GETTING TO KNOW YOUR VEHICLE15
To Lock The Doors And Tailgate
Push and release the lock button on the key fob
to lock all doors, the tailgate, and the RamBox
(if equipped). The turn signal lights will flash and
the horn will chirp to acknowledge the signal.
Sound Horn With Remote Key Lock — If
Equipped
This feature will cause the horn to chirp when
the doors are locked with the key fob. This
feature can be turned on or turned off through
the Uconnect settings.
NOTE:
Pushing the lock button on the key fob while you
are in the vehicle will activate the vehicle secu -
rity alarm system. Opening a door with the
vehicle security alarm system activated will
cause the alarm to sound. Push the unlock
button to deactivate the vehicle security alarm
system.
Refer to “Vehicle Security Alarm” in this chapter
for further information.
Using The Panic Alarm
To turn the Panic Alarm feature on or off, push
the Panic button on the key fob. When the Panic
Alarm is activated, the turn signals will flash, the horn will pulse on and off, and the interior lights
will turn on.
The Panic Alarm will stay on for three minutes
unless you turn it off by either pushing the Panic
button a second time or drive the vehicle at a
speed of 15 mph (24 km/h) or greater.
NOTE:
The interior lights will turn off if you place the
ignition in the ACC or ON/RUN position while
the Panic Alarm is activated. However, the
exterior lights and horn will remain on.
You may need to be less than 35 ft (11 m)
from the vehicle when using the key fob to
turn off the Panic Alarm due to the radio
frequency noises emitted by the system.
Replacing The Battery In The Key Fob With
Remote Control
The replacement battery model is one CR2032
battery.
NOTE:
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.

1. Remove the emergency key by pushing and holding the release button located on
the side of the key fob while pulling the
emergency key out with your other hand.

5. Replace the battery by pushing the new
battery down on an angle toward the top
edge of the opening. Then, push down on
the remainder of the battery to lock into
place.

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 inter -
locking hinges until all edges snap together
with no large visual gaps.
NOTE:
The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer. Alternative Back Cover Removal Method:
The back cover of the key fob can also be
removed by inserting the emergency key into
the left or right side open slots, and twisting to
pop off the cover.

Alternate Key Fob Back Cover Removal Method

NOTE:
The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.
Programming 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.

technician in making repairs. Although your
vehicle will usually be drivable and not need
towing, see an authorized dealer for service as
soon as possible.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (OBD II) and a connection
port to allow access to information related to
the performance of your emissions controls.
Authorized service technicians may need to
access this information to assist with the diag-
nosis and service of your vehicle and emissions
system. For further information, refer to “Cybersecurity”
in “Multimedia”.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement
to pass an inspection of your vehicle's emis
-sions 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.
CAUTION!
Prolonged driving with the MIL 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 performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems, including safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an acci -
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

GETTING TO KNOW YOUR INSTRUMENT PANEL143
2. As soon as you cycle the ignition switch to
the ON position, you will see the “Malfunc -
tion 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.
