GETTING TO KNOW YOUR VEHICLE
KEYS
KEY FOB
Your vehicle is equipped with a key fob which
supports Passive Entry, Remote Keyless Entry
(RKE), Keyless Enter-N-Go (if equipped), and
Remote Start (if equipped). The key fob allows
you to lock or unlock all doors, tailgate, and the
RamBox (if equipped) as well as activate the
Panic Alarm from distances up to approximately
66 ft (20 m). The key fob does not need to be
pointed at the vehicle to activate the system. The
key fob also contains an emergency key, which is
stored in the rear of the key fob.
NOTE:
The key fob’s wireless signal may be blocked if
the key fob is located next to a mobile phone,
laptop, or other electronic device. This may
result in poor performance.
If your vehicle is equipped with a Wireless
Charging Pad, the key fob may not be found if
it is placed within 15 cm (150 mm) of the pad
Ú page 77.
With the ignition in the ON position and the
vehicle moving at 2 mph (4 km/h), all RKE
commands are disabled.
Key Fob
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, 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.

Úpage 237.
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
(Park) ride height.
The vehicle battery must be fully charged.
All doors must be closed.
The key fob must be out of the vehicle.
NOTE:
Ensure the vehicle is clear of all objects, pets,
and people prior to remote lowering.
Canceling Remote Lowering
Vehicle lowering can be cancelled at anytime.
When vehicle lowering is cancelled, the vehicle
will raise up to the next defined level and lock
out the remote lowering feature until the
ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the key fob air
suspension lowering button one time during the
lowering process. When vehicle lowering is
cancelled, 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 Ú
page 165.
Replacing The Battery In The Key Fob
The replacement battery model is one CR2450
battery.

apply. See www.dtsc.ca.gov/hazard -
ouswaste/perchlorate for further informa -
tion.
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.

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.
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 Ú
page 482.
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.
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 switch 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 482.
WARNING!
Always remove the key fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.
For vehicles equipped with Keyless
Enter-N-Go — Ignition, always remember to
place the ignition in the OFF mode.
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.

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. central locking,
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 the 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.

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.
Engine starting procedure Ú
page 140.
When opening the driver's door and the igni -
tion is in the ON/RUN position (engine not
running), a chime will sound to remind you to
place the ignition in the OFF position. In addi -
tion to the chime, the message “Ignition or
Accessory ON” will display in the cluster.
REMOTE START — IF EQUIPPED
(GASOLINE)
This system uses the key fob to start
the engine conveniently from outside
the vehicle while still maintaining
security. The system has a range of
approximately 300 ft (91 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.
HOW TO USE REMOTE START
Push and release the Remote Start button on
the key fob twice within five seconds. The
vehicle doors will lock, the parking lights will
flash, and the horn will chirp twice (if
programmed). Then, the engine will start, and
the vehicle will remain in the Remote Start
mode for a 15 minute cycle.
Pushing the remote start button a third time
shuts the engine off.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren, and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go
in the ON/RUN mode. A child could operate
power windows, other controls, or move the
vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
An unlocked vehicle is an invitation for
thieves. Always remove key fob from the
vehicle and lock all doors when leaving the
vehicle unattended.
WARNING!
(Continued)
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous and can cause serious injury or
death when inhaled.
Keep key fobs away from children. Opera -
tion of the Remote Start System, windows,
door locks or other controls could cause
serious injury or death.
