Illuminated entry
The interior lamps illuminate when the remote entry system is used to
unlock the door(s) or sound the personal alarm.
The system automatically turns off after 25 seconds or when the ignition
is turned to the START or ACC position.
The inside lights will not turn off if:

Replacing the battery
The remote transmitter is powered by one coin type three-volt lithium
battery CR2032 or equivalent. Typical operating range will allow you to
be up to 10 meters (33 feet) away from your vehicle. A decrease in
operating range can be caused by:
²weather conditions
²nearby radio towers
²structures around the vehicle
²other vehicles parked next to the vehicle
To replace the battery:
1. Twist a thin coin between the two
halves of the transmitter near the
key ring. DO NOT TAKE THE
FRONT PART OF THE
TRANSMITTER APART.
2. Place the positive (+) side of new
battery in the same orientation.
Refer to the diagram inside the
transmitter unit.
3. Snap the two halves back
together.

Replacement of the battery willnotcause the remote transmitter to
become deprogrammed from your vehicle. The remote transmitter should
operate normally after battery replacement.
Replacing lost transmitters
Take all your vehicle's transmitters
to your dealer if service is required.
If you purchase additional
transmitters (up to four may be
programmed), perform the following
procedure:
To reprogram the transmitters
yourself, place the key in the
ignition and turn from OFF to ON
four times in rapid succession within
3 seconds. After doors lock/unlock, press any control on all transmitters
(up to four). When completed, turn the ignition to OFF.
All transmitters must be programmed at the same time.
SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
Your vehicle is equipped with a coded-key anti-theft system. Only the
correct key will be able to start your vehicle. If your keys are lost or
stolen, you must take your vehicle to your dealership for key
reprogramming.
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 SecuriLocky
key identification code matches the code stored in the SecuriLocky
passive anti-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 SecuriLockykey is not detected (vehicle theft
situation), the vehicle's engine will not operate.
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 SecuriLocky
ignition 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 top of the instrument panel 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 ON 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 SecuriLockyanti-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.

SEATING
Head restraints
Your vehicle's seats may be equipped with head restraints which are
vertically adjustable. The purpose of these head restraints is to help limit
head motion in the event of a rear collision. To properly adjust your head
restraints, lift the head restraint so that it is located directly behind your
head or as close to that position as possible. Refer to the following to
raise and lower the head restraints.
Push or pull the head rests to the
desired position.
Adjusting the front manual seat
Never adjust the driver's seat or seatback when the vehicle is
moving.
Do not pile cargo higher than the seatbacks to avoid injuring
people in a collision or sudden stop.
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
