10 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

headlights and turn signal lights will flash, the horn will
pulse on and off, and the illuminated entry system will
turn on.
The panic alarm will stay on for 3 minutes unless you
turn it off by pressing the Panic button a second time or
if the vehicle speed is 5 mph (8 km/h) or greater.
During the Panic Mode, the door locks and remote
keyless entry system will function normally. Panic mode
will not disarm the security system on vehicles so
equipped.
NOTE:You may need to be close to the vehicle when
using the transmitter to turn off the panic alarm due to
the radio frequency noises emitted by the system.Programming Additional Transmitters
Refer to SENTRY KEY ªCustomer Key Programming.º
in this section.
NOTE:If you do not have a programmed transmitter,
contact your dealer for details.
Battery Replacement
The recommended replacement battery is CR2032.
NOTE:
²Perchlorate Material Ð special handling may apply.
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
²Do not touch the battery terminals that are on the back
housing or the printed circuit board.

Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap in loose, improperly installed, or damaged, a
ªgASCAPº message will display in the instrument clus-
ter. Tighten the gas cap until a ªclickingº sound is heard.
This is an indication that the gas cap is properly tight-
ened. Press the trip odometer reset button to turn off the
message. If the problem persists, the message will appear
the next time the vehicle is started. This might indicate a
damaged cap. If the problem is detected twice in a row,
the system will turn on the Malfunction Indicator Light
(MIL). Resolving the problem will turn the MIL light off.
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 Light)
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.
400 MAINTAINING YOUR VEHICLE

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
ignition key or start the engine. This means that your
vehicle's OBD system isnot readyand you shouldnot
proceed to the I/M station.b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or start
the engine. This means that your vehicle's OBD system
isreadyand you can proceed to the I/M station.
If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
