Preventing Inadvertent Locking Of Passive Entry
Key Fob In Vehicle:
To minimize the possibility of unintentionally
locking a Passive Entry key fob inside your
vehicle, the Passive Entry system is equipped
with an automatic door unlock feature which
will function if the ignition switch is in the OFF
position.
If one of the vehicle doors is open and the door
panel switch is used to lock the vehicle, once all
open doors have been closed the vehicle checks
the inside and outside of the vehicle for any valid
Passive Entry key fobs. If one of the vehicle's
Passive Entry key fobs is detected inside the
vehicle, and no other valid Passive Entry key fobs
are detected outside the vehicle, the Passive
Entry system automatically unlocks all vehicle
doors and chirps the horn three times (on the
third attempt ALL doors will lock and the Passive
Entry key fob can be locked in the vehicle).
To Lock The Vehicle's Doors:
With one of the vehicle's Passive Entry key fobs
within 5 ft (1.5 m) of the driver or passenger
front door handles, push the door handle lock
button to lock all doors.
Push The Door Handle Button To Lock
Do NOT grab the door handle when pushing the
door handle lock button. This could unlock the
door(s).
GETTING TO KNOW YOUR VEHICLE
Do NOT Grab The Door Handle When Locking
NOTE:
After pushing the door handle lock button,

you must wait two seconds before you can
lock or unlock the doors, using either Passive
Entry door handle. This is done to allow you to
check if the vehicle is locked by pulling the
door handle, without the vehicle unlocking.
The Passive Entry system depends on a key

fob that is not fully discharged of its coin
battery capacity.
When the key fob battery is low, the instrument

cluster will display a message indicating that
the key fob battery is low Ú page 15.
