NOTE:Do not touch the battery terminals that are on
the back housing or the printed circuit board.
1. With transmitter buttons facing down, use a flat blade
or dime to pry the two halves of the transmitter apart.
Make sure not to damage the rubber gasket during
removal.
2. Remove and replace the batteries. Be careful not to
disturb the metal terminal near the batteries. Install the
batteries with the positive terminal up, reference the note
+ SIDE UPon the inside of the bottom half of the
transmitter case. Avoid touching the new batteries with
your fingers. Skin oils may cause battery deterioration. If
you touch a battery, clean it with rubbing alcohol.
3. To reassemble the transmitter case snap the two halves
together. Make sure there is an even gap between the two
halves. Test transmitter operation.SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors and ignition for
unauthorized operation. When the alarm is activated, the
system provides both audible and visual signals. For the
first 3 minutes the horn will sound and the headlights
and security telltale will flash repeatedly. For an addi-
tional 15 minutes only the headlights and security telltale
will flash. The engine will run only if a valid Sentry Key
is used to start the vehicle. Use of the Sentry Key will
disable the alarm.
Rearming of the System:
The security system will rearm itself after the 15 addi-
tional minutes of headlights and security telltale flashing,
if the system has not been disabled. If the condition
which initiated the alarm is still present, the system will
ignore that condition and monitor the remaining doors
and ignition.

The Window Airbag System, on vehicles equipped,
consists of the following:
•AIRBAG Readiness Light (shared with the front airbag
system)
•Window Bags Above the Side Windows.
•Airbag Control Module (shared with the front airbag
system)
•Side impact sensors
•Interconnecting Wiring
How The Airbag System Works
•
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
•The airbag control module will not detect roll over, or
rear collisions.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in theOffposition, in
the ACC position or not in the ignition, the airbags are
not on and will not inflate
•The airbag control module also turns on the AIR BAG
light in the instrument panel for 6 to 8 seconds when
the ignition is first turned on, then turns the light off.
•If it detects a malfunction in any part of the
system, it turns on the light either momen-
tarily or continuously. The instrument clus-
ter will flash the seat belt indicator if it
detects a fault with the airbag indicator.

Window Airbags Supplemental Restraint System
(SRS)—If Equipped
The window airbag control module determines if a side
collision is severe enough to require the side airbags to
inflate. The window airbag control module will not
detect roll over, front or rear collisions.
The airbag control module monitors the readiness of the
electronic parts of the system whenever the ignition
switch is in theSTARTorRUNpositions. These
include all of the items listed above. The airbag control
module also turns on the AIRBAG light in the instrument
panel for 6 to 8 seconds when the ignition is first turned
on as a diagnostic or system check, then turns the light
off. If it detects a malfunction in any part of the system,
it turns on the light either momentarily or continuously.
The side (window) impact SRS Airbags are designed to
activate only in certain side collisions. When the airbag
control module detects a collision requiring the windowbags to inflate, it signals the inflators on the crash side of
the vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the side pillar molding out of the way and covers
the window. The airbag inflates in about 30 milliseconds
(about one-quarter of the time it takes to blink your eyes)
with enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies to
children. The window bag is only about 3
1 2inches (8.9
cm) thick when it is inflated.
Enhanced Accident Response System
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 10 seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
