2013 JEEP WRANGLER UNLIMITED engine

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.
NOTE: After reviewing the owner information, it
should be stored in the vehicle for convenient referenc-
ing and remain with the vehicle when sold.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has factory-trained tech-
nicians and genuine MOPAR  parts, and cares about
your satisfaction. ROLLOVER WARNING
Utility vehicles have a significantly higher rollover rate
than other types of vehicles. This vehicle has a higher
ground clearance and a higher center of gravity than
many passenger cars. It is capable of performing better in
a wide variety of off-road applications. Driven in an
unsafe manner, all vehicles can go out of control. Because
of the higher center of gravity and the narrower track, if
this vehicle is out of control it may roll over when some
other vehicles may not.

2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

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 ve-
hicle operation. Therefore, only keys that are programmed
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. 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.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. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled. (Continued)28 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING! (Continued)• 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 pre-
maturely:
• Remote Start Aborted — Door Ajar
• Remote Start Aborted — Hood Ajar
• Remote Start Aborted — Fuel Low
• Remote Start Aborted — L/Gate Ajar
• Remote Start Aborted — System Fault 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 vehicle doors will lock, 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. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 29

• 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.
NOTE: The ignition switch must be in the ON/RUN
position in order to drive the vehicle.30 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Supplemental Seat-Mounted Side Air Bags (SAB)
Inflator Units — If Equipped
The Supplemental Seat-Mounted Side Air Bags Inflator
Units (if equipped) are designed to activate only in
certain side collisions.
The ORC determines if a side collision requires the side
air bags to inflate, based on several factors, including the
severity and type of collision.
Based on several factors, including the severity and type
of collision, the side air bag inflator on the crash side of
the vehicle is triggered releasing a quantity of non-toxic
gas. The inflating SAB exits through the seat seam into
the space between the occupant and the door. The SAB
fully inflate in about 10 milliseconds. The side air bag
moves at a very high speed and with such a high force
that it could injure you if you are not seated properly, or
if items are positioned in the area where the side air bag
inflates. This especially applies to children. Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the ORC
in determining appropriate response to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition key is turned off.70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING! (Continued)• It is dangerous to try to repair any part of the air bag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free. If any of
the following occurs, have an authorized dealer service
the air bag system immediately.
• The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to the ON/RUN position. • The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
