20GETTING TO KNOW YOUR VEHICLE
In case the ignition switch does not change with
the push of a button, the key fob may have a low or
fully depleted battery. A low key fob battery can be
verified by referring to the instrument cluster
display, which will display directions to follow.
NOTE:A low key fob battery condition may be indicated by
a message in the instrument cluster display, or by
the LED light on the key fob. If the LED key fob light
no longer illuminates from key fob button pushes,
then the key fob battery requires replacement
Ú page 480.
To Lock/Unlock The Doors And Tailgate
Push and release the unlock button on the key fob
once to unlock the driver’s door, or, twice within
five seconds to unlock all doors, the tailgate and
the RamBox (if equipped). To lock all the doors and
the tailgate, push the lock button once.
When the doors are unlocked, the turn signals will
flash and the illuminated entry system will be
activated. When the doors are locked, the turn
signals will flash and the horn will chirp.
All doors can be programmed to unlock on the first
push of the unlock button. The horn chirp when the
lock button is pushed can be programmed on/off
within Uconnect Settings Ú page 234.
Key Left Vehicle Feature
If a valid key fob is no longer detected inside the
vehicle while the vehicle’s ignition system is in the
ON/RUN or START position, the message “Key Left
Vehicle” will be shown in the instrument cluster
display along with an interior chime. An exterior
audible and visual alert will also be activated to
warn the driver.
The vehicle’s horn will rapidly chirp three times
along with a single flash of the vehicle’s exterior
lights.
NOTE:
The doors have to be open and then closed in
order for the vehicle to check for the presence of
a key fob; the Key Left Vehicle feature will not
activate until all of the doors are closed.
These alerts will not be activated in situations
where the vehicle’s engine is left running with
the key fob inside.
Air Suspension (Remote Lowering Of The
Vehicle) — If Equipped
For easy entry and loading, your vehicle
can be lowered by pushing the key fob air
suspension lowering button two times.
When air suspension lowering is
requested using the key fob, the vehicle will send a
series of chirps and flashes to alert the customer
that the operation has begun and will continue
these alerts until it successfully lowers. The following conditions must be met for the
vehicle to lower remotely:
The vehicle must not already be in Entry/Exit
ride height.
The vehicle battery must be fully charged.
All doors must be closed.
The key fob must be out of the vehicle.
Gear selector must be in PARK.
NOTE:Ensure the vehicle is clear of all objects, pets, and
people prior to remote lowering.
Canceling Remote Lowering
Vehicle lowering can be canceled at anytime.
When vehicle lowering is canceled, the vehicle will
raise to the next defined level and lock out the
remote lowering feature for five seconds until a
new request is made.
To cancel vehicle lowering, push the key fob air
suspension lowering button one time during the
lowering process. When vehicle lowering is
canceled, the horn will chirp two times and the turn
signal lamps will flash four times. Once raising is
completed, the horn will chirp one time.
NOTE:More information on air suspension is provided
later in this manual, see Ú
page 165.

Replacing The Battery In The Key Fob
The replacement battery model is one CR2450
battery.
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 for further information.
Do not touch the battery terminals that are on
the back housing or the printed circuit board.
Do not replace the coin battery if the LED on the
key fob above the top row buttons blinks when
a button is pressed. The coin battery should last
a minimum of three years with normal vehicle
usage.

1. Remove the emergency key (1) by pushing the emergency key release button (2) on the
side of the key fob, and pulling the emergency
key out with your other hand.
Emergency Key Removal

2. Hold the key fob with the button side facing down, and locate the small rectangular gap on
the left side between the housing and the back
cover of the key fob. Use a small screwdriver
(or similar tool) to pry open the left side of the
fob cover while applying pressure until the
cover snaps open.
3. Next, locate the gap on the right side of the key fob, which is positioned further to the edge
than the left side gap. Pry open the right side,
and remove the back cover. 4. Remove the battery by using your thumb to
slide the battery downward and back toward
the key ring.

Key Fob Battery Location
NOTE:When replacing the battery, ensure the (+) sign on
the battery is facing upward. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean
it with rubbing alcohol.

6. To assemble the key fob case, line up the top edge of the back cover with the top of the fob,
and press the edges into the interlocking
hinges until all edges snap together with no
large visual gaps.
7. Reinsert the emergency key until it locks into place.
NOTE:The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.
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 repurposed and reprogrammed to
another vehicle.
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle. Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has never
been programmed.
NOTE:
When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.
Keys must be ordered to the correct key cut to
match the vehicle locks.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell battery is
swallowed, it can cause severe internal burns
in just two hours and can lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from
children. If the battery compartment does not
close securely, stop using the product and
keep it away from children.
WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.
Always remember to place the Keyless
Enter ‘n Go Ignition™ in the OFF position.

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.
Normally, the OBD II system will be ready. The
OBD II system may not be ready if your vehicle was
recently serviced, recently had a depleted battery
or a battery replacement. 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 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 Malfunction
Indicator Light (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.
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.

MAINTENANCE PLAN
Refer to the Maintenance Plan for required maintenance. More frequent maintenance may be needed in severe conditions, such as dusty areas and very short
trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be required.
NOTE:Using white lithium grease, lubricate the door hinge roller pivot joints twice a year to prevent premature wear.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change the oil and filter.
Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
Inspect the battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect the brake pads, shoes, rotors, drums, and hoses.
Inspect the engine cooling system protection and hoses.
Inspect the exhaust system.
Inspect the engine air cleaner if using in dusty or off-road conditions, replace the engine air cleaner, as necessary.
Inspect and replace the Evaporative System Fresh Air Filter as necessary; replacement may be more frequent if vehicle is operated in extreme dusty condi-
tions.
