2008 JEEP PATRIOT fuel cap

WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel when the engine is running. This is
in violation of most state and Federal fire regula-
tions and will cause the Malfunction Indicator
Light (MIL) to turn on.
NOTE:Tighten the gas cap about 1/4 turn until you
hear one click. This is an indication that cap is properly
tightened.
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 refueled.
WARNING!
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.
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 Section 4 of this manual. 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
316 STARTING AND OPERATING

the vehicle is started. Refer to “Onboard Diagnostic
System — OBD II” in Section 7 of this manual for more
information.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler cap (gas cap). A poorly fitting cap could let
impurities into the fuel system.

passengers, cargo and trailer tongue weight. The total
load must be limited so that you do not exceed the
GVWR.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transaxle control systems. When these systems are oper-
ating properly, your vehicle will provide excellent per-
formance and fuel economy, as well as engine emissions
well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
•If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose or
improperly installed. A “gASCAP” message will be dis-
played in the instrument cluster. Tighten the gas cap until
aclickingsound is heard. This is an indication that the
gas cap is properly tightened. Press the trip odometer

Change Engine Oil
Refer to the “Maintenance Schedule” in Section 8 for
recommended engine oil change intervals.
Engine Oil Selection (Gasoline Engines)
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of DaimlerChrysler
Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also states the recommended engine oil viscosity
grade for your engine.
