time will bypass the 30-second
delay and immediately arm the
alarm system.
The vehicle alarm system will not arm
if the doors are locked with the key. If the driver door is opened without
first unlocking with the RKE
transmitter, the horn will chirp and
the lights will flash to indicate
pre-alarm. If the vehicle is not started,
or the door is not unlocked by
pressing
Kon the RKE transmitter
during the 10-second pre-alarm, the
alarm will be activated.
The alarm will also be activated if a
passenger door, the trunk, or the hood

system. When the alarm is activated,
the turn signals flash and the horn
sounds for about 30 seconds. The
alarm system will then re-arm to
monitor the next unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn
off the alarm if it has been activated:
. Press

. Unlock the vehicle using the
Keyless Access system.
. Start the vehicle. To avoid setting off the alarm by

and all doors are closed.
. Always unlock a door with the
RKE transmitter or use the Keyless
Access system.
Unlocking the driver door with the key
will not disarm the system or turn off
the alarm.
How to Detect a Tamper
Condition
IfKis pressed on the transmitter and
the horn chirps and the lights flash
three times, a previous alarm occurred
while the system was armed.
If the alarm has been activated, a
message will appear on the DIC.

Sensor
In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder and inclination sensor.

12460273) - 2019 - CRC - 5/8/18
KEYS, DOORS, AND WINDOWS 45
The power sounder provides an
audible alarm which is distinct from
the vehicle’s horn. It has its own
power source, and can sound an alarm
if the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation.
Immobilizer
SeeRadio Frequency Statement 0373.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the ignition is turned
on or to ACC/ACCESSORY and a valid
transmitter is present in the vehicle.
The security light, in the instrument
cluster, comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
located in the center console.
If the ignition modes will not change
with the other transmitter or in the
transmitter pocket, the vehicle needs
service. If the ignition does change
modes, the first transmitter may be
faulty. See your dealer.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see
“Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 029.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.

Raising the Seatback
{Warning
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
{Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the seat belts are properly
routed and attached, and are not
twisted.To raise a seatback:
1. Lift the seatback up. Make sure the center seat belt and latch do
not get trapped behind the seat.
Push the seatback rearward to
secure it in place.
A red tab near the seatback lever
retracts when the seatback is in
place.
2. Push and pull the top of the seatback to be sure it is in
position.
3. Lock the seatback using the vehicle key in the cylinder.
4. Reconnect the center seat belt mini-latch to the mini-buckle. Do
not let the belt twist.
5. Pull on the center seat belt to make sure the mini-latch is
secure.
6. Repeat the steps to raise the other seatback, if necessary.
When the seat is not in use, it should
be kept in the upright, locked position.
Heated Rear Seats
{Warning
If temperature change or pain to
the skin cannot be felt, the seat
heater may cause burns. See the
Warning under Heated and
Ventilated Front Seats 063.
If equipped, the buttons are on the
rear of the center console.

2. Pick up the latch plate and pullthe belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.If the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.
3. Push the latch plate into thebuckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Seat Belt
Extender 075.
Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
later in this section for
instructions on use and
important safety information.

SEATS AND RESTRAINTS 75
A pregnant woman should wear a
lap-shoulder belt, and the lap portion
should be worn as low as possible,
below the rounding, throughout the
pregnancy.
The best way to protect the fetus is to
protect the mother. When a seat belt
is worn properly, it is more likely that
the fetus will not be hurt in a crash.
For pregnant women, as for anyone,
the key to making seat belts effective
is wearing them properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.But if a seat belt is not long enough,
your dealer will order you an extender.
When you go in to order it, take the
heaviest coat you will wear, so the
extender will be long enough for you.
To help avoid personal injury, do not
let someone else use it, and use it
only for the seat it is made to fit. The
extender has been designed for adults.
Never use it for securing child
restraints. For more information on
the proper use and fit of seat belt
extenders see the instruction sheet
that comes with the extender.
Safety System Check
Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt height
adjusters (if equipped), and seat belt
anchorages to make sure they are all
in working order. Look for any other
loose or damaged seat belt system
parts that might keep a seat belt
system from performing properly. See
your dealer to have it repaired. Torn,
frayed, or twisted seat belts may not
protect you in a crash. Torn or frayed
seat belts can rip apart under impact
forces. If a belt is torn or frayed, have
it replaced immediately. If a belt is
twisted, it may be possible to untwist
by reversing the latch plate on the
webbing. If the twist cannot be
corrected, ask your dealer to fix it.
Make sure the seat belt reminder light
is working. See
Seat Belt Reminders
0 126.
Keep seat belts clean and dry. See Seat
Belt Care 075.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for
and maintained.
Seat belt hardware should be kept dry
and free of dust or debris. As
necessary, exterior hard surfaces and
seat belt webbing may be lightly
cleaned with mild soap and water.
Ensure there is not excessive dust or
debris in the mechanism. If dust or
debris exists in the system please see
the dealer. Parts may need to be
replaced to ensure proper
functionality of the system.
