Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-Theft Alarm System
This vehicle may have a content
theft-deterrent alarm system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the RemoteKeyless Entry (RKE) transmitter.
The security light should flash. If the delayed locking feature
is active, the alarm will not be
activated until all doors are
closed and the security light
goes off.
3. Close all doors. The security light will stop flashing and go off
after approximately 30 seconds.
The system is armed when the
security light goes off.
If a locked driver door is opened
without using the RKE transmitter,
a 10 second pre-alarm will occur.
The horn will chirp and the lights
will flash. If the key is not placed
in the ignition and turned to START
or the door is not unlocked by
pressing the unlock button on
the RKE transmitter during the
10 second pre-alarm, the alarm
will go off. The vehicle's headlamps
will flash and the horn will sound
for about 30 seconds, then will turn
off to save the battery power. The theft-deterrent system will not
activate if the doors are locked
with the key or the manual door
lock. It activates only if you use
the power door lock switch or the
RKE transmitter. The vehicle can
be started with the correct key if
the alarm is set off.
To avoid setting off the alarm by
accident:
.If you do not want to activate
the theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock a door with the
RKE transmitter.
If the alarm is set off, press unlock
on the RKE transmitter or place
the key in the ignition and turn it
to START.

Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN, ACC/ACCESSORY,
or START from the LOCK/OFF
position. You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it prevents the vehicle
from starting. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and
the security light on the instrument
panel cluster comes on when trying
to start the vehicle, there may be
a problem with the theft-deterrent
system. Turn the ignition off and
try again.

the key appears to be undamaged,
try another ignition key. At this
time, you may also want to check
the fuse. SeeFuses and Circuit
Breakers on page 10‑50. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the PASS-Key III+ to
have a new key made.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. The following
procedure is for programming
additional keys only. If all the
currently programmed keys are
lost or do not operate, you must
see your dealer or a locksmith who
can service PASS-Key III+ to have
keys made and programmed to the
system. See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank cut exactly as the
ignition key that operates the
system.
To program the new additional key:
1. Verify that the new key has
a
1stamped on it.
2. Insert the original, already programmed key in the ignition
and start the engine. If the
engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key. 4. Insert the new key to be
programmed and turn it to
the ON/RUN position within
five seconds of turning the
ignition to the LOCK/OFF
position in Step 3.
The security light will turn
off once the key has been
programmed.
5. Repeat Steps 1 through 4 if additional keys are to be
programmed.

PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to have a new
key made.

If the vehicle is a regular cab,
then all seating positions in the
vehicle have a lap-shoulder belt.
If the vehicle is a crew or extended
cab, then all seating positions in
the vehicle have a lap-shoulder
belt except for the center front
passenger position (if equipped),
which has a lap belt. SeeLap Belt
(Crew and Extended Cab) on
page 3‑26 for more information.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index. 2. Pick up the latch plate and pull
the 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.
Engaging the child restraint
locking feature may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System on page 3‑40
for more information.
If the belt stops before it reaches
the buckle, when using the
lap-shoulder belt in a rear center
seating position of a crew-cab,
tilt the latch plate and keep
pulling the safety belt until it
can be buckled.
