SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
The SecuriLockypassive anti-theft system provides
an advanced level of vehicle theft protection. Your
vehicle's engine can only be started with the two
special SecuriLockyelectronically coded keys
provided with your vehicle. Each time you start your
vehicle, the SecuriLockykey is read by the
SecuriLockypassive anti-theft system. If the
SecuriLockykey identification code matches the
code stored in the SecuriLockyanti-theft system,
the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match
the code stored in the system or if a SecuriLocky
key is not detected (vehicle theft situation), the
vehicle's engine will not operate.
If there is any potential SecuriLockyanti-theft
problem with your vehicle, ensureALL
SecuriLockykeysfor that vehicle are brought to
the dealership, to aid in troubleshooting.

The SecuriLockypassive anti-theft system is not
compatible with aftermarket remote start systems.
Use of these systems may result in vehicle starting
problems and a loss of security protection. Large
metallic objects or devices such as the Mobil
Speedpassyon the same key ring as your
SecuriLockykey may cause vehicle starting
problems. These objects and devices cannot damage
the SecuriLockykey, but can cause a momentary
problem if they are too close to the key when
starting the engine. If a problem occurs, turn
ignition off and restart the engine with all other
objects on the key ring held away from the
SecuriLockyignition key.
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system. Refer to
Programming spare SecuriLockykeysfor more
information.
If one or both of your SecuriLockykeys are lost or
stolen and you want to ensure the lost or stolen key
will not operate your vehicle, bring your vehicle and
all available SecuriLockykeys to your dealership for
reinitialization.
Theft indicator
The theft indicator on the instrument cluster will
operate as follows:
²When the ignition is OFF, the theft indicator will
flash briefly every 2 seconds to indicate the
SecuriLockysystem is protecting your vehicle.
²When the ignition is turned to RUN or START, the
theft indicator will light for 3 seconds and then go
out. If the theft indicator stays on for an extended
period of time or flashes rapidly, have the system
serviced by your dealership or a qualified
technician.

Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system (up to a total
of 8 keys). Your dealership can program your new
SecuriLockykey(s) to your vehicle or you can do it
yourself using the following simple procedure. To
program a new SecuriLockykey yourself, you will
need two previously programmed SecuriLockykeys
(keys that already operate your vehicle's engine). If
two previously programmed SecuriLockykeys are
not available (one or both of your original keys were
lost or stolen), you must bring your vehicle to your
dealership to have the spare SecuriLockykey(s)
programmed.
Procedure to program spare SecuriLockYkeys
to your vehicle
New SecuriLockykeys must have the correct
mechanical key cut for your vehicle.
Conventional (non-SecuriLocky) keyscannotbe
programmed to your vehicle.
You will need to have two previously programmed
SecuriLockykeys and the new unprogrammed
SecuriLockykey readily accessible for the
procedure. Please read and understand the entire
procedure before you begin.
1. Insert the first previously programmed
SecuriLockykey into the ignition and turn the
ignition from OFF to RUN (maintain ignition in RUN
for at least one second).
2. Turn ignition to OFF and remove the first
SecuriLockykey from the ignition.
3. Within five seconds of turning the ignition to OFF,
insert the second previously programmed
SecuriLockykey into the ignition and turn the
ignition from OFF to RUN (maintain ignition in RUN
for at least one second but no more than 5 seconds).
Controls and features
62

4. Turn the ignition to OFF and remove the second
SecuriLockykey from the ignition.
5. Within 10 seconds of turning the ignition to OFF,
insert the unprogrammed SecuriLockykey (new
key/valet key) into the ignition and turn the ignition
from OFF to RUN (maintain ignition in RUN for at
least one second). This step will program your new
SecuriLockykey.
6. To program additional SecuriLockykey(s), repeat
this procedure from step 1.
If the programming procedure was successful, the
new SecuriLockykey(s) will start the vehicle's
engine. The theft indicator (located on the
instrument cluster) will light for three seconds and
then go out.
If the programming procedure was not successful,
the new SecuriLockykey(s) will not operate the
vehicle's engine. The theft indicator will flash on and
off. Wait at least one minute and then repeat the
procedure from step 1. If failure repeats, bring your
vehicle to your dealership to have the spare
SecuriLockykey(s) programmed.

3. Turn the key to 4
(ON) without turning
the key to 5 (START).
Make sure the corresponding lights illuminate briefly.
If a light fails to illuminate, have the vehicle
serviced.
²If the driver's safety belt is fastened, the
light
may not illuminate.

STARTING THE ENGINE
1. Turn the key to 5
(START) without
pressing the
accelerator pedal and
release as soon as the
engine starts. The key
will return to 4 (ON).
2. If the temperature is above ±12ÉC (10ÉF) and the
engine does not start within five seconds on the first
try, turn the key to OFF, wait ten seconds and try
again.
3. If the temperature is below -12ÉC (10ÉF) and the
engine does not start in fifteen seconds on the first
try, turn the key OFF and wait ten seconds and try
again. If the engine does not start in two attempts,
depress the accelerator and start the engine while
holding the accelerator down to the floor. Release
the accelerator when the engine starts.
4. After idling for a few seconds, apply the brake
and release the parking brake.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant,
which improves starting, warms up the engine faster
and allows the heater-defroster system to respond
quickly. Use of an engine block heater is strongly
recommended if you live in a region where
temperatures reach -23ÉC (-10ÉF) or below.
For best results, plug the heater in at least three
hours before starting the vehicle. Using the heater
for longer than three hours will not harm the engine,
so the heater can be plugged in the night before
starting the vehicle.
To prevent electrical shock, do not use your
heater with ungrounded electrical systems
or two-pronged (cheater) adapters.

To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme
right or the extreme left for more than a few
seconds when the engine is running.
²Do not operate the vehicle with a low power
steering pump fluid level.
If the power steering system breaks down (or if the
engine is turned off), you can steer the vehicle
manually, but it takes more effort.
If the steering wanders or pulls, the condition could
be caused by any of the following:
²underinflated tire(s) on any wheel(s)
²high crown in center of road
²high crosswinds
²wheels out of alignment
²loose or worn components in steering linkage
AUTOMATIC TRANSMISSION OPERATION
(IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock
feature that prevents the gearshift from being moved
from P (Park) unless the brake pedal is depressed.
If you cannot move the gearshift out of P (Park)
with the brake pedal depressed:
1. Apply the parking brake, turn ignition key to
LOCK, then remove the key.
2. Insert the key and turn it to OFF. Apply the brake
pedal and shift to N (Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to
move the gearshift, it is possible that a fuse has
blown or the vehicle's brakelamps are not operating
properly. Refer toFuses and relaysin theRoadside
emergencieschapter.

4. Turn the ignition key
to position 3 (OFF).
Do not park your vehicle in Neutral, it may
move unexpectedly and injure someone. Use
1 (First) gear and set the parking brake fully.
Reverse
You can shift into R (Reverse) only by moving the
gearshift to the right of 5 (Fifth) gear before you
shift into R (Reverse). This is a feature that protects
you from accidentally shifting into R (Reverse) when
you downshift from 5 (Fifth).
Make sure that your vehicle is at a complete
stop before you shift into R (Reverse). Failure
to do so may damage the transmission.
To shift into R
(Reverse):
1. Bring your vehicle to
a complete stop.
2. Push the clutch
pedal all the way to the
floor.
3. Move the gearshift
all the way to the right
and pull it back into R
( Reverse).
