2009 JEEP LIBERTY fuel pump

of gasoline may not be indicated on the gasoline pump;
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. It is even more important to
look for gasolines without MMT in Canada, because
MMT can be used at levels higher than those allowed in
the United States. MMT is prohibited in Federal and
California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Use the following guidelines to maintain your vehi-
cle’s performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
and damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
368 STARTING AND OPERATING

WARNING! (Continued)
•Never add fuel to the vehicle when the engine is
running.
•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:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap in loose, improperly installed, or damaged, a
“gASCAP” message will display in the instrument clus-
ter. Tighten the gas cap until a “clicking” sound is heard.
This is an indication that the gas cap is properly tight-
ened. Press the trip odometer reset button to turn off the
message. 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 light off.
