Sound Horn with Remote Key Lock
This feature will cause the horn to chirp when the doors
are locked with the transmitter. This feature can be
turned on or turned off. To change the current setting,
proceed as follows:
•For vehicles equipped with the Electronic Vehicle
Information Center (EVIC), refer to “Sound Horn with
Remote Key Lock,” under “Personal Settings (Cus-
tomer Programmable Features),” under “Electronic
Vehicle Information Center (EVIC)” in Section 4 of this
manual for details.
•For vehicles not equipped with the EVIC, perform the
following steps:
1. Press the LOCK button on a programmed transmitter
for at least 4 seconds, but no longer than 10 seconds.
Then, press the PANIC button while still holding the
LOCK button.2. Release both buttons at the same time.
3. Test the feature while outside of the vehicle, by
pressing the LOCK button on the transmitter with the
ignition switch in the LOCK position, and the key
removed.
4. Repeat these steps if you want to return this feature to
its previous setting.
NOTE:Pressing the LOCK button on the transmitter
while you are in the vehicle will activate the Security
Alarm. Opening a door with the Security Alarm activated
will cause the alarm to sound. Press the UNLOCK button
to deactivate the Security Alarm.

TRUNK SAFETY WARNING
WARNING!
Do not allow children to have access to the trunk,
either by climbing into the trunk from outside, or
through the inside of the vehicle. Always close the
trunk lid when your vehicle is unattended. Once in
the trunk, young children may not be able to escape,
even if they entered through the rear seat. If trapped
in the trunk, children can die from suffocation or
heat stroke.
Trunk Emergency Release
The trunk of your vehicle is equipped with an emergency
release handle. It is located on the inside of the trunk lid,
near the latch, and is coated so that it glows in a darkened
trunk. Pull on the handle to open the trunk.

Steering Linkage
The tie rod end ball joints should be inspected for
external leakage or damage when other maintenance is
performed.
Body Lubrication
Locks and all body pivot points, including seat tracks,
door hinges, trunk hinges, and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism,
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a smallamount of a high quality lubricant such as MoparLock
Cylinder Lubricant or equivalent directly into the lock
cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
