Remote Keyless Entry System
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 interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
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 modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
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:
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 objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-6.
If you are still having trouble, see your dealer or a
qualied technician for service.
2-5

Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet
(9 m) away using the remote keyless entry transmitter
supplied with your vehicle.
K(Unlock):Press unlock
for the driver’s door to
unlock automatically, the
parking lamps to ash
and the interior lights to go
on. Press the unlock
button a second time within
three seconds to unlock
all the doors.
You can program different feedback settings through the
Driver Information Center (DIC). For more information
seeDriver Information Center (DIC) on page 3-50.
Q(Lock):Press lock to lock all the doors. Press lock
again within three seconds and the horn will chirp.
L(Panic):Press the horn symbol to make the horn
sound. The headlamps and taillamps will ash for up to
30 seconds. This can be turned off by pressing the
horn button again, by waiting for 30 seconds, or
by starting the vehicle.
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.
2-6

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.
The Driver Information Center (DIC) will display a
RFA # BATTERY LOW message when the transmitter
battery is low.
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 remote keyless entry
transmitter do the following:
1. Insert a thin coin in the slot between the covers of
the transmitter housing. Gently pry the transmitter
apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery,
positive (+) side down.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked.
So, wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
You can use the remote keyless entry system.
You can use your key to unlock your door from the
outside.
You can lock or unlock the door from the inside by
sliding the manual lever forward or rearward. When the
door is unlocked, you can see a red area on the
lever.
The manual lever on each door works only that
door’s lock.
2-8

Power Door Locks
The power door lock
switches are located on
the driver’s and front
passenger’s armrests.
Remove the ignition key and press the lock symbol to
lock all of the doors at once. To unlock the doors, press
the other side of the switch.
Delayed Locking
This feature delays the locking of the doors and the
liftgate when using the power lock or the remote keyless
entry system.
The rst time you attempt to lock the doors with the
driver’s door open, three chimes will signal that delayed
locking is being used. This can be performed by using the
power lock switch or the remote keyless entry transmitter.
All doors and the liftgate can be reopened for up to ve
seconds from the time the last door is closed.
Five seconds after the last door is closed, all the doors
will lock. You can lock the doors immediately by
using the power door lock switch or by pressing the lock
button on the optional remote keyless entry transmitter
a second time.
If the key is inserted in the ignition, this feature will not
lock the doors. The lockout prevention feature will
operate instead.
You can enable or disable the delayed locking feature.
If the feature is disabled, the doors will lock immediately
when a power door lock switch or remote keyless
entry transmitter lock button is pressed.
2-9

Programming Delayed Locking
When your vehicle was shipped from the factory, the
delayed locking feature was programmed on, or
enabled. The mode may have been changed since it
left the factory. To turn the delayed locking feature on or
off, do the following:
1. Press and hold the power door lock switch on the
driver’s door in the lock position.
2. Press the remote keyless entry transmitter unlock
button twice.
If the delayed locking feature was on, it will now be off.
If the feature was off, it will now be on.
Programmable Automatic Door
Locks
Your vehicle is equipped with an automatic lock/unlock
feature which enables you to program your vehicle’s
power door locks. You can program this feature through
the Driver Information Center (DIC), or by the following
method.
Programmable Locking Feature
The following is the list of available programming
options:
Mode 1:All doors lock when the transmission is shifted
into gear.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
Mode 3:No automatic door locking.
The automatic door locks were pre-programmed at the
factory to lock all the doors when the transmission
is shifted into gear. The following instructions detail how
to program your door locks differently than the factory
setting. Choose one of the three programming
options listed above before entering the program mode.
To enter the program mode, do the following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2. Turn the key to RUN and LOCK twice. Then, with the
key in LOCK, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock, the horn will chirp twice, and a
30 second program timer will begin.

Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the liftgate or
liftglass open because carbon monoxide (CO)
gas can come into your vehicle. You can not
see or smell CO. It can cause
unconsciousness and even death. If you must
drive with the liftgate 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 other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-34.
Liftgate Release
To unlock the liftgate, you may use the power door
locks or the keyless entry system described earlier.
On some vehicles the liftglass will also unlock when the
liftgate is unlocked. Press the pushbutton on the
liftglass to open it.
To open the entire liftgate, lift the handle located in the
center of the liftgate. If you open the liftgate, the
liftgate module will lock the liftglass after a one to two
second delay.
Emergency Release for Opening
Liftgate
1. Remove the trim plug to expose the access hole in
the trim panel. The access hole is located on the
inside of the liftgate.
2. Use a tool to reach through the access hole in the
trim panel.
3. Pry the left release lever up to the unlock position.
Pry the right release lever up to unlatch the liftgate.
