WARNING! (Continued)
•Do not leave the key fob in or near the vehicle, and
do not leave Keyless Enter-N-Go in the ACC or
ON/RUN mode. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove Key Fob from the ignition and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
Opening the driver’s door when the Key Fob is in the
ignition and the ignition switch position is OFF or ACC,
sounds a signal to remind you to remove the Key Fob.NOTE:
The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or ACC ignition
position.
With the Keyless Enter-N-Go feature, opening the driv-
er’s door when the vehicle’s ignition switch is placed in
ACC or ON/RUN (engine stopped) will cause the re-
minder chime to sound. Refer to “Starting Procedures” in
“Starting And Operating” for further information.
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 the factory-mated Key Fob with Remote
Keyless Entry (RKE) transmitter and Wireless Ignition
Node (WIN) to prevent unauthorized vehicle operation.
Therefore, only Key Fobs that are programmed to the
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 turning the ignition switch to the ON/RUN posi-
tion, 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 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 KeyImmobilizer 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.
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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

CAUTION!
•Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
•With Keyless Enter-N-Go, always remember to
place the ignition in OFF.
At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).

required for authorized dealer replacement of Key Fobs.
Duplication of Key Fobs may be performed at an autho-
rized 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.

system serviced, bring all vehicle Key Fobs with you to
the authorized dealer.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.
