A WORD ABOUT YOUR KEYS
Your vehicle uses either a key start ignition system or
keyless ignition system. The key start ignition system
consists of a either a bladed key with an immobilizer chip
in it, or a Key Fob with Remote Keyless Entry (RKE)
transmitter and an Ignition Node Module (IGNM). The
keyless ignition system consists of a Key Fob with
Remote Keyless Entry (RKE) transmitter and a Keyless
Push Button Ignition.
Ignition Node Module (IGNM)
The Ignition Node Module (IGNM) operates similar to an
ignition switch. It has four operating positions, three with
detents and one that is spring-loaded. The detent posi-
tions are OFF, ACC, and ON/RUN. The START position
is a spring-loaded momentary contact position. When
released from the START position, the switch automati-
cally returns to the ON/RUN position.Ignition Module

12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

SENTRY KEY®
The Sentry Key® Immobilizer System prevents unau-
thorized 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 with a factory-mated Remote
Keyless Entry (RKE) transmitter, an Ignition Node Mod-
ule, 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
to start 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 turning on the ignition
switch, 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 that there is a fault in the electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.

CAUTION!
The Sentry Key® Immobilizer system is not compat-
ible with some aftermarket remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: 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.
CAUTION!
• Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
• For vehicles equipped with Keyless Enter-N-Go™,
always remember to place the ignition in the OFF
position.
NOTE: Duplication of Key Fobs may be performed at an
authorized dealer. This procedure consists of program-
ming a blank Key Fob to the vehicle electronics. A blank
Key Fob is one that has never been programmed.
When having the Sentry Key® Immobilizer System ser-
viced, bring all vehicle keys with you to an authorized
dealer.
