catalytic converter DODGE CHALLENGER 2008 Owners Manual

23. Anti-Lock Brake Warning LightThis light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
Brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
24. Low Fuel Warning Light This light will turn on and a single chime will
sound when the fuel level drops to 1/8 tank. 25. Malfunction Indicator Light (MIL)
This light is part of an onboard diagnostic system
called OBD. The OBD system monitors engine
and automatic transmission control systems. The
MIL will turn on when the key is in the ON position
before engine start. If the MIL does not come on when
turning the key from LOCK to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
The MIL flashes to alert you to serious conditions that
could lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.

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 personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission 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 improp-
erly. Refer to Section 6 for proper jump-starting
procedures and follow them carefully.
Clearing A Flooded Engine - Using ENGINE
START/STOP Button
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather proce-
dures, it may be flooded. To clear any excess fuel, press
and hold the brake pedal with your left foot, push and
hold the accelerator pedal all the way to the floor with
your right foot, and then press and release the ENGINE
START/STOP button twice. The starter motor will en-
gage automatically, run for 10 seconds, and then disen-
gage. 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 followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.

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.
272 STARTING AND OPERATING
ProCarManuals.com

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

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emissions control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
