Operation Battery Replacement

button.
If you press this button again within five seconds, all the
remaining doors (except the third door)
will unlock. The

Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any remaining transmitters with you when you
go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have
only four transmitters
matched to it. Under normal use,
the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If
you have to
get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.
Use one three volt, type CR2032, or equivalent battery.

To replace the battery: Synchronization
1. Insert a small coin, or flathead screwdriver, to
separate the bottom of the transmitter from
the top.
making sure the positive
(+) side of the battery is
facing down.
2. Remove the battery and replace it with a new one,
3. Snap the top and bottom together.
4. Test the operation of the transmitter with your
vehicle.
If the transmitter does not work, try
synchronizing the transmitter
with the receiver. Synchronization
may be necessary due to the security
method used
by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the
LOCK
and UNLOCK buttons on the transmitter for at least
five seconds. The door locks should cycle to confirm
synchronization.
If the locks do not cycle, see your
dealer for service.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.

Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for
joy riders or professional thieves -- so
don’t do it.
When you park your vehicle and open the driver’s door, you’ll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition.
If you have an automatic transmission, taking
your key out also locks your transmission. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best to lock it
up and take your keys.
But what
if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your
glove box.
Lock all the doors except the driver’s.
New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” But it will perform better in the long
run
if you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (805 km).
Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
0 Don’t tow a trailer during break-in. See
“Towing a Trailer’’ in the Index for
more information.
a Avoid making hard stops for the first

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal
links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse
with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can “borrow” one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block access door
is on the driver’s side edge
of the instrument panel. Pull
off the cover to access the
fuse block.
You can remove fuses
with a fuse extractor. The fuse
extractor is mounted to the fuse block access door.
To
remove fuses if you don’t have a fuse extractor, hold the
end
of the fuse between your thumb and index finger
and pull straight out.
You may have spare fuses located behind the fuse block
access door. These can be used to replace a bad fuse.
However, make sure
it is of the correct amperage.
