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.

Key Fob Battery Replacement

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.

22_DT_OM_EN_USC_t.book Page 22

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
compatible with some aftermarket Remote Start

Back Up Starting Method

NOTE:
The key fob may not be detected by the vehicle
Keyless Enter ‘n Go™ system if it is located next
to a mobile phone, laptop or other electronic
device; these devices may block the key fob’s
wireless signal and prevent the Keyless
Enter ‘n Go™ system from starting the vehicle.
For more information on normal engine starting,
see Ú
page 140.
When opening the driver's door and the ignition
is in the ON/RUN position (engine not running),

The system has a range of approximately
328 ft (100 m).
Remote Start is used to defrost windows in cold
weather and to reach a comfortable climate in all
ambient conditions before the customer enters
the vehicle.
NOTE:Obstructions between the vehicle and key fob may
reduce this range Ú page 480.
WARNING!
When exiting the vehicle, always remove the
key fob from the vehicle and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
Allowing children to be in a vehicle unattended
is dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the Keyless Enter ‘n Go Ignition™ in
