2011 JEEP WRANGLER engine

INTRODUCTION
Congratulations on selecting your new Chrysler Group
LLC vehicle. Be assured that it represents precision
workmanship, distinctive styling, and high quality - all
essentials that are traditional to our vehicles.
This is a specialized utility vehicle. It can go places and
perform tasks that conventional passenger cars are not
intended. It handles and maneuvers differently from
many passenger cars both on-road and off-road, so take
time to become familiar with your vehicle.
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, transmis-
sion, and transfer case shifting. Learn how your vehiclehandles 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 “On-Road/Off-Road Driving Tips” in
“Starting And Operating” for further information.
This Owner’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint
you with the operation and maintenance of your vehicle.
It is supplemented by Warranty Information, and various
customer-oriented documents. Please take the time to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

WARNING!
Leaving unattended children in a vehicle is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal, or the shift lever. Do
not leave the key in the ignition. A child could
operate power windows, other controls, or move the
vehicle.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition
sounds a signal to remind you to remove the key.
NOTE:
The Key-In-Ignition reminder only sounds when
the ignition key is placed in the LOCK or ACC position.
SENTRY KEY
The Sentry Key Immobilizer System prevents unauthor-
ized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15

NOTE:A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key 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 sec-
onds), 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 compat-
ible with some after-market remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
•The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
•Obstructions between the vehicle and RKE transmitter
may reduce this range.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•Hazard switch off
•Brake switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level
•RKE PANIC button not pressed
•System not disabled from previous remote start event
•Vehicle theft alarm not active

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Car-
bon Monoxide is poisonous and can cause serious
injury or death when inhaled.
•Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
Remote Start Abort Message On Electronic Vehicle
Information Center (EVIC) — If Equipped
The following messages will display in the EVIC if the
vehicle fails to remote start or exits remote start prema-
turely:
•Remote Start Aborted - Door Ajar
•Remote Start Aborted - Hood Ajar
•Remote Start Aborted - Fuel Low
The EVIC message stays active until the ignition is turned
to the ON/RUN position.
To Enter Remote Start
Press and release the REMOTE START button
on the RKE transmitter twice within five sec-
onds. The parking lights will flash and the horn
will chirp twice (if programmed). Then, the
engine will start and the vehicle will remain in the
Remote Start mode for a 15-minute cycle.
NOTE:
•The park lamps will turn on and remain on during
Remote Start mode.
•For security, power window operation is disabled
when the vehicle is in the Remote Start mode.
•The engine can be started two consecutive times (two
15-minute cycles) with the RKE transmitter. However,

the ignition switch must be cycled to the ON/RUN
position before you can repeat the start sequence for a
third cycle.
Remote start will also cancel if any of the following occur:
•The engine stalls or RPM exceeds 2500
•Any engine warning lamps come on
•The hood is opened
•The hazard switch is pressed
•The transmission is moved out of PARK
•The brake pedal is pressed
To Exit Remote Start Mode Without Driving The
Vehicle
Press and release the REMOTE START button one time,
or allow the engine to run for the entire 15-minute cycle.
NOTE: To avoid unintentional shut downs, the system
will disable the one time press of the REMOTE START
button for two seconds after receiving a valid Remote
Start request.
To Exit Remote Start Mode And Drive The Vehicle
Before the end of the 15-minute cycle, press and release
the UNLOCK button on the RKE transmitter to unlock
the doors and disarm the Vehicle Security Alarm (if
equipped). Then, insert the key into the ignition switch
and turn the switch to the ON/RUN position.
