the battery. When replacing the battery, match
the (+) sign on the battery to the (+) sign on the

rubbing alcohol.

lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from chil-

Always remember to place the ignition in the

OFF position.
Duplication of key fobs may be performed at an

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 will shut the engine off in two seconds if an
invalid key fob is used to start the engine.
After placing the ignition switch 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 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
electronics. Should this occur, have the vehicle
serviced as soon as possible by an authorized
dealer.
