Key-In-Ignition Reminder
If you open the driver’s door and the key is fully inserted
in the ignition switch, a chime will sound to remind you
to remove the key.
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIS) prevents
unauthorized operation of the vehicle by disabling the
engine. The system will shut the engine down after 2
seconds of running if an invalid key is used to start the
vehicle. This system utilizes ignition keys which have an
electronic chip (transponder) embedded into them. Only
keys that have been programmed to the vehicle can be
used to start and operate the vehicle for longer than the
2 second validation time period.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the “Sentry Key/Security Alarm Indicator Light” (located in the instru-
ment cluster) will come on for 3 seconds immediately
after the ignition switch is turned on for a bulb check.
Afterwards, if the bulb remains on, this indicates a
malfunction in the electronics. If the bulb begins to flash
immediately after the ignition switch is turned on, this
indicates that an invalid key is being used to start the
vehicle. Both of these conditions will result in the engine
being shut down after 2 seconds of running. Keep in
mind that a key which has not been programmed is also
considered an invalid key even if it is cut to fit the
ignition for that vehicle.
If the “Sentry Key/Security Alarm Indicator Light”
comes on during normal vehicle operation (it has been
running for longer than 10 seconds) a fault has been
detected in the electronics and the vehicle should be
serviced as soon as possible.

consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed.
NOTE:When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.
Customer Key Programming
You can program new keys to the system if you have two
valid keys by doing the following:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chimewill sound and the “Sentry Key/Security Alarm Indica-
tor Light” will begin to flash. Turn the ignition switch
OFF and remove the second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The “Sentry Key/
Security Alarm Indicator Light” will stop flashing, turn
on for 3 seconds; then turn off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.

the vehicle’s handling and stopping ability. Each tire,
including the spare, should be checked monthly when
cold and set to the recommended inflation pressure as
specified on the vehicle placard. (See page 268 for more
information.)
6. 4LO Mode Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4 LO four–wheel drive mode. The front and

gether forcing the front and rear wheels to
rotate at the same speed. (See page 236 for more infor-
mation.)
7. Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.8. Malfunction Indicator Light

matic transmission control systems. This light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.
Certain conditions such has a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after

stays on through several typical driving cycles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the “Malfunction Indicator

off. If the light remains lit with the engine running your
vehicle will usually be drivable, however, see your dealer
for service as soon as possible. If the light is flashing
when the engine is running, immediate service is re-
quired and you may experience reduced performance, an

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indicator
Light” on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
cap until aclickingsound is heard. This is an indication
