catalytic converter CHRYSLER PT CRUISER 2007 1.G Owners Manual

9. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position
before engine start. If the bulb does not come on when
turning the key from OFF to ON/RUN, have the condi-
tion checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalyticconverter damage. The vehicle should be serviced as
soon as possible if this occurs. (See page 360 for more
information.)
10. Turn Signal Indicators
The arrows will flash in unison with the exterior
turn signal, when using the turn signal lever.
NOTE:Turn signal bulbs are located in the Instrument
Panel. (See page 181 for more information.)
11. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light —
If Equipped
If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the ESP, or TCS — if
equipped. (See page 298 for more information.)
222 UNDERSTANDING YOUR INSTRUMENT PANEL

Manual Transaxle
Before starting the engine fully apply the parking brake,
press the clutch pedal to the floor and place the gear
selector in NEUTRAL.
NOTE:The engine will not start unless the clutch pedal
is pressed to the floor.
Normal Starting
Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator pedal.
Simply turn the ignition switch to the “START’” position
and release when the engine starts. If the engine has not
started within 3 seconds, slightly depress the accelerator
pedal while continuing to crank. If the engine fails to start
within 15 seconds, turn the ignition switch to the “OFF”
position, wait 10 to 15 seconds, then repeat the normal
starting procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle 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 improp-
erly, so follow the procedure carefully. See section 6
of this manual for jump starting instructions.
Extremely Cold Weather (below
20°F or
29°C)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.

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:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, 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
malfunctioning and may require immediate service.
Contact your dealer for service assistance.

WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle 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 improp-
erly, so follow this procedure carefully.
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.2. When boosting from a battery in another vehicle, park
that vehicle within booster cable reach but without
letting the vehicles touch. Set parking brake, place auto-
matic transaxle in PARK (manual transaxle in NEU-
TRAL) and turn ignition to OFF for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the jumper cable to the positive terminal of the dis-
charged battery.

Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to the Engine data Label located under the
hood for the proper type of spark plug for use in your
vehicle.
Ignition Wiring System
The ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Cracked,
damaged, or faulty cables should be replaced.
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 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.
