship, distinctive styling, and high quality.
This is a specialized utility vehicle. It can go places and
perform tasks that conventional passenger vehicles are not
intended. It handles and maneuvers differently from many
passenger vehicles both on-road and off-road, so take time
to become familiar with your vehicle. If equipped, the
two-wheel drive version of this vehicle was designed for
on-road use only. It is not intended for off-road driving or
use in other severe conditions suited for a four-wheel drive
vehicle. Before you start to drive this vehicle, read the
Owner ’s Manual. Be sure you are familiar with all vehicle
controls, particularly those used for braking, steering,
transmission, and transfer case shifting. Learn how your
vehicle handles on different road surfaces. Your driving
skills will improve with experience. When driving off-road,
or working the vehicle, don’t overload the vehicle or expect
the vehicle to overcome the natural laws of physics.
Always observe federal, state, provincial and local laws
wherever you drive. As with other vehicles of this type,
failure to operate this vehicle correctly may result in loss of
control or a collision. Refer to the “Driving Tips” section for
further information.This Owner ’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint you

before driving your vehicle for the first time. Following the
instructions, recommendations, tips, and important warn-
ings in this manual will help assure safe and enjoyable
operation of your vehicle.

an invalid key fob to try to start the engine. Either of these
conditions will result in the engine being shut off after two
seconds.
If the vehicle security light turns on during normal vehicle
operation (vehicle running for longer than 10 seconds), it
indicates that there is a fault in the electronics. Should this
occur, have the vehicle serviced as soon as possible by an
authorized dealer.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Customer Key Programming
Programming key fobs may be performed at an authorized
dealer.
Replacement Keys
NOTE: Only key fobs that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a key fob is programmed to a vehicle, it cannot be

• Always remove the key fobs from the vehicle and
lock all doors when leaving the vehicle unattended.
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, always remember to place the ignition in
the OFF position.
NOTE: Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of programming
a blank key fob to the vehicle electronics. A blank key fob

Automatic Doors Unlock — If Equipped
This feature unlocks all of the doors of the vehicle when
either front door is opened. This will occur only after the
vehicle has been shifted into the PARK position after the
vehicle has been driven (shifted out of PARK and all doors
closed).
Automatic Doors Unlock Programming — If
Equipped
The Automatic Doors Unlock feature can be enabled or
disabled as follows:
•For vehicles not equipped with a touchscreen radio,
refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
• For vehicles equipped with a touchscreen radio, refer to
“Uconnect Settings” in “Multimedia” for further infor-
mation.
NOTE: Use the Auto Unlock Doors feature in accordance

To provide a safer environment for children riding in the
rear seat, the rear doors (if equipped) of your vehicle have
the Child-Protection Door Lock system.
To use the system, open each rear door, use a flat blade
screwdriver (or emergency key) and rotate the dial to
engage and disengage the Child-Protection locks. When
the system on a door is engaged, that door can only be
opened by using the outside door handle even if the inside
door lock is in the unlocked position.

Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select De-
frost or Mix mode and increase the front blower speed. Do
not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions, such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
Winter months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact an authorized dealer to service your cabin
air filter, and to have it replaced when needed.

3. Speedometer•Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age 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,” turn the engine off immediately and call an
authorized dealer for service.

remains there during normal driving, the electrical
system should be serviced.
NOTE: The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold heater
system. The number of cycles and the length of the cycling
operation is controlled by the engine control module.
Post-heat operation can run for several minutes, and then
the electrical system and voltmeter needle will stabilize.
3. Oil Pressure Gauge
•The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.

•The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
6. Instrument Cluster Display
•When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
7. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
