UNLOCK: When  you press the UNLOCK  button, only 
the  driver’s  door will unlock. 
If you  press  UNLOCK again 
within five  seconds, all the  doors will  unlock.  If  you 
would  like all the doors to  unlock  the  first time you press 
UNLOCK,  see  Power  Door 
Locks on  page 2-9 The 
UNLOCK  button on  the  remote  keyless entry transmitter 
will  disarm the content theft deterrent system.  See 
Content  Theft-Deterrent 
on page 2-75 for  more  details. 
(Open Trunk): Press the button with  the trunk 
symbol  to open  your  trunk. The transaxle  must  be 
in  PARK 
(P) for  this feature to operate. 
.& (Remote  Alarm): When  you  press the button with 
the  horn  symbol,  the headlamps  will flash and the 
horn  will sound.  This will allow  you to attract attention 
if needed. 
Your  vehicle  may  have  Remote  Lock/Unlock 
Confirmation. This feature provides  feedback to the 
holder  of the  remote  keyless entry transmitter that 
a  command  has  been  received by the keyless entry 
receiver. 
To signal that  a  command  has been  received, 
the  headlamps  will flash and  the horn  may  sound 
briefly.  See Vehicle Personalization  on page 
2-43 for 
programming  information. 
Matching Transmitter(s) to  Your 
Vehicle 
Each  remote  keyless entry transmitter is  coded  to 
prevent another transmitter from unlocking  your  vehicle. 
If  a  transmitter is lost  or stolen,  a  replacement  can 
be  purchased  through your  dealer.  Remember  to bring 
any  remaining transmitters  with  you  when  you go to 
your dealer.  When the dealer  matches  the  replacement 
transmitter to your vehicle,  any remaining transmitters 
must 
also be  matched.  Once  your  dealer  has  coded  the 
new  transmitter, the  lost transmitter will  not  unlock 
your  vehicle.  Each  vehicle  can  have  a maximum  of four 
transmitters  matched  to  it. 
Battery Replacement 
Under normal  use,  the  battery  in your  remote  keyless 
entry transmitter should  last  about three years. 
You  can  tell the  battery is  weak 
if the transmitter  won’t 
work  at  the normal  range in any  location.  If  you  have 
to  get  close to your  vehicle before the  transmitter  works, 
it’s probably time  to change  the  battery.  

Theft-Deterrent  Systems 
Vehicle  theft is big  business,  especially in  some cities. 
Although  your  vehicle  has  a  number  of theft-deterrent 
features, 
we know that nothing we put on it can  make it 
impossible  to steal. 
Content  Theft-Deterrent 
Your  vehicle  has a theft-deterrent alarm  system. A 
red light located  on top  of the  instrument  panel, 
toward the center  of the vehicle and near the windshield, 
will flash  slowly when the system is  armed. 
While  armed,  the doors will not  unlock with the  power 
door lock switch.  The 
alarm will souad if someone 
tampers with the trunk lock,  enters the vehicle without 
using the  remote keyless entry transmitter or  key to 
unlock the  doors,  or turns the  ignition  on. The  horn will 
sound and the headlamps will  flash for  up to two 
minutes. The system will also cut 
off the  fuel  supply, 
preventing the vehicle from  being driven. 
Arming  with the  Power Lock Switch 
Your  alarm  system can be programmed to  arm when 
you  use either power lock switch  to lock the 
doors while 
any  door  is open and the  key is removed from the 
ignition. 
If you  would  like  to arm  the  system with the 
power lock  switch,  see  Vehicle Personalization  on 
page 
2-43. When  programmed,  the  red light will flash 
quickly to  let you  know that the  system  is ready  to arm 
with the  power lock switches.  When you  press the 
rear  of  a  power door lock  switch, the red  light will stop 
flashing and stay on to  let you  know that the system 
is  arming.  After  all the doors are closed and  locked, the 
red light  will begin flashing  at  a  very slow  rate  to let 
you  know  the  system 
is armed. 
2-1 5  

Arming with the Remote Keyless Entry 
Transmitter 
The  alarm  system will arm  when  you  use  the remote 
keyless entry transmitter  to lock  the doors after the  key 
is  removed  from  the ignition. The red light  will turn 
on  to  let  you know  the system  is arming.  After 
all doors 
are  closed  and locked,  the red light  will begin flashing 
at  a very  slow rate to let  you  know  the  system  is armed. 
Arming  Confirmation 
If the  remote  unlock confirmation  is on,  the  headlamps 
will  flash  briefly to let you  know  when  the alarm 
system  has  armed.  See  Vehicle  Personalization 
on 
page  2-43 for programming information. 
Disarming with the  Remote Keyless 
Entry Transmitter 
The  alarm  system will disarm  when you use  your 
remote keyless  entry transmitter  to  unlock the doors. 
The  red  light will go 
off to  let  you  know  the  system 
is  disarmed. 
Disarming  with Your  Key 
The  alarm  system  will disarm  when  you  use  the  key  to 
unlock  the doors.  The  red light  will stop  flashing 
when  the  system  is disarmed. 
If you  would  like  the  key 
to  disarm  the  alarm system,  see  Vehicle  Personalization 
on page 2-43.
