While armed, the doors will not unlock with the power
door lock switch.
Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition to ON. The
horn will sound and the parking lamps will flash for up to
two minutes.
When the alarm is armed, the liftgate may be opened
with the remote keyless entry transmitter or with a key.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
door lock switch to lock the doors while any door or
the liftgate is open and the key is removed from
the ignition. If you would like to turn on power door lock
switch arming, see Vehicle Personalization on
page 2-56 .
When the security light flashes quickly the system is
ready to arm with the power door lock switches.
Then the security light will stop flashing and stay on
when you press the rear of the power door lock switch,
to let you know the system is arming. After all doors
and the liftgate are closed and locked, the security light
will begin flashing at a very slow rate to let you know
the system is armed.
Arming with the Remote Keyless Entry
Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key
is not in the ignition. The security light will turn on to let
you know the system is arming. After all doors and
the liftgate are closed and locked, the security light will
begin flashing at a very slow rate to let you know
the system is armed.
Arming with Your Key
Your alarm system will arm when you use your key to
lock the doors. The security light will turn on to let
you know the system is arming. After all doors and the
liftgate are closed and locked, the security light will
begin flashing at a very slow rate to let you know the
system is armed. If you would like your key not to
arm the system, see Vehicle Personalization on
page 2-56 .
Arming Confirmation
If remote unlock confirmation is on, your parking lamps
will flash briefly to let you know when your alarm
system has disarmed. If you would not like the parking
lamps to flash, see Vehicle Personalization on
page 2-56 .
