Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
Because your vehicle has the theft
-deterrent system, you
must unlock the doors with the key or remote keyless
entry transmitter to avoid setting off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use the
manual lock levers located
on the door panels.
Push down on the manual lock lever to lock the door. To
unlock the door, pull up on the lever.

to unlock the other doors. It will also disarm the
theft
-deterrent system and turn on the interior

Remember, the theft-deterrent system won't arm if you
lock the doors with a key or use the manual door lock. It
activates only if you use a power door lock with the
door open or the remote keyless entry transmitter.
To avoid activating the alarm by accident do
the following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter system. Pressing the unlock
button on the remote keyless entry transmitter
disables the theft
-deterrent system. Unlocking a door
any other way will activate the alarm when a door or
the trunk is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm
by using the unlock button on the remote keyless
entry transmitter system, or by starting the car with a
valid key.
Changes or modifications made to this system by other
than an authorized service facility could void
authorization to use the theft system.
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
remote keyless entry system and close the door.
Wait 30 seconds until the SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
hazard lights will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the
remote keyless entry transmitter or by starting the car
with a valid key.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see ªFuses and Circuit Breakersº in the
Index. If the fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft
-deterrent system when leaving your vehicle.

Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages. See
ªDriver Information Center (DIC)º in the Index for
more information.
