when the key is in the ignition and a door is open to
protect you from locking your key in the vehicle.If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock and

door and set the locks from inside. Then get out and
close the door.

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 chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your ignition and transmission will be locked. Also
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
Even if you park in a lot where someone will be
watching your vehicle, it's still 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.

If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.

Content Theft-Deterrent (If Equipped)
Your vehicle may be equipped with a content
theft
-deterrent alarm system.
United States Canada
With this system, the SECURITY light will flash as you
open the door (if your ignition is off).
This light reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.
3. Close all doors. The SECURITY light should go off
after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will flash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power.
Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.

Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any door
with the key. You can also turn off the alarm by
pressing unlock on the remote keyless entry
transmitter. The alarm won't stop if you try to unlock
a door any other way.

2-17
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
When the alarm is set the power door unlock switch is
not operational.
If the alarm does not sound when it should but the
headlamps flash, 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 alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer.
Passlock

Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, the fuel system is disabled
and the vehicle will not start.
During normal operation, the SECURITY light will
turn off approximately five seconds after the key is
turned to RUN.
If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing
before trying to restart the engine. Remember to release
the key from START as soon as the engine starts.

2-19
Ignition Positions
Use the key to turn the ignition switch to four
different positions.
A (Lock): This position locks the ignition and
transmission. It's a theft
-deterrent feature. You will
only be able to remove the key when the ignition is
turned to LOCK.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.
B (Accessory): This position lets you use things like the
radio and the windshield wipers when the engine is off.
NOTICE:
Don't operate accessories in the ACCESSORY
position for long periods of time. Prolonged
operation of accessories in the ACCESSORY
position could drain the battery and prevent you
from starting your vehicle.
C (Run): This is the position for driving.
D (Start): This position starts the engine.

2-20
Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features
of your vehicle to continue to work up to 20 minutes
after the ignition key is turned to LOCK.
Your radio, power windows, sunroof (option) and
overhead console will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned from
RUN to LOCK, these features will continue to work for
up to 20 minutes or until a door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor. At 15 seconds, the
starter will automatically be disengaged. Wait
about 15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start within 10 seconds, push the
accelerator pedal all the way to the floor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.
