2007 CHRYSLER CROSSFIRE fuel

of unleaded gasoline having lower sulfur to determine if
the problem is fuel-related prior to returning your vehicle
to an authorized dealer for service.
CAUTION!
If the CHECK ENGINE Light is flashing, immediate
service is required. See the Onboard Diagnostic
System (OBDII) paragraph in the Maintaining Your
Vehicle section of this manual.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located under the fuel filler door, on the
passenger's side of the vehicle. To open the door, be sure it
is unlocked, then gently press the rear edge of the door
until a click can be heard, then release. The door rear edge
will spring open enough to grasp and pull it completely
open. If the central locking system does not release the fuel
filler door, see your authorized dealer for service. If the gas
cap is lost or damaged, be sure the replacement cap has
been designed for use with this vehicle.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper gas cap. A
poorly fitting cap could let impurities into the fuel
system. The CHECK ENGINE light will come on if
the gas cap is not properly secured.
NOTE:The fuel tank filler tube has a restricting door
about 2 inches (50 mm) down from the opening. If fuel is
poured from a portable container, the container should
have a flexible nozzle long enough to force open the
restricting door.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
STARTING AND OPERATING 189
5

With the key in the ignition switch turned to the ON/
RUN position, the fuel reserve warning light comes on. It
should go out immediately when the engine is running.
If the warning light does not go out after starting the
engine, or if it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of approxi-
mately 2 gallons (7.5 liters).
Leaving the engine running and the fuel cap open can
cause the CHECK ENGINE light to illuminate.
NOTE:
²
When the fuel nozzle ªclicksº or shuts off, the fuel
tank is full.
²Tighten the gas cap until you hear a single click. This
is an indication that the gas cap is properly tightened.
The CHECK ENGINE light will come on if the gas cap
is not properly secured. Make sure that the gas cap is
tightened each time the vehicle is refueled.
WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank is filled.
²Never add fuel to the vehicle when the engine is
running.
²A 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 outside the vehicle while filling.
190 STARTING AND OPERATING

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your Crossfire is equipped with a sophisti-
cated onboard diagnostic system called OBD II. This
system monitors the performance of the emissions and
engine control systems. When these systems are operat-
ing properly, your vehicle will provide excellent perfor-
mance 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 CHECK ENGINE Light. It will also store
diagnostic codes and other information to assist your
service technician in making repairs. Although 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 CHECK ENGINE light
on could cause further damage to the emission con-
trol system. It could also affect fuel economy and
drivability. The vehicle must be serviced before any
state emissions tests can be performed.
If the CHECK ENGINE light is flashing, severe catalytic
converter damage and power loss will soon occur. Im-
mediate service is required.
If the gas cap is not tightened properly, the CHECK
ENGINE light may come on. Be sure the gas cap is
tightened every time you add fuel. Tighten the cap until
you hear it ªclickº once.

WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
technician.
MAINTENANCE PROCEDURES
The pages that follow contain the maintenance service
recommended by the engineers who designed your ve-
hicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop.
You can check the oil level using the procedure described
in Checking Engine Oil Level in the Understanding Your
Instrument Panel section, or by checking the engine oil
dipstick.

Drive Belts - Check Condition and Tension
At the distance shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specifications
and procedures shown in the Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the distance specified in the appropriate main-
tenance chart. The entire set should be replaced if there is
any malfunction due to a faulty spark plug. Check the
specifications section for the proper type of spark plug
for use in your vehicle.
Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
each interval called out by FSS.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.
Engine Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent filter replacement may be necessary. See your
authorized dealer for service.

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly serviced to assure
proper catalyst operation and prevent possible catalyst
damage.
If the CHECK ENGINE light is flashing, immediate
service is required.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.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
230 MAINTAINING YOUR VEHICLE

Points to Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulation on the radiator and being vapor-
ized when the thermostat opens, allowing hot water to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
²Do not overfill the coolant bottle.
²Check coolant freeze point in the system.
²If frequent coolant additions are required, or if the
level in the recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
²Maintain a coolant concentration of a minimum of 50%
ethylene glycol Extended Life Coolant and high qual-
ity water with recommended antifreeze for proper
corrosion protection of your engine cooling system
that contains aluminum components.
²Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean,
also.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor fuel
economy, and increased emissions.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
