General Information

The following regulatory statement applies to all Radio

Frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and

with Industry Canada license-exempt RSS standard(s).

Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, in-

cluding interference that may cause undesired opera-

tion.

NOTE:

Changes or modifications not expressly approved

by the party responsible for compliance could void the

user’s authority to operate the equipment.

SENTRY KEY

The Sentry Key Immobilizer System prevents unauthor-

ized 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 key fobs that have an embedded electronic

chip (transponder) to prevent unauthorized vehicle opera-

tion. Therefore, only key fobs that are programmed to the

vehicle can be used to start and operate the vehicle. The

system will shut the engine off in two seconds if someone

uses an invalid key to try to start the engine.

NOTE:

A key fob that has not been programmed is also

considered an invalid key, even if it is cut to fit the ignition

or lock cylinder for that vehicle.
During normal operation, after placing the ignition in the

on 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 vehicle security light begins

to flash after the bulb check, it indicates that someone used

an invalid key 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 ten 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.
