fuel JEEP WRANGLER UNLIMITED 2015 Owners Manual

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.
• 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
• 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
Push 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.

WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant Restraint Controller
System serviced as well.
NOTE:
• Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, 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 Sys-
tem perform the following functions:
•
Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition is placed in the “OFF” position.
• Turn on the interior lights, which remain on as long as
the battery has power or until the ignition is placed in
the “OFF” position.
• Unlock the doors automatically.
System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition must be changed
from ignition START or ON/RUN to ignition OFF.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts. •
After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.

WARNING!(Continued)
•Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the
right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnor-
mal wear patterns and reduced tread life, resulting in the
need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
498 STARTING AND OPERATING

CAUTION!
•Damage to the fuel system or emission control
system could result from using an improper fuel
filler cap. A poorly fitting cap could let impurities
into the fuel system. Also, a poorly fitting aftermar-
ket cap can cause the “Malfunction Indicator Light
(MIL)” to illuminate, due to fuel vapors escaping
from the system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

WARNING!(Continued)
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the fuel filler cap about 1/4 turn until you hear
one click. This is an indication that the cap is properly
tightened. •
If the fuel filler cap is not tightened properly, the MIL
will come on. Be sure the cap is tightened every time
the vehicle is refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the “gASCAP” message will display in the
odometer display. Tighten the gas cap until a clicking
sound is heard. This is an indication that the gas cap is
properly tightened. Press the odometer reset button to
turn the message off. If the problem persists, the message
will appear the next time the vehicle is started. This
might indicate a damaged cap. If the problem is detected
twice in a row, the system will turn on the MIL. Resolving
the problem will turn the MIL off.

4. Connect the opposite end of the negative(-)jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
