2007 CHRYSLER PT CRUISER check engine light

Key-In-Ignition Reminder
Opening the driver's door when the key is in the ignition,
sounds a signal to remind you to remove the key.
NOTE:With the driver's door open, and the key in the
ignition, both the power door locks and Remote Keyless
Entry (RKE) will not function.
SENTRY KEY Ð IF EQUIPPED
The Sentry Key Immobilizer System prevents unautho-
rized operation of the vehicle by disabling the engine.
The system will shut the engine off after two (2) seconds
of running if an invalid key is used to start the vehicle.
This system utilizes ignition keys, which have an elec-
tronic chip (transponder) embedded into them. Only
keys that have been programmed to the vehicle can be
used to start and operate the vehicle.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked orunlocked. During normal operation, the Theft Alarm/
Immobilizer Light will come on for three (3) seconds
immediately after the ignition switch is turned on for a
bulb check. Afterwards, if the bulb remains on, this
indicates a problem with the electronics.
If the bulb begins to flash after the bulb check, this
indicates that an invalid key has been used to start the
vehicle. Both of these conditions will result in the engine
being shut off after two (2) seconds of running.
Keep in mind that a key, which has not been pro-
grammed is also considered an invalid key even if it is
cut to fit the ignition lock cylinder for that vehicle.
If the Theft Alarm/Immobilizer Light comes on during
normal vehicle operation, (the vehicle has been running
for longer than 10 seconds), a fault has been detected in
the electronics and the vehicle should be serviced as soon
as possible.

Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (bent retractor, torn
webbing, etc. If there is any question regarding belt or
retractor condition, replace the belt.
Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check wheel nuts for tightness, and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected or fuel, power steering fluid or brake
fluid leaks are suspected, the cause should be located and
corrected immediately.
114 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 364 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 184 for more information.)
11. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light Ð
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 Ð if
equipped. (See page 300 for more information.)

the ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
13. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on briefly when
the ignition switch is first turned ON and remain on
briefly as a bulb check. If the light stays on or comes on
while driving, it means that there is a problem with the
charging system. Obtain SERVICE IMMEDIATELY.14. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a warning chime
will sound 10 times. After the chime turns off, the
engine will still be critically hot until the light goes out.
15. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will come on for about six seconds. A chime
will sound if you have not pulled the shoulder belt
out of the retractor. This is a reminder to ªbuckle upº. If
you do not buckle up, the light will remain on.
16. Theft Alarm Light Ð If Equipped
This light will flash rapidly for several seconds when the
alarm system is arming. The light will begin to flash
slowly indicating that the system is armed. (See page 35
for more information.)

17. Low Fuel Light
When the fuel level drops to 2 gallons, the fuel
symbol will light and a single chime will sound.
18. Anti-Lock Warning Light (ABS) Ð If Equipped
This light monitors the Anti-Lock Brake System
(ABS) described elsewhere in this manual. This
light will come on when the ignition key is
turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on during driving,
it indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required, however,
the conventional brake system will continue to operate
normally provided that 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 benefit of Anti-Lock
Brakes.The warning light should be checked frequently to assure
that it is operating properly. Turn the ignition key to the
on position, but do not start the vehicle. The light should
come on. If the light does not come on, have the system
checked by an authorized dealer.
19. Front Fog Light Indicator Ð If Equipped
This light shows when the front fog lights are ON.
(See page 183 for more information.)
20. Airbag Light
The light comes on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light does not
come on during starting, stays on, or comes on
while driving, have the system checked by an authorized
dealer. (See page 102 for more information.)
21. Oil Pressure Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch is

turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on during starting, have the system checked by
an authorized dealer.
If the light comes on and remains on while driving, stop
the vehicle and shut off the engine. DO NOT OPERATE
THE VEHICLE UNTIL THE CAUSE IS CORRECTED.
The light does not show the quantity of oil in the engine.
This can be determined using the procedure shown in
Section 7. (See page 368 for more information.)
22. High Beam Indicator
This light shows that the headlights are on high
beam. Pull the turn signal lever toward the steer-
ing wheel to switch the headlights from high or low
beam.23. Electronic Vehicle Information Center DisplayÐIf

When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. (See page 231 for more information.)
24. Odometer/Trip Odometer Reset Knob
Press this button to change the display from odometer to
either of the two trip odometer settings. Trip A or Trip B
will appear when in the trip odometer mode. Push in and
hold the button for two seconds to reset the trip odometer
to 0 miles or kilometers. The odometer must be in trip
mode to reset.

a9clicking9sound is heard. This is an indication that the
gas cap is properly tightened. Press the odometer reset
button to turn the message off. If the problem persists,
the message will appear the next time the vehicle is
started. This might indicate a damaged cap. If the prob-
lem is detected twice in a row, the system will turn on the
Malfunction Indicator Light (MIL). Resolving the prob-
lem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Light)is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your 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.

At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder and transaxle and add as needed.
²Check all lights and all other electrical items for correct
operation.
²Check rubber seals on each side of the radiator for
proper fit.
At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the CV joints and front suspension compo-
nents.
