2-7 Rear Door Security Locks (4-Door Models)
Your vehicle is equipped
with rear door security
locks that help prevent
passengers from opening
the rear doors of your
vehicle from the inside.
The switch is located on the inside of the rear door.
To use the security locks:
1. Move the switch up.
2. Close the door.
3. Do the same thing on the other rear door.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open a rear door when the security lock is on:
1. Unlock the door from the inside.
2. Then open the door from the outside.If you don't cancel the security lock feature, adults or
older children who ride in the rear won't be able to open
the rear door from the inside. You should let adults and
older children know how these security locks work, and
how to cancel the locks.
To cancel the rear door lock:
1. Unlock the door from the inside and open it from
the outside.
2. Move the switch down.
3. Do the same for the other rear door.
The rear doors will now work normally.
Anti-Lockout Protection
Anti-Lockout Protection is a standard feature intended
to provide enhanced security and convenience. This
feature prevents a driver who has left the keys in the
ignition from locking the doors using the power door
locks while any door is open.
To override this feature, when the key is in the ignition
and a door is open, hold the power door lock switch in
the lock position for three seconds.

To replace the battery in the remote lock
control transmitter:
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 three
-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. Resynchronize and then test the transmitter.
Resynchronization
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 resynchronize 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.

Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation. You'll
have a lot less traction or ªgripº and will need to be
very careful.
