2009 JEEP PATRIOT service indicator

Airbag Warning Light
The light should come on and remain on for six to eight
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, flickers, 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. See your
authorized dealer for service if your defroster is
inoperable.
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 the wheel nuts for tightness. Check the
tires (including 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 the area under the vehicle after overnight parking
for fuel, engine coolant, oil or other fluid leaks. Also, if
gasoline fumes are detected or fuel, power steering fluid,
transmission fluid or brake fluid leaks are suspected, the
cause should be located and corrected immediately.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

13. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proachesH, this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
passH, the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in Section 6
for more information.14. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related to
the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during
each stop.
170 UNDERSTANDING YOUR INSTRUMENT PANEL

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.
15. Transmission Temperature Warning Light
During sustained high speed driving on hot
days, the automatic transaxle oil may become
too hot. If this happens, the transmission over-
heat indicator light will come on and the
vehicle will slow slightly until the automatic transaxle
cools down enough to allow a return to the requested
speed. If the high speed is maintained, the overheating
will reoccur as before in a cyclic fashion.
16. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 16 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.17. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H” and you hear continuous chimes, turn the
engine off immediately, and call an authorized deal-
ership for service.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see Section 7
of this manual. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
18. Cruise Indicator — If Equipped
This indicator shows that the Speed Control
System is ON.
19. Cruise SET Indicator — If Equipped
This indicator shows that the Speed Control System is
SET.20. Shift Lever Indicator

shift lever selection.
NOTE:You must apply the brakes before shifting from
PARK.
21. Odometer/Trip Odometer Reset Button
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 (0 km). The odometer must be in Trip mode to
reset.
22. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle

replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHAngE OIL” message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty cycle based, which
means the engine oil change interval may fluctuate
dependent upon your personal driving style. Unless
reset, this message will continue to display each time you
turn the ignition switch to the ON/RUN position. To turn
off the message temporarily, press and release the Trip
Odometer button on the instrument cluster. To reset the
oil change indicator system (after performing the sched-
uled maintenance) refer to the following procedure.1. Turn the ignition switch to the ON position.Do not
start the engine.
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
25. OFF ROAD Indicator — If Equipped
The symbol illuminates (is armed) when the 4WD lock
switch is activated and the transmission range indicator
is in LOW or REVERSE position.
26. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an Onboard Diagnostic system called OBD II that
monitors emissions, engine, and automatic trans-
mission control systems. The light will illuminate when
176 UNDERSTANDING YOUR INSTRUMENT PANEL

the key is in the ON/RUN position before engine start. If
the light does not come on when turning the key from
OFF to ON/RUN, have the condition 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 MIL flashes when the engine is running, serious
conditions may exist 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.
27. Hill Descent Indicator — If Equipped
The symbol illuminates (is armed) when the
4WD Lock switch is activated and the trans-
mission range indicator is in LOW or REVERSE
position (Off-Road Mode).28. Front Fog Light Indicator — If Equipped
This light shows when the front fog lights are on.
29. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
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 Electronic Stability
Program (ESP), or Traction Control System (TCS).
30. Electronic Stability Program (ESP) Indicator Light
The malfunction lamp for the Electronic Stabil-
ity Program (ESP) is combined with Brake
Assist System (BAS). The yellow “ESP/BAS
Warning Lamp” comes on when the ignition
switch is turned to the “ON” position. They should go
out with the engine running. If the “ESP/BAS Warning
