even  killed. 
They  could  operate  power  windows  or other 
controls  or even  make  the  vehicle  move.  Don't 
leave  the  keys  in 
a vehicle  with  young  children.

This  vehicle  has  one double-sided  key  for  the ignition  and  door  locks.  It 
will 
fit with  either  side  up. 
When  a  new  vehicle  is  delivered,  the  dealer  provides  the  owner  with  a  pair  of  identical  keys  and  a  key code  number.  The  key  code  number  tells  your  dealer  or  a  qualified 
locksmith  how  to  make  extra  keys.  Keep  this  number  in 
a safe  place.  If  you  lose  your  keys,  you’ll  be  able  to  have \
1ew  ones  madeeasily  using  this  number.  Your selling 
iealer  should  also  have  this  number. 
NOTICE: 
Your  vehicle  has a number  of  new  features  that 
can  help  prevent  theft. But  you  can  have 
a lot of 
trouble  getting  into  your  vehicle  if  you  ever  lock 
your  keys  inside. 
You may  even  have to damage 
your  vehicle 
to get  in. So be  sure  you  have 
extra  keys.

Door Locks 
I 
Unlocked doors can be dangerous. 
Passengers 
-- especially  children -- can easily 
open  the doors  and  fall  out. When a  door is 
locked,  the inside handle  won't open it. 
Outsiders can  easily enter  through  an unlocked 
door when  you  slow  down or stop your  vehicle. 
This may not  be 
so obvious: You increase  the 
chance 
of being  thrown  out of the vehicle  in a 
crash if the  doors  aren't  locked. Wear safety belts 
properly,  lock your 
doors, and you  will  be far 
better off whenever  you drive  your vehicle. 
There  are  several ways to lock and unlock your vehicle. 
You  can use 
the Keyless Entry  System. 
You  can use your key  to unlock your  door  from 
the outside. 
You  can use your power door lock switch 
to unlock your 
doors  from the inside. 
To lock your door  from  the inside, slide the lever on 
your inside door  down. 
To unlock the door, slide the 
lever on your inside  door 
up. You will see a red  area 
on the lever.

Power Door  Locks  Rear  Door 
Security Lock 
With this  feature,  you can 
lock the  rear doors 
so they 
can’t  be  opened 
from the 
inside 
by passengers. 
Move  the lock  up to  lock 
the  doors  and  down 
to 
release  the door  locks. 
The  power  door  lock  switch  is  located  on the armrest. 
Remove  the ignition key  and press 
LOCK to lock all the 
doors  at once. 
To unlock the  doors,  press  the  raised area next  to  the 
key  symbol. 
The  lever  on  each  rear door  works only that door’s  lock. 
Lockout Prevention 
To protect you from  locking  your key in the  vehicle, this 
feature  stops  the power door locks  from locking when 
the key  is in the  ignition and a door 
is open. 
If the  power  lock switch is pressed  when  a  door is open 
and the key 
is in  the ignition,  all the doors will lock  and 
then the driver’s  door will unlock.

Leaving Your  Vehicle 
If you are leaving the vehicle, take your  key, open your 
door  and set the  locks  from  inside.  Then get  out  and 
close  the door. 
Keyless  Entry  System 
You  can lock  and unlock  your  doors  or  liftgate  from 
about 
3 feet (1 m) up  to 30 feet (9 m)  away using the 
remote keyless entry transmitter  supplied  with 
your vehicle. 
Your  keyless entry system  operates on a radio frequency 
subject to Federal  Communications Commission (FCC) 
Rules and with Industry  Canada, 
This  device  complies with Part 
15 of  the  FCC Rules. 
Operation  is subject  to the following two  conditions: 
(1) this device  may  not  cause harmful  interference, 
and 
(2) this  device  must accept any interference 
received, including  interference that may  cause 
undesired operation. 
This  device complies with RSS-210  of Industry  Canada. 
Operation  is subject  to the  following  two conditions: 
(1) this device  may  not  cause  interference,  and (2) this 
device  must accept any interference received,  including 
interference that  may cause undesired  operation of 
the device.  Changes  or 
modifications 
to this system by other  than 
an authorized service facility could  void authorization  to 
use  this  equipment. 
This  system  has a range 
of about 3 feet (1 m) up to 
30 feet (9 m).  At times  you may notice  a decrease  in 
range.  This is normal  for any  remote  keyless entry 
system. 
If the transmitter  does not work  or if you have 
to  stand  closer  to your 
vehicle for the transmitter to 
work, try this: 
0 Check  to determine if battery replacement  or 
resynchronization is necessary.  See the instructions 
that follow. 
Check  the distance. You may be too  far  from your 
vehicle.  You may  need  to stand closer  during rainy 
or  snowy weather. 
Check the location.  Other vehicles  or otqects  may be 
blocking 
the signal. Take  a few steps to the left  or 
right, hold the transmitter higher, and  try again. 
If you’re still having trouble,  see your dealer  or a 
qualified technician  for  service.

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 only four transmitters 
matched  to it.

Battery Replacement 
Under normal use, the battery in your  remote keyless 
entry transmitter should last about two 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. 
NOTICE: 
When  replacing  the  battery,  use  care  not  to touch 
any 
of the  circuitry.  Static from your  body 
transferred 
to these  surfaces  may  damage 
the  transmitter. 
To replace the battery in the keyless entry transrnitter: 
I 
1. Insert a dime in the slot between  the covers  of the 
transmitter  housing  near the key  ring hole. Remove 
the  bottom  by twisting the dime. 
2. Remove  and replace the battery  with a three volt 
CR2032 or equivalent battery, positive (+) side up. 
3. Align  the covers and snap  them  together. 
4. Resynchronize  the transmitter. 
5. Check the  operation  of  the transmitter.

Resynchronization Resynchronization  may  be necessary  due to the security 
method  used by this  system.  The  transmitter does not 
send the 
same signal  twice to the  receiver.  The receiver 
will 
not respond to a signal it has been sent previously. 
This  prevents  anyone 
from recording  and playing back 
the signal from the transmitter. 
To resynchronize your transmitter,  stand  close to your 
vehicle  and press and hold  the LOCK  and UNLOCK 
buttons  on  the transmitter  at the  same  time for  seven 
seconds.  The  door locks  should  cycle to confirm 
synchronization. 
If the  locks  do not  cycle.  see your 
dealer  for  service. 
LiftgateLiftglass 
It  can  be  dangerous  to  drive  with  the  liftgate or 
liftglass  open  because  carbon  monoxide  (CO)  gas 
can  come  into  your  vehicle. You can’t  see  or smell 
CO.  It  can  cause  unconsciousness  and  even  death. 
If‘ you  must  drive  with  the  liftgate or liftglass 
open  or if electrical  wiring  or  other  cable 
connections  must  pass  through  the  seal  between 
the  body  and  the  liftgate 
or liftglass: 
Make  sure  all  windows  are  shut. 
Turn  the  fan  on  your  heating  or  cooling 
system  to  its  highest  speed  with  the  setting 
on any  airflow  selection  except 
RECIRCULATION.  That  will force  outside 
air  into  your  vehicle. See  “Comfort 
Controls”  in  the  Index. 
If you  have  air  outlets  on or under  the 
instrument  panel,  open  them 
all the way. 
See  “Engine  Exhaust”  in  the  Index.
