2012 JEEP GRAND CHEROKEE fuel type

As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may re-
sult when using replacement equipment that
is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor dam-
age. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with
a TPMS, as damage to the sensors may
result.
12. Park/Headlight ON Indicator — If
Equipped This indicator will illuminate when
the park lights or headlights are
turned on.

ignition switch positions without starting the
vehicle and use the accessories follow these
steps.
•Starting with the ignition switch in the OFF
position:
• Press the ENGINE START/STOP button once
to change the ignition switch to the ACC
position (EVIC displays “IGNITION MODE
ACCESSORY”),
• Press the ENGINE START/STOP button a
second time to change the ignition switch to
the RUN position (EVIC displays “IGNITION
MODE RUN”),
• Press the ENGINE START/STOP button a
third time to return the ignition switch to the
OFF position (EVIC displays “IGNITION
MODE OFF”).
Extreme Cold Weather
(Below 20°F or 29°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in a flash fire causing serious per-
sonal injury.
• Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle. If the vehicle has a discharged
battery, booster cables may be used to
obtain a start from a booster battery or the
battery in another vehicle. This type of start
can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emer-
gencies” for further information. Clearing a Flooded Engine
(Using ENGINE START/STOP Button)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather
procedures, it may be flooded. To
clear any excess fuel, press and hold the brake
pedal, push the accelerator pedal all the way to
the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter
motor will engage automatically, run for 10 sec-
onds, and then disengage. Once this occurs,
release the accelerator pedal and the brake
pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Clearing A Flooded Engine
(Using Fob With Integrated Key)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, it may be flooded. To
clear any excess fuel, push the accelerator
pedal all the way to the floor and hold it. Then,
turn the ignition switch to the START position
and release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the

WARNING!(Continued)
• 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 one-quarter
turn until you hear one click. This is an
indication that the cap is properly tight-
ened.
• If the gas cap is not tighten properly, the
MIL will come on. Be sure the gas cap is
tightened every time the vehicle is refu-
eled.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use
the fuel filler door emergency release.
1. Open the liftgate.
2. Push down on the inboard edge of the left
storage bin, this will pop up the outboard edge. 3. Grab popped up outboard edge with other
hand to disengage snaps.
4. Remove the storage bin.
5. Pull the release cable.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or
damaged, a loose gascap indica-
tor will display in the EVIC telltale
display area. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under- standing Your Instrument Panel” for further in-
formation. Tighten the fuel filler cap properly
and press the SELECT button to turn off the
message. If the problem continues, the mes-
sage will appear the next time the vehicle is
started.
