2008 DODGE CHALLENGER fuel

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!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emissions control system.
•An out-of-tune engine or certain fuel or ignition mal-
functions 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 malfunc-
tioning and may require immediate service. Contact
your authorized dealer for service assistance.
•The use of fuel additives, which are now being sold as
octane enhancers, is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.

ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located behind the fuel filler door on the
left side of the vehicle. Use a finger to pull open the door.
If the gas cap is lost or damaged, be sure the replacement
cap is for use with this vehicle.NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas 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. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.

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 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 is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC). If this occurs, tighten
the fuel filler cap properly and press the TRIP ODOM-
ETER button to turn off the message. If the problem
continues, the message will appear the next time the
vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL. Refer to “Onboard Diagnostic
System” in Section 7.

NOTE:
•If a pressure of at least 19 psi (1.3 bar) cannot be
maintained in the tire, the tire is too badly damaged.
Do not attempt to drive the vehicle further. Call for
assistance.
•Do not operate the electric air pump for more than
eight minutes to avoid overheating. The air pump may
be used again once it has cooled down.
•Replace the TIREFIT sealant bottle 5 once every four
years to assure optimum operation of the system.
•If TIREFIT is liquid, clean water and a damp cloth will
remove the material from the vehicle or tire and wheel
components. Once TIREFIT sealing material has dried,
it can easily be peeled off and properly discarded.
•Do not exceed 55 mph (90 km/h) until the tire has
been inspected.
JUMP STARTING
WARNING!
•Take care to avoid the radiator cooling fan whenever the hood is raised.
It can start anytime the ignition switch is ON. You can be hurt by the fan.
•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 another vehicle. This type of start can be dangerous if done
improperly, so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow battery fluid to
contact eyes, skin, or clothing. Don’t lean over battery when attaching
clamps or allow the clamps to touch each other. If acid splashes in eyes
or on skin, flush contaminated area immediately with large quantities
of water.
•A battery generates hydrogen gas, which is flammable and explosive.
Keep flame or spark away from the vent holes.
•Do not use a booster battery or any other booster source with an output
that exceeds 12 Volts.
•The battery in this vehicle has a vent hose that should not be disconnected
and should only be replaced with a battery of the same type (vented).

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
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions 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 emissions control system. It
could also affect fuel economy and driveability. 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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, 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.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of this vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if the vehicle was recently serviced, recently had a dead battery, or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, the vehicle may fail the test.
This vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if this vehicle’s OBD II system is ready, you must
do the following:
1. Insert the ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn the ignition key to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.
