Key-In-Ignition Reminder
Opening the driver's door when the key is in the ignition,
sounds a signal to remind you to remove the key.
CAUTION!
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
SENTRY KEY IMMOBILIZER SYSTEM Ð IF
EQUIPPED
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 automaticregardless of whether or not the vehicle is locked or
unlocked. During normal operation, the SKIS indicator
light 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 SKIS 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.
NOTE:
²
The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²Mobil SpeedpassŸ, additional Sentry Keys, or any
other transponder equipped components on the same
keychain will not cause a key-related (Transponder)
fault unless the additional part isphysically held
against the ignition key
being used when starting
the vehicle. Also, cell phones, pagers, or other RF
electronics will not cause interference with this
system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Important Note About Service
A four digit PIN number is needed to service the Sentry
Key Immobilizer System. This number can be obtained
from your authorized dealer. However, this number can
also be found on your customer invoice that you were
given upon receipt of your vehicle.
Replacement Keys
NOTE:
Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it cannot
be programmed to any other vehicle.At the time of purchase, the original owner is provided
with a four digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure
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 chime
will sound and the SKIS indicator 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 SKIS 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.
General Information
The Sentry Key Immobilizer System complies with FCC
rules part 15 and with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
STEERING WHEEL LOCK Ð IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock (manual transmission only). This lock pre-
vents steering the vehicle without the ignition key. If the
steering wheel is moved a half turn in either direction
and the key is not in the ignition, the steering wheel will
lock.
To Manually Lock the Steering Wheel
With the engine running, rotate the steering wheel 1/2
revolution from straight ahead position, turn off the
engine and remove the key. Rotate the steering wheel
slightly in both directions until the lock engages.
To Release the Steering Wheel Lock
Insert the key in the ignition and turn the wheel slightly
to the right or left to disengage the lock.
NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.

INSTRUMENT CLUSTER DESCRIPTION
Your vehicle is equipped with the instrument cluster
described on the following pages.
1. Voltmeter
Indicates available battery voltage and charging
system operation. The lower red zone indicates
that battery charge may be too low to start the engine.
With the engine running, the normal operating range
is between 11 and 15 volts. Prolonged gauge readings
between 8-11 (undercharge) or above 15 (overcharge)
indicate possible malfunction of generator, voltage
regulator or battery. See your dealer if such indications
occur.
2. Front Fog Light Indicator Light Ð If Equipped
This light shows when the front fog lights are
on.
3. Cruise Indicator Light
This light shows when the electronic speed
control system is turned on.4. Sentry Key Indicator Light Ð If Equipped
Refer to ªSentry Key Immobilizer Systemº in
Section 2 of this manual.
5. Tachometer
Indicates the engine speed in revolutions per minute
(RPM).
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
6. Turn Signal Indicator Lights
The arrows will flash with the exterior turn sig-
nals when the turn signal lever is operated. A tone
will chime if the turn signals are left on for more than
1 mile (2 km).
