18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
The system uses a Key Fob with a factory-mated Remote
Keyless Entry (RKE) transmitter, a Keyless Ignition Node
(KIN) and a RF receiver to prevent unauthorized vehicle
operation. Therefore, only Key Fobs that are pro-
grammed 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 sec-
onds), 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.
CAUTION!
The Sentry Key® Immobilizer system is not compat-
ible with some after-market 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.
