WARNING!
• Always remove the key fobs from thevehicle and lock all doors when leaving
the vehicle unattended.
• For vehicles equipped with Keyless
Enter-N-Go — Ignition, always remem-
ber to place the ignition in the OFF
mode.
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 Sys-
tem serviced, bring all vehicle keys with you
to an authorized dealer.
IGNITION SWITCH
Models With Keyless Enter-N-Go —
Passive Entry
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 com-
partment.
The push button ignition has three operating
positions. The three positions are OFF, RUN,
and START.
NOTE:
If the ignition switch does not change with
the push of a button, the key fob may have a
low or dead battery. In this situation, a back
up method can be used to operate the igni-
tion switch. Put the nose side (side opposite
of the emergency key) of the key fob against
the ENGINE START/STOP button and push to
operate the ignition switch. The push button ignition can be placed in the
following positions:
OFF
• The engine is stopped.
• Some electrical devices (e.g. Central lock-
ing, alarm, etc.) are still available.

Changes or modifications not expressly ap-

ance could void the user’s authority to oper-
ate the equipment.
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.
All of the key fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Irregular Operation
The system uses a key fob, an Ignition Node
Module, Keyless Push Button Ignition and a
RF receiver to prevent unauthorized vehicle
operation. Therefore, only key fobs that are
programmed to the vehicle can be used tostart and operate the vehicle. The system will
not allow the engine to crank if an invalid key
fob is used to start and operate the vehicle.
The system will shut the engine off in two
seconds if an invalid key fob is used to start
the engine.
NOTE:
A key fob that has not been programmed is
also considered an invalid key.
During normal operation, after placing the
keyless 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 used
an invalid key fob to try to start the engine.
Either of these conditions will result in the
engine being 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 thatthere is a fault in the electronics. Should this
occur, have the vehicle serviced as soon as
possible by an authorized dealer.
VEHICLE SECURITY ALARM
— IF EQUIPPED
The Vehicle Security Alarm monitors the ve-
hicle doors, hood, liftgate, and the Keyless
Enter-N-Go — Ignition for unauthorized op-
eration. While the Vehicle Security Alarm is
armed, interior switches for door locks and
liftgate release are disabled. If something
triggers the alarm, the Vehicle Security Alarm
will provide the following audible and visible
signals:
• The horn will pulse
• The park lamps and/or turn signals will
flash
• The Vehicle Security Light in the instru- ment cluster will flash
