2012 JEEP PATRIOT bulb

•Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
30. 4WD! Warning Light
This light monitors the 4-Wheel Drive (4WD)
system. The light will come on, for a bulb
check, when the ignition key is turned to the
ON/RUN position and may stay on for as long
as three seconds.
When lit solid:There is an 4WD system fault. 4WD
performance will be at a reduced level. Service the 4WD
system soon.
When blinking:The 4WD system is temporarily dis-
abled due to overload condition.31. Electronic Vehicle Information Center (EVIC)
Display — If Equipped
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages.
For further information, refer to “Electronic Vehicle In-
formation Center (EVIC)”.
MINI-TRIP COMPUTER — IF EQUIPPED
The Mini-Trip Computer is located in the instrument
cluster and features a driver-interactive trip information
and temperature display.
NOTE:The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature; therefore, temperature readings
are not updated when the vehicle is not moving.

WARNING! (Continued)
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
The “ABS Warning Light” monitors the ABS
System. The light will come on when the
ignition switch is turned to the ON position
and may stay on for as long as four seconds.
If the “ABS Warning Light” remains on or comes on
while 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 if the “Brake Warning
Light” is not on.If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not come on when the ignition switch is turned to
the ON position, have the bulb repaired as soon as
possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and Electronic Brake Force
Distribution (EBD) systems are not functioning. Immedi-
ate repair to the ABS is required.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self-check cycle to ensure that the ABS
working properly. This self-check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).

persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the MIL. Resolving the problem 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 that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II 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 II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.

VEHICLE STORAGE
If you will not be using your vehicle for more than
21 days, you may want to take steps to preserve your
battery.
•Disengage the mini-fuse in the Power Distribution
Center labeled IOD (Ignition Off-Draw).
•Or disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
