2014 JEEP PATRIOT fuel cap

Vehicle Odometer Messages
When the appropriate conditions exist, the following
odometer messages will display:
door............................. Door Ajar
gATE ............................. Gate Ajar
gASCAP ...................... Fuel Cap Fault
LoW tirE ....................LowTirePr essure
CHANgE OIL ..............Oil Change Required
NOTE: If the vehicle is equipped with the optional
Electronic Vehicle Information Center (EVIC) in the in-
strument cluster, warnings such as “Door Ajar”, and
“Gate Ajar” will be displayed in the EVIC display. For
additional information, refer to “Electronic Vehicle Infor-
mation Center — If Equipped”. gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer display
area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
LoW tirE
When tire pressure is low, the odometer display will
toggle between LoW and tirE for three cycles.
CHANgE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer display for approxi-
mately 12 seconds after a single chime has sounded to
indicate the next scheduled oil change interval. The
224 UNDERSTANDING YOUR INSTRUMENT PANEL

engine oil change indicator system is duty cycle based,
which means the engine oil change interval may fluctuate
dependent upon your personal driving style. Unless
reset, this message will continue to display each time you
turn the ignition switch to the ON/RUN position. To turn
off the message temporarily, press and release the Trip
Odometer button on the instrument cluster. To reset the
oil change indicator system (after performing the sched-
uled maintenance), refer to the following procedure:
1. Turn the ignition switch to the ON/RUN position.Do
not start the engine.
2. Fully depress the accelerator pedal slowly three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure. 24. OFF ROAD Indicator — If Equipped
The symbol illuminates (is armed) when the 4WD lock
switch is activated and the shift lever is in LOW or
REVERSE position.
25. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an Onboard Diagnostic system called OBD II that
monitors emissions, engine, and automatic trans-
mission control systems. The light will illuminate when
the key is in the ON/RUN position before engine start. If
the light does not come on when turning the key from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several of your typical driving cycles. In most situations,
the vehicle will drive normally and will not require towing.

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
(Continued)
WARNING! (Continued)
•Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal
conditions repaired promptly. Until repaired, drive
with all side windows fully open.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door, on the left side
of the vehicle. If the gas cap is lost or damaged, be sure
the replacement cap is for use with this vehicle.

STARTING AND OPERATING 413

After removing the gas cap, place the gas cap tether cable
over a hook on the inside of the fuel door. This keeps the
gas cap suspended away from and protects the vehicle’s
surface.CAUTION!
•Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler cap (gas cap). A poorly fitting cap could
let impurities into the fuel system.
• A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
(Continued)
Fuel Filler Cap
414 STARTING AND OPERATING

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 gas cap about 1/4 turn until you hear one
click. This is an indication that cap is properly tight-
ened. •
If the gas cap is not tightened properly, the MIL will
come on. Be sure the gas cap is tightened every time
the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose or improperly installed, a “gASCAP”
message will be displayed in the Odometer/Trip Odom-
eter in the instrument cluster. Refer to “Instrument
Cluster Description” in “Understanding Your Instrument
Panel” for further information. Tighten the fuel filler cap
properly and press the odometer/trip odometer RESET
button to turn the message off. If the problem continues,
the message will appear the next time the vehicle is
started. Refer to “Onboard Diagnostic System” in “Main-
taining Your Vehicle” for further information.

STARTING AND OPERATING 415

Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier suspension compo-
nents do not necessarily increase the vehicle’s GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight. Store heavier items down low and be sure you
distribute their weight as evenly as possible. Stow all
loose items securely before driving. Improper weight
distribution can have an adverse effect on the way your
vehicle steers and handles, and the way the brakes
operate.5
