2014 JEEP CHEROKEE bulb

If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible. If
the light is flashing when the engine is running,
immediate service is required. You may experience
reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.
•Oil Temperature Warning Light
This telltale indicates engine oil tempera-
ture is high. If the light turns on while
driving, stop the vehicle and shut off the
engine as soon as possible.
• Air Bag Warning Light
This light will turn on for four to eight
seconds as a bulb check when the ignition
switch is first turned to the ON/RUN po-
sition. If the light is either not on during
starting, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things
To Know Before Starting Your Vehicle” for further
information.
Engine Oil Change Indicator System
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the EVIC for five 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 or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go™. To turn off the
message temporarily, press and release the OK button.

592 MAINTAINING YOUR VEHICLE

Your vehicle has a simple ignition 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. Cycle the ignition switch to the ON position, but donot crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the MIL symbol come on as part
of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station. •
The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
is ready and you can proceed to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•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.

NOTE:Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as atmospheric
conditions change to allow the condensation to change
back into a vapor. Turning the lamps on will usually
accelerate the clearing process.
Low Beam And High Beam Headlamps
Bi-Xenon High Intensity Discharge (HID)
Headlamps — If Equipped
The headlamps contain a type of high voltage discharge
light source. High voltage can remain in the circuit even
with the headlamp switch off and the key removed.
Because of this, you should not attempt to service a HID
headlamp light source yourself. If an HID headlamp light
source fails, take your vehicle to an authorized dealer for
service.

NOTE:On vehicles equipped with HID headlamps,
when the headlamps are turned on, there is a blue hue to
the lights. This diminishes and becomes more white after
approximately 10 seconds, as the system charges.
WARNING!
A transient high voltage occurs at the bulb sockets of
HID headlamps when the headlamp switch is turned
ON. It may cause serious electrical shock or electro-
cution if not serviced properly. See your authorized
dealer for service.
