2011 JEEP LIBERTY service indicator

N
Neutral - This range disengages both the front driveshaft
and rear driveshaft from the powertrain. To be used for
flat towing behind another vehicle. Refer to “Recreational
Towing” in “Starting and Operating” for further
information.
Transfer Case Position Indicator Lights
The four-wheel drive indicator lights (4WD, 4 LOW) are
located in the instrument cluster. The NEUTRAL indica-
tor light is located on the transfer case switch. If there is
no indicator light on or flashing, the transfer case posi-
tion is two-wheel drive (2WD). If the indicator light is on,
the desired position (4WD AUTO, 4WD LOW, or NEU-
TRAL) has been obtained.
If One Or More Shift Requirements Are Not Met:
•An indicator light will flash.
•The transfer casewill notshift. NOTE:
The “SERV 4WD Warning Light” monitors the
electric shift four-wheel drive system. If this light re-
mains on after engine start up, or it illuminates during
driving, it means that the four-wheel drive system is not
functioning properly and that service is required.
Shifting Procedures
NOTE: If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift, the indicator light for the previous position
will remain on, and the newly selected position indicator
light will continue to flash until all the requirements for
the selected position have been met. To retry a shift, move
the transfer case switch back to the original position,
make certain all shift requirements have been met, wait
five seconds, and try the shift again.
2WD To 4WD Auto
Move the transfer case switch to the desired position.
Shifts between 2WD and 4WD Auto can be done with the

STARTING AND OPERATING 331

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.
CAUTION!
Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type and circumference
on each wheel. Any difference in tire size can cause
damage to the transfer case. Tire rotation schedule
should be followed to balance tire wear.
Life Of Tire
The service life of a tire is dependent upon various
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven

STARTING AND OPERATING 373

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
•If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer or a
“CHECK gASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
444 MAINTAINING YOUR VEHICLE

“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until aclickingsound is heard.
This is an indication that the gas cap is properly tight-
ened.
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 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 may notbe 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.

MAINTAINING YOUR VEHICLE 445

MAINTENANCE SCHEDULE
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.On Non-EVIC equipped vehicles “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).
