2006 JEEP WRANGLER service indicator

keys that have been programmed to the vehicle can be
used to start and operate the vehicle for longer than the
2 second validation time period.
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 or
unlocked. During normal operation, the SKIM indicator
light will come on for 3 seconds immediately after the
ignition switch is turned on for a bulb check. Afterwards,
if the bulb remains on, this indicates a malfunction in the
electronics. If the bulb begins to flash immediately after
the ignition switch is turned on, this indicates that an
invalid key is being used to start the vehicle. Both of
these conditions will result in the engine being shut
down after 2 seconds of running. Keep in mind that a key
which has not been programmed is also considered an
invalid key even if it is cut to fit the ignition for that
vehicle. If the SKIM indicator light comes on during normal
vehicle operation (it 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.
NOTE:
•The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Mobil Speedpass™, additional Sentry Keys, or any
other transponder equipped components on the same
keychain will not cause a key-related (Transponder)
fault unless the additional part is
physically held
against the ignition key being used when starting the
vehicle. Also, cell phones, pagers, or other RF electron-
ics will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.

•On hardtop models, keep the tailgate window closed
when driving your vehicle. On fabric top models, do
not drive with the rear window curtain up unless the
side curtains are also open. This will prevent carbon
monoxide and other poisonous exhaust gases from
entering the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a indicator check when the ignition switch is
first turned on. If the indicator is not lit during starting,
have it serviced. If the light stays on or comes on while
driving, have the system checked by an authorized
dealer.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should feel the air
directed against the windshield.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

13. Oil Pressure Gauge Indicates engine oil pressure. This gauge does not
indicate oil level, and pressure varies with engine
speed, temperature and oil viscosity. Consistent lower
readings indicate possible malfunction. Seek authorized
service.
14. Coolant Temperature Gauge Indicates engine coolant temperature. The red
zone to the far right indicates possible overheat-
ing. Seek authorized service immediately if the
gauge operates in the red zone. In U.S. vehicles, tempera-
ture is indicated in degrees fahrenheit; in Canadian
vehicles in degrees centigrade.
15. Airbag Warning Light This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If
the light does not come on for 6 to 8 seconds, stays on or comes on while driving, have the airbag
system checked by an authorized dealer.
16. Check Gauges Warning Light
This light monitors the engine coolant tem-
perature, engine oil pressure, and voltage
gauges. If it detects an extreme condition a
chime will sound and the light will come on. If the light
comes on, check the operation of these gauges for a
malfunction condition.
17. Malfunction Indicator Light This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine, and
automatic transmission control systems. The light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the key from OFF to ON, have the condition
checked promptly.

Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the “Malfunction Indicator
Light” may flash to alert serious conditions 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. (See page 268 for more
information.)
18. Trip Odometer Button
Press and release this button to toggle between the
odometer and trip odometer displays. This button is also
used to reset the trip odometer to 0. While the display is
showing the trip odometer, press and hold the button for
approximately 2 seconds and the display will reset to 0. 19. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
The odometer will “illuminate” when the driver’s door
has been opened, and will remain on for 20 seconds after
exiting the vehicle.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so the correct mileage can be
determined.
The trip odometer shows individual mileage up to 999.9
miles (1 600 km). To switch from odometer to trip
odometer, press the trip odometer button.

Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident result-
ing in serious injury or death.
Keep unmounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.
226 STARTING AND OPERATING

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.” 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 dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.

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 Lamp)
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 may notbe 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.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off the
