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

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.

GETTING TO KNOW YOUR VEHICLE23
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. Therefore,
only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The
system cannot reprogram a key fob obtained from
another vehicle.
After placing the ignition in the ON/RUN position,
the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on
after the bulb check, it indicates that there is a
problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than
10 seconds), it indicates that there is a fault in the
electronics. Should this occur, have the vehicle
serviced as soon as possible by an authorized
dealer. All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics
Ú
page 480.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button as long as
the key fob is in the passenger compartment.
The START/STOP ignition button has several
operating modes that are labeled and will
illuminate when in position. These modes are OFF,
ACC, ON/RUN, and START.

Keyless Push Button Ignition
The push button ignition can be placed in the
following modes:
OFF

The engine is stopped
Some electrical devices (e.g. power locks,
alarm, etc.) are still available
ACC
Engine is not started
Some electrical devices are available
(e.g. power sunroof, power windows, etc.)
ON/RUN
Driving position
All electrical devices are available (e.g. climate
controls, heated seats, etc.)
START
The engine will start (when foot is on the brake)
NOTE:If the ignition switch does not change the mode by
pushing the button, the key fob may have a low or
depleted battery. In this situation, a back up
method can be used to operate the ignition switch.
Put the nose side (side opposite of the emergency
key) of the key fob against the START/STOP
ignition button and push to operate the ignition
switch.
CAUTION!

The Sentry Key Immobilizer system is not

NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake
Force Distribution (EBD). In the event of an EBD
failure, the Brake Warning Light will turn on along
with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the OFF
position to the ON/RUN position. The light should
illuminate for approximately two seconds. The light
should then turn off unless the parking brake is
applied or a brake fault is detected. If the light does
not illuminate, have the light inspected by an
authorized dealer. The light also will turn on when the parking brake
is applied with the ignition switch in the ON/RUN
position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake appli
-
cation.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays
on while the engine is running, there may
be a malfunction with the charging
system. Contact an authorized dealer as soon as
possible.
This indicates a possible problem with the
electrical system or a related component.

Engine Check/Malfunction Indicator
Warning Light (MIL)
The MIL is a part of an Onboard
Diagnostic System called OBD II that
monitors engine and automatic
transmission control systems. This
warning light will illuminate when the ignition is in
the ON/RUN position before engine start. If the
bulb does not come on when turning the ignition
switch from OFF to ON/RUN, 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 MIL may flash to
alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced
by an authorized dealer as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher
temperatures than in normal operating
conditions. This can cause a fire if you drive
slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could
result in death or serious injury to the driver,
occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the
vehicle control system. It also could affect fuel
economy and driveability. If the MIL is flashing,
severe catalytic converter 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 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.
