Downloaded from www.Manualslib.com manuals search engine To replace the battery in the Keyless Entry System:
1. Use a small coin or flathead screwdriver to separate
the bottom half from the top half
of the transmitter.
2. Remove the battery and replace it with the new one.
Make sure
the positive (+) side of the battery faces
down. Use one
3 volt, CR2032, or equivalent,
type battery.
3. Put the two halves back together. Make sure the
cover is on tightly,
so water won't get in.
4. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
synchronizing the transmitter with the receiver.
Synchronization
Your keyless entry system is equipped with a security
system that prevents anyone from recording and playing
back your signal. The transmitter does not send the same
signal twice to
the receiver. The receiver will not
respond to a signal that has been sent to it more
than once.
To synchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the
LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for five seconds. In this time, the
doors should lock and unlock once.
This confirms
the resynchronization. If the doors do not lock and
unlock, see your dealer for service.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other.
AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be
loud and harmful to your hearing. Take precautions
by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.

Here are some tips for winter driving:
e Have your vehicle in good shape for winter.

clothing, a small shovel, a flashlight,
a red cloth and a
couple of reflective warning triangles. And, if you

Things you put inside your vehicle can strike
and injure people in
a sudden stop or turn, or in
a crash.
0 Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can,
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them are
above the tops

Towing a Trailer
I
A CAUTION:
I
’ If you don’t use the correct equipment and drive
~ properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
~ brakes may not work well -- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull
a trailer only if you have followed all the
steps in this section. Ask your dealer
for advice
and information about towing a trailer with
your vehicle,
Do not tow a trailer if your vehicle is equipped with the
2.4L engine.

Downloaded from www.Manualslib.com manuals search engine Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and follow the instructions for the trailer
brakes
so you’ll be able to install, adjust and maintain
them properly. And because you have anti-lock brakes,
do not
try to tap into your vehicle’s brake system. If you
do, both systems won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight
of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform (and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure the brakes are working.
This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes are still working.

Downloaded from www.Manualslib.com manuals search engine To help avoid inpry to you or others:
0 Never let passengers ride in a vehicle that is
Never tow faster than safe or posted speeds.
Never tow with damaged parts not
fully secured.
0 Never get under your vehicle after it has
been lifted by the tow truck.
0 Always secure the vehicle on each side with
separate safety chains when towing it.
Never use J-hooks. Use T-hooks instead.
being towed.
A CA TION:
A vehicle can fall from a
car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, turn the ignition key
to ACC. The steering wheel should be clamped in a
straight-ahead position, with
a clamping device
designed for towing service. The transaxle should be in
NEUTRAL (N) and the parking brake released.
