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 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:
•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.
•Mobil Speedpass™, 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 keybeing used when starting the
vehicle. Also, cell phones, pagers, or other RF electron-
ics will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.

bulb. If an indicator fails to light when the lever is
moved, it would suggest that the fuse or indicator bulb is
defective.
NOTE:A tone will chime if the turn signals are left on
for more than 1 mile (2 km).
Daytime Running Lights — Canada Only
The headlights come on at a low intensity level after the
vehicle has been driven approximately 3 feet (1 meter).
They will turn off when the vehicle is turned off or when
the headlights are switched on.
WINDSHIELD WIPERS AND WASHERS
CAUTION!
In cold weather, always turn off the wiper switch
and allow the wipers to return to the park position
before turning off the engine. If the wiper switch is
left on and the wipers freeze to the windshield,
damage to the wiper motor may occur when the
vehicle is restarted.
Intermittent Wiper System
Use the intermittent wiper when weather conditions
make a single wiping cycle, with a variable pause be-
tween cycles, desirable. Move the lever to the DELAY
position, then select the delay interval by turning the end
of the lever. The delay can be regulated from a maximum
of approximately 18 seconds between cycles, to a cycle
every second.

13. Oil Pressure Gauge
Indicates engine oil pressure. This gauge does not
indicate oil level, and pressure varies with engine
speed, temperature and oil viscosity. Consistent lower
readings indicate possible malfunction. Seek authorized
service.
14. Coolant Temperature Gauge
Indicates engine coolant temperature. The red
zone to the far right indicates possible overheat-
ing. Seek authorized service immediately if the
gauge operates in the red zone. In U.S. vehicles, tempera-
ture is indicated in degrees fahrenheit; in Canadian
vehicles in degrees centigrade.
15. Airbag Warning Light
This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If
the light does not come on for 6 to 8 seconds,stays on or comes on while driving, have the airbag
system checked by an authorized dealer.
16. Check Gauges Warning Light
This light monitors the engine coolant tem-
perature, engine oil pressure, and voltage
gauges. If it detects an extreme condition a
chime will sound and the light will come on. If the light
comes on, check the operation of these gauges for a
malfunction condition.
17. Malfunction Indicator Light
This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine, and
automatic transmission control systems. The light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the key from OFF to ON, have the condition
checked promptly.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off the

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
•Store the removed IOD fuse in the Power Distribution
Center location #11 labeled “IOD Storage.”
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
