TO DISARM THE SYSTEM
The Vehicle Security system can be disarmed using
any of the following methods:
Push the unlock button on the key fob.
Grab the Passive Entry door handle to unlock
the door Ú page 20.
Cycle the ignition out of the OFF position to
disarm the system.
NOTE:
The driver's door key cylinder and the trunk
button on the key fob cannot arm or disarm the
Vehicle Security system. Use of the door key
cylinder when the system is armed will sound

ttery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will flash,
and the horn will sound. If this occurs, disarm the
Vehicle Security system.
REARMING OF THE SYSTEM
If something triggers the alarm and no action is
taken to disarm it, the Vehicle Security system will
turn the horn off after a 29 second cycle (with five
seconds between cycles and up to eight cycles if
the trigger remains active) and then rearm itself.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm if you lock
the doors using the manual door lock.
TAMPER ALERT
If something has triggered the Vehicle Security
system in your absence, the horn will sound three

CARGO AREA FEATURES
60/40 Split-Folding Rear Seat —
If Equipped
The 60/40 split-folding rear seat provides
cargo-carrying versatility. The seatbacks fold down
easily by pulling nylon tabs between the seatbacks
and the bolsters. When the seats are folded down,
they provide a continuous, nearly-flat extension of
the load floor.
When the seatback is folded to the upright
pos
ition, make sure it is latched by strongly pulling
on the top of the seatback above the seat strap.
WARNING!
Do not allow children to have access to the
trunk, either by climbing into the trunk from
outside, or through the inside of the vehicle.
Always close the trunk lid when your vehicle is
unattended. Once in the trunk, young children
may not be able to escape, even if they entered
through the rear seat. If trapped in the trunk,
children can die from suffocation or heat stroke.
WARNING!
Be certain that the seatback is securely
locked into position. If the seatback is not
securely locked into position, the seat will not
provide the proper stability for child seats
and/or passengers. An improperly latched
seat could cause serious injury.
The cargo area in the rear of the vehicle (with
the rear seatbacks in the locked-up or folded
down position) should not be used as a play
area by children at any time. They could be
seriously injured in a collision. Children should
be seated and using the proper restraint
system.
To help protect against personal injury,
passengers should not be seated in the rear
cargo area. The rear cargo space is intended
for load carrying purposes only, not for
passengers, who should sit in seats and use
seat belts.
