Replacing The Battery In The Key Fob
The recommended replacement battery is
CR2032.
NOTE:
Customers are recommended to use a
battery obtained from Mopar. Aftermarket
coin battery dimensions may not meet the
original OEM coin battery dimensions.
Perchlorate Material – special handling may
apply. See www.dtsc.ca.gov/hazard-
ouswaste/perchlorate.

1. Push the mechanical key release button and release the mechanical key to access
the battery case screw located on the side
of the key fob.

2. Rotate the screw located on the side of the key fob using a small screwdriver.

3. Take out the battery case. Remove and replace the battery observing its polarity.
4. Refit the battery case inside the key fob and turn the screw to lock it into place.
Programming And Requesting Additional Key
Fobs
Programming the key fob may be performed by
an authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be re-purposed and reprogrammed to
another vehicle. Duplication of keys may be performed at an
authorized dealer. The VIN is required for
authorized dealer replacement of keys.
NOTE:
Only keys that have been programmed to the
vehicle electronics can be used to start the
vehicle. Once a Sentry Key has been
programmed to a vehicle, it cannot be
programmed to any other vehicle. When having
the Sentry Key Immobilizer system serviced,
bring all vehicle keys with you to an authorized
dealer.
WARNING!
Always remove the key fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.
Always remember to place the ignition in
the OFF mode.2

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 Maintenance (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.
The OBD ll may not be ready if your vehicle was
recently serviced, recently had a depleted
battery or a battery replacement. If the OBD ll
system should be determined not ready for the
I/M test, your vehicle may fail the test.
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 do not 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 ready and you
should not proceed to the I/M station.
The MIL will not flash at all and will
remain fully illuminated until you place
the ignition in the off position 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 an 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.

IN CASE OF EMERGENCY
HAZARD WARNING FLASHERS
The Hazard Warning Flashers switch is located
on the instrument panel below the climate
controls.
Hazard Warning Flashers Switch
Push the switch to turn on the Hazard Warning
Flashers. When the switch is activated, all
directional turn signals will flash on and off to
warn oncoming traffic of an emergency. Push
the switch a second time to turn off the Hazard
Warning Flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled and
it is creating a safety hazard for other motorists.
When you must leave the vehicle to seek
assistance, the Hazard Warning Flashers will
continue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use, the Hazard Warning
Flashers may wear down your battery.
FUSES
General Information
WARNING!
When replacing a blown fuse, always use
an appropriate replacement fuse with the
same amp rating as the original fuse. Never
replace a fuse with another fuse of higher
amp rating. Never replace a blown fuse with
metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity
or vice versa. Failure to use proper fuses
may result in serious personal injury, fire
and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
