Content Theft-Deterrent
Your vehicle is equipped with a content
theft-deterrent alarm system.
With this system, the
security light in the
instrument panel cluster
will ash as you open
the door if your
ignition is off.
This light reminds you to activate the
theft-deterrent system. Here is 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 will illuminate to inform the driver
the system is arming. If a door is open when
the doors are locked, the security light
will ash.3. Close all doors. The security light should go
off after about 30 seconds. The alarm is not
armed until the security light goes off.
If the delayed locking feature is turned on,
the theft-deterrent system will not start
the arming process until the last door is
closed and the delay timer has expired.
SeeDelayed Locking on page 102.
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
ash for two minutes, and the horn will sound for
30 seconds, then will turn off to save the battery
power. You can choose different feedback options
for the alarm. SeeDIC Vehicle Customization
on page 234.
Remember, the theft-deterrent system will not
activate if you lock the doors with the vehicle’s 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.

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 ve seconds after the key is
turned to RUN.
If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light comes
on, you will be able to restart the engine if you turn
the engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®
at this time. You may also want to check the fuse.

Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. 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.
Lengthy operation of features such as the radio in
the accessory ignition position and the RUN
position may drain the battery and prevent your
vehicle from starting. Do not operate your vehicle
in the accessory ignition position for a long
period of time.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine
starts, and you release the key.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.
120

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
The Retained Accessory Power (RAP) feature will
allow certain features on your vehicle to continue to
work for up to 10 minutes after the ignition key is
turned to LOCK or until one of the doors is opened.
Starting the Engine
Place the transmission in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position – this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not 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.
Starting Procedure
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. Do not
race the engine immediately after starting it.
Operate the engine and transmission gently to
allow the oil to warm up and lubricate all
moving parts.

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components. If
the ignition key is turned to the START position,
and then released when the engine begins
cranking, the engine will continue cranking for a
few seconds or until the vehicle starts. If the
engine does not start and the key is held in
START for many seconds, cranking will be
stopped after 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine is
already running. Engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts briey but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently until the oil
warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
