GETTING TO KNOW YOUR VEHICLE17
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.
5. Replace the battery by using your thumb to
push down and slide the battery under the
small lip on the top edge of the opening.

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.
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 chil -
dren. 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.

18GETTING TO KNOW YOUR VEHICLE
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.
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 412.
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 Remote Keyless Entry key fob is in the
passenger compartment.
The Keyless Push Button Ignition has four
operating positions; three of which are labeled and will illuminate when in position. The three positions
are OFF, ACC, and ON/RUN. The fourth position is
START. During START, RUN will illuminate.
NOTE:In case the ignition switch does not change with
the push of a 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, with your foot applied on the brake
pedal, and push to operate the ignition switch.

Keyless Push Button Ignition

CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket Remote Start
systems. Use of these systems may result in
vehicle starting problems and loss of security
protection.

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 driver enters the
vehicle.
NOTE:Obstructions between the vehicle and the key fob
may reduce this range Ú page 412.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The parking
lights will flash, vehicle doors will lock, and the
horn will chirp twice (if programmed). Once the
vehicle has started, the engine will run for
15 minutes.
Pushing the Remote Start button a third time shuts
the engine off.
To drive the vehicle, push the unlock button, and
place the ignition in the ON/RUN position.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in
10 seconds.
The parking lights will turn on and remain on
during Remote Start mode.
For security, power window operation is
disabled when the vehicle is in the Remote Start
mode.
The ignition must be placed in the ON/RUN posi -
tion before the Remote Start sequence can be
repeated for a third cycle.
If your power door locks were unlocked, Remote
Start will automatically lock the doors.
All of the following conditions must be met before
the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not pressed)
Battery at an acceptable charge level
PANIC button not pushed
Fuel meets minimum requirement
System not disabled from previous Remote
Start event
Vehicle Security system not active
Malfunction Indicator Light (MIL) is not illumi -
nated
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. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.

REMOTE START ABORT MESSAGE
The following messages will display in the
instrument cluster display if the vehicle fails to
remote start or exits Remote Start prematurely:
Remote Start Cancelled — Door Open
Remote Start Cancelled — Hood Open
Remote Start Cancelled — Fuel Low
Remote Start Cancelled — System Fault
Remote Start Disabled — Start Vehicle to Reset
The instrument cluster display message stays
active until the ignition is placed in the ON/RUN

REMOTE START — IF EQUIPPED (DIESEL)
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 driver enters the
vehicle.
NOTE:
Obstructions between the vehicle and the key
fob may reduce this range.
The Remote Start system will wait for the Wait
To Start Light Úpage 101 to extinguish before
cranking the engine. This allows time for the
intake heater to preheat the incoming air, and is
normal operation in cold weather Ú page 412.
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
