2008 JEEP COMPASS fuel pump

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge/Fuel Door Location
When the ignition switch is in the ON position,
the pointer will show the level of fuel remain-
ing in the fuel tank. The fuel pump symbol
points to the side of the vehicle where the fuel
door is located.
2. Voltage Warning Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the Charging System light remains on,
or comes on while driving, it means that the vehicle is
experiencing a problem with the charging system. Obtain
SERVICE IMMEDIATELY. See your authorized dealer.3. Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected, the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable
and not need towing, however see your dealer for service
as soon as possible.
If the light is flashing when the engine is running you
may experience power loss, an elevated/rough idle, and
increased brake pedal effort, and your vehicle may
require towing. Immediate service is required.
The light will come on when the ignition switch is first
turned on and remain on briefly as a bulb check. This is
normal. If the light does not come on during starting,
have the system checked by an authorized dealer.
160 UNDERSTANDING YOUR INSTRUMENT PANEL

MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles. The manufacturer recom-
mends using gasolines without MMT. Since the MMT
content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer whether or not
his/her 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 reformu-
lated gasolines.
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 would result in additional cost. Therefore
you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.

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 Malfunction
Indicator Light 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 ªGASCAPº
message will be displayed in the Odometer/Trip Odom-
eter in the instrument cluster. Refer to ªInstrument
Cluster Descriptionº 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
the vehicle is started. Refer to ªOnboard Diagnostic
System Ð OBDIIº 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.
