start systems. Use of these systems may result in
vehicle starting problems and a loss of security
protection.
Note:Large metallic objects, electronic devices that
are used to purchase gasoline or similar items, or a
second coded key on the same key chain may cause
vehicle starting issues. You need to prevent these
objects from touching the coded key while starting
the engine. These objects will not cause damage to
the coded key, but may cause a momentary issue if
they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off,
remove all objects on the key chain away from the
coded key and restart the engine.
Theft indicator
The theft indicator is located in the instrument
cluster.
•When the ignition is in the OFF position, the
indicator will flash once every 2 seconds to
indicate the SecuriLocksystem is functioning as
a theft deterrent.
•When the ignition is in the ON position, the
indicator will glow for 3 seconds, then turn off to
indicate normal system functionality.
If a problem occurs with the SecuriLocksystem,
the indicator will flash rapidly or glow steadily when
the ignition is in the ON position. If this occurs, the
vehicle should be taken to an authorized dealer for
service.
Automatic arming
The vehicle is armed
immediately after
switching the ignition
to the 3 (OFF)
position.
The
THEFTindicator
will flash every two
seconds when the
vehicle is armed.

Automatic disarming
Switching the ignition to the 4 (ON) position with a
coded keydisarms the vehicle.
•The
THEFTindicator will illuminate for three
seconds and then go out.
•If the
THEFTindicator stays on for an extended
period of time or flashes rapidly, have the system
serviced by your dealer.
Replacement keys
If your keys are lost or stolen and you don’t have an
extra coded key, you will need to have your vehicle
towed to a dealership. The key codes need to be
erased from your vehicle and new coded keys will
need to be programmed.
Replacing coded keys can be very costly. Store an
extra programmed key away from the vehicle in a
safe place to help prevent any inconveniences.
Please visit an authorized dealer to purchase
additional spare or replacement keys.
Programming spare keys
You can program your own coded keys to your
vehicle. Please read and understand the entire
procedure before you begin.
Tips:
•A maximum of eight keys can be coded to your
vehicle.
•Only use Securilockkeys.
•You must have two previously programmed coded
keys (keys that already operate your vehicle’s
engine) and the new unprogrammed key(s)
readily accessible.
•If no previously programmed coded keys are
available, you must take your vehicle to your
dealer to have the spare key(s) programmed.

position for at least one second but not more than
10 seconds.

4 (ON) position. Keep the ignition in the 4 (ON)
position for at least one second.
9. Your new unprogrammed key is now programmed.
If the key has been successfully programmed it will
start the vehicle’s engine and the theft indicator light
will illuminate for three seconds and then go out. If
the key was not successfully programmed, it will not
start your vehicle’s engine and the theft indicator
light will flash on and off rapidly. If failure repeats,
bring your vehicle to your dealer to have the new
key(s) programmed.
To program additional new unprogrammed key(s),
repeat this procedure from step 1 for each additional
key.

SAFETY RESTRAINTS
Safety restraints precautions
Always drive and ride with your seatback
upright and the lap belt snug and low across
the hips.
To reduce the risk of injury, make sure
children sit where they can be properly
restrained.
Never let a passenger hold a child on his or
her lap while the vehicle is moving. The
passenger cannot protect the child from injury in a
collision.
All occupants of the vehicle, including the
driver, should always properly wear their
safety belts, even when an air bag (SRS) is
provided.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not allow
people to ride in any area of your vehicle that is
not equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
In a rollover crash, an unbelted person is
significantly more likely to die than a person
wearing a safety belt.

Each seating position in your vehicle has a
specific safety belt assembly which is made
up of one buckle and one tongue that are designed
to be used as a pair. 1) Use the shoulder belt on
the outside shoulder only. Never wear the shoulder
belt under the arm. 2) Never swing the safety belt
around your neck over the inside shoulder. 3)
Never use a single belt for more than one person.
Always transport children 12 years old and
under in the back seat and always properly
use appropriate child restraints.
Safety belts and seats can become hot in a
vehicle that has been closed up in sunny
weather; they could burn a small child. Check seat
covers and buckles before you place a child
anywhere near them.
Combination lap and shoulder belts
Before fastening the
safety belt, make sure
the shoulder belt
passes through the belt
guide on the top of the
seatback.
Coupe shown,
convertible is similar
and safety belt must also pass through the belt
guide.
1. Insert the belt
tongue into the proper
buckle (the buckle
closest to the direction
the tongue is coming
from) until you hear a
snap and feel it latch.
Make sure the tongue
is securely fastened in the buckle.

Energy Management Feature
•This vehicle has a safety belt system with an
energy management feature at the front seating
positions to help further reduce the risk of injury
in the event of a head-on collision.
•This safety belt system has a retractor assembly
that is designed to pay out webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the
occupant’s chest.
After any vehicle collision, the safety belt
system at all outboard seating positions
(except driver, which has no“automatic locking
retractor”feature) must be checked by a qualified
technician to verify that the“automatic locking
retractor”feature for child seats is still functioning
properly. In addition, all safety belts should be
checked for proper function.
BELT AND RETRACTOR ASSEMBLY MUST
BE REPLACED if the safety belt assembly
“automatic locking retractor”feature or any other
safety belt function is not operating properly when
checked according to the procedures in Workshop
Manual.
Failure to replace the Belt and Retractor
assembly could increase the risk of injury in
collisions.
